The invention provides an electric vehicle discharging device and a control method thereof. The electric vehicle discharging device can transmit electric power of an electric vehicle to an external electric accessory through a direct current charging port. The electric vehicle discharging device comprises a discharging loop, a first control relay module, an energy storage device C1, a second control relay module, a DC/DC power module and a DC/AC power module. Wherein the first control relay module is contained in the discharging loop, the first control relay module is connected with a power battery on the vehicle, and the first control relay module is used for controlling connection and disconnection between the discharging loop and the power battery on the vehicle. The energy storage device is connected with the discharging loop in parallel, and the energy storage device is used for storing energy and can supply power to accessories outside the vehicle and reversely charge a power battery on the vehicle. The second control relay module is connected with the discharge loop and the energy storage device. The second control relay module is used for controlling connection and disconnection between the energy storage device and the discharge loop.
