Abstract

Baterai Lithium-ion (Li-ion) adalah penyimpan energi yang unggul karena kestabilannya yang tinggi, tidak mengalami efek memori, memiliki tingkat self-discharge rendah, dan kepadatan energi yang tinggi. Selama penggunaannya, baterai menghasilkan panas akibat rugi energi dalam konversi energi kimia ke listrik dan perpindahan elektron. Oleh karena itu, sistem pendingin sangat diperlukan untuk mengendalikan panas tersebut. Salah satu metode yang sedang diteliti adalah pendinginan pasif menggunakan heat pipe, yang memiliki keunggulan dalam mengangkut energi panas dalam jumlah besar dengan cepat tanpa memerlukan daya eksternal. Penelitian ini bertujuan menentukan parameter geometri sistem pendingin yang optimal untuk baterai Li-ion. Melalui simulasi menggunakan software Ansys Fluent, variasi geometri heat pipe, material, discharge rate, dan kecepatan fan dianalisis. Hasil menunjukkan bahwa heat pipe dengan jumlah 4 unit, ketebalan 4 mm, berbahan copper, kondisi baterai dengan C-rate 2C, serta menggunakan fan dengan kecepatan 6 m/s dapat menurunkan suhu maksimum baterai hingga 4.981 K dengan efektivitas pendingin sebesar 0.4788, sehingga tipe heat pipe ini dapat digunakan sebagai sistem pendingin pasif untuk baterai Li-ion.

Lithium-ion (Li-ion) batteries are superior energy storage devices due to their high stability, lack of memory effect, low self-discharge rate, and high energy density. During their usage, batteries generate heat due to energy losses in the conversion of chemical energy to electricity and electron transfer. Therefore, a cooling system is essential to manage this heat. One method under investigation is passive cooling using heat pipes, which have the advantage of rapidly transporting large amounts of thermal energy without requiring external power. This study aims to determine the optimal geometry parameters for a cooling system for Li-ion batteries. Through simulations using Ansys Fluent software, variations in heat pipe geometry, material, discharge rate, and fan speed were analyzed. The results indicate that a configuration with 4 heat pipes, each 4 mm thick, made of copper, operating at a C-rate of 2C, and utilizing a fan speed of 6 m/s can reduce the maximum battery temperature by up to 4.981 K with a cooling effectiveness of 0.4788. Therefore, this type of heat pipe can be used as a passive cooling system for Li-ion batteries.
