Intelligent Battery Management System Integrated with Solar PV for Residential Applications

The imperative to mitigate environmental harm is propelling the swift integration of renewable energy sources into the power grid. The intermittent generation of renewable energy can influence unpredictable electricity consumption, which can have security and system operation implications. To mitigate power generation fluctuations resulting from external factors such as wind speed, solar radiation, and climate variations, the implementation of a storage system becomes essential. The intelligence battery management system is crucial for contemporary battery- operated devices like electric automobiles, portable electronic devices, and renewable energy storage. It also enhances the battery’s lifespan, condition, and efficiency. Monitoring the battery’s state of charge is a critical aspect of battery management systems. This work focuses on monitoring the battery’s state of charge, temperature, and current for a solar panel system integrated with a battery for residential use. A microcontroller is utilized for control, while analog sensors are employed for detecting voltage and current parameters. Additionally, the research work emphasizes the design of an adaptive IoT communication protocol for efficient data transfer between the battery management system and Thing Speak, optimizing energy usage in IoT environments.
