1. A battery assembly comprising:
a plurality of prismatic battery cells each including a pair of opposing major sides and minor sides extending therebetween, the battery cells being arranged in an array with at least one of the majors sides facing another of the major sides, wherein the minor sides cooperate to define first and second longitudinal sides of the array; a plurality of spacers interleaved with the cells, each of the spacers including a frame disposed against at least two of the minor sides of a corresponding one of the cells and an elongate member extending between opposing portions of the frame and across one of the major sides of the corresponding cell to create an air gap between adjacent cells to allow air circulation between the cells; an inlet manifold disposed on the first longitudinal side and including an inlet arranged such that air flows into the manifold in a direction substantially parallel to the first longitudinal side; and a plate disposed within the manifold, extending along the first longitudinal side, and spaced apart from the first longitudinal side such that a distance between the plate and each of the minors sides is equal to define a plenum in fluid communication with the manifold and the air gaps, the plate having a proximal end near the inlet and a distal end, wherein the plate has openings that each define a pass-through area that allows the air to circulate through the plate and into the plenum, and wherein the openings are arranged on the plate such that the plate has a larger pass-through area near the proximal end than near the distal end. |
