A hydrogen gas filling method includes: a step for acquiring a pre-supply upstream pressure that is a pressure in a station side of a piping at time t0, a step for starting the supply of hydrogen gas from the station at time t1 that is after the pre-supply upstream pressure is acquired, a step for acquiring a post-supply upstream pressure at time t2 that is immediate after the supply of hydrogen gas starts, a step for acquiring a start-time flowrate that is a flowrate of hydrogen gas at the same period as the step for starting, a step for estimating the pressure loss generated in the piping at the time of the supply by using the pre-supply upstream pressure, post-supply upstream pressure, and the start-time flowrate, and a step for stopping the supply of hydrogen gas so that a tank pressure conforms with a predetermined target pressure.

A method for filling a tank with pressurized gaseous hydrogen from at least one source storage containing pressurized gaseous hydrogen at a first defined temperature and at a defined pressure higher than the pressure in the tank to be filled, in which hydrogen is transferred from the source storage to the tank by pressure balancing via a filling circuit having an upstream end linked to the source storage and a downstream end linked to the tank, and in which the at least one source storage exchanges heat with a member for heating the gas stored in the source storage, during at least a part of the transfer of hydrogen from the source storage to the tank, the gas contained in the source storage being heated to a second defined temperature that is higher than the first temperature.

An integrated and mobile automatic hydrogen station achieves miniaturization by increasing space efficiency by adopting a structure that can supply high-pressure hydrogen directly from a hydrogen generating source without having a hydrogen storage tank so as to facilitate movement to sites operating hydrogen-fueled mobility products and ensure the airtightness of a gas supply path at the same time, and measures physical state variables such as pressure and temperature of gas being supplied in real time and automatically controls a supply process on the basis of the measurement so as to increase gas filling efficiency while improving safety and user convenience of a filling process.

Template data of the hydrogen dispenser related to dispensing of hydrogen by the hydrogen dispenser over a period of time is received, as well as static parameter values. One or more fill operations for dispensing hydrogen to one or more hydrogen fuel tanks may be simulated based on the template data and static parameters, as well as based on the fill control formula utilized in the hydrogen dispenser. A comparison of one or more fill operation parameter values calculated by simulating the one or more fill operations and one or more values of one or more similar fill operation parameters in the template data may be output on a user interface.

One or more computer-readable storage media storing instructions executable by one or more processors may control flow of liquid hydrogen and hydrogen gas in the system, adjust temperature of the tanks, control pressure in the tanks, and transfer hydrogen gas from the second tank, the third tank, or a combination thereof to one or more target vessels. The system may also comprise flow control assemblies and flow control valves to manage the transfer of liquid hydrogen and hydrogen gas in the system.
