Organization: SAE
Publication Date: 1 December 2019
Status: active
Page Count: 33
scope:

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 nozzles and receptacles conforming with SAE J2600.

Gaseous Hydrogen Fueling System Background

The overall hydrogen fueling system consists of a dispenser, HSV, and hydrogen fueling coupling. The nozzle and receptacle mechanically couples the hydrogen fueling system (dispenser) and the HSV, and allows hydrogen gas to flow between them. The interface between the two is defined as the fueling interface. The data is transmitted from the IR transmitter on the HSV to the IR (infrared) receiver on the dispenser.
