This paper proposes to design and simulate an efficient battery charging facility for electric vehicles using a stand-alone PV panel. The power conversion stage is designed to get the required voltage level to charge the battery pack. The conversion stage uses two controllers. One controller tracks the maximum power from the PV array and the other regulates the DC voltage for charging the battery pack. Maximum power from the PV array is extracted using the classical method, perturb and observe. A charge controller regulates the voltage level required for charging and discharging battery the pack with a voltage mode control strategy. A closed-loop PID controller with Ziegler–Nichols tuning technique is employed to obtain the control signal. The duty ratio obtained by the PWM and driver circuit is responsible for controlling power switches in the power converters. The regulated voltage delivered by the charge controller is utilized to charge the battery pack. The battery parameters are obtained and analyzed for the charging and discharging cycle.
