Abstract: A method for predicting service life of a battery unit previously used within at least one first application, the method comprising: assessing a battery capacity of the battery unit at an end of a first service life of the battery unit within the at least one first application, identifying a suitable second application for the battery unit by comparing the assessed battery capacity to given power requirements of at least one suggested second application, obtaining ageing data indicative of battery ageing of the battery unit in its at least one first application, predicting an expected second service life of the battery unit in the identified second application based on at least information relating to a planned usage of the battery unit in the second application and on the obtained ageing data from the at least one first application.

Abstract: A method for monitoring battery ageing of a battery unit in an energy storage system of a vehicle or vessel. The method includes predicting an expected service life of the battery unit based on at least information relating to a planned usage of the battery unit, during usage of the battery unit, obtaining operational data relating to an actual usage of the battery unit, predicting an actual service life of the battery unit based on at least the obtained operational data, comparing the predicted actual service life with the predicted expected service life, thus obtaining a comparison result; determining whether a predetermined notification criterion is fulfilled based on the comparison result, generating a notification to a user of the battery unit at least if the predetermined notification criterion is fulfilled.
