The embodiment of the invention provides an energy feedback control method and system of an electric vehicle. The technical problem that an existing vehicle energy feedback system is low in braking feedback efficiency is solved. The method comprises the steps of obtaining a vehicle weight load and a brake pedal signal; calculating a braking demand torque based on the vehicle weight load and the brake pedal signal; braking torque distribution is started, and energy feedback is executed. According to the energy feedback control method and system for the electric vehicle provided by the embodiment of the invention, vehicle load calculation and braking force distribution are realized through a pure electric vehicle type driving system, a vehicle control unit VCU and an EBS control system, and the braking comfort and the energy feedback priority privilege of the whole vehicle are ensured. And through EBI braking force distribution of the EBS system, the braking capacity of the driving system is monitored at any time, and braking force distribution of the braking system is conducted according to the energy feedback state of the driving system.
