본 실시예는 배터리의 내부 단락을 검출하는 방법 및 장치에 관한 것으로서, 더욱 상세하게는 배터리 셀의 전압 데이터만 사용해서 배터리 셀의 내부 단락을 정확하게 검출할 수 있는 기술에 관한 것이다.
The present embodiment relates to a method and a device for detecting an internal short circuit of a battery. More specifically, the present invention relates to a technology capable of accurately detecting the internal short circuit of a battery cell using only voltage data of the battery cell. The method for detecting the internal short circuit of the battery of the present invention comprises the following steps of: determining whether a first battery module is abnormal; electrically disconnecting the first battery module from a load or a charging device; obtaining a first open circuit voltage value of each of the plurality of battery cells; obtaining a second open circuit voltage value of each of the plurality of battery cells; and determining whether there is the internal short circuit of each of the plurality of battery cells.
