The invention relates to a state of charge determination method and device, a medium, a battery control system and a vehicle, and the method comprises the steps: controlling a first sub-battery pack and a second sub-battery pack to carry out the first power transfer, and then controlling the first sub-battery pack and the second sub-battery pack to carry out the second power transfer; the charge state of the first sub-battery pack is equal to the charge state of the second sub-battery pack, and the charge state when the charge state of the first sub-battery pack is equal to the charge state of the second sub-battery pack is determined as the charge state of the power battery. Therefore, the accurate charge state of the power battery can be obtained, the accurate charge state of the power battery can be obtained at any charge state stage of the power battery, a battery model does not need to be established, the workload is reduced, and time and resources are saved.

    本公开涉及一种荷电状态确定方法、装置、介质、电池控制系统和车辆,通过控制第一子电池包和第二子电池包之间进行第一次电量转移后,控制第一子电池包和第二子电池包之间进行第二次电量转移,以使第一子电池包的荷电状态和第二子电池包的荷电状态相等,并将第一子电池包的荷电状态和第二子电池包的荷电状态相等时的荷电状态确定为动力电池的荷电状态。从而能够得到较为准确的动力电池的荷电状态,且在动力电池的任意荷电状态阶段均能够得到准确的动力电池的荷电状态,且不需要建立电池模型,减少工作量,节约时间和资源。
