The invention relates to the technical field of vehicles, and discloses a battery SOC correction method and device, a storage medium, battery equipment and a vehicle, and the battery SOC correction method comprises the steps: obtaining the SOC of a battery at the current moment, a voltage error and a model SOC of a battery equivalent circuit; determining the SOC error of the battery according to the voltage error; determining the correction amount of the SOC at the current moment according to the SOC at the current moment, the SOC error and the model SOC; and determining the SOC of the battery at the next moment according to the SOC at the current moment, the correction of the SOC at the current moment and the power consumption of the battery between the current moment and the next moment. Therefore, the SOC estimation precision and the system robustness can be remarkably improved, rapid and accurate correction of the SOC in dynamic driving is realized, the service life of the battery is prolonged, and the overall performance is improved.

    本发明涉及车辆技术领域,并公开了一种电池SOC的修正方法和装置、存储介质、电池设备、车辆,其中,电池SOC的修正方法包括:获取电池的当前时刻SOC、电压误差和电池等效电路的模型SOC;根据电压误差确定电池的SOC误差;根据当前时刻SOC、SOC误差和模型SOC确定当前时刻SOC的修正量;根据当前时刻SOC、当前时刻SOC的修正量和电池在当前时刻至下一时刻之间的耗电量确定电池的下一时刻SOC。由此,可以显著提升SOC估算精度与系统鲁棒性,实现动态行车中SOC的快速准确修正,延长电池寿命并提升整体性能。
