Modelling and Control of SEPIC and BIDC Converter Based off-Board EV Battery Charger using PV Array

Abstract

Recent years have seen a dramatic increase in the usage of renewable energy sources in a variety of industries, including the automotive sector where it plays a role in charging the batteries of electric vehicles (EVs). Here, we present a method for lightweight EVs that uses a solar energy power conversion with SEPIC and bidirectional interleaved DC-DC converter (BIDC) to charge their batteries from the grid instead of on-board. The suggested technology can recharge the electric vehicle's battery throughout daylight and nighttime hours. The EV battery and the backup battery both get charged during peak sunlight hours, and the backup battery helps charge the EV battery when the sun isn't out. In order to test the effectiveness of the proposed charging method, a simulation was run in the MATLAB software using the Simulink application.
