Abstract: A cooling system includes a plurality of heat exchanger assemblies corresponding to a plurality of battery packs and a fluid conveyance assembly. Each heat exchanger assembly includes a first heat exchanger inlet-outlet and a second heat exchanger inlet-outlet configured to receive a heat transfer fluid or discharge the heat transfer fluid. The fluid conveyance assembly is coupled to the heat exchanger assemblies and configured to circulate the heat transfer fluid in parallel to the heat exchanger assemblies in a U-flow scheme with an inlet and an outlet of the heat transfer fluid arranged at the same location. The fluid conveyance assembly includes a plurality of flow restrictors configured to balance the heat transfer fluid flowing into the heat exchanger assemblies. The heat transfer fluid flows through the corresponding flow restrictor before flowing into the corresponding heat exchanger assembly of the battery pack.

Abstract: A battery module comprises: electrochemical cells arranged side by side in an array of multiple rows and columns, the electrochemical cells including terminals that comprise a first terminal at respective first ends of the electrochemical cells and at least portions of second terminals at the respective first ends; a housing that holds the electrochemical cells, the housing formed by a molding process with a polymer material; and a planar busbar extending along the terminals throughout the array, the planar busbar joined to the housing by an overmolding operation during the molding process without an adhesive between the planar busbar and the housing.

Abstract: A battery module for a modular high-voltage battery system comprises: electrochemical cells; a housing of an electrically insulating material, the housing enclosing the electrochemical cells; and a first connector at an outside surface of the housing, the first connector electrically connected to the electrochemical cells, the first connector comprising an insulating cover and a terminal accessible only through an opening in the insulating cover, the first connector configured for mating with a first electrical interconnect having a busbar to extend into the opening and contact the terminal.

Abstract: A safety interconnect for a modular high-voltage battery system comprises: a housing of an electrically insulating material, the housing having a cavity with an opening; and a busbar contained within the cavity, the busbar comprising a first terminal for connecting to a first external terminal of a first module of a modular high-voltage battery system, and a second terminal for connecting to a second external terminal of a second module of the modular high-voltage battery system adjacent the first module.

Abstract: A torque limiting clutch assembly is provided that is mounted between the motor housing and the ring gear of a planetary gear assembly. During normal operation, the clutch assembly prevents rotation of the ring gear relative to the motor housing. In the event of a severe loading condition, the clutch assembly slips, thereby preventing excessive torque from being applied to the drive train and potentially damaging one or more drive train components.
