Description

Die Erfindung betrifft ein Verfahren zum Befüllen eines Speicherbehälters mit einem gasförmigen, unter Druck stehenden Medium, vorzugsweise mit gasförmigem, unter Druck stehenden Wasserstoff.The The invention relates to a method for filling a storage container with a gaseous, pressurized medium, preferably gaseous, pressurized hydrogen.

Gattungsgemäße Verfahren zum Befüllen eines Speicherbehälters kommen beispielsweise bei der Befüllung von Fahrzeug-Speicherbehältern bzw. -tanks mit unter Druck stehendem Wasserstoff zur Anwendung. Mittels derartiger Befüllprozesse können Fahrzeugtanks bis zu Drücken von 700 bar bei 15°C befüllt werden.Generic method for filling a storage container come for example in the filling of vehicle storage tanks or tanks with pressurized hydrogen for use. By means of such filling processes can Vehicle tanks up to pressures from 700 bar at 15 ° C filled become.

Hierbei wird gefordert, dass der Befüllvorgang für unterschiedlichste Fahrzeugtankgrößen ohne ein Überfüllen und/oder Überhitzen des Fahrzeugtanks realisiert werden kann. Derzeit kommuniziert die Wasserstoff-Tankstelle mit dem zu betankenden Fahrzeug entweder über ein Kommunikationskabel, das im Regelfall in der Befüllkupplung integriert ist, oder über eine Infrarotschnittstelle.in this connection is required that the filling process for different ones Vehicle tank sizes without overfilling and / or overheating the vehicle tank can be realized. Currently it communicates Hydrogen station with the vehicle to be refueled either via Communication cable, which is usually integrated in the filling coupling, or over an infrared interface.

Aufgrund der von dem zu betankenden Fahrzeugtank erhaltenen Informationen, wie Druck, Temperatur, etc., wird ein spezielles durchflussgesteuertes Regelventil mittels einer SPS-Auswertung angesteuert, um unterschiedliche Fahrzeugtankgrößen unabhängig betanken zu können. Das vorgenannte durchflussgesteuerte Regelventil hat die Aufgabe, den Durchfluss innerhalb eines vorbestimmten Bereiches zu halten und das Überschreiten einer Durchfluss-Obergrenze zu verhindern. Die Steuerung dient bzw. bestimmt nicht nur die Korrektur des aktuellen Massendurchflusses, sondern veranlasst darüber hinaus einen Betankungsabbruch, wenn der Durchfluss zu gering oder zu groß ist.by virtue of the information obtained from the vehicle tank to be refueled, such as pressure, temperature, etc., becomes a special flow-controlled Control valve controlled by a PLC evaluation to different Fuel vehicle tank sizes independently to be able to. The aforementioned flow-controlled control valve has the task, the To keep flow within a predetermined range and the crossing to prevent a flow limit. The controller is or not only determines the correction of the current mass flow, but induce about it In addition, a refueling stop if the flow is too low or is too big.

Bei derzeit realisierten Tankstellen für gasförmigen, unter Druck stehenden Wasserstoff wird mittels einer fest eingestellten Drossel der Wasserstoff-Durchfluss auf maximal 100 g/s begrenzt. Bei vergleichsweise kleinen Fahrzeugtankgrößen – gemeint sind hierbei Speichervolumina mit einem Fassungsvermögen von weniger als 75 Liter – kann es jedoch aufgrund des negativen Joule-Thompson-Effekts und aufgrund der adiabatische Kompression des Wasserstoffes zu einer Überhitzung des zu befüllenden Fahrzeugstanks kommen. Die Befüllung derartiger Fahrzeugtanks ist daher mit herkömmlichen Betankungsanlagen für gasförmigen, unter Druck stehenden Wasserstoff nicht möglich.at currently realized gas stations for gaseous, pressurized Hydrogen is the hydrogen flow rate by means of a fixed throttle limited to a maximum of 100 g / s. For comparatively small vehicle tank sizes - meant here are storage volumes with a capacity of less than 75 liters - can However, due to the negative Joule-Thompson effect and due to the adiabatic compression of hydrogen to overheating of the vehicle tank to be filled come. The filling Such vehicle tanks is therefore conventional refueling systems for gaseous, pressurized hydrogen is not possible.

Da jedoch die Unabhängigkeit des Fahrzeugtankdesigns und damit auch der Fahrzeugtankgröße von der Automobilindustrie gefordert wird, stellt sich dem Fachmann die Aufgabe, ein gattungsgemäßes Verfahren zum Befüllen eines Speicherbehälters mit einem gasförmigen, unter Druck stehenden Medium, vorzugsweise mit Wasserstoff anzugeben, das die vorgenannten Nachteile vermeidet und ein Befüllen unterschiedlichster Fahrzeugtankgrößen ermöglicht, ohne dass es zu einem Überfüllen und/oder Überhitzen des Fahrzeugtanks kommt.There but independence the vehicle tank design and thus also the vehicle tank size of the Automotive industry is required, the expert faces the Task, a generic method for filling a storage container with a gaseous, pressurized medium, preferably with hydrogen, which avoids the aforementioned disadvantages and filling a wide variety Vehicle tank sizes allows without causing overfilling and / or overheating the vehicle tank comes.

Zur Lösung dieser Aufgabe wird ein gattungsgemäßes Verfahren zum Befüllen eines Speicherbehälters mit einem gasförmigen, unter Druck stehenden Medium, vorzugsweise mit Wasserstoff vorgeschlagen, das dadurch gekennzeichnet ist, dass zu Beginn des Befüllvorganges mittels eines Druckteststoßes eine Bestimmung des Speicherbehälterinnendrucks und anschließend in Abhängigkeit von dem ermittelten Speicherbehälterinnendruck ein Befüllvorgang mit zeitgesteuertem Druckanstieg bis zu dem gewünschten Speicherbehälterinnendruck erfolgt.to solution This object is a generic method for filling a storage container with a gaseous, pressurized medium, preferably with hydrogen, which is characterized in that at the beginning of the filling process by means of a pressure test shock a determination of the storage tank internal pressure and subsequently in dependence of the determined storage tank internal pressure a filling process with timed pressure rise up to the desired storage tank internal pressure.

Erfindungsgemäß erfolgt nunmehr zu bzw. vor Beginn des eigentlichen Befüllvorganges eine Bestimmung des Speicherbehälterinnendrucks. Dazu wird nach dem Fixieren der Betankungskupplung an dem zu betankenden Fahrzeug ein sog. Druckteststoß realisiert, der zum einen die Dichtheit der hergestellten mechanischen Verbindung zwischen Kupplung und Fahrzeug überprüft und zum anderen eine eindeutige Bestimmung des Speicherbehälterinnendrucks ermöglicht.According to the invention now at or before the beginning of the actual filling a determination the storage tank internal pressure. To is after fixing the refueling coupling to the refueling Vehicle realized a so-called pressure test shock, on the one hand the tightness of the produced mechanical connection checked between the clutch and the vehicle and to others a clear determination of the storage tank internal pressure allows.

In Abhängigkeit von dem so ermittelten Speicherbehälterinnendruck wird dann ein Befüllvorgang mit zeitgesteuertem Druckanstieg bis zu dem gewünschten Speicherbehälterinnendruck realisiert. Dazu wird nach der Ermittelung des Startdrucks der Enddruck in Abhängigkeit von den Parametern Speicherbehältertemperatur, Gastemperatur, Kompressibilität und Joule-Thompson-Effekt errechnet. Der Betankung- bzw. Befüllvorgang ist dann beendet, wenn dieser errechnete Enddruck oder der für die maximale Betriebstemperatur zulässige maximale Betriebsdruck des zu betankenden Speicherbehälters erreicht ist.In dependence from the thus determined storage tank internal pressure is then a filling with timed pressure rise up to the desired reservoir pressure inside realized. For this purpose, after the determination of the starting pressure, the final pressure dependent on from the parameters storage tank temperature, Gas temperature, compressibility and Joule-Thompson effect calculated. The refueling or filling process is then terminated when this calculated final pressure or for the maximum Operating temperature permissible maximum operating pressure of the tank to be refueled reached is.

Das erfindungsgemäße Verfahren zum Befüllen eines Speicherbehälters mit einem gasförmigen, unter Druck stehenden Medium, vorzugsweise mit Wasserstoff, vermeidet wirkungsvoll ein Überfüllen und/oder Überhitzen des zu befüllenden Speicherbehälters, unabhängig von dessen Speichervolumen.The inventive method for filling a storage container with a gaseous, under pressurized medium, preferably with hydrogen avoids effectively overfilling and / or overheating of the storage container to be filled, regardless of its storage volume.

Das erfindungsgemäße Verfahren zum Befüllen eines Speicherbehälters weist darüber hinaus den Vorteil auf, dass aufgrund der realisierten, kontrollierten Druckerhöhung der zu befüllende Speicherbehälter mehr Masse an zu speicherndem Medium aufnehmen kann, da der Temperaturanstieg aufgrund des erfindungsgemäßen Verfahrens kontrollierbarer und für jede Speicherbehältergröße gleich ist. Des Weiteren kann auf die bisher erforderliche komplizierte Regelungstechnik sowie die vorgenannten Komponenten, wie Infrarotschnittstelle, etc., verzichtet werden.The inventive method for filling a storage container also has the advantage that due to the realized, controlled pressure increase of the storage container to be filled more mass to be stored medium can absorb, since the temperature increase due to the inventive method kon more controllable and equal for each storage bin size. Furthermore, the previously required complicated control technology as well as the aforementioned components, such as infrared interface, etc., can be dispensed with.

Weitere Vorteile des erfindungsgemäßen Verfahrens zum Befüllen eines Speicherbehälters mit einem gasförmigen, unter Druck stehenden Medium sind darin zu sehen, dass der Befüll- bzw. Betankungsvorgang weniger aufwendig ist, da bspw. das bisher erforderliche Anschließen eines das zu betankende Fahrzeug mit der Tankstelle "verbindende" Kommunikationskabel entfällt; dies ist insbesondere dann von Vorteil, wenn die Befüllprozedur durch Nicht-Fachpersonal vollzogen wird. Auch die mit den bisher verwendeten Infrarotschnittstellen verbundenen Nachteile, wie bspw. Abbruch wegen eines Störfalles, können nunmehr vermieden werden.Further Advantages of the method according to the invention for filling a storage container with a gaseous, Under pressure medium can be seen that the filling or Refueling process is less expensive because, for example, the previously required Connect a vehicle to be refueled with the gas station "connecting" communication cable eliminated; this is particularly advantageous if the filling procedure by non-specialist personnel. Also with the hitherto used infrared interfaces associated disadvantages, such as. Demolition because of an accident, can now be avoided.

Es sei betont, dass das erfindungsgemäße Verfahren zum Befüllen eines Speicherbehälters mit einem gasförmigen, unter Druck stehenden Medium nicht auf die Befüllung eines Speicherbehälters mit gasförmigem, unter Druck stehendem Wasserstoff beschränkt ist. Vielmehr kann das erfindungsgemäße Verfahren bei allen Medien, bei denen während des Befüllvorganges ein kontrollierter Druckanstieg gewünscht oder erforderlich ist, Anwendung finden kann.It be emphasized that the inventive method for filling a storage container with a gaseous, pressurized medium does not affect the filling of a storage container with gaseous, is limited to pressurized hydrogen. Rather, that can inventive method in all media during which the filling process a controlled increase in pressure is desired or required, Application can be found.
