Beschreibung
Zusammenfassung:	The detection method has a voltmeter (7) for continuous monitoring of the automobile battery voltage or the voltage of the generator (2) providing the charging voltage for the battery (1), with the battery voltage increased to a defined value indicated by a control device (5) and discharged to a second voltage level via connection to the onboard network load (6), the control device evaluating the voltage gradients for providing a signal indicating the battery condition.
