Liquid cooling battery thermal management systems (LC-BTMS) are a very efficient approach for cooling batteries, especially in demanding applications like electric vehicles.
In terms of battery thermal management systems, PCMs are incorporated into battery packs to absorb and dissipate surplus heat produced during use . When there is a rise in battery temperature, PCM absorbs this generated heat and undergoes a phase transition from solid state to liquid through which the thermal (heat) energy is stored.
Herein, thermal management of lithium-ion battery has been performed via a liquid cooling theoretical model integrated with thermoelectric model of battery packs and single-phase heat transfer.
In summary, the performance of battery thermal management can be improved by adjusting the structure of indirect liquid cooling, but as the energy density of the battery continues to increase, this will create higher heat dissipation requirements for BTMS. 3.2. Direct Liquid Cooling
The aim is to optimize thermal management by utilizing a combination of LIC, and TEC to handle heat generation during battery operation, showcasing improved temperature control and performance in experimental tests.
With the increasing application of the lithium-ion battery, higher requirements are put forward for battery thermal management systems. Compared with other cooling methods, liquid cooling is an efficient cooling method, which can control the maximum temperature and maximum temperature difference of the battery within an acceptable range.
