Comparative analysis of optimum thermal management systems for battery modules comprising 32700 and 18650 LFP cells at equivalent power capacity level Energy, vol. 339. https://doi.org/10.1016/j.energy.2025.139084 Dönmez M., Tekin M., Karamangil M. İ. (2025) This study compares immersion-cooled battery modules built with 18650 and 32700 LFP cells at equivalent power capacity using multi-objective optimization. Results show both designs significantly reduce pressure drop (≈85–88%) with only minor increases in temperature, while maintaining effective thermal performance. The 18650 module offers better heat management, whereas the 32700 module achieves lower pressure losses and a more compact design. Overall, the work highlights how cell format and optimization strategy impact thermal behavior and flow efficiency in battery systems.

Using experimental data from multiple test profiles, the models are evaluated for their ability to capture both static and dynamic voltage behavior. Results show that the Dual Polarization model provides the highest accuracy across all conditions, particularly under dynamic loads. The findings emphasize the importance of model selection for improving BMS performance, energy efficiency, and battery lifetime.

Experimental analysis of the volumetric and thermal efficiency performance of a novel direct piezo-acting CVVT mechanism International Journal of Green Energy, 21(5), 948–958. https://doi.org/10.1080/15435075.2023.2226265 Sürmen A., Karamangil M. I., Avcı A., Dirim B., Işıklı F., Tekin M.,Türköz, N. (2024) This study experimentally evaluates a novel direct piezo-actuated continuously variable valve timing (CVVT) mechanism to optimize engine volumetric efficiency. Tests across multiple valve timings and engine speeds show improvements of 11.5% to 19.4% in volumetric efficiency compared to baseline operation, even with reduced valve lift. The results suggest a potential overall efficiency gain of 5–11.5%, depending on engine conditions. Despite practical limitations, the approach demonstrates promising performance benefits for advanced engine control systems.

Development and comparative analysis of a pure fuel cell configuration for a light commercial vehicle International Journal of Environmental Science and Technology, vol. 20, no. 6, pp. 6197-6208. https://doi.org/10.1007/s13762-022-04629-3 Tekin M., Karamangil M. İ. (2023) This study develops and compares a fuel cell powertrain configuration with a conventional diesel engine for a light commercial vehicle on a tank-to-wheel basis.
