Abstract
A rechargeable battery pack is discontinuously charged in multiple discrete charging intervals. Reductions in battery pack voltage that occur during non-charging intervals, each transpiring between a respective pair of the discrete charging intervals, are measured. Multiple resistance values that characterize the internal resistance (DC resistance) of the battery pack are generated based on the reductions in battery pack voltage that occur during the non-charging intervals.
