摘要： A method and a system for a high-voltage (HV) battery pack having multiple rechargeable energy storage devices (RESSs) that are connectable to an external load via a power bus via a pre-charge circuit in parallel with a first electrical contactor. The RESSs are monitored via current sensors. The current sensors monitor current levels between the RESSs 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 the respective pre-charge circuit, monitor the electrical current, and determine a state of the respective first electrical contactor based upon the electrical current.
