The invention provides a thermal runaway alarm device and method, and belongs to the technical field of battery thermal runaway. The method comprises the steps that a thermal battery module supplies power to a battery management module after the temperature reaches a first threshold value and is activated, a first power management module is connected with a control module, and then the first power management module supplies power to the control module according to the power supply state of the thermal battery module; therefore, the control module gives a thermal runaway alarm when the temperature reaches the second threshold value, and the safety and reliability of lithium battery management are improved.

    本申请提供了一种热失控报警装置和方法,属于电池热失控技术领域。该方法包括:热电池模组在温度达到第一阈值被激活后向电池管理模块供电,第一电源管理模块与控制模块连接,进而通过第一电源管理模块根据热电池模组的供电状态为控制模块供电,从而使得控制模块在温度达到第二阈值时进行热失控报警,提高了对锂电池管理的安全性和可靠性。
