Abstract: A system for storing input power and providing output power, such as for use with electric vehicle charging, can include an alternating current motor, a flywheel, an alternating current generator, or any combination thereof. The motor can be electrically coupled to an alternating current power source and can receive AC power from the power source. The flywheel can be coupled to a rotor external to the motor. The generator can be coupled to the flywheel and electrically coupled to a controller for supplying power to a load, such as an electric vehicle for charging one or more batteries of the vehicle.

Abstract: A bearing and flywheel system can include a first bearing portion having an opening of a first dimension there through and a central longitudinal axis, a second bearing portion having a second dimension, the second dimension being smaller than the first dimension, and a flywheel coupled to the second bearing portion. The bearing portions can include high-temperature superconductor(s) and/or magnets. The second bearing portion can be disposed at least partially within the opening through the first bearing portion. A gap can exist between an outer surface of the second bearing portion and an inner surface of the first bearing portion. The second bearing portion can be configured to rotate relative to the first bearing portion.

Abstract: A superconductor-magnet bearing system can include a first bearing portion and a second bearing portion. One of the first and second bearing portions can be at least partially composed of a high-temperature superconductor (HTS) and another can be at least partially composed of a magnet. The first bearing portion can be disposed at least partially within an opening of the second bearing portion with a gap between the first and second portions. A magnetic bearing portion can include a plurality of rings disposed next to one another. An HTS bearing portion can include a magnet. The bearing portions can be biased toward an alignment with one another. One bearing portion can rotate relative to another bearing portion.
