The motor 5 adopts PWM speed regulation, and also includes an encoder 10 arranged on the driving wheel of the vehicle.

In the working process of the utility model, when the car is running, the brake pedal 1 is stepped on. When the brake pedal 1 is stepped on, it first enters the braking stage of the electromagnetic retarder. Inside, according to the different stepping strokes, the potentiometer 2 will generate different voltage signals, and the voltage signals will be transmitted to the control system. After the control system analyzes and processes the voltage signals, it will be connected to the corresponding voltage of the excitation coil of the electromagnetic retarder 8 to generate Braking torque. In the case of a constant excitation coil voltage, the braking torque changes in direct proportion to the transmission shaft speed, so the higher the vehicle speed, the greater the braking torque generated;

When braking, the electric energy generated by the rotor winding is quickly stored in the supercapacitor bank of the energy storage device 9. After braking, the supercapacitor bank starts to discharge, and is used to charge the battery after passing through the voltage stabilizing circuit, thereby realizing energy conversion. storage;

At this time, the motor 5 and the electromagnetic retarder 8 provide power for starting at the same time, so as to realize the conversion and utilization of energy. After the wheel speed reaches the set value, the speed of the transmission shaft 6 has exceeded the speed of the auxiliary power unit at the rated voltage, and the control unit cuts off the retarder power supply.
