The invention provides a discharging device and a discharging method, and relates to the technical field of charging and discharging. The discharging device comprises a DC-DC conversion module which is connected with a power battery of an electric vehicle; a DC-AC conversion module, which is connected with the DC-DC conversion module and an external power grid; and a zero cross detection module, which is connected with the DC-AC conversion module and a live/zero line of the power grid; wherein the zero cross detection module sends an electric signal representing a discharge instruction to the DC-AC conversion module when detecting that the voltage of electricity is zero, and the DC-AC conversion module discharges to the power grid within a preset duration after receiving the electric signal. According to the scheme, high-power discharging of the electric automobile is achieved.
