An electric automobile and a discharging device thereof. The discharging device (100) comprises: an AC charging port (110), the AC charging port being connected to a charging post and the charging post being connected to a power grid, for transmitting an output alternating current to the power grid through the charging post; an instrument (120), for sending a discharging preparation instruction after receiving a trigger signal; a controller (130), for receiving the discharging preparation instruction, detecting whether the AC charging port is connected to the charging post and detecting whether a pulse width modulation (PWM) wave of a preset voltage exists therein, and if yes, switching to an external discharging mode; a battery manager (140), for controlling an external discharging circuit in a high-voltage distribution cabinet attached to an electric automobile after the controller switches to the external discharging mode; and a power battery (150), for providing a direct current through the external discharging circuit in the high-voltage distribution cabinet. The discharging device is advantageous in having simplicity, high efficiency and applicability. |
