The invention provides a power determination method and device for a power battery, equipment and a storage medium, and the method comprises the steps: obtaining first state data of the power battery if a vehicle is in a driving working condition; determining first available power of the power battery according to the first state data and a power mapping table; determining second state data of the power battery according to the first state data, model parameters of the equivalent circuit corresponding to the power battery and the state data of the power battery; and performing correction processing on the first available power based on the second state data and a preset power correction parameter to obtain a first target available power of the power battery. The first available power is corrected through the second state data and the preset power correction parameter, and the influence of the second state data of the power battery in the actual use process on the maximum available power is considered, so that the obtained first target available power is close to the actual power capability of the power battery; and the safety and the dynamic property of vehicle driving are ensured.

    本申请提供一种动力电池的功率确定方法、装置、设备和存储介质,该方法包括:若车辆处于行车工况,获取动力电池的第一状态数据;根据第一状态数据和功率映射表,确定动力电池的第一可用功率;根据第一状态数据、动力电池对应等效电路的模型参数和动力电池的状态数据之间的对应关系,确定动力电池的第二状态数据;基于第二状态数据和预设功率修正参数对第一可用功率进行修正处理,得到动力电池的第一目标可用功率。通过第二状态数据和预设功率修正参数对第一可用功率进行修正处理,考虑了动力电池在实际使用过程中的第二状态数据对最大可用功率的影响,从而使得获得的第一目标可用功率接近动力电池实际功率能力,保证车辆行驶的安全性和动力性。
