A method and system for a high voltage (HV) battery pack having a plurality of rechargeable energy storage devices (RESs) connectable to an external load via a power bus via a pre-charge circuit in parallel with a first electrical contactor. The RESS is monitored via a current sensor. The current sensors monitor a current level between the RESS and the power bus, detect a low current level from one of the current sensors, identify one of the RESSs associated with the low current level, activate a corresponding pre-charge circuit, monitor a current, and transmit the current to the RESSs associated with the low current level to the one of the RESSs associated with the one of the RESSs associated with the one of the RESSs associated with the one of the RESSs associated with the one of the RESSs. And determining a state of the respective first electrical contactor based on the current.

    一种用于具有多个可再充电式能量存储设备(RESS)的高压(HV)电池组的方法和系统,所述多个可再充电式能量存储设备(RESS)可经由与第一电气接触器并联的预充电电路、经由电力总线连接到外部负载。经由电流传感器监测所述RESS。所述电流传感器监测所述RESS与所述电力总线之间的电流水平,检测来自所述电流传感器中的一个电流传感器的低电流水平,识别所述RESS中与所述低电流水平相关联的一个RESS,激活相应的预充电电路,监测电流,并且基于所述电流确定所述相应第一电气接触器的状态。
