Abstract
Electric vehicles are a key solution to reducing greenhouse gas emissions and dependence on fossil fuels. However, one of the main challenges in operating electric vehicles is overheating in lithium-ion batteries. Excessive temperature increases can lead to decreased efficiency, accelerated degradation of electrode materials, and the risk of thermal runaway, potentially endangering user safety. Therefore, an effective cooling system is needed to maintain battery temperatures within the optimal range to improve battery performance and lifespan. This study aims to analyze the effectiveness of various battery cooling systems in electric vehicles using ANSYS Fluent-based numerical simulations. Battery and cooling system geometry models were created in the ANSYS DesignModeler environment, followed by heat transfer and fluid flow modeling to evaluate temperature distribution and cooling efficiency. Analysis was conducted on several cooling methods, such as air cooling, liquid cooling, and phase change material (PCM)-based cooling. The simulation results show that the liquid cooling method with a flow velocity of 0.5 m/s has a higher thermal efficiency compared to air cooling, and the PCM with a difference in operating temperature reaches 5–15°C lower. From the results of this analysis, the liquid cooling method is recommended as an optimal solution in the thermal management of electric car batteries because it has a better heat dissipation capacity, maintains a stable battery temperature, and improves the safety and performance of the overall battery system. Keywords: Electric car, lithium-ion battery, cooling system, overheating, CFD, ANSYS Fluent. Mobil listrik menjadi solusi utama dalam mengurangi emisi gas rumah kaca dan ketergantungan terhadap bahan bakar fosil. Namun, salah satu tantangan utama dalam pengoperasian kendaraan listrik adalah masalah overheating pada baterai lithium-ion. Kenaikan suhu yang berlebihan dapat menyebabkan penurunan efisiensi, percepatan degradasi material elektroda, serta risiko thermal runaway, yang berpotensi membahayakan keselamatan pengguna. Oleh karena itu, diperlukan sistem pendinginan yang efektif untuk menjaga suhu baterai dalam rentang optimal guna meningkatkan performa dan umur pakai baterai. Penelitian ini bertujuan untuk menganalisis efektivitas berbagai metode sistem pendinginan baterai pada mobil listrik menggunakan simulasi numerik berbasis ANSYS Fluent. Model geometri baterai dan sistem pendingin dibuat dalam lingkungan ANSYS DesignModeler, kemudian dilakukan pemodelan perpindahan panas serta aliran fluida untuk mengevaluasi distribusi suhu dan efisiensi pendinginan. Analisis dilakukan terhadap beberapa metode pendinginan, seperti pendinginan udara, pendinginan cairan, dan pendinginan berbasis material perubahan fasa (PCM). Hasil simulasi menunjukkan bahwa metode pendinginan cairan dengan kecepatan aliran sebesar 0,5 m/s memiliki efisiensi termal yang lebih tinggi dibandingkan dengan pendinginan udara, dan PCM dengan perbedaan suhu operasi mencapai 5–15°C lebih rendah. Dari hasil analisis ini, metode pendinginan cairan direkomendasikan sebagai solusi optimal dalam manajemen termal baterai mobil listrik karena memiliki kapasitas pembuangan panas yang lebih baik, menjaga suhu baterai tetap stabil, serta meningkatkan keamanan dan kinerja sistem baterai secara keseluruhan. Kata Kunci: Mobil listrik, baterai lithium-ion, sistem pendinginan, overheating, CFD, ANSYS Fluent.
