WIP
J2799

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 protocol, SAE J2601, Compressed Hydrogen Light Duty Vehicle Fueling Protocol and SAE J2600, Compressed Hydrogen Surface Vehicle Fueling Connection Devices.

J2600
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.

Fueling Protocols for Light Duty and Medium Duty Gaseous Hydrogen Surface Vehicles

2017-04-12
WIP
J2601
SAE J2601 establishes the protocol and process limits for hydrogen fueling of light dutyand medium 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.

Gaseous Hydrogen and Fuel Cell Vehicle First and Second Responder Recommended Practice

2016-06-03
CURRENT
J2990/1_201606
Electric and alternative fueled vehicles present different hazards for first and second responders than conventional gasoline internal combustion engines. Hydrogen vehicles (H2V) including Fuel Cell Vehicles (FCVs) involved in incidents may present unique hazards associated with the fuel storage and high voltage systems. The electrical hazards associated with the high voltage systems of hybrid-electric vehicles and FCVs are already addressed in the parent document, SAE J2990. This Recommended Practice therefore addresses electric issues by reference to SAE J2990 and supplements SAE J2990 to address the potential consequences associated with hydrogen vehicle incidents and suggest common procedures to help protect emergency responders, tow and/or recovery, storage, repair, and salvage personnel after an incident has occurred. Industry design standards and tools were studied and where appropriate, suggested for responsible organizations to implement.

CURRENT
J2572_201410
This SAE Recommended Practice establishes uniform procedures for testing fuel cell and hybrid fuel cell electric vehicles, excluding low speed vehicles, designed primarily for operation on the public streets, roads and highways. The procedure addresses those vehicles under test using compressed hydrogen gas supplied by an off-board source or stored and supplied as a compressed gas onboard. This practice provides standard tests that will allow for determination of fuel consumption and range based on the US Federal Emission Test Procedures, using the Urban Dynamometer Driving Schedule (UDDS) and the Highway Fuel Economy Driving Schedule (HFEDS). Chassis dynamometer test procedures are specified in this document to eliminate the test-to-test variations inherent with track testing, and to adhere to standard industry practice for fuel consumption and range testing.
