Keywords: Electric vehicle, battery, solar energy, energy efficiency, system integration, power density, PV arrays


In this paper, it has been theoretically and conceptually examined the technical, design, and economic viability of using Photovoltaic (PV) technology in combination with battery operated Electric vehicle (EV) in Public Bus sector in India, where solar energy is readily available. The study is further analyzed to propose the utilization and economics of “PV integrated EV” technology along with solar and battery integrated solution. The available battery chemistries are studied, and the best suited solution based on parameters such as cost, weight NMC battery is chosen. Finally, the number of solar panel and battery requirement is calculated based on the power consumption of the vehicle and concluded.
