    Abstract: An electric machine may include a rotor defining a cavity containing a magnet, an outer periphery and a top bridge therebetween. The top bridge defines at least two segments. Each of the segments has a width that is minimum closest to a Q-axis, is maximum closest to a D-axis, and monotonically increases from the minimum to the maximum such that during operation a rate of change of rotor magnetomotive force associated with each segment differs.

    Abstract: An electric machine includes a unitary, single material substrate defining a rotor lamination including a first region having a predefined magnetic permeability. The rotor lamination includes an arc-shaped second region having a magnetic permeability less than the first region. The second region is oriented such that it impedes flux associated with magnets contained by the first region and perpendicular to quadrature flux field lines associated with the magnets.

    Abstract: An exemplary charging system includes, among other things, a first portable charger that electrically couples to an electrified vehicle to charge a traction battery of the electrified vehicle while a second portable charger is providing electrical energy to charge the traction battery. An exemplary charging method includes, among other things, electrically coupling both a first and a second portable charger to an electrified vehicle to charge a traction battery of the electrified vehicle using electrical energy from both the first and the second portable chargers.

    Abstract: Electronic devices are disclosed including hydrophobic or oleophobic coatings that control coolant flow therein or thereon. In at least one embodiment, a power inverter cold plate is provided including coolant inlet, a coolant outlet, a coolant flow spreading region, a coolant flow collection region, and a coolant heat-transfer region disposed therebetween; and one or more layers of a hydrophobic or oleophobic coating configured to control a flow of coolant in the cold plate. A method may include applying one or more layers of a hydrophobic or oleophobic coating to a power inverter cold plate to control a flow of coolant in the cold plate, the one or more layers being applied to one or more of a coolant flow spreading region, a coolant flow collection region, or a coolant heat-transfer region disposed therebetween. The layers may define coolant flow paths, eliminate recirculation zones, and/or prevent coolant leak paths.
