IoT based Lithium-Ion Battery Monitoring System in Electric Vehicle

A system to monitor and examine the parameters such as temperature, voltage, current, charge and discharge cycle of Lithium-ion battery is developed. Frequent monitoring and a way to manage the battery temperature is necessary to improve battery performance in electric vehicles. The performance characteristics of the batteries, being the vehicle’s primary power source determines the lifecycle, safety and mileage of an electric vehicle. The system consists of a microcontroller-based circuit, with solid state components for handling sensors, data communication module which is based on IOT protocol. The battery monitoring and management system is constructed with a liquid cooling system in which a coolant tube is inserted between battery cells to cool them when they are overheated. The system is installed in electric vehicles and by measuring above parameters it will help the users to optimally utilize battery and identify problems before any failure. Here the information of abnormality is sent to the user mobile phone through the IoT.
