8. Outlook Within the scope of this review, the concept of air cooled battery thermal management systems for electric vehicles have been presented. Classification criteria of all other BTMS methods have been briefly highlighted; while benefits and drawbacks of air cooled BTMS in comparison with other EV cooling strategy have been discussed.
In air convection cooling, the low thermal conductivity and low specific heat capacity of air prevent it from lowering the maximum temperature and maintaining a uniform temperature in the battery pack when there is a lot of heat . However, battery performance is closely related to temperature .
Since the batteries in the battery pack will generate a lot of heat during operation, the performance of the battery pack will be severely affected. As a result, new energy vehicles are increasingly being developed with a focus on enhancing the rapid and uniform heat dissipation of the battery pack during charging and discharging.
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.
Combining other cooling methods with air cooling, including PCM structures, liquid cooling, HVAC systems, heat pipes etc., an air-cooling system with these advanced enhancements should provide adequate cooling for new energy vehicles' high-energy battery packs.
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.
Compared with traditional air cooling methods, liquid cooling systems have higher heat dissipation efficiency and lower flow resistance, and have become the preferred choice for mainstream new energy vehicle manufacturers such as Tesla, Ningde Times and General Motors. In the future, as battery energy density and charging/discharging speeds continue to increase, liquid cooling
Thermal management of lithium-ion battery packs is a key technical problem that restricts the development of new-energy vehicles. The shape of air-cooled Lithium-ion battery packs is vital for thermal management system without replacing batteries.
Combining other cooling methods with air cooling, including PCM structures, liquid cooling, HVAC systems, heat pipes etc., an air-cooling system with these advanced enhancements should provide adequate cooling
According to whether the electric vehicle needs to provide auxiliary energy, it can be divided into active and passive heat dissipation methods. It can also be divided into natural convection and forced convection according to the causes of air flow outside the battery pack. For the air-cooled cooling system, it can be combined with the design of the driving characteristics
