This paper work presents an Internet of Things-based system developed to observe and manage lithium-ion battery behavior through real-time sensing and cloud communication. The system measures essential battery parameters, including voltage, current, temperature, state of charge, and gas emissions, using integrated sensors connected to a Wi-Fi–enabled microcontroller. Collected data is processed and sent to a cloud dashboard, where users can remotely view battery performance and receive automated notifications when values exceed safe operating limits. The monitoring unit incorporates charging control and temperature-driven activation of a cooling mechanism to prevent overcharge, overheating, and chemical instability. Experimental validation confirms that the system provides accurate parameter tracking, stable wireless communication, and timely alert generation. The results demonstrate that the approach enhances battery protection, improves operational reliability, and extends usable battery life through continuous, automated supervision. The proposed design offers a low-cost and scalable method for intelligent battery monitoring suitable for portable devices, renewable-energy storage, and other applications requiring dependable real-time oversight.
