The invention relates to a battery thermal runaway prediction method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring historical state data of a to-be-monitored battery at the previous moment and current state data of the to-be-monitored battery at the current moment, and fusing an initial thermal runaway prediction result obtained by the historical state data and a current thermal runaway prediction result obtained according to the initial thermal runaway prediction result and the current state data, and obtaining a target thermal runaway prediction result. According to the method, different from a scheme of performing thermal runaway early warning according to the current state data of the battery in the traditional technology, thermal runaway early warning is performed in combination with two dimensions of the historical state and the real-time state of the battery, so that the situation of misinformation caused by sampling misinformation, dramatic change of external working conditions and the like can be filtered, and the accuracy of thermal runaway early warning is improved. And the false alarm rate of battery thermal runaway prediction is reduced.

    本申请涉及一种电池热失控预测方法、装置、计算机设备和存储介质。所述方法包括:获取待监测电池上一时刻的历史状态数据和当前时刻的当前状态数据,将由历史状态数据得到的初始热失控预测结果、以及根据初始热失控预测结果和当前状态数据得到的当前热失控预测结果进行融合,得到目标热失控预测结果。上述方法,区别于传统技术中根据电池的当前状态数据进行热失控预警的方案,而是结合电池的历史状态和实时状态两个维度进行热失控预警,能够过滤掉因采样误报和外部工况剧烈变化等情况导致误报的情况,降低电池热失控预测的误报率。
