Abstract

A battery assembly includes: a plurality of cylindrical battery cells arranged in rows; a plurality of cooling barriers that are positioned between rows of the cylindrical battery cells and a cooling plate. The cooling barriers each include a conduit that extends between a first opening at a first end and a second opening at a second end, within the thickness of the cooling barrier. The cooling plate is on top of the cylindrical battery cells and comprises: a first port; a second port; a first manifold that provides a fluidic connection between the first port and the first openings in each of the cooling barriers; and a second manifold that provides a fluidic connection between the second port and the second openings in each of the cooling barriers. The first and / or the second manifold includes flow channels that extend along the cooling plate between its respective port and the associated openings in each of the cooling barriers.
