1. A pressurized gas container, comprising an internal volume for storing gas under pressure, comprising: a fluid-distributing valve; a pressure sensor for measuring the pressure of the gas and for supplying at least one measurement signal; and a microprocessor-based control means configured to process said at least one measurement signal supplied by the pressure sensor and to determine at least one measured pressure value; wherein the microprocessor-based control means are configured to: detect filling of the gas container with gas, by comparing said at least one measured pressure value with at least one predefined and stored reference pressure threshold value, and initiate a timer on the basis of a detection of filling of the gas container with gas.
