Claim 7:
8. A method for integrated fuel cell stack and battery management system, the method comprising:
accessing a first signal from a sensor to provide a first accessed sensor signal, the sensor configured to detect an output voltage of at least one of a battery or a fuel cell, either individually or in series;
determining if the first accessed sensor signal is greater than a first threshold voltage to provide a first determination;
operably connecting the output voltage of at said at least one of said battery or said fuel cell of the battery by a plurality of system disconnects based on the first determination,
wherein the plurality of system disconnects is operably connected to the fuel cell stack and the battery, and
wherein a plurality of bypass diodes and the plurality of system disconnects are configured to selectively provide power to a propulsion inverter by at least one of the battery or the fuel cell stack, either individually or simultaneously:
accessing a second signal from the sensor to provide a second accessed sensor signal;
determining if the second accessed sensor signal is above a second threshold to provide a second determination; and
operably connecting a voltage limiting device across the output voltage of at said at least one of said battery or said fuel cell by a voltage regulating disconnect based on the second determination, wherein the voltage limiting device is configured to present an output load; and
wherein the voltage regulating disconnect is operably connected to the voltage limiting device and an output of the integrated fuel cell stack and battery management system, the voltage regulating disconnect configured to prevent an output voltage above a predetermined second threshold on said output of the integrated fuel cell stack and battery management system by switching in the voltage limiting device, based on the first accessed sensor signal.
