    Abstract: An electric vehicle includes a transmission, motor, rechargeable energy storage system (RESS), auxiliary power unit (APU), and a controller. The APU has a pair of rings, at least one of which rotates with respect to the other. One ring is coaxial with and radially within the other. Ring rotation generates current in windings. A gear element is in driving connection with the rotatable ring. The APU includes an engine disposed radially within the inner ring, and a power takeoff mechanism coupled to the gear element. The controller energizes the APU to rotate a ring. A method includes positioning the APU in a vehicle body compartment, affixing an outer ring of windings to a compartment wall, and positioning a rotatable inner ring having permanent magnets radially within and coaxial with the outer ring. The engine is positioned radially within the inner ring. A power takeoff mechanism connects to the inner ring.

    Abstract: A method of managing electric power flow in a vehicle powertrain includes recording operator input indicative of a current request for electric power. An amount of the currently requested electric power corresponding with the recorded operator input is determined. This amount is averaged with amounts of requested electric power based on previously recorded operator input recorded over time. An amount of electric power required from an auxiliary power unit to satisfy the current request for electric power is determined based at least in part on the averaged requested electric power for propulsion. A powertrain has an electric motor/generator, a battery operable to provide electric power to the electric motor/generator, and an auxiliary power unit operable to supplement the battery. The auxiliary power unit includes an engine and a generator. A processor with a stored algorithm carries out the method.
