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 charging control system. The system has a function as a switch controller which includes a charge mode judging executor 66, a charging time monitoring executor 68 and a switch controlling executor 72. The executor 66 judges whether present control is a constant current control or a constant voltage control. The executor 68 monitors whether or not a constant current charging time exceeds a threshold time by utilizing a judging result of the executor 66. The executor 72 turns a switch 54 off when a monitoring result of the executor 68 indicates that the constant current charging time exceeds the threshold time.

摘要： A charger includes an output circuit unit to output a charging current to a secondary battery, a voltage detection unit to detect a voltage of the secondary battery, and a control unit to control the output circuit unit, whereby constant current charging and constant voltage charging are performed. The control unit decreases a constant current value of the charging current by stages during the constant current charging and determines that the secondary battery has deteriorated by using a first voltage drop value of the secondary battery occurring upon first conversion and a second voltage drop value of the secondary battery occurring upon second conversion.

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.
