The invention provides a new energy vehicle remaining driving mileage prediction method and system, relates to the field of new energy vehicle driving mileage prediction, and aims to solve the problem of how to improve the accuracy of new energy vehicle remaining driving mileage prediction. The method comprises the following steps: collecting discharge condition data of a plurality of vehicles through a big data platform, after a training target data set required by neural network training and a training input data set with high correlation with the remaining driving mileage of the vehicle are obtained through screening according to a preset condition, performing neural network training to establish a new energy vehicle remaining driving mileage prediction model; and obtaining current discharge condition data of the vehicle having a demand for the residual driving mileage prediction value, substituting the current discharge condition data into the new energy vehicle residual driving mileage prediction model, and calculating the residual driving mileage prediction value of the required vehicle. According to the invention, accurate residual driving mileage prediction can be obtained by establishing the vehicle residual driving mileage prediction model, and a driver can formulate a reasonable route plan according to the remaining driving mileage.
