The invention relates to the field of new energy vehicles, and provides a new energy vehicle endurance mileage management method and system. A battery attenuation coefficient is obtained based on automobile driving environment information, energy consumption parameters are obtained based on load, road surface and speed information, and initial endurance mileage and initial endurance time are obtained in combination with real-time battery capacity; calculating to obtain attenuated battery capacity and actual battery capacity according to the initial endurance time and the battery attenuation coefficient; and according to the actual battery capacity and the driving energy consumption parameter, calculating to obtain a corrected endurance mileage, and according to the position of the charging station, combining the corrected endurance mileage to obtain a management scheme. The technical problem that in the prior art, the adaptation degree of endurance management and the new energy automobile is low due to the fact that the endurance mileage management scheme of the new energy automobile is not highly attached to the actual driving condition of the automobile and the use condition of a battery is solved, and endurance management is carried out according to the actual driving condition and the driving environment of the new energy automobile. And the endurance management of the new energy vehicle and the vehicle adaptation degree are improved.
