Abstract

The Battery Management System (BMS) is important because more and more electronic devices and vehicles use batteries as a power source. Without BMS, battery charging can become unstable, resulting in overcharging and reducing battery life. Therefore, BMS is becoming increasingly important as part of the development of safer and more efficient technologies, resulting in more reliable and safer electronic devices and vehicles. The Coulomb Counting method is used to determine the state of charge of the battery at the beginning and end of charging. The coulomb counting method is very accurate for determining the state of charge because it calculates the incoming and outgoing electric charge from the read current value. The voltage from source to load uses a buck converter to step down the voltage from 27.3V source to 25.5V load voltage. The Coulomb Counting (CC) method is used to estimate the SOC of the battery being monitored. The CC method is accurate for estimating the SOC value during charging and discharging but cannot determine the initial SOC value. The results of the current test have an accuracy of 96.03% and the voltage test has an accuracy of 99.22%.

Abstract

 The uncontrolled and excessive consumption of electrical energy, especially in households, often leads to significant energy waste. This issue adversely affects both consumers and electricity providers such as PLN. To address this problem, a system titled "Centralized Monitoring and Control Based on Load Characteristics Using the Internet of Things (IoT)" was developed. This system is designed to monitor and control household electrical loads in real time. The system consists of a PZEM-004T sensor for measuring voltage, current, power, energy usage, frequency, and power factor. An Arduino microcontroller processes the sensor data, while an ESP32 module transmits the data to an online database. A relay module is used to control electrical devices remotely. The data is stored in a database and visualized through a web-based interface, which also enables users to download monitoring reports in PDF or Excel formats. Testing results showed that the system operates with high accuracy. When compared to a standard power analyzer, the measurement error for parameters such as voltage, current, frequency, and power factor remained low, with a maximum error of only 1.9%. It demonstrates the system’s potential for efficient energy monitoring and management in residential settings.

Abstract

Inverter adalah salah satu alat elektronika yang digunakan untuk mengubah tegangan DC (Dirrect Current) menjadi tegangan AC (Alternating Current). Inverter ini diaplikasikan pada pembangkit listrik tenaga floating hydro portable. Gelombang output dari suatu inverter dapat berupa gelombang sinus (sine wave), gelombang kotak (square wave), dan gelombang sinus modifikasi (modified sine wave). Inverter 1 fasa full bridge ini dirancang menggunakan teknik PWM berbasis mikrokontroler Arduino uno, optocoupler sebagai driver 4 MOSFET, transistor 9014 sebagai penguat tegangan inverter, serta rangkaian double boost converter sebagai penaik tegangan pengganti transformator. Inverter ini menggunakan metode mengubah tegangan dari double boost converter 311 Volt DC menjadi 220 Volt AC dengan sumber utama accumulator 12 VDC-35Ah. Tegangan output yang dihasilkan oleh double boost converter sebesar 316 Volt DC. Inverter ini mampu mengubah tegangan 316 Volt DC ke 288,1 Volt AC frekuensi 49,50 Hz dengan gelombang output berbentuk gelombang kotak
