The invention provides a new energy vehicle braking energy recovery system, method and device and a medium. According to the system, a vehicle control unit is in signal connection with a vehicle-mounted driving system, a motor, a power battery, a left front brake and a right front brake; the vehicle-mounted driving system is used for acquiring a brake pedal opening signal, an accelerator pedal opening signal and a vehicle speed signal of the vehicle and sending the signals to the vehicle control unit; and the vehicle control unit is used for obtaining a brake pedal opening signal, an accelerator pedal opening signal, a vehicle speed signal, a motor signal and a power battery signal of the vehicle, determining whether braking energy recovery is carried out or not, and determining whether mechanical braking intervention is carried out or not according to the power generation torque when the braking energy recovery is carried out. According to the invention, high-efficiency braking energy recovery is realized, the energy utilization rate is improved, and the driving feeling in the braking energy recovery process is improved.
