  • Patent number: 11557934
    Abstract: An electric machine includes a core with windings positioned on the core. The windings include in-slot portions, end turns, and leads. The in-slot portions are positioned in slots of the core. The end turns extend from the in-slot portions at ends of the core. The leads extend from the in-slot portions and axially past the end turns. A bus bar assembly is positioned radially inward from the end turns. The bus bar assembly includes an arc portion, a plurality of axial lead connectors, and a plurality of axial phase terminals. The arc portion is positioned axially within the end turns. The axial lead connectors extend axially past the end turns and are connected to the leads. The axial phase terminals also extend axially past the end turns.

  • Patent number: 11545867
    Abstract: An electric machine includes a stator assembly and a bus bar assembly. The stator assembly includes a core with windings positioned on the core. The windings include in-slot portions, end turns, and leads. The leads extend from the in-slot portions at one of the ends of the core with ends of the leads extending axially past the end turns. The leads include a first plurality of leads positioned on a first side of the stator opposite a second plurality of leads positioned on a second side of the stator. The bus bar is substantially circular in shape and positioned radially inward from the end turns. The bus bar assembly includes three bus bars, each bus bar connecting at least one of the first plurality of leads to at least one of the second plurality of leads.

  • Patent number: 10773720
    Abstract: Systems and methods for implementing a start-stop feature on a vehicle powered at least in party by an internal combustion engine are described. The method includes receiving, at an electronic control unit (“ECU”) of the vehicle, an indication that the vehicle is in line at a drive-thru. The method further includes determining, by the ECU, a number of start-stop events anticipated during the drive-thru. The method includes determining, by the ECU, an approximate stop time for each of the number of start-stop events. The method further includes determining, by the ECU, that a battery of the vehicle has enough remaining charge to power a plurality of vehicle components during implementation of the start-stop feature. The method includes implementing, by the ECU, the start-stop feature in which the internal combustion engine is turned off for at least a portion of the time when the vehicle is stopped.
