Electric vehicle (EV) chargers are highly nonlinear power system load. They present a potential problem to power systems in the forms of excessive harmonic currents and poor power factor. Thus it is important to analyze the effect of EV chargers on power system harmonic current and then to take some measures to improve the loading factor of power systems and acquire better power quality. In this paper, we have set up individual EV charger model on the base of analyze of actual data from a commercial-available EV charge and battery. By computer calculation and simulation we analyzed harmonic current of individual EV charger and also have predicted the harmonic currents produced by a group of EV chargers.
