Abstract
A charging strategy for a rechargeable battery pack is disclosed. The battery pack is used in an application that includes a dynamoelectric machine that may operate as a motor, drawing power from the battery pack, or as a generator, delivering regenerative energy to the battery pack. The strategy monitors the nature, intensity, duration and frequency, among other things, associated with encountered episodes of regenerative energy from the dynamoelectric machine, and adjusts subsequent recharging processes to allow a calculated amount of headroom to accommodate regenerative energy inputs in the future, which may be assumed to be equal in nature, intensity, duration and frequency to what has already been observed. Overcharging is reduced or eliminated, while maximizing the amount of charge on the battery pack, and thus duration of use.
