“Tesla’s formerly proprietary charging port was opened up last year in a bid to become the de facto EV standard in the US.”
Ford, GM and Rivian signed on, ChargePoint followed, and now SAE puts its stamp on Tesla’s plug. The federal Joint Office worked to expedite it, and Washington and Texas will require it at charging stations. A port Tesla alone controlled two years ago is now the spec everyone else builds to. Tesla wrote the standard and its rivals get to comply.
