Method for filling a containment vessel with a gaseous medium under pressure, in particular hydrogen

摘要

The present invention relates to a method for filling a containment vessel (for example a vehicle tank) (20) with a gaseous medium under pressure, in particular in the form of hydrogen. Here, a supply tank system (2) storing hydrogen is connected to a storage container (20) to be filled via a filling line (3) and a filling valve (4). In order to cool the filling line (3) to a presettable target temperature under a closed filling valve (4) before filling the containment vessel (20) with the medium, The medium is allowed to flow through the filling line (3), and is discharged from the filling line (3) via a line (5) branched upstream of the filling valve (4). Furthermore, the present invention relates to a filling facility (1) for filling the containment vessel (20).
