Active discharge control method and device of bus capacitor and electronic equipment

The invention provides an active discharge control method and device for a bus capacitor and electronic equipment, and the method comprises the steps: a motor controller receives an active discharge instruction outputted by a vehicle control unit, and judges whether to enter an active discharge mode or not; after it is judged that the active discharge mode is entered, a first reference current given value is calculated; completing active discharge operation according to the first reference current given value; and quitting the active discharge mode after judging that the active discharge quitting condition is met. According to the invention, active discharge can be completed without adding other equipment, the discharge speed is adjustable, and the vehicle is prevented from shaking in the discharge process. 本发明提供一种母线电容的主动放电控制方法、装置及电子设备，包括：电机控制器接收整车控制器输出的主动放电指令，并判断是否进入主动放电模式；判断进入主动放电模式后，计算第一参考电流给定值；根据所述第一参考电流给定值完成主动放电操作；判断符合主动放电退出条件后退出主动放电模式。本发明能够实现不增加其他设备的情况下完成主动放电，放电速度可调并防止车辆在放电过程中发生抖动。
