The embodiment of the invention provides a power battery fast charging control method and device, equipment and a storage medium. The power battery fast charging control method comprises the following steps: acquiring real-time characteristic parameters of a power battery, wherein the real-time characteristic parameters comprise at least two of a real-time battery cell temperature and a real-time charge state, a real-time working characteristic parameter of a thermal management component, and a real-time environment characteristic parameter of an environment where the power battery is located; and processing the real-time characteristic parameters by adopting a pre-trained reinforcement learning model to generate a first fast charging control instruction, the first fast charging control instruction comprising a first charging current control instruction for controlling fast charging current and/or a first thermal management control instruction for controlling the thermal management component. The reinforcement learning model is obtained by training according to multiple groups of sample data and the corresponding fast charge return value scores, so that by adopting the power battery control method provided by the embodiment of the invention, a control strategy lookup table does not need to be constructed for realizing accurate control of the fast charge of the battery, and the workload of the design and test stages of the power battery is reduced.

    本公开实施例提供一种动力电池快充控制方法、装置、设备和存储介质。动力电池快充控制方法包括:获取动力电池的实时特征参数,所述实时特征参数包括实时电芯温度和实时荷电状态,热管理部件的实时工作特性参数,以及所述动力电池所处环境的实时环境特征参数中的至少两个;采用预先训练的强化学习模型处理所述实时特征参数,生成第一快充控制指令,所述第一快充控制指令包括用于控制快充电流的第一充电电流控制指令和/或用于控制所述热管理部件的第一热管理控制指令。因为强化学习模型根据多组样本数据和对应的快充回报价值得分训练得到,所以采用本公开实施例提供的动力电池控制方法,无需为了实现电池快充的精确化控制而构建控制策略查找表,降低了动力电池设计和测试阶段的工作量。
