In a significant advancement for the energy sector, researchers at Politeknik Negeri Malang have developed an innovative IoT-based monitoring and controlling system designed to optimize battery energy consumption costs. This groundbreaking project, spearheaded by lead author Muhammad Fahmi Hakim, addresses a critical challenge faced by solar power plant entrepreneurs: ensuring batteries not only perform efficiently but also contribute to profitability.
The new system utilizes an ESP32 microcontroller in conjunction with an INA219 sensor, a single-channel 5 VDC optocoupler relay, and an OLED display. This combination allows for real-time monitoring of battery conditions, providing critical data such as consumed energy costs, current, voltage, power, consumed energy, and battery capacity. By harnessing the power of the Internet of Things (IoT), the system sends this information to the Blynk platform, enabling users to monitor their energy consumption remotely.
Hakim emphasized the system’s precision, stating, “Based on our test results, the average error in calculating energy costs is just 0.046%. This level of accuracy is vital for businesses looking to maximize their profits and ensure their battery systems are running optimally.” The research highlights the importance of real-time data in making informed decisions about energy usage and cost management.
The implications of this technology are vast. With the ability to control power flow to loads remotely via the Blynk platform, solar power plant operators can not only monitor their energy consumption but also adjust their systems according to real-time needs. This adaptability could lead to significant cost savings and improved operational efficiency, making solar energy a more attractive option for businesses.
As the world increasingly turns to renewable energy sources, innovations like this IoT-based system could play a pivotal role in shaping the future of energy management. By ensuring that battery systems are efficiently monitored and controlled, this research paves the way for enhanced profitability and sustainability in the solar power industry.
Published in ‘Jurnal Rekayasa Elektrika,’ or the Journal of Electrical Engineering, this research represents a crucial step forward in integrating advanced technology with renewable energy solutions, promising a brighter, more efficient future for energy consumption.
