The application of RFID in electric vehicle chargers is mainly used for identification and authorization. RFID, which stands for "Radio Frequency identification", is a communication technology that can read and capture information in an object equipped with an RFID tag through radio signals.

In electric vehicle chargers, RFID can be used to identify the car, and only authorized cars can use the charger. This prevents unauthorized use while also tracking and recording usage for easy billing and management.
