| Large-scale electric vehicles access to the distribution network will cause harmonics on the grid side. Therefore, it is necessary to study the influencing factors of the harmonics of the charging station. Firstly, the theoretical analysis of the harmonic mechanism of the charger is carried out. Secondly, the influence of chargers with different power levels on the harmonics of the charging station is studied. Then, the number of chargers, the SOC of the power battery and the harmonics are further studied. In the end, a calculation method of current total harmonic distortion rate (THDi) considering the timing characteristics of electric vehicles is proposed. It is verified that the calculation method has high accuracy and can meet the needs of engineering practice. The THDi of the taxi charging station was calculated by the proposed method, and the influence of the timing characteristics of the electric vehicle on the harmonics of the charging station was studied.
