Battery pack identification system
First Claim
1. A battery charger adapted to charge a plurality of battery packs of different types, comprising:
- a plurality of terminals, wherein the battery charger electrically communicates with one of the battery packs through said plurality of terminals;
a remote communication device that generates signals in response to remote detection of said one of the battery packs; and
a control module comprising a remote sensing module that receives signals from said remote communication device,said control module further comprising a battery pack connection module that determines that said one of the battery packs is in electrical communication with the battery charger based on communications with said one of the battery packs through said plurality of terminals,said control module further comprising a battery pack identification (ID) module that determines a first type of said one of the battery packs based on remote sensing module signals, andsaid control module further comprising a charge control module that determines a charge setting for said one of the battery packs based on said first type.

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.
