The invention discloses a power battery thermal runaway early warning method and system based on cloud data, and the method comprises the steps: collecting the data information of a power battery of a vehicle, and uploading the data information to a cloud platform; the cloud platform judges whether the power battery is in thermal runaway or not according to the power battery data information and generates cloud platform judgment result data information; synchronizing the judgment result data information of the cloud platform to a vehicle end; the method is simple to implement, and can reduce the probability of false report and missing report of thermal runaway events and improve the early warning accuracy of the thermal runaway of the power battery.

    本发明公开了一种基于云端数据的动力电池热失控预警方法及系统,其中,预警方法包括:采集车辆的动力电池数据信息,并上传至云平台;所述云平台根据所述动力电池数据信息判断动力电池是否热失控,并生成云平台判断结果数据信息;将所述云平台判断结果数据信息同步到车端;本发明实现简单,该方法可降低误报、漏报热失控事件概率,提高动力电池热失控预警准确性。
