Abstract

The subject matter described herein generally relates to look ahead energy management and control systems and methods for detecting, incorporating, and leveraging look ahead technology data to improve the performance, durability, and life of fuel cell systems.

First claim

What is claimed is:

1. A look ahead energy management and control system to reduce or prevent transients in a fuel cell system, comprising:
one or more sensors operably connected to one or more data sources and configured to detect look ahead technology data related to at least one factor external to the fuel cell system,
an air handling subsystem,
the fuel cell system comprising a fuel cell stack, and
a look ahead controller,
wherein the look ahead technology data is detected by the one or more sensors and communicated to the look ahead controller which predicts transients based on the look ahead technology data,
wherein the look ahead controller proactively prompts the air handling subsystem to release excess oxygen to the fuel cell system, and the look ahead controller does not increase an amount of fuel being provided to the fuel cell system while the air handling subsystem releases the excess oxygen, and
wherein the fuel cell system reduces or prevents predicted transients of the fuel cell stack thereby extending the life of the fuel cell system.

2. The look ahead energy management and control system of claim 1 , wherein the look ahead technology data comprises information extracted from the one or more data sources selected from a group consisting of an operator or user, maps, global positioning systems (GPS), vehicle to vehicle infrastructure (V2X), dedicated short range communication (DSRC), cloud, fuel cell, vehicle controller area network (CAN), and combinations thereof.

3. The look ahead energy management and control system of claim 1 , wherein the look ahead technology data further comprises mathematical modeling data.

4. The look ahead energy management and control system of claim 1 , wherein the one or more sensors are mounted internal or external the fuel cell system.

5. The look ahead energy management and control system of claim 1 , wherein the amount of fuel being provided to the fuel cell system while the air handling subsystem releases the excess oxygen is reduced.

6. The look ahead energy management and control system of claim 1 , wherein the look ahead technology data related to the at least one factor external to the fuel cell system comprises weather.

7. The look ahead energy management and control system of claim 1 , wherein the fuel cell system is comprised in a vehicle or a powertrain, and wherein the vehicle is an electric vehicle comprising a battery.

8. The look ahead energy management and control system of claim 1 , wherein the look ahead technology data related to the at least one factor external to the fuel cell system comprises route conditions or traffic conditions.

9. A look ahead energy management and control system to extend the life of a fuel cell system, comprising:
one or more sensors configured to detect look ahead technology data,
an air handling subsystem including a compressor,
a battery,
the fuel cell system comprising a fuel cell stack, and
a look ahead controller,
wherein the look ahead technology data is detected by the one or more sensors and communicated to the look ahead controller which predicts transients based on the look ahead technology data,
wherein the look ahead controller is programmed to determine an optimal power split between the fuel cell system and the battery based on the look ahead technology data so that a first power demand is provided by the fuel cell system and a second power demand is provided by the battery,
wherein the look ahead controller proactively prompts the air handling subsystem to release excess oxygen to the fuel cell stack of the fuel cell system,
wherein the compressor is spooled up to a desired pressure and flow point to increase a mass flow rate of air flowing through the fuel cell system as a precharge for the fuel cell system,
wherein the look ahead controller is programmed to reduce the second power demand provided by the battery in response to predicted transients based on the look ahead technology data, and
wherein the fuel cell system reduces or prevents predicted transients, powercycling, or parasitic load of the fuel cell stack thereby extending the life of the fuel cell system.

10. The look ahead energy management and control system of claim 9 , wherein the look ahead technology data comprises information extracted from a source selected from a group consisting of maps, global positioning systems (GPS), vehicle to vehicle infrastructure (V2X), dedicated short range communication (DSRC), cloud, vehicle controller area network (CAN), and combinations thereof.

11. The look ahead energy management and control system of claim 9 , wherein the look ahead technology data further comprises mathematical modeling data.

12. The look ahead energy management and control system of claim 9 , wherein the one or more sensors are mounted internal or onboard the fuel cell system.

13. The look ahead energy management and control system of claim 9 , wherein the precharge for the fuel cell system occurs in anticipation of an event during operation of the fuel cell system that requires an increase in power demand of the fuel cell system.

14. The look ahead energy management and control system of claim 9 , wherein the fuel cell system is comprised in a vehicle or a powertrain.

15. The look ahead energy management and control system of claim 14 , wherein the vehicle is an electric vehicle.

16. The look ahead energy management and control system of claim 9 , wherein stored energy is used to spool up the compressor, the stored energy is obtained from a secondary source.

17. A look ahead energy management and control system to reduce or prevent transients in a fuel cell system, comprising:
one or more sensors operably connected to one or more data sources and configured to detect look ahead technology data related to one or more inputs comprising locations of fill up stations, locations of charging stations, weather, and combinations thereof,
an air handling subsystem,
the fuel cell system comprising a fuel cell stack, and
a look ahead controller,
wherein the look ahead technology data is detected by the one or more sensors and communicated to the look ahead controller which predicts transients based on the look ahead technology data,
wherein the look ahead controller proactively prompts the air handling subsystem to release excess oxygen to the fuel cell system, and the look ahead controller does not increase an amount of fuel being provided to the fuel cell system while the air handling subsystem releases the excess oxygen, and
wherein the fuel cell system reduces or prevents predicted transients of the fuel cell stack thereby extending the life of the fuel cell system.

18. The look ahead energy management and control system of claim 17 , wherein the look ahead technology data comprises information extracted from the one or more data sources selected from a group consisting of maps, global positioning systems (GPS), vehicle to vehicle infrastructure (V2X), dedicated short range communication (DSRC), cloud, vehicle controller area network (CAN), and combinations thereof.

19. The look ahead energy management and control system of claim 17 , wherein the one or more sensors comprises a GPS sensor.

20. The look ahead energy management and control system of claim 17 , wherein the one or more sensors comprises a camera.
