Özet
This study investigates the thermal management performance of five different battery cooling configurations (fan cooling, bottom cooling, bottom-top cooling, fan-bottom cooling, and fan-bottom-top cooling) applied to a lithium-ion battery module. The fan-based configuration was experimentally tested and used to validate the numerical model. A multi-scale multi-dimensional (MSMD) battery model was employed in ANSYS Fluent to predict the thermal response of other configurations under identical operating conditions. The experimental validation demonstrated good agreement with the numerical results, confirming the accuracy of the coupled MSMD and conjugate heat transfer approach. Comparative results show that the fan-bottom-top configuration provides the most uniform temperature distribution, while bottom cooling alone exhibits higher temperature gradients across the module. The highest cell temperature occurred at the fan cooling with 33.5 C, while the lowest occurred at hybrid configuration (fan-bottom-top) with 17.7 C. The findings provide insights into the optimization of hybrid cooling strategies for compact and energy-dense battery packs.
