A method for performing a pressure test on a tank (e.g. hydrogen tank) and a filling apparatus is disclosed. The tank is connected via a tank valve to a tank feed line which has a first valve for shutting off the tank feed line, wherein during the pressure test prior to the tank being filled through the tank feed line a flow of medium, with the first valve closed, is directed into the tank via a bypass line bridging the first valve, wherein the flow of medium is throttled in the bypass line such that a tank feed pressure acting on the tank valve rises in a controlled manner, wherein the tank valve opens particularly when the tank feed pressure exceeds the pressure prevailing in the tank.

Method for performing a pressure test on a tank and tank filling apparatus

A method for filling up a storage tank (e.g., a vehicle tank) with a gaseous, pressurized medium, in particular in the form of hydrogen, in which a supply tank system for storing the hydrogen is connected with the storage tank to be filled by way of a tank feed line and a fueling valve, wherein, prior to filling up the storage tank with aforesaid medium with the fueling valve closed, a flow of the medium for cooling the tank feed line is guided through the tank feed line at a predefinable target temperature, and removed from the tank feed line through a line that branches away upstream from the fueling valve. The disclosure further provides for a fueling facility for filling up a storage tank.
