Abstract: A vehicle energy management and storage system has a first connection from a crank battery to a first breaker, a second connection for the breaker to a DC-DC battery charger, a third connection from the DC-DC battery charger to second breaker, and a fourth connection from the second breaker to one or more storage batteries. The storage batteries are electrically coupled, through a fuse, to a power inverter for inverting 12V DC to 110 AC, which supplies AC power to an outlet. This allows a user to capture, store, and utilize excess energy generated by a vehicle alternator, and in some examples, solar panels.

Abstract: Described is a hybrid permanent magnet and wire wound starter generator system. The system includes a polyphase stator that converts a rotating magnetic field to electrical energy. The system also includes a rotor including a plurality of permanent magnets and a wound rotor section. The plurality of permanent magnets and the wound rotor section each generate a portion of the rotating magnetic field. Further, the system includes a controller that controls a polarity of the wound rotor section by transitioning the wound rotor section between a magnetic flux enhancement mode and a magnetic flux weakening mode.

Abstract: Methods and apparatus provide for commutating windings of a polyphase machine such that electromagnetic fields of stator and rotor phases of the polyphase machine produce at least one of motoring and generating torque, wherein the controller is operable to automatically vary at least one of a lead angle measured between the electromagnetic fields of the stator and rotor phases and rotor excitation parameters as a function of a rotational speed of the polyphase machine.

Abstract: Methods and apparatus provide for: commutating windings of a polyphase machine such that electromagnetic fields of stator and rotor phases of the polyphase machine produce at least one of motoring and generating torque; providing a first rotor excitation voltage having substantially no DC component when a rotational speed of the polyphase machine is below a predetermined value; and providing a second rotor excitation voltage having a DC component when the rotational speed of the polyphase machine is above the predetermined value.
