Abstract
A portable battery charger (102) for use with a variety of battery packs (106) is capable of determining and applying the appropriate charge voltage and current. Electronic circuitry (128) within the portable battery charger identifies the type of battery pack to be charged and selects the appropriate set of battery banks (120) in the charger. Sensors (132) determine the state of charge of the battery pack and a controller (128) controls the functions of the charger. A multiplicity of connectors (314) on the portable battery charger are provided to allow connection to a variety of battery packs. The charger first identifies the type of battery pack and determines the charging profile to be used to charge the battery pack. The charging profile is set in the portable charger by selecting the appropriate sources of electrical power, and the battery pack is then appropriately charged.
