The heat transfer analysis in the filling process of compressed on-board hydrogen storage tank has been the focus of hydrogen storage research. The initial conditions, mass flow rate and heat transfer coefficient have certain influence on the hydrogen filling performance.
The fast filling process is completed at the hydrogen refueling station. The high-pressure gas reaches the on-board hydrogen tank from the hydrogen refueling station storage tank through the throttle valve. The schematic of the fast filling process is shown in Fig. 1.
For convenience, it is also necessary to control the filling time. The United States Department of Energy (DOE) set a technical system target of 3.3 min of filling time for the 5 kg hydrogen storage system to be achieved in 2020 [ 7 ].
The study shows that a cascade filling system can well refuel the on-board storage tank with constant average pressure ramp rate (APRR). Furthermore, a strong pre-cooling system can effectively lower the final temperature at a cost of larger energy consumption.
The two codes stipulate the requirement for the hydrogen refueling station to safely fill various types of on-board hydrogen storage tanks, and can guarantee the completion of filling within 3–5 min. The cascade filling system generally consists of 2–4 pressure levels of hydrogen storage tanks.
