    Abstract: In a cordless power tool system, high temperature gases created in a battery pack by the battery cells during a charging or discharging operation can be routed into a housing of one of an attached power tool or charger to reduce the temperature of the gases, prior to venting the gases externally. In an example, a battery pack has at least one vent hole for relieving pressure and a movable device covering the vent hole and configured to expose the vent hole upon a pressure set-point within the pack housing being exceeded. In another example, the pack housing includes a thin-walled section designed to break if pressure within the pack housing exceeds a given pressure setpoint. In a further example, the pack housing includes a baffle having an S-shaped cross-section for providing a vent path for gases and for preventing external fluids from entering the pack housing.

  • Patent number: 7723951
    Abstract: The embodiments of the invention relate to a novel apparatus and method for a battery charging system in a shared environment, as well as for monitoring battery usage and tracking battery location. In one embodiment, the battery charging chute comprises a housing configured to receive a battery via an insertion slot and configured to dispense a battery through a dispensing slot. Within the housing, charging terminals are disposed is a spaced or continuous manner, to come in contact with the charging terminals on batteries inserted into the housing. Optionally, solenoid-controlled gates may be employed at the insertion slot and dispensing slot, to inhibit the removal or insertion of batteries from the incorrect location, to ensure that the battery with the longest residence time in the chute is dispensed to a user. The housing may also include a radio-frequency identification tag reader to permit inventorying and tracking of batteries inserted into the housing.

  • Patent number: 7719234
    Abstract: In a cordless power tool system, a battery pack which may removably attachable to a cordless power tool and to a charger may include at least one battery cell and a power limiting device. The power limiting device may be arranged in series with the at least one battery cell for limiting power output of the battery pack based on the component that is connected to the pack. Current and hence power out of the battery pack may be controlled as a function of total internal impedance in the battery pack, which may be adjusted depending on the component that is connected to the pack.

  • Patent number: 7714532
    Abstract: Safety against error setting of a primary battery in a dedicated battery charger for secondary batteries can be assured even when the battery charger is of a timer type advantageous for cost reduction. A switching circuit (2) is connected between terminals (13, 15), and terminals (14, 16) are connected. Terminals (15, 17) are connected, and terminals (16, 18) are connected. The positive pole of a battery (3) set in position is connected to the terminal (17), and the negative pole is connected to the terminal (18). A battery discriminating circuit (4) connects to the positive pole and the negative pole of the battery (3) set in position; and judges whether the battery (3) is a primary battery or a secondary battery. Depending upon the result of the discrimination, the battery discriminating circuit (4) supplies a switching signal to the switching circuit (5) to turn it on or off. A capacitor (6) and a resistor 7 are connected in parallel between a timer circuit (9) and a ground potential.
