To solve this difficulty, various conditioning approaches, including air conditioning, liquid conditioning, and phase-change conditioning, have been proposed and researched. Liquid immersion cooling has gained traction as a potential solution for cooling lithium-ion batteries due to its superior characteristics.
While there are pros and cons to each cooling method, studies show that due to the size, weight, and power requirements of EVs, liquid cooling is a viable option for Li-ion batteries in EVs. Direct liquid cooling requires the battery cells to be submerged in the fluid, so it's important that the cooling liquid has low (or no) conductivity.
Instead, the liquid coolant can be circulated through metal pipes within the system, which requires the metal to have some sort of anticorrosion protection. Using COMSOL Multiphysics® and add-on Battery Design Module and Heat Transfer Module, engineers can model a liquid-cooled Li-ion battery pack to study and optimize the cooling process.
