Method for filling a tank with pressurized gas

摘要

The invention relates to a method for filling a tank with pressurized gas, particularly hydrogen in the tank of a vehicle, using a filling station that comprises: a plurality of buffer containers for containing the pressurized gas and filling the tank through successive pressure balancing phases; a device for generating a pressurized gas and for filling said buffer containers from a fluid source; wherein the method comprises a tank filling step by gas transfer from a buffer container and simultaneously by gas transfer directly from the source via the gas generation device, characterized in that the pressurized-gas generation device includes a compressor connected to the buffer containers and in that the compressor supplies gas to the tank from a gas source including a first buffer container for at least part of a pressure balancing phase between at least one second buffer container and a tank, the buffer containers being successively used as sources by the compressor after being used for pressure balancing with the tank.

1. A method for filling a tank with pressurized gas at a filling station, the filling station having (a) a plurality of buffer containers containing pressurized gas and (b) a pressurized gas generation device for generating a pressurized gas from a fluid source, the pressurized gas generation device including a compressor connected to the plurality of buffer containers, the method comprising the step of:
simultaneously filling the tank by gas transfer from a buffer container and by gas transfer directly from the fluid source via the pressurized gas generation device, wherein the compressor supplies pressurized gas to the tank from the fluid source including a first buffer container during at least part of a pressure balancing phase between at least one second buffer container and the tank, each of the plurality of buffer containers being successively used as the fluid source by the compressor after being used for pressure balancing with the tank.
