Abstract
Kesadaran masyarakat terhadap bahayanya efek rumah kaca menjadi salah satu faktor utama untuk mengembangkan kendaraan yang ramah lingkungan yang saat ini dikenal dengan Electric Vehicle (EV). EV menggunakan motor sebagai penggeraknya dan baterai sebagai sumber energinya. Pada umumnya EV menggunakan jenis baterai Li-Ion karena memiliki kepadatan energi yang tinggi, memiliki karakteristik self discharge yang rendah, dan tidak mempunyai efek memori.
Baterai Li-Ion merupakan alat penyimpan energi listrik yang bersifat sementara. Ketika dihubungkan dengan beban EV, maka terjadi discharge pada baterai. Seiring berjalannya waktu, discharge mengakibatkan energi listrik yang tersimpan dalam baterai akan habis. Oleh karena itu, diperlukan battery charger untuk mengisi ulang baterai Li-Ion.
Tugas Akhir ini akan membahas mengenai desain dan implementasi battery charger Li-Ion 500 watt untuk EV (sepeda motor listrik). Battery charger yang dibuat menggunakan topologi buck converter dengan metode Constant Current Constant Voltage (CCCV). Hasil implementasi battery charger Li-Ion pada Tugas akhir ini menunjukkan bahwa ketika mode CC dapat menaikkan level tegangan sebanding dengan bertambahnya waktu. Sedangkan ketika mode CV arus charging baterai turun secara eksponensial sebanding dengan bertambahnya waktu. Set arus mode CC yang semakin tinggi dapat mempercepat durasi charging baterai. Dengan akurasi sensor arus dan tegangan masing-masing 1.15 % dan 3.67 % menghasilkan effisiensi sebesar 85 %.

People realize that risk of greenhouse effect is the main factors to develop environmentally friendly vehicles which it is known as electric vehicle (EV). EV uses the motor as its driver and battery as its energy source. Generally, EV uses Li-Ion battery type because it has high energy density, low self discharge characteristics, and no memory effect.
Li-Ion battery is a tentative electrical energy storage device. When battery connected to EV load, battery will be through discharge. Over time, the discharge generated electrical energy which borne in the battery will run out. Therefore, battery charger is required to recharge the Li-Ion battery.
This final project mainly disscuss about the design and implemmentation of battery charger Li-Ion 500 watt for EV (electric motorcycle). Battery charger that is made using buck converter topology with Constant Current Constant Voltage (CCCV) method. Result of implementation battery charger Li-Ion in this final project showing that CC mode can increase voltage level so it can be equal with the increase of time. While when in CV mode the current of battery charging decrease exponentially proportionate with the increase of time. Higher set on CC mode make the duration of battery charging become more faster. With the current sensor an voltage sensor accuracy 1.15% and 3.67% resulting 85% for efficiency.
