A battery pack includes battery cells arranged in an array to form a battery module layer. Multiple layers are vertically stacked with thermal management devices, such as active heat exchangers in the form of battery cold plates, above and below each layer to form a multi-layer battery stack that may be held in compression. The battery cold plates include liquid heat exchange medium passageways, the characteristics of which influence the heating and cooling capabilities of the cold plates. The battery cold plates, including at least arrangement and features of the passageways across the battery cold plate, are optimized to achieve desirable pressure drop and temperature distribution across the cold plates, among other benefits.
