Electric Vehicle Battery Parameters Monitoring System using IoT

The necessity for effective battery management to improve performance, safety, and battery life has been brought to light by the explosive expansion of electric vehicles (EVs). A solution based on the Internet of Things (IoT) is presented in this work for continuous tracking and analysis of important battery metrics, such as the outside temperature, electrical current, voltage, and the current state of charge (SOC). The system employs a network of sensors connected to a micro controller to gather data from the EV battery. This data is transmitted to the cloud using wireless communication protocols such as MQTT, enabling remote monitoring and predictive analytics. The proposed system aims to prevent potential battery hazards, such as thermal runaway, by providing early warning signals. Furthermore, the solution ensures optimal charging and discharging cycles, which enhances the battery lifespan and vehicle performance. A custom dashboard enables users and fleet operators to monitor battery health in real-time and receive alerts for any irregularities. The study discusses the system design, architecture, and the implementation of IoT in battery management systems. Experimental results demonstrate the reliability of the proposed system in improving battery safety and optimizing performance through predictive maintenance and data-driven decision-making. This work contributes to the advancement of smart electric vehicle infrastructure, facilitating the large-scale adoption of sustainable transportation.
