Abstract: A traction battery assembly includes a conduit having an interior that carries a thermal management fluid. A thermal bridge extends into the conduit and spans across the interior from a first side of the conduit to an opposite, second side of the conduit. A traction battery thermal transfer method includes positioning a thermal bridge relative to a conduit such that the thermal bridge extends across an interior of the conduit from a first side of the conduit to an opposite, second side of the conduit, and moving a thermal management fluid through the conduit to exchange thermal energy with the thermal bridge.

Abstract: An electrified vehicle electrical system includes, among other things, a contactor enclosure, and contactor contacts housed within the contactor enclosure. A resistor is housed within the contactor enclosure or is housed within a relay enclosure outside the contactor enclosure.

Abstract: A battery assembly includes a plurality of cells stacked to form an array and a plurality of spacers each disposed between an adjacent pair of the cells. Each cell includes at least one terminal. Each of the spacers includes a retainer extending from an edge portion of the spacer. The retainers are configured to orient and engage a busbar for connecting the terminals of an adjacent pair of cells. The battery assembly may also include a busbar module. The busbar module may engage with the retainers to hold the busbar module to the array.

Abstract: An exemplary contactor assembly includes, among other things, a movable contact that transitions relative to a plurality of stationary contacts back and forth between a closed position and an open position. The movable contact contacts at least one of the stationary contacts with an initial contact surface and then a final contact surface when the movable contact is in the closed position. An exemplary contactor transitioning method includes, among other things, changing areas of contact between a movable contact and a plurality of stationary contacts when the movable contact is in a closed position with the plurality of stationary contacts.

Abstract: An exemplary contactor assembly includes, among other things, a moveable contact that moves back and forth between an electrically coupled position with a plurality of stationary contacts, and an electrically decoupled position with the stationary contacts. A support structure is configured to limit flexing of the moveable contact when in the electrically coupled position. An exemplary support method includes, among other things, transitioning a moveable contact from an electrically decoupled position to an electrically coupled position with a plurality of stationary contacts. The method further includes limiting a flexing movement of the moveable contact with a support structure.

Abstract: A vehicle is disclosed that has multiple coolant paths selected by control of a valve. A valve system is configured to direct coolant from an engine to a heat exchanger according to a difference between a temperature associated with the engine and a temperature associated with the heat exchanger. The valve system is also configured to direct coolant from the engine to an electric heater and to, in response to a heat demanded from the heat exchanger being greater than a heat capability of the electric heater, request the engine to run. A method is disclosed for controlling a valve to change from an isolation position in which the valve isolates coolant circulating through an electric heater and the valve from coolant circulating through an engine to a non-isolation position in which the valve directs coolant from the engine to the electric heater.
