Abstract: In many of the Internet-Of-Things (IOT) applications, batteries are used to supply power to sensors and gateways. As Technology heads towards Industry 4.0, it is common to witness an increasing dependence on IOT technologies including the use of batteries. From electronics products such as mobile phones to Electric Vehicles (EVs), the use of rechargeable batteries for power supply can be remarkably highlighted. Lithium-ion batteries, for instance, are popularly used because of their high-energy density, versatility, low costs of manufacturing, durability and coulometric efficiency. However, the optimal Lithium-ion battery selection and the creation of electronic systems and algorithms for more efficient battery consumption are still open questions for scientists throughout the world. This project presents a solid method for battery-health monitoring which is based on different metrics “sensed”. A microcontroller which is used as an IOT gateway is utilized to send the battery health data to a cloud platform. The data are aggregated, visualized and analyzed so that meaningful real-time health monitoring, prediction of remaining discharge time as well as alerts can be made. Another objective of this project is to devise a smart charger system for the battery taking into consideration the energy-saving aspect as well as a renewable source of energy like solar energy. By utilizing ThingSpeak as the Cloud Platform, FireBeetleESP32 microcontroller as the IoT gateway and sensors like LC709203F Li-Po battery gauge, Smoke Sensor, Flame sensor and Temperature sensor, the IoT Battery monitoring system was designed. The cloud platform was able to provide real-time monitoring of important metrics for the battery including State-of-Charge(SoC), Battery Discharge Time, State-of-Health (SoH) and Charging status. The smart charger for the battery integrated with the prototype also showed positive results in terms of effective charging and sustainability.
