I know that the European Union insisted that Tesla conform to the single recharging plug/receptacle system already adapted among European EV makers, the SAE J1772/CCS plugs & receptacles. But I don't know what details Tesla agreed to. I had thought that Tesla agreed to use the EU standard that already exists. If so, it doesn't make any sense to do the opposite in the USA, to adapt the so-called North American Charging System (NACS), previous known as the Tesla plug.
Even though my EV uses the J1772/CCS plug, I don't really care whether the J1772 or Tesla plug system becomes standard, as long as there is one standard plug. Yes, the Tesla plug came first as there was no existing standard at the time. But until recently, Tesla made it exclusive to Tesla EVs. Now that Tesla has real competition, it wants to sell licenses for access to it's large network of Fast DC chargers. This Elon Musk-induced argument is as dumb as the various format debates (Mac vs. Microsoft Windows, Betamax vs. VHS, and the various Blu-Ray vs. what were those other formats?) we've seen in the past. It benefits only corporate executives & lawyers, while delaying the use of one common charging plug system.
Below are diagrams of some of the various charging plugs: the
SAE J1772 (standard for Level 1 or 2 AC charging on all but Tesla until recently?), CCS1 plug (combines J1772 with 2 large contacts for Fast DC charging), Tesla Supercharger (combines AC and Fast DC charging), and the CHAdeMo plug (seems to be fading away).
