In general, air and liquid cooling systems can take away the heat generated by a lithium-ion battery by using a medium such as air or water to ensure that the lithium-ion battery's temperature is within a certain range.
In order to design a liquid cooling battery pack system that meets development requirements, a systematic design method is required. It includes below six steps. 1) Design input (determining the flow rate, battery heating power, and module layout in the battery pack, etc.);

Liquid-cooled battery packs have been identified as one of the most efficient and cost effective solutions to overcome these issues caused by both low temperatures and high temperatures.
The uniform temperature distribution within the battery pack is obtained. The thermal management of Lithium-Ion batteries has gained significant attention in the automobile industry. An efficient battery cooling system particularly active cooling techniques have opted as a promising solution in commercial electric vehicles.
The basic simplified model of the lithium-ion battery pack, which is equipped with a series of novel cooling systems and includes a single lithium-ion battery and different types of cooling structures, is shown in Fig. 1. The simplified single lithium-ion battery model has a length w of 120 mm, a width u of 66 mm, and a thickness v of 18 mm.
