So far the only car in the USA that supports the ISO 15118 standard “plug and charge” that I am aware of is the 2021+ Porsche Taycan Platform. Technically the same hardware -may- be present in the J1 Audi eTron GT but that is not clear yet. I’ve lurked both forums, and owned a ‘20 and ‘21 Taycan— the latter did work at EA for P’n’C but that was it. All other cars have required an app session or RFID card or credit card swipe, etc. (edit for error on years/fixed)
You don’t -have- to swap accounts if you don’t want to (with your Polestar) but the better question is, why bother? You get FREE charging if your PS2 is a ‘22 and you -should- be able to use that free charging on other cars (I’ve tested this on other platforms and works great; was able to charge my wife’s XC40 Recharge using my Taycan’s free, etc). I’d suggest consolidating to a single EA account either way, as two people -can- use 2x phones to log into same account if desired. Helps simplify your home experience.
