The invention provides a mileage prediction method and device for a new energy vehicle in a low electric quantity state. The method comprises the steps that when it is determined that the remaining electric quantity of a target vehicle is lower than a preset electric quantity threshold value, it is determined that the target vehicle is in a low-electric-quantity state; when the target vehicle is in the low-power state, first operation data, first battery state data and first environment data of the target vehicle are determined; inputting the first operation data, the first battery state data and the first environment data into a pre-established prediction model, so that the prediction model outputs a first predicted mileage of the target vehicle; wherein the prediction model is obtained based on historical data training of vehicles of the same type of the target vehicle, and the target vehicle is a new energy vehicle. According to the method, personalized and dynamic endurance mileage prediction for the low-power state of the new energy vehicle is realized, and the residual mileage prediction precision of the new energy vehicle in the low-power state is improved.
