The immersed battery pack has battery modules placed side by side with gaps between them. Coolant injection ports in the gaps spray liquid into the gaps to fully surround and cool the battery cells.
A power battery pack is composed of 10 lithium-ion power battery cells, and the arrangement is shown in Fig. 2. The volume of the box is 180 mm × 140 mm × 247 mm, and there is a 5-mm gap between the battery and the battery. The geometric modeling of the whole battery cooling system was established by the SCDM software.

Optimal cooling efficiency is achieved with three cooling channel inlets, minimizing the temperature difference across the battery pack.
