This is starting to feel like... the XKCD meme about too many standards. Everyone in North America that isn't Tesla: CCS1 Telsa in North America: NACS Everyone including Tesla in Europe: CCS2 Everyone in Japan: CHAdeMO Everyone in China: GB/T

Not really. Tesla is already the vast majority in the US. They are just opening up to try to kill of an already existing worse standard.

https://news.ycombinator.com/item?id=27907051 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.

That really doesn’t explain all of it, J1772 is not really that big. CCS adds a ton of bulk on top of J1772.

J1772 can't carry enough amps through those pins. So it needs two more huge pins in a separate compartment.

CCS isn't the absolute smallest way to add two more huge pins, but it's pretty close.

I don’t know that this is “instead of.” That isn’t stated anywhere. Tesla has also committed to building Superchargers with CCS connectors.

This has happened in some European countries, but as far as the US, it remains all talk; the large amount of Tesla superchargers everywhere remain unavailable for those of us with CCS vehicles. This move seems very much like intended to ta…

Every Supercharger in EU is CCS, afaik.

Tesla is at least 5 years late here, maybe more like 10. All of the US federal funds will likely go to CCS now because they stuck to the proprietary network strategy, despite the OBVIOUS and natural social utility from an open industry-wide standard and charging networks open to all.

For reference here is the DOT's NPRM from June laying out the proposed requirements for states to receive federal funds from the infrastructure package: https://www.federalregister.gov/documents/2022/06/22/2022-12...

What legal guarantee is there that Tesla won't reverse course in the future? Say a charging station or car manufacturer adopts this connector and then in 5 years Tesla says "well actually, we've got these patents and we're going to start charging you to sell cars/charging stations"? Publishing the specs and saying "we won't enforce patents" isn't a legally binding guarantee

I'm not a lawyer but that sure sounds like it would be a case of promissory estoppel to me. That is, if someone relies on Tesla's word and makes investments based on it they'd have a legal case to prevent Tesla from trying to exercise those patents against them. But I do hope there's an actual legal grant of rights as well.

Haven't heard the term and I'm googling it to understand better. Is there case law where this was tested in the context of patents on ports? I'm thinking Tesla could say, "we changed our minds but you can keep selling any of the Toyota 2023 models, you just can't make a new car model with the port. therefore we aren't causing you financial harm or injury by relying on our promise"

The T.C. video is very thorough and worth a watch for all EV related shennanigans.

That's most T.C. videos I've seen. Often niche topics but I sat* through (and enjoyed) 20 minutes of why an obscure can opener is superior than the mainstream ones.

Also why the best toaster was created in the 50s, how petrol lamps work, the wild story of video on discs, and dumb US. automotive standards (or less dumb ones). Followed by a speed run through the entire history of analog photography.

It’s wild not just how varied Alex’s interests are, but how he’ll find interest in the most mundane subjects (christmas lamps) and how well and thoroughly he’s able to present them.

The press release says: > we are opening our EV connector design to the world. We invite charging network operators and vehicle manufacturers to put the Tesla charging connector ... equipment and vehicles This does not even promise that it is free. "open" and "invite you to X" sound good but are very vague.

Yeah, Apple has used similar language in marketing for their Lightning Connector licensing program.

Tesla said in May that it would be adding CCS adapters to its Supercharger stations, already used in Europe: https://electrek.co/2022/05/10/tesla-add-ccs-connectors-supe... Now they're trying to declare their own charger as a "standard", after launching a $250 adapter in September to use the actual standard plug? Also, obligatory Technology Connections video: https://www.youtube.com/watch?v=sZOuz_laH9I

I think it's a good strategy given how people are standardizing on CCS1 in NA. They're embracing CCS1 to a large degree, offering adapters for plugging your car into a CCS charger and allowing CCS cars to charge at Superchargers. But the connector is definitely better, so they may as well open it up in the hopes that people adopt the nicer plug and then they won't have to change it after all. Basically no reason not…

> and allowing CCS cars to charge at Superchargers.

I'm reading the announcement differently. They are saying future non Teslas who adopt NACS can use the Tesla chargers. It doesn't say anything about current CCS cars being able to use Tesla charging.

Doesn't really matter even if it's slightly technically better. We are WAY too late in the game here (US is already deploying federal funds!), and they should have engaged with open standards a decade ago.
