The document describes an IoT-based electric vehicle charging station system designed to provide better environmental and socioeconomic conditions. The system uses QR codes to authenticate users and check parameters like available balance and charging port/time selection from an Android app. It discusses three cases: 1) A user with a new EV receives free charging, 2) A user whose free charging period has ended must pay, and 3) A user with a non-compatible EV must also pay. The system authenticates users via their unique IDs and allows/starts charging accordingly. It aims to motivate EV adoption while allowing manufacturers to offer charging networks.
