The invention provides a thermal runaway early warning method, device and system and electronic equipment, and the method comprises the steps: transmitting abnormal collection data to a server when a vehicle monitors an abnormal signal, and then extracting battery early warning data from the abnormal collection data through the server according to a preset battery state threshold value; according to the battery early warning data and the preset thermal runaway recognition model, thermal runaway diagnosis is carried out on the vehicle, a thermal runaway diagnosis result is obtained, and then the server can trigger thermal runaway early warning for the vehicle under the condition that the thermal runaway diagnosis result is that thermal runaway exists in the vehicle. Therefore, the calculation data volume of the server is reduced, the timeliness of thermal runaway early warning is improved, the risk caused by untimely thermal runaway treatment is avoided, the server can perform thermal runaway diagnosis on a plurality of vehicles at the same time, and full utilization of calculation resources is realized.

    本发明提供了一种热失控预警方法、装置、系统及电子设备,通过车辆在监测到异常信号时向服务器发送异常采集数据,随后服务器根据预设的电池状态阈值从异常采集数据中提取出电池预警数据,并根据电池预警数据以及预设的热失控识别模型对车辆进行热失控诊断,获得热失控诊断结果,随后服务器在热失控诊断结果为车辆存在热失控的情况下,能够针对车辆触发热失控预警。如此减少了服务器的计算数据量,提升了热失控预警的时效性,避免了因热失控处理不及时而造成的风险,并且,服务器能够同时对多个车辆进行热失控诊断,实现了计算资源的充分利用。
