Battery Management System Using Sepic Converter With Pv ased Ev

EVs have been continuously evolving energy-efficient alternatives to vehicles powered by combustion engines during the last decade. However, boosting the battery efficiency in EVs presents a number of obstacles. Range anxiety is an unresolved issue due to the limited range of single charge. The EV suffers from relatively short range and long charging times and consequently has not become an acceptable solution to the automotive consumer. This paper mainly focuses on improving the battery efficiency of EV to meet out the requirements for long range of transportation with less charging time. The most efficient types of wireless power transfer method called magnetic inductive coupling with less losses is performed. Instead of using repeated coils to transfer power to long distance, a new system is implemented by converting nominal frequency into high frequency resulting in producing more flux which transfers more power to receiving coil. The proposed system can transfer power even it is subjected to any obstacle. To make the journey green, an on-board solar PV roof is considered as another charging source in regards with improving efficiency of the battery. The battery management system is achieved by using modified SEPIC converter to control different voltage level from wireless power transmission and on-board PV system.
