摘要： A battery pack of an electric power tool comprises ten lithium-ion cells. The ten lithium-ion cells are connected in series. Each lithium-ion cell has a diameter equal to or less than 18 millimeters, a length equal to or less than 65 millimeters, and an internal resistance equal to or less than 30 milliohms. Because the battery pack has a high voltage in operation and is therefore able to supply large current, the battery pack is preferably configured incapable of being used in a conventional electric power tool that cannot operate under such a large current.

摘要： A battery pack for an electric power tool includes a control device that determines the necessity of a balancing control to reduce difference in voltages of cells of a battery based upon voltages of the respective cells measured by a voltage measuring device. The control device controls a subject cell, which is subject to the balancing control to discharge via the discharging device when the balancing control is determined to be necessary. A voltage measuring device measures the voltages of the respective cells when a battery charger detecting device detects the connection of the battery charger in a state where the battery has not been connected to the battery charger for a predetermined specified period of time or more and power feeding to the electric power tool has not been performed for the specified period of time or more.

摘要： A rechargeable battery pack attachable to a power tool includes a display element, a remaining capacity detection device, a remaining capacity display control device, an abnormality detection device, and an abnormality display control device. The display element is provided such that a lighted state thereof can be confirmed from outside. The remaining capacity detection device detects a remaining capacity of a rechargeable battery. The remaining capacity display control device displays the remaining capacity detected by the remaining capacity detection device by controlling the lighted state of the display element. The abnormality detection device detects an abnormality of the rechargeable battery. The abnormality display control device displays the abnormality of the rechargeable battery detected by the abnormality detection device by controlling the lighted state of the display element to an abnormality display state, which is different from a remaining capacity display state controlled by the remaining capacity display control device.

摘要： An apparatus for an electric power tool includes a detection unit, a determination unit, a protection unit, a calculation unit, and a notification unit. The calculation unit calculates a time-equivalent value representing a remaining time until a load condition of a battery reaches an overload state, in which the protection unit interrupts a discharge path, based on the result of the detection by the detection unit. The notification unit notifies a user of the electric power tool of a remaining time until the protection unit interrupts the discharge path based on the time-equivalent value calculated by the calculation unit.
