The invention provides an electric vehicle fire early warning method and device. The method comprises the steps of taking vehicle data as the input of each prediction model obtained through pre-training, and obtaining the highest temperature of a single battery, the lowest temperature of the single battery and the current of a battery pack, which are output by the prediction model, and analyzing the highest temperature of the single battery, the lowest temperature of the single battery and the battery pack current by utilizing a preset fire judgment rule, determining whether the electric vehicle is about to be on fire, and if so, outputting fire early warning information. Since whether the electric vehicle is about to be on fire or not is determined according to the temperature and the current predicted by the prediction model after a period of time, the phenomenon that the electric vehicle is about to be on fire can be predicted for a long time in advance, and the use safety of the electric vehicle is improved.
本发明提供了一种电动汽车起火预警方法及装置,方法包括将车辆数据作为预先训练得到的各个预测模型的输入,得到预测模型输出的单体电池最高温度、单体电池最低温度和电池包电流;利用预设的起火判定规则,对单体电池最高温度、单体电池最低温度和电池包电流进行分析,确定电动汽车是否将要起火,若是,则输出起火预警信息。由于在确定电动汽车是否将要起火时,是利用的预测模型预测的一段时间后的温度和电流,因此,可以提前较长时间预测到电动汽车将要起火,提升了电动汽车使用的安全性。
