The invention discloses a vehicle remaining mileage estimation method, a battery management system, a vehicle and a storage medium. The vehicle remaining mileage estimation method comprises the following steps: acquiring real-time working condition information and real-time battery information of the vehicle; obtaining a real-time residual electric quantity value and a real-time unit mileage value according to the real-time working condition information and the real-time battery information; determining that the real-time unit mileage value exceeds a set unit mileage value, and updating an energy consumption window and a unit mileage energy consumption value in a unit mileage energy consumption array which comprises a plurality of groups of historical unit mileage energy consumption values; and obtaining the remaining mileage of the vehicle according to the updated energy consumption window, the unit mileage energy consumption value in the energy consumption window and the real-time remaining electric quantity value. According to the vehicle remaining mileage estimation method, the battery management system and the vehicle, the remaining mileage is estimated based on the real-time data, the influence of the real-time driving behavior on the remaining mileage is considered, the real-time performance is achieved, and the estimation precision is improved.

    本发明公开了一种车辆剩余里程的估算方法和电池管理系统及车辆和存储介质,车辆剩余里程的估算方法包括:获取车辆的实时工况信息和实时电池信息;根据实时工况信息和实时电池信息获得实时剩余电量值和实时单位里程值;确定实时单位里程值超过设定单位里程值,更新单位里程能耗数组中的能耗窗口和单位里程能耗值,其中,单位里程能耗数组包括多组历史单位里程能耗值;根据更新后的能耗窗口、能耗窗口内的单位里程能耗值和实时剩余电量值获得车辆剩余里程。本发明的车辆剩余里程的估算方法和电池管理系统以及车辆,基于实时数据估算剩余里程,并且考虑实时驾驶行为对剩余里程的影响,具有实时性,提高了估算精度。
