This analysis suggests that the current rise in the automotive sector is mostly due to the renewable energy-based electric vehicle battery charging technology. Due to the intermittent nature of renewable energy sources, grid-connected renewable energy systems are used to charge the batteries of electric vehicles. As a result, this article suggests a grid-connected PV system-based electric vehicle battery charger. The suggested system uses bidirectional ac-dc converters and dc-dc converters to continually charge the EV battery regardless of solar radiation. With the aid of the suggested bidirectional design in the charging system, Sepic converter is selected for dc-dc converters and Line commutated converter is employed as a bidirectional ac-dc converter. During sunshine hours, PV array power generated is used to charge the EV battery alone and during peak sunshine hours, apart from charging of EV battery, the excess PV array power is fed to the single phase utility grid. During low and non sunshine hours, the EV battery charging was supported by the utility grid through bidirectional ac-dc converter. The proposed electric vehicle battery charger is simulated in the MATLAB/Simulink environment and the dynamic response of the system was studied and its results are furnished in this paper.
