    • A storage device allows the state of charge of a main battery to be determined by measuring the state of charge of a dummy battery. The storage device may provide power to an electronic appliance such as a portable computer. The main and dummy batteries each have a storage capacity and a self-discharge rate. The storage capacity of the dummy battery is less than the storage capacity of the main battery; for example, the storage capacity of the dummy battery may be only about 1% of that of the main battery. The main and dummy batteries are configured so that the self-discharge rates thereof are substantially equal. The storage device also includes discharge circuitry which is configured so that the dummy battery discharges at a rate faster than the main battery when a load is connected to and drawing current from the main battery.
    • 存储装置允许通过测量虚拟电池的充电状态来确定主电池的充电状态。 存储设备可以向诸如便携式计算机的电子设备提供电力。 主电池和虚拟电池各自具有存储容量和自放电率。 虚拟电池的存储容量小于主电池的存储容量; 例如,虚拟电池的存储容量可以仅为主电池的容量的约1%。 主电池和虚拟电池被配置成使其自放电率基本相等。 存储装置还包括放电电路,其被配置为使得当负载连接到主电池并从主电池吸取电流时,虚拟电池以比主电池快的速率放电。

    • A battery pack includes battery storage. The battery storage has a positive terminal and a negative terminal. A power connector is connected to the positive terminal of the battery storage. A ground connector is to the negative terminal of the battery storage. The battery pack also includes an additional connector. Battery monitoring circuitry is used to monitor the battery storage. The battery monitoring circuitry has a power input. Disconnect circuitry is connected to the positive terminal of the battery storage, to the ground connector, to the additional connector and to the power input of the battery monitoring circuit. The disconnect circuitry, in response to a first voltage pattern on the additional connector, electrically connects the power input of the battery monitoring circuitry to the positive terminal of the battery storage. In response to a second voltage pattern on the additional connector, the disconnect circuitry electrically disconnects the power input of the battery monitoring circuitry from the positive terminal of the battery storage.
    • 电池组包括电池存储器。 电池存储器具有正端子和负端子。 电源连接器连接到电池存储器的正极端子。 接地连接器是电池存储器的负极端子。 电池组还包括一个额外的连接器。 电池监控电路用于监控电池存储。 电池监控电路具有电源输入。 断开电路连接到电池存储器的正极端子,接地连接器,附加连接器和电池监控电路的电源输入端。 断开电路响应于附加连接器上的第一电压模式将电池监视电路的电力输入电连接到电池存储器的正极端子。 响应于附加连接器上的第二电压图案,断开电路将电池监视电路的电力输入与电池存储器的正极电连接。
