The present disclosure relates to a thermal runaway detection system that comprises a venting device (55) with sealing bodies (551, 552, 553) disposed in a venting passage (555). The sealing bodies (551, 552, 553) are configured to close the venting passage (555) in a first position and is configured to open the venting passage (555) in a second position. The thermal runaway detection system further comprises a thermal runaway detection circuit (60) that is configured for monitoring the positions of the sealing bodies (551, 552, 553) and for outputting signals corresponding to the positions. The thermal runaway detection circuit (60) comprises a first detection node (63) connected to the venting device (55) and a second detection node (64) connected to the venting device (55), wherein a conductible path between the first detection node (63) and the second detection node (64) is set conductive via the sealing bodies (551, 552, 553) in one of the first position and the second position, and a controller (60) is configured to detect the conductivity of the conductible path and also configured to output a signal corresponding to the conductivity of the conductible path.

    본 개시는 배기 통로(555)에 배치된 실링 바디(551, 552, 553)를 갖는 배기 장치(55)를 포함하는 열 폭주 검출 시스템에 관한 것이다. 여기서, 실링 바디(551, 552, 553)는 제1 위치에서 배기 통로(555)를 폐쇄하도록 구성되고, 제2 위치에서 배기 통로(555)를 개방하도록 구성된다. 열 폭주 검출 시스템은 실링 바디(551, 552, 553)의 위치를 모니터링하고 그 위치에 대응하는 신호를 출력하도록 구성된 열 폭주 검출 회로(60)를 더 포함한다. 열 폭주 검출 회로(60)는 배기 장치(55)에 연결된 제1 검출 노드(63) 및 배기 장치(55)에 연결된 제2 검출 노드(64)를 포함하며, 여기서 제1 검출 노드(63) 및 제2 검출 노드(64)는 제1 위치 및 제2 위치 중 어느 하나에서 실링 바디(551, 552, 553)를 통해 전도상태로 설정되고, 제어기(65)는 전도성 경로의 전도성을 검출하고, 또한 전도성 경로의 전도성에 해당하는 신호를 출력하도록 구성된다.
