Abstract: An electronic system includes a first device and a second device is provided. The first device includes a power connector, a first connector, a first battery, and a charging controller. The second device includes a second connector and a second battery. The power connector is configured to receive an external voltage. The first battery is electrically connected to the power connector and the first connector. The charging controller is electrically connected to the power connector and the first battery. The second connector is utilized for connecting the first connector. The second battery is electrically connected to the second connector. When the first connector is connected to the second connector, the charging controller selectively connects the first battery and the second battery in a series via the first connector and the second connector according to the level of the first battery and the second battery.

Abstract: A power module adapted to a computer system is provided in the disclosure. The power module includes three batteries, a first voltage output terminal, a second voltage output terminal, a third voltage output terminal, and a charging/discharging control unit. The charging/discharging control unit determines a quantity of serially connected batteries based on a load signal of the computer system, to supply a first voltage to the first voltage output terminal, a second voltage to the second voltage output terminal, or a third voltage to the third voltage output terminal. The first voltage, the second voltage, and the third voltage correspond to different quantities of batteries. The disclosure further provides a power supply method.
