An apparatus for discharging a high voltage ("HV") battery pack in an electrical system having a low voltage ("LV") bus and a high voltage ("HV") bus includes a resistive load and an electronic control unit ("ECU"). The ECU transmits an electronic control signal to the resistive load to change an output state of the resistive load. As part of a related method, the ECU receives a state of charge ("SOC") of the battery pack and an auxiliary voltage level of the LV bus. The ECU then selectively adjusts the electronic control signal in response to the SOC and the auxiliary voltage level to optimize the output state of the resistive load. This continues until the SOC is within a specified SOC range.

    一种用于对电气系统中的高压(“HV”)电池组进行放电的装置,所述电气系统具有低压(“LV”)总线和高压(“HV”)总线,该装置包括电阻负载和电子控制单元(“ECU”)。ECU将电子控制信号传输到电阻负载以改变电阻负载的输出状态。作为相关方法的部分,ECU接收电池组的荷电状态(“SOC”)和LV总线的辅助电压水平。ECU然后响应于SOC和辅助电压水平选择性地调整电子控制信号,以优化电阻负载的输出状态。这样持续直到SOC处于指定SOC范围内。
