Description
Summary:The hydrogen fuel filling time for hydrogen-powered fuel cell electric vehicles at different initial conditions was estimated through dynamic simulation by using Aspen Dynamics v.11 with Peng-Robinson as the thermodynamic model. The simulation process was divided into three parts, in which the different storage vessels (LP, MP, and HP banks) act as the sole hydrogen source. The SAE J2601 standard was used as the basis for the fueling operation. For the fast filling of the car tank with hydrogen gas, a detailed heat transfer modeling suited for the process was elaborated to correctly predict the in-cylinder temperature throughout the fueling operation. During the dynamic simulation, the station pressure, the state-of-charge %, the car tank temperature, the hydrogen flow rate, the amount of hydrogen gas accumulated in the car tank, and the high-pressure storage vessels’ conditions were monitored and confirmed according to their expected values or limits. It is determined that the fueling times calculated in the dynamic study were faster than their corresponding estimated values for all cases, indicating the integrity of the process.
