1. A method for operating an electric vehicle (EV) propulsion system, comprising:
while a traction battery assembly is operated to transfer electric power from the traction battery assembly to a traction motor, initiating start-up of a hydrogen fuel cell assembly based on a first state of charge (SOC) threshold that corresponds to the traction battery and a first hydrogen fuel storage threshold to transition into a hybrid mode of operation;
wherein 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; and
wherein the distribution assembly is electrically coupled to the traction motor.
