摘要： A compact battery pack with high handling ability and restraining degradation of battery cells. The battery pack includes an insertion portion to be inserted into a handle portion of a cordless power tool and an accommodation portion in which all battery cells are accommodatable. A protection board with a protection circuit that protects batteries against overcharge and over-discharge is installed in the insertion portion. A switching element is connected between the battery cells and a drive motor of the power tool. An air passage in communication with the battery pack is formed within the handle and a main housing of the cordless power tool. The switching element is positioned at the air passage.

摘要： A charging device has a charging unit and a control unit. The charging unit charges a battery pack the battery pack being either a first type or a second type of battery pack. The first type of battery pack includes a single battery cell or a first plurality of battery cells connected in series. The second type of battery pack includes a single battery unit or a second plurality of battery units connected in series. Each battery unit includes at least two battery cells connected in parallel. The control unit controls the charging unit to control at least one of a charging current flowing through the battery pack and a charging voltage applied across the battery pack, depending on the battery pack to be charged.

摘要： To prevent a battery pack from being over-discharged even under a state that the battery pack (a secondary battery) is connected to a discharging device that is not connected to an ac input power source for a long time. A charging device 200 has a pair of output lines L1 and L2 and an anode terminal O1 and a cathode terminal O2 of a secondary battery 2 electrically connected between the output lines L1 and L2 to carry out a charging operation. In the charging device 200 including a component circuit part (a resistance 33, a series connecting circuit of resistances 102, 103 and 105, a series connecting circuit of resistances 91 and 92 and an inner circuit part of a shunt regulator 116) electrically connected by traversing a part between the pair of output lines L1 and L2, a switching element 121 is inserted between the component circuit part (the resistance 33 or the like) and one of the pair of output lines L1 and L2. When the charging device 200 is not connected to an input power source 1, the switching element 121 is allowed to be non-conductive to interrupt a discharging path so that the component circuit part does not form the discharging path.
摘要翻译：即使在电池组（二次电池）连接到长时间未连接到交流输入电源的放电装置的状态下，也可防止电池组过度放电。充电装置200具有一对输出线L 1和L 2以及电连接在输出线L 1和L 2之间的二次电池2的阳极端子O 1和阴极端子O 2，以执行充电操作。在包括组件电路部分（电阻33，电阻102,103和105的串联连接电路，电阻91和92的串联连接电路和分流调节器116的内部电路部分）的充电装置200中，电连接穿过一对输出线L 1和L 2之间的部分，开关元件121插入在组件电路部分（电阻33等）和一对输出线L 1和L 2中的一个之间。当充电装置200未连接到输入电源1时，允许开关元件121不导通以中断放电路径，使得元件电路部分不形成放电路径。
