The voltage and current are determined by negotiation between the car and charger. There were plenty of US Teslas imported into Norway in the early days. They have no trouble charging here. If necessary a simple conversion can be done.

Making my 2015 S70D that had a Type 2 connector work with CCS2 was a 300 USD conversion. I can't see any reason why converting from NACS to CCS2 would be any more difficult or expensive.
