Abstract
Nogogeni ITS Team merupakan salah satu tim riset mobil listrik yang berfokus pada kendaraan hemat energi. Optimalisasi energi dan pemulihan energi penting dilakukan dan salah satu metodenya dengan sistem pengereman regeneratif yang bekerja dengan memanfaatkan BEMF motor untuk mendapat energi pengisian, pengereman regeneratif memerlukan sistem kendali dari motor agar dapat digunakan untuk pengisian dimana pembuatan sistem kendali tersebut membutuhkan beberapa tahapan mulai dari observasi lapangan, desain hardware, assembly dan kemudian mengintregasikan hardware ke mobil. Kendaraan yang akan digunakan yaitu Nogogeni VIII EVO diobservasi di workshop Nogogeni ITS Team untuk memperoleh spesifikasi yang diperlukan guna perancangan sistem, desain akan dievaluasi menurut standart IPC-2221 sebelum proses fabrikasi hardware. Dilakukan pengujian pada motor tanpa beban untuk memastikan bahwa sistem pengereman regeneratif dapat bekerja, pengambilan data uji jalan dilakukan dengan mobil Nogogeni VIII EVO di Jalan Pondok Candra Indah, controller akan diberi arus setpoint lalu diassembly ke mobil, mobil dijalankan sampai kecepatan setpoint lalu throttle dilepas. Dari hasil pengujian pada motor, sistem bekerja dengan menghasilkan perlambatan dari 617 rpm menjadi 0 dalam waktu 1,6 detik, selain itu baterai mengalami penambahan daya sebesar 0,03896 KWh dan pada uji jalan yang telah dilakukan memperoleh hasil bervariatif tergantung setpoint arus dan kecepatan terakhir sebelum throttle di lepas, dengan setpoint arus 4A dan kecepatan terakhir 10km/jam mobil berhenti setelah jarak 11m dan memperoleh daya pengisian sebesar 0,257 KWh, pada setpoint arus 5A dan kecepatan akhir 20km/jam mobil berhenti pada jarak 15m dengan pengisian sebesar 0,448KWh

Nogogeni ITS Team is a research team focusing on energy-efficient electric vehicles. Energy optimization and recovery are essential, and one method is the regenerative braking system, which utilizes the BEMF (Back Electromotive Force) of the motor to gain recharging energy. Regenerative braking requires a motor control system to enable recharging, which involves several stages: field observation, hardware design, assembly, and integration of the hardware into the vehicle. The vehicle used, Nogogeni VIII EVO, was observed in the Nogogeni ITS Team workshop to obtain the necessary specifications for system design. The design will be evaluated according to IPC-2221 standards before the hardware fabrication process. No-load motor testing was conducted to ensure that the regenerative braking system works. Road test data collection was carried out with Nogogeni VIII EVO on Jalan Pondok Candra Indah. The controller was given a setpoint current and then assembled into the vehicle. The vehicle was driven to the setpoint speed, and then the throttle was released. From the motor testing results, the system worked by decelerating from 617 rpm to 0 in 1.6 seconds. Additionally, the battery experienced an energy increase of 0.03896 kWh. In the road tests, the results varied depending on the setpoint current and the final speed before releasing the throttle. With a setpoint current of 4A and a final speed of 10 km/h, the vehicle stopped after a distance of 11 meters and gained a recharging energy of 0.257 kWh. At a setpoint current of 5A and a final speed of 20 km/h, the vehicle stopped after a distance of 15 meters, gaining 0.448 kWh of recharging energy.
