Reva – IOT EV Charging Station Solution Developed Using Raspberry PI, Python, and Flutter

The project was centered on eliminating the hassle a person owning an electric vehicle has to go through in order to find a charging station. That’s the objective of building a smart charging station to charge all types of electric vehicles. 

● The user first registers himself and his EVs with the app. Subsequently, he can drive up to any of the charging stations, press a button on the app to start charging, and plug the charger into the car. 
● Using the mobile app users can select the location of nearby charging points and be able to connect with any charging station by scanning the QR code put over the charging station. 
● Whenever the user connects with a charging station the AWS IOT will publish the message through MQTT and the vehicle will start charging. 
● As soon as the user is done charging the vehicle s/he just needs to press a button over the app or unplug the cable, the application will automatically calculate and send the invoice the total electricity consumption and the bill for the energy consumed. 
● There are three applications governing the concept we aimed to achieve. These include the EV user’s end; the host’s end and the one maintaining the dashboard of the web application in order to protect the site from errors. 
● The EV user mobile app is an intuitive application designed for the user who has an electric vehicle and looking for a charging station. The user has to register in the app and insert the current location to view the nearby stations and can start charging the vehicle by inserting the OTP received by scanning the barcode present on the device. 
● The host app is one through which a user can buy the charging controller to host it in his shop/mall etc. and can onboard it to provide the charging services on a revenue-sharing basis with the controller provider. 
● The web application contains a responsive dashboard that acts as a super admin panel through which Zehntech as a charging controllers service provider can make sure that all the processes are running smoothly. It will also be used to redress the grievance and provide maintenance and support to the users and controller hosts.
