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.
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. As shown in the model, the liquid cooling system consists of five single lithium-ion batteries, four heat-conducting plates and two cooling plates.
For the cooling and heat dissipation of lithium battery pack, two cooling channel structures are feasible. In order to simplify the calculation, this paper selects 40 lithium batteries for design. The first kind of cooling and heat dissipation is a serpentine cooling channel.
Discussion: The proposed liquid cooling structure design can effectively manage and disperse the heat generated by the battery. This method provides a new idea for the optimization of the energy efficiency of the hybrid power system. This paper provides a new way for the efficient thermal management of the automotive power battery.
In addition, the type of coolant due to the difference in thermal conductivity also affects the cooling effect of the cooling and heat dissipation system of the lithium battery pack.
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.
