Abstract Electric vehicles (EV) is supplied with the battery. To extend the driving range of EV, braking and deceleration energy should be fully utilized. In order to improve the braking safety and comfort of EV, constant current regenerative braking control strategy based on model predictive current control strategy is proposed in this paper. Brushless DC Motor (BLDCM) regenerative braking principle under single modulation is described. The mathematical model of regenerative braking is established. The closed-loop control system of braking current is established. Regenerative braking current is controlled with model predictive current control strategy. Regenerative braking current and torque is kept to be constant. The effectiveness of the proposed method is verified by experimental results. The brake current and torque are stable during braking.

Key words： Brushless DC motor(BLDCM) electric vehicle(EV) model predictive current control regenerative braking
