The invention is suitable for the technical field of automobiles, and provides a battery pack heat management method and device and a vehicle. The battery pack heat management method comprises the steps that the current environment temperature of a vehicle and the current initial temperature of a battery pack on the vehicle are obtained; acquiring the historical environment temperature of the vehicle in the same operation scene and the historical initial temperature of the battery pack in the same operation scene; acquiring a first control parameter for cooling the battery pack; comparing the current environment temperature with the historical environment temperature, comparing the current initial temperature with the historical initial temperature, and adjusting the first control parameter according to a comparison result to obtain a second control parameter; and performing thermal management on the battery pack according to the second control parameter. The embodiment of the invention can balance the cooling effect of the battery pack and the power consumption of the vehicle.
