    • The battery pack (1) is connected to an external device (9) and to a power supply circuit (10) for the external device (9), and it energizes the external device (9) or is charged by the power supply circuit (10). Communication is made between a microcomputer (11) inside the battery pack (1) and the external device (9) through terminals (8) and at least information representing a present residual charge of a battery (4) is transmitted from the microcomputer (11) to the external device (9). This residual charge is calculated by the microcomputer (11) using the current, voltage, internal resistance and temperature of the battery (4). In this way, the residual charge can be obtained with a high level of accuracy on the side of the external device (9).
    • 电池组(1)连接到外部设备(9)和用于外部设备(9)的电源电路(10),并且对外部设备(9)通电或由电源电路( 10)。 通过端子(8)在电池组(1)内部的微型计算机(11)和外部设备(9)之间进行通信,并且至少表示电池(4)的剩余电量的信息从微型计算机(11) )到外部设备(9)。 使用电池(4)的电流,电压,内部电阻和温度由微计算机(11)计算该剩余电荷。 以这种方式,可以以高精度在外部装置(9)侧获得剩余电荷。
