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.
