1. A discharging apparatus for an electric vehicle, comprising:

  • an AC charging interface;

    a charging connection device, having a first terminal connected with the AC charging interface of the electric vehicle and a second terminal connected with another electric vehicle, and configured to transmit an AC output from the AC charging interface to the another electric vehicle;

    an instrument, configured to send a discharging preparation instruction after receiving a trigger signal;

    a controller, configured to communicate with the instrument and to detect whether the charging connection device is connected with the AC charging interface after receiving the discharging preparation instruction, and if yes, to emit a PWM wave and to switch to an external discharging mode;

    a battery manager, configured to communicate with the controller and to control an external discharging circuit in a high-voltage distribution box of the electric vehicle after the controller switches to the external discharging mode;

    a power battery, connected with the high-voltage distribution box and configured to provide a DC via the external discharging circuit in the high-voltage distribution box;

    wherein the controller is configured to detect whether the another electric vehicle is fully charged, and if no, the controller converts the DC provided by the external discharging circuit into the AC and to output the AC to the AC charging interface so as to discharge to the another electric vehicle.
