The project entitled “IoT-Based State of Charge (SOC) Estimation and Monitoring of Lithium-Ion Battery for Electric Vehicles” aims to develop an efficient battery monitoring and protection system for electric vehicles using an Arduino UNO microcontroller. Lithium-ion batteries are widely used in electric vehicles due to their high energy density and performance. However, improper charging, excessive current, and high temperature can affect battery safety and lifespan. To overcome these problems, the proposed system continuously monitors important battery parameters such as voltage, current, temperature, and State of Charge (SOC). The INA219 sensor is used to measure battery voltage and current, while a temperature sensor monitors battery temperature. The Arduino UNO processes the sensor data and controls the battery charging and DC motor load through relay modules. Based on the battery voltage, the microcontroller automatically turns ON or OFF the charging supply and controls the motor load to protect the battery from unsafe operating conditions. An ESP8266 Wi-Fi module is used to upload real-time battery parameters to the ThingSpeak cloud platform along with date and time for remote monitoring. The same battery information is also displayed on an LCD. This system helps improve battery safety, enables remote monitoring, prevents improper charging and discharging, and increases the reliability and performance of electric vehicle battery systems.
