The invention relates to the technical field of power battery control and provides a power battery endurance mileage estimation system and method. The method comprises the steps: S1, reading the current electric quantity SOC of a power battery; S2, based on a recent driving behavior table, obtaining the driving mileage corresponding to each current set electric quantity interval; and S3, estimating the endurance mileage of the current electric quantity SOC based on the driving mileage corresponding to each current set electric quantity interval. The endurance mileage of the current electric quantity is estimated based on the driving mileage corresponding to each set electric quantity interval in the recent driving behavior; the influence of weather and battery aging degree on the endurancemileage of the electric power battery is comprehensively considered, for example, under the same condition, the endurance mileage of the same electric quantity in summer is lower than that in spring,and an air conditioner needs to be started in summer so that the accuracy of the endurance mileage of the electric quantity is improved.
本发明涉及动力电池控制技术领域,提供了一种动力电池续航里程估算系统及方法,方法包括:S1、读取动力电池当前电量SOC;S2、基于近期驾驶行为表获取当前各设定电量区间对应的行驶里程;S3、基于当前各设定电量区间对应的行驶里程预估当前电量SOC的续航里程。基于近期的驾驶行为中各设定电量区间对应的行驶里程来估算当前电量的续航里程,综合考虑了气候、电池老化程度对电动力电池续航里程的影响,例如相同条件下,相同电量在夏季的续航里程低于春季,因为夏季需要开空调,提高电量续航里程的精准度。
