High reliability hybrid energy storage system

A system, comprising:

• a first battery circuit;
• a second battery circuit;
• a fuel cell stack;
• a traction motor;
• and
• an operating system configured to:
• command the system to power the traction motor via the first battery circuit,
• reconfigure the system to electrically couple the first battery circuit to the fuel cell;
• stack and to electrically couple the second battery circuit to the traction motor,
• command the fuel cell stack to charge the first battery circuit, and
• command the second battery circuit to power the traction motor.

An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon that, in response to execution by an operating system, cause the operating system to perform operations comprising:

• commanding, via the operating system, a first battery circuit to power a traction motor;
• reconfiguring, via the operating system, the first battery circuit to be electrically coupled to a fuel cell stack and a second battery circuit to be electrically coupled to the traction motor;
• commanding, via the operating system, the second battery circuit to power the traction motor;
• and
• commanding, via the operating system, the fuel cell stack to charge the second battery circuit.

An article of manufacture including a tangible, non-transitory computer-readable storage medium having instructions stored thereon that, in response to execution by an operating system, cause the operating system to perform operations comprising:

• configuring, via the operating system, a first battery circuit having at least two first batteries in a series configuration and electrically coupling the first battery circuit to a traction motor;
• configuring, via the operating system, a second battery circuit having at least two second batteries in a parallel configuration and electrically coupling the second battery circuit to a fuel cell stack;
• commanding, via the operating system, the at least two first batteries to power the traction motor;
• and
• commanding, via the operating system, the fuel cell stack to charge the at least two second batteries.
