The invention relates to an electric motorcycle and an SOC determination method of a battery of the electric motorcycle. The method comprises the following steps: acquiring a current SOC measured value of a motorcycle battery at a current time point; acquiring a historical SOC error interval of a historical SOC measurement value at a previous moment, wherein a historical SOC measurement upper limit value and a historical SOC measurement lower limit value of the historical SOC error interval are determined based on a fitting function relationship between a plurality of SOC measurement values and a plurality of corresponding SOC errors; and correcting the current SOC measured value based on the relationship between the current SOC measured value and the historical SOC error interval. According to the method and the device, the technical problem that the accuracy of the SOC of the battery is not high due to the fact that the current SOC measurement value is calculated only through linear interpolation is solved, so that the accuracy of electric quantity evaluation of the battery of the electric motorcycle is improved, and then the accuracy of endurance evaluation of the electric motorcycle by a user is improved.

    本申请涉及一种电动摩托车及其电池的SOC确定方法。所述方法包括:获取摩托车电池在当前时间点的当前SOC测量值;获取前一时刻的历史SOC测量值的历史SOC误差区间,所述历史SOC误差区间的历史SOC测量上限值以及历史SOC测量下限值基于多个SOC测量值与对应的多个SOC误差的拟合函数关系确定;基于所述当前SOC测量值与所述历史SOC误差区间的关系,对所述当前SOC测量值进行修正。通过本申请,解决了仅通过线性插值计算当前SOC测量值导致的电池SOC准确度不高的技术问题,从而提高了电动摩托车电池的电量评估的准确性,进而提高了用户对电动摩托车续航评估的准确性。
