Usage of vibration data and soh feedback for controlling battery pack vibration

Abstract

A computer implemented-method for improving a lifetime of an electrical energy storage system adapted for providing propulsion power for a vehicle is provided. The method includes estimating a present state of health of the electrical energy storage system; determining vibration data including mechanical vibration magnitude and vibration frequency spectrum of the electrical energy storage system; determining a degree of impact 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 adapted to infer a relationship between vibration magnitude and vibration frequency spectrum, and state of health, and adapting at least one vehicle control parameter 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.
