Abstract: 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.
Abstract translation: 电动工具的电池组包括十个锂离子电池。 十个锂离子电池串联连接。 每个锂离子电池的直径等于或小于18毫米，长度等于或小于65毫米，内阻等于或小于30毫欧。 由于电池组在工作中具有高电压并且因此能够提供大电流，所以电池组优选地被配置为不能用于不能在这样大的电流下操作的常规电动工具。

Abstract: One aspect of the present disclosure provides a battery pack including a rechargeable battery, a first power supply terminal, a second power supply terminal, a first signal terminal, a second signal terminal, a positive-side current path, a negative-side current path, a temperature signal generation circuit, a biasing circuit, and a control circuit. The temperature signal generation circuit (i) includes a temperature detection device and (ii) generates a temperature signal across the first signal terminal and the second signal terminal. The temperature detection device has a variable resistance that is dependent on a battery temperature. The temperature signal has a voltage associated with the variable resistance. The biasing circuit biases the voltage of the temperature signal. The voltage biased makes an external device reduce or stop (i) charging from the external device to the rechargeable battery and/or (ii) discharging from the rechargeable battery to the external device.
