The embodiment of the invention provides a battery temperature prediction method and device, a vehicle and a storage medium, and can predict the temperature change of a battery based on the real-time change of the power of the battery on a navigation route after the driving route is determined, thereby obtaining a more accurate battery temperature prediction value. The battery temperature prediction method comprises the following steps: acquiring a real-time power change curve of a navigation route for driving to a destination; acquiring first real-time state information of the battery at the T1 moment; obtaining a first real-time current; based on the first real-time current, determining a first temperature variation of the battery at the moment T1 to T2; obtaining a temperature prediction value at the T2 moment; determining a second real-time voltage of the battery at the T2 moment based on the first real-time current; obtaining a second real-time current; based on the second real-time current, determining a second temperature variation of the battery at the moment T2 to T3; and by parity of reasoning, the temperature prediction value at the T3 moment is obtained, and the temperature prediction value at the Tn moment is obtained.
