Review on Green Energy Alternatives for Electric Vehicle Charging

The transportation industry has undergone a significant transformation in recent years, with a substantial transition towards the adoption of environmentally friendly electric vehicles. Electric vehicles provide numerous benefits over conventional vehicles. A greater number of charging stations will increase the adoption of EVs since range anxiety is the key limitation in their growth. EV charging stations should be safe, reliable, efficient, and fast. Besides the conventional power grid, renewable energy sources can also be harnessed for charging electric vehicles, alleviating the current grid's stress. A thorough overview of EV charging techniques, standards, EV charging station architectures, and various power electronic converters for EV charging stations is presented in this paper. Finally, issues with smart electric vehicle charging and grid integration are summarized, along with potential future developments. This paper explores the compelling concept of charging EVs using green energy sources like solar, wind, and biogas.
