The invention provides a direct current V2V discharge control method and device, and relates to the technical field of vehicles. The method comprises the steps that under the condition that a direct current V2V conduction connection assembly is connected between a charging vehicle and a discharging vehicle, the current battery voltage of the charging vehicle is obtained; the output voltage of the discharging vehicle is adjusted to a target voltage range by controlling the capacitor voltage of an original capacitor in the power transmission circuit, and the target voltage range comprises the current battery voltage; under the condition that the battery is disconnected from the power transmission circuit, the power transmission circuit of the discharging vehicle and the power transmission circuit of the charging vehicle after voltage adjustment are controlled to be conducted; when the power transmission circuit of the discharging vehicle and the power transmission circuit of the charging vehicle are electrically connected, the charging vehicle is discharged by the range extender. Through the technical scheme provided by the embodiment of the invention, the direct current V2V discharge cost can be reduced.
