Abstract

The invention relates to a method for preparing to refuel a tank in a vehicle with hydrogen, for which purpose the tank pressure is lowered in preparation for driving to a filling station, wherein the filling station is informed of the pending refueling. The method according to the invention is characterized in that the refueling takes place with liquid hydrogen, wherein the maximum achievable pressure level of the tank during refueling, the expected pressure level of the tank when the filling station is reached, and the expected refueling quantity are transmitted to the filling station.
