Anti-theft charging system

An anti-theft charging system for charging a chargeable battery of an electric vehicle, said anti-theft charging system comprising:

• a power supplying device for outputting a charging energy;
• an output terminal assembly electrically connected with said power supplying device and detachably coupled to said electric vehicle for receiving and transmitting said charging energy to said chargeable battery;
• and
• a burglarproof detecting device comprising a responding unit and a detecting unit, wherein said responding unit is disposed within said output terminal assembly for issuing a response signal, and said detecting unit is disposed within said power supplying device and in signal connection with said responding unit for detecting said response signal;
• wherein said output terminal assembly further comprises a cable group and a charging gun, wherein said cable group is electrically connected between said power supplying device and said charging gun, and said responding unit is disposed within said charging gun;
• wherein said responding unit comprises a first resistor, wherein an impedance change of said first resistor constitutes said response signal;
• wherein said detecting unit comprises:
• an impedance detecting unit electrically connected with said first resistor for outputting a first detecting signal and a second detecting signal, wherein when said anti-theft charging system is in an operating mode, said first detecting signal reflects whether an impedance of said first resistor is changed, wherein when said anti-theft charging system is in a standby mode, said second detecting signal reflects whether an impedance of said first resistor is changed;
• and
• a controlling unit electrically connected with said impedance detecting unit for outputting a control signal to said impedance detecting unit, thereby controlling a corresponding action of said impedance detecting unit, wherein when said anti-theft charging system is in said operating mode, said controlling unit judges whether said output terminal assembly is separated from said power supplying device according to a change of said first detecting signal, wherein when said anti-theft charging system is in said standby mode, said controlling unit judges whether said output terminal assembly is separated from said power supplying device according to a change of said second detecting signal.
