In the Summer and Fall 2015, the authors studied the business case for investing in a Direct Current Fast Charging (DCFC) infrastructure in Canada for the benefit of the Canadian Council of Ministers of the Environment. This paper summarizes our rese...
Driving cycles are used in various aspects of vehicle development and for the homologation of new vehicles. The character and duration of a cycle have a huge impact on the energy consumption for longitudinal dynamics and comfort functions. Current dr...
The paper deals with the description of a low voltage, two-battery pack, two-motor, two-axle powertrain configuration for a full performance compact electric car. It gives an analytical method for selecting the two different drives for front and rear...
Although an electric snowmobile can be constructed, there are several technical challenges to make it viable for end-users. The energy requirements are extremely variable and depend on the weather conditions. Both temperature and snow conditions add...
CALSTART researched and analyzed the opportunities and challenges faced by the medium and heavyduty electric truck market. E-Trucks & Buses present unique challenges and opportunities compared to light-duty EVs. In particular, current utility rat...
The Plug-In Hybrid Medium-Duty Truck Demonstration and Evaluation Program was sponsored by the United States Department of Energy (DOE) using American Recovery and Reinvestment Act of 2009 (ARRA) funding as well as the South Coast Air Quality Managem...
In this paper, the authors present the challenges & opportunities behind the engineering of a fully-electric mobile railcar mover. We present how building the right toolbox of simulation software, proper analysis and understanding of the duty cyc...
Medium and heavy duty (MD and HD respectively) vehicles are responsible for 26 percent of the total U.S. transportation petroleum consumption [1]. Hydrogen fuel cells have demonstrated value as part of a portfolio of strategies for reducing petroleum...
Designed by students and faculty at Western Washington University’s Vehicle Research Institute, the Lyn Okse (“Lightning Ox”) electric vehicle targets the needs of the campus Facilities Management organization’s grounds crews, maintenance and skilled...
In this contribution, additional degrees of freedom resulting from an additional motor in the front wheel (all-wheel driven motorbike) are used within newly developed methods for enhancing safety and energy efficiency. All algorithms have been develo...
This paper presents a model aiming at describing the influence of an additional mass on an urban vehicle. The impact of an in-wheel motor on the road holding performances and vehicle comfortableness, for which criteria have been defined, has been stu...
When putting electric buses into practice in mass transit systems, the vehicle state management becomes a vital factor in the realization of a stable commercial operation. Aiming at achieving a sound bus operation, we installed a vehicle monitoring s...
Meeting the worldwide energy demand for the present and future transportation systems with the least impact on the environment is a big challenge. In the i-NEXT (Innovation for greeN Energy and eXchange in Transportation) project a Fuel Cell Hybrid E...
City buses with hybrid and battery electric power trains as well as conventional reference vehicles have been examined using a standardized methodology, mainly focusing on exhaust and noise emissions, overall energy efficiency and operational availab...
This paper examines the possibility of establishing an electric car-sharing program in New York, of the type that the French firm Bolloré articulated in France (Autolib) and in Indianapolis (Blue-Indy). It examines the current role of electric vehicl...
This paper presents a systematic approach for optimal selection of race discipline and race format to develop a battery powered racing vehicle that is competitive with internal combustion vehicles. The main limitation for battery powered vehicles i...
Electrification of non-road mobile machinery (NRMM) is a growing trend. This paper highlights the potential of electric and hybrid powertrains in different NRMM sectors and elaborates the factors that may hinder the development. The NRMM sectors, the...
In this paper a novel concept of modular swift-shift multi-speed transmission with double dual clutches is proposed, with its architecture, simulation and control strategies discussed in detail. Due to its modularity, the desired number of gear ratio...
In this paper, a simple but innovative algorithm is developed to effectively reduce peak-to-average power ratio for electric vehicles powered by battery pack (BP) alone under real-life load fluctuation. A convertersupercapacitor pack (SP) coupled Hyb...
The present paper outlines an analysis of the energy consumption of a light commercial vehicle that is powered purely electrically by an induction machine. The question was to what extent energy consumption is impacted by two defined aspects: On the...
The energy consumption of battery electric vehicles (BEVs) depends on a number of factors, such as vehicle characteristics, driving behavior, route information, traffic states and weather conditions. The variance of these factors and the correlation...
The introduction of electric vehicles (EV) is considered by many as an effective solution to alleviate petroleum dependency; however, the number of EVs in the current market remains scarce despite of its potential benefits. Many studies have been con...
The field of fast charging is diverse. Many solutions use dedicated additional costly components for each charging type. To push the E-Mobility market, a new system for charging is proposed comprising of E-Machine, Inverter and Boost DC/DC converter...
The impact of mileage accumulation and fast charging on driving range and battery energy of a light-duty battery electric vehicle (BEV), commercially available in North America, is being investigated. Two identical model BEVs are undergoing mileage a...
In-Wheel Motor (IWM) have been proposed to increase an efficiency and controllability of electric vehicle (EV). However, a risk of disconnection of power lines have been considered as a fundamental problem of IWM. Therefore, we proposed Wireless In-W...
For hybrid electric vehicle, it is necessary to control power distribution among multiple power sources to improve fuel economy performance of vehicle. In this paper, power management strategy of hybrid electric vehicle using Dynamic programming is s...
Are electric vehicles capable of long distance trips? Yes, but with major sacrifice: either recharge several times en route, with a trip which takes about twice the time of an ICE vehicle, or make a significant capital investment in a large battery a...
The Electric Power Research Institute (EPRI) and its project partners have developed some of the highest resolution and most complete Light- and Medium-Duty Plug-in Hybrid Electric Vehicle Truck operational data for Odyne and Via trucks. This data wa...
The U.S. Department of Energy (DOE) Vehicle Technologies Program (VTP) is developing more energyefficient and environmentally friendly highway transportation technologies that will enable America to use less petroleum. The VTP includes studies of the...
