The invention relates to a charging information management platform of an electric vehicle and a charging control method of a charging device. A data collector is installed in the charging device of the individual car owner, and when other users need to charge, the charging application is inputted through the data collector, and the information management platform receives the charging applicationinformation from the data collector, verifies that the user account information is valid, and then a start-up charging instruction is sent. After the user completes charging, the point value settlement between the charging user and the user providing the charging device is still completed through the information management platform. The invention expands the charging resources of the charging device used by the vehicle owner, When the electric power is scarce and there are private charging devices of other vehicle owners nearby, the charging device can be used as long as the vehicle owner ofthe charging device has a personal account of the information management platform, which not only expands the charging range, makes up for the problem of the limited coverage of the public charging device, but also effectively improves the utilization efficiency of the charging device.
