This article primarily explores the application of immersive cooling technology in electric vehicle battery systems. As the demand for electric vehicles continues to rise due to high power output and fast charging requirements, the heat generation of batteries also increases. However, the adverse effects of high temperatures on battery performance and lifespan have become a critical issue. Graphene immersion cooling technology can provide more stable temperature control, prolong the lifespan of batteries, and enhance vehicle performance and safety. With the increasing demand for electric vehicles, immersive cooling technology is expected to be widely applied in the future.
