Abstract: A stator for an electric machine is fabricated by assembling a core and first and second winding assemblies. The first winding assembly (FWA) is fabricated by a 3D printing process and includes a plurality of U-shaped conductors (hairpins) having respective end-turns arranged in mutually axially-nested relationship to each other to form a ring, and further having two uprights disposed in one of the slots of the core. End-turns connect respective pairs of the uprights and are disposed adjacent to an end surface of the core, distal ends of the uprights projecting axially beyond an opposite end surface of the core. The second winding assembly (SWA) includes a plurality of bridges forming a second ring Opposite ends of each bridge define terminals that mate with ends of the uprights. The SWA further includes an electrically non-conductive casing in which at least one of the bridges is embedded.

Abstract: A vehicle power module assembly including first and second power modules is provided. The first power module may include a first lock feature extending from a lower portion of a first minor side at a first central axis. The second power module may include a second lock feature at an upper portion of a second minor side at a second central axis. The lock features may be sized for interlock with one another to secure the power modules to one another. The first lock feature may be a loop element defining a through-hole and the second lock feature may be a wedge. The through-hole may be sized for the wedge to extend therein and to interlock the first power module and the second power module to one another. The first lock feature may be a flexible hook element and the second lock feature may be a slot.

Abstract: A hands-free charging system includes a power source and a charging unit electrically connected to the power source. The charging unit includes an energy-storage device and a robotic coupler connectable to a charge port of a vehicle. The charging unit is configured to charge the vehicle with the power source, and the energy-storage device is configured to independently power the robotic coupler irrespective of an energization state of the power source. A controller is programmed to, in response to the power source becoming de-energized during a vehicle charging session, retract the robotic coupler from the charge port using power from the energy-storage device.

Abstract: An electric machine rotor that is configured to rotate about a first axis includes a plurality of plates and plurality of permanent magnets. The plurality of plates are stacked along the first axis. Each of the plates defines V-shaped pairs of cavities. Each V-shaped pair of cavities defines a pole arc angle. Each cavity has a permanent magnet pocket and a magnetic field guide chamber extending radially outward from the permanent magnet pocket relative to the first axis. Offset angles between the magnetic field guide chambers and the permanent magnet pockets vary within each plate. The plates are stacked such that the permanent magnet pockets between adjacent plates are axially aligned and such that the magnetic field guide chambers between adjacent plates are axially offset. Each permanent magnet extends through a set of permanent magnet pockets.

Abstract: A vehicle includes a pair of power converters. The vehicle includes a socket having an array of power terminals arranged to accept outlets of different power terminal configurations to interconnect the pair therewith. The vehicle includes a panel having an outlet engaged with the socket. The panel includes a controller configured to communicate an electrical rating of the outlet via the socket to define a switching scheme for the pair. The communication is responsive to detecting panel and socket engagement.

Abstract: A vehicle includes a power-electronics converter and an electrical outlet in electric communication with the power-electronics converter and configured to power external loads. The vehicle includes at least one electrical outlet including at least a first socket configured to power a first category of external loads and a second socket configured to power a second category of external loads. The vehicle is configured to only power one of the first and second loads at a time. This may be accomplished using physical features or electronically.

Abstract: A vehicle includes an electric machine having a number of pole pairs, N, a position sensor having a number of pole pairs, M, that generates output indicative of a rotational position of the electric machine, and one or more controllers. The one or more controllers generate a remapped rotational position according to a product of the rotational position and L/N, generate a scaled position according to a product of the remapped rotational position and N/M, and command the electric machine to produce a specified torque or speed based on the scaled position. M is not equal to and not a factor of N, and L is a minimum common multiplier of N and M.

Abstract: A vehicle includes an inverter configured to power an external device. The vehicle further includes a controller programmed to cause the inverter to output a voltage at a steady-state amplitude and a steady-state frequency and, responsive to detecting an inrush current event in progress that is caused by the external device, operate the inverter to reduce the voltage to prevent an overcurrent. The controller is programmed to identify the type of load connected and return the voltage to the steady-state amplitude and steady-state frequency based on the type of load.
