Abstract: A power module, such as a power module of a traction powertrain of an electrified vehicle, includes a power module cell arranged in a stack that defines a coolant supply manifold and a coolant return manifold. The power module cell includes a power stage having a substrate. The substrate includes first microchannels configured to input coolant from the supply manifold and impeded from outputting coolant to the return manifold, second microchannels configured to output coolant to the return manifold and impeded from inputting coolant from the supply manifold, and third microchannels crisscrossing and connecting the first and second microchannels in fluid communication.

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: A stator includes a core and an over-molded midsection arranged to define a plurality of slots, and a plurality of conductors wound within the slots. Portions of the midsection immediately adjacent to the slots define a plurality of protrusions disposed on opposite long faces of at least some of the slots. The protrusions extend into the at least some of the slots and between some of the conductors to establish a gap between the some of the conductors and to direct coolant between the some of the conductors.

Abstract: This disclosure relates to thermal management for an electric machine, such as an electric motor, of an electrified vehicle. An example assembly includes a stator having a core and a jacket at least partially surrounding the core. The jacket radially encloses a slot and is configured to permit fluid to flow within the slot from a first face of the stator to a second face of the stator. The assembly further includes a first end cover covering the first face of the stator. The first end cover has an inlet port and is configured to direct fluid from the inlet into the slot. Further, the assembly includes a second end cover covering the second face of the stator and configured to direct fluid that exits the slot.

Abstract: A vehicle includes a traction battery and a converter. The converter includes a switch and first and second busbars electrically connected in parallel between the traction battery and the switch. The second busbar has an inductance less than the first busbar and includes a resistor having a resistance at least an order of magnitude greater than a resistance of the first busbar.
