Abstract

As electric vehicle(EV) adoption increases, the need for efficient energy storage solutions, such as lithium-ion batteries(LIBs), also grows. However, higher battery capacities bring a higher risk of thermal runaway, impacting safety and performance. Effective thermal management is crucial for ensuring reliability and longevity. This study focuses on improving the performance of the water-cooling system for LIBs by modifying its geometry. Various designs, such as vortex generators(VG) and curved channels(CC), are tested to enhance heat transfer and cooling efficiency. These changes aim to achieve uniform heat distribution, reducing temperature differences between battery cells and preventing thermal runaway. Using computational fluid dynamics(CFD) simulations, the impact of different nozzle shapes and flow paths on thermal management is analyzed. The results show notable improvements in cooling performance and temperature uniformity that could enhance both safety and battery lifespan.
