Abstract
A control module is included in a battery charger that is adapted to charge a plurality of battery packs of different types or a power tool that is adapted to be powered by at least one of the battery packs. The control module includes a remote sensing module that communicates remotely with one of the battery packs. The control module also includes a battery pack connection module that determines that the one of the battery packs is in electrical communication with at least one of the battery charger and the power tool. The control module also includes a battery pack identification (ID) module that determines a first type of the battery pack based on remote sensing module signals. The control module also includes a charge control module that determines at least one of a charge setting and a discharge setting for the battery pack based on the first type.
