Artan küresel enerji talebi ve çevresel kaygılar, fosil yakıtlara dayalı ulaşım sistemlerinde sürdürülebilir alternatiflerin geliştirilmesini zorunlu kılmıştır. Bu doğrultuda elektrikli araçlar, yüksek verimlilikleri ve sıfır emisyon özellikleriyle ön plana çıkmaktadır. Elektrikli araçların temel bileşenlerinden biri olan lityum-iyon bataryalar, termal kararlılık açısından dikkatle izlenmeli; aşırı ısınmanın önüne geçilmelidir. Bu çalışmada, tasarlanan geometrideki sahip lityum-iyon batarya paketlerinin termal davranışı, boru destekli hava soğutmalı sistemle sayısal ve deneysel olarak incelenmiştir. Farklı hava akış hızlarında ve boru konfigürasyonlarında analiz edilerek soğutma performansları karşılaştırılmıştır. Sonuçlar, artan hava hızı ve boru sayısının sıcaklık dağılımını iyileştirdiğini, hücreler arası sıcaklık farkını azalttığını ve maksimum sıcaklık değerlerini düşürdüğünü göstermektedir. Çalışma, elektrikli araçlarda batarya güvenliğini artırmaya yönelik termal yönetim sistemlerinin optimizasyonu için önemli bulgular sunmaktadır.

The increasing global energy demand and environmental concerns have necessitated the development of sustainable alternatives to fossil fuel-based transportation systems. In this context, electric vehicles have gained prominence due to their high efficiency and zero-emission characteristics. Lithium-ion batteries, as one of the core components of electric vehicles, require careful monitoring for thermal stability to prevent overheating. In this study, the thermal behavior of lithium-ion battery packs with the designed geometry was investigated numerically and experimentally with a tube-supported air-cooled system. Cooling performances were compared by analyzing different air flow velocities and pipe configurations. The results demonstrate that increasing air velocity and the number of pipes improves temperature distribution, reduces temperature gradients between cells, and lowers maximum temperature values. This study provides significant insights for the optimization of thermal management systems aimed at enhancing battery safety in electric vehicles.
