Abstract
Perkembangan sistem penyimpanan energi secara masif turut berkontribusi pada pengembangan aplikasi energi baru-terbarukan secara luas. Performa unik superkapasitor yang unggul dalam hal kerapatan energi dan kemampuan charge-discharge secara instan membutuhkan suatu pemodelan yang akurat melalui metode karakterisasi superkapasitor. Pemodelan superkapasitor menjadi rangkaian ekivalen R-C tiga cabang memiliki keunggulan tingkat akurasi yang tinggi dan prosesnya yang lebih sederhana. Dengan metode karakterisasi charge-discharge menggunakan arus konstan 8 A, maka parameter internal superkapasitor Maxwell 100 F dan 650 F dapat dimodelkan menjadi komponen penyusun rangkaian R-C tiga cabang yang terdiri atas resistansi dan kapasitansi serial yang terdiri dari tiga pasang dan dirangkai secara paralel. Serta dilakukan pengujian hybrid pulse power characterization (HPPC) sebagai validasi tingkat akurasi rangkaian pemodelan terhadap profil arus dinamis. Maka berdasarkan dari hasil Tugas Akhir ini dapat disimpulkan bahwa rangkaian R-C tiga cabang memiliki akurasi pemodelan yang tinggi terhadap hasil pengujian superkapasitor sesungguhnya. Selain itu, rangkaian R-C tiga cabang juga memiliki akurasi yang lebih tinggi daripada rangkaian R-C sederhana sebagai rangkaian pembanding baik pada metode pengujian charge-discharge maupun HPPC. Sehingga rangkaian R-C tiga cabang sebagai rangkaian pemodelan superkapasitor memiliki akurasi yang lebih tinggi daripada R-C sederhana.

The massive development of energy storage systems has contributed to the development of renewable energy applications widely. The unique performance of supercapacitors that are superior in terms of energy density and the ability of instant charge-discharge characteristic requires an accurate modeling through the supercapacitor characterization method. Supercapacitor modeling by R-C three-branch model equivalent circuit has the advantage of high accuracy and a simpler process. With the charge-discharge characterization method using a constant current of 8 A, the internal parameters of the Maxwell 100 F and 650 F supercapacitors can be modeled into a R-C three-branch circuit component that consist of three pairs serial resistance and capacitance. As well as hybrid pulse power characterization (HPPC) testing as a validation of the accuracy of the modeling circuit with dynamic current profiles. Based on the results of this Final Assignment it can be concluded that the R-C three-branch model has high modeling accuracy on the results of the actual supercapacitor testing. In addition, the R-C three-branches model also has a higher accuracy than the R-C standard model as a comparison circuit in both the charge-discharge and HPPC testing methods. So that the RC three-branch model as a series of supercapacitor modeling with higher accuracy than R-C standard model.
