摘要： A device 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 electronic control signals 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 signals in response to the SOC and auxiliary voltage level to optimize the output state of the resistive load. This continues until the SOC is within a specified SOC range.
