Abstract
Pencemaran udara dari kendaraan berbasis mesin pembakaran dalam menjadi isu global yang mendesak karena dampaknya terhadap iklim dan kesehatan. Kendaraan listrik (EV) hadir sebagai solusi ramah lingkungan yang makin diminati, seiring kemajuan teknologi dan kesadaran masyarakat. Di Indonesia, penjualan EV terus meningkat meski belum mencapai target pemerintah, menunjukkan minat yang tumbuh terhadap transportasi hemat energi. Baterai sebagai sumber daya utama pada kendaraan listrik menghadirkan tantangan baru, terutama terkait dengan manajemen panas yang dihasilkan selama proses pengisian dan pengosongan daya. Salah satu jenis baterai yang banyak digunakan adalah baterai lithium ion. Karena itu, diperlukan sistem manajemen termal yang efektif untuk membantu memperpanjang usia pakai baterai. Pada penelitian ini menganalisis pengaruh penambahan material filler pada PCM komposit terhadap laju kenaikan temperatur. Metodologi melibatkan pengujian proses discharging baterai dengan beberapa variasi yaitu, PCM murni dan PCM komposit dengan tiga jenis filler yaitu Serbuk Grafit, Serbuk Alumunium dan Serbuk CuO. Lalu dibandingkan dengan natural koveksi. Hasil penelitian ini diharapkan memberikan kontribusi terhadap pengembangan teknologi baterai Lithium Ion yang lebih efektif dan aman.
Hasil penelitian menunjukkan bahwa penambahan PCM dan PCM komposit dapat menurunkan laju temperatur dan laju heat generation. Dari hasil yang didapat di C rate 3C 4C dan 5C, menunjukkan bahwa penambahan serbuk grafit memiliki hasil yang paling bagus di semua variasi C rate, lalu serbuk alumunium dan serbuk CuO. Dan untuk variasi PCM murni menunjukkan hasil yang paling buruk setelah natural konveksi. Hal ini sudah sesuai teori karena PCM murni memliki konduktivitas thermal yang lebih rendah dibanding lainnya.

Air pollution from internal combustion engine vehicles has become an urgent global issue due to its impact on climate and health. Electric vehicles (EVs) have emerged as an environmentally friendly solution that is increasingly popular, supported by technological advances and growing public awareness. In Indonesia, EV sales continue to rise even though they have not yet met government targets, indicating a growing interest in energy-efficient transportation. Batteries, as the main power source in electric vehicles, present new challenges, particularly related to managing the heat generated during charging and discharging processes. One widely used battery type is the lithium-ion battery. Therefore, an effective thermal management system is needed to help extend battery lifespan.
This study analyzes the effect of adding filler materials to composite PCM on the rate of temperature increase. The methodology involves testing the battery discharging process with several variations: pure PCM and composite PCM with three types of fillers—graphite powder, aluminum powder, and CuO powder. These are then compared with natural convection.
The results of this study show that the addition of PCM and composite PCM can reduce the temperature rise rate and heat generation rate. Results obtained at C-rates of 3C, 4C, and 5C indicate that the addition of graphite powder produced the best results across all C-rate variations, followed by aluminum powder and CuO powder. The pure PCM variation showed the worst results after natural convection. This is consistent with theory, as pure PCM has lower thermal conductivity than the other variations
