Abstract: A power tool system includes a hand-held power tool, a battery pack and an adapter. The hand-held power tool includes a power tool housing that accommodates a motor, and a battery pack interface electrically connected to the motor. The battery pack includes a battery pack housing that accommodates at least one battery cell, and a power tool interface electrically connected to the at least one battery cell. The power tool interface is configured to be physically and electrically connected to and disconnected from the battery pack interface of the power tool. The adapter includes a wireless communicator configured to wirelessly communicate data to/from an external device using radio waves, a self-contained power supply configured to supply electric power to the wireless communicator and an interface configured to attach the adapter to the power tool housing and/or the battery pack housing.

Abstract: A power tool includes a motor and a controller in a power tool housing. A battery pack interface is defined on and/or in the power tool housing. A receptacle is defined on and/or in the power tool housing to removably accommodate a wireless communication adapter such that the wireless communication adapter is disposed entirely within a shell of the power tool and no portion of the wireless communication adapter extends beyond an outer contour of the power tool housing. At least one communication terminal is disposed within the receptacle and is electrically connectable to the wireless communication adapter. The controller outputs to the at least one communication terminal a signal indicating a charge level of a battery pack attached to the battery pack interface, a number of hours of operation of the power tool, a power tool overheated alert, and/or a battery pack overloaded alert.
