The invention discloses a vehicle driving range prediction method and device, a storage medium and a vehicle. The method comprises the following steps: acquiring basic features, empirical mechanism features and model derivative features; determining in-mold features from the basic features, the empirical mechanism features and the model derivative features by using a feature selection model, and screening n important features from the in-mold features; predicting a first hundred kilometer energy consumption value in a future first time period according to the n important features by using a linear driving range prediction model; predicting a second hundred kilometer energy consumption value in a second time period in the future and a third hundred kilometer energy consumption value in a third time period in the future according to the in-mold characteristics by utilizing a nonlinear driving range prediction model; according to the first hundred-kilometer energy consumption value, the second hundred-kilometer energy consumption value and the third hundred-kilometer energy consumption value, a hundred-kilometer energy consumption predicted value of the vehicle is obtained, and the driving range of the vehicle is obtained by combining the battery SOE. By adopting the technical scheme of the invention, the prediction accuracy of the driving range of the vehicle can be improved.
