Zusammenfassung:	The invention provides an early warning method and system for a power battery of a new energy vehicle, which relate to the field of vehicle early warning, and aim to solve the technical problem of how to improve the accuracy of safety early warning of the power battery of the new energy vehicle. The method comprises the following steps of acquiringpower battery safety related data of vehicles connected with a big data platform, screening the power battery safety related data to obtain power battery temperature related data, power battery voltage related data and power battery insulation resistance related data, and performing neural network training on the screened data to establish a vehicle power battery safety prediction model, after the model is established, acquiring current power battery safety related data of a vehicle connected with the big data platform, and after the current power battery safety related data is substituted into the vehicle power battery safety prediction model, outputting a safety e
