Device and method for filling tanks

A device for filling pressurized-gas tanks, comprising an electronic controller and a fluid transfer circuit that comprises an upstream end intended to be connected to a source of gas and at least two parallel downstream ends adapted and configured to be connected to distinct tanks that are to be filled, wherein:

• the transfer circuit further comprises a temperature regulating member for regulating a temperature of the gas that is transferred from the source towards the downstream ends;
• the gas temperature regulating member is positioned in the transfer circuit upstream of the at least two downstream ends such that the gas temperature regulating member is common to the at least two downstream ends;
• each of the at least two downstream ends of the circuit comprises a respective pressure-control and/or flow rate-control valve that is adapted to independently control a pressure or flow rate of the transferred gas in a respective one of the downstream ends;
• and
• the electronic controller is adapted and configured to control each of said pressure-control and/or flow rate-control valve according to one or more quick-fill algorithms establishing identical or distinct respective rates of pressure increase in the said tanks.
