Abstract: Aiming at the problem of balancing the layout of electric vehicle charging facilities with the demand of electric vehicle users,an electric vehicle charging facility layout optimization method based on multi-source data is proposed. Firstly,the two-layer layout optimization model is set up for EV charging stations based on multi-source data such as POI（Point of interesting）location,location and demand preference of users when they generate charging demand. The upper model takes the total social cost as the objective function to optimize the location and capacity of EV charging stations;the lower model builds the user’s best choice model based on three indexes,i.e. addressing distance,addressing time and congestion level;Then,the two-layer planning model is solved by genetic algorithm to obtain the layout optimization scheme of EV charging stations. Finally,the feasibility of the proposed method is illustrated by example verification.
