摘要： A battery pack for a power tool of self-contained over-charge protection is proposed. The battery pack includes a battery stack composed of a plurality of series connected secondary cells, and a charge terminal connected through a charge current path to the battery stack for flowing a charge current from a charger. The battery pack includes an interrupter inserted in the charge current path, and an over-charge detector which detects a cell voltage across each of the secondary cells and actuates the interrupter to open the charge current path when any one of the cell voltages becomes higher than a predetermined threshold (VTH3). Thus, even if the charger fails to limit the charge current, the battery pack can itself protect the secondary cells from being over-charged.

摘要： A battery pack for a power tool has a less-current consuming over-discharge protection. The battery pack includes a battery stack composed of a plurality of series connected secondary cells, and a discharge detector configured to monitor a cell voltage across each of the secondary cells and to provide a discharge stop signal when any one of the cell voltages becomes lower than a predetermined threshold. The discharge stop signal is fed to deenergize the power tool. The discharge detector is composed of a voltage monitor and a power controller. The voltage monitor includes a plurality of comparators and a plurality of constant voltage elements each providing a constant voltage determining the threshold. Each comparator is configured to compare each cell voltage with the threshold to give a comparison result. The voltage monitor is energized by the battery stack to provide the discharge stop signal based upon the comparison results. The power controller is configured to energize the voltage monitor when the battery pack is connected to the power tool. Thus, the discharge detector is protected from consuming the energy of the battery pack while being disconnected from the power tool.
