Title:
ELECTRONIC DEVICE AND BATTERY CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/234753
Kind Code:
A1
Abstract:
This electronic device may comprise: a first battery cell and a second battery cell connected in series to the first battery cell; a charging circuit configured to supply power of a first specified voltage from the outside to the first battery cell and the second battery cell; and a processor capable of controlling an overcharging protection operation voltage of the first battery cell and the second battery cell to a second specified voltage, wherein the processor: identifies the voltage of the first battery cell and the voltage of the second battery cell while the first battery cell and the second battery cell are charged using the power of the first specified voltage; accumulates the number of times of overcharging protection operation for a battery cell having a voltage higher than the second specified voltage, if at least one voltage among the voltage of the first battery cell and the voltage of the second battery cell is higher than the second specified voltage; and sets an overcharging protection operation voltage for a battery cell having a voltage higher than the second specified voltage as a third specified voltage that is lower than the second specified voltage, if the number of times of the overcharging protection operation for the battery cell having a voltage higher than the second specified voltage reaches a specified number of times.
