Overvoltage early warning method and device for new energy vehicle battery and electronic equipment

The invention belongs to the field of battery overvoltage early warning, and provides an overvoltage early warning method and device for a new energy vehicle battery and electronic equipment. According to the early warning method, on the basis of big data of a new energy vehicle battery, different time window lengths and interval durations are selected, the data are processed for iterative training of a neural network support vector machine model, so that an optimal neural network support vector machine model is obtained, the model is used, data of each time window length are input into the model, and the new energy vehicle battery early warning method is achieved. And according to calculation and output, whether the maximum voltage of the battery measurement single body exceeds the maximum threshold value after the future interval duration is judged, so that the effect of early warning the voltage of the battery measurement single body in advance is achieved, and the accuracy and timeliness of safety early w
