The present invention relates to an abnormal battery cell detection method and system. It relates to an abnormal battery cell detection method and system that are configured to calculate the Z-score, Z-score slope, and delta Z-score of each battery cell using the average charge/discharge voltage of all battery cells, and detect abnormal battery cells based on these values. Thus, it is possible to detect the abnormal battery cells with improved speed and accuracy even in a situation where charge/discharge current is not constant.

    본 발명은 이상 배터리 셀 검출 방법 및 시스템에 관한 것으로, 전체 배터리 셀의 충방전 평균전압을 이용하여 배터리 셀들 각각의 Z-score, Z-score slope, delta Z-score를 연산하고, 이들 값을 기반으로 이상 배터리 셀을 검출하도록 구성되어, 충방전 전류가 일정하지 않은 상황에서도 향상된 속도 및 정확성으로 이상 배터리 셀을 검출할 수 있는 이상 배터리 셀 검출 방법 및 시스템에 관한 것이다.
