Zusammenfassung: | This application discloses a charging/discharging circuit and an electronic device. The charging/discharging circuit is configured to charge and discharge a battery pack, the charging/discharging circuit includes a processing module, a first charging circuit, a first switch, a second switch, and an impedance. The impedance includes a path cabling impedance and a path device impedance between the battery pack and the charging/discharging circuit. The first switch and the second switch are separately connected to the processing module, a first port of the first charging circuit, and the battery pack. The first charging circuit is configured to output a voltage by using the first port. The voltage passes through the first switch, the second switch, and the impedance for charging the battery pack. The processing module is configured to obtain a voltage and/or a current of a charging line of each battery in the battery pack, and control, based on the voltage and/or the current, the first switch and the second switch to be turned on or turned off, so that batteries in the battery pack are charged equally, thereby preventing a case that one battery is fully charged with power, but the other battery is not fully charged. |
