A Multidimensional Readiness Index for the Electriﬁcation of the Transportation System in China, Norway, and Sweden

: The main objective of this paper is to develop a readiness index model that can serve as an analytical tool for exploring the achievements of the electriﬁcation of transportation systems. We have applied this readiness index model to evaluate the readiness positioning of China, Norway, and Sweden towards transportation electriﬁcation. We have chosen these three countries as they represent diversity among countries adopting electric transportation system solutions. Our developed readiness index model has four key dimensions: technological readiness, political readiness, societal readiness, and economic readiness. The embeddedness of all four dimensions in one model provides a multi-perspective way of analyzing and evaluating the readiness levels of countries moving towards transforming their transportation system. Therefore, we named the model a “multidimensional readiness index”. Our main conclusions are that political processes and decisiveness are the most important factors, followed by societal needs and economic ability, with the current technology as the fourth. Without the participation of dedicated and determined political decision makers, the other three factors are challenging to obtain. Political decision makers need to facilitate economic means to support the transformation in society and affected industries to balance the economic disadvantages of the electrically powered vehicle systems until they pass the cost disadvantage turning point. The development of relevant technology is no longer the signiﬁcant barrier it was at the beginning of this transformation about 20 years ago. The technology for electrically powered transportation systems and devices is widely available now, although it is continuously evolving and being improved. Associated industries cannot be expected to initiate, ﬁnance, take risks, and take the lead in this global societal transformation without clear and strong political support.


Introduction
The concept of the electrification of all transportation systems has been rapidly evolving worldwide.Technological innovation in the transportation sector has made it possible to give this concept an actual shape [1].Many contenders derided Toyota when they launched the first hybrid vehicle (Prius) in 1997 [2].In 2003, Elon Musk started Tesla from scratch because of the groundbreaking design and development work he was putting into the powertrain units for his vehicles.It took five years, but Tesla made phenomenally fast progress in entirely new territory.Tesla was not a prior manufacturer that had to diversify to survive, but it was an entrepreneurial startup that did not follow the traditional methods of the automotive manufacturer and came into being to fulfill an intuitively perceived need.Tesla has become the role model of modern electric vehicle development and the developer of high-performance storage and recharging systems for electrified conveyance.Tesla develops and commercializes integrated system solutions, electric cars, charging infrastructure, batteries for their vehicles, and energy storage.Tesla demonstrates a total system solution approach.Some of the significant issues, like the growing environmental warnings, increased pollution problem, and struggle for global market share, forced the transformation of traditional internal combustion engine (ICE) manufacturers towards the electrification of the entire automotive and transportation industry.Also, the old, successful, and prestigious European automakers such as Mercedes, BMW, Audi, and Volvo were finally forced to go electric due to decisive political pressure, new regulations, and new expectations from lawmakers, markets, and customers.Now, in 2021, the most prestigious brands such as Bentley, Porsche, Rolls-Royce, and Jaguar and super brands such as Ferrari and others are adopting electrical solutions with the increasing global awareness of the necessity for all nations to reduce their carbon footprint; nobody can afford to resist moving towards the electrification of transportation.One of the challenges is not 'if' but rather how fast the old automotive industries can transform successfully.The main question will be whether old established brands or newcomers will take the dominant positions in the coming electric vehicles (EVs).
Some countries such as China, Norway, and Sweden have already taken the initiative to an innovative approach to redesigning their governmental policies that support the diffusion of the developed electrified transportation systems (electric vehicles and charging infrastructure are seen as an entire system).Some countries are still in the early stages of development and are moving towards electric transportation systems at a slow pace, whereas others are being rapidly left behind as they are still waiting and wanting to evaluate the success rate of the adoption of all forms of electrified conveyance.The other challenge is which government will 'grasp the nettle' and steer its nation to a position where its citizens accept all necessary initial expenditures and introduce firmly resolved policy making to ensure that all dimensions of the electrification of transportation systems proceed expediently.Thus, the electrification of transportation is becoming a political tool for global competition and battling the environmental consequences of fossil energy.
In this modern era, the technology used in electric vehicles is widely commercially available and possible to obtain in the Asian, European, and USA markets as a commodity.The primary understanding is to know which countries are the buyers and which are the manufacturers, i.e., value creators and wealth distributors, and which countries have the capacity to develop the entire value chain in each country that brings value to the government and industry, and wealth to the people.The electrification of transportation is a complex system associated with energy sourcing and distribution subsystems all the way to electricity consumption [3,4].The entire transportation electrification system is interrelated and interdependent on technology, industrial politics, economic conditions, political and societal domains, and the global competition for controlling market shares.To understand the content and consequences of electrification and handle this transformation, it is necessary to observe, analyze, and evaluate the interconnectivity of readiness levels of all four domains (technology, political, societal, and economic) of the electrification of the transportation system.
Thus, we aim to explore and understand how these factors influence the readiness of each country to go in the electrical direction of the transportation system.Also, we hope that our multidimensional readiness index model can serve and support policymakers in different countries to speed up the electrification process to benefit the environment and citizens of the world.
This paper aims to develop a readiness index model embedded with four dimensions, i.e., technology, political, societal, and economic.The idea of technology readiness is adopted from NASA, while the other three dimensions are empirically derived from our research on the electrification of transportation systems.Together, these four dimensions form the readiness index model that we have used to (i) analyze the development progress, (ii) evaluate the readiness maturity level, and (iii) determine the transitioning position of China, Norway, and Sweden in transportation electrification.This paper also aims to show that the 'multidimensional readiness index model' can assist decision makers in identifying the essential and practical dimensions that can support the process of transforming the transportation system towards electrification.

Research Approach
We have selected China, Norway, and Sweden as empirical grounds to explore their approaches to the electrification of transportation, analyze the different conditions and contextual aspects of importance for the electrification of transportation to identify major critical dimensions, and design the proposed multidimensional readiness index model.China has been chosen as it is currently the dominant and leading country in the electrification of transportation equipment and systems.Norway is one of the most electrified transportation countries globally, and Sweden is one country with ambitions to become one of the world's leading countries in the electrification of transportation.The selected countries are characterized by their aspirations to diligently pursue the electrification of transportation and our explicit understanding of their development directions, although they might choose different paths.Figure 1 represents the research procedure followed in this paper to obtain results that show the readiness of China, Norway, and Sweden in transportation electrification.

Political readiness is interpreted based on government interest and demonstrated actions in transportation electrification, government support to provide subsidies and rebates to EV buyers and manufacturers, and investment in charging infrastructure solutions.Societal readiness is analyzed based on EV sales, market share, and citizens' willingness to adopt EVs.Economics is analyzed based on the economic conditions for the diffusion of EVs, purchasing and charging costs, the operational cost of EVs, and government subsidiaries to support the diffusion of EVs.
This research mainly focuses on passenger vehicles, although there are many vehicles, such as motorcycles, two and three-wheelers, trucks, and buses.The development of heavyduty vehicles, trucks, and buses has recently become commercially available worldwide.Two-wheelers are common in Asia and emerging countries but not in developed countries.The attention to transportation electrification from media and decision makers has been directed to passenger vehicles.For the reasons of the development phases of passenger vehicles and its great attention as the leading automotive industry, our focus was chosen to be passenger vehicles.The readiness model we developed based on our research on passenger vehicles can also be used for other electrified vehicles.Also, trucks and buses, as those aspects included in the readiness analysis and the model, are valid for all other electric vehicles, although the commercial context differs.
To examine each country's technology readiness capabilities, we have used NASA's original model estimating technological readiness while developing the rockets to the moon program as the technological challenges were the most prevailing at that time.The decision to go to the moon was political and embedded in USA politics, supported by the public, and the economy was not considered a restriction.The remaining challenges were technology related.
Thus, the moon project served as inspiration.Still, in the case of the electrification of transportation, the other three dimensions, political, societal, and economic, emerged from our previous research on the electrification of transportation.In our studies of the electrification of transportation in China and Sweden, we have noticed that while technology is receiving significant attention, other dimensions significantly impact the outcome and speed of electrification [5][6][7].In the case of the electrification of transportation, these dimensions cannot be taken for granted.Instead, they must be explored, understood, and put into practice to support the ongoing transformation of transportation electrification.
Our research has developed a 'multidimensional readiness index model' that enables us to explore and understand any transportation mode, including flight and shipping.But, for this research, we have applied the model to China, Norway, and Sweden to evaluate the development progress of these countries in their electrification of transportation systems.We have also developed and classified the political and economic readiness levels based on empirical observations.For societal readiness levels, we were inspired by the European societal readiness levels [8] but adopted them based on our need to focus on the adoption of electric vehicles by society.The pattern of each readiness scale that looks like a thermometer has been adopted from the "KTH Innovation Readiness Level".Each readiness dimension is divided on a scale between 1 and 9.Each of the 1-9 levels show a certain level of readiness; the ninth level shows the highest readiness scoring, whereas the first level shows the lowest readiness scoring of the countries in the electrification of their transportation system.
Finally, results were obtained by evaluating each dimension based on its readiness scoring scales.The score of all dimensions (technology, political, societal, and economic) of each country has been summed up (Σ) and taken out as the percentage (%) by dividing the total score.These mathematical results were used to plot a graph, which shows the positioning of each country in the development of the electrification of their transportation system.
The proposed four-dimensional readiness index scales are tentative and should be further developed, elaborated, and tested.As the diffusion of transportation electrification continues, new technologies will be launched, and new experiences will be developed, thus creating reasons for re-evaluating political, societal, and economic readiness scales to achieve high maturity levels.

Development of the Multidimensional Readiness Index Model
The multidimensional readiness index model is fundamentally sourced from the technology readiness level (TRL) introduced by the National Aeronautics and Space Administration (NASA) in the early 1970s.The multidimensional readiness approach consists of four dimensions: technology readiness levels (TRLs), political readiness levels (PRLs), societal readiness levels (SRLs), and economic readiness levels (ERLs).These four dimensions form a web and, therefore, create a whole system where no one can be left out to gather a broader understanding of the electrification of the transportation system [5], as shown in Figure 2.

We have adopted an innovation perspective to examine the TRL and explore other key components to understand and incorporate them into a system approach.Generally, the term 'innovation' refers to the introduction of new or recombined ideas or methods.However, in the context of this analysis, 'innovation' is also about using technology to succeed with commercialization, value creation, and diffusion in society via a suitable business model.The technological element is merely one of the essential dimensions of the business concept.The technology requires a proper and relevant context to be embedded and integrated for commercialization.Economic, societal, and political acceptance are the main elements needed for a potential technological solution to become a successful innovation accepted by most of the market.Regarding some of the most successful innovations in our society, such as fast trains, airplanes, electric vehicles, and smartphones, we can see that they are all rooted in the political, economic, social, and socio-cultural contexts of their respective eras.We have adopted an innovation perspective to examine the TRL and explore other key components to understand and incorporate them into a system approach.Generally, the term 'innovation' refers to the introduction of new or recombined ideas or methods.However, in the context of this analysis, 'innovation' is also about using technology to succeed with commercialization, value creation, and diffusion in society via a suitable business model.The technological element is merely one of the essential dimensions of the business concept.The technology requires a proper and relevant context to be embedded and integrated for commercialization.Economic, societal, and political acceptance are the main elements needed for a potential technological solution to become a successful innovation accepted by most of the market.Regarding some of the most successful innovations in our society, such as fast trains, airplanes, electric vehicles, and smartphones, we can see that they are all rooted in the political, economic, social, and socio-cultural contexts of their respective eras.
The diffusion and deployment of technologies are based on social acceptance; without being socially accepted, technology for technology's sake will face endless public resistance.It will be difficult to achieve commercial success for technology and attract investment and partners if political, institutional, and regulatory players do not support it.Therefore, the acceptance of developed technologies needs to be observed and examined in the context of a complex web of interactions that includes technical, political, societal, and economic elements.
Thus, the technology readiness levels can be used to evaluate technology readiness.The political readiness levels express the dedication and willingness of the government to adopt and promote technology in the country.The societal readiness levels show the technology's adoption rate, and whether society supports the technology.The economic readiness levels demonstrate the affordability of the technology for the buyers to consume the product.Thus, all the readiness levels are interdependent and interrelated.However, the role of the political readiness levels is the most significant in holding the other three readiness levels in one net to support the transformation.

Technology Readiness Levels (TRLs)
The technology readiness level (TRL) is an approach for conducting a logical analysis, assessment, and decision-making process when selecting an appropriate technological solution based on the maturity of technologies.The TRL has become a standard approach to measuring a particular technology's maturity.Fundamentally, the TRL determines whether technologies are ready for adoption by potential consumers [9].Level 1 is considered the lowest and level 9 is the highest for measuring the criterion on the TRL scale.Figure 3 demonstrates all nine TRLs [9].

The initial findings are collected and multiple parameters are tested.At this level, active research and design are initiated for a particular technology.When basic concepts have been investigated and practical applications may be developed based on those results.However, TRL 2 could be risky as there is no empirical evidence that the technology exists.The beginning phase of any technology is when the conceptual study is translated and reported for future research and development.

Political Readiness Levels (PRLs)
In our experience, technology has been one of the most critical driving forces of societal and industrial transformation.The advancement of technology has introduced various technological solutions for decarbonizing the environment, such as renewable energy, transportation electrification, hydrogen-based transportation, etc.However, large-scale R&D implementing new technical solutions and the diffusion of new technologies are almost impossible without political decisiveness and determination to utilize technology to transform and develop society.This is especially valid for the electrification of transportation as transportation is one of the most harmful environmentally impacting industrial sectors globally.At the same time, it is directly associated with the coal and oil industry, an economic engine and a significant employer of many countries that will lose out when the transportation system is electrified.Some suggest that this ongoing electrification of the European automotive industry might lead to about 500,000 people losing their current jobs [10].Political readiness is seen when politicians recognize the problems and challenges and provide immediate support in framing new regulations, laws, and policies to support economies, industries, and consumers to be able to purchase expensive but desirable technologies that are costly in the beginning.Figure 4 explains the nine PRLs.

The idea is discussed in a cabinet meeting where local, regional, and state governments show their willingness to move forward and develop the action plan. 1 The head of the state publicly expresses their interest in moving towards new innovative ideas/inventions or adopting new technology.

Societal Readiness Levels (SRLs)
The societal readiness level is a scale for analyzing and evaluating the readiness level of societal acceptance; for example, a product or a technology to be integrated into society needs to be accepted and desired by its citizens.Suppose we continuously design technologies, infrastructure, and policies in which people are not incorporated and do not see the benefits for them and their lives.In that case, there will be a risk in moving towards electrified solutions because it could be a failure [11].SRL 1 is the lowest and SRL 9 is the highest level of readiness, indicating that society has already started adopting new technologies or products.Figure 5 demonstrates all nine SRLs [8].

SRL Description
The product is diffused in society, and many citizens buy the product.Business development and product commercialization are completed, and the product's initial sales begin.The citizens and the relevant stakeholders test the first product and confirm the benefits.Establishing a business relationship by demonstrating the solutions with the customers and the relevant stakeholders.Customers' and stakeholders' views confirm the proposed solutions' success rates in the specific area.The proposed solution is tested by collecting the views of the customers and relevant stakeholders through pilot projects.Suitable solutions that best fit the problems and awareness of these are provided to citizens and relevant stakeholders.To specify the needs or problems of society, some market research is performed mainly based on secondary data.In the initial stage, problems are identified, such as environmental problems, customer needs, or factors associated with human health, etc.

Economic Readiness Levels (ERLs)
The economic readiness level is a dimension for analyzing and evaluating the readiness levels of the cost affordability of a technology or a product by the industry that impacts them and the large number of citizens expected to adopt electric vehicles.Economic readiness is essential in diffusing innovative products (electric vehicles) into society.The consumer's approach is to pay for something less expensive or better than they already have.
The word "economic" is a vast subject divided into microeconomics and macroeconomics.Microeconomics is a bottom-up approach that deals with individual business decisions and concentrates on supply and demand that forces the determining of price levels.Macroeconomics is a top-down approach that deals with decisions made by governments and countries.It focuses on the economy, where the government determines the R&D investments and prices, imposes and reduces taxes, and provides rebates and subsidies to balance the development and manufacturing costs for early technologies with the price level of the products in the market [12].After all, the business operators and citizens must be able to afford to buy the new technology and products.
The transformation of the transportation system is a national and international matter that involves facing national and international challenges such as global warming, pollution, and depletion of fossil fuels in the world.Being responsible nations, it is each country's government's responsibility to deal with these challenges and support the transformation of the transportation system towards electrification.Therefore, we used the macroeconomic concept to build the economic readiness levels where the government controls the prices to bring stability and affordability to the market.The government has the mandate to manage and set the minimum or maximum prices for specific products, including gasoline, electricity, and vehicles [13].
To develop the economic readiness levels, we focused on balancing the cost of three main factors (the manufacturing cost of EVs, energy supply for the transportation infrastructure, and operational cost), which governments can support by providing subsidies, rebates, and imposing/reducing taxes on EVs to push EVs in the market for societal diffusion to achieve certain benefits, for instance, decarbonizing the environment and relying less on fossil fuels.The government can support this until the economic readiness reaches the highest level where the price balances out for consumers and producers, which means that the consumers can afford the product, and the producers can still capture the value.

ERL Description 9
The EV purchasing and operational costs become equal to or less than gasoline-based vehicles. 8 The government provides affordable/free charging facilities at public charging stations, affordable/free charging piles at public parking, or supports installing charging piles at home.This act will reduce the operational cost of EVs for citizens.

7
The government reduces/eliminates the registration and insurance fees on EVs, which will further support citizens in the cost reduction of purchasing EVs compared to gasoline-based vehicles.6 The government provides extra support to encourage citizens to buy EVs by offering subsidies and rebates.5 The government reduces/eliminate taxes on EV purchase for citizens to control the initial cost of EVs.

The government also supports renewable energy providers by eliminating/reducing taxes for those who provide energy to the EV infrastructure. 3 The government provides extra support to encourage automotive manufacturers to produce electric vehicles by offering subsidies and rebates. 2 The government reduces/eliminates taxes for companies producing electric vehicles and charging equipment.Table 4 illustrates the nine levels of government involvement to prepare economic readiness for each stakeholder participating in the transformation of the transportation system.The technology, political, and societal readiness levels are more general readiness levels that can be used for any technological, political, or societal context, but the economic readiness levels depend on the development requirement of the product and the context where the product will be used.

Economic readiness is a complex dimension that contains various interrelated and interdependent factors such as government policies related to import/export, manufacturing companies' capabilities (they either have complete value chain capability or need to import the parts for manufacturing the product), and market behavior.Not all the products require the same or specific infrastructure to operate.For instance, the airline and shipping industry follows international laws, customer segments vary from country to country, and airplane manufacturers are limited.So, the economic policies are designed by considering these factors, which do not apply to the automotive industry.Therefore, the economic readiness levels are explicitly developed for the electrification of transportation systems because economic readiness depends on the import/export policies of the government, which require specific infrastructure and the support of energy companies to operate electric vehicles.ing companies' capabilities (they either have complete value chain capability or need to import the parts for manufacturing the product), and market behavior.Not all the products require the same or specific infrastructure to operate.For instance, the airline and shipping industry follows international laws, customer segments vary from country to country, and airplane manufacturers are limited.So, the economic policies are designed by considering these factors, which do not apply to the automotive industry.Therefore, the economic readiness levels are explicitly developed for the electrification of transportation systems because economic readiness depends on the import/export policies of the government, which require specific infrastructure and the support of energy companies to operate electric vehicles.However, another implemented charging infrastructure solution has been developed for operating EVs as a complementary charging solution, which is battery swapping technology.The Chinese government has put battery swapping and hydrogen technology on the national strategic agenda.Hydrogen has been mulled as an alternative fuel for ICE-powered vehicles as an alternative to hydrocarbon-based fuels, thus representing a further means of reducing the carbon footprint.Electric vehicle manufacturers' key leaders (NIO, Geely, BJEV, and Changan New Energy) have adopted battery swapping technology.By the end of June 2020, there were 452 battery swapping stations in China.The growth of battery swapping stations continued and reached over 716 battery swapping stations by the end of June 2021.Estimations indicate there will be 25,000 swapping stations in 2025 for passenger vehicles [6] and more than 400 swapping stations for heavy trucks in a few years [7].The electrification of Chinese mega-cities is complex and complicated to manage through cable charging solutions only.Thus, swapping systems are introduced as complementary systems.Therefore, China is positioned at level 9 in the technology readiness levels of the multidimensional readiness index.

In 2009, the central government of China started subsidizing EV sales for public and government fleets, and in 2013, it began supporting private EV owners.The subsidies were between USD 5400 and USD 9000 per vehicle in 2013, depending on the vehicle's electric range.At the end of 2020, the government introduced a new EV subsidy policy for 2021.According to the new policy, 20% of the subsidy was reduced to pure electric vehicles.Vehicles with a driving range between 300 and 400 km dropped from USD 2500 to USD 2000 per vehicle, and vehicles with a driving range of 400 km or more decreased from USD 3500 to USD 2800 per vehicle.In addition, for hybrid vehicles, the subsidies dropped from USD 1320 to USD 1050 per vehicle.The unexpected drop of 20% for the subsidy on EVs sharply decreased the sales of EVs in the industry.The government extended the EV subsidy support for two years until the end of 2022 to get the market back on track.The sales of EVs rebounded when the government approved the extension [16].
The Chinese government decided, in May 2020, to include battery swapping technology as a national strategic development technology, which handles a new infrastructure policy focusing on the battery's whole life cycle value.By the end of 2020, battery swapping technology was highly supported in the most significant Chinese national policy that drives industrial development in China, "The new energy vehicle development plan 2021-2035" [6].Battery swapping has become attractive to drivers since it decreases upfront costs and reduces recharging time.In 2020, NIO introduced a new business model based on unbundling vehicle purchases, battery renting, and swapping subscriptions.The four major Chinese electric vehicle manufacturing companies that provide battery swapping services are NIO, Geely, BJEV, and Changan New Energy.Standardizing battery swapping services has been a priority for the Chinese government.In April 2020, the Chinese government extended the subsidies for EV manufacturing companies, with the condition that companies will only be eligible for grants if the prices of EVs are below about USD 46,000.However, this policy does not apply to battery swapping models.The policy indicates that most premium electric vehicle manufacturers will have to decrease their EV prices to meet the requirements for the subsidy scheme, and the policy also shows the clear intention of the government to boost the battery swapping business in China.The Chinese Finance Ministry has announced a cut of 30% of subsidies on new electric vehicles (NEVs) in 2022 and eliminate the subsidies from 31 December 2022 [17].China will become the first country to eliminate all sorts of subsidies on NEVs by the end of this year, which might affect the sales of NEVs.However, the overall interest of the Chinese government in the diffusion and adoption of sustainable electrified transportation is very high.Therefore, China is placed at level 9 in the political readiness levels of the multidimensional readiness index.

Societal Readiness Level in China
Chinese society has been introduced to the concept of electrification for more than 20 years.In 2019, battery electric vehicle (BEV) sales reached almost one million, three times more than plugin hybrid electric vehicles (PHEVs).The sale of electric vehicles continuously increased in 2020, reaching over one million.In July 2021, 271,000 electric vehicles were sold in China, nearly breaking another monthly record.Compared to July 2020, 164.4% of electric vehicle sales increased in just one year, indicating that the electric vehicle sector is booming, with numerous brands and models selling in large numbers.The overall market share of EVs, including 12% BEVs and 3% PHEVs, increased and reached 15% in the middle of 2021 [18].In the six largest Chinese cities, electric and hybrid vehicles now account for an average of a fifth of new car sales.Consumers in China's industrialized cities on the east coast have adopted electric vehicles more rapidly than their inland counterparts.The electric vehicle penetration rate in major cities is 8% higher than in other cities of China, like Shanghai 31%, Beijing 16%, Guangzhou 13%, Shenzhen 25%, Hangzhou 21%, and Tianjin 12% [19].Ten years ago, the 12 million inhabitants of the city of Shenzhen introduced electric vehicles as large-scale buses for the initial electrification of the public transportation domain.Now, Shenzhen has 22,000 EV taxis, 18,000 EV buses, and 86,000 EV logistic vehicles.Now, ordinary people see that the next step is the full electrification of private vehicles.Chinese society is committed to moving expeditiously towards sustainable transportation based on a fully electrified, fossil-fuel-free transportation system.Therefore, China is positioned at level 9 in the societal readiness levels of the multidimensional readiness index.

Economic Readiness Level in China
The economic readiness analysis is based on the electric vehicle cost, the operational cost of the vehicle, subsidiaries' support to make the price and cost affordable for citizens and businesses, and the outcome in terms of value creation to the country and people.A survey was conducted in June 2019 by 'Rakuten Insight' on the "Acceptable price level for purchasing an electric car compared to a conventional car in China".Almost 26% of Chinese consumers are only willing to pay the same price for an electric car as a conventional car, whereas 18.8% of consumers agree to pay up to 10%, and 22.4% of consumers are ready to pay 11 to 30% higher than for conventional cars [20].In total, 45% of consumers are willing to pay a higher price for electric vehicles than traditional cars.In contrast, only 8% of consumers are unwilling to pay a higher price for electric vehicles than conventional cars.It means more people favor electrified transportation in China besides the cost of the electric vehicle.One explanation is that electric vehicles bring health improvements to citizens, especially in highly dense cities, and are values for which citizens are ready to pay.
The price of electric vehicles is continuously dropping in China.Consumers attained cost competitiveness on electric vehicles many years earlier than expected, primarily due to fuel savings.In 2022-2026, electric cars will provide a compelling new vehicle purchase proposition based on analyzing the first owners' 5-year vehicle ownership expenses.Electric vehicles' fuel and maintenance savings greatly surpass home chargers and other expenditures for the first buyers in 2025.The BEV ranges of 250-500 km and PHEV ranges of 40-100 km is compared to the conventional cars in these two categories.In 2020, the initial prices of electric vehicles were USD 5000 to USD 17,000 more than similar to gasoline vehicles.By reducing the cost of components and subsystems and assembling EVs and EV batteries, the projected prices of a short-range BEV in 2026 and a long-range BEV in 2030 will equal their counterpart gasoline vehicles.The charging cost of electric vehicles depends on the electricity prices provided by the grid.Since China wants to encourage the use of electric vehicles, the charging prices have been set at low levels.There are time-of-use fees for EV charging in several provinces and cities in China.The State Grid's charging stations also use time-of-use pricing.State Grid Beijing costs RMB 1.0044/kWh (approximately USD 0.16) during peak hours, RMB 0.6950/kWh (approximately USD 0.11) during shoulder hours, and RMB 0.3946/kWh (approximately USD 0.062) during off-peak hours, plus a service fee RMB 0.8/kWh (approximately USD 0.13) [21].However, the cost of electric vehicles is still not competitive compared with gasoline vehicles, and mostly, the subsidies and rebates encourage people to buy electric vehicles.Estimations are made that the EVs will be price-neutral to ICE technology in 3-5 years.Therefore, China is placed at level 8 in the economic readiness levels of the multidimensional readiness index.

Norway 4.2.1. Technology Readiness Level in Norway
Norway does not produce electric vehicles but primarily imports them from other countries.The top 10 selling brands of electric vehicles in Norway in September 2021 were imported from the Czech Republic (Skoda), Germany (Volkswagen and Audi), Japan (Nissan and Toyota), South Korea (Hyundai), and the USA (Ford and Tesla), as shown in Figure 8 [22].
in 2030 will equal their counterpart gasoline vehicles.The charging cost of electric vehicles depends on the electricity prices provided by the grid.Since China wants to encourage the use of electric vehicles, the charging prices have been set at low levels.There are timeof-use fees for EV charging in several provinces and cities in China.The State Grid's charging stations also use time-of-use pricing.State Grid Beijing costs RMB 1.0044/kWh (approximately USD 0.16) during peak hours, RMB 0.6950/kWh (approximately USD 0.11) during shoulder hours, and RMB 0.3946/kWh (approximately USD 0.062) during off-peak hours, plus a service fee RMB 0.8/kWh (approximately USD 0.13) [21].However, the cost of electric vehicles is still not competitive compared with gasoline vehicles, and mostly, the subsidies and rebates encourage people to buy electric vehicles.Estimations are made that the EVs will be price-neutral to ICE technology in 3-5 years.Therefore, China is placed at level 8 in the economic readiness levels of the multidimensional readiness index.In May 2021, NIO China, a BEV manufacturing company, started operating in Norway to provide a fully-fledged ecosystem incorporating cars, services, and charging infrastructure.NIO Norway has introduced its first smart electric vehicle model, the NIO ES8 SUV, which was available on 3 September 2021, at Honefoss Airport for a test drive.NIO provides a total system solution offering electric vehicles supported by charging infrastructure, battery swapping systems, and cable charging solutions.NIO plans to establish In May 2021, NIO China, a BEV manufacturing company, started operating in Norway to provide a fully-fledged ecosystem incorporating cars, services, and charging infrastructure.NIO Norway has introduced its first smart electric vehicle model, the NIO ES8 SUV, which was available on 3 September 2021, at Honefoss Airport for a test drive.NIO provides a total system solution offering electric vehicles supported by charging infrastructure, battery swapping systems, and cable charging solutions.NIO plans to establish 20 battery swapping stations in Norway in 2022, and one is already operational outside Oslo.Sweden will follow in 2022 with 10 swapping stations, followed by Denmark.
Norway has a lower population density than many other European nations and a relatively high percentage of private house ownership.Installing personal home-based electric vehicle chargers is simple, and many electric vehicle owners utilize them as their primary power source.The Norwegian Electric Vehicle Association sent out a survey in 2017 in which electric vehicle owners living in apartments and houses were asked how often and where they charged their vehicles.The results indicate that electric vehicle owners rely very little on public charging and more on charging EVs at home or work [23].However, the lack of public chargers challenges travelers and tourists.
With its geographical factor, Norway is a long country with a low population, and the driving range between cities is long.Well-organized public charging infrastructure is required for long-distance travel.For this purpose, in 2017, the Norwegian government started funding to install at least two multi-standard fast chargers with cable-based charging stations every 50 km along all of Norway's major highways.
One factor that will affect the technology readiness in Norway is the massive pressure on the nation's electrical grid due to the substantial number of electric vehicles conventionally charged simultaneously, i.e., with charging stations or outlets.In that case, the power grid can experience massive stress spikes during peak hours.However, the stress on the power grid can be flattened out by charging the vehicles outside the peak hours and ensuring that every charging station has a solar panel array and battery storage to help reduce the peak loads drawn from the grid.The charging infrastructure is mainly private, and the lack of public charging piles is a barrier to the diffusion of BEVs.Besides having a well-organized home-based charging system, Norway is far behind in technology readiness, as Norway has to import each component used for electrification from other countries.Therefore, Norway is positioned at level 5 in technology readiness levels of the multidimensional readiness index.

Political Readiness Level in Norway
Norway introduced policies to encourage the use of electric vehicles by temporarily eliminating the import tax in the early 1990s.The Norwegian government has also launched various incentives (access to driving on the bus lanes, limited parking fees, and no road tolls) for electric vehicles to eradicate vehicles and on-road taxes that reduce the upfront and lifetime cost of electric vehicles.The government aims to have all new vehicles sold from 2025 be electric or hydrogen-driven.The incentives for electric and hydrogen-fueled vehicles can be considered the Norwegian government's strategy to promote electrification in Norwegian society.
In Norway, the existing electric vehicle policy incentives stabilized and successfully established the electric vehicle market, and in return, a profitable second-hand EV market emerged in Norway.The electric vehicle market is well established in the main cities of Norway, like Bergen and Oslo, whereas the electric vehicle market in rural areas is rapidly growing.One of the most prominent incentives applied in Norway is the 'vehicle tax system', which allows the electric vehicle to become price competitive with ICE vehicles.The 'tax system' is based on the vehicle's weight, carbon dioxide and nitrogen oxide emissions, and value-added taxes.These combined taxes make EVs affordable to buy or import with very few added costs compared to ICE vehicles, which sometimes cost more than double the import price [24].These are some of the most significant incentive policies the Norwegian government has implemented that have led Norway to the massive adoption of electric vehicles.
The Norwegian government is working towards future policies to meet the goals of the Paris Agreement to reduce the nation's greenhouse gases by 40% by 2030 compared with the levels of the 1990s.Furthermore, the country is striving towards the following three goals to meet the criteria of the Paris Agreement [25]:

•
All new private vehicles must be purchased in zero-emission configuration or using biogas by 2025.

•
The distribution of all goods must be by near-zero-emission vehicles in major cities by 2030.

•
All new heavy vans, 75% of new long-distance buses, and half of all new trucks must be of zero-emission status by 2030.
Norway is at the global forefront of adopting electric transportation.The Norwegian government played a decisive role in promoting electric vehicles by implementing favorable incentives policies.Therefore, Norway is positioned at level 9 in the political readiness levels of the multidimensional readiness index.

Societal Readiness Level in Norway
Norway has already become the leading country in the world to sell more electric vehicles than vehicles with diesel, petrol, or hybrid engines in 2020.In the same year of 2020, Norway broke a global record by selling 54.3% of all new battery electric vehicles.In contrast, in 2019, it was 42.4%, which means the sale of battery electric vehicles increased by 11.9% in only one year.This was achieved even though Norway is an oil-producing country.Norwegian policy exempts taxes for fully electric vehicles and imposes taxes on vehicles run by fossil fuels.The goal of the Norwegian government is to become the first country in the world to stop selling new diesel or petrol cars by 2025 [26].In March 2021, 8624 electric passenger cars and 4379 plugin hybrid vehicles were sold.The sales of fully electric vehicles are increasing, whereas plugin hybrid vehicle sales (PHEV) are declining.In March 2020, the sales of PHEV were 83.1%, but in March 2021, the sales of PHEV were at 28.6%, meaning PHEV sales declined by almost 54.5% in one year.However, it is still higher than the sales of vehicles run on diesel and petrol (4.7 and 4.8 percent, respectively) [27].Norway is a rich country where people are paid handsome salaries.The costs of generating and distributing electrical energy in Norway are very high.But consumers are willing to pay a premium fee for the fast-charging service as it costs them three times less than what they pay for electricity at home.We place Norway at level 9 in the societal readiness levels in the multidimensional readiness index.

Economic Readiness Level in Norway
In Norway, ten years ago, nobody could even predict that there would be more electric cars than non-electric in 2021, and there are not only cars that have gone electric, but bikes, trams, trains, and buses have all become propelled by electrical means.The Norwegian government policies and the incentives for the buyers are the leading cause for the rapid transition of the transportation system from fossil-based fuels to electric in Norway.The key to accelerating EV adoption in Norway was to make them affordable.The government reduced taxes and even exempted road toll tax to keep the operating cost for EVs down [28].
Buying an electric vehicle is also cheaper than purchasing a petrol-fueled car in Norway.In November 2020, the new Volkswagen Golf (petrol) price was higher than the Volkswagen Golf (electric).To encourage buyers to buy EVs, the Norwegian government reduced other taxes to make them affordable.The operational cost of EVs is much lower than that of gasoline vehicles.
Driving an electric vehicle for an operating distance of 12,300 km/year, which is moderate, can save NOK 12,000 (approximately USD 1355).The service cost for electric vehicles is generally lower since there are fewer moving components than for gasoline vehicles.In addition, the traffic insurance tax is far lower for EVs in Norway [29].Thus, Norway is positioned at level 9 in the economic readiness levels of the multidimensional readiness index.

Sweden 4.3.1. Technology Readiness Level in Sweden
Sweden is an innovative industrial country.The Swedish automotive manufacturing company Volvo is now owned by the Chinese vehicle manufacturer Geely.In 2021, Volvo introduced two new EV brands, Volvo and Polestar, which are so far manufactured in China.However, the top 10 selling brands of electric vehicles in Sweden in September 2021 are imported from various countries, such as the Czech Republic (Skoda), Germany (Audi and Volkswagen), Japan (Nissan), South Korea (Kia), China (MG), and the USA (Ford and Tesla), as shown in Figure 9 [30].
In Sweden, several alternative EV charging technologies are in the testing phase, such as dynamic (conductive and inductive), semi-dynamic, and static charging, and they are looking for further battery swapping solutions.Static charging is considered a relatively mature technology primarily used to charge passenger vehicles.However, heavy-duty vehicles (HDVs) can utilize the current chargers used by cars.Still, it takes longer to charge the battery due to the battery capacity of heavy-duty vehicles.In Sweden, charging stations have gradually increased during the last three years, crossing almost 10,000 units with type 2 sockets and 610 charging stations with CCS/Combo sockets until mid-2020 [31].

The electric trucks manufactured by Volvo and Scania can be charged through static chargers by using the latest CCS type 2 connectors.However, these CCS type 2 connectors are intended to charge regular EVs, not HDVs like Volvo's FE/FL and Scania's BEVs.Volvo and Scania chose to use the existing charging solutions because of the lack of fast chargers designed for HDVs and the high demand for electric trucks.The fast chargers for HDVs are available on the market and have been implemented in three major cities in Sweden.These fast chargers adapted for HDVs have a higher charging power and are less timeconsuming than chargers for light vehicles.Installing fast chargers for HDVs near the most operated transportation routes is crucial to aid electric truck diffusion.Moreover, the European Union and its members collaborate to develop and implement a common standard for Megawatt chargers [32].
Sweden is working on static and dynamic (conductive and inductive) road charging, meaning vehicles can charge their batteries in motion.Sweden has built its first electric roads for demonstration purposes at Arlanda (1.2 miles long), Sandviken, Lund city, and The electric trucks manufactured by Volvo and Scania can be charged through static chargers by using the latest CCS type 2 connectors.However, these CCS type 2 connectors are intended to charge regular EVs, not HDVs like Volvo's FE/FL and Scania's BEVs.Volvo and Scania chose to use the existing charging solutions because of the lack of fast chargers designed for HDVs and the high demand for electric trucks.The fast chargers for HDVs are available on the market and have been implemented in three major cities in Sweden.These fast chargers adapted for HDVs have a higher charging power and are less time-consuming than chargers for light vehicles.Installing fast chargers for HDVs near the most operated transportation routes is crucial to aid electric truck diffusion.Moreover, the European Union and its members collaborate to develop and implement a common standard for Megawatt chargers [32].
Sweden is working on static and dynamic (conductive and inductive) road charging, meaning vehicles can charge their batteries in motion.Sweden has built its first electric roads for demonstration purposes at Arlanda (1.2 miles long), Sandviken, Lund city, and Visby city.Sweden is further working on wireless charging and looking for complementary charging solutions such as battery swapping technology.However, these technologies are still in the demonstration and testing phase on a small scale.On the other hand, inductive charging, considered a reliable solution, is in the development process.The charging output is limited, facing the technical standardization problem.Therefore, Sweden is positioned at level 6 in the technology readiness levels of the multidimensional readiness index.

Political Readiness Level in Sweden
Swedish policies support the transformation of the transportation system from fossilfueled vehicles to electric vehicles and offer several incentives to electric vehicle owners.Sweden is transitioning to electrified vehicle transportation systems with a 26% EV market share and a 253% rise in EV sales in 2019.Sweden has increased incentives such as municipal incentives, tax rebates, and government grants, contributing to the rising popularity of electric vehicles.In 2007, the Swedish government introduced a program called the "Green Car Award".This program aimed to offer a tax credit of SEK 10,000 (approximately USD 1166.45) for new vehicles that satisfied the specified emission standards.The impact of the green car award program was positive, and this program raised the market share of green cars (with emissions of 50 g CO 2 /100 km or less); however, it is claimed that the majority of buyers would have purchased green vehicles regardless of the subsidies being offered [33].
The Swedish government plans to reduce 70% of greenhouse gas emissions of its present level from the transportation sector by 2030.To achieve this target, the government has further introduced a scheme of subsidies for low-emission cars serviced before 2020 with CO 2 emissions of up to 60 g/km and vehicles serviced during 2020 or after with CO 2 emissions of up to 70 g/km in the form of a grant of SEK 60,000 (approximately USD 6998.70).These subsidies are available for up to 25% of the new car's purchase price.This scheme applies to both individuals and businesses.Similarly, the grants are available for heavy-duty vehicles, especially for public transportation agencies, municipalities, and small businesses; a grant of 20% of the EV bus purchase price is available.
Furthermore, the incentive covers 40% of the difference between the cost of an electric bus and a comparable diesel bus for private transportation businesses.The Swedish government is also focusing on the development of charging infrastructures.The number of charging units has increased from 500 to 10,000 between 2012 and 2020.The major cities in Sweden, such as Stockholm, Gothenburg, and Malmö, also provide local charging incentives for EV owners.In Stockholm, the free charging of BEVs and PHEVs is available for parking space subscribers; only non-electric vehicle owners have to pay the parking fee.The local government of Gothenburg decided to install 500 new charging stations in the city's public parking areas during the autumn and winter of 2020 and 2021.Malmö has more than 150 public charging stations.The chargers have different speeds; some are fast chargers of up to 22 kW/h, whereas others have only up to 3.7 kW/h to charge electric vehicles.The local government of Malmö is planning to equip 20% of parking spots with EV charging stations [34].However, while static charging is considered a reliable charging source, EV drivers face technical standard problems with different sockets used at different charging stations for a plugin to charge a vehicle.The absence of institutions and policymakers is prevailing.The role of institutions and policymakers is required to develop and implement a common standard plug connection for static charging.On the other hand, the dynamic solution (electric road technology) is still in the testing phase.Therefore, Sweden is located at level 7 in the political readiness levels of the multidimensional readiness index.

Societal Readiness Level in Sweden
Sweden is a well-educated society with substantial awareness of environmental concerns.Swedish society is rapidly adopting electric vehicles.In February 2020, Sweden's market share of electric and plugin hybrid cars reached 24.3%.The rapid adoption of electric vehicles has increased in Sweden since the Swedish government introduced a new subsidy scheme in January 2020.
In February 2020, around 6.4% of all new registered Swedish cars were battery electric vehicles (1430), and approximately 18% were plugin hybrids (4027).Compared with February 2019, electric car sales have increased by 112% and plugin hybrid vehicles by 59%.In January 2020, around 7.1% of all new cars registered were battery electric vehicles (1269), and about 23.1% were plugin hybrids (4113).Compared with January 2019, the sale of battery electric vehicles increased by 15% and plugin hybrid vehicles by 160.8% [35].The adoption rate of plugin hybrid vehicles is high in Sweden and is rising faster than the sales of fully battery electric vehicles.Therefore, Sweden is located at level 7 in the multidimensional readiness index in societal readiness levels.

Economic Readiness Level in Sweden
In 2018, Sweden introduced a new incentive scheme called "Bonus-Malus" to encourage buyers to buy electric cars, light trucks, and buses.The government announced a SEK 60,000 (approximately USD 6998.70)purchase incentive bonus to the buyers of fully electric vehicles, and a 25% climate bonus on the vehicle's value.The government announced a 35% bonus on buying a climate-friendly vehicle for businesses.The incentive presented a maximum of a 35% difference between the new vehicle price and the similar fossil-fueled vehicle price.Six months after the car is registered, the incentive is paid straight to the owner, preventing the vehicle from being sold onward within that time frame.The bonus is decreased by SEK 833 (approximately USD 97.17) per gram of CO 2 over zero and up to 60 g/km [36].
To make the operating cost affordable, the Swedish government started supporting the development of increased charging infrastructure.Therefore, the government introduced the climate shift program in the Swedish language called "Klimatklivet".This program aims to reduce CO 2 emissions at a local level.For this purpose, the government announced granting up to 50% of the installation cost for a single charging point to the local housing associations.Moreover, electric vehicles are much more affordable than fossil-fuel-based vehicles in Sweden.The energy cost of running an electric car is SEK 2.25 (approximately USD 0.26) every 10 km, compared to SEK 12 (approximately USD 1.40) for the same distance traveled in a fossil-fuel-based vehicle.
Moreover, the maintenance cost of electric vehicles is lower than fossil-fuel-based vehicles due to fewer moving components [37].Additionally, electric vehicles are quiet and fun to drive due to their high-performance capabilities.Even though the government provides rebates on purchasing electric vehicles, the prices are still high.Buying a fully electrified vehicle is not economical because of the present lack of charging infrastructure.Therefore, Sweden is positioned at level 7 in the economy readiness levels of the multidimensional readiness index.

Discussion
The data discussed in the above disclosure is based on the factors involved in assessing the state of global readiness for the electrification of all modes of electrical transportation equipment and supporting systems.This discussion concludes that merely relying on technical analysis will not lead us toward the complete transportation system for electrification.We need other political, societal, and economic perspectives to explore, understand, and support the whole system to successfully transform the transportation system towards electrification.
As a result, additional factors such as political, societal, and economic readiness must be considered and balanced alongside the available technology to attain a high degree of diffusion of an electrical transportation system.Our research has noted that the major dimension in the public discussions of electrification has been globally focused on technology.Until all the readiness factors have been globally given due consideration, the introduction of the complete and adequate electrification of all modes of transportation equipment and their associated systems will not proceed effectively or expeditiously.From our point of view, all four dimensions of the states of readiness are complementary and thus equally important.All must be fully integrated and implemented to support the development and diffusion of transportation electrification.
To evaluate the technology, political, societal, and economic readiness levels of each country, we have used TRL, PRL, SRL, and ERL scales.Each country is positioned in the multidimensional readiness index model based on the evaluation of the readiness scales, as shown in Figure 10.
We have calculated the percentage for further graphical representations based on the multidimensional readiness index model results.Table 5 shows the status in the percent of each country's readiness level (technology, political, societal, and economic) and the position of each country (China, Norway, and Sweden) in the development of the electrification of the transportation equipment and supporting systems.
Table 5 shows that China scored 97%, followed by Norway and Sweden at 89% and 75%, respectively, in the development of transportation electrification.The calculations in Table 5 were used to plot a graph in Figure 11 to better visualize the positioning of the countries in transforming the transportation system.point of view, all four dimensions of the states of readiness are complementary and thus equally important.All must be fully integrated and implemented to support the development and diffusion of transportation electrification.

From January 2020 to August 2020, the South Korean LG Chem was the leading company in manufacturing lithium-ion batteries worldwide.Contemporary Amperex Technology Limited (CATL) and BYD are the leading Chinese battery manufacturers.CATL is ranked second with a market share of over 29%.CATL is the most significant international electric vehicle battery exporter to BMW, Honda, Hyundai, Tesla, and Volkswagen.Besides Panasonic, a Japanese battery making company, China and South Korea are leading in battery manufacturing for electric vehicles.China has a complete value chain in the electromobility industry, from the initial reception of materials through its delivery to market and everything in between.The success behind China's lead in the field of electromobility is the Chinese government's implementation power of favorable electric transportation policies and strategic positioning of EVs in upgrading the automotive industry, communication technology, and smart-city development.The Chinese central government considers it a vital national policy to promote the country's development and diffusion of electric transportation.In 2019, when the Chinese government stopped providing subsidies on EV purchases, the EV manufacturing industry reported five months of decreasing sales in the second half of 2019.Once the government revived the subsidies on EVs in 2020, EV sales sharply increased and reached 1.3 million units in 2020 compared with the 1.1 million units sold in 2019.The Chinese government provides rebates, subsidies, and tax exemptions and keeps the charging low rates for electric vehicles to promote clean electric transportation in China.Therefore, China is positioned at level 9 in technology, political, and societal readiness levels, whereas it is at level 8 in the economic readiness levels of the multidimensional readiness index.The overall score of China is 35 based on the readiness scoring scale of transportation electrification and 97% readiness in the field of transportation electrification systems, as shown in Figure 11.Table 5 shows that China scored 97%, followed by Norway and Sweden at 89% and 75%, respectively, in the development of transportation electrification.The calculations in Table 5 were used to plot a graph in Figure 11 to better visualize the positioning of the countries in transforming the transportation system.China is a leading country in electromobility technology, industry, and market, according to the Electric Vehicle Index 2021.China is at the forefront of transitioning from fossil fuels to electric vehicles.Chinese society is rapidly moving towards BEVs.China is leading in manufacturing pure battery electric vehicles and batteries, and South Korea ranked first in innovation, according to Bloomberg [38].Of the top ten fully battery electric vehicle manufacturers, nine are Chinese companies, and the other one, Tesla, is a USA brand also manufactured in China.By the end of June 2021, 1.947 million charging piles and 716 battery swapping stations were available for charging electric vehicles in China.
One key system for electrified road transportation is batteries.Asian companies are leading the electric vehicle battery industry.They are expanding their manufacturing capacity in Europe and the USA to secure profitable contracts from international electromobility manufacturers.LG Chem and Samsung SDI are the largest South Korean battery manufacturing companies.
From January 2020 to August 2020, the South Korean LG Chem was the leading company in manufacturing lithium-ion batteries worldwide.Contemporary Amperex Technology Limited (CATL) and BYD are the leading Chinese battery manufacturers.CATL is Norway does not manufacture electric vehicles or electric vehicle batteries, but it imports from other countries such as the USA, South Korea, Japan, and China.NIO Norway (Chinese BEV supplier) has also started its sales in 2021, and several other Chinese brands, such as XPeng, LiAuto, B.Y.D., and others, are moving to Europe.Norway is a small but geographically long country, and people need to travel long distances for their daily life activities.Almost 96% of electric vehicle owners have access to a charging station in their homes or apartments.However, long-distance travelers or tourists with their electric vehicles need public charging stations, which presently lack in number and distribution.The government has started funding for constructing at least two multi-standard fastcharging stations at every 50 km along all of Norway's major highways.Despite the lack of electromobility technology, Norwegian government policies are the game changers, positioning Norway as the global leader in EV adoption.The sales of electric vehicles are rapidly increasing over fossil-fueled vehicles in Norway, with a staggering 54% of new cars sold in 2020 being powered by electricity.In 2020, December was the best month, with sales reaching 66.7% of electric vehicles.The Norwegian government aims to sell 100% electric cars by 2025.The cost of purchasing and operating fully electric vehicles is more affordable than fossil-fueled or hybrid vehicles.Even though Norway is an oil-producing country, the government has imposed high purchase and CO 2 taxes on fossil-fueled vehicles; in contrast, electric vehicles are exempted from purchase, VAT, and road tolling taxes, and are eligible for free parking.The Norwegian government's dedication to introducing electric transportation in society maintains Norway's position as a successful global leader in implementing a clean transportation system.Therefore, Norway is positioned at level 9 in politics, societal, and economic readiness levels and 5 in technology readiness levels in the multidimensional readiness index.The overall score of Norway is 32 based on the readiness scoring scale and 89% readiness in the field of transportation electrification systems, as shown in Figure 11.
Sweden is one of the top innovative countries in the world and the number one in the EU.According to the Bloomberg Innovation Index 2021, Sweden is ranked fifth among the innovative countries worldwide, while in the EU Innovation Scoreboard, it is ranked first.However, Sweden still lags behind in electromobility despite manufacturing its electric vehicles in Belgium and China.Swedish Volvo manufactures its prestigious electric vehicle (Polestar) in China.The new Volvo XC-40 launched in 2021 is manufactured in Belgium and China.However, Sweden does not have its own battery manufacturer.Thus, Swedish EV manufacturers purchase batteries mainly from Asia, Europe, and the USA.In the majority, Volvo manufactures hybrid vehicles rather than fully electric ones.Scania and Volvo launched their first electric trucks in 2020/2021.In Sweden, several charging technologies are in the testing phase, such as electric roads (conductive and inductive), and the government is considering looking into further battery swapping solutions.Static cable-based charging is regarded as a relatively mature technology that is primarily used to charge passenger vehicles.However, static charging faces a standard technical problem: there is no standardized charging plug.Buying electric vehicles and operational costs are still expensive in Sweden despite government rebates and the exemption of taxes.Therefore, Sweden is positioned at level 7 in politics, societal, and economic readiness levels and 6 in technology readiness levels in the multidimensional readiness index.The overall score of Sweden is 27 based on the readiness scoring scale of transportation electrification and 75% readiness in transportation electrification systems, as shown in Figure 11.

Conclusions
The development and implementation of the electrification of the transportation system depends on society's readiness to pursue the development, adoption, and diffusion of electrified transportation.Technology is a crucial foundation for electrification and must be viewed and understood when commercialization and value creation to business, people, and benefits to the entire society are also considered.Technology cannot be diffused in society and create value without a well-developed interplay of industry, academia, politics, economic institutions, and policy systems pushing and supporting economic and policy tools and regulatory tools.
Our analysis shows that only focusing on technology will not lead us to the successful complete implementation of the electrification of the transportation system.Therefore, to achieve a high level of the diffusion of electric transportation systems, it is important to balance the political dimension, focusing on government support to develop and implement policies that promote the electrification of the transportation system.The other factors involved are the degree to which societal readiness to switch from fossil fuel to electric vehicles has been enrolled.The fourth is the economic readiness in which subsidiaries have met the transformation financial needs to compensate for any price difference.The motivation of people to hold out until the scale of the costs involved in the adaption and adaption of the new technology meets or betters the costs incurred for old fossil-based technology must be diligently fostered.
Our analysis shows that political readiness is one of the most crucial dimensions of the readiness to support the transformation to electric transportation, followed by societal and economic readiness.The political readiness is demonstrated in the political willingness to reshape regulatory aspects, introduce and change subsidiaries, use public funding for R&D, and build the charging infrastructure.Political readiness can be observed on the rhetorical level and on the action level.Our focus is on the real action level of politics and policymaking.
We view the electrification of the transportation system from a complex system perspective.The electrification of transportation is not an isolated system that can be handled independently as a single technological entity.This system is interconnected with and dependent on the other subsystems, such as energy production, electricity distribution in the grid system, and storage that form the whole technical system embedded in each country's political, social, and economic context.Therefore, a system approach is required to see the electrification of the transportation system from a holistic perspective.Other subsystems need to be considered besides technology alone, i.e., politics, society, and the economy.To help achieve this understanding, we have introduced the multidimensional readiness index model based on those key dimensions.
The depth of penetration of electrified transportation systems in society is still very much premature and in the early phases of diffusion; thus, it still mainly relies on the economic policies developed and announced by the government, including the economics of new infrastructure, the identification of solutions to electric public transportation problems, providing rebates for EVs and tax exemptions, and imposing high taxes on CO 2 emission vehicles.Government commitment is the key to success for the rapid transition from fossil fuels to electric transportation.China's success in leading the world in the electrification of the transportation system is primarily due to its strong government and practical institutional actions.
Norway is the second leading country in the diffusion and adoption of electric vehicles because of its favorable government policies for transportation electrification, even though Norway itself does not manufacture electric vehicles and charging equipment.
Sweden is still lagging behind China and Norway, even though Sweden is one of the most prominent countries in innovation globally and has built its own luxury hybrid electric vehicles.However, due to the Swedish government not taking rapid action, it has been held back in the electrification of the transportation system.Volvo Cars manufactures its electric cars in China.Scania Trucks and Volvo have started to market their first generation of electric trucks.Volvo has declared strategic collaboration with Daimler regarding hydrogen technology for ICE vehicles, while Scania officially chooses battery-based heavy trucks.
