A battery chassis for immersion cooling includes one or more groups of battery cells, an inlet, a condenser, and one or more fluid connectors disposed on the top of the chassis. For example, an inlet is disposed on a bottom of the chassis to receive two-phase cooling fluid from an immersion container, and the two-phase cooling fluid is to extract heat from the one or more battery cells and to transform from a liquid form into a vapor. A condenser is disposed on a top of the chassis to condense the vapor contained within the chassis of the two-phase fluid back into the liquid form. One or more fluid connectors disposed on the top of the chassis to connect the condenser with external cooling fluid via a liquid line, and the battery chassis is to be at least partially submerged in the two-phase cooling fluid of the immersion container.
