IOT based E-vehicle Battery Management System

INSPIRATION

The inspiration for our intelligent electric vehicle (EV) system stemmed from the growing need for sustainable transportation solutions. We observed the challenges faced by EV users, such as range anxiety, inefficient route planning, and reliance on traditional charging infrastructure. Our goal was to create a comprehensive system that not only addresses these issues but also enhances the overall user experience and promotes eco-friendly transportation.

LEARNING

Throughout this project, we learned the importance of integrating hardware and software components to create a seamless and user-friendly solution. We gained insights into battery management, solar energy utilization, and the intricacies of developing a responsive web interface. Additionally, we understood the value of user feedback and iterative development to continuously improve our system.

PROJECT DESCRIPTION

Our project involved both hardware and software development:

HARDWARE: We designed and built a prototype of a dual-battery system that autonomously switches to a charged battery when the active one reaches a preset threshold. This ensures uninterrupted operation. Additionally, we integrated solar panels onto the vehicle’s roof to charge the inactive battery, further extending the vehicle’s range and reducing reliance on traditional charging infrastructure.

SOFTWARE: The software has two sides: server and client.

SERVER SIDE : This is for the e-stations to update slot availability regularly. CLIENT SIDE : This is the user web page where we developed a web application using HTML, CSS, and PHP that is installed on the EV’s onboard display. This application provides real-time updates on battery status, alerts for low charge, and other relevant information. It also includes a GPS-based charging station locator and reservation platform, allowing users to efficiently plan their routes and minimize charging downtime. Users get to know the slot vacancy in the selected e-stations and can book slots at charging stations in advance, enhancing time efficiency and convenience. Challenges Faced One of the main challenges we faced was ensuring seamless integration between the hardware and software components. Achieving reliable battery switching and efficient solar charging required extensive testing and optimization. Additionally, developing a user-friendly web interface that provides real-time data and supports reservation functionalities was technically demanding. We also encountered challenges related to data accuracy and ensuring that the GPS-based locator provided up-to-date information about charging station availability.

PROJECT IMPACT Our project has a significant impact on people, the planet, and the economy, aligning with various Sustainable Development Goals (SDGs). By integrating multiple features into an intelligent EV system, we enhance user experience and promote eco-friendly transportation. Real-time battery updates and efficient route planning via a GPS-based charging station locator reduce charging downtime, benefiting user convenience and cutting carbon emissions. The integration of a dual-battery system with solar charging extends the vehicle's range and decreases reliance on traditional infrastructure, contributing to environmental preservation. Economically, our solution drives innovation and job creation in renewable energy and EV sectors. Additionally, enabling slot booking prior to travel enhances time efficiency, optimizing route planning and fostering sustainable urban mobility.
