The invention discloses controlling battery pack vibration using vibration data and SOH feedback. Specifically, the invention relates to a computer-implemented method for improving the life of an electrical energy storage system (2) adapted to provide propulsion power for a vehicle (1), the method comprising: estimating (S102) a current state of health of the electrical energy storage system; determining (S104) vibration data (5) comprising a mechanical vibration amplitude and a vibration spectrum of the electrical energy storage system; determining (S106) a degree of influence (S) of the vibration of the electrical energy storage system on the state of health of the electrical energy storage system by processing the determined amplitude of vibration and the frequency spectrum of vibration in a vibration-SOH model (10) adapted to infer a relationship between the amplitude of vibration and the frequency spectrum of vibration and the state of health; and adapting (S110) at least one vehicle control parameter (P) to vary at least one of the vibration amplitude and the vibration frequency to reduce the determined degree of influence of the vibration of the electrical energy storage system.
