Ausgehend von dem vorgenannten Stand der Technik ergibt sich die folgende Situation.outgoing from the aforementioned prior art, the following results Situation.
Die Verwendung von APU zur Unterstützung der Spannungsversorgung in einem Kraftfahrzeugbordnetz ist bekannt. Ebenso bekannt ist die Verwendung von Kondensatoren oder Supercaps als Energieversorgung für den Startvorgang eines Verbrennungsmotors. Bisher nicht bekannt geworden sind Bordnetze, deren Energiemanagement für die elektrische Energieversorgung alleine auf einer APU baut und die auf eine Batterie als Energiespeicher für den Startvorgang des Verbrennungsmotors verzichten.The Use of APU to support the Power supply in a motor vehicle electrical system is known. Also known is the use of capacitors or supercaps as an energy supply for the starting process of an internal combustion engine. Not known yet have become electrical systems, their energy management for the electrical Power alone builds on an APU and builds on a battery as energy storage for abandon the starting process of the internal combustion engine.
Erfindungsgemäße Aufgabe war es daher, ein Bordnetz anzugeben, dessen Energiemanagement sowohl während des Betriebs des Fahrzeugmotors als auch bei Stillstand des Fahrzeugmotors ohne Speicherbatterie auskommt.Task according to the invention It was therefore to specify an electrical system whose energy management both while the operation of the vehicle engine as well as at standstill of the vehicle engine without Storage battery manages.
Die Aufgabe wird gelöst mit einem Bordnetz nach Anspruch 1. Weitere Ausführungsformen und Ausführungsbeispiele sind in den Unteransprüchen und in der folgenden Beschreibung offenbart.The Task is solved with a vehicle electrical system according to claim 1. Further embodiments and embodiments are in the dependent claims and disclosed in the following description.
Die Aufgabe wird hauptsächlich mit einem Bordnetz gelöst, dessen Bordnetzgenerator durch einen von dem Fahrzeugmotor unabhängigen Hilfsverbrennungsmotor angetrieben wird. Bordnetzgenerator und Hilfsverbrennungsmotor bilden eine so genannte APU. Die für den Startvorgang des Fahrzeugmotors benötigte Energie wird in Kondensatoren, vorzugsweise in Supercorps, gespeichert. Ein Energiemanagement sorgt dafür, dass eine Ladungsüberwachung der Supercorps erfolgt und im Falle des Unterschreitens einer für einen zukünftigen Startvorgang notwendigen Mindestladung, ein Nachladen durch die APU erfolgt.The Task becomes mainly solved with a vehicle electrical system, the electrical system generator by an independent of the vehicle engine auxiliary combustion engine is driven. Electrical system generator and auxiliary combustion engine form a so-called APU. The for the starting process of the vehicle engine required energy is in capacitors, preferably in Supercorps, saved. An energy management ensures that a charge monitoring the supercorps takes place and in case of falling below one for one future Boot process necessary minimum charge, a reload by the APU takes place.
Ist die APU beim Unterschreiten der Mindestladung in den Supercorps außer Betrieb, wird vom Energiemanagement ein Start des Hilfsverbrennungsmotors der APU veranlasst und die Supercorps werden wieder aufgeladen.is the APU falls below the minimum charge in the Supercorps except Operation, the energy management is a start of the auxiliary combustion engine The APU arranges and the Supercorps are recharged.
Als Rückfallebene, falls das Energiemanagement einmal versagen sollte, verfügt der Hilfsverbrennungsmotor der APU über einen manuellen Reversierstarter. Nach manuellem Start des Hilfsverbrennungsmotors können dann die Supercaps vorrangig aufgeladen werden. Nach einer Ladedauer von etwa 10 Sekunden sind dann die Supercaps soweit aufgeladen, dass der Fahrzeugmotor gestartet werden kann.When Fallback if the energy management should fail once, has the auxiliary combustion engine the APU over a manual recoil starter. After manual start of the auxiliary combustion engine can then the supercaps are charged with priority. After a charging time of about 10 seconds are then the supercaps charged so far that the vehicle engine can be started.
Mit
der Erfindung werden hauptsächlich
folgende Vorteile erzielt:
Viele LKW Fahrer lassen bisher den
Fahrzeugmotor bei einer Übernachtung
durchlaufen (Idling over night), um elektrische Komfortverbraucher
während dieser
Zeit problemlos betreiben zu können.
Ohne Idling over night würden
sie sonst Gefahr laufen am nächsten
Morgen die Antriebsmaschine nicht mehr starten zu können, weil
die Starterbatterie leer ist. Mit einem erfindungsgemäßen Bordnetz
kann hierfür
die APU eingesetzt werden. Das spart Treibstoff und Abgasemissionen.With the invention mainly the following advantages are achieved:
Many truck drivers have previously run the vehicle engine during an overnight stay (idling over night) to electric comfort consumers during to be able to operate this time without any problems. Without idling over night, they would otherwise run the risk of being unable to start the prime mover the next morning because the starter battery is dead. With an electrical system according to the invention, the APU can be used for this purpose. This saves fuel and exhaust emissions.
Eine APU kann mittels ihres 1-Zylinder Verbrennungsmotors als Hilfsverbrennungsmaschine und dem damit angetriebenen Generator über Nacht genügend elektrische Energie für das Bordnetz eines LKW erzeugen.A APU can by means of its 1-cylinder internal combustion engine as auxiliary combustion engine and the alternator is powered by enough electrical power overnight Energy for generate the electrical system of a truck.
Der Einsatz von Supercaps an Stelle einer Starterbatterie erhöht auch die Zyklenfestigkeit des Energiespeichers für den Startvorgang der Antriebsmaschine. Herkömmliche Bleiakkumulatoren haben hier in Bezug auf Zyklenfestigkeit deutliche Nachteile.Of the Use of supercaps in place of a starter battery also increases the cycle stability of the energy storage for the starting process of the prime mover. conventional Lead-acid batteries have clear advantages in terms of cycle stability Disadvantage.
Ein Energiemanagement übernimmt je nach Ladezustand der Supercaps den Selbststart oder den Nachlauf der APU zum Nachladen der Superkondensatoren.One Energy management takes over depending on the state of charge of the supercaps the self-start or the caster the APU to recharge the supercapacitors.
Bei dem erfindungsgemäßen Bordnetz können somit Starterbatterien mit großer Kapazität und von der Antriebsmaschine angetriebene Bordnetzgeneratoren entfallen.at the electrical system according to the invention can thus starter batteries with great capacity and driven by the engine power supply generators omitted.
Die APU ermöglicht eine energetisch optimierte Erzeugung der elektrischen Energie für das Bordnetz, da die APU stets bei wirkungsoptimaler Drehzahl betrieben werden kann.The APU enabled an energetically optimized generation of electrical energy for the electrical system, because the APU are always operated at optimal speed can.
