Abstract
A vehicle includes a first prime mover and a first prime mover driven transmission. A vehicle drive system for the vehicle includes an electric energy source, an electric motor in direct or indirect mechanical communication with the first prime mover, and a high power generator coupled to the electric motor. The electric motor is configured to generate energy for storage in the energy source via rotation using power from the first prime mover and drives the generator using energy from the electric energy source.
