Abstract

See full text

The invention relates to a method and device for filling a tank with pressurized gas, comprising transfer of a predefined amount of a gas into the tank from at least one pressurized gas source via a filling duct, the gas being selectively cooled by a cooling component before it enters into the tank in order to prevent a defined temperature limit from being reached in the tank, characterized in that the method comprises a step of defining the maximum amount of energy that can be added to the tank without exceeding the temperature limit, this maximum amount of energy being expressed in the form of the maximum enthalpy that can be added to the tank, a step of defining the effective amount of energy that will be added to the tank during the transfer of gas into the tank without cooling, expressed in the form of an added enthalpy, cooling of the gas by the cooling component being controlled in order to remove selectively an amount of heat from the gas transferred into the tank corresponding at least to the fraction of the added enthalpy that exceeds the maximum enthalpy.
