The invention relates to the technical field of vehicles, in particular to a battery thermal runaway prediction method and device, a vehicle and a storage medium, and the method comprises the steps: building a feature matrix of battery attributes of a current vehicle when the current vehicle is judged to meet a preset thermal runaway prediction condition, and inputting the characteristic matrix into a preset overheating prediction model to obtain a plurality of thermal risk probabilities of the battery of the current vehicle, calculating an average value of the plurality of thermal risk probabilities, and obtaining a thermal runaway prediction result of the current vehicle according to the average value of the plurality of thermal risk probabilities. Therefore, the problems that different overheat prediction models need to be established for adaptation for vehicle data under different conditions, meanwhile, nonlinear fitting of battery attribute internal factors and feature construction of external environment factors are lacked, and therefore the prediction accuracy of the overheat prediction models is affected are solved.
本申请涉及车辆技术领域,特别涉及一种电池热失控预测方法、装置、车辆及存储介质,其中,方法包括:经判断得到当前车辆满足预设的热失控预测条件时,建立当前车辆的电池属性的特征矩阵,并将特征矩阵输入至预设的过热预测模型得到当前车辆的电池的多个热风险概率,计算多个热风险概率的平均值,并根据多个热风险概率的平均值得到当前车辆的热失控预测结果。由此,解决了针对不同情况的车辆数据,需要建立不同的过热预测模型进行适配,同时缺乏对电池属性内部因素的非线性拟合以及外部环境因素的特征构造,从而影响过热预测模型预测的准确性等问题。
