1. A battery assembly for a vehicle comprising:
- a plurality of prismatic cells arranged to form a battery module;
a plurality of heat transfer elements between at least a majority of the cells with each heat transfer element presenting at least one thermal transfer edge extending beyond an edge of an adjacent cell; and
a first compression plate and a second compression plate positioned in generally parallel orientation to the cells and heat transfer elements and each disposed on an opposite side of the battery module relative to the other, the first and second compression plates connected with a plurality of fasteners that extend from the first compression plate to the second compression plate whereby the cells and heat transfer elements are compressed between the compression plates.

Abstract
A battery module of the present invention is adaptable to be utilized in various configurations including and not limited to an overlapping battery cell packaging configuration and a vertical stack battery cell packaging configuration used in an automotive vehicle. The battery module has a plurality of battery heatsink assemblies with the cells disposed therebetween. A plurality of rods extend through the each heatsink assemblies to secure the heatsink assemblies and the cell with one another to form the battery module.
