Abstract: A system includes an internal combustion engine including a crankshaft, a transmission including a transmission shaft, an axle, and a first electric machine rotatably coupled at least one of the crankshaft, the transmission shaft, and the axle. The first electric machine is configured to deliver rotational torque, and to generate electrical energy. The system includes an electrically-assisted turbomachine including a second electric machine configured to deliver rotational torque, and to generate electrical energy. The system includes a hybrid propulsion traction battery electrically coupled to the first and second electric machines. The hybrid propulsion traction battery is configured to deliver electrical energy to the first electric machine, and to receive electrical energy from the first and second electric machines. The system includes an electronic control unit configured to control electrical energy supplied to the first electric machine, and to control electrical energy supplied to the hybrid propulsion traction battery.
