Scope |
SAE J2601/4 establishes the
protocol and process limits for hydrogen fueling of light duty vehicles when the
fuel delivery temperature is not pre-cooled, so called “ambient fueling”
designated by Table 1 of SAE J2601-2014. These process limits (including the
fuel delivery temperature, the maximum fuel flow rate, the rate of pressure
increase and the ending pressure) are affected by factors such as ambient
temperature, fuel delivery temperature and initial pressure in the vehicle’s
compressed hydrogen storage system. SAE J2601/4 establishes standard
fueling protocols based on a series of design cases representing fueling
system engineering categories. These categories are intended to provide
performance targets which allow decreasing fueling times relative to the most
simple design case. Similar to the table and formula based approaches of SAE
J2601-2014, this approach establishes a minimum performance criteria leaving
open options for innovation to decrease fueling times. |

Under
development.
After delays, expect document will be ready for voting in the 3rd
quarter of 2022. The Committee is currently working to resolve comments to an
early draft (May ’22). |
