Abstract
Es
wird vorgeschlagen, durch eine relativ kleine und kostengünstige Brennstoffzellen-Anordnung
die Starter- bzw. Traktionsbatterie eines Kraftfahrzeugs permanent
zu puffern. Hierdurch wird die Startbereitschaft des Fahrzeugs selbst
nach längerem
Stillstand sichergestellt. Daneben kann der Gebrauchswert des Fahrzeugs
noch dadurch verbessert werden, dass zusätzliche Vorrichtungen oder
Funktionen integriert werden. Bei Fahrzeugen mit zweiter Batterie
- beispielsweise Polizei- oder Camping-Fahrzeuge - kann die Zweitbatterie
entfallen.
Zusammenfassend ergeben sich folgende Merkmale:
· Das Brennstoffzellen-Subsystem
ist einfach in bestehende Konzepte zu integrieren.
· Der Gebrauchswert
der mit dem Gegenstand der Erfindung ausgestatteten Fahrzeuge kann
weiter verbessert werden.
· Die
Lebensdauer der Starter- bzw. Traktionsbatterie wird verlängert.
· Zusatzbatterien
können
entfallen.
· Fahrzeuge
können
für längere Zeit
abgestellt oder stillgelegt werden, ohne dass die Startbereitschaft
verloren geht.It is proposed to permanently buffer the starter or traction battery of a motor vehicle by means of a relatively small and inexpensive fuel cell arrangement. This ensures the readiness of the vehicle to start even after a long standstill. In addition, the usefulness of the vehicle can be further improved by integrating additional devices or functions. For vehicles with a second battery - for example, police or camping vehicles - the second battery can be omitted.
In summary, the following features result:
· The fuel cell subsystem is easy to integrate into existing concepts.
The utility value of vehicles equipped with the subject invention can be further improved.
· The life of the starter or traction battery is extended.
· Additional batteries can be omitted.
· Vehicles can be parked or taken out of service for a longer period of time without losing start-up readiness.
Description
Die vorliegende Erfindung bezieht sich auf die Verwendung von Brennstoffzellen in mobilen Anwendungen.The The present invention relates to the use of fuel cells in mobile applications.
Die Anwendungs-Schwerpunkte der Erfindung betreffen in erster Linie Wasserfahrzeuge und Straßen-Kraftfahrzeuge, daneben auch Flurförderzeuge und Luftfahrzeuge. Ein wichtiges Einsatzgebiet sind Fahrzeuge, bei denen im Stillstand bzw. bei abgeschaltetem Antriebsaggregat über längere Zeit relativ viel Elektrische Energie benötigt wird, ohne dass ein stationärer Netzanschluss genutzt werden kann. Hierzu gehören beispielsweise Polizeifahrzeuge, Rettungsfahrzeuge oder Campingfahrzeuge. In diesen Fahrzeugen verwendet man heute in der Regel zwei Akkumulatorbatterien – bei Anwendung des Erfindungsgedankens kann zumeist die zweite Akkumulatorbatterie entfallen – das spart Kosten und Gewicht.The Application foci of the invention relate primarily Watercraft and road vehicles, besides also industrial trucks and aircraft. An important field of application are vehicles, at those at standstill or with the drive unit off for a long time relatively much electrical energy needed will, without being a stationary Power supply can be used. These include, for example, police vehicles, Rescue vehicles or camping vehicles. Used in these vehicles Today you usually two accumulator batteries - when applied of the inventive concept can usually the second accumulator battery omitted - that saves costs and weight.
Die erfindungsgemäße Anordnung verhindert die schleichende Entladung von Starter- bzw. Traktionsbatterien durch permanent zugeschaltete Verbraucher sowie die Effekte der Selbstentladung. Weil auf diese Weise eine Tiefentladung der Starter- bzw. Traktionsbatterie sicher verhindert wird, kann mit einer deutlich verlängerten Lebensdauer dieser Batterie gerechnet werden. Überschüssige Elektrizität sowie der Wärmeanfall werden in Ausgestaltungen der Erfindung sinnvoll genutzt.The inventive arrangement prevents the creeping discharge of starter or traction batteries by permanently switched consumers and the effects of Self-discharge. Because in this way a deep discharge of the starter or Traction battery can be safely prevented, with a clear extended Life of this battery can be expected. Excess electricity as well the heat attack are used meaningfully in embodiments of the invention.
Brennstoffzellen
als Stromlieferant für
elektrische Fahrzeugantriebe sind schon seit Jahren in der Diskussion.
Beim momentanen Stand der Dinge (2005) rechnen Fachleute nicht damit,
dass Otto- bzw. Dieselmotoren in den nächsten zehn bis fünfzehn Jahren
durch Konzepte basierend auf Brennstoffzellen abgelöst werden.
Es ist zu vermuten, dass für
eine Übergangszeit
von einigen Jahrzehnten Hybridkonzepte den Markt bestimmen werden,
bei denen Wärmekraftmaschinen
mit Traktions-Akkumulatoren und Elektroantrieben kombiniert werden. – Dagegen
können
kleine Brennstoffzellen-Anordnungen auch heute schon sinnvoll in
Kraftfahrzeugen eingesetzt werden. Dies soll anhand eines Beispiels
für die Anwendung
der Erfindung erläutert
werden:
In modernen PKWs, Polizei- oder Rettungsfahrzeugen
oder Segeljachten laufen in steigendem Maße permanent elektrische oder
elektronische Einrichtungen, wie beispielsweise die Einbruchssicherung,
ein elektrisch betriebener Kühlschrank,
Beleuchtungs- oder Funkanlagen oder das Schließsystem. Je nach Akkutyp kommt
noch eine mehr oder weniger starke unvermeidbare Selbstentladung
hinzu. So kommt es häufig
vor, dass nach einer zweiwöchigen
Urlaubsreise mitunter das in der Garage abgestellte Fahrzeug nicht
gestartet werden kann, weil die Starterbatterie mittlerweile entladen
ist. – Insbesondere
bei hochwertigen Fahrzeugen mit vielen Extras ist dies nicht hinnehmbar.Fuel cells as an electricity supplier for electric vehicle drives have been under discussion for years. In the current state of affairs (2005), experts do not expect gasoline and diesel engines to be superseded by fuel cell concepts over the next ten to fifteen years. It is likely that for a transitional period of a few decades, hybrid concepts will dominate the market, where heat engines are combined with traction batteries and electric drives. - In contrast, small fuel cell assemblies can now be used effectively in motor vehicles. This will be explained with reference to an example of the application of the invention:
In modern cars, police or emergency vehicles or sailing yachts are increasingly running permanent electrical or electronic devices, such as burglary protection, an electrically operated refrigerator, lighting or radio equipment or the locking system. Depending on the battery type, a more or less strong unavoidable self-discharge is added. So it often happens that after a two-week vacation trip sometimes parked in the garage vehicle can not be started because the starter battery is now discharged. - Especially with high-quality vehicles with many extras, this is unacceptable.
Vorteile der ErfindungAdvantages of invention
Fahrzeuge, die erfindungsgemäß mit einer kleinen Brennstoffzellen-Anordnung einschließlich Steuereinheit ausgerüstet sind, bleiben auch nach längerer Standzeit voll einsatzbereit, weil eine Entladung der Starter- bzw. Traktionsbatterie sicher verhindert wird. Daneben kann der Gebrauchswert des Fahrzeugs durch die Integration weiterer Funktionen und Geräte deutlich verbessert werden, weil die Restriktion eines höchstzulässigen Stromverbrauches durch die Erfindung deutlich abgemildert wird.Vehicles, the invention with a small Fuel cell arrangement including control unit are equipped, stay even longer Service life fully operational, because a discharge of the starter or Traction battery is safely prevented. In addition, the use value of the vehicle by integrating additional functions and devices be improved because the restriction of a maximum power consumption by the invention is significantly mitigated.
Insgesamt ergeben sich folgende Vorteile:Overall arise the following advantages:
- • Die Startbereitschaft des Fahrzeuges nach längerem Stillstand wird sichergestellt.• The Starting readiness of the vehicle after a long standstill is ensured.
- • Der Gebrauchswert des Fahrzeuges kann durch Integration elektrisch betriebener Zusätze verbessert werden, beispielsweise Leuchten, Kühlboxen, Lüfter.• Of the Use value of the vehicle can be electrically powered by integration additions be improved, such as lights, coolers, fans.
- • Die Lebensdauer der Akkumulator-Batterie wird erheblich verlängert• The Life of the battery is extended considerably
