As I understand it, after a certain date, Teslas were built with the necessary hardware to use an upcoming CSS adapter (I have a 2021 per-refresh Model S and it has adapter support). This allows the adapter to be cheaper ($200-$250 according to rumors). For those cars that don’t have adapter support, rumor has it you’ll be able to upgrade the car so it will work with the Tesl adapter. Right now there are a few CSS adapters that work with Tesla, but they are $500-$600+. Someone correct me if I’m wrong, please.
