A charging system that facilitates tracking of a stolen charging subject. The charging subject includes a battery and has a unique identification code. A charging device is connected to the battery of the charging subject by an electric cable, and the battery is chargeable. A server is connected to either one of the charging device and the charging subject and manages charging of the charging subject with the charging device. The server is cable of registering an identification code of the charging subject. The server obtains the identification code from the charging subject, determined whether or not the obtained identification code is registered in the server, and transmits to the charging device a charging prohibition command for prohibiting charging of the charging subject with the charging device when the obtained identification code is not registered in the server.
