The embodiment of the invention provides a battery thermal runaway detection system and method, and relates to the field of battery temperature detection. The battery thermal runaway detection system comprises a data processing module and a temperature data acquisition module, the temperature data acquisition module comprises a plurality of thermocouples, the temperature acquisition ends of at least two of the thermocouples are electrically connected with the data processing module, and the temperature measurement ends of at least two of the thermocouples are electrically connected. The temperature measurement end of each thermocouple is close to the explosion-proof valve in the battery module, and the plurality of thermocouples and the data processing module form at least one temperature detection loop; and the data processing module is used for calculating temperature information according to a detection signal of the temperature acquisition end, and judging that the battery module is subjected to thermal runaway when the temperature information reaches a preset value. The temperature of the battery module is detected in real time by using a temperature detection loop formed by the plurality of thermocouples and the data processing module so that the detection timeliness rate of the thermal runaway of the battery module is improved.
Description
Technical field [0001] The present invention relates to a battery temperature detection field, in particular, it relates to a system and method for detecting a battery thermal runaway. Background technique [0002] Current battery system for thermal runaway manner generally using an aerosol, smoke, hydrogen, and air pressure sensors, in the case of thermal runaway of the battery system, the battery uncontrolled release of smoke, hydrogen gas, and alkanes, such case above gas sensor will be detected and an alarm. [0003] However, when using the sensors mentioned above, required the use of chip components of the respective detection principle more complicated, reliability to be verified. On the other hand, if a smaller temperature sensitive device detects the capacity of the battery thermal runaway situation, since the small amount of gas is released, it will cause the temperature sensitive device can not detect the temperature changes in time of the battery, causing the battery c...
