The invention provides a battery cooling control method, device and equipment and a vehicle, and the scheme comprises the following steps: firstly, predicting the predicted duration of the vehicle from the current position to the final position, obtaining the temperature rise rate of a battery, then determining the predicted temperature of the battery when the vehicle reaches the final position based on the temperature rise rate of the battery and the predicted duration, and calculating a predicted temperature difference between the battery predicted temperature and the battery cooling starting temperature, and controlling the output power of the battery cooling system based on the predicted temperature difference, so that the output power of the battery cooling system is dynamically adjusted along with the predicted temperature difference, thereby reducing the energy consumption of the battery cooling system, reducing the power consumption of the battery, and improving the battery cooling efficiency. And the endurance of the vehicle is improved. Compared with a battery cooling system adopting fixed output power in the prior art, the battery cooling system disclosed by the scheme has the advantages that the energy consumption is lower, and the electric quantity consumption of the battery is lower.
