Systems and methods for integrated fuel cell stack and battery management for transportation use

An integrated fuel cell power delivery system, the system comprising:

• a first power source configured to supply power to a propulsion inverter;
• a second power source configured to supply power to the propulsion inverter;
• an electronic voltage limiting device configured to selectively provide a load on at least one of the first power source or second power source;
• a sensor that detects an output voltage of the integrated fuel cell power system;
• a processor;
• and
• a memory, which includes instructions stored thereon, which when executed by the processor, cause the integrated fuel cell power system to:
• access a first signal from the sensor;
• determine if the accessed first signal is greater than a threshold voltage;
• and
• selectively provide a load, by the electronic voltage limiting device, to at least one of the first power source or second power source based on the determination;
• the system further comprising an electronic voltage limiting device configured to selectively provide a load on at least one of the first power source or second power source;
• wherein the instructions, when executed by the processor, further cause the integrated fuel cell power system to:
• access the signal from the sensor;
• determine if the accessed first signal is greater than a third threshold voltage;
• and
• selectively provide a load, by the electronic voltage limiting device, to at least one of the first power source or second power source based on the determination,
• wherein the voltage limiting device includes a calibrated load configured to load the output of the integrated fuel cell power system in a case where the output voltage exceeds the predetermined third threshold voltage.

A computer-implemented method for integrated fuel cell stack and battery management, the method comprising:

• accessing a signal from a sensor, the sensor configured to detect an output voltage of at least one of a first power source or a second power source, either individually or in series;
• determining if the accessed sensor signal is greater than a first threshold voltage;
• and
• operably disconnecting an output of the second power source by a power source disconnect based on the determination,
• wherein the power source disconnect is operably connected to the second power source,
• wherein a plurality of bypass diodes and the power source disconnect are configured to selectively provide power to a propulsion inverter by at least one of the first power source or the second power source, either individually or simultaneously;
• accessing the signal from the sensor;
• determining if the accessed signal is greater than a third threshold voltage;
• and selectively providing a load, by an electronic voltage limiting device, to at least one of the first power source or second power source based on the determination,
• wherein the electronic voltage limiting device is configured to selectively provide a load on at least one of the first power source or second power source, and
• wherein the voltage limiting device includes a calibrated load configured to load the output of the integrated fuel cell power system in a case where the output voltage exceeds the predetermined second threshold voltage.
