With the rapid promotion of electric vehicles with multiple utilities such as energy conservation and emission reduction, in the area of intelligent charging and exchanging for electric service, the government, related parties of upstream and downstream industries, and users have increasingly urgent demand for information sharing and interactive participation. Based on the status of this demand, this paper proposes to build an idea of electric vehicles public service interactive platform. Through the overall objective, program, architecture design of interactive platform and analysis of related key technologies, it designs seven functional clusters for interactive platform. It gives data models of interactive platform and researches its service interfaces and processes. Finally, the paper describes website and mobile APP and the significance of the development of electric vehicle charging and exchanging industry. Through the research of electric vehicle’s public service and interactive platform, it provides theoretical basis and discovery application for further development of electric vehicle’s public service area, which possesses very important research and application value.
