Abstract
A method for controlling a temperature of a battery cell () in a battery module (), the method comprising the steps of: determining an initial temperature of the battery cell (); measuring a current (I) flowing into or out of the battery cell (); determining an actual temperature gradient of the battery cell () using a thermal battery cell model described by a differential equation, for which input values comprise at least the determined initial temperature and the measured current (I); comparing the determined actual temperature gradient of the battery cell () with a pre-defined desired temperature gradient; and automatically adjusting the current (I) flowing into or out of the battery cell () according to a result of the comparison.
