    摘要： A battery pack may include a plurality of battery cells; a discharge switch in series with the battery cells, a temperature sensor configured to sense temperature in the battery pack, and a battery control unit adapted to receive a signal indicative of temperature from the temperature sensor and operable to control the switch to interrupt current flow from the battery cells when the temperature exceeds an over-temperature threshold. The battery control unit may be adapted to receive a reset signal and operable to control the switch to restore current flow upon receipt of the reset signal and when the temperature is below an operating temperature threshold.

    摘要： A dual-mode system for inexpensively operating electrically powered double-insulated devices (12), such as hand-held power tools and appliances. The system includes a cordless battery power module (14) that supplies the power and current demands of the device (12) in a cordless mode or a chopper module (21) that supplies the necessary power and current demands in a physical envelope commensurate in size and interchangeable with that of the battery power module (14). The chopper module (21) is provided with a non-filtered high efficiency converter circuit that allows the chopper module (21) to generate the power and current required by the driven device (12). The inductance of the motor (11) for the driven device (12) is used to filter the output of the chopper module (21). Eliminating the output filter from the chopper module (16) significantly reduces the cost and size of the module (16). Additionally, the need for multiple battery packs and fast rechargers is minimized by the availability of a low-cost converter. The line power module (16) includes an EMI filter (15) for filtering AC or DC input power. The chopper module (21) chops the filtered voltage, providing a series of voltage pulses having a DC voltage level that is suitable for driving the motor (11).

    摘要： A method is provided for charging a plurality of cells in a battery pack to a target charging value. The method includes: delivering a charging current to the plurality of cells; monitoring cell voltage of each cell in the plurality of cells to determine when at least one of the cells reaches the target charging value; and diverting the charging current around the cells having reached the target charging value and cooperatively adjusting the charging current so that a current received by the cells having reached the target charging value is substantially zero.
