The invention provides an electric vehicle battery cooling control method, device and equipment and a vehicle, and the method comprises the steps: detecting the current charging power, the current SOC and the current cell temperature of a battery in real time when the battery begins to be charged; obtaining a current core temperature threshold value according to the current charging power and the current SOC; and when the current cell temperature is greater than the current cell temperature threshold value, cooling the battery. By introducing the current charging power and the SOC of the battery into the core temperature threshold judgment of battery cooling, the battery cooling requirements under charging piles with different power in each charging stage in the charging process can be met, so that the battery cooling control is more flexible, the waste of cooling consumed energy during charging is reduced, and the charging speed is improved.

    本发明提供了一种电动汽车电池冷却控制方法、装置、设备及车辆,该方法包括:当电池开始充电时,实时检测所述电池的当前充电功率、当前SOC以及当前电芯温度;根据所述当前充电功率和当前SOC,获得当前芯温阈值;当所述当前电芯温度大于所述当前芯温阈值,对所述电池进行冷却;通过将电池的当前充电功率和SOC引入电池冷却的芯温阈值判断,可以满足充电过程中各充电阶段和不同功率的充电桩下的电池冷却需求,使得电池冷却控制更加灵活,减少充电时冷却消耗能量的浪费,提高充电速度。
