The invention provides a method, system and device for estimating the remaining driving range of an electric vehicle, and the method comprises the steps: collecting the temperature of a battery, and obtaining the attenuation proportion of available power; calculating the residual available electricity quantity ET according to the available electricity quantity attenuation proportion; calculating the dynamic endurance remaining mileage according to the remaining available electricity quantity; the dynamic endurance remaining mileage calculation specifically comprises the steps that after the electric vehicle gets off the line, the initial power consumption per hundred kilometers is defaulted to be power consumption announced by CLTC-C, after the electric vehicle gets on the line, the comprehensive power consumption per hundred kilometers EC of the electric vehicle within a first preset distance is counted, and the calculation formula of the remaining mileage S is # imgabs0 #. And the comprehensive power consumption per hundred kilometers EC of the electric vehicle at the first preset distance is counted, and the remaining endurance mileage is calculated according to the comprehensive power consumption per hundred kilometers EC, so that the dynamic endurance mileage estimation is more accurate.
本发明提供了一种电动车辆剩余续驶里程估算方法、系统及装置,包括:采集电池温度,获取可用电量衰减比例;根据可用电量衰减比例计算剩余可用电量ET;根据剩余可用电量计算动态续航剩余里程;动态续航剩余里程计算具体包括:电动车辆下线后初始百公里电耗默认为CLTC‑C公告电耗,所述电动车辆上线后统计其在第一预设距离的综合百公里电耗EC,剩余里程S计算公式为:#imgabs0#本发明的技术方案,根据可用衰减比例来计算剩余可用电量,并且统计电动车辆在第一预设距离的综合百公里电耗EC,根据此来计算剩余续航里程,动态续航里程估算更精准。
