Abstract: A method for recharging a battery pack (40; 40′) includes attaching a portable charger (120) to a user, which portable charger comprises or is attached to a self-contained power supply (130, 140) and wherein a first charging port (132, 146) of the portable charger is disposed, e.g., on a belt (144) worn by the user, hanging the battery pack on the belt while the battery pack is physically engaged and in electrical communication with a power tool (10; 10′), and initiating a transfer of power from the charger to the battery pack when the first charging port is at least proximal to a second charging port (85, 148) that is in electrical communication with at least one battery cell (50) of the battery pack. A portable charging system capable of performing this method, as well as an adapter for use in performing this method, are also disclosed.

Abstract: A power tool system includes a hand-held power tool having a housing with a battery pack interface, an electrically-driven device and a first connector. A battery pack is detachably attached to the battery pack interface and supplies current to the electrically-driven device. An adapter has a second connector physically and electrically connected with the first connector in a detachable manner. The adapter receives power from the battery pack via the hand-held power tool and provides at least one additional electrical function to the hand-held power tool or performs at least one additional electrical function that the hand-held power tool is not otherwise capable of performing. Further, the adapter is at least partially disposed in a space defined in part by the housing and in part by the battery pack when the housing and battery pack are attached to each other.

Abstract: A power tool includes a power tool housing accommodating a motor; a battery pack interface electrically connected to the motor and being configured to be physically and electrically connected to and disconnected from a power tool interface of a battery pack; and a wireless communicator configured to be attached to or detached from the power tool housing. The wireless communicator wirelessly transmits data between the power tool and an external device using radio waves. In addition, the power tool housing includes a receptacle opening configured to accommodate the wireless communicator within the power tool housing such that no part of the wireless communicator projects or protrudes beyond an outer surface or contour of the power tool 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.
