    • In one embodiment, a rechargeable battery pack can be configured to power an electronic device having a first battery. The rechargeable battery pack can comprise a second battery supplemental to the first battery, an external power input configured to couple to an external power source, a power output for powering the electronic device. The rechargeable battery pack can also comprise a first circuit comprising a first power path between the external power input and the power output, a second power path between the second battery and the power output, and a power switch set. When the external power source is decoupled from the external power input, the first power path is disabled by the power switch set, and the second power path is enabled by the power switch set. When the external power source is coupled to the external power input, the first power path is enabled by the power switch set, and the second power path is disabled by the power switch set. Other examples and embodiments are described herein.
    • 在一个实施例中,可充电电池组可以被配置为为具有第一电池的电子设备供电。 可充电电池组可以包括补充到第一电池的第二电池,配置成耦合到外部电源的外部电力输入,用于为电子设备供电的功率输出。 可充电电池组还可以包括第一电路,其包括在外部电力输入和功率输出之间的第一电力路径,第二电池和电力输出之间的第二电力路径,以及电力开关组。 当外部电源与外部电源输入端分离时,第一个电源路径被电源开关设置禁用,第二个电源路径由电源开关组使能。 当外部电源耦合到外部电源输入时,通过电源开关组使能第一电源路径,并且通过电源开关组来禁用第二电源路径。 本文描述了其它示例和实施例。
