Diesel-Electric Hybrid

Instead, all of the energy produced from the diesel engine is converted to electric power by a generator, which recharges the energy storage device (such as a battery or bank of batteries) in order to provide power to one or more electric motors. Only the electric motor system provides torque to turn the wheels of the vehicle.
