FUEL REFILLING SYSTEM AND METHOD FOR EQUIPMENT POWERED BY FUEL
The present disclosure relates to systems and methods for optimizing refueling hydrogen in vehicles. Specifically, the present disclosure relates to identifying a refueling station, conducting a safety check on the vehicle based on a distance between the vehicle and the refueling station, switching a power source of the vehicle to only be a battery, swapping an empty or partially filled hydrogen fuel tank on the vehicle with a filled or partially filled hydrogen fuel tank at the refueling station, and switching the power source of the vehicle to include a hydrogen power source.
1 . A vehicle system comprising:
a vehicle fuel tank on the vehicle;
a vehicle cooling system to cool the vehicle fuel tank;
an identifier on the vehicle fuel tank; and
a system controller operable to determine if the vehicle fuel tank can be swapped based on the identifier on the vehicle fuel tank.
2 . The system of claim 1 , wherein the system controller is configured to determine if a refueling station includes a station fuel tank compatible with the identifier on the vehicle fuel tank.
3 . The system of claim 1 , wherein the vehicle system comprises a first refueling equipment located on a first side of the vehicle and a second refueling equipment located on a second side of the vehicle.
4 . The system of claim 1 , wherein the vehicle system comprises at least one vehicle fuel tank located on a first side of the vehicle and at least one vehicle fuel tank located on a second side of the vehicle.
5 . The system of claim 4 , wherein the vehicle system comprises a first fuel tank assembly located on the first side of the vehicle and a second fuel tank assembly located on the second side of the vehicle, wherein the first fuel tank assembly and the second fuel tank assembly can be removed and reinstalled as a single unit.
6 . The system of claim 1 , wherein the system controller is operable to implement a quick-swap to replace an empty vehicle fuel tank or a partially filled vehicle fuel tank in the vehicle with a fully filled station fuel tank in a refueling station when the identifier on the vehicle fuel tank is compatible with the station fuel tank.
7 . The system of claim 6 , wherein the empty vehicle fuel tank contains 10% or less of fuel, the partially filled vehicle fuel tank comprises between 10% and 90% of fuel, and the fully filled vehicle station fuel tank comprises more than 90% of fuel.
8 . The system of claim 1 , wherein the vehicle fuel tank comprises hydrogen, natural gas, or diesel.
9 . The system of claim 1 , wherein the vehicle is configured so that the vehicle fuel tank is accessible, removable, and replaceable from outside the vehicle.
10 . The system of claim 1 , wherein the vehicle comprises one to twenty vehicle fuel tanks.
11 . A swapping fuel tank system comprising:
a vehicle with a vehicle fuel tank and an additional power source;
a refueling station with a swap location;
a station fuel tank located at the swap location; and
a system controller configured to be in communication with the refueling station and the swap location.
12 . The system of claim 11 , wherein the additional power source is a battery.
13 . The system of claim 11 , wherein the system controller is operable to implement a quick-swap to replace an empty vehicle fuel tank ora partially filled vehicle fuel tank in the vehicle with a fully filled station fuel tank in a refueling station when an identifier on the vehicle fuel tank is compatible with the station fuel tank.
14 . The system of claim 13 , wherein the vehicle is powered by the additional power source when the quick-swap is implemented.
15 . The system of claim 13 , wherein the empty vehicle fuel tank contains 10% or less of fuel, the partially filled vehicle fuel tank comprises between 10% and 90% of fuel, and the fully filled vehicle station fuel tank comprises more than 90% of fuel.
16 . The system of claim 11 , wherein the vehicle fuel tank comprises hydrogen, natural gas, or diesel.
17 . The system of claim 11 , wherein the vehicle further comprises a sensor to determine a pressure of the vehicle fuel tank.
18 . The system of claim 17 , wherein the vehicle further comprises a vehicle controller configured to communicate the pressure of the vehicle fuel tank to the system controller.
19 . The system of claim 13 , wherein one or more empty station fuel tanks are filled with hydrogen at a hydrogen-filling site through a quick-connect mechanism.
20 . The system of claim 11 , wherein the swap location further comprises a lifting equipment configured to move and align a station fuel tank onto the vehicle.
