Abstract

Kapal nelayan tradisional umumnya masih menggunakan generator berbahan bakar fosil sebagai sumber energi listrik utama yang berdampak pada biaya operasional tinggi dan emisi gas buang, sehingga penelitian ini bertujuan merancang dan mengevaluasi modul battery pack berbasis Lithium Iron Phosphate (LiFePO₄) untuk kapal nelayan 6 meter (<1,0 GT) sebagai alternatif penyimpanan energi yang lebih efisien dan ramah lingkungan. Battery pack dirancang dengan konfigurasi 1P16S (51,2 V, 120 Ah) dilengkapi BMS dan sistem proteksi, kemudian diuji pada kondisi charging dan discharging dengan laju 0,5C dan 1C dengan parameter tegangan, arus, daya, dan temperatur. Hasil pengujian menunjukkan bahwa pada charging 0,5C temperatur meningkat dari sekitar 25,4°C hingga 38,5°C dengan tegangan naik dari 41,02 V menjadi 58,39 V, sedangkan pada charging 1C suhu naik lebih cepat dari 26,1°C hingga sekitar 39,8°C dan pada beberapa titik uji beban tinggi dapat melampaui 40°C. Pada pengujian discharge, arus terukur pada 0,5C sebesar 60,19 A dengan suhu pada kisaran ±27–36°C, sedangkan pada 1C arus terukur sebesar 86,09 A dengan suhu pada kisaran ±30–40°C serta penurunan tegangan yang lebih cepat. Berdasarkan hasil tersebut ditetapkan batas suhu aman operasi maksimum battery pack sebesar 40°C, sehingga operasi pada 0,5C dinilai paling stabil.

Traditional fishing vessels generally still rely on fossil-fuel generators as their primary source of electrical power, resulting in high operational costs and exhaust emissions. Therefore, this study aims to design and evaluate a Lithium Iron Phosphate (LiFePO₄)-based battery pack module for a 6-meter fishing boat (<1.0 GT) as a more efficient and environmentally friendly energy storage alternative. The battery pack is designed using a 1P16S configuration (51.2 V, 120 Ah) equipped with a Battery Management System (BMS) and protection system, and is tested under charging and discharging conditions at 0.5C and 1C rates with observed parameters including voltage, current, power, and temperature. Experimental results show that during 0.5C charging, the temperature increases from approximately 25.4°C to 38.5°C with voltage rising from 41.02 V to 58.39 V, while during 1C charging the temperature rises faster from 26.1°C to about 39.8°C and at several high-load points can exceed 40°C. In the discharge tests, the measured current at 0.5C is about 60.19 A with temperature in the range of ±27–36°C, whereas at 1C the measured current is about 86.09 A with temperature in the range of ±30–40°C and a faster voltage drop. Based on these results, the maximum safe operating temperature of the battery pack is set at 40°C, indicating that operation at 0.5C is the most stable condition
