Charging/Discharging Circuit and Electronic Device

An electronic device, wherein the electronic device comprises a charging and discharging circuit and a battery pack, and the charging and discharging circuit is configured to charge and discharge the battery pack;

• and
• the charging and discharging circuit comprises a processing module, a first charging circuit, a first switch, a second switch, and an impedance, wherein the impedance comprises a path cabling impedance or a path device impedance between the battery pack and the charging and discharging circuit, wherein 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,
• wherein the first charging circuit is configured to:
• output a voltage by using the first port, wherein the voltage passes through the first switch, the second switch, wherein the impedance for charging the battery pack, wherein the first switch and the second switch are separately connected to a charging line of at least one battery in the battery pack, and
• wherein the processing module is configured to:
• obtain a voltage or a current of the charging line of the at least one battery in the battery pack, and control, based on the voltage 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.
