  • Power system of electric vehicle, control method and electric vehicle
    Patent number: 10974600
    Abstract: A power system of an electric vehicle, a control method and an electric vehicle are provided. The system includes a high voltage battery, a low voltage storage battery, a main drive motor and an electronic controller therefor powered by the high voltage battery, and an auxiliary drive motor and an electronic controller therefor. The electronic controller of the auxiliary drive motor includes a high voltage electronic controller and a low voltage electronic controller. The low voltage electronic controller is configured to operate in a rotation speed closed loop mode when determining that the high voltage battery fails, and to operate in a torque control mode to charge the low voltage storage battery when the high voltage battery is normal and state of charge of the low voltage storage battery is lower than a first preset value.
