본 발명은 배터리 팩, 차량 및 이의 열폭주 모니터링 방법을 개시한다. 배터리 팩은 순차적으로 적층된 복수개의 단일셀을 포함하는 배터리 모듈; 단일셀의 적층 방향을 따라 배터리 모듈의 단부에 구비되는 엔드 플레이트; 엔드 플레이트와 평행하는 적어도 하나의 단일셀의 측면에 구비되어 단일셀의 팽창 변형값을 모니터링하는 모니터링 구조; 및 모니터링 구조와 전기적으로 연결되어, 팽창 변형값에 따라 변형률 및 기설정 시간 내의 변형 속도를 계산하고 변형률 및 변형 속도에 따라 배터리 팩(100)이 열폭주 상태인지를 판단하는 BMS를 포함한다.

    Disclosed in the disclosure is a battery pack, a vehicle, and a monitoring method for thermal runaway thereof. The battery pack includes: a cell set, including a plurality of single cells stacked in sequence; an end plate, provided along a stacking direction of the plurality of single cells on an end of the cell set; a monitoring structure, provided on at least one lateral surface that is parallel to the plurality of single cells and the end plate, configured to monitor an expansion deformation value of the plurality of single cells; a battery management system, BMS, electrically connected to the monitoring structure, configured to calculate a deformation rate and a deformation velocity in a preset time according to the expansion deformation value so as to determine whether the battery pack is in a thermal runaway state according to the deformation rate and the deformation velocity.
