The State of the Art of Immersion Liquid Cooling Technology for Power Battery Thermal Management Applications

Blog Article

The battery thermal management system is a very important component of pure electric vehicles.With the promising application of liquid immersion technology in the field Letter Opener of electronic equipment, its application in battery thermal management systems has also received increasing attention.Power battery immersion liquid cooling technology is to directly immerse the battery in an insulating fluid and remove the heat from the battery through convection heat transfer or phase change heat transfer.From the perspective of power battery thermal management, the impact of temperature on battery performance and the advantages and limitations of using different battery thermal management systems are comparatively analyzed in this work, and the importance of an immersed battery thermal management system is explained.On this basis, the current key technical issues and related research progress of the liquid immersed battery thermal management system are reviewed in detail, including coolant selection, module design, life and safety Omega - 3 Algae research.

Finally, the power battery immersion liquid cooling products developed by some manufacturers for exploration or demonstration work are introduced.
