Abstract: A close look at EV chargers and its subsystems in the Indian context”: With adoption of EVs, EV chargers find a very important place in the ecosystem. There are various types of EV chargers, each catering to a unique segment of vehicles. This presentation will try to explain the how and whys of the various charging systems in the market. It would strive to explain the architectures of the charging stations, the major building blocks and commonly adopted methodologies for designing a charger. It would also touch areas like V2G energy transfer, second life of EV batteries and distributed energy storage.
