The present invention relates to a battery managing system of an electric motored vehicle which can diagnose an abnormal battery behavior using a cell balancing function, and a battery diagnosing method thereof. The battery managing system of the electric motored vehicle of the present invention comprises a processor which monitors a battery. The processor may perform primary cell balancing when a battery cell voltage deviation satisfies a cell balancing entry condition and determine whether an abnormal cell voltage deviation occurs after the primary cell balancing. If it is determined that the abnormal cell voltage deviation occurs, the processor can perform progressive voltage drop diagnosis using (N+1) order cell balancing.

    본 발명은 셀 밸런싱 기능을 활용하여 배터리의 이상 거동을 진단할 수 있는 전동화 차량의 배터리 관리 시스템 및 그의 배터리 진단 방법에 관한 것으로, 배터리를 모니터링하는 프로세서를 포함하고, 상기 프로세서는, 배터리 셀 전압 편차가 셀 밸런싱 진입 조건을 만족하는 경우 1차 셀 밸런싱을 수행하고, 상기 1차 셀 밸런싱 후 비정상 셀 전압 편차 발생 여부를 판단하고, 상기 비정상 셀 전압 편차 발생이 판단되면, (N+1)차 셀 밸런싱을 이용하여 진행성 전압 강하 진단을 수행할 수 있다.
