Abstract
A battery pack configured for discharging to a desired state of charge (SoC) after a fault event that includes a plurality of battery cells and a balancing circuit connected to each of the battery cells. The balancing circuit is configured to measure operational values of each of the battery cells. The battery pack further includes a microcontroller configured to receive the operational values from the balancing circuit, compare the operational values to a prescribed threshold values and issue commands to selectively discharge one or more of the battery cells across the balancing circuit.
