Feasibility Investigation of Hydrogen Vehicle Authorization System for Hydrogen Fueling Jacquelyn Button California Fuel Cell Partnership 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 • Provide signal for confirmation of authorization • Provide a means to allow for alternate fueling protocols per SAE J2601 (optional)* • 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
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 Vehicle receives fuel Non-OEM vehicle 3rd party vehicle certification
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 • Analysis of pilot demo and recommendations to SAE by EOY 2010
