IoT Based Battery Parameter Measurement System

Abstract

This paper presents the design and implementation of an IoT-based battery parameter measurement system capable of real-time monitoring of voltage, current, temperature, and state-of-charge (SOC) for multiple battery cells. The system utilizes a PIC18F46K22 microcontroller for data acquisition, interfaced with voltage divider circuits and current sensors to measure key parameters. A Wi-Fi module enables wireless data transmission to a cloud platform, where real-time data can be accessed remotely. An intuitive web-based dashboard is used for data visualization, performance tracking, and alert generation in case of abnormal conditions such as overvoltage, under voltage, or overcurrent. The system supports EEPROM-based storage for set points and push-button-based calibration, ensuring accuracy, and flexibility in operation. This system is designed to address the limitations of traditional battery monitoring systems; this IoT-enabled solution enhances operational efficiency, enables preventive maintenance, and significantly reduces the risk of unexpected failures. The system is scalable, cost-effective, and suitable for a wide range of applications, including solar energy systems, electric vehicle battery packs, telecom towers, and industrial backup systems. By integrating embedded hardware with cloud-based IoT technologies, the proposed system offers a smart, connected, and efficient framework for continuous battery health monitoring and management.
