High-voltage control circuit for electric automobile

The utility model provides a high-voltage control circuit for an electric automobile, which comprises a power battery, a positive-electrode contactor, a negative-electrode contactor, a precharge contactor, a precharge resistor, a motor driver with a precharge capacitor, and a rapid discharge circuit. The rapid discharge circuit comprises a discharge resistor and a discharge switch, wherein the discharge resistor is parallelly connected with the precharge capacitor after being serially connected with the discharge switch. When the circuit is cut off, the discharge switch is closed, the discharge resistor and the precharge capacitor form a discharge circuit so that the voltage of the precharge capacitor drops to be below safety voltage.
