Abstract

Kemajuan teknologi pada kendaraan listrik (EV) telah menciptakan tantangan dan peluang yang signifikan di industri otomotif. Salah satu tantangan dari penggunaan kendaraan listrik yaitu pada performa dari baterai yang perlu ditingkatkan. Penelitian ini difokuskan pada analisis kinerja tiga jenis baterai Lithium Iron Phosphate (LiFePO4) yang berbeda, yaitu 26650, 32700, dan 32140, dalam konteks kendaraan listrik. Penelitian ini ditujukan untuk mengevaluasi laju pelepasan arus dari baterai, perilaku tegangan jatuh baterai ketika pelepasan arus, dan efektivitasnya dalam menggerakkan motor listrik dalam kondisi pembebanan. Melalui pengaturan secara eksperimental, arus keluaran dari masing-masing jenis baterai akan diuji apakah sesuai dengan kebutuhan motor. Selain itu, analisis komparatif akan dilakukan untuk membandingkan kehilangan energi yang terkait dengan setiap jenis baterai selama pengosongan yang bertujuan untuk mengidentifikasi opsi baterai yang memiliki nilai tertinggi pada laju pengosongan dan rendahnya tegangan jatuh baterai. Hasil analisis dari penelitian performa tiga jenis baterai LiFePO4 (26650, 32140, dan 32700) pada uji akselerasi dari kecepatan 0 hingga 30 km/h. Baterai 26650 menunjukkan kestabilan performa yang baik dengan arus 8,26 A dan drop voltage 4,2–4,5 V. Baterai 32140 menghasilkan arus arus lebih tinggi sebesar 9,73 A dengan drop voltage lebih rendah (2,7–3,4 V) dan efisiensi energi tertinggi namun pada performanya mengalami fluktuasi. Sementara itu, baterai 32700 memiliki performa terendah, baik dari sisi arus, kestabilan, maupun efisiensi. Dari sisi kapasitas dan discharge rate, baterai 26650 (5 Ah) memiliki discharge rate tertinggi meskipun masih kalah stabil dari baterai 32140 (10 Ah), yang memiliki discharge rate rendah namun lebih stabil, meskipun arusnya kurang konsisten. Baterai 32700 (6 Ah) mencatat arus dan discharge rate terendah. Dalam hal efisiensi dan daya, baterai 32700 memang memiliki losses dan deviasi paling kecil, tetapi hal ini dikarenakan arus keluarannya rendah. Baterai 32140 mencatat daya tertinggi dan efisiensi terbaik (95,2%) meskipun dengan losses yang cukup besar, diikuti oleh baterai 26650 dengan efisiensi 93,9% dan performa yang stabil. Diharapkan hasil dari penelitian ini dapat memberikan wawasan yang berguna untuk memandu perkembangan masa depan dalam teknologi baterai pada kendaraan listrik (EV), serta meningkatkan kinerja, keberlanjutan, dan keandalan sumber energi untuk kendaraan listrik.

Advances in electric vehicle (EV) technology have created significant challenges and opportunities in the automotive industry. One of the challenges of using electric vehicles is improving battery performance. This study focuses on analyzing the performance of three different types of Lithium Iron Phosphate (LiFePO4) batteries—26650, 32700, and 32140—in the context of electric vehicles. The study aims to evaluate the current discharge rate of the batteries, their voltage drop behavior during discharge, and their effectiveness in powering electric motors under load conditions. Through experimental testing, the output current of each battery type will be tested to determine if it meets the motor's requirements. Additionally, a comparative analysis will be conducted to compare energy loss associated with each battery type during discharge, aiming to identify the battery option with the highest discharge rate and lowest voltage drop. The results of the performance analysis of three types of LiFePO4 batteries (26650, 32140, and 32700) in an acceleration test from 0 to 30 km/h. The 26650 batteries demonstrated good performance stability with a current of 8.26 A and a voltage drop of 4.2–4.5 V. The 32140 batteries produced a higher current of 9.73 A with a lower voltage drop (2.7–3.4 V) and the highest energy efficiency, but its performance fluctuated. Meanwhile, the 32700 batteries had the lowest performance in terms of current, stability, and efficiency. In terms of capacity and discharge rate, the 26650 batteries (5 Ah) have the highest discharge rate, though it is less stable than the 32140 battery (10 Ah), which has a lower discharge rate but is more stable, though its current is less consistent. The 32700 battery (6 Ah) has the lowest current and discharge rate. In terms of efficiency and power, the 32700 batteries have the smallest losses and deviations, but this is due to its low output current. The 32140 battery records the highest power and best efficiency (95.2%) despite significant losses, followed by the 26650 batteries with 93.9% efficiency and stable performance. It is hoped that the results of this study will provide valuable insights to guide future developments in battery technology for electric vehicles (EVs), as well as improve the performance, sustainability, and reliability of energy sources for electric vehicles.
