Mobile Refueling and Its Information Infrastructure

Presently roadside assistance includes a vehicle refueling service on the side of the road using portable fuel canisters filled with gasoline. With the increased popularity of electric vehicles, an analogous service for recharging propulsion batteries is being introduced as part of roadside assistance programs. For charging of an electric vehicle, usually a bidirectional charging cable is used. For gaseous fuels (e.g. propane, natural gas or hydrogen), this roadside refueling service is only available from tanker-based service vehicles. Aside from a roadside service, drivers of these vehicles fail to benefit from the typical fellow driver with a portable fuel canister like stranded drivers of gasoline vehicles often do in time of need.

We propose a "smart" refueling hose that plugs into the defuel port of a donor vehicle and the refuel port of stranded vehicle (as shown in Figure 1). Although the function and operation of this device is explained for a hydrogen fuel cell application, the same approach can be applied to other gaseous fuels such as propane or natural gas. This "smart" refueling hose continuously verifies a secure connection to both ports, then commands the tank valve of the stranded car to open (wirelessly, via OBDII, or some other method). The de-fuel valve (3-way manual diverter valve) of the donor vehicle is opened (wirelessly, via OBDII, manually or by some other method) to begin roadside ass...
