The invention provides a method and device for determining the state of charge of a battery, terminal equipment, a power battery and a vehicle. The method comprises the steps that operation data corresponding to all time points in the operation process of a target battery are acquired; judging whether the power value of the target battery at the preset moment is a peak power value or not according to the operation data; and if yes, determining the target charge state of the target battery according to the operation data and the peak power value. According to the scheme, the corresponding target charge state is determined according to the operation data in the operation process of the target battery, that is, the target charge state of the target battery can be determined in the operation process of the battery, so that the convenience of determining the charge state of the battery is improved.

    本申请提供一种电池荷电状态的确定方法、装置、终端设备、动力电池和车辆,方法包括:获取目标电池运行过程中各时间点对应的运行数据;根据各运行数据判断目标电池在预设时刻的功率值是否为峰值功率值;若是,则根据运行数据和峰值功率值确定目标电池的目标荷电状态。本方案是依据目标电池运行过程中的运行数据确定对应的目标荷电状态,即能够在电池运行过程中确定目标电池的目标荷电状态,因此提高了确定电池的荷电状态的便捷度。
