The nonlinear load of electric vehicle AC charging pile brings harmonic pollution to the power system, which seriously affects the safe and stable operation of the power system. In this paper, the AC charging pile of an electric vehicle is taken as the research object, and the system simulation and harmonic analysis are carried out. And APF is used to compensate and suppress the harmonic of the simulation model of electric vehicle charging. The simulation results show that the charger mainly increases the 5th and 7th harmonics to the power grid. After adding APF to the power grid side, the harmonics of the power grid side are suppressed, and the influence of the charging pile on the DC power grid is greatly reduced.
