The current planning methods of electric vehicle (EV) charging stations fail to effectively coordinate the benefits of both operators and users

and the cumulative effects of the timing traffic on waiting time lack detailed analysis. Hence a more accurate method for planning EV charging stations on the expressway is proposed. Firstly

a mathematical model is built for maximizing the comprehensive benefits of the stations’ operators

investors and EV travelers. Secondly

a dynamic simulation method of EV flow and travelers’ charging selection is proposed. Afterwards

the model is solved by using chaos particle swarm optimization. The effectiveness and practicality of the proposed method are verified by the case study.This work is supported by National Natural Science Foundation of China (No. 51477116).
