Abstract: A method and system for wirelessly tracking power tools and related devices to aid with inventory management and to help minimize, prevent, and recover misplaced or stolen tools throughout the job site. The tools and/or batteries include wireless transmitting capabilities (e.g., an ISM unit) to transmit data to a fob, puck repeater, and/or gateway over an ISM network. The gateway is operable to translate and output the ISM communications over a cellular network to a remote monitoring unit, such as a personal computer or smart phone. Additionally, the gateway is further operable to translate and output cellular communications from the remote monitoring unit to ISM communications over the ISM network. A wireless tethering system and method is also disclosed whereby an ISM battery places a power tool in a lock-out or limp mode after the ISM battery remains outside of ISM communications for a prolonged period of time.

Abstract: A method for conducting an operation including a power tool battery pack. The battery pack can include a housing, a first cell supported by the housing and having a voltage, and a second cell supported by the housing and having a voltage. The battery pack also can be connectable to a power tool and be operable to supply power to operate the power tool. The method can include discharging one of the first cell and the second cell until the voltage of the one of the first cell and the second cell is substantially equal to the voltage of the other of the first cell and the second cell.

Abstract: An electrical combination including a power tool and a battery pack. The power tool includes power tool terminals. The battery pack is configured to be interfaced with the power tool. The battery pack includes a battery pack housing, at least three terminals, and a plurality of battery cells. The battery pack terminals include a positive terminal, a negative terminal, and a sense terminal. The at least three terminals are configured to be interfaced with the power tool terminals. The plurality of battery cells are arranged within and supported by the battery pack housing. Each of the battery cells has a lithium-based chemistry and a respective state of charge, and power is transferable between the battery cells and the power tool. A circuit is configured to monitor the battery cells, detect a charge imbalance among the battery cells, and prevent the battery pack from operating when the charge imbalance is detected.

Abstract: An electrical combination. The electrical combination comprises a battery pack configured to be interfaced with a hand held power tool, a control component, and a semiconducting switch. The transfer of power from the battery pack to the hand held power tool is controlled by the control component and the switch based on one of a battery pack state of charge and a respective state of charge of one of a plurality of battery cells. A discharge current of the battery pack is regulated based on the switch being controlled into one of a first state and a second state by the control component to selectively enable the transfer power from the plurality of battery cells to the hand held power tool.
