Abstract: A method includes receiving an indication of a charging current received at an on-board charging circuit of a vehicle from a source having a charging voltage. The on-board charging circuit includes a multi-phase traction motor, an inverter electrically coupled to the multi-phase traction motor and including an upper set of switching elements and a lower set of switching elements, and an energy storage device (ESD) electrically coupled to the inverter and having a storage voltage. The method includes determining whether the charging voltage is greater than or equal to the storage voltage. When the charging voltage is greater than or equal to the storage voltage, the method includes instructing at least one switching element in the upper set to operate in an on state and all of the switching elements in the lower set in an off state to cause fast charging of the ESD using the charging current.

Abstract: A rotor-wheeled motor assembly includes a wheel that includes a rim coaxial with an axis of rotation of the wheel and circumscribing an interior region of the wheel. The rim has a tire mounting surface and an interior radial surface on an opposite side than the tire mounting surface and opposing the interior region. The tire mounting surface is configured to mount the wheel to a vehicle hub assembly. An electric motor is disposed within the interior region and includes a rotor disposed on or embedded into the tire mounting surface. The rotor is configured to rotate in unison with the tire mounting surface about the axis of rotation along a plane perpendicular to the axis of rotation. A stator assembly includes a stator core and stator windings. The stator windings axially oppose the rotor to define an axial flux air gap separating the rotor and the stator windings.

Abstract: Techniques for strength training using an exercise system including an electric linear motor. The exercise system includes a stand, including the electric linear motor comprising a mover and a rotor, and a user interface. The exercise system further includes an exercise attachment coupled to the mover in the electric linear motor, and a controller configured to control force generated by the electric linear motor, where an amount of force required to move the exercise attachment changes based on the force generated by the electric linear motor, and configured to display information related to moving the exercise attachment.
