Özet

PCMs preferred in battery thermal management applications thanks to their latent and sensible heat capabilities. Also, it can be made even more effective by incorporating materials with high thermal conductivity. Carbon fiber can be an alternative because its thermal conductivity is higher than PCM. The aim of this study is to investigate the effect of carbon fiber meshes, which is more cost-effective than metals, on battery thermal performance. The mesh structure allows for equal cell spacing and enhances the module's mechanical properties. In this study, the thermal performance of the battery is experimentally investigated at different discharge rates by adding various layers of carbon fiber mesh to the PCM. In addition, the battery box is produced using copper mesh and carbon fiber fabric to transfer the heat generated in the module to the external environment more effectively. Thanks to carbon fiber, which has higher thermal conductivity than PCM, it can minimize both the temperature increase in the module and the temperature difference between the cells. The results show that adding PCM to the battery module leads to a reduction in peak temperature by 55.7% and 41.4% for 1C and 2C discharge rate, respectively. Additionally, by embedding the carbon fiber mesh inside the PCM, the thermal performance of the battery is improved by 13.6% and 7.6% in the 12 carbon fiber layer mesh and 6 carbon fiber layer mesh module respectively compared to the with only PCM battery module. Increasing the number of carbon fiber mesh layers is effective for the thermal performance of the battery module and minimizes the temperature difference between cells by using less weight PCM.
