The embodiment of the invention discloses a capacitor discharging method, a capacitor discharging device, electronic equipment and a storage medium. The method comprises the following steps: responding to an active discharging control signal received by a motor controller, and detecting the switching states of a main positive relay and a main negative relay and the rotating speed of a motor; controlling a bus capacitor to discharge the motor by the motor controller if the main positive relay and the main negative relay are in an off state and the rotating speed of the motor reaches a first threshold value; and responding to the fact that the voltage of the bus capacitor is reduced to a second threshold value, and controlling the bus capacitor to stop discharging the motor by the motor controller. Therefore, the capacitor discharging time can be effectively shortened; and additionally, the capacitor discharging process is controlled to be safe and reliable through the motor controller in the high-voltage loop, so the safety performance of the vehicle after high-voltage outage is improved.

    本公开实例公开了一种电容放电方法和装置、电子设备和存储介质,其中,方法包括:响应于电机控制器接收到主动放电控制信号,检测主正继电器和主负继电器的开关状态、以及电机的转速;若主正继电器和主负继电器处于断开状态且电机的转速达到第一阈值,则电机控制器控制母线电容对电机进行放电;响应于母线电容的电压降低到第二阈值,电机控制器控制母线电容停止对电机进行放电。由此,本公开实施例可以有效缩短电容放电时间,此外,利用高压回路中的电机控制器控制电容放电过程安全可靠,提升了整车高压断电后的安全性能。
