Abstract

Dikembangkannya Hybrid Electrical Energy Storage System (HESS) dengan superkapasitor, menawarkan karakteristik power density yang besar dan cycle life lebih besar daripada baterai. Karakteristik tersebut dibutuhkan untuk konversi energi ketika proses pengereman pada kendaraan listrik berlangsung agar energi dapat dipanen dengan cepat dan dalam jumlah yang besar untuk meningkatkan range. Pada penelitian ini dikembangkan sistem regenerative braking dengan menggunakan kendali constant current yang menentukan besar duty cycle pada scooter listrik FITS dengan propulsi motor Brushlees Direct Current (BLDC). Sistem dikembangkan dengan merancang hardware Power Converter berbasis kendali constant current melalui proses simulasi dan pengujian. Model kendali constant current dikembangkan untuk dapat menjaga arus pengisian sesuai dengan besar arus target. Besar arus dapat dijaga dengan menentukan besar duty cycle dari converter berdasarkan hasil pembacaan Back Electromotive Force (BEMF) dan tegangan supercapacitor. Sistem telah mampu menjaga besar arus sesuai dengan setpoint ketika proses pengereman berlangsung. Hasil simulasi dan pengujian cukup identik, dimana berdasarkan perubahan besar energi, tegagan, dan State of Charge (SOC) dari superkapasitor, sistem regenerative braking dengan kendali constant current target arus 30A memiliki performansi yang lebih baik dibandingkan dengan target arus 20A, dimana dengan penggunaan setting arus 20A nilai energi, tegangan dan SOC superkapasitor berturut-turut adalah sebesar 150,39 Joule; 51,6 V; dan 76,7%. Sedangkan untuk penggunaan setting arus target 30A, nilai energi, tegangan dan SOC superkapasitor berturut-turut adalah sebesar 260,83 Joule; 52,6 V; dan 78%.

The development of a Hybrid Electrical Energy Storage System (HESS) using supercapacitor, offers larger power density and greater cycle life than batteries. These characteristics are needed for energy conversion when electric vehicle posses braking process to harvest energy quickly in large quantities to increase vehicle range. In this research, regenerative braking system was developed using constant current control which controlled the duty cycle of FITS electric scooter with Brushless Direct Current (BLDC) motor propulsion. The system was developed by designing Power Converter hardware based on constant current control through simulation and testing process. Constant current control model was developed to maintain the charging current based on targeted current in setpoint. The current can be maintained by determining the duty cycle of the converter based on the Back Electromotive Force (BEMF) values and supercapacitor voltage. The system has been able to maintain current level according to the setpoint during the braking process. The simulation and test results are quite identical. The system using targeted current of 30A has better performance compared to the system while using targeted current of 20A, with the energy, voltage, and State of Charge (SOC) changes of the supercapacitor, respectively are 150,9 Joule; 51,6 V; dan 76,7%. While using targeted current of 30A, the values of energy, voltage, and SOC changes of the supercapasitor are 262 Joule; 52,5 V; dan 78%.
