BEV cooling system is a cooling device used in battery pack heat dissipation. So, what are the cooling technologies for battery packs on the market?

1. Liquid cooling battery technology

This cooling technology has the application advantages of high specific heat capacity coefficient and high heat transfer coefficient. It mainly uses liquid media to effectively reduce the temperature of the power battery. The cooling medium used in liquid cooling battery technology is mainly liquid phase substances. Substances such as ethylene glycol, water and refrigerants can be used as refrigerants to achieve the cooling effect. Liquid-cooled battery technology can be subdivided into direct cooling methods and indirect cooling methods according to different contact methods.

Direct cooling method means that the battery module is immersed in the insulating cooling liquid, and the purpose of cooling is achieved by achieving direct contact between the cooling liquid and the battery pack. The indirect cooling method is to set up cooling coils around the battery pack, with cooling liquid flowing in them, and using convection heat transfer and refrigeration methods to reduce the operating temperature of the battery pack.

2. Air-cooled battery technology

This cooling technology uses air as the cooling medium and relies on the principle of convection heat exchange to achieve the purpose of cooling the battery pack. Air-cooled battery technology itself has the application characteristics of low maintenance cost and low manufacturing cost, so it can be widely used in power battery protection devices. At the same time, the application process of air-cooled battery technology is also restricted by the specific heat capacity and thermal conductivity of air. Therefore, the battery pack cooling efficiency of air-cooled battery technology is not high.

3. Heat pipe cooling battery technology

This cooling technology mainly uses hollow tube equipment with good sealing for cooling. By filling the hollow tube equipment with phase change working fluid, and setting up evaporators and condensers at both ends of the tube, the cooling effect is achieved. The application principle of heat pipe cooling battery technology is to use the evaporator to absorb sufficient heat, vaporize the liquid in the capillary core of the hollow tube in a closed state, and generate a certain air pressure, allowing it to gradually flow toward the condenser. The gas will release heat when passing through the condenser. , the gas will re-solidify into a liquid and continue to absorb heat, and the cycle will be repeated to achieve the purpose of lowering the temperature of the battery pack.

4. Phase change material cooling battery technology

This cooling technology mainly uses the principle of phase change heat absorption to achieve the purpose of reducing the operating temperature of the battery pack. Phase change materials themselves have the technical characteristics of excellent thermal stability and low application cost. Heat pipe cooling battery technology does not need to rely on channel equipment or electrical equipment during specific applications. It can ensure the uniformity of the overall temperature of the battery pack and avoid hot spots in the battery pack. Therefore, it can ensure stable operation of the battery pack during the application process.
