Original Abstract Submitted
A motor vehicle includes an AC (alternating current) electric motor having a stator with a plurality of stator windings, a rechargeable source of stored electrical energy, and an inverter coupled to the rechargeable source of stored electrical energy and to the AC electric motor. The system also includes one or more controllers collectively programmed to switch the inverter to provide alternating current propulsive energy from the rechargeable source of stored electrical energy to the plurality of stator windings and, using at least one of the stator windings as a boost inductor, switch the inverter to step up a voltage at a charging input coupled to the inverter to charge the rechargeable source of stored electrical energy.
