BATTERY CONTROL CIRCUIT, BATTERY AND ELECTRONIC DEVICE
DRIVE
November 22, 2023
This application provides a battery control circuit, a battery (10), and a related electronic device. The battery control circuit is connected in parallel between a positive electrode and a negative electrode of a battery pack (101). The battery control circuit includes a first inductor (L1), a first switch (S1), a second switch (S2), a first diode (D1), and a second diode (D2). A first terminal of the first switch and a cathode of the first diode are both coupled to the positive electrode of the battery pack, and a second terminal of the first switch is coupled to a terminal of the first inductor and a cathode of the second diode. An anode of the first diode is coupled to another terminal of the first inductor and a first terminal of the second switch, and a second terminal of the second switch and an anode of the second diode are both coupled to the negative electrode of the battery pack. The first switch and the second switch are simultaneously turned on or turned off. During implementation of this application, charging and discharging may be implemented by using energy of the battery pack. Currents of charging and discharging both generate Joule heat on an internal resistance of the battery pack to heat the battery. Therefore, heating efficiency is high.
