  • Publication number: 20220348113
    Abstract: Methods and systems for an electric vehicle (EV) propulsion are provided. A method for operating an EV propulsion system is provided, in one example, that includes, while a traction battery assembly generates electric power, initiating start-up of a hydrogen fuel cell assembly based on a first battery state of charge (SOC) threshold and a first hydrogen fuel storage threshold to transition into a hybrid mode of operation. In the propulsion system, the traction battery assembly includes one or more traction batteries that are electrically coupled to one or more hydrogen fuel cells in the hydrogen fuel cell assembly via a distribution assembly, where the distribution assembly is electrically coupled to a traction motor.

  • Publication number: 20220348111
    Abstract: Methods and systems are provided for cooling a hydrogen fuel cell assembly. A vehicle system, in one example, includes a hydrogen fuel cell assembly electrically coupled to a traction motor, positioned behind a cab, and including a plurality of hydrogen storage tanks and hydrogen fuel cells. The vehicle system further includes a fuel cell cooling assembly including an inlet manifold in a deflector, where the deflector is fixedly coupled to and positioned vertically above the cab and designed to direct airflow to a fan array that is coupled to a fuel cell assembly heat exchanger, where the fan array is positioned behind inlet manifold and longitudinally offset therefrom.

  • Publication number: 20220348112
    Abstract: Methods and systems are provided for an electric vehicle powertrain. The vehicle system includes an electric distribution assembly with a junction box that is electrically coupled to a traction motor-generator and is designed to electrically coupled to, via separate circuits, a traction battery assembly and a hydrogen fuel cell assembly that is positioned behind a vehicle cab. In the system, the traction battery assembly is positioned vertically below the hydrogen fuel cell assembly.
