## Abstract

A vehicle battery assembly having a battery stack that includes a plurality of modules. The plurality of modules fastened by vertical and horizontal bolts. The battery stack includes cooling plates that is configured to be flexible and non-rigid placed between the modules. The cooling plates have improved isolation of structural stresses from the battery assembly.
