Review on the thermal management of lithium ion batteries based on energy-efficient liquid cooling techniques
In the thermal management technology of lithium ion battery packs for electric vehicles,liquid cooling is recognized as the mainstream technique due to its high performance and efficiency.It can be further categorized into indirect liquid cooling and direct liquid cooling.This paper reviews studies on battery pack temperature control utilizing different liquid cooling methods based on bat-tery shape,such as liquid cooling plate(including designs of flow channels and layout),immersion liq-uid cooling,and composite liquid cooling combined with phase change materials.Temperature con-trol data under different liquid cooling methods are presented,compared,and analyzed.Typically,for prismatic or pouch batteries,liquid cooling plates can be flexibly arranged at the bottom of the cell module,between large surfaces of the batteries,or on the small sides of the batteries.Liquid cool-ing plates often feature structures such as serpentine channels,biomimetic channels,and fin-shaped structures.For cylindrical batteries,the channels in the liquid cooling plates are often designed in wavy,jacketed,or spiral.
