Title: POWER TOOL, BATTERY PACK, AND COMBINATION, AND METHOD OF CONTROLLING THE SAME
Abstract:
A battery pack, power tool, and power tool combination. The battery pack includes one or more battery cells, a first terminal electrically connected to the one or more battery cells, a high current power supply terminal, a power switch electrically connected between the one or more battery cells and the high current power supply terminal, and a low current power supply terminal electrically connected to the one or more battery cells. The first terminal and low current power supply terminal are operable to provide a substantially continuous low current to the power tool during a normal operating state of the battery pack. The battery pack also includes a controller operable to control the power switch to provide high current power through the high current power supply terminal in response to a call for power from the power tool.
