    • An electronic device includes a first rechargeable battery, a solar cell mounted on the electronic device, a second rechargeable battery and a power management circuit. The power management circuit includes a control module, a DC/DC module, a switch and a power supply switching module. The DC/DC module is configured for converting the DC power generated by the solar cell from one voltage level to another, and activating and maintaining the activation of the control module. The switch is turned on by the control module when the control module is activated, causing the DC power from the DC/DC module to charge the second rechargeable battery. The power supply switching module is controlled by the control module to select the second rechargeable battery to power the electronic device if the voltage level of the rechargeable battery is lower than that of the second rechargeable battery.
    • 电子设备包括第一可充电电池,安装在电子设备上的太阳能电池,第二可充电电池和电源管理电路。 电源管理电路包括控制模块,DC / DC模块,开关和电源开关模块。 DC / DC模块被配置为将由太阳能电池产生的直流电力从一个电压电平转换到另一个电压电平,并且激活和维持控制模块的激活。 当控制模块被激活时,开关由控制模块接通,导致来自DC / DC模块的DC电源对第二个可充电电池充电。 如果可再充电电池的电压低于第二可充电电池的电压,则电源开关模块由控制模块控制以选择第二可充电电池来为电子设备供电。
