Solar PV Tied Electric Vehicle Charging System Using Bidirectional DC-DC Converter

Abstract

Renewable energy-based battery charging systems for Electric Vehicles (EV) have seen surge in automotive research in last few years. Solar PV-fed EVs are thoroughly examined in this research. Among the many benefits of using batteries to store energy in ground vehicles include zero emissions, load levelling, excellent transient functioning, and ability to recover energy while braking. To meet these criteria, bidirectional DC-DC converter is needed to connect PV to battery's dc-link. A PV-powered electric vehicle must be able to operate in two distinct modes: charging and discharging. Maximum Power Point Tracking (MPPT) technique is utilized in this study to harvest most power by solar PV. In addition, DC-DC converter with bidirectional output requires closed-loop control circuit which is proposed in this paper. MATLAB simulations are used to confirm system's efficacy.
