The invention relates to the technical field of new energy automobile battery thermal runaway, and discloses a new energy automobile battery thermal runaway judgment and disposal method which comprises the following steps: (1) establishing a model database of battery thermal runaway volatile gas types; (2) monitoring the gas concentration change in the battery through a battery thermal runaway sensor; (3) according to the data detected by the thermal runaway sensor, judging whether to trigger the thermal runaway early warning of the battery; (4) comparing the gas concentration change within a certain time before the thermal runaway early warning is triggered with the model database; (5) judging the type of thermal runaway triggering according to a comparison result; and (6) taking a corresponding coping strategy according to thermal runaway triggering type feedback. The thermal runaway data is compared with the pre-stored data, the thermal runaway type is confirmed, and later treatment and maintenance are guided.

    本发明涉及新能源汽车电池热失控技术领域,公开了一种新能源汽车电池热失控判断处置方法,包括如下步骤:(1)建立电池热失控挥发气体类别的模型数据库;(2)通过电池热失控传感器监测电池内气体浓度变化;(3)根据热失控传感器检测的数据,判断是否触发电池热失控预警;(4)将热失控预警触发前的一定时间内的气体浓度变化与模型数据库进行比对;(5)根据比对结果判断热失控触发的类型;(6)根据热失控触发类型反馈,采取相应的应对策略。本发明通过热失控数据与预存数据进行比对,确认热失控类型,指导后期处置和维护。
