Abstract

The present disclosure relates to a method and system for determining, applying, and/or managing the state-of-health of fuel cell to control the lifespan of the fuel cell in a vehicle and/or powertrain.

First claim

What is claimed is:

1. A method of controlling the lifespan of one or more power sources, the method comprising:
receiving one or more real-time inputs into a processor, the one or more real-time inputs including travel distance or travel conditions,
generating a lifespan management and control strategy by the processor using the one or more real-time inputs, the lifespan management and control strategy comprising an estimated present state-of-health and an estimated lifespan of the one or more power sources,
communicating the lifespan management and control strategy by the processor to a power source controller,
controlling power output of the one or more power sources by the power source controller based on the lifespan management and control strategy,
wherein the one or more power sources are selected from a fuel cell, a battery, and a combination thereof, and
wherein generating the lifespan management and control strategy comprises conducting an online-offline procedure including starting up one of the one or more power sources, powering the one of the one or more power sources to be operational at a first power level, allowing the one of the one or more power sources to run for a first time period at the first power level, powering the one of the one or more power sources to be operational at a second power level, and allowing the one of the one or more power sources to run for a second time period at the second power level.

2. The method of claim 1 , wherein the one or more power sources are situated on, configured to be located on, or attached to a vehicle or powertrain.

3. The method of claim 2 , wherein the vehicle or powertrain is an automobile, a truck, an aircraft, a vessel, a train, a locomotive, a bus, or mining equipment.

4. The method of claim 1 , wherein the fuel cell is a solid oxide fuel cell or a proton exchange membrane fuel cell.

5. The method of claim 1 , wherein generating the lifespan management and control strategy comprises estimating the present state-of-health of the one or more power sources.

6. The method of claim 1 , wherein conducting the online-offline procedure comprises estimating the estimated present state-of-health of the one or more power sources.

7. The method of claim 6 , wherein estimating the estimated present state-of-health of the one or more power sources comprises generating a trend line.

8. The method of claim 7 , wherein the trend line reflects the estimated lifespan of the one or more power sources.

9. The method of claim 1 , wherein controlling the power output of the one or more power sources by the power source controller comprises delivering instructions to the one or more power sources.

10. The method of claim 1 , wherein controlling the power output of the one or more power sources by the power source controller comprises extending the lifespan of the one or more power sources.

11. A system for controlling the lifespan of a power source, the system comprising:
a processor,
one or more real-time inputs based on current data, the one or more real-time inputs including travel distance or travel conditions,
a power source controller, and
one or more power sources, wherein the one or more power sources are situated on, configured to be located on, or attached to a vehicle or powertrain,
wherein the processor receives the one or more real-time inputs, uses the one or more real-time inputs to generate a lifespan management and control strategy comprising the one or more real-time inputs, an estimated present state-of-health and an estimated lifespan of the one or more power sources, and communicates the lifespan management and control strategy to the power source controller,
wherein the power source controller controls power output for the one or more power sources based on the lifespan management and control strategy, and
wherein the processor generates the lifespan management and control strategy by conducting an online-offline procedure including starting up one of the one or more power sources, powering the one of the one or more power sources to be operational at a first power level, allowing the one of the one or more power sources to run for a first time period at the first power level, powering the one of the one or more power sources to be operational at a second power level, and allowing the one of the one or more power sources to run for a second time period at the second power level.

12. The system of claim 11 , wherein each of the one or more power sources includes a separate individual controller for controlling that power source.

13. The system of claim 12 , wherein the individual controllers for each of the one or more power sources separately cooperates with the power source controller to control the power output for the one or more power sources.

14. The system of claim 11 , wherein the power output for the one or more power sources is driven by automated control.

15. The system of claim 14 , wherein the automated control of the power output of the one or more power sources is based on the lifespan management and control strategy.

16. The system of claim 11 , wherein the vehicle or powertrain is an automobile, a truck, an aircraft, a vessel, a train, a locomotive, a bus, or mining equipment.

17. The system of claim 11 , wherein the one or more power sources are selected from a fuel cell, a battery, and a combination thereof, and wherein the fuel cell is a solid oxide fuel cell or a proton exchange membrane fuel cell.

18. The method of claim 1 , wherein the one or more real-time inputs include weather data, road conditions, sea conditions, an age of the one or more power sources, or a combination thereof.

19. The system of claim 11 , wherein the one or more real-time inputs include weather data, road conditions, sea conditions, an age of the one or more power sources, or a combination thereof.
