Method and filling device for filling a storage container with a gaseous medium under pressure for regular usage, hydrogen

The invention relates to a method for filling a storage container (2) with a gaseous pressurized medium, preferably with gaseous, pressurized hydrogen, wherein a gas buffer (10) via an associated valve (20) and an adjoining tank feed line (100), which has a mass flowmeter (30) downstream of the valve (20) and a refueling valve (50) downstream of the mass flow meter (30) with the storage container (2), said first (in a first filling phase with the valve closed 20 ) and open filling valve (50) only (in the tank inlet 100) befindliches, pressurized medium into the storage container (2) is pressed, and wherein the valve (20) for further filling of the storage container (2) is opened when in the first filling phase, the mass flow of the medium through or in the fuel supply line (100) is in a range defined by the Massedurchflussmes Ser (30) can be detected. The invention further relates to a corresponding filling device (1).
