The invention provides a charging device for an electric vehicle, which comprises a power supply connector, a power receiving connector, a safe charging signal generating unit and a CAN control module, wherein the power supply connector is provided with one of a charging terminal and a charging terminal accommodating chamber; the power receiving connector is provided with the other one of the charging terminal and the charging terminal accommodating chamber; the safe charging signal generating unit is arranged on the charging device; the CAN control module receives a safe charging signal generated by the safe charging signal generating unit; and when the charging terminal and the charging terminal accommodating chamber are mutually connected and the power supply connector, the power receiving connector are mutually combined and the CAN control module detects the safe charging signal, the charging device charges the electric vehicle. The charging device adopts a double-insurance structure combining a mechanical structure and a CAN control module, so safety hazards caused by accidents, misoperation and the like to operators are avoided.
