The invention relates to the technical field of vehicles, in particular to an SOC estimation method and device of a single battery, a vehicle, a server and a storage medium, and the method comprises the steps: obtaining the battery data of a battery pack; the battery data of the battery pack is uploaded to a server, and the server identifies an identifier of a reference monomer of the battery monomers in the battery pack according to the battery data and calculates an initial state of charge (SOC) and monomer capacity of the reference monomer according to the battery data of the reference monomer; and determining a differential monomer in the battery pack according to the identifier of the reference monomer, calculating the SOC of the reference monomer at the target moment according to the initial SOC and the monomer capacity of the reference monomer, and calculating the SOC of the differential monomer at the target moment according to the SOC of the reference monomer at the target moment. Therefore, the problems that in the prior art, vehicle storage and operation are limited, the accuracy of SOC calculation of the single battery is low, the real-time state of the single battery is not obtained in time, the battery cannot be subjected to refined management and control, and the use experience is affected are solved.

    本发明涉及车辆技术领域,特别涉及一种电池单体的SOC估计方法、装置、车辆、服务器及存储介质,其中,方法包括:获取电池组的电池数据;上传电池组的电池数据至服务器,其中,服务器根据电池数据识别电池组中电池单体的参考单体的标识,并根据参考单体的电池数据计算参考单体的初始荷电状态SOC和单体容量;根据参考单体的标识确定电池组中的差异单体,根据参考单体的初始SOC和单体容量计算参考单体在目标时刻的SOC,并根据参考单体在目标时刻的SOC计算差异单体在目标时刻的SOC。由此,解决了相关技术中车辆存储和运算存在限制,对电池单体SOC计算的精确度较低,使得对电池单体的实时状态获取不及时,导致无法对电池精细化管控,影响使用体验等问题。
