The invention relates to an endurance mileage calculation method and device, an electric vehicle and a computer storage medium, and belongs to the technical field of battery management.The endurance mileage calculation method comprises the steps that first estimated energy consumption and actual energy consumption of the vehicle in the last unit mileage are obtained; the running state of the vehicle-mounted energy consumption system in the previous unit mileage is obtained, and the energy consumption influence factor of the vehicle under the running state of the vehicle-mounted energy consumption system is calculated in combination with the estimated energy consumption and the actual energy consumption; and obtaining the residual energy of the vehicle-mounted power battery and the second estimated energy consumption of the vehicle in each unit mileage on the subsequent driving road, and calculating the endurance mileage of the vehicle in the running state of the vehicle-mounted energy consumption system based on the residual energy, the second estimated energy consumption and the energy consumption influence factor. In the calculation of the endurance mileage of the vehicle, the influence of the running state of the vehicle-mounted energy consumption system and the vehicle running road on the actual energy consumption of the vehicle is fully considered, and the accuracy of the calculation of the endurance mileage is ensured.

    本发明涉及一种续航里程计算方法、装置、电动车辆及计算机存储介质,属于电池管理技术领域,其中,该续航里程计算方法包括:获取车辆在上一单位里程的第一预估能耗和实际能耗;获取车载能耗系统在上一单位里程的运行状态,并结合预估能耗和实际能耗计算车载能耗系统在该运行状态下车辆的能耗影响因子;获取车载动力电池的剩余能量及车辆在后续行驶道路中每一单位里程的第二预估能耗,基于剩余能量、第二预估能耗及能耗影响因子计算车载能耗系统在该运行状态下车辆的续航里程。本发明在对车辆续航里程的计算中,充分考虑了车载能耗系统的运行状态和车辆行驶道路对车辆实际能耗的影响,保证续航里程计算的准确性。
