Abstract
A method for operating a device for filling a tank for storing fuel as condensed gas for a consumer that can be operated with cryogenically stored fuel. Included is at least one filling line and one extraction line for connecting to a filling device on a gas-station-side. In a first time period for cooling the tank, the condensed gas is introduced into the tank, at least the large part is extracted again in the form of gas via the extraction line, and in a second subsequent time period, the tank is filled with condensed gas at the same time as at least the displaced gas is extracted. In a subsequent third time period, the filling line is closed and the extraction line is maintained open in order to guide the gas from the tank back until the pressure and/or the temperature in the tank is/are lowered to defined values.
