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

Summary
Ever-growing stress on fossil fuels has led to the depletion of nonrenewable sources of energy and damaged the environment. Multiport converters (MPCs) are popular in hybrid electric vehicles (HEVs) due to their capability of interfacing power sources and energy storage elements like PV arrays, ultracapacitors, supercapacitors, fuel cells, and batteries with the loads in EVs like the motor, lights, power windows and doors, radios, amplifiers, and mobile phone chargers. These multiport converters are classified as isolated and nonisolated converters. This helps to charge the EV battery from the PV array in a forward direction and discharge the EV battery in a reverse direction to drive the DC load
