Design and Simulation of Low Power Charging Station for Electric Vehicle

The depletion of fossil fuels and increased pollution has led to the invention of Electric Vehicles (EV). An Electric Vehicle requires an onboard charger (OBC) to charge the battery for its propulsion. The objective of this paper is to present the design and simulation of unidirectional onboard charger that can charge the traction battery through the single phase AC power grid. Here, the OBC consists of an AC-DC converter and Buck type DC-DC converter to regulate the charging voltage and charging Current of the battery. A 210W charger is considered for the design with a lead- acid battery of nominal voltage of 48 V, 35 Ah, and simulation results are obtained in MATLAB/Simulink.
