IOT Based Efficient Battery Monitoring System For E-Vehicles

DOWNLOAD ABSTRACT

AIM:

Design and development of IOT based Efficient Battery Monitoring System for E-Vehicles.

PURPOSE:

Battery monitoring system is very important for EV vehicle industry. Customized battery monitoring systems are available in battery but they do just balancing of cells and provide protection of charge and discharge of battery. We need smart BMS that will have additional features like data logging and IOT server interface.  We proposed IOT based battery monitoring system that will store voltage, current, temperature values in SD card and send this information to IOT server.

DESCRIPTION:

IOT module (ESP32) and Bluetooth (HC-05) interfaced to Arduino UART port. SD card connected to Arduino SPI port. DS1307 is a RTC module that will provide real time date and time information while data storing into SD card (memory card). Voltage and current sensors interfaced to Arduino analog pins.

WORKING:

Arduino continuously reads voltage, current and temperature values of battery and displaying on 16×2 LCD display. For every one minute time Arduino sends these values to IOT server through HTTP protocol with the help of ESP32. This information stored in SD card (memory card). This information is useful, when battery needs service or repair. In server this log information will display on graphs format to easy analysis. Using Bluetooth app user can set time if corrupted in RTC module.
