Abstract

Baterai merupakan suatu komponen dalam sistem listrik yang memiliki kemampuan untuk menyimpan energi dalam bentuk reaksi kimia. Saat energi disimpan dan dilepaskan oleh baterai, sebagian energi dapat hilang dan mengubah menjadi panas. Kelebihan panas ini dapat mengganggu kinerja baterai dan mengurangi umur pakainya. Oleh karena itu, sistem manajemen termal baterai sangat penting untuk menjaga suhu baterai tetap dalam kisaran operasional yang aman. Salah satu media untuk menurunkan temperatur baterai adalah dengan menggunakan cairan dielektrik. Penelitian ini akan membahas kinerja pendinginan baterai Lithium Ion menggunakan metode pencelupan dengan mempertimbangkan perubahan ketinggian cairan dan perubahan sudut rotasi terhadap sumbu-x (rolling) dan sumbu-z (pitching). Modul baterai yang akan disimulasikan memiliki kapasitas 50 Ah, dan cairan dielektrik menggunakan Novec 7300. Pencelupan divariasikan dengan persentase celup 90%,50%, dan 30% dengan sudut kemiringan 15o dan 35o. Berdasarkan hasil simulasi semua variasi celup dan sudut mampu menjaga suhu operasional aman yang disarankan produsen baterai yaitu dibawah 55oC, dan gerak rotasional pada sumbu-x (Rolling) dan sumbu-z (Pitching) dapat mempengaruhi kinerja pendinginan baterai dimana cakupan area cairan pendingin yang terendam pada saat rolling memiliki keseragaman suhu antar komponen baterai yang sama ditiap komponennya, dibandingkan pada saat pitching yang tidak seragam cakupan komponen yang terendam antar komponen baterai.

Battery is a component of an electrical system, storing energy through chemical reactions. During the process of energy storage and release, a certain amount of energy is lost and converted into heat. This excess heat can negatively impact the battery's performance and lifespan. Therefore, a reliable battery thermal management system is crucial to maintain battery temperature within a safe operating range. One effective approach to lower the battery temperature is using dielectric fluids. This study aims to investigate the cooling effectiveness of Lithium-Ion batteries utilizing the immersion cooling method, considering variations in liquid immersion levels and rotation angles around the x-axis (rolling) and z-axis (pitching). The simulated battery module has a capacity of 50 Ah, with Novec 7300 serving as dielectric fluid. The immersion levels tested include 90%, 50%, and 30% with inclination angles of 15° and 35°. From simulation results, it found that all immersion and rotation angle variations effectively maintain battery temperature below the manufacturer's recommended safe limit of 55°C. Furthermore, the rotational motion along the x-axis (rolling) and z-axis (pitching) significantly affects battery cooling performance, with rolling demonstrating more uniform temperature distribution across the battery cells compared to pitching, where the submerged coolant coverage is less uniform between the battery cells.
