Abstract: Described is a method of charging a sorption store with a gas. The sorption store comprises a closed container and a feed device which has a passage through the container wall, through which the gas can flow into the container, and the container has at least two parallel, channel-shaped subchambers which are located in its interior and are each at least partly filled with an adsorption medium and whose channel walls are coolable. The method comprises, in a first step, feeding in a gas in such an amount that a pressure in the store of at least 30% of a predetermined final pressure is reached as quickly as possible and, in a second step, subsequently varying the amount of gas fed in in such a way that the course of the pressure in the store approximates the adsorption kinetics of the adsorption medium until the predetermined final pressure in the store is reached after a predetermined period of time.
