The invention provides a thermal runaway early warning device and system.The device comprises a conductive branch used for being connected with a battery management system, and the battery management system is configured to monitor whether the conductive branch is conducted or not; the early warning part and the conductive branch are arranged at intervals, the early warning part is configured to be connected with a to-be-monitored device, and when the temperature of the to-be-monitored device is larger than or equal to the preset temperature, the volume of the early warning part is deformed, so that the early warning part is connected with the conductive branch, and the conductive branch is conducted. According to the thermal runaway early warning device, thermal runaway early warning is achieved through a mechanical structure, a temperature collecting device does not need to be used, and the cost of the whole early warning device is reduced.

    本申请提供一种热失控预警装置和系统,所述装置包括导电支路,用于与电池管理系统连接,所述电池管理系统被配置为监测所述导电支路是否导通;预警部,与所述导电支路间隔设置,被配置为与待监测装置连接,当所述待监测装置的温度大于或等于预设温度时,所述预警部的体积发生形变使所述预警部与所述导电支路连接,以使所述导电支路导通。本热失控预警装置通过机械结构来实现热失控预警,无需使用温度采集装置,降低了整个预警装置的成本。
