Abstract: |
This paper describes an electric vehicle battery charging mechanism with solar PV array based multipurpose EV charger. Multipurpose EV charger consists of two converters, one is bidirectional DC-DC converter (BDDC) and other is voltage source converter (VSC). The operation of the EV battery charger is managed in such a way that it is either supplied by PV power or by a grid. Vehicle to the grid (V2G) operation is implemented for improving the stability of the grid during peak load hours and vehicle to home (V2H) is also enabled during islanding mode of operation. For regulating the DC-link voltage from the bidirectional battery converter, a PI control mechanism was provided to this system. The bidirectional DC-DC converter works in buck mode during the charging time of the EV battery and works in boost mode during the discharging time. The charging system operates as an active power filter using voltage source converter (VSC) and the total harmonic distortion (THD) of the grid current lies within the IEEE 519 standard. The various modes of operations are simulated and tested by using MATLAB/Simulink. |
