The invention relates to a power battery charging method, device and equipment, a storage medium and a vehicle, and relates to the technical field of automobiles. The method is applied to the vehicle, the vehicle is provided with a power battery, and the method comprises the steps that the state of charge SOC of the power battery at the current moment is obtained; based on a preset charging reference relationship, determining a target charging path corresponding to the state of charge SOC at the current moment; determining the predicted temperature of the power battery at the next moment after the current moment based on the temperature and the charging current of the power battery at the current moment; and determining a target charging current corresponding to the next moment based on the target charging path and the predicted temperature of the power battery at the next moment, and charging the power battery at the next moment based on the target charging current. Therefore, the technical problems that the battery cell of the power battery needs to be replaced by a battery cell with a relatively high charging rate so as to realize rapid charging of the power battery by improving the charging rate, but the replacement of the battery cell can cause relatively high cost can be solved.
本申请涉及一种动力电池充电方法、装置、设备、存储介质及车辆,涉及汽车技术领域。应用于车辆,车辆设置有动力电池,该方法包括:获取动力电池在当前时刻的荷电状态SOC;基于预设充电基准关系,确定当前时刻的荷电状态SOC对应的目标充电路径;基于动力电池在当前时刻的温度以及充电电流,确定在当前时刻之后的下一时刻动力电池的预测温度;基于目标充电路径以及下一时刻动力电池的预测温度,确定下一时刻对应的目标充电电流,并在下一时刻基于目标充电电流对动力电池进行充电。由此,可以解决需要将动力电池的电芯替换为充电倍率较大的电芯,以实现通过提升充电倍率来进行动力电池的快速充电,但是,替换电芯会导致成本较大的技术问题。
