The heat exchanger is interleaved with the cells such that opposite sides of each of the cells are in contact with the heat exchanger.

Abstract: A battery assembly includes a plurality of battery cells arranged in an array. The array has first and second longitudinal sides and a plurality of spacers interleaved with the cells to create an air gap between adjacent cells to allow air circulation between the cells. An inlet manifold is disposed on the first longitudinal side and includes an inlet arranged such that air flows into the manifold in a direction substantially parallel to the first longitudinal side. A plate is disposed within the manifold and extends along the first longitudinal side. The plate has a proximal end near the inlet and a distal end. The plate has openings that each define a pass-through area that allows the air to circulate through the plate. The openings are arranged on the plate such that the plate has a larger pass-through area near the proximal end than near the distal end.

Abstract: An assembly includes a traction battery of an electrified vehicle, and a blend door moveable between a first position that permits a first flow of air to move toward the traction battery and a second position that permits a second flow of air to move toward the traction battery. The first flow includes more air that has moved through an engine compartment than the second flow.

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.

Abstract: A fluid cooled series/parallel battery pack is provided with a fluid flow system. A plurality of prismatic battery cells are arranged in parallel in two or more rows. Fluid flows in a series flow configuration from an upstream row of batteries to a downstream row of batteries. A bypass passageway provides additional fluid flow to an inner plenum located between the rows of batteries to reduce pressure drop and provide more uniform temperatures within the rows of battery cells.

Abstract: An exemplary method includes providing an alert in response to an analysis of an array that includes at least a first recorded value and a second recorded value, the first recorded value corresponding to an electrical parameter of a battery joint under a first set of operating conditions, the second recorded value corresponding to the electrical parameter of the battery joint under a second set of operating conditions.

Abstract: A traction battery assembly for a vehicle is provided. The traction battery assembly may include a battery cell array and a thermal plate configured to support the battery cell array. The thermal plate may define an inlet port, two outer channels each having a channel inlet in communication with the inlet port, at least three inner channels disposed between the outer channels, and an outlet port. The ports and channels may be arranged such that fluid traveling through any two adjacent channels flows in opposite directions and fluid, when exiting the thermal plate, empties from one or more of the inner channels into the outlet port without first entering the channel inlets.

Abstract: An exemplary assembly includes a blend structure moveable between a first position and a second position. The blend structure in the first position permits a first flow of air. The blend structure in the second position permits a second flow of air. The first flow includes more air that has moved through an engine compartment of an electrified vehicle than the second flow.
