摘要： 5 n7 An adapter for selectively connecting an external battery which is used as a power source of a portable notebook type computer to the computer or a charger, and an external battery system for controlling the connection between the adapter, the computer and the charger. The external battery is connectable to the adapter, and the adapter is connected to either the charger or the computer. A diode for selectively regulating either the direction for charging the external battery or the direction for introducing the power from the external battery is provided within the adapter. The adapter, the charger and the computer are selectively connected with each other by a common cable. There are three typical connection modes. In the mode A, the charger supplies a power to the computer. If the computer is being operated, the charger directly supplies a power of a constant voltage to the group of devices in the computer. If the computer is in an inoperative state, the charger supplies a power of a constant current for charging the internal battery. In the mode B, the charger charges the external battery through the adapter and outputs a power of a constant current. In the mode C, the power from the external battery is supplied to the computer through the adapter. The external battery is connected to the group of devices in parallel with the internal battery. Both batteries are operated in cooperation with each other. After the external battery is connected to the computer, the computer keeps on operating even if the internal battery is removed. Thus, it is unnecessary to back up the data in the computer.

摘要翻译： 用于将用作便携式笔记本型计算机的电源的外部电池选择性地连接到计算机或充电器的适配器，以及用于控制适配器，计算机和充电器之间的连接的外部电池系统。 外部电池可连接到适配器，适配器连接到充电器或计算机。 用于选择性地调节用于对外部电池充电的方向或者从外部电池引入电力的方向的二极管设置在适配器内。 适配器，充电器和计算机通过公共电缆选择性地相互连接。 有三种典型的连接方式。 在模式A中，充电器为电脑供电。 如果计算机正在运行，充电器将直接向计算机中的一组设备提供恒定电压的电源。 如果计算机处于非工作状态，充电器将提供恒定电流的电源，为内部电池充电。 在模式B中，充电器通过适配器为外部电池充电，并输出恒定电流。 在模式C中，外部电池的电源通过适配器提供给计算机。 外部电池与内置电池并联连接。 两个电池都是相互配合运作的。 将外部电池连接到电脑后，即使拆下内置电池，电脑也会继续运行。 因此，不需要备份计算机中的数据。
