Research on electric vehicle fast charging station billing and settlement system

Abstract

In order to meet the trend of increasing scale and more complexly layout of electric vehicle(EV) fast charging station(FCS), as well as the development of urban intelligent city, this paper studied on use mobile Internet and mobile terminal to realize the intelligent billing and settlement system of EV FCS, which provided a integrated charging billing model based on time-of-use price, proposed a solution to achieve system that can scan identification through vehicle QR code, guide the charging vehicle orderly parking by APP, start charging process, and realized no card payment by the mobile terminal. At last, this paper gave experimental result to verify time-of-use price is the important influence factor to integrated charging fee, and the billing model which adopted optimized peak-valley segmentation method can instruct the customer to charge economically, a lot of users can save the cost of travel. The system can enhance the customer satisfaction and will help to improve the operational efficiency and service capability of EV FCS.
