Claims22
A battery pack charging system for a power tool, the battery pack charging system comprising:
- a battery pack including:
- at least one battery cell and a housing, the housing defining an interior region;
- a battery charging circuit including a microcontroller, the battery charging circuit disposed within the interior region of the housing of the battery pack;
- a USB charging port disposed on the housing of the battery pack;
- a battery source module for delivering DC power to the USB charging port of the battery pack, the power source module including an AC/DC power circuit.
A battery pack charging system for a power tool, the battery pack charging system comprising:
- a battery pack including a housing defining an interior region, at least one battery cell disposed within the interior region of the housing, a USB charging port accessible along an exterior region of the housing, and a battery terminal interface for connection to one of a battery charger and the power tool;
- a power source module separate from the battery pack, the power source module including an AC/DC power circuit, and a USB power delivery controller for delivering power to the USB charging port of the battery pack.
A battery pack charging system for a power tool, the battery pack charging system comprising:
- a battery pack including a housing defining an interior region, at least one battery cell disposed in the interior region, a battery charging circuit having a microcontroller, a USB charging port accessible along the housing, a memory, and a battery terminal interface;
- a power source module for providing DC power to the USB charging port of the battery pack, the power source module including an AC/DC power circuit, a memory, and provisions for data transfer between the battery memory and the memory of the power source module;
- wherein the power source module is separate from the battery pack.
