    Abstract: A method for determining a state of health (SOH) of a rechargeable battery (14) comprises: determining a change in charge (Q x ) within an upper border and a lower border of a charging state window, the change in charge (Q x ) being determined by summing up current values measured within the charging state window; determining an actual state of health (SOH x ) by scaling the change in charge (Q x ) with the width of the charging state window and dividing by an initial charging capacity (Q 1 ) of the battery; and determining an averaged state of health (SOH i ) by calculating a sliding average of the actual state of health (SOH x ) with at least one previous determined state of health.
