Abstract: A method of controlling the ventilation system for an energy source in a fuel cell vehicle is disclosed, which includes an HVAC system, a fluid reserve, and a rechargeable energy storage system (RESS), capable of controlling a temperature of the RESS to militate against damage to or a shortened life of the battery, while maximizing vehicle durability, efficiency, performance, and passenger comfort.

Abstract: A system and method for managing power flow in a fuel cell vehicle. The method provides a difference between a power limit signal and an actual power signal to a PI controller to generate a power offset signal. The method determines whether a fuel cell stack is able to provide enough power to satisfy a power request, and if so, adds the power request and the power offset signal to generate a stack power request signal to cause the upper power limit signal to move towards and be matched to the actual power signal. If the stack is not able to provide enough power to satisfy the load power request signal, the method subtracts the power offset signal from the power limit signal to provide a load limit signal to cause the actual stack power signal to move towards and be matched to the upper power limit signal.

Abstract: Systems and methods are provided for regulating the state of charge of a battery. An exemplary electrical system includes a fuel cell coupled to a bus and a battery coupled to the bus via a switching arrangement coupled to a capacitor. An exemplary method for operating the electrical system involves operating the switching arrangement such that a voltage of the battery is substantially equal to a voltage of the fuel cell when a state of charge of the battery is greater than a lower threshold value and less than an upper threshold value, and operating the switching arrangement to couple the capacitor electrically in series between the battery and the bus when the state of charge of the battery is not between the lower threshold value and the upper threshold value.
