The invention relates to a computer implemented-method for improving a lifetime of an electrical energy storage system (2) adapted for providing propulsion power for a vehicle (1), the method comprising: estimating (S102) a present state of health of the electrical energy storage system; determining (S104) vibration data (5) including mechanical vibration magnitude and vibration frequency spectrum of the electrical energy storage system; determining (S106) a degree of impact (S) of the vibrations of the electrical energy storage system on the state of health of the electrical energy storage system by processing the determined vibration magnitude and vibration frequency spectrum in a vibration-SOH model (10) adapted to infer a relationship between vibration magnitude and vibration frequency spectrum, and state of health, and adapting (S110) at least one vehicle control parameter (P) to vary at least one of the vibration magnitude and the vibration frequency to reduce the determining a degree of impact of the vibrations of the electrical energy storage system.
