Abstract

Hydrogen refueling mechanisms for fuel cell vehicles will deploy UHF (Ultra High Frequency) Wireless Communication to set up a link between H2 Refueling Station and Vehicle. Although such a technology offers a broad set of advantages (discussed later in the intellectual property), it offers a roadblock in terms of vehicle localization. In other words, a refueling station does not know which vehicle it needs to handshake with. This problem scenario becomes more challenging as more vehicles are in the station to be refueled. This paper describes a robust technology that will enable the H2 refueling station to set up a communication link and lock up with the proper vehicle. This technology will use an RSSI (Received Signal Strength Indicator) and pattern recognition based algorithm to determine the proper vehicle to be refueled. This technology will bring unparalleled robustness and intelligence in the refueling station, which will eliminate the debilitating impact of vehicle-station cross talks.

Principle of Operation:

Hydrogen refueling mechanisms for fuel cell vehicles will deploy UHF (Ultra High Frequency) Wireless Communication to set up a link between H2 Refueling Station and Vehicle. Although such a technology offers a broad set of advantages (discussed later in the intellectual property), it offers a roadblock in terms of vehicle localization. In other words, a refueling station does not know which vehicle it needs to handshake with. This problem scenario becomes more challenging as more vehicles are in the station to be refueled.  This paper describes a robust technology that will enable the H2 refueling station to set up a communication link and lock up with the proper vehicle. This technology will use an RSSI (Received Signal Strength Indicator) and pattern recognition based algorithm to determine the proper vehicle to be refueled. This technology will bring unparalleled robustness and intelligence in the refueling station, which will eliminate the debilitating impact of vehicle-station cross talks.

A brief description of the system operation is provided below.

Ø      In a scenario, when multiple fuel cell vehicles with Wireless Communication Interface Link (WCIS) will approach a single H2 refueling station, all vehicles will start communicating to the station.

Ø      The station will receive UHF signal from multiple vehicle transceiver and perform a received signal strength indication.

Ø     The RSSI signal from each vehicle will then be decoded in the fuel station transceiver embedded control system...
