Zusammenfassung:A backup energy source (1) for an automotive system (102) in a motor vehicle (101) is designed to receive a main supply voltage (Vbatt), during a normal operating condition, and to provide a backup supply voltage (Vsc) during a failure operating condition, different from the normal operating condition. The backup energy source (1) has a control unit (2), and a supercapacitor group (4), operable by the control unit (2) to store energy during the normal operating condition and to provide the backup supply voltage (Vsc) during the failure operating condition. A diagnostic module (10) is coupled to the supercapacitor group (4) to provide the control unit (2) with information concerning an operating status of the supercapacitor group (4).
