Electronic device and battery control method

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 at least one processor, comprising processing circuitry, individually and/or collectively, configured to control an overcharging protection operation voltage of the first battery cell and the second battery cell to a second specified voltage, wherein at least one processor, individually and/or collectively, is configured to; identify 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; accumulate the number of times of overcharging protection operation for a battery cell having a voltage higher than the second specified voltage, based on at least one voltage among the voltage of the first battery cell and the voltage of the second battery cell being greater than the second specified voltage; and set an overcharging protection operation voltage for a battery cell having a voltage greater than the second specified voltage as a third specified voltage less than the second specified voltage, based on the number of times of the overcharging protection operation for the battery cell having a voltage greater than the second specified voltage reaches a specified number of times.
