Abstract Charging station load calculation method and its influencing factors are the research focus of charging station construction. Many literatures have drawn the conclusion that it is only suitable for charging station planning and power grid load regulation through simulation experiments and the establishment of modern calculation models. Although the simplified engineering calculation method is given in some literatures, the calculation results deviate greatly from the actual operation data due to the lack of actual operation data analysis. In this paper, the demand coefficient method is used to calculate the main load of charger in charging station. Four variables affecting the demand coefficient are decomposed. Then, around these four variables, the factors affecting the calculation of charger load are analyzed, and it is concluded that the charger load coefficient Ks and simultaneous operation coefficient Kt are the two main factors that directly affect the demand coefficient. Finally, the operation data of the existing charging stations are decomposed and analyzed, and the operation experience values of the load coefficient Ks and simultaneous operation coefficient Kt of the charger are analyzed emphatically. The demand coefficient values of the charging stations suitable for public charging stations and bus special charging stations are obtained.
