Abstract

The invention relates to a method for filling a storage container (a vehicle tank, for example) (20) with a pressurized gaseous medium, in particular in the form of hydrogen. A supply storage system (2) for storing the hydrogen is connected to the storage container (20) to be filled via a tank supply line (3) and a filling valve (4). Prior to filling the storage container (20) with the medium, a flow of the medium is conducted through the tank supply line (3) while the filling valve (4) is closed in order to cool the tank supply line (3) to a definable target temperature, and the flow is discharged from the tank supply line (3) via a line (5) which branches off upstream of the filling valve (4). The invention further relates to a filling device (1) for filling a storage container (20).

Since the hydrogen is to be present for the refueling in the gaseous phase, has such
Betankungseinrichtung für gewöhnlich über einen Gaspufferspeicher, der sich aus dem vorgenannten (Flüssigwasserstoff-) Speicher speist und den gasförmigen Wasserstoff vorhält. Um die Sicherheit (Explosionsgefahr) für die Umwelt beim Betanken von  Refueling device usually via a gas storage tank, which feeds from the aforementioned (liquid hydrogen) storage and holds the gaseous hydrogen. To increase the safety (risk of explosion) for the environment when refueling
Wasserstofftanks (z.B. Fahrzeugtank) mit Wasserstoff zu gewährleisten und um einen Standard für den Betankungsprozess zu schaffen, wurde der Standard SAE J2601 geschaffen. Der Standard gibt u.a. sicherheitsrelevante Grenzen und  To ensure hydrogen tanks (e.g., vehicle tank) with hydrogen and to establish a standard for the refueling process, the SAE J2601 standard was created. The standard gives u.a. safety-relevant limits and
Leistungsanforderungen für den Tankvorgang vor. SAE J2601 sieht vor, dass wasserstoffgetriebene Fahrzeuge innerhalb von drei Minuten betankt werden sollen, ohne dass dabei die Temperatur des Wasserstoffs über eine Temperatur von 85 °C ansteigt. Gleichzeitig wird verlangt, dass die Temperatur des Wasserstoffs während des Betankens bei Eintritt in den Speicherbehälter -40 °C nicht unterschreitet. Ebenso existieren Regularien für die zugelassenen Temperaturschwankungen während des Betankens. Performance requirements for refueling. SAE J2601 envisages that hydrogen-powered vehicles should be refueled within three minutes without the temperature of the hydrogen rising above 85 ° C. At the same time it is required that the temperature of the hydrogen during refueling when entering the storage tank does not fall below -40 ° C. There are also regulations for the permitted temperature fluctuations during refueling.
Um weder die maximal zulässige Temperatur von 85 °C während des Betankens zu überschreiten noch die limitierte Vorkühlung des Wasserstoffs von -40 °C zu unterschreiten, muss der Wasserstoff zum Betanken eines Speicherbehälters daher u.a. innerhalb von vorzugsweise 25 s auf einen vergleichsweise schmalen In order not to exceed the maximum allowable temperature of 85 ° C during refueling nor the limited pre-cooling of the hydrogen from -40 ° C to The hydrogen for refueling of a storage container therefore has to fall, inter alia, within preferably 25 seconds to a comparatively narrow one
Temperaturbereich von -33 bis -40 °C temperiert werden. Aufgrund der wechselnden Temperaturverhältnisse in den Rohrleitungen ist eine konstante Temperatur des Wasserstoffs (von z.B. -40 °C) an der Zapfsäule Temperature range of -33 to -40 ° C tempered. Due to the changing temperature conditions in the piping, there is a constant temperature of the hydrogen (of e.g. -40 ° C) at the pump
vergleichsweise aufwändig und kostenintensiv zu realisieren. Dies liegt unter anderem daran, dass es nach Beendigung eines Tankvorgangs zu einer Angleichung der Tankzuleitungstemperatur an die Umgebungstemperatur kommt. Eine zu sehr erwärmte Tankzuleitung kann also dazu führen, dass der Wasserstoff an der Zapfsäule nicht innerhalb einer vorgegebenen Zeitspanne den vorgegebenen Temperaturbereich von -33 bis -40 °C erreicht und der Tankvorgang daher abgebrochen werden muss. to realize comparatively complex and costly. Among other things, this is due to the fact that after completion of a refueling process, the tank supply temperature is brought to the ambient temperature. Too much heated tank supply can therefore cause the hydrogen at the pump not within a predetermined period of time reaches the predetermined temperature range of -33 to -40 ° C and the refueling process must therefore be terminated.
Um dies zu verhindern, benötigt man bei langen Tankzuleitungen eine Kühlung der Tankzuleitung oder eine Kühlvorrichtung, die möglichst nahe an der Füllkupplung zum Speicherbehälter positioniert ist. Eine Kühlung der Tankzuleitung ist jedoch mit hohen Kosten verbunden und eine Kühlvorrichtung an der Füllkupplung muss mit der gesamten benötigten Kälteleistung versorgt werden, was wiederum die Kühlvorrichtung und die verbindenden Leitungen erheblich verteuert. In order to prevent this, cooling of the tank feed line or a cooling device which is positioned as close as possible to the filling coupling to the storage tank is required for long tank feed lines. However, a cooling of the tank supply line is associated with high costs and a cooling device on the filling coupling must be supplied with the entire required cooling capacity, which in turn significantly increases the cost of the cooling device and the connecting lines.
Hiervon ausgehend liegt daher der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, bei dem die Tankleitung zügig und vergleichsweise kostengünstig so gekühlt werden kann, dass der Wasserstoff beim Einleiten in den Speicherbehälter bzw. Fahrzeugtank die gewünschte Temperatur aufweist. On this basis, therefore, the present invention seeks to provide a method of the type mentioned, in which the tank line can be cooled quickly and comparatively inexpensive so that the hydrogen has the desired temperature when introduced into the storage tank or vehicle tank.
