The invention discloses a vehicle electric driving mileage prediction method, system and device and a storage medium, and the method comprises the steps: obtaining the navigation planning information of a target vehicle, obtaining the three-dimensional map information of a corresponding planned path according to the navigation planning information, and determining the space height information of each path point on the planned path according to the three-dimensional map information; dividing the planned path according to the spatial height information to obtain a plurality of three-dimensional road sections, and determining three-dimensional path information of each three-dimensional road section; inputting the three-dimensional path information into a pre-trained driving energy consumption prediction model, and predicting to obtain first driving energy consumption of each three-dimensional road section; current first residual electric energy of the target vehicle is obtained, and the residual mileage of the target vehicle is predicted according to the first residual electric energy and the first driving energy consumption. The method improves the prediction accuracy of the electric drive remaining mileage of the vehicle, avoids the influence on user travel caused by the inaccurate remaining mileage, improves the travel experience of the user, and can be widely applied to the technical field of new energy vehicles.
