Method for adjusting the temperature and/or the pressure of fuel in a plurality of pressurized containers of a vehicle to a respective temperature setpoint and/or a respective pressure setpoint before a process of filling the pressurized containers (20, 40 60), comprising the following steps: 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 , and depending on the decision of a control unit , supplying the fuel extracted from the first pressurized container - to 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 , wherein the temperature setpoints and/or the pressure setpoints of the pressurized containers are determined in such a way 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 as high as possible. 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 , and depending on the decision of a control unit , supplying the fuel extracted from the first pressurized container - to 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 , wherein the temperature setpoints and/or the pressure setpoints of the pressurized containers are determined in such a way 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 as high as possible. - to 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 , wherein the temperature setpoints and/or the pressure setpoints of the pressurized containers are determined in such a way 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 as high as possible. <EOS>
