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.

Abstract

This study proposes the use of Particle Swarm Optimization (PSO) algorithm to optimize the placement of Distributed Generation (DG) on the 20kV distribution system of Pujon feeder, which has 117 buses with the total distribution line length of 59.65 kilometers, with the aim to reduce power losses. In addition, PSO has also been used to determine the capacity of the DG. The JAYA algorithm is used as comparison. It has been proven that the proposed algorithm as well as the comparison algorithm succeeded in determining the optimum location and the capacity of DG to be installed

Abstract

Makalah ini membahas tentang penyeimbangan arus charging baterai lithium-ion pada BMS (Battery Management System) mobil listrik. Kondisi tidak seimbang pada saat proses pengisian baterai disebabkan karena salah satu baterai yang sudah terisi penuh sedangkan sebagiannya masih separuh atau bahkan hanya seperampat saja yang terisi. Kondisi ini dapat menyebabkan baterai cepat panas, serta melewati kondisi SOA (Safety of Area) sehingga menyebabkan kebakaran pada baterai. Pada penelitian ini, teknik cell-to-cell diusulkan untuk menyeimbangkan arus pengisian ke masing-masing sel baterai agar mendekati kondisi sama rata. Hasil simulasi menunjukan bahwa penggunaan teknik balancing cell-to-cell dapat menyeimbangkan sel baterai selama masa pengisian. Kata kunci: Penyeimbangan, Sel, Baterai, Lithium-ion, Cell-to-cell, BMS.
