The invention provides an electric automobile brake energy recycling method and system. The electric automobile brake energy recycling method comprises the steps that a motor controller preferentiallyreceives a torque instruction of an electronic brake during braking and controls a motor to convert mechanical energy into electric energy to be recycled into a power battery at the same of braking an automobile. According to the electric automobile brake energy recycling method and system, during braking, the electronic brake directly outputs a torque signal to the motor controller without the participation of a vehicle controller so that the logic judging chain is reduced; the recycling rate of the energy can be increased due to the direct response of the motor controller; and moreover, themotor braking is preferentially considered, and mechanical braking is only adopted for supplement in case that the motor braking is not enough; therefore, more energy can be recycled on the premise of guaranteeing the safety of the automobile.
