The scarcity of fossil fuel and the increased pollution leads the use of Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV) instead of conventional Internal Combustion (IC) engine vehicles. A solar PV is integrating with utility grid to supply the battery used for vehicle. In this paper, PV- grid load sharing algorithm was added to the utility grid operation control to compensate fluctuation of PV output, with its main purpose is to deliver constant power to the battery. Here dual loop control algorithm is implemented to the phase shift full bridge converter such that the sum of load current is summation of PV and grid current. In this research, the total power output from the system is limited to 3kW. For example, if PV produced 1kW, then PSFB closed loop controller drove the utility grid to produce 2kW. A MPPT algorithm is implemented to the solar PV so that maximum power is delivering the load. The objective of the project work is to design a charger that can charge the battery with the use of renewable energy adding only compensation through grid. The grid is connected with the battery through Interleaved Boost PFC converter at the first stage to obtain unity power factor with low Total Harmonic Distortion (THD) and a DC-DC phase shift full bridge converter to regulate the charging voltage and current of the battery. The battery is a Lead-acid battery with a nominal voltage of 120 V, and is charged from cut-off voltage of 80V to fully charged voltage of 124V. The function of the second stage DC-DC converter is to charge the battery in a Constant Current and Constant Voltage manner. A 3KW prototype of battery charger is designed and simulated in MATLAB/Simulink. The power factor obtained at full load is 0.999 with a THD of 2.08%.
