Abstract
Mobil Formula Student elektrik membutuhkan sistem penyimpanan energi yang efisien, ringan, dan andal untuk menunjang performa optimal selama kompetisi. Penelitian ini bertujuan untuk merancang dan mengoptimasi sistem Hybrid Energy Storage System (HESS) pada mobil Anargya Mark 4.0 dengan mengombinasikan baterai dan superkapasitor. Simulasi kebutuhan energi dan daya kendaraan dilakukan berdasarkan strategi waktu tempuh minimum dalam menyelesaikan kompetisi Formula SAE Japan, yang kemudian digunakan sebagai dasar penentuan konfigurasi dan kapasitas penyimpanan energi. Hipotesis utama dalam penelitian ini menyatakan bahwa penyimpanan energi dapat dilakukan sepenuhnya oleh baterai ataupun superkapasitor, namun masing-masing memiliki kelebihan dan keterbatasan. Sistem berbasis baterai cenderung berat, sementara sistem berbasis superkapasitor lebih ringan namun mahal dan membutuhkan volume lebih besar akibat densitas energi yang rendah. Oleh karena itu, diperlukan pendekatan optimasi untuk menentukan kombinasi paling efisien dan efektif dari kedua komponen tersebut. Proses optimasi dilakukan menggunakan algoritma genetika (Genetic Algorithm) dengan fungsi objektif berupa kombinasi berbobot antara total berat dan biaya sistem. Hasil optimasi menunjukkan bahwa konfigurasi terbaik terdiri dari 91 sel baterai seri × 4 paralel (total 364 sel) dan 122 sel superkapasitor, dengan kapasitas energi 5,56 kWh dan daya 80,11 kW. Sistem ini memiliki berat total 34,63 kg dan biaya USD 4.740, yang berada di bawah batas teknis yang ditetapkan. Jika dibandingkan dengan sistem berbasis baterai penuh (BESS), konfigurasi HESS mampu mengurangi berat hingga 9,39% dan biaya hingga 3,54%. Sementara itu, dibandingkan dengan sistem berbasis superkapasitor penuh (SESS), pengurangan berat mencapai 96,25% dan biaya hingga 96,79%. Validasi sistem menunjukkan bahwa semua batasan teknis dan ekonomis telah terpenuhi, membuktikan bahwa integrasi superkapasitor dalam sistem penyimpanan energi memberikan manfaat signifikan untuk kendaraan performa tinggi seperti mobil Formula Student elektrik.

Electric Formula Student vehicles require an energy storage system that is efficient, lightweight, and reliable to support optimal performance during competition. This study aims to design and optimize a Hybrid Energy Storage System (HESS) for the Anargya Mark 4.0 vehicle by combining batteries and supercapacitors. Vehicle energy and power requirements were simulated based on a minimum lap time strategy for completing the Formula SAE Japan competition, and the results were used to determine the optimal configuration and capacity of the energy storage components. The main hypothesis of this research states that energy storage can be fulfilled entirely by either batteries or supercapacitors, each having its own strengths and limitations. A battery-only system tends to be heavy, while a supercapacitor-only system is lighter but more expensive and requires greater volume due to its lower energy density. Therefore, an optimization approach is needed to determine the most efficient and effective combination of both components. The optimization process was carried out using a Genetic Algorithm, with a weighted objective function based on the total weight and cost of the system. The optimization results show that the best configuration consists of 91 battery cells in series with 4 cells in parallel (totaling 364 cells) and 122 supercapacitor cells, providing 5.56 kWh of energy and 80.11 kW of power. The total system weight is 34.63 kg and the cost is USD 4,740—both within the predefined limits. Compared to a full battery energy storage system (BESS), the proposed HESS reduces weight by 9.39% and cost by 3.54%. Compared to a full supercapacitor energy storage system (SESS), the reductions reach 96.25% in weight and 96.79% in cost. Validation confirms that all technical and economic constraints are met, demonstrating that integrating supercapacitors into the energy storage system offers significant advantages for high-performance electric vehicles like Formula Student racecars.
