Liquid cooling is the most popular cooling technology. It uses a liquid coolant such as water, a refrigerant, or ethylene glycol to cool the battery. The liquid goes through tubes, cold plates, or other components that surround the cells and carry heat to another location, such as a radiator or a heat exchanger.
Mixtures of water and ethylene glycol are common coolants. Normally, the coolant flows along channels of pipes or cooling plates, carrying the rejected heat out of the battery pack [95, 96]. Based on the cooling channels’ position relative to the batteries, indirect cooling systems can be divided into bottom cooling and side cooling .
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.
Latest researches on battery liquid cooling system are summarized from three aspects. Properties and applications of different liquids are compared. Advantages and disadvantages of the different configurations are analyzed. Differences in the design scheme between direct and indirect cooling system is compared.
Almost all large battery packs now feature an active cooling system, both for increased safety and for increased battery lifetime. In an active cooling system, the heat is extracted using a coolant causing temperature gradients to build up within the cell and throughout the cooling system.
EV batteries can be cooled using air cooling or liquid cooling. Liquid cooling is the method of choice to meet modern cooling requirements. Let’s go over both methods to understand the difference. Air cooling uses air to cool the battery and exists in the passive and active forms.
