The invention provides a hand brake braking system and method for electric automobiles. The system comprises a collection device, a vehicle control unit, a motor controller and a battery management system. The collection device is used for collecting hand brake state signals of an electric automobile and sending the hand brake state signals to the vehicle control unit, wherein the hand brake state signals include hand brake braking signals and hand brake release signals. The vehicle control unit is used for sending first commands and second commands to the motor controller and the battery management system respectively when receiving the hand brake braking signals in the running process of the electric automobile. The motor controller, when receiving the first commands, enables a drive motor to operate with a first preset torque until the electric automobile stops running. The battery management system, when receiving the second commands, controls a power battery to perform energy recovery. According to the invention, the braking performance of vehicles is improved, braking energy recovery is realized and the energy utilization rate is increased.
