May 5, 2010 NHA Hydrogen Conference and Expo
Background
July 2009 SAE approached CaFCP to investigate a method (hardware and signals) for Hydrogen Vehicle Authorization System
1. Provide signal for confirmation of authorization
2. Provide a means to allow for alternate fueling protocols per SAE J2601 (optional)*
3. Transmit secondary confirmation of 70 MPa (optional)
Evaluation/intermediate demonstration period
Project team formed September 2009
*Provide a path for continued development – enabling modifications for a more performance based approached 2

Hardware selection
HVAS differences from J2799 communication• Static signal at the beginning of fill
• Only provides identifier signal
Hardware requirements include• Does not require control interface from vehicle ECU
• Does not require external power source from vehicle
Options considered for HVAS hardware (non-J2799)• RFID
• Wi-Fi
• ICC
• IrDA

Concept cont’d
OEM encodes RFID with VIN (last 6 digits unique identifiers)
Central admin adds vehicle to database
Dispenser identifies vehicle from database
Non-OEM vehicle 3rd party vehicle certification
Vehicle receives fuel

Discussions
RFID location on vehicle and protocol
Reaction to unauthorized HVAS signal
Utilization of HVAS to replace PIN
Identifying central administrator
Establishing criteria for OEM HVAS signal
Finalizing fields in HVAS database

Future work
RFID placement study underway
Pilot demo to begin shortly thereafter
