Control and Design of an Electric Vehicle Battery Charger Utilizing Solar PV System

The development of electric vehicles (EVs) has resulted in an increase in the automotive sector over the past years. The battery charging mechanism is vital to the progress of EVs. However, EV battery charging from the grid raises the system’s load demand and ultimately rises energy prices for EV owners, necessitating the usage of alternative energy sources. Renewable energy sources(RES) can be utilized to charge an EV battery due to their unlimited availability and pollution-free. Solar PV is one of the easily accessible RES that is promising and can be used to power EV batteries. If solar PV is used in conjunction with a dc-dc converter, backup battery bank, and three-phase bidirectional converter, the EV battery will always be charged regardless of solar irradiation. So,in this study, a solar PV array with a modified sepic dc-dc converter for high efficiency and a lithium-ion battery because it is widely used are chosen. The suggested method has the ability to charge the EV battery during both sunny and cloudy periods.
