Abstract
Described herein are battery modules comprising immersion-cooled prismatic battery cells and methods of fabricating thereof. A battery module comprises prismatic battery cells that are stacked along the primary module axis. The module also comprises top, bottom, and side covers and two end plates, collectively enclosing these battery cells. Each cover forms two fluid channels, both fluidically open to the prismatic battery cells. Furthermore, the module comprises bus bars that interconnect the cell terminals and protrude into the fluid channels formed by the top cover. One end plate comprises two fluid ports for connecting to a thermal management system. Each port is fluidically coupled to one fluid channel, formed by the top cover, and one fluid channel, formed by the bottom cover. The other end plate fluidically couples the two fluid channels, formed by the top cover, and, separately, the two fluid channels, formed by the bottom cover.
