Gegenstand der Erfindung ist ein elektrisches Versorgungssystem, bei dem ein vorhandenes elektrisches System wie beim Stand der Technik gehandhabt wird, aber diesem System ein zweites elektrisches System hinzugefügt ist. Das zweite elektrische System verwendet einen Thermogenerator, der die Abwärme aus dem Verbrennungsprozess zumindest zum Teil in elektrische Energie umwandelt. Die elektrische Energie wird vorteilhafterweise in einem elektrischen Speicher gespeichert und kann über einen DC/DC-Wandler auf die erforderlichen Spannungspegel transformiert werden.object The invention is an electrical supply system, in which a existing electrical system as handled in the prior art but a second electrical system is added to this system. The second electrical system uses a thermogenerator, which the waste heat from the combustion process at least partly into electrical energy transforms. The electrical energy is advantageously in an electrical Memory is stored and can be over a DC / DC converter to the required voltage levels transformed become.
Bei der Erfindung kann der Speicher ein Flüssig-/Elektrolyt-Speicher – wie übliche Akkumulatoren – sein; er kann jedoch auch als Trocken-Elektrolyt-Speicher ausgebildet sein. Daneben können Doppelschichtkondensator-basierte Speicher, sog. SUPERCaps, eingesetzt werden.at According to the invention, the memory may be a liquid / electrolyte reservoir, such as conventional accumulators; However, it can also be designed as a dry electrolyte reservoir be. In addition, double-layer capacitor-based Memory, so-called SUPERCaps, are used.
Die Wahl des Speichers hängt erfindungsgemäß davon ab, wie viele zusätzliche Aggregate im Kraftfahrzeug gespeist werden müssen, wie schnell der Lastwechsel zu erfolgen hat und wie groß das Gewicht des Speichers ist.The Choice of memory depends according to the invention thereof from how many extra Units in the motor vehicle must be fed, how fast the load change has to be done and how big the weight of the memory is.
Bei der Erfindung ist wesentlich, dass der Speicher absolut zuverlässig und wartungsfrei ist. Insbesondere kann der Speicher einen Funktransmitter als Sender versorgen, der in der Lage ist, Funksensoren elektrisch zu versorgen und auszulesen. Dafür sind insbesondere RFID-Tags mit Speicherelementen vorgesehen.at The invention is essential that the memory absolutely reliable and is maintenance-free. In particular, the memory may be a radio transmitter as a transmitter that is capable of wireless sensors electrically to supply and read out. Therefore In particular, RFID tags with memory elements are provided.
Unabhängig von letzterer vorteilhafter Anwendung versorgt der Speicher auch verdrahtete Aggregate. Solche Aggregate sind vorzugsweise Aggregate geringer Verlustleistung, wie z. B. Sensoren. Insbesondere, wenn solche Sensoren berührungslos abtragbar sind und im Rahmen der RFID-Technologie Funktransmitter verwendet werden, lässt sich das zusätzliche Versorgungssystem vorteilhaft einsetzen.Independent of The latter also advantageously uses wired memory for the latter advantageous application Aggregates. Such aggregates are preferably less aggregates Power loss, such. B. sensors. In particular, if such sensors contactless ablatable are and used in the context of RFID technology radio transmitter be, lets the extra Advantageously use the supply system.
Weiterhin ist im Rahmen des erfindungsgemäßen Versorgungssystems die Funktion eines Notaggregates vorgesehen, das automatisch in Wirkung tritt, sofern das vorhandene Versorgungssystem versagt. Beispielsweise ist dabei die Warnblinkanlage bzw. die Fahrzeugabsicherung und/oder Notalarmabsicherung zu versorgen.Farther is within the scope of the supply system according to the invention provided the function of an emergency unit, which automatically in Effect occurs if the existing supply system fails. For example, the hazard warning system or the vehicle insurance is and / or emergency alarm protection.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus der nachfolgenden Figurenbeschreibung anhand eines Ausführungsbeispieles in Verbindung mit den Patentansprüchen. Die einzige Figur zeigt einen thermogeneratorgetriebenes elektrisches Zusatzversorgungssystem für ein Kraftfahrzeug.Further Details and advantages of the invention will become apparent from the following Description of the figures based on an embodiment in conjunction with the claims. The sole figure shows a thermogenerator driven electric Additional supply system for a motor vehicle.

Bei der vorstehend im Einzelnen beschriebenen Einrichtung ist vorteilhaft, dass das Zusatzversorgungssystem komplett wartungsfrei ist. Insbesondere ist das Zusatzversorgungssystem unabhängig vom vorhandenen Versorgungssystem und auch dann betriebsbereit, wenn das vorhandene Versorgungssystem versagt.at the device described in detail above is advantageous, that the additional supply system is completely maintenance-free. Especially the supplementary supply system is independent of the existing supply system and also ready for use when the existing supply system failed.
Das beschriebene Versorgungssystem soll i. A. das vorhandene Hauptversorgungssystem nicht ersetzen, da es von der Abfallenergie im Primärenergiekreis lebt. Es kann aber immer dann alle sicherheitsrelevanten Aufgaben übernehmen, wenn das Hauptversorgungssystem versagt.The described supply system should i. A. not the existing main supply system replace, because it lives on the waste energy in the primary energy cycle. However, it can always take over all safety-relevant tasks if the main supply system fails.
Aus letzterem Grund ist das Zusatzversorgungssystem auch bei voll funktionsfähigem Betrieb des Hauptversorgungssystems für die Versorgung von bestimmten Zusatzaggregaten, beispielsweise von solchen Sensoren, die in zunehmender Weise in Kraftfahrzeugen eingesetzt werden. Insbesondere der Betrieb von Funksensoren, wird damit ermöglicht.Out The latter reason is the additional supply system even with fully functional operation of the Main supply system for the supply of certain ancillary equipment, such as such sensors, which are increasingly used in motor vehicles become. In particular, the operation of wireless sensors, is thus possible.
