Abstract: A traction battery assembly includes, among other things, a cover of a battery array, a holder attached to the cover, and a circuit board held by the holder in a position where the circuit board is spaced from the cover. The holder is configured to communicate thermal energy between the circuit board and the cover. A method of securing a circuit board of a traction battery pack includes, among other things, holding a circuit board with a holder, and attaching a holder that is holding the circuit board to a cover of a battery array. The circuit board held by the holder is held in a position where the circuit board is spaced from the cover.

Abstract: Fusible thermal interface materials are provided for traction battery packs. An exemplary fusible thermal interface material may be disposed between a grouping of battery cells and a heat exchanger plate for limiting the transfer of thermal energy associated with a battery thermal event from moving from cell-to-cell and/or compartment-to-compartment within the traction battery pack. The fusible thermal interface material may be configured to transition from a conductor to an insulator when a temperature exceeds a predefined temperature threshold.

Abstract: A traction battery assembly according to an exemplary aspect of the present disclosure includes, among other things, a thermal exchange plate having a plurality of coolant channels distributed within the thermal exchange plate according to a first pattern, and a thermal interface material disposed on a surface of the thermal exchange plate according to a second pattern. The first pattern mimics the second pattern.

Abstract: An exemplary battery assembly includes, among other things, an enclosure defining an interior, and a frame disposed within a wall of the enclosure. The frame includes at least one retention feature configured to hold a service panel in a position where the service panel covers an opening to the interior. An exemplary method includes, among other things, transitioning a service panel to an engaged position with at least one retention feature to secure the service panel in a position where the service panel covers an opening in an enclosure. The at least one retention feature is provided by a frame disposed within a wall of the enclosure.

Abstract: A battery array frame according to an exemplary aspect of the present disclosure includes, among other things, a frame body, and a thermal fin including a body embedded in the frame body and a leg that extends outside of the frame body. The thermal fin is flexible between a first position in which the leg is spaced farther from a surface of the frame body and a second position in which the leg is spaced closer to the surface of the frame body.
