Abstract: An energy system of a building includes a power storage device, and a controller that, during a period of time for which energy costs are lowest, charges a power storage device to a maximum state of charge, and during a period of time for which energy costs are not lowest and an immediate subsequent period of time is predicted to have higher energy costs, charges the power storage device to a target state of charge that is less than the maximum state of charge and that depends on predicted power demand during the subsequent period of time.

Abstract: A vehicle, electric machine, and method of manufacturing an electric machine include a stator having teeth extending from a yoke portion toward a rotor and defining slots between adjacent teeth with windings positioned within the slots, wherein the slots are coated with an electrically insulating material having an arcuate surface exiting the slots and extending at least partially over the teeth on at least one end face of the stator to form a winding guide for bending/positioning the windings. The winding guide may be formed by a molded epoxy that replaces insulating paper slot liners while providing a template for forming the hairpin bends of end windings.

Abstract: An electric machine includes a rotor and a stator. The rotor is configured to generate rotational motion. The stator is disposed radially about the rotor. The stator has a core and windings. The core defines a first array of orifices about an inner diameter of the core and a second array of orifices radially outward from the first array of orifices. The windings are disposed within the first array of orifices. A magnetic material is configured to advance into and retract from the second array of orifices to adjust a magnetic flux within an airgap defined between the rotor and the stator.

Abstract: A permanent magnet formed by additively manufacturing magnetic phases and buffer phases is disclosed. The buffer phase(s) may improve performance, enhance mechanical properties and allow the magnet to better tolerate stresses such that defects such as cracking do not occur or are less likely to occur. The buffer phase may be a magnetic or non-magnetic material.

Abstract: An electrified vehicle and associated inverter configured for powering two different types of external loads include first and second phase/line legs combined with a first neutral leg coupled to a vehicle chassis, and a second floating neutral leg that is not coupled to the vehicle chassis. The first/second phase legs and first neutral leg are coupled to a first receptacle configured to receive a corresponding plug to power a first load, such as a power tool or accessory. The first/second phase legs and the second neutral leg are coupled to a second receptacle configured to receive a corresponding plug to power a second load, such as a home or building having an earth grounding electrode. The inverter may include an isolation transformer between the loads and the traction battery, and/or may be configured to provide single phase, split-phase, or three-phase power for either or both of the neutral connections.

Abstract: An electric machine for an electrified vehicle includes a stator core configured to receive a plurality of windings. The stator core including a plurality of interchangeable stacked laminations arranged in sub-stacks. The sub-stacks having an outer diameter surface divided into circumferential quadrants, each quadrant having a cutout extending inwardly at a predetermined depth and radial position to define a serpentine cooling path on the outer surface of at least a portion of the sub-stacks. The sub-stacks are circumferentially rotated relative to each other such that two quadrants have a first cutout orientation, and the two other quadrants have a second cutout orientation, the first cutout orientation is different than the second cutout orientation and when rotated in sequence each cutout aligns to form the continuous serpentine cooling path in a quadrant of the stator core.
