An anti-theft charging system (1) for charging a chargeable battery of an electric vehicle is disclosed and includes a power supplying device (11), an output terminal assembly (12), and a burglarproof detecting device (10). The power supplying device (11) is used for outputting a charging energy. The output terminal assembly (12) is electrically connected with the power supplying device (11) and detachably coupled to the electric vehicle for receiving and transmitting the charging energy to the chargeable battery. The burglarproof detecting device (10) includes a responding unit (101) and a detecting unit (100). The responding unit (101) is disposed within the output terminal assembly (12) for issuing a response signal, and the detecting unit (100) is disposed within the power supplying device (11) and in signal connection with the responding unit (101) for detecting the response signal. If the output terminal assembly (12) is stolen, the detecting unit (100) realizes that the output terminal assembly (12) is stolen according to a change of the response signal.
