Optimalisasi Pengisian Baterai Daya Cepat Berbasis Arus Konstan-Tegangan Konstan dengan Buck Converter

Abstract

In today's era of technological advancement, electronic devices can be utilized anytime and anywhere thanks to battery assistance, especially in the usage of conventional motorcycles. Fast charging of batteries involves a method of charging with high current levels combined with voltage optimization. This research aims to optimize the charging of the GS ASTRA MF GTZ-5S 12V 3.5Ah motorcycle battery using the fast charging method based on constant current-constant voltage with the XL4015 buck converter. The results of the study indicate that the CC-CV method efficiently charges the battery in 78 minutes, reaching a final voltage of 13.8 V and a final charging current of 0.45 A, utilizing a relay protection system. Visualization of data using Google Colab and Python provides flexibility in data analysis, strengthening the interpretation of research findings. This study contributes to the development of efficient and safe fast charging methods, minimizing battery charging time, and ensuring the quality and safety of recharging
