电子设备
摘要：
一种电子设备其包括电源单元、处理单元、电压取样电路及开关单元。电源单元给处理单元供电。电压取样电路用于对电源单元的供电电压进行取样，以产生取样电压。处理单元用于根据取样电压监控电源单元的电量。开关单元电性连接于电源单元与电压取样单元之间。处理单元用于在电子设备关机时产生第一控制信号，开关单元根据第一控制信号断开电源单元与电压取样电路之间的电性连接。
摘要（英）：

An electronic device comprises a power unit, a processing unit, a voltage sampling circuit and a switch unit. Electric power is supplied to the processing unit through the power unit. The voltage sampling circuit is used for sampling the power supply voltage of the power unit so that sampled voltage can be generated. The processing unit is used for monitoring the electric quantity of the power unit according to the sampled voltage. The switch unit is electrically connected between the power unit and the voltage sampling unit. The processing unit is used for generating a first control signal when the electronic device is stopped. The electric connection between the power unit and the voltage sampling circuit is cut off by the switch unit according to the first control signal.
