The invention discloses a prediction method for driving mileage of an electric vehicle. The method comprises: calculating historical average endurance efficiency of an electric vehicle; calculating instant endurance efficiency of the electric vehicle; determining a current driving cycle interval of the electric vehicle according to the instant endurance efficiency; calculating working condition transition probability of the electric vehicle in a historical driving process; calculating instant expected endurance efficiency of the electric vehicle in a next phase according to the current driving cycle interval and the working condition transition probability; performing linear combination on the instant expected endurance efficiency of the electric vehicle in a next phase and the historical average endurance efficiency of the electric vehicle, and calculating a driving mileage predicted value by using the effective value of a power battery of the electric vehicle. The method can effectively predict driving mileage of electric vehicles.
