Abstract

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.

First claim

What is claimed is:

1 . A method of refueling a vehicle comprising:
conducting a safety check on the vehicle based on a distance between the vehicle and a refueling station, switching a power source of the vehicle to only comprise a battery, swapping an empty or partially filled vehicle fuel tank with a filled station fuel tank at the refueling station, switching the power source of the vehicle to include a hydrogen power source, and enabling a vehicle cooling system to cool the empty or partially filled vehicle fuel tank before swapping the empty or partially filled vehicle fuel tank with the filled station fuel tank.

2 . The method of claim 1 , further comprising identifying a swap location located in the refueling station for refueling, wherein the filled station fuel tank is located at the swap location in the refueling station.

3 . The method of claim 2 , wherein swapping the empty or partially filled hydrogen fuel tank comprises
disconnecting the empty or partially filled vehicle fuel tank from the vehicle, removing the empty or partially filled vehicle fuel tank from the vehicle with a lifting equipment, moving the filled station fuel tank from the swap location into the vehicle with the lifting equipment, and aligning the filled station fuel tank in the vehicle.

4 . The method of claim 2 , further comprising syncing one or more sensors in the swap location to one or more sensors on the vehicle.

5 . The method of claim 4 , further comprising enabling autonomous drive control of the vehicle before swapping the empty or partially filled vehicle fuel tank and enabling operator control of the vehicle after switching the power source of the vehicle to include the hydrogen power source.

6 . The method of claim 1 , wherein conducting the safety check comprises purging hydrogen from a hydrogen line in the vehicle and disconnecting electrical connections from the hydrogen line in the vehicle before swapping the empty or partially filled vehicle fuel tank with the filled station fuel tank.

7 . The method of claim 6 , further comprising reconnecting the hydrogen line in the vehicle and purging the hydrogen line in the vehicle before swapping the empty or partially filled vehicle fuel tank with the filled station fuel tank.

8 . The method of claim 2 , further comprising providing the vehicle with a lifting equipment, wherein the lifting equipment is located at the identified swap location before swapping the empty or partially filled vehicle fuel tank with the filled station fuel tank.

9 . The method of claim 1 , wherein identifying the refueling station, conducting the safety check on the vehicle, switching the power source of the vehicle to the battery, swapping the empty or partially filled vehicle fuel tank on the vehicle with the filled station fuel tank, or switching the power source of the vehicle to the hydrogen power source is automatically performed by a controller.

10 . The method of claim 1 , wherein the method further comprises charging the battery or swapping the battery for a different battery.

11 . The method of claim 1 , further comprising refilling a first empty or partially filled vehicle fuel tank on the vehicle and swapping a second empty or partially filled vehicle fuel tank with the filled station fuel tank at the refueling station.

12 . A system for refueling a vehicle comprising:
one or more vehicle fuel tanks on the vehicle, a refueling station with a swap location, a hydrogen-filling site, one or more station fuel tanks filled with hydrogen and positioned at the swap location or at the hydrogen-filling site, a vehicle cooling system to cool one or more vehicle fuel tank before swapping the one or more vehicle fuel tanks with the one or more station fuel tanks filled with hydrogen, and a system controller configured to be in communication with the refueling station, the swap location, and the hydrogen-filling site.

13 . The system of claim 12 , wherein the system further comprises a hydrogen storage location and the system controller is configured to determine a transfer of hydrogen from the hydrogen storage location to the hydrogen-filling site through a pipeline infrastructure.

14 . The system of claim 13 , wherein one or more empty station fuel tanks are filled with hydrogen at the hydrogen-filling site through a quick connect mechanism.

15 . The system of claim 12 , wherein the vehicle further comprises a sensor to determine a pressure of the one or more vehicle fuel tanks, an identifier on the one or more vehicle fuel tanks, and a vehicle controller configured to communicate the pressure of the one or more vehicle fuel tanks and the identifier on the one or more vehicle fuel tanks to the system controller.

16 . The system of claim 15 , wherein the system controller is configured to determine if the swap location includes one or more station fuel tanks compatible with the identifier on the one or more vehicle fuel tanks.

17 . The system of claim 12 , wherein the one or more vehicle fuel tanks are swapped with the one or more station fuel tanks at the swap location.

18 . The system of claim 17 , wherein one or more empty or partially filled vehicle fuel tanks are swapped with full station fuel tanks at the swap location or filled with hydrogen at the swap location.

19 . The system of claim 12 , wherein the swap location further comprises a lifting equipment to move and align the one or more station fuel tanks onto the vehicle.

20 . A method of refueling a vehicle comprising:
conducting a safety check on the vehicle based on a distance between a vehicle and the refueling station, switching a power source of the vehicle to only comprise a battery, swapping an empty or partially filled vehicle fuel tank with a filled station fuel tank at the refueling station, switching the power source of the vehicle to include a hydrogen power source, and syncing one or more sensors in a swap location located in the refueling station to one or more sensors on the vehicle, wherein the filled station fuel tank is located at the swap location.
