The invention relates to the technical field of electric bicycles, and discloses a mileage calculation method and system for an electric bicycle. The technical scheme of the invention comprises the following steps: constructing a battery performance analysis model, and collecting a battery performance coefficients in different use states through the battery performance analysis model; acquiring data point sets of a groups of residual electric quantity and residual mileage corresponding to the a battery performance coefficients; fitting the data point set of each group of residual electric quantity and residual mileage to generate a relation functions; and constructing a mapping relation between the a battery performance coefficients and the a relation functions so as to form a mileage calculation model, and a being greater than 0. The mileage of the electric bicycle is accurately calculated by comprehensively analyzing the influence factors of the battery performance.

    本发明涉及电动自行车技术领域,公开了一种电动自行车的里程计算方法和系统,本发明技术方案包括:构建电池性能分析模型,通过电池性能分析模型采集不同使用状态下的a个电池性能系数;获取a个电池性能系数下对应的a组剩余电量与剩余里程的数据点集;将每组剩余电量与剩余里程的数据点集分别进行拟合,生成a个关系函数;将a个电池性能系数与a个关系函数构建映射关系,从而形成里程计算模型,其中a>0。通过对电池性能影响因素的全面分析,从而对电动自行车的里程进行准确的计算。
