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.

    本申请涉及新能源汽车领域,提供一种新能源汽车续航里程管理方法及系统。通过基于汽车行驶环境信息获得电池衰减系数,基于载重、路面和速度信息获得耗能参数,结合实时电池容量获得初始续航里程以及初始续航时间;根据初始续航时间和电池衰减系数计算获得衰减电池容量和实际电池容量;根据实际电池容量和行驶耗能参数计算获得修正续航里程,根据充电站位置结合修正续航里程获得管理方案。解决现有技术中存在新能源汽车的续航里程管理方案与车辆实际驾驶情况和电池使用状况贴合度不高,导致续航管理与新能源汽车适配度较低的技术问题,实现根据新能源汽车实际驾驶情况和驾驶环境进行续航管理,提高新能源汽车续航管理和车辆适配度的技术效果。
