Document Type and Number:
WIPO Patent Application WO/2024/029741
Kind Code:
A1
Abstract:
An electronic device, according to an embodiment, may comprise: an interface to be connected to a charger; a charging circuit connected to the interface through a first node; a PMIC connected to the charging circuit through a second node that is different from the fist node; and a switching circuit. The switching circuit may include a first switch for connecting an anode of a first battery cell and the first node to each other on the basis of a control signal from the processor. The switching circuit may include a diode including an anode connected to a cathode of the first battery cell, and a cathode connected to an anode of a second battery cell. The switching circuit may include a second switch for connecting the anode of the first battery cell and the second node to each other in another state different from a state in which the connection has been established by the first switch.
