In the present invention, the refueling station can directly and accurately calculate the temperature at the end of refueling in the hydrogen tank, improving the refueling quality, while tending to reduce the refueling time. Clarify the method. The calculation includes the calculation of the combined heat capacity value (MC) based on the thermodynamic parameter set obtained from the tank system receiving the gas and the station supplying the gas. These thermodynamic parameters are used in a series of simple analytical equations to define a multi-stage process and determine the target refill time, final temperature and final pressure. The parameters are either communicated directly from the vehicle to the station or retrieved from a database accessible from the station. Since this method is based on direct measurement of actual thermodynamic conditions and quantified thermodynamic behavior, tank refueling results are greatly improved. |
