Abstract

Listrik merupakan kebutuhan utama dalam kehidupan sehari-hari. Pemadaman listrik secara tiba-tiba dan berulang dapat merusak peralatan elektronik. Sistem Uninterruptible Power
Supply (UPS) digunakan sebagai cadangan energi saat listrik utama terganggu. UPS menggunakan baterai sebagai penyimpan energi, namun penggunaan baterai yang tidak terkontrol dapat menurunkan kualitasnya. Penelitian ini bertujuan merancang dan menguji sistem Kontrol Charging dan Monitoring Performa Baterai UPS berbasis IoT. Sistem ini menampilkan informasi tegangan, arus, temperatur, SoC, dan SoH baterai, serta mengontrol proses pengisian baterai UPS. Metode yang digunakan adalah kombinasi OCV dan Coulomb Counting untuk menghitung SoC baterai. Sistem ini menggunakan sensor INA219, sensor DS18B20, dan mikrokontroler Arduino Uno untuk memproses data dan mengontrol sistem. Data monitoring ditampilkan secara real-time pada aplikasi Android. Hasil pengujian menunjukkan bahwa sistem ini berfungsi dengan baik. Sensor INA219 1 memiliki akurasi arus 97,81% dan tegangan 97,50%. Sensor INA219 2 memiliki akurasi arus 97,05% dan tegangan 98,28%. Sensor DS18B20 memiliki akurasi 98,36%. Baterai diuji untuk proses discharge selama 23 jam 30 menit dan charging selama 2 jam 47 menit 43 detik, dengan SoH 95% yang menunjukkan kondisi baterai masih baik.

Electricity is essential in everyday life. Sudden and repeated power outages can damage electronic equipment. An Uninterruptible Power Supply (UPS) system is used as an energy backup when the main electricity is interrupted. UPS uses batteries as energy storage, but uncontrolled battery use can reduce their quality. This research aims to design and test an IoT-based UPS Battery Charging Control and Performance Monitoring system. The system displays battery voltage, current, temperature, SoC, SoH, and controls the UPS battery charging. The method used combines OCV and Coulomb Counting to calculate the battery SoC. The system uses INA219, DS18B20 sensors, and an Arduino Uno microcontroller to process data and control the system. Monitoring data is displayed in real-time on an Android application. Test results show the system works well. INA219 sensor 1 has an accuracy of 97.81% for current and 97.50% for voltage. INA219 sensor 2 has an accuracy of 97.05% for current and 98.28% for voltage. The DS18B20 sensor has an accuracy of 98.36%. The battery was tested with a discharge process for 23 hours and 30 minutes and charging for 2 hours and 47 minutes 43 seconds, with a SoH of 95%, indicating the battery is in good condition.
