This standard specifies the communications hardware and software requirements for fueling hydrogen surface vehicles (HSV), such as fuel cell vehicles, but may also be used where appropriate, with heavy-duty vehicles (e.g., busses) and industrial trucks (e.g., forklifts) with compressed hydrogen storage. It contains a description of the communications hardware and communications protocol that may be used to refuel the HSV. The intent of this standard is to enable harmonized development and implementation of the hydrogen fueling interfaces.This standard is intended to be used in conjunction with the hydrogen fueling protocols in SAE J2601 and J2601/5, and nozzles and receptacles conforming with SAE J2600.

This technical information report specifies a guideline for the hardware requirements for fueling a Hydrogen Surface Vehicle (HSV) with compressed hydrogen storage rated at a Nominal Working Pressure of 70 MPa. It contains a description of the receptacle geometry and optional communication hardware and communications protocol to refuel the HSV. The intent of this document is to enable harmonized development and implementation of the hydrogen fueling interfaces. It is intended to be utilized for hydrogen vehicle field evaluations until enough information is collected to enable standardization. The receptacle portion of this document is to be reevaluated utilizing international field data in approximately two (2) years and subsequently superseded by SAE J2600 in the 2009 timeframe.
