Scope
SAE J2601 establishes the protocol and process limits for hydrogen fueling of light duty vehicles. These process limits (including fuel temperature, the maximum fuel flow rate, and rate of pressure increase and end pressure) are affected by factors such as ambient temperature, fuel delivery temperature and initial pressure in the vehicle’s compressed hydrogen storage system. SAE J2601-2014 establishes standard fueling protocols based on a look-up table approach with performance targets. The current standard is table-based and provides concise performance targets for both communications and non-communications fueling as described in Sections 7 through 10.
An important factor in the performance of hydrogen fueling is the station’s dispensing equipment cooling capability and the resultant fuel delivery temperature “T” rating. SAE J2601 has a reference fueling target of 3 minutes with 95-100% SOC (with communications) with a T40 rated dispenser as specified in section 6.1. However, with lower fuel delivery temperature dispenser ratings (T30 or T20) and/or at high ambient temperatures, fueling times may be longer.
SAE J2601 includes standard fueling tables for communications and non-communications fueling, as well as a non-standard, development fueling protocol. For fueling with communications, this standard is to be used in conjunction with SAE J2799, Hydrogen Surface Vehicle to Station Communications Hardware and Software. Table 1 below depicts the scope of SAE J2601-2014 and potential work items for future revisions. SAE J2601-2014 also includes, in Appendix H, a non-standard development fueling protocol called the MC Method.
SAE J2601 includes protocols for two pressure classes (35 and 70 MPa), three fuel delivery temperatures (-40 °C, -30 °C, -20 °C) and compressed hydrogen storage system sizes from 49.7 to 248.6 L. Future versions of J2601 may incorporate warmer fuel delivery temperatures (-10 °C and ambient) and smaller compressed hydrogen storage system for motorcycles.
Rationale
SAE J2601 has been updated from the original Technical Information Report (TIR) released in 2010 with technical revisions and clarifications. The updated content is based on improved fueling simulation models and has been validated through real world testing of light duty fuel cell vehicles at hydrogen stations, along with controlled lab testing. With robust correlation between these new simulations and tests, SAE J2601 is now being released as a standard for hydrogen fueling worldwide.

Issuing Committee
The Fuel Cell Standards Committee is responsible for establishing standards for hydrogen and fuel cell vehicles. Standards will cover the safety aspects of hydrogen, fuel cell, and electrical systems in the vehicle, test procedures to establish the performance of the vehicle, system/components, and interface requirements.
Reference
* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
