Abstract: An internal charging system controls charging of a battery used to power an electronic device when an external power source is connected to the device. The internal charging system can charge a battery that has a higher operating voltage than the voltage provided by the external power source. While charging the battery from the external power source, an internal charge controller can operate and inhibit functions of the device to indicate to user that a charging operation is commencing, and to prevent operation of the device when the battery voltage is too low to support such operation.

Abstract translation: 当外部电源连接到设备时，内部充电系统控制用于为电子设备供电的电池的充电。 内部充电系统可以对具有比外部电源提供的电压更高的工作电压的电池进行充电。 当从外部电源对电池充电时，内部充电控制器可以操作和禁止设备的功能，以向用户指示充电操作正在开始，并且当电池电压太低而不能支持时，防止设备的操作 操作。
