The embodiment of the invention discloses a battery charging control method and device, equipment, a medium and a vehicle, and the method controls the heating power and the charging power of a power battery based on the size relation between the allowable charging rate of the power battery and the charging rate provided for the power battery, and the ratio of the heating power to the charging power. As the allowable charging rate of the power battery changes along with the change of the charge state and the battery temperature of the power battery, namely, the change of the working condition, the distribution of the heating power and the charging power can be flexibly adjusted according to the actual working condition, so that the waste of the heating power caused by unreasonable setting of the temperature threshold value can be avoided; and the charging time is too long. Besides, when the allowable charging rate of the power battery is determined, the temperature and the state of charge of the power battery are considered, factors are more comprehensive, that is, the determined allowable charging rate is more accurate, and then the heating power and the charging power of the power battery can be more reasonably controlled.

    本申请实施例公开了一种电池充电控制方法、装置、设备、介质及车辆,本申请实施例是是基于动力电池的许用充电倍率和提供给动力电池的充电倍率的大小关系,以及加热功率和充电功率的占比,控制动力电池的加热功率和充电功率。因为动力电池的许用充电倍率随动力电池的荷电状态和电池温度,也即工况的变化而变化,因此可以根据实际工况灵活地调整加热功率和充电功率的分配,如此可以避免因温度阈值设置不合理而导致的加热功率浪费,充电时间过长等问题;此外,本申请实施例在确定动力电池的许用充电倍率时,考虑了动力电池的温度和荷电状态,因素更加全面,也即确定的许用充电倍率更准确,进而可以更合理的控制动力电池的加热功率和充电功率。
