Abstract

Electrical energy consumption increase rapidly every year. The continuous energy supply must be secure due to high electrical energy demand. Battery bank is required to store the energy. Limitation of method for continuous monitoring the battery bank performances caused the process of maintaining the battery bank to be challenging. In order to continuously monitor the battery bank, this report presents a model of Smart Battery Monitoring System (SBMS). The SBMS is capable of continuous monitoring the battery bank at a distance and store the data periodically for further analysis. The SBMS works by measure the parameters of the battery which are voltage (V), current (A), ampere hours (Ah), power (W), watt hours (Wh) and State of Charge (SoC). The system consists of hardware (a microcontroller, sensors, a Bluetooth module, a SD card module, a memory card, a LCD display) and software development. The microcontroller board used is an Arduino UNO board (ATmega328P). Voltage is measured by voltage sensor module based on voltage divider concepts while current is measured by current sensor (ACS712-20A) and the readings transferred using Bluetooth communication system to display on a smartphone. The data also will be displayed on LCD. All the data will be stored in memory card for further analysis. The analysis shows that only 1% to 15% error between the Fluke meter and SBMS due to charging and discharging process of the battery. Based on the results, the voltage is inversely proportional to the current. The value of current increases with the drop of voltage value. SBMS provides a real time data of voltage, current, ampere hours, power, watt hours and State of Charge (SoC), then display data on the LCD and smartphone simultaneously.
