Special Issue Information

Dear Colleagues,

The ongoing transition towards sustainable transportation has placed electric vehicles (EVs) at the forefront of automotive innovation. Understanding and optimizing the energy consumption and efficiency of these vehicles is crucial for maximizing their range, minimizing operating costs, and reducing their environmental impact. This involves addressing complex challenges related to battery technology, powertrain design, energy management strategies, and real-world driving conditions. The increasing adoption of EVs, driven by environmental concerns and advancements in battery technology, necessitates a comprehensive analysis of their energy performance across diverse operational scenarios. This analysis is essential for developing more efficient vehicles, improving charging infrastructure, and informing policy decisions related to sustainable transportation.

This Special Issue aims to present and disseminate the latest research and developments related to the analysis, modeling, optimization, and real-world assessment of energy consumption and energy efficiency in electric vehicles. It seeks to provide a platform for researchers, engineers, and industry professionals to share their insights and contribute to the advancement of EV technology.

Topics of interest for publication include, but are not limited to, the following:

  • Energy consumption modeling and simulation, including driving cycle analysis, vehicle dynamics, and environmental factors.
  • Real-world energy consumption analysis based on on-road testing and data collection.
  • Impact of driving behavior, traffic conditions, and weather on EV energy consumption.
  • Powertrain efficiency, including electric motor design, power electronics, and transmission systems.
  • Optimization of energy management strategies, including regenerative braking, thermal management, and auxiliary systems.
  • Innovative technologies for improving EV energy efficiency, such as lightweight materials, advanced control algorithms, and novel powertrain architectures.
  • Battery performance and management systems, including battery aging, thermal management, and state-of-charge/state-of-health estimation.
  • Charging infrastructure and its impact on energy efficiency.
  • Impact of smart grid integration and vehicle-to-grid (V2G) technologies on energy consumption.

This paper presents a simulation framework for evaluating power flow, energy efficiency, thermal behavior, and energy consumption in electric vehicles (EVs) under standardized driving conditions. A detailed Simulink model is developed, integrating a lithium-ion battery, inverter, permanent magnet synchronous motor (PMSM), gearbox, and a field-oriented control strategy with PI-based speed and current regulation. The framework is applied to four standard driving cycles—UDDS, HWFET, WLTP, and NEDC—to assess system performance under varied load conditions. The UDDS cycle imposes the highest thermal loads, with temperature rises of 76.5 °C (motor) and 52.0 °C (inverter). The HWFET cycle yields the highest energy efficiency, with PMSM efficiency reaching 92% and minimal SOC depletion (15%) due to its steady-speed profile. The WLTP cycle shows wide power fluctuations (−30–19.3 kW), and a motor temperature rise of 73.6 °C. The NEDC results indicate a thermal increase of 75.1 °C. Model results show good agreement with published benchmarks, with deviations generally below 5%, validating the framework’s accuracy. These findings underscore the importance of cycle-sensitive analysis in optimizing energy use and thermal management in EV powertrain design. Full article

Regenerative braking systems (RBS enhance energy efficiency and range in electric vehicles (EVs) by recovering kinetic energy during braking for storage in batteries or alternative systems. This literature review examines RBS advancements from 2005 to 2024, focusing on system design, control strategies, energy storage technologies, and the impact of external and kinematic factors on recovery efficiency. Based on a systematic analysis of 89 peer-reviewed articles from Scopus, it highlights a shift from basic PID controllers to advanced predictive algorithms like Model Predictive Control (MPC) and machine learning approaches. Technologies such as brake-by-wire and in-wheel motors improve safety and stability, with the latter excelling in all-wheel-drive setups over single-axle configurations. Hybrid Energy Storage Systems (HESS), combining batteries with supercapacitors or kinetic accumulators, address power peak demands, though cost and complexity limit scalability. Challenges include high computational requirements, component reliability in harsh conditions, and lack of standardized testing. Research gaps involve long-term degradation, autonomous vehicle integration, and driver behavior effects. Future work should explore cost-effective HESS, robust predictive controls for autonomous EVs, and standardized frameworks to enhance RBS performance and support sustainable transportation.
