Abstract

Baterai Lithium-Ion (Li-ion) telah menjadi sumber energi yang menjanjikan untuk kendaraan listrik karena kepadatan energinya yang tinggi dan stabilitas yang baik. Namun, akumulasi panas selama penggunaan baterai dapat menyebabkan penurunan kinerja dan bahkan thermal runaway. Phase Change Material (PCM) merupakan salah satu solusi pasif cooling yang efektif untuk mengatasi masalah ini. Penelitian ini mengevaluasi pengaruh kombinasi Phase Change Material (PCM) berbasis parafin dengan material komposit, seperti Expanded Graphite (EG), Aluminum Nitride (AlN), dan Copper Foam (CF), dalam meningkatkan efektivitas pendinginan baterai Lithium Ion Phosphate (LiFePO4). Simulasi menggunakan software Ansys Student dilakukan untuk menganalisis variasi ketebalan PCM (6-12 mm) dan konsentrat material (3%-15%) terhadap penurunan suhu baterai. Penelitian ini menganalisis pengaruh jenis ketebalan dan konsentrasi material komposit pada PCM terhadap performa pendinginan baterai. Hasil simulasi menunjukkan bahwa penggunaan PCM secara signifikan menurunkan temperatur baterai. Variasi dengan Cooling Effectiveness tertinggi sebesar 67% dicapai oleh PCM Expanded Graphite dengan ketebalan 12 mm dan konsentrasi 15% dengan penurunan suhu maksimum sebesar 17 K dibandingkan dengan baterai tanpa PCM dikarenakan latent heat rendah dikombinasikan dengan thermal conductivity sehingga penelitian ini memberikan informasi pengaruh laten heat dan thermal conductivity material komposit terhadap sistem pendingin baterai yang belum dilakukan pada penelitian sebelumnya.

Lithium-ion (Li-ion) batteries have become a promising energy source for electric vehicles due to their high energy density and good stability. However, heat accumulation during battery use can lead to performance degradation and even thermal runaway. Phase Change Material (PCM) is one of the effective passive cooling solutions for overcoming this problem. This study evaluates the effect of combining paraffin-based Phase Change Material (PCM) with composite materials, such as Expanded Graphite (EG), Aluminum Nitride (AlN), and Copper Foam (CF), in improving the cooling effectiveness of Lithium Ion Phosphate (LiFePO4) batteries. Simulations using Ansys Student software were conducted to analyze the variation of PCM thickness (6-12 mm) and material concentrate (3%-15%) on battery temperature reduction. This study analyzes the effect of the type of thickness and concentration of composite materials in PCM on battery cooling performance. Simulation results show that the use of PCM significantly reduces battery temperature. The variation with the highest Cooling Effectiveness of 67% is achieved by PCM Expanded Graphite with a thickness of 12 mm and a concentration of 15% with a maximum temperature drop of 17 K compared to batteries without PCM due to low latent heat combined with thermal conductivity so that this research provides information on the effect of latent heat and thermal conductivity of composite materials on battery cooling systems that have not been done in previous studies.
