The invention provides a discharging method and device of a charging system, equipment and a medium, and the method comprises the steps: controlling a charging interface to be disconnected in response to a discharging request, and obtaining a first voltage of a filter capacitor and a second voltage of a DC bus capacitor; when the first voltage is smaller than a first preset voltage and the second voltage is smaller than a second preset voltage, the filter capacitor and the direct-current bus capacitor are discharged in sequence by controlling the on-off of a loop where the motor and the main relay are located; and discharging control is completed until the voltage of the filter capacitor and the voltage of the direct current bus capacitor are lower than the corresponding target voltage threshold values. Discharging of the charging system can be simply and efficiently completed, and the operation safety of the charging system is guaranteed.

    本申请提出一种充电系统的放电方法、放电装置、设备和介质,所述方法包括:响应于放电请求控制所述充电接口断开,并获取所述滤波电容的第一电压和所述直流母线电容的第二电压;在所述第一电压小于第一预设电压且所述第二电压小于第二预设电压时,通过控制所述电机以及所述主继电器所在回路的开断依次对所述滤波电容和所述直流母线电容进行放电,直到所述滤波电容和所述直流母线电容的电压低于对应的目标电压阈值,完成放电控制。本申请可简单高效的完成充电系统的放电,保证充电系统运行的安全性。
