Abstract: A system supplies supplemental power to a power tool. The system includes a motor coupled to an output driver, a trigger for user control of power tool operation, a sensor configured to measure an operation characteristic, a battery pack coupled to the motor, and an auxiliary energy supply. A motor controller receives a control signal from the trigger and drives the motor utilizing energy from the battery pack in response to the control signal. The motor controller also receives information from the sensor and provides additional energy to the motor from the auxiliary energy supply depending on the information from the sensor (e.g., motor speed, motor rotational position, motor current, or trigger pull percentage). The controller may connect the auxiliary energy supply in series with the battery pack to supply the supplemental power. A battery charger or energy recapture may be utilized to charge the auxiliary energy supply.

Abstract: A charger includes a housing with an interface positioned in a front wall and configured to engage a battery pack. The interface includes charging terminals positioned between a first rail and a second rail, a first groove positioned between the first rail and a wall of the housing, and a second groove positioned between the second rail and the wall of the housing. The interface is in communication with an interior of the housing. A fan is coupled within the housing adjacent the interface, and an air passage member includes a hollow body that has a first end coupled to the fan and a second end spaced apart from the first end extending through another wall of the housing. The fan is operable to suck an air flow into the housing from outside the housing and guide the air flow through the air passage member to the interface.

Abstract: A battery pack and a method of inhibiting failure of a battery pack. The battery pack may generally include a housing; a battery cell supported in the housing and electrically connectable to an electrical device, power being transferrable between the battery cell and the electrical device; a resistor supported in the housing and operable to receive current from the battery cell; and an electronic processor configured to detect a failure condition of the battery pack, and, in response to detecting the failure condition of the battery pack, cause the battery cell to discharge through the resistor.

Abstract: The present invention relates to a battery pack including a housing, a latch mechanism, a printed circuit board connected to electrical terminals, and an internal frame. The housing includes a first and second portion. The first portion includes openings that receive the latch mechanism and openings that receive the terminals. The battery pack also includes a latch cover that protects against water infiltrating between the openings and the latch mechanism, and a terminal cover that protects against water infiltrating between the first housing portion and the terminals. Water that enters the battery pack is directed to the bottom of the battery pack. The water is then drained through openings in the lower housing portion. The internal frame includes openings that secure batteries within the lower housing portion with the help of wedges that are positioned in between adjacent rows of batteries.
