    Reduction the Thermal Effect of Battery by Using Liquid Cooling Techniques
    (American Institute of Physics, 2024) Abass, Hassnain F.
    This article explores various techniques to optimize the operation of lithium-ion batteries in electric vehicles (EVs). Lithium-ion batteries exhibit their highest performance within a temperature range of 16 to 25°C, while maintaining functionality within a broader range of 0 to 35°C. The article focuses on investigating different cooling methods, including liquid jackets, cold plates, microchannel cooling plates, serpentine channel cooling plates, and coolant immersion, to regulate the temperature of lithium-ion battery packs. The effectiveness of the thermal management system in maintaining the battery temperature within the specified operating range is thoroughly examined through experimental and simulation results. The findings reveal that these cooling techniques successfully control the temperature under various discharge loads. The recorded maximum temperature (Tmax) is 33.82°C, with a delta Tmax (ΔTmax) of 3.18°C at an ambient temperature of 26.5°C. Maintaining an appropriate temperature range is vital for optimizing the performance of lithium-ion batteries in EVs. The results provide valuable insights and pave the way for future research to enhance the thermal management system for lithium-ion battery packs in EVs. This article highlights the significance of maintaining the temperature range of lithium-ion batteries in EVs to ensure optimal performance. The explored techniques and methods present potential avenues for achieving this objective, and the findings serve as a reference for future studies aimed at improving the thermal management system for lithium-ion battery packs in EVs. © 2024 American Institute of Physics Inc..

    Thermal effect reduction in electrical vehicle battery using liquid cooling techniques
    (Altınbaş Üniversitesi / Lisansüstü Eğitim Enstitüsü, 2023) Abass, Hassnain F.; Alaiwi, Yaser
    The electrical vehicles were used new techniques to improve the boundary condition for work operation of lithium-ion battery which is consider main source for EV’s to storage energy and feeding the power to the electrical engine and appliance of it. The lithium-ion battery has operating temperature start from 0 to 35 ℃ degrees, but the ideal range start 16 to25 ℃ degrees. In the researcher focus on change in perspective of thermal management system that control to the cooling lithium-ion battery packs which is related and effecting on battery performance depending on heat transfer medium such as air, liquid or air-liquid or depending on the techniques of cooling such as liquid jacket, cold plate, micro channel, serpentine channel cooling plates, submerge battery packs in coolant. all these types discussed the cooling system and how maintain the batteries near to operating thermal range. To make this research go forward, we will discuss the techniques of reducing the different temperature by using cooling liquid medium and these techniques improved to reduction the thermal effect by uniform distribution techniques to achieve the best cooling distribution around the batteries. In present work, the our model results proved that the temperature under controlled at many different discharge load (1C,0.6C,0.667C,0.7C,0.88C) C-rates Tmax was controlled at 33.82 °C and ∆ Tmax =3.18 °C , ambient temperature (26.5°C).
