Abstract

The vehicle has a fuel cryogenic tank for storing liquid gas such as liquid hydrogen, under lowest temperatures and low pressure. A supply pressure tank is filled with fluid gas that is completely evaporated in the pressure tank. A drive unit of the vehicle is provided with fuel from the pressure tank when the cryogenic tank is emptied. The amount of the fluid gas supplied to the pressure tank is limited under the consideration of a filling level that is determined at the beginning of a filling process such that the pressure tank is maximally filled when the fluid gas is evaporated.

Description

Die Erfindung betrifft ein Kraftfahrzeug mit einem Kraftstoff-Kryotank zur Speicherung von Flüssiggas, insbesondere von flüssigem Wasserstoff, unter Tiefsttemperaturen und höchstens geringem Überdruck, nach dem Oberbegriff des Anspruchs 1.The The invention relates to a motor vehicle with a fuel cryotank for storing LPG, especially of liquid Hydrogen, below minimum temperatures and at most low overpressure, according to the preamble of claim 1.

Kraftstoffspeichersysteme für kryogenen Wasserstoff befinden sich derzeit im Hinblick auf alternative Kraftfahrzeug-Kraftstoffe der Zukunft in der Vorentwicklungsphase. Dabei besteht bekanntlich die sog. boil-off-Problematik, d.h. dass insbesondere in einem nahezu vollständig gefülltem Kryotank eines über einem längeren Zeitraum nicht bewegten Fahrzeugs durch unvermeidbaren Wärmeeintrag in den Tank darin gespeicherter Flüssigwasserstoff verdampft, was eine Druckerhöhung im Tank bewirkt, die durch Abblasen einer Teilmenge von dann gasförmigem Wasserstoff in die Umgebung abgebaut werden muss. Bei extrem langen Standzeiten des Kraftfahrzeugs (bspw. in der Größenordnung von einem Monat oder länger) könnte dies dazu führen, dass schließlich praktisch sämtlicher Kraftstoff aus dem Kryotank in die Umgebung abgeblasen wurde, wonach das Fahrzeug im Extremfall nicht mehr mit Hilfe von dessen Antriebsaggregat bewegt werden könnte.Fuel Storage Systems for cryogenic hydrogen are currently with regard to alternative motor vehicle fuels the future in the pre-development phase. It is well known that so-called boil-off problem, i. that in particular in a near Completely filled Cryotank one over a longer one Period of non-moving vehicle due to unavoidable heat input vaporized liquid stored in the tank therein, what an increase in pressure in the tank, which by blowing off a subset of then gaseous hydrogen must be mined in the environment. For extremely long service life of the motor vehicle (for example, in the order of one month or longer) could cause this that finally practically all Fuel was blown out of the cryotank into the environment, after which the vehicle in extreme cases, no longer with the help of its drive unit could be moved.

Als Abhilfemaßnahme für diese Problematik ist in der DE 101 05 819 A1 , die zur Bildung des Oberbegriffs des Anspruchs 1 herangezogen ist und von der die vorliegende Erfindung ausgeht, vorgeschlagen. Demnach ist zusätzlich zum Kryotank ein gegenüber dem Fassungsvolumen des Kryotanks erheblich kleinerer Vorrats-Druckbehälter vorgesehen, der mit Flüssiggas aus dem Kryotank befüllt wird, welches im Druckbehälter im wesentlichen vollständig verdampfen kann, dabei jedoch in diesem verbleibt, und aus dem das Antriebsaggregat des Fahrzeugs jedenfalls dann mit Kraftstoff versorgt wird, wenn der Kryotank geleert ist.As a remedy for this problem is in the DE 101 05 819 A1 , which is used to form the preamble of claim 1 and from which the present invention proceeds proposed. Accordingly, in addition to the Kryotank a compared to the capacity of the Kryotanks significantly smaller reservoir pressure vessel is provided which is filled with LPG from the cryotank, which can evaporate substantially completely in the pressure vessel, while remaining in this, and from which the drive unit of the vehicle anyway then supplied with fuel when the cryotank is emptied.

Bei diesem bekannten Stand der Technik ist der Druckbehälter innerhalb des Kryotanks angeordnet, weshalb die Befüllung und Entleerung des Druckbehälters ohne die Notwendigkeit aufwändiger zusätzlicher Armaturen praktisch über oder durch den Kryotank erfolgen kann. Nachteilig ist diese Anordnung jedoch insofern, als durch diesen Druckbehälter wertvoller Speicherraum im Kryotank, der im Hinblick auf seine Integration in einem Kraftfahrzeug bzw. PKW bereits erheblichen Bauraumrestriktionen unterworfen ist, praktisch verloren geht.at In this known prior art, the pressure vessel is inside arranged the cryogenic tank, which is why the filling and emptying of the pressure vessel without the need for elaborate additional Faucets practically over or through the cryotank. The disadvantage is this arrangement however, insofar as valuable storage space through this pressure vessel in the cryogenic tank, which, in view of its integration in a motor vehicle or Car is already subject to considerable space restrictions, practical get lost.

Hiermit soll nun aufgezeigt werden, wie ein solcher bekannter Zusatzspeicher bzw. Reservetank für einen Kryotank, der nach einem anderen Speicherprinzip als der Kryotank arbeitet, nämlich als Druckbehälter aufgebaut bzw. ausgebildet ist, der jedoch weiterhin – ebenso wie der Kryotank – mit Flüssiggas (und somit tiefkalt) befüllt werden kann, bestmöglich befüllt werden kann, wenn dieser Reservebehälter bzw. Druckbehälter außerhalb des Kryotanks angeordnet ist (= Aufgabe der vorliegenden Erfindung).Herewith will now be shown how such a known additional memory or reserve tank for a cryogenic tank, which uses a different storage principle than the cryotank works, namely as a pressure vessel is constructed or formed, but continue - as well like the cryotank - with LPG (and thus deeply cold) filled can be, as best as possible filled can be when this reserve tank or pressure vessel outside of the cryogenic tank is arranged (= object of the present invention).

Zur Lösung dieser Aufgabe wird vorgeschlagen, dass die dem (außerhalb des Kryotanks angeordneten) Druckbehälter beim Befüllen zuführbare Flüssiggas-Menge unter Berücksichtigung von dessen zu Beginn eines Befüllvorganges vorliegenden und geeignet ermittelbaren Befüllgrades derart begrenzt wird, dass dieser Druckbehälter im wesentlichen maximal gefüllt ist, wenn sämtliches darin befindliches Flüssiggas verdampft ist.to solution this task is proposed that the (outside the cryotank arranged) pressure vessel during filling supplyable amount of liquefied gas, taking into account of which at the beginning of a filling process the present and suitably ascertainable degree of filling is limited in such a way that this pressure vessel essentially filled to the maximum is, if all Liquefied gas contained therein has evaporated.

Zunächst kann somit die gleiche Infrastruktur zum Befüllen sowohl des Kryotanks als auch des Reserve- oder Zusatz-Druckbehälters verwendet werden, indem letzterer bei einem Betankungsvorgang ebenso wie der Kryotank mit Flüssiggas befüllt wird. Mit Eintreten des Flüssiggases in den Druckbehälter sowie unter (geringem) zeitlichen Versatz hierzu wird das Flüssiggas in diesem jedoch in den dampfförmigen Zustand übergehen, nachdem am Druckbehälter – wie üblich – keine besonders intensive thermische Isolation vorgesehen ist. Die damit einhergehende Druckzunahme ist jedoch unproblematisch, nachdem der Druckbehälter im Hinblick auf eine Aufnahme eines entsprechend hohen Drucks ausgelegt ist. Somit ist es – anders als beim Kryotank – auch nicht erforderlich, über einem längeren Zeitraum betrachtet Kraftstoff aus dem Druckbehälter abzuführen, zumindest wenn dieser nicht mit einer größeren Menge von Flüssiggas befüllt wurde, als dieser im gasförmigen Zustand unter dann deutlich höherem Druck halten kann. Im Hinblick hierauf soll nun die dem Druckbehälter beim Befüllen zuführbare Flüssiggas-Menge unter Berücksichtigung des zu Beginn eines Befüllvorganges vorliegenden Befüllgrades derart begrenzt werden, dass dieser Druckbehälter im wesentlichen maximal gefüllt ist, wenn sämtliches darin befindliches Flüssiggas verdampft ist. An dieser wird dabei weiterhin der Begriff „Flüssiggas" verwendet, wenngleich dessen Aggregatzustand im verdampften Zustand nicht länger ein flüssiger Aggregatzustand ist.At first you can Thus, the same infrastructure for filling both the cryotank and also the reserve or auxiliary pressure vessel can be used by the latter in a refueling operation as well as the cryotank with LPG filled becomes. With entry of the liquefied gas in the pressure vessel as well under (slight) time offset to this is the LPG but in this case in the vaporous one Pass state, after the pressure vessel - as usual - no particularly intensive thermal insulation is provided. The so However, pressure increase is unproblematic after the pressure vessel designed with a view to receiving a correspondingly high pressure is. So it is - different as at the cryogenic tank - too not required, over a longer one Period regarded considered to remove fuel from the pressure vessel, at least if this not with a larger amount of liquefied gas filled was, as this in the gaseous state under then much higher Can hold pressure. In view of this, now the pressure vessel at fill deliverable Liquefied gas amount below consideration at the beginning of a filling process present filling level be limited so that this pressure vessel substantially maximum filled is, if all Liquefied gas contained therein has evaporated. At this, the term "liquefied gas" will continue to be used, though its state of aggregation in the vaporized state no longer a liquid Physical state is.

Die Erfassung der noch vor Beginn eine Befüllvorgangs im Druckbehälter befindlichen Gasmenge kann auf unterschiedliche Weise erfolgen, so bspw. indem bei bekannter Temperatur, bei bekanntem Fülldruck und für einen definierten Volumenstrom (bspw. über eine eingebaute Drossel oder Blende) die Füllmenge durch die Dauer der Öffnung eines Ventils ermittelt wird.The Detecting the before the start of a filling process located in the pressure vessel Gas quantity can be done in different ways, so for example. By at a known temperature, with known filling pressure and for a defined volume flow (eg a built-in throttle or orifice) the amount of filling through the duration of the opening of a Valve is determined.

Wie bereits erwähnt, wird das dem vorgeschlagenen Druckbehälter im Rahmen einer Befüllung desselben zugeführte Flüssiggas relativ kurzfristig in den gasförmigen Zustand übergehen, wobei eine nicht zu vernachlässigende Kälteenergie zur Verfügung steht bzw. frei wird, indem Wärme aus der Umgebung abgezogen wird. Im Sinne einer vorteilhaften Weiterbildung wird nun vorgeschlagen, diese sog. Kälteenergie zu nutzen, und zwar zur Kühlung des Kryotanks bzw. des Innentanks desselben, und zwar vorzugsweise über eine nur für diesen Fall herstellbare Wärmebrücke. Wenn also dem Kryotank, insbesondere dessen Innentank die im Druckbehälter in Verbindung mit einem Verdampfen des eingefüllten Flüssiggases nachgefragte Verdampfungsenergie entzogen werden kann, so kann dies im Rahmen eines Befüllvorganges der Kryotanks und des Druckbehälters zu einem schnelleren Durchkühlen des Innentanks des Kryotanks und damit zur Reduzierung der Warmbetankungszeit führen. Ausgeführt sein kann eine entsprechende schaltbare Wärmebrücke bzw. Wärmekopplung bspw. in Form eines Federelements, welches am Innentank des Kryotanks befestigt ist und nur bei einer Befüllung des Druckbehälters bspw. mittels Magnetkraft an den Druckbehälter angepresst und damit wärmegekoppelt wird, wobei noch darauf hingewiesen sei, dass dies sowie eine Vielzahl weiterer Details durchaus abweichend von obigen Erläuterungen gestaltet sein kann, ohne den Inhalt der Patentansprüche zu verlassen.As already mentioned, the proposed pressure vessel in the context of a Befül tion of the same supplied LPG relatively short term in the gaseous state, with a not negligible cooling energy is available or is released by heat is removed from the environment. In terms of an advantageous development, it is now proposed to use this so-called. Cold energy, namely for cooling the cryotank or the inner tank thereof, and preferably via a producible only for this case thermal bridge. If, therefore, the cryotank, in particular its inner tank, can be deprived of the evaporation energy required in the pressure vessel in conjunction with vaporization of the filled liquid gas, this can be achieved during a filling operation of the cryotank and the pressure vessel to a faster cooling of the inner tank of the cryotank and thus to reduce the Lead warming time. In the form of a spring element, which is fastened to the inner tank of the cryotank and is pressed against the pressure vessel by means of magnetic force only when the pressure vessel is filled, for example, it should be noted that that this and a variety of other details may well be designed differently from the above explanations, without departing from the content of the claims.
