A study on trends and developments in electric vehicle charging technologies

The involvement of electric vehicles (EVs) is increasing over the past few years due to several factors including the increasing emission of carbon dioxide (CO2), depletion of fossil fuels, and promotion of renewable deployment. The growth of charging stations is essential to support the transition of conventional vehicles to electric vehicles. This research paper reviews the current and future trends in EV battery charging methodologies and the roadmap for EV adoption in India. The various conventional and advanced battery charging methods and power topologies are discussed based on their mode of operation and comparative analysis. The various levels of EV charging stations are reviewed based on their charging location, charging time, type of connectors used, architecture portfolio, and comparative performance analysis of different power converters used in EV chargers. Furthermore, advanced charging architectures for electric vehicles are discussed intensely, including fast charging, smart charging, wireless charging, and battery swapping and this paper emphasizes the use of integrated renewable energy (RE) with EV charging architecture and optimized energy management algorithms to mitigate the uncertainties caused by transmission power grids. Finally, this paper concludes with the future roadmap for EV adoption in India and put forth various research roadmaps for power electronics-based solutions related to RE integration, energy storage, and smart grid technologies.
