The electric vehicle circular charging device is a kind of large, high-power, DC, box charging equipment, which has the characteristics of power sharing and flexible charging. In order to make the circular charging device work and operate normally, a remote mobile monitoring and fault diagnosis system is designed based on cloud platform. The system is composed of server and mobile terminal. The server is developed based on Web Service platform, providing large data interaction for mobile terminals. The mobile terminal is based on the Android platform to design the mobile monitoring function for the charging pile and to handle the fault. The analysis and diagnosis method based on fault tree and fault processing flow of charging equipment is given in detail.
