Abstract:
1. A method of filling a container with gas to a pressure P 2 from at least one gas source at a pressure P 1 , P 1 being greater than P 2 , said container and said at least one gas source being connected via a line enabling the gas to pass from one to the other, the filling taking place at a flow rate which, at the end of filling, is lower than the initial flow rate, the method comprising several successive filling steps 1 to i, each of the steps being carried out with a filling flow rate D1 to Di for a time t1 to ti, i being an integer equal to or greater than 2, the flow rate of step i-1 being higher than the flow rate of step i, characterized in that the successive filling steps 1 to i are designed in terms of flow rate and duration so as to produce controlled heating of the container thereby maximizing the heat dissipation in said container without correspondingly increasing the temperature inside the container above the maximum temperature tolerated by the tank, the filling flow rate being adjusted according to the measured or estimated temperature of the container and the sum of the t i s being between 1 and 7 minutes.
