Provided are a battery management system for performing a fault diagnosis to improve reliability, and an operation method thereof. According to the present invention, the battery management system comprises: a sensing/balancing circuit for monitoring a voltage, a current or a temperature of a battery cell and determining whether an overvoltage of the battery cell is true or false when the voltage of the battery is the overvoltage; and a relay control circuit for blocking a relay switch when the overvoltage is true.

    본 발명에 따른 배터리 관리 시스템은, 배터리 셀의 전압, 전류, 혹은 온도를 모니터링하고, 상기 배터리 셀의 전압이 과전압일 때 상기 과전압이 진성인지 가성인지를 판별하는 센싱/밸런싱 회로, 및 상기 과전압이 진성일 때, 릴레이 스위치를 차단시키는 릴레이 제어 회로를 포함할 수 있다.
