Method for Setting the Temperature and/or the Pressure of Fuel, in Particular of Hydrogen, in Multiple Pressure Vessels of a Vehicle to in Each Case One Temperature Setpoint Value and/or in Each Case One Pressure Setpoint Value Before a Filling Process of the Pressure Vessels

A method for adjusting the temperature and/or the pressure of fuel in a pressured container system of a vehicle having a plurality of pressurized containers to a respective temperature setpoint and/or a respective pressure setpoint before a process of filling the pressurized containers, the method comprising the acts of:

• extracting fuel from a first pressurized container, wherein the fuel in the first pressurized container has a first temperature and a first pressure, to bring the first temperature and/or the first pressure of the fuel closer to the temperature setpoint and/or to the pressure setpoint of the first pressurized container;
• supplying, based on a determination from a control unit of the pressured container system, the fuel extracted from the first pressurized container to either:
• a fuel conversion device to power the vehicle, or
• into a second pressurized container, wherein the fuel in the second pressurized container has a second temperature and a second pressure, to bring the second temperature and/or the second pressure of the fuel closer to the temperature setpoint and/or to the pressure setpoint of the second pressurized container;
• and
• determining the temperature setpoints and/or the pressure setpoints of the pressurized containers such that, without exceeding the respective maximum operating pressure and the respective maximum operating temperature of the respective pressurized container, the amount of fuel introduced from a single filling source by a process of filling the pressurized containers which is carried out at the same time and for the same length of time is maximized.
