Analysis of motor energy feedback strategy for electric vehicles

The shortage of the endurance of electric vehicles has seriously affected its promotion. The reasonable use of the dual characteristics of electric and power generation of motors can effectively extend the endurance mileage of electric vehicles by making energy feedback during braking. By introducing the braking characteristics of electric vehicles, this paper analyzes and compares two conventional motor energy feedback braking strategies, and proposes a strategy based on maximum allowable braking torque control, which can effectively ensure the safety of energy regenerative braking. Finally, with the powerful simulation function of MATLAB, the three motor energy feedback strategies are simulated and compared to highlight their advantages and disadvantages more intuitively.
