Abstract
A traction battery assembly includes a battery array with a plurality of stacked cells and a serpentine heat exchanger. The heat exchanger defines passageways for coolant to flow therethrough. The heat exchanger is interleaved with the cells such that opposite sides of each of the cells are in contact with the heat exchanger.
Claims19
A traction battery comprising:
- a plurality of cells stacked in an array, wherein each of the cells have opposing major sides;
- and
- a serpentine heat exchanger including
- a body interleaved with the cells and including opposing panels disposed against the major sides, and including first and second edges each interconnecting the panels and extending along a length of the serpentine of the heat exchanger,
- an inlet manifold cooperating with the first edge to define an inlet chamber extending along the length of the serpentine, and
- an outlet manifold cooperating with the second edge to define an outlet chamber extending along the length of the serpentine, wherein the body defines at least one passageway extending between the inlet and outlet chambers to place the chambers in fluid communication such that coolant flows from the inlet manifold to the outlet manifold in a parallel cooling circuit.

A traction battery comprising:
- cells each having major sides;
- and
- a serpentine bladder interleaved with the cells and including
- a body portion having opposing panels in contact with the major sides and interconnected by a wall extending along a length of the serpentine bladder, and
- a manifold extending along an entire length of the wall and cooperating with the wall to define a chamber in fluid communication with a passageway defined between the panels.
2 more elements
A traction battery comprising:
- an array of cells each having major sides;
- a serpentine heat exchanger interleaved with the cells and including spaced panels defining passageways for coolant to flow therethrough and disposed against the major sides, wherein the panels cooperate to define a cutout extending through an entire thickness of the heat exchanger;
- and
- a spacer disposed in the cutout and directly engaging between an adjacent pair of the major sides.
