The charging of electric vehicles in residential area, such as electric bicycle, electric slow vehicle, electric car, etc. has the problems that charging mode and payment means are single, charging infrastructure lacks of effective operation management and cannot be shared, etc. To solve these problems, this paper puts forward an idea of establishing charging service platform for electric vehicles in residential area. The overall target, plan, architecture and key technologies of electric vehicle charging service platform in residential area are analyzed and discussed, and the technology solutions of electric vehicle charging service platform in residential area are proposed. Through the demonstration and application of website and mobile APP of electric vehicle charging service platform in residential area, the problems of electric vehicle charging in residential area are solved. The demonstrative application shows that electric vehicle charging service platform scheme in residential area effectively solves the charging problems, providing a theoretical basis for business development of electric vehicle charging service in residential area. It has important research and application value. This work is supported by National Key Research and Development Program of China (No. 2016YFB0101800).
