Abstract
A battery charging system includes a battery management module and a battery charger. The battery charging system provides controlled charging in accordance with an algorithm utilizing historical battery data. The historical battery data is data pertaining to the historical status of the battery, and is acquired while the battery is in service and during previous charge cycles. The historical battery data is stored in memory in the battery management module. In one embodiment of the battery charging system, the battery management module is physically and electrically coupled to the battery during service and during charging. The historical battery data is provided to the battery charger during charging. The historical battery data is used to provide parameters to a charging algorithm, wherein the battery charging system provides controlled charging of the battery in accordance with the algorithm.
