As electric vehicles (EVs) advance and battery capacities increase, new challenges arise that require solutions for effective cooling while maintaining energy efficiency. One such challenge is the pursuit of higher energy density, which generates more heat during operation and charging.
They pointed out that liquid cooling should be considered as the best choice for high charge and discharge rates, and it is the most suitable for large-scale battery applications in high-temperature environments. The comparison of advantages and disadvantages of different cooling systems is shown in Table 1. Figure 1.
Coolant compatibility with battery chemistry and materials can vary, potentially limiting use in certain batteries. These factors highlight the complexities and need for careful consideration when implementing liquid cooling systems .
Some new cooling technologies, such as microchannel cooling, have been introduced into battery systems to improve cooling efficiency. Intelligent cooling control: In order to better manage the battery temperature, intelligent cooling control systems are getting more and more attention.
Therefore, the current lithium-ion battery thermal management technology that combines multiple cooling systems is the main development direction. Suitable cooling methods can be selected and combined based on the advantages and disadvantages of different cooling technologies to meet the thermal management needs of different users. 1. Introduction
In the battery cooling system, early research used a combination of heat pipes and air cooling. The heat pipe coupled with air cooling can improve the insufficient heat dissipation under air cooling conditions [158, 159, 160, 161], which proves that it can achieve a good heat dissipation effect for the power battery.
Some scholars have adopted the coupling of flat heat pipes and air cooling and found that the effect of heat pipe coupling with forced air cooling is better , but there are cases where the cooling rate of the battery gradually decreases with the increase of air speed .
As electric vehicles (EVs) advance and battery capacities increase, new challenges arise that require solutions for effective cooling while maintaining energy efficiency. One such challenge is the pursuit of higher energy density, which generates more heat during operation and charging.

At present, the mainstream cooling is still air cooling, air cooling using air as a heat transfer medium. There are two common types of air cooling: 1. passive air cooling, which directly uses external air for heat transfer; 2. active air cooling, which can pre-heat or cool the external air before entering the battery system.
