Abstract
Komponen utama mobil listrik adalah sistem penyimpanannya. Baterai saat ini merupakan pilihan utama, namun memiliki kelemahan seperti kerapatan daya rendah, waktu pengisian lama, dan degradasi cepat. Untuk mengatasi kelemahan ini, sistem penyimpanan energi hibrida (HESS) yang menggabungkan baterai litium-ion (LIB) dan kapasitor litium-ion (LIC) dapat digunakan. Penelitian ini berfokus pada integrasi HESS untuk aplikasi mobil listrik, menentukan kapasitas sistem penyimpanan energi hibrida LIB-LIC, serta melakukan penentuan kapasitas dan pembagian daya (powersharing). Dua metode pembagian daya yang digunakan adalah metode berbasis aturan (rule based) dan metode filter lolos rendah (LPF). Metode berbasis aturan berhasil mengurangi arus maksimum baterai hingga 70%, sementara metode LPF mengurangi arus maksimum hingga 77% serta memberikan profil arus yang lebih halus tanpa lonjakan fluktuasi daya yang tinggi. Penelitian ini menunjukkan bahwa penambahan media LIC dapat memperpanjang umur LIB. Umur LIB pada HESS dengan metode berbasis aturan dan ukuran baterai yang telah disesuaikan (re-sizing) meningkat sebesar 17,64% dibandingkan sistem BESS. Sementara itu, umur LIB pada HESS dengan metode LPF dan ukuran baterai yang disesuaikan meningkat sebesar 36,15% dibandingkan BESS. Dari segi ekonomi, sistem penyimpanan energi hibrida LIB-LIC dengan metode LPF memiliki biaya awal tertinggi dibandingkan metode berbasis aturan dan BESS, tetapi efisiensi biaya jangka panjang menjadikannya pilihan paling ekonomis. Penelitian ini membuktikan bahwa HESS LIB-LIC dapat meningkatkan kinerja dan umur baterai dalam aplikasi mobil listrik, serta menawarkan solusi lebih efisien secara ekonomis selama masa siklus hidup sistem penyimpanan energi.

The main component of electric vehicles is the storage system. Currently, batteries are the primary choice, but they have drawbacks such as low power density, long charging times, and rapid degradation. To overcome these weaknesses, a hybrid energy storage system (HESS) that combines Lithium-Ion batteries (LIB) and Lithium-Ion Capacitor (LIC) can be used. This study focuses on the integration of HESS for electric vehicle applications, determining the capacity of the LIB-LIC hybrid energy storage system, and performing capacity determination and powersharing. Two power-sharing methods used are the rule-based method and the Low Pass Filter (LPF) method. The Rule Based method successfully reduced the maximum battery current by up to 70%, while the LPF method reduced the maximum battery current by up to 77% and provided a smoother current profile without high power fluctuation spikes. This study shows that adding LIC media can extend the lifespan of LIB. The lifespan of LIB in HESS with the Rule Based method and resized batteries increased by 17.64% compared to the BESS system. Meanwhile, the lifespan of LIB in HESS with the LPF method and resized batteries increased by 36.15% compared to BESS. Economically, the LIB-LIC hybrid energy storage system with the LPF method has the highest initial cost compared to the Rule Based method and BESS, but long-term cost efficiency makes it the most economical choice. This study proves that HESS LIB-LIC can improve battery performance and lifespan in electric vehicle applications and offer a more economically efficient solution over the energy storage system's lifecycle.
