A method for diagnosing a battery pack including a plurality of battery cells is provided. According to the present invention, a battery management system detects voltages of the plurality of battery cells, respectively, and determines whether a difference between a maximum voltage and a minimum voltage among voltages of the plurality of battery cells is greater than a first threshold voltage. When the difference is greater than the first threshold voltage, the battery management system determines whether a first condition including a condition that a first battery cell in which the maximum voltage is detected and a second battery cell in which the minimum voltage is detected are adjacent battery cells is satisfied. When the first condition is satisfied, the battery management system determines that the diagnosis of the wiring shared between the first battery cell and the second battery cell is necessary.

    복수의 배터리 셀을 포함하는 배터리 팩의 진단 방법이 제공된다. 배터리 관리 시스템은 복수의 배터리 셀의 전압을 각각 감지하고, 복수의 배터리 셀의 전압 중에서 최대 전압과 최소 전압의 차이가 제1 임계 전압보다 큰지 판단한다. 차이가 제1 임계 전압보다 큰 경우, 배터리 관리 시스템은 최대 전압이 검출된 제1 배터리 셀과 최소 전압이 검출된 제2 배터리 셀이 인접한 배터리 셀인 조건을 포함하는 제1 조건을 만족하는지 판단한다. 제1 조건을 만족하는 경우, 배터리 관리 시스템은 제1 배터리 셀과 제2 배터리 셀이 공유하는 배선의 진단이 필요한 것으로 결정한다.
