Abstract
Baterai lithium-ion (Li-ion) telah menjadi teknologi yang sangat diandalkan untuk mendukung berbagai perangkat, mulai dari elektronik portabel hingga kendaraan listrik. Meskipun popularitasnya, aspek keamanan, khususnya dalam konteks potensi overheating yang dapat menyebabkan kebakaran, tetap menjadi fokus utama. Penelitian ini bertujuan untuk menganalisis dampak dari faktor charging pada baterai Li-ion tipe 18650 terhadap variasi arus charging. Pengujian dilakukan dengan menggunakan baterai Li-ion tipe 18650 berkapasitas 2.000 mAh. Variasi arus charging yang diuji meliputi 2A, 4A, 6A, 8A, dan 10A dengan pemantauan pada kondisi State of charge (SoC) mulai dari 0% hingga 100%. Hasil penelitian menunjukkan bahwa variasi arus charging memiliki pengaruh yang signifikan pada kenaikan temperatur baterai Li-ion 18650 selama proses charging. Penelitian ini menunjukkan hasil uji yang mengindikasikan hubungan sebanding antara besarnya arus pengisian dengan peningkatan temperatur, sementara hubungan berbanding terbalik terlihat antara arus dan lama pengisian. Oleh karena itu, pemahaman mendalam terhadap faktor-faktor ini sangat penting dalam merancang pedoman keamanan khususnya pada kondisi pengisian baterai Li-ion untuk memastikan penggunaan yang aman dan efisien. Keywords: Baterai Li-Ion, Arus Charging, Kenaikan Temperatur ***** Lithium-ion (Li-ion) batteries have emerged as a highly reliable technology supporting various devices, from portable electronics to electric vehicles. Despite their widespread adoption, safety considerations, particularly regarding the potential for overheating leading to fires, remain a paramount focus. This study aims to examine the influence of charging factors on Li-ion type 18650 batteries concerning variations in charging current. Tests were conducted using a Li-ion type 18650 battery with a 2,000 mAh capacity. The evaluated charging current variations included 2A, 4A, 6A, 8A, and 10A, with meticulous monitoring under State of charge (SoC) conditions ranging from 0% to 100%. The research findings unequivocally suggest that variations in charging current exert a substantial impact on the temperature rise of Li-ion 18650 batteries during the charging process. This research elucidates test outcomes that signify a direct correlation between the magnitude of charging current and temperature escalation, concurrently demonstrating an inverse correlation between current and charging duration. Consequently, a comprehensive comprehension of these factors assumes paramount importance in formulating safety guidelines, particularly concerning the charging conditions of Li-ion batteries, thereby ensuring secure and efficient utilization. Keywords: Li-Ion Battery, Charging Current, Temperature Rise.
