EVCharger Project.

About

The purpose of this project is to create Smart EV-Charger that has the features as following.

1. Prepaid billing system.
2. Single-phase metering.
3. Real-time charging usage track on the Android app.
4. Charging and usage history.
5. Charger is accessible by scanning the QR code on the app.
6. Charger is accessible via RFID.
7. Dashboard to monitor the charging station's status.
