PV-based off-board electric vehicle battery charger using BIDC

Abstract

In recent years, the use of renewable energy sources is increasing drastically in several sectors, which leads toits role in the automobile industry to charge electric vehicle (EV) batteries. In this paper, a photovoltaic (PV) array-fedoff-board battery charging system using a bidirectional interleaved DC-DC converter (BIDC) is proposed for light-weightEVs. This off-board charging system is capable of operating in dual mode, thereby supplying power to the EV batteryfrom the PV array in standstill conditions and driving the DC load by the EV battery during running conditions. Thisdual mode operation is accomplished by the use of a three-phase BIDC. The model of the proposed system is simulated inMATLAB/Simulink software while a hardware prototype of 250 W is fabricated and tested in the laboratory. Simulationand experimental results are furnished in this paper.
