In the rapidly evolving world of new energy vehicles (NEVs), battery thermal management is a critical factor that can make or break the performance and longevity of lithium-ion batteries. A recent study published in the *Journal of Power Sources* (Zhileng xuebao) sheds light on a promising technology that could revolutionize how we cool these powerhouses: immersed cooling.
Li Zhe, the lead author of the study, explains that immersed cooling involves submerging the battery directly in a coolant. This method offers several advantages over conventional cooling techniques like air cooling, indirect liquid cooling, and two-phase cooling. “The structure is simpler, cooling is faster, and temperature uniformity is significantly better,” Li notes. This could translate to improved battery performance and extended lifespan, which are crucial for both electric vehicle (EV) manufacturers and consumers.
The study delves into the nitty-gritty of immersed cooling technologies, including the screening of suitable immersion liquids, the design of cooling system structures, and thermal safety considerations. The findings are promising: immersed cooling can rapidly reduce battery temperature and enhance the temperature uniformity of the battery pack. This is a game-changer for the energy sector, as it could lead to more efficient and reliable EV batteries.
However, the technology is not without its challenges. Li points out that immersed cooling requires a high sealing performance of battery modules, and issues like leakage and corrosion need to be addressed. “These are not insurmountable hurdles,” Li assures, “but they do require further research and development.”
The commercial implications of this research are substantial. As the demand for NEVs continues to grow, so does the need for innovative battery cooling solutions. Immersed cooling technology could be a key player in this market, offering a more efficient and effective way to manage battery temperatures.
The study’s publication in the *Journal of Power Sources* underscores its significance in the field. As the energy sector continues to evolve, research like this will be instrumental in shaping the future of battery technology and, by extension, the future of transportation.
In the words of Li Zhe, “The potential of immersed cooling is vast, and we are only just beginning to scratch the surface.” As we look to a future powered by clean energy, this technology could be a crucial piece of the puzzle.
