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.
