Pouch-type wrap for battery cell

摘要

A battery assembly includes a cold plate and a plurality of battery cells arranged in an array. Each of the cells has a bottom in contact with the cold plate and is encased in a dielectric jacket. The dielectric jacket surrounds side portions and the bottom of the cell. The jacket has seams on the side portions of the cells but not on the bottom. The seamless bottom forms a continuous and uninterrupted panel over the bottom to provide a seamless interface between the bottom and cold plate. A method of installing the cell into the jacket is also disclosed.
