Abstract The promotion and popularization of the electric vehicles will lead to the large demand for high-power charging device, and the modern power electronic technique of charger is highly nonlinear electrical equipment. The impacts of a large number of charging station working on the grid cannot be ignored. In present study, considering the reasonable charge technology and charge scale for the large number of the electric vehicles, the models of single charger and charge station are built to analyze the impacts of the power quality. The factors of the harmonic current ratio, the current total harmonic distortion and the power factor varied with the charging power and the number of the chargers are discussed and analyzed. The simulation results show that the harmonic current ratio decreases with the increase of the number of chargers in the high power charging, and it changes relatively flat in the low power charging. Furthermore, the trend of the total harmonic distortion decreased with the increase of the charging power and the number of chargers, and the variation of power factor is determined by the coupling mechanism of the charging power and the number of the chargers.

Key words： Electric vehicle charging station rectifier harmonic analysis power factor
