Abstract: An electronic device includes a system circuit, a power connector, a path selection circuit, a plurality of battery connectors, a plurality of series circuits, and a control circuit. The power connector is suitable for receiving power. The path selection circuit is coupled to the system circuit and the power connector. The battery connectors are respectively suitable for coupling a plurality of batteries. The series circuits respectively correspond to the battery connectors, and each series circuit is connected between the corresponding battery connector and the path selection circuit. Each series circuit includes: a charging switch, a battery switch and a discharging path. In a sequential discharge mode, the control circuit controls the series circuits to turn on the battery switch thereof in turn and controls the path selection circuit to connect the series circuits to the system circuit. The remaining battery switches and all charging switches remain off.

Abstract: An electronic device includes a battery, a battery gauge, and a processor. The battery is configured to supply power to the electronic device. The battery gauge is configured to gauge the battery to generate a plurality of remaining capacities a battery temperature, and a battery voltage of the battery. The processor is configured to sequentially read the plurality of remaining capacities. The processor determines whether a preset condition is met according to the battery temperature and the battery voltage in a case that a read remaining capacity is equal to a cut-off capacity and a read previous remaining capacity is greater than a preset capacity. The processor performs a capacity correction process in a case of determining that the preset condition is met. The capacity correction process includes using the read previous remaining capacity as a correction capacity and reporting the correction capacity to a system circuit.
