Refuelling
Safety
WARNING!
Leaks in the hydrogen supply in combination with an ignition source pose a risk of
fire, explosion or suffocation.
The hydrogen refuelling system must therefore be approved by the manufacturer, set up
in compliance with the applicable standards and guidelines and operated in accordance
with the manufacturer's instructions. Refuelling must only be carried out by suitably trained
personnel. The technical data shown on the rating plate applies. The additional instructions
in the following sections of this chapter must be observed.
WARNING!
Overfilling the hydrogen tank poses a risk of explosion and can result in serious in-
juries and damage.
The refuelling process must be carried out according to the SAE J2601-3 parameters and
the refuelling guideline of the HyLOG Fleet unit. Do not exceed the indicated fuelling rate,
as well as the nominal pressure of 350 bar (5074.55 psi.) at 15 °C (59 °F) and the maximum
filling pressure of 438 bar (6350.43 psi.) at 85 °C (1232.39 °F).
General
WARNING!
Failure to adhere to the specified fuelling parameters could result in serious injury
or damage.
The specified fuelling parameters must be observed at all times.
-
The HyLOG Fleet system may only be refuelled in accordance with the refuelling
guidelines.
-
The fuelling system and the fuelling process must be compliant with SAE J2601-
3:JUN2013.
-
The nominal pressure of the HyLOG Fleet system is 350 bar (5074.55 psi) at 15 °C
(59 °F). The maximum filling pressure is 438 bar (6350.43 psi) at 85 °C (185 °F).
-
The hydrogen temperature stated in the tables below (Hydrogen Temperature, T
gas
)
refers to the temperature of the hydrogen output by the fuelling system.
-
The specified pressure ramp rates must be observed without exception!
-
The pressure ramp rates are based on a maximum hydrogen temperature of 85 °C
(185 °F) inside the HyLOG Fleet system.
General refuelling
-
The HyLOG Fleet system must be refuelled at no more than the specified pressure
ramp rates (Average Pressure Ramp Rate, APRR) in accordance with the hydrogen
temperature of the refuelling system.
-
The target pressure (Fuelling Target Pressure) must be observed at all times.
Example: A gas temperature ≤ 25 °C (77 °F) and an initial pressure of 2.5 MPa (25 bar)
(362.47 psi) translates into a permissible pressure ramp rate of 14.0 MPa/min (140 bar/
min) (2029.82 psi/min). The maximum filling pressure is 42.5 MPa (425 bar) (6161.95 psi).
