Abstract

Described herein are swappable battery modules comprising immersion-thermally controlled prismatic battery cells and methods of operating thereof. A module comprises a tubular enclosure attached (e.g., glued) to different surfaces of the cells and forming two fluid channels with one side of the cells and two additional fluid channels with the opposite side. The module also comprises a first end plate, which is attached to the tubular enclosure and comprises two electrical terminals for connecting to an electric vehicle (EV) and/or external charger. The first end plate also comprises a first fluidic port (fluidically coupled with two fluid channels) and a second fluidic port (fluidically coupled to the remaining two fluid channels), both are configured to form fluidic coupling to the electric vehicle and/or the external charger. The module also comprises a second end plate that fluidically interconnects paid fluid channels from different cell sides.
