Anshori, Amar (2019) Teknik Fast Charging Baterai Lithium-Ion Menggunakan Logika Fuzzy. Magister thesis, Universitas Brawijaya.
Abstract
Meningkatnya penggunakan peralatan elektronik portable penggunaan baterai lithium-ion semakin banyak. Permasalahan yang terjadi dari meningkatnya penggunaan baterai menimbulkan masalah seperti kapasitas kurang besar, waktu pengisian lama, dan proteksi overcharging. Beberapa metode teknik pengisian baterai lithium-ion yang umum digunakan seperti metode Constan Voltage (CV), Constan Current (CC), CC-CV, dan reflex charging. Pada penelitian ini teknik fast charging baterai Lithium-ion menggunakan logika fuzzy untuk mengontrol temperatur dan tegangan pada saat melakukan pengisian baterai menggunakan metode pengisian Pulse Width Modulation (PWM), proses fuzifikasi yang digunakan adalah metode Mamdani dengan metode defuzzifikasi Center Of Gravity (COG). Diharapkan mampu mempercepat pengisian tanpa membuat temperatur baterai melebihi batas maksimal, serta mangatasi overcharging. Hasil pengisian menggunakan fast charger ini dengan menggunakan logika fuzzy terbukti dapat mempercepat pengisian dan melindungi terjadinya overcharging pada baterai.
English Abstract
The increasing use of portable electronic equipment uses more and more lithium-ion batteries. Issues that occur from increased use of the battery pose problems such as less capacity, long charging time, and overcharging protection. Some methods of lithium-ion battery charging techniques are commonly used such as Constan Voltage (CV), Constan Current (CC), CC-CV, and reflex charging methods. In this study the fast charging Lithium-ion battery technique uses fuzzy logic to control temperature and voltage during battery charging using the Pulse Width Modulation (PWM) Charging method, the fuzification process used Is Mamdani method with Center Of Gravity (COG) Defuzzification method. It is expected to accelerate the charging without making the battery temperature exceed the maximum limit, as well as the overcharging. The filling results using this fast charger using the fuzzy logic proved to accelerate charging and protect the occurrence of overcharging the battery.
