Abstract

Penggunaan baterai sebagai penyimpanan energi pada kursi roda elektrik telah ada sejak awal perkembangan kursi roda elektrik. Namun, baterai memiliki kelemahan yaitu, tidak dapat melakukan charge dan discharge dengan cepat tanpa menaikkan suhu, sehingga dapat mengurangi kinerja baterai dan dalam jangka panjang berkontribusi pada degradasi baterai. Cepat atau lambat, jika peak load dan average load current hanya di-supply oleh baterai, maka akan menyebabkan penurunan kualitas baterai itu sendiri. Untuk mencegah hal itu, perlu adanya sumber daya sementara untuk short-bursts energy pada saat terjadi arus puncak tinggi. Hybrid Energy Storage System (HESS) pada kursi roda elektrik dengan menggabungkan baterai-superkapasitor merupakan solusi yang efektif karena mampu menyediakan Energy Storage System (ESS) dengan kepadatan energi dan daya yang tinggi. Superkapasitor digunakan sebagai sumber daya sementara karena memiliki kepadatan daya yang lebih tinggi dibanding baterai dan mampu melakukan charge-discharge dengan cepat. Penerapan HESS terbukti mampu mengurangi pembebanan pada baterai, baik pada pengujian tanpa beban maupun dengan beban, baik ketika terjadi high peak load current maupun saat average load current. Pada penggunaan jangka panjang, supply arus ke motor oleh HESS menunjukkan adanya kestabilan. Hasil pengujian menunjukkan bahwa penambahan superkapasitor mampu mengurangi kerja baterai sebesar 30% – 40%, dan pada akhirnya meningkatkan jarak penggunaan kursi roda elektrik

The use of batteries as an energy storage system in electric wheelchairs has been present since the early development of electric wheelchairs. However, batteries have a drawback in that they cannot quickly charge and discharge without raising the temperature, which can reduce battery performance and contribute to long-term battery degradation. Sooner or later, if the peak load and average load current are solely supplied by the battery, it will lead to a decline in the battery's overall quality. To prevent this, there is a need for a temporary power source to provide short bursts of energy during periods of high peak currents. The Hybrid Energy Storage System (HESS) in electric wheelchairs, which combines batteries and supercapacitors, is an effective solution as it provides a high-energy and high-power Energy Storage System (ESS). Supercapacitors are utilized as the temporary power source due to their higher power density than batteries and their ability to perform rapid charge-discharge cycles. The implementation of HESS has proven to reduce the load on the battery, both in no-load and loaded conditions, whether it's during high peak load currents or average load currents. In the long run, HESS’s supply of current to the motor demonstrates stability. The test results indicate that the addition of supercapacitors is capable of reducing battery workload by 30% – 40%, ultimately increasing the usage range of the electric wheelchair
