Usage of vibration data for route planning and extending battery pack lifetime

A computer-implemented method for establishing map relating geographical location to vibration health impact on electrical energy storage systems adapted for providing propulsion power for a vehicle, the method comprising:

• estimating, by a control unit, a present state of health of the electrical energy storage system;
• determining, by the control unit, mechanical vibration magnitude and vibration frequency spectrum of the electrical energy storage system;
• determining, by the control unit, location data indicating a location of the vehicle in a geographical area at which the mechanical vibration magnitude and vibration frequency spectrum of the electrical energy storage system occurred,
• determining, by the control unit, 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;
• accessing, by the control unit, a map database having stored geographical locations with associated degrees of impact on the state of health of electrical energy storage systems, and
• updating, by the control unit, the map database with the location data and the associated degree of impact at the location.
