The invention provides an energy feedback control method for a full electric vehicle. The energy feedback control method includes the following specific steps that on the premise that an accelerator pedal is released and the vehicle is in a forward gear, whether an ABS is started or not is judged, and if the ABS is not started, the vehicle enters a feedback mode; the feedback mode selection step includes the procedures that after the vehicle enters the feedback mode, whether a brake pedal is trodden or not is judged, if the brake pedal is trodden, the vehicle enters a brake feedback mode, if the brake pedal is not trodden, the vehicle enters a sliding feedback mode, a vehicle control unit calculates feedback torque, and recycled energy is stored in a power battery; when the vehicle enters the brake feedback mode or the sliding feedback mode, whether the ABS is started or not is monitored in real time, and if the ABS is started, the vehicle quits from the feedback mode. The feedback torque is determined through the maximal receiving capacity of the power battery, the actual deceleration working condition of the vehicle and the feedback capacity of a motor, and the driving range of the full electric vehicle is prolonged as much as possible on the premise that vehicle safety is guaranteed.
