A system for diagnosing abnormal battery cells is introduced. According to the present invention, the system includes: a cell voltage sensing part for measuring a voltage of each of a plurality of battery cells; a measurement part for measuring the number of battery cells in which an abnormal voltage sensed by the cell voltage sensing part is occurred; a determination part for determining an abnormality in the battery cells or cell voltage sensing part based on the number of battery cells in which an abnormal voltage measured by the measurement part is occurred; and a control part for controlling whether the battery is used or the operation of the battery cell in which the abnormal voltage is occurred depending on whether the battery cell is abnormal or the cell voltage sensing part is abnormal.

    본 발명에 따르면 복수의 배터리 셀의 전압을 각각 측정하는 셀전압센싱부; 셀전압센싱부에서 센싱한 전압 이상이 발생한 배터리 셀의 개수를 측정하는 측정부; 측정부에서 측정된 배터리 셀의 전압 이상이 발생한 개수를 기반으로 배터리 셀 또는 셀전압센싱부의 이상을 판단하는 판단부; 배터리 셀 이상 또는 셀전압센싱부의 이상 여부에 따라 배터리의 사용 여부 또는 전압 이상이 발생한 배터리 셀의 작동을 제어하는 제어부;를 포함하는 배터리 셀 이상 진단 시스템이 소개된다.
