Common Battery Cooling Methods
The two types of battery heating and cooling include multiple implementation methods. Common battery cooling methods are divided into four types: natural cooling, air cooling (active + passive), active liquid cooling (plate + independent circuit), and active direct cooling.
The four cooling methods have their own advantages and disadvantages in terms of cooling efficiency and heating efficiency, and their material costs and system operation complexity are also completely different.
- Natural cooling: There is no additional device for heat exchange, and the heat of the battery pack is completely balanced by the surrounding environment. Its biggest advantage is simple structure and low cost. Of course, the disadvantage is that the heat dissipation performance is weak.
- Active air cooling and passive air cooling: using air flow for heat exchange, low cost and simple system, but at the same time the system is poorly sealed, resulting in low heating efficiency and unable to effectively balance the temperature.
- The direct cooling scheme directly changes the phase near the battery, and has the best cooling effect, but it cannot be heated by the phase change material, and the requirements for system control are relatively high.
- The liquid cooling system has certain advantages in meeting functional requirements through two circuits of refrigeration and heat exchange, but at the same time has disadvantages such as high cost and complex system.
