Abstract:This paper discusses a way to solve the problems of repeated investment and waste of resources in the process of site selection of electric vehicle charging station, which can meet the charging needs of electric vehicle users on the one hand, and improve their economic benefits on the other hand. Based on the operation data of new energy vehicles and charging data of charging piles collected by a company"s vehicle-pile integrated platform, combined with the actual investment and construction needs of the company, we take the minimum turnaround period as the objective function and establish the location planning model of charging stations, after fully considering the economic income and various investment costs of charging stations. To verify the correctness of the model, we use the differential algorithm to solve the model in 15 pre-selected sites, and get the minimum turnaround period of each site and the number of charging piles needed. According to the results of the model, it is found that the station 6 is the best one based on the shortest period of recovering the investment cost, and the station 1 is the best one based on the average annual income, which is in accordance with the actual work experience.
