Method for Displaying a Fill Level of a Pressure Vessel, and Pressure Vessel Assembly

A method for displaying a fill level of a pressure vessel includes measuring an actual fill level of the pressure vessel, calculating a displayable fill level based on the actual fill level, and displaying the displayable fill level via a display device. In the method, during refueling between a first filling point (FP) and a second filling point (FP), the displayable fill level is increased in relation to the actual fill level in accordance with a predefined characteristic curve.
