Wow. Awesome!

I hope Ford and other EV Manufacturers make retrofit kits though - and similar for the charging stations already deployed. Lugging an adapter for all non-Tesla EVs before the, what, 2024 model year would be irritating. Assuming, of course, they are on board and this doesn't turn into Betamax/VHS, Blu-ray/HD-DVD, or HDR10+/Dolby Vision again.

It's just a connector. Why did CCS have to be twice as big then? What's the tradeoff CCS took?

Edit: I just looked up a size comparison of CCS vs Tesla/NACS and what the heck happened...

Why is CCS so absolutely enormous and so technically limited? What's the story behind how it got so bad? There must be some kind of trade-off Tesla took that CCS didn't?

TLDR CCS wanted to be backwards compatible, while Tesla planned fast charging to be first class with their standard. At the time, no one was doing fast charging at Supercharger currents (150kw). CCS was bolted on to J1772.

CCS was backwards compatible with existing standards, and added stuff to it.

It would have been like USB-C being glued to the top of an old SCSI connector.

Tesla controlled both ends (literally) on theirs and so they could optimize for size/etc.

I don't see anything here indicating that other manufacturers will start using the Tesla connector. Unfortunately we're already well into the format war with two standards: Tesla and Everyone Else (CCS).

Honestly this feels more like a desperate attempt by Tesla to push back on the trend towards CCS instead of a substantive announcement

For context, North America's current "standard" is CCS1, which is not the same as Europe, which uses CCS2. So North America already has its own weird plug. The Tesla plug is definitely better from a usability perspective. Very curious to see if there is a major technical advantage for one or the other.
