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this document is to be reevaluated utilizing international field data in approximately two (2) years and subsequently superseded by SAE J2600 in the 2009 timeframe.

This SAE Information Report is intended to be used for routine (or periodic) monitoring of filling station performance. It is not intended to provide process quality control requirements for any portion of the product delivery cycle.

This SAE Technical Information Report (TIR) provides test methods for evaluating hydrogen sensors when the hydrogen system integrator and/or vehicle manufacturer elect to use such devices on board their hydrogen vehicles, including hydrogen fuel cell electric vehicles (FCEV). The tests described in 5.1 of this document are performance-based and were developed to assess hydrogen sensor metrological parameters. These tests were designed to accommodate a wide range of environmental and operating conditions based on different possible situations and sensor implementations within the vehicle. Section 5.2 covers supplemental electrical safety and physical stress tests. These are based upon standard tests developed for qualifying electrical and other components for use on vehicles and do not explicitly pertain to gas sensor metrological performance assessment.

SAE J2600 applies to the design and testing of Compressed Hydrogen Surface Vehicle (CHSV) fueling connectors, nozzles, and receptacles. Connectors, nozzles, and receptacles must meet all SAE J2600 requirements and pass all SAE J2600 testing to be considered as SAE J2600 compliant. This document applies to devices which have Pressure Classes of H11, H25, H35, H50 or H70. 1.1 Purpose SAE J2600 is intended to: • Prevent vehicles from being fueled with a Pressure Class greater than the vehicle Pressure Class; • Allow vehicles to be fueled with Pressure Class equal to or less than the vehicle Pressure Class, • Prevent vehicles from being fueled by other compressed gases dispensing stations; • Prevent other gaseous fueled vehicles from being fueled by hydrogen dispensing stations.

The purpose of this document is to provide performance requirements for hydrogen dispensing systems used for fueling 35 MPa heavy duty hydrogen transit buses and vehicles (other pressures are optional). This document establishes the boundary conditions for safe heavy duty hydrogen surface vehicle fueling, such as safety limits and performance requirements for gaseous hydrogen fuel dispensers used to fuel hydrogen transit buses. For fueling light-duty vehicles SAE J2601 should be used. SAE J2601-2 is a performance based protocol document that also provides guidance to fueling system builders, manufacturers of gaseous hydrogen powered heavy duty transit buses, and operators of the hydrogen powered vehicle fleet(s). This fueling protocol is suitable for heavy duty vehicles with a combined vehicle CHSS capacity larger than 10 kilograms aiming to support all practical capacities of transit buses.

It also describes several example fueling methods for gaseous hydrogen dispensers serving HPIT vehicles. SAE J2601-3 offers performance based fueling methods and provides guidance to fueling system builders as well as suppliers of hydrogen powered industrial trucks and operators of the hydrogen powered vehicle fleet(s). This fueling protocol for HPITs can support a wide range of hydrogen fuel cell hybrid electric vehicles including fork lifts, tractors, pallet jacks, on and off road utility, and specialty vehicles of all types. The mechanical connector geometry for H25 and H35 connectors are defined in SAE J2600 Compressed Hydrogen Surface Vehicle Refueling Connection Devices.

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.

SAE J2601 establishes the protocol and process limits for hydrogen fueling of light duty vehicles. 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 establishes standard fueling protocols based on either a look-up table approach utilizing a fixed pressure ramp rate, or a formula based approach utilizing a dynamic pressure ramp rate continuously calculated throughout the fill. Both protocols allow for fueling with communications or without communications. The table-based protocol provides a fixed end-of-fill pressure target, whereas the formula-based protocol calculates the end-of-fill pressure target continuously.

SAE TIR J2601 establishes safety limits and performance requirements for gaseous hydrogen fuel dispensers. The criteria include maximum fuel temperature at the dispenser nozzle, the maximum fuel flow rate, the maximum rate of pressure increase and other performance criteria based on the cooling capability of the station’s dispenser. This document establishes fueling guidelines for “non-communication fueling” in the absence of vehicle communication and guidelines for “communication fueling” when specified information is transmitted from the vehicle and verified at the dispenser. The process by which fueling is optimized using vehicle-transmitted information is specified. This document provides details of the communication data transmission protocol. The mechanical connector geometry is not covered in this document. SAE J2600 defines the connector requirements for fueling vehicles operating with a nominal working pressure of 35 MPa.

This Information Report provides interim background information and an interim specification of hydrogen fuel quality for commercial proton exchange membrane (PEM) fuel cell vehicles. This Report also provides background information on how this interim specification was developed by the Hydrogen Quality Task Force (HQTF) of the Interface Working Group (IWG) of the SAE Fuel Cell Standards Committee. The constituents and thresholds listed in Table 1 are based on a survey of the industry, the published literature and reflects current and draft analytical test methods. Some of the allowable constituent levels are higher than desired because a published detection method is not available for the desired threshold. Some of the allowable constituent levels may be lower than desired due to incomplete evaluations and/or an attempt to minimize testing costs (such as including methane in total hydrocarbons).

SAE J2579 is being developed by the SAE Fuel Cell Vehicle (FCV) Standards Committee to provide recommended practices for Fuel Systems in Fuel Cell and Other Hydrogen Vehicles. As part of this work, definitions for pressurized systems and containers were developed. The purpose of this document is to disseminate these definitions prior to the release of SAE J2579 such that other technical groups are aware of the information.
