Beschreibung
Zusammenfassung:	An electronic device according to various embodiments may include: a battery cell that supplies power; at least one battery protection circuit connected to the battery cell; a battery pack including the battery cell and at least one battery protection circuit; and a processor operatively connected to the battery pack. The processor may be set to: perform monitoring until a voltage of the battery pack reaches a preset first voltage or higher when the battery pack is charged by an external power source; measure the number of occurrences of voltage fluctuations above a specified set value of the voltage of the battery pack in the monitoring process; determine the voltage range of the battery cell based on the measured voltage of the battery pack and the number of voltage fluctuations; and predict the voltage of the battery cell based on the voltage range of the battery cell. The charge blocking operation can be performed more accurately. 다양한 실시예에 따른 전자 장치는 전력을 공급하는 배터리 셀(cell), 배터리 셀과 연결된 적어도 하나 이상의 배터리 보호 회로, 배터리 셀 및 적어도 하나 이상의 배터리 보호 회로를 포함하는 배터리 팩(pack), 배터리 팩과 작동적으로(operatively) 연결된 프로세서를 포함할 수 있다. 프로세서는 외부 전원에 의해 배터리 팩이 충전되는 경우, 배터리 팩의 전압이 미리 설정된 제1전압 이상이 될 때까지 모니터링하고, 모니터링 과정에서 배터리 팩의 전압의 지정된 설정 값 이상의 전압 변동 발생 횟수를 측정하고, 측정된 배터리 팩의 전압, 전압 변동 발생 횟수에 기초하여 배터리 셀의 전압 구간을 판단하고 및 배터리 셀의 전압 구간에 기초하여 배터리 셀의 전압을 예측하도록 설정될 수 있다.
