Abstract
Aplikasi Off-Board Charger banyak dikembangkan untuk peralatan pengisian baterai kendaraan listrik dengan waktu pengisian baterai dalam waktu yang lebih singkat. Off-Board Charger pada umumnya terdiri dari 2 konverter utama salah satunya yaitu Isolated DC/DC Converter. Konverter DC/DC konvensional seperi Buck Converter masih memiliki kekurangan seperti efisiensi yang rendah dan tidak memiliki kontrol yang sesuai dengan karakteristik baterai kendaraan listrik. Oleh karena itu, penelitian ini dilakukan untuk memperoleh desain Off-Board Charger dengan topologi Isolated DC/DC Converter yang memiliki kontrol Constant Current Constant Voltage (CCCV) untuk pengisian baterai kendaraan listrik. Half-Bridge Converter merupakan salah satu Isolated DC/DC converter yang mampu menghantarkan daya besar dan memiliki efisiensi yang tinggi. Hasil desain dan Implementasi yang telah dibuat menunjukkan bahwa efisiensi dari Half-Bridge Converter dapat mencapai 91% pada beban 1.5 kW dengan arus 14.4 A. Faktor peningkatan tegangan dipengaruhi oleh nilai arus keluaran. Saat arus mencapai 4 A maka peningkatan tegangan mengalami penurunan sehingga tidak sesuai dengan persamaan peningkatan tegangan. Pengujian kontrol CCCV menunjukkan mode CC arus 1 A memiliki ripple arus 7% sedangkan mode CC arus 1.5 A dan 2 A memiliki ripple arus 23 %. Respon kontrol CCCV telah sesuai dengan desain dan teori. Waktu untuk pengisian baterai tercepat adalah mode CC arus 2 A dengan waktu pengisian 17.83 menit.

Off-Board Charger applications are widely developed for electric vehicle battery charging equipment with a battery charging time in a shorter time. Off-Board Charger generally consists of 2 main converters, one of which is Isolated DC / DC Converter. Conventional DC / DC converters like Buck Converter still have drawbacks such as low efficiency and lack of control that matches the battery characteristics of electric vehicles. Therefore, this research was conducted to obtain the design of the Off-Board Charger with an Isolated DC / DC Converter topology that has Constant Current Constant Voltage (CCCV) control for charging electric vehicle batteries. Half-Bridge Converter is one of the Isolated DC / DC converters that can deliver large power and have high efficiency. The design and implementation results that have been made show that the efficiency of Half-Bridge Converter can reach 91% at a load of 1.5 kW with a current of 14.4 A. The voltage increase factor is affected by the output current value. When the current reaches 4 A, the voltage gain decreases so that it does not correspond to the voltage gain equation. Testing of CCCV control shows the CC mode of 1 A current has a 7% current ripple while the CC mode current of 1.5 A and 2 A has a current ripple of 23%. CCCV's control response is in accordance with the design and theory. The time for the fastest battery charging is CC mode current of 2 A with a charging time of 17.83 minutes.
