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.
Claims19
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.

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.
