Abstract: A method for determining a state of health of a rechargeable battery includes: determining a change in charge within an upper border and a lower border of a charging state window, the change in charge being determined by summing up current values measured within the charging state window; determining an actual state of health by scaling the change in charge with the width of the charging state window and dividing by an initial charging capacity of the battery; and determining an average state of health by calculating a sliding average of the actual state of health with at least one previous determined state of health.

Abstract: A battery management system for a rechargeable battery is disclosed which includes a control system configured to control, a numerical battery model, including a parametrized electric model; a parametrized thermal model; an aging model configured to provide stress parameters indicative of an instantaneous consumption of an expected lifetime of the battery in dependence on an internal temperature of the battery, and one or more of momentary state of charge, current, voltage and power delivered; updated electric parameters and/or updated thermal parameters based on a chronological sequence of internal temperature as obtained from the parametrized thermal model; a control system settings update unit configured to adapt controller settings based on stress parameters.
