A Novel Approach for Smart Battery Monitoring System in Electric Vehicles using Internet of Things

Abstract

Many fire accidents that occur recently are caused by electric vehicles like Ola, Okinawa, and Pure EV. The primary reason behind catching fire for EV scooters is a thermal runaway, and this occurs due to multiple reasons--melting of electrolyte, operational Temperatures of the battery, poor quality of the battery cells and battery packs, and lack of active cell assemblies. So, the proposed system intends to provide safety for EV users. For this, the battery’s temperature, battery’s size, and the voltage fluctuations of the battery are monitored by fixing the sensors to the battery of the electric vehicle along with other required IoT components. These values are monitored so that whenever these values cross their threshold limit the user will get a notification to mobile phone through mobile application as an alert message. Along with this, temperature readings, size indication, battery’s voltage percentage are also displayed on the display which is connected to the dashboard of the vehicle and also an alarm sound that alerts the user.
