The invention relates to a radial distance determination method and device, a vehicle and a storage medium, and relates to the field of battery management systems. The method comprises the steps that the temperature of a battery at the current moment and the current of the battery at the current moment are obtained, and therefore the radial distance, corresponding to the temperature of the current moment and the current of the current moment, at the current moment is determined based on the mapping relation. Wherein the mapping relation is the corresponding relation among the temperature, the current and the radial distance of the battery in the operation process, and the radial distance at the current moment is used for reflecting the difference value between the voltage value of the battery and the cut-off voltage of the battery and the electric quantity of the battery when the battery is at the temperature at the current moment and the current at the current moment. Therefore, the radial distance can be determined according to the mapping relation, so that the SOC value of the battery can be determined based on the radial distance, and the accuracy of the SOC value of the battery is improved.

    本申请涉及一种径向距离确定方法、装置、车辆及存储介质,涉及电池管理系统领域。该方法包括:获取电池在当前时刻的温度和电池在当前时刻的电流,从而基于映射关系,确定当前时刻的温度和当前时刻的电流对应的当前时刻的径向距离。其中,映射关系为电池在运行过程中的温度、电流与径向距离之间的对应关系,当前时刻的径向距离用于反映电池处于当前时刻的温度和当前时刻的电流时,电池的电压值与电池的截止电压之间的差值和电池的电量。由此,可以根据映射关系确定径向距离,以便基于径向距离确定电池的SOC值,从而提高电池的SOC值的准确性。
