1. A traction battery comprising:
- cells stacked in an array; and
thermal plates spaced apart to define a gap that receives the array, and including a plurality of tapered fins each extending out from only one of the thermal plates into the array and partially spanning the gap, and interleaved with the cells, wherein the cells are rotated at an oblique angle relative to an interior side of the thermal plates to seat against the fins.

Abstract
A traction battery assembly includes a battery array having a plurality of stacked cells and a pair of thermal plates arranged to sandwich the array therebetween. Each thermal plate includes a plurality of fins. Each fin extends out from one of the thermal plates into the array and is interleaved with the cells to cool or heat the cells. Also, disclosed is a vehicle including the traction battery assembly described above.

9. A traction battery assembly comprising:
-
a battery array including a plurality of stacked cells each having a pair of opposing major surfaces; and a thermal plate disposed adjacent to a minor surface of each of the cells and including a plurality of fins extending therefrom and terminating at a free end, wherein each of the fins is disposed against the major surfaces of two adjacent cells and only extends across a portion of the major surfaces such that the free end is disposed within a perimeter of the major surface, and wherein each of the fins further includes opposing contact surfaces that are configured to seat against the major surfaces and are angled inwardly such that the opposing contact surfaces are closer together at the free end than at a fixed end. - View Dependent Claims (10, 11, 12, 13, 14)
