Battery locomotive power generation feedback brake and basic braking system

In the process of subway battery locomotive running, when the speed of the frequency converter is lower than the traction motor, the motor will enter the generator state. In this state, the frequency converter can efficiently feed the electric power of the motor to the accumulator (to recharge the battery).The power generated by the motor in the generation feedback process is very strong, which is equal to or exceeds the maximum traction of the battery locomotive, and the higher the speed of the battery locomotive, the greater the power of the system
