How does the Audi e-Tron communicate with charging stations?

I am not sure how the e-Tron knows when and where to charge itself when using public charging stations. Is there some kind of communication between the car and the charging station?

The Audi e-Tron uses a technology called Combined Charging System (CCS), which allows for communication between the car and the charging station via a built-in charging port. This enables the car to determine the optimal charging rate and ensure compatibility with the charging station.

Yes, the car and charging station communicate through a protocol called ISO 15118. This allows for secure and seamless communication, as well as data exchange, between the e-Tron and the charging station.
