Abstract
Electric vehicle is a means of transportation used by Indonesian people to meet their needs. Developments in electric vehicles are very rapid, starting with vehicle design, safety and comfort in driving, as well as fuel efficiency, so that they will reduce air pollution and be environmentally friendly. Electric vehicle will not be separated from lithium ion battery as energy storage. If an electric vehicle is continuously used for both discharge and charge, the battery will experience excessive heat, therefore one way to stabilize excessive heat is to use a wavy channel battery cooling system and nanofluid media. This research aims to analyze the effectiveness of nanofluids in stabilizing temperatures in battery systems. This research carried out temperature and time measurements when the battery was in discharge and charge conditions, and used variations in nanofluid flow rates of 0.3 LPM, 0.6 LPM, and 0.9 LPM. The research results showed that the battery temperature before cooling reached 46.5℃. The use of nanofluid when discharged at this flow rate can reduce battery temperature. Meanwhile, when charging, the battery temperature before cooling reaches 35.8℃. Using of nanofluid with flow rates of 0.3 LPM and 0.6 LPM was not able to reduce battery temperature and a flow rate of 0.9 LPM was able to reduce the temperature. The percentage difference in temperature without cooling and nanofluid media when discharged are consecutively 3.96%, 5.61%, and 5.92%, respectively. Meanwhile, the temperature difference when charging is only 0.9 LPM, namely 1.87%.

| Additional Information: | Kendaraan listrik merupakan salah satu alat transportasi yang digunakan oleh masyarakat Indonesia untuk memenuhi kebutuhannya. Perkembangan pada kendaraan listrik sangat pesat, diawali dengan desain kendaraan, keamanan dan kenyamanan dalam berkendara, efisiensi bahan bakar, sehingga akan mengurangi polusi udara dan ramah lingkungan. Kendaraan listrik tidak akan lepas dari baterai lithium ion sebagai tempat penyimpanan energi. Jika kendaraan listrik terus digunakan baik discharge maupun charge maka baterai akan mengalami panas yang berlebihan. Salah satu cara untuk menstabilkan panas yang berlebihan yaitu menggunakan sistem pendingin baterai dengan menggunakan wavy channel dan media nanofuida. Penelitian ini bertujuan untuk menganalisis efektivitas nanofluida dalam menstabilkan temperatur pada sistem baterai. Penelitian ini dilakukan pengukuran temperatur dan waktu ketika baterai dalam kondisi discharge dan charge, serta menggunakan variasi laju aliran nanofluida 0,3 LPM, 0,6 LPM, dan 0,9 LPM. Hasil penelitian menunjukkan bahwa temperatur baterai sebelum didinginkan mencapai 46,5℃. Penggunaan nanofluida ketika discharge dengan laju aliran tersebut mampu menurunkan temperatur baterai. Sedangkan ketika charge temperatur baterai sebelum didinginkan mencapai 35,8℃. Penggunaan nanofluida dengan laju aliran 0,3 LPM dan 0,6 LPM belum mampu untuk menurunkan temperatur baterai dan laju aliran 0,9 LPM mampu menurunkan temperatur. Persentase selisih temperatur tanpa pendingin dan media nanofluida ketika discharge berturut – turut yaitu 3,96%, 5,61%, dan 5,92%. Sedangkan selisih temperatur ketika charge hanya 0,9 LPM yaitu 1,87%. | |||||||||
