One of the main factors propelling the growth of the automotive industry in the last ten years has been the advancement of electric cars (EV). The infrastructure for battery charging is one of the key elements influencing the development of electric vehicles. A higher energy consumption is required of the system when the battery of an electric car is charged via the power grid.Given this, the authors of this research propose a photovoltaic (PV) array-based controller-based off-board EV battery charging system. Together with the PV array, a secondary battery bank is used to guarantee that the electric vehicle's battery is constantly charged.The sepic converter and the three-phase bidirectional DC-DC converter in the recommended system allow the EV battery to be charged at any time of day or night.During the hottest part of the day, both the EV battery and the backup battery are charged. At night or on overcast days, the backup battery assists in recharging the EV battery. The outcomes of a Simulink simulation conducted inside MATLAB using the recommended charge system are shown.
