Communication method between hydrogen fueling station and vehicle
A recently granted patent (Publication Number: US11926237B2) outlines a method for communication between a hydrogen fueling station and a hydrogen-powered vehicle with a fueling system comprising two hydrogen tanks. The method involves establishing an NFC link between the station and the vehicle, transmitting identifying information, selecting a V2X communication network, and delivering pressurized hydrogen to fill the tanks. Additional steps include communicating tank information, monitoring tank data during fueling, and stopping delivery if tank conditions are out of bounds. The communication links are rated at an ASIL D level of safety, and various information such as fueling protocols, payment details, and software updates can be exchanged between the station and the vehicle.
Furthermore, the method involves updating fueling protocols based on monitoring data, exchanging payment information, downloading diagnostic information from the vehicle, and completing delivery in case of communication interruptions. The communication protocols used include NFC standards and V2X protocols like IEEE 802.11, 4G LTE, or 5G mobile networks. The NFC hardware used is replaceable without affecting the nozzle's function, and hydrogen can be delivered simultaneously to both tanks. The station also polls the vehicle for tank information at short intervals during fueling, and the NFC hardware is rated for use in a Zone 1 hydrogen classified area, with a specified distance of 20 centimeters or less for establishing the NFC link.
