- Content
- 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., buses) 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.
- Content
- This document has a new communication protocol version number 2.00 for high flow fueling protocols, such as SAE J2601/5. This includes a larger TV range and structured formatting rules in order to send additional information in the OD field. The geometry requirements for the IrDA hardware are adjusted for larger receptacle/nozzles.
