Abstract

Energi listrik merupakan salah satu kebutuhan manusia yang sangat penting dan vital yang tidak dapat dilepaskan dari keperluan sehari-hari. Baterai merupakan perangkat penyimpan energi listrik yang diperoleh dari reaksi kimia. Pada umumnya baterai yang dijumpai pada peralatan elektronik portabel yaitu baterai litium ion. Baterai jenis ini dapat diisi ulang agar dapat digunakan secara berkelanjutan. Proses isi ulang baterai pada penelitian ini menggunakan sistem charger constant current-constant voltage (cc-cv) yang berguna untuk mengendalikan tegangan dan arus pengisian agar tidak overcharge, dimana pada kondisi pengisian awal menggunakan cara kerja pengisian arus konstan. Komponen dari charger baterai ini terdiri dari dua tahapan yaitu constant current dengan menggunakan rangkaian buck converter, dan pada tahapan constant voltage dengan menggunakan rangkaian voltage regulator. Pada penelitian ini menggunakan sistem pengendalian berbasis algoritma fuzzy logic, sehingga dengan implementasi ini diharapkan charger baterai dapat bekerja dengan baik dalam mengontrol pengisian baterai. Perancangan dan pengujian sistem yang dilakukan meliputi buck converter, algoritma fuzzy logic, sensor tegangan, sensor arus, dan sistem charger secara keseluruhan. Hasil pengujian dan perancangan sistem tersebut, pengisian baterai ini menghasilkan tegangan sebesar 12,6V dan arus sebesar 2,5A. Pengisian akan mencapai penuh dan berhenti ketika arus yang mengalir menurun dan cut off pada aliran sebesar 100 mA.

Electrical energy is one of the most important and vital human needs that cannot be separated from daily needs. Batteries are electrical energy storage devices obtained from chemical reactions. In general, the batteries found in portable electronic equipment are lithium ion batteries. This type of battery is rechargeable for continuous use. The process of recharging the battery in this study uses a constant current-constant voltage (cc-cv) charging system which is useful for controlling the charging voltage and current so that it does not overcharge, where the initial charging condition uses a constant current charging method. The components of this battery charger consist of two stages, namely constant current using a buck converter circuit, and at constant voltage stages using a voltage regulator circuit. In this study using a control system based on fuzzy logic algorithms, so with this implementation it is expected that the battery charger can work well in controlling battery charging. The system design and testing carried out include buck converter, fuzzy logic algorithm, voltage sensor, current sensor, and charger system as a whole. The results of testing and designing the system, charging this battery produce a voltage of 12.6V and a current of 2.5A. Charging will be full and stop when the current flowing decreases and cut off at the flow of 100 mA.
