Telsa's proposed, future v4 standard is still only capable of 250kW and meanwhile CCS stations have been deployed for years now that can do 400kW, with 700kW chargers being demonstrated.
It's an outdated, proprietary standard in both form and function, even if Tesla claims it's a public standard; they exert total business control over the plug and their charger network. There's no way they'll allow a random car to plug into a supercharger ('safety' and such), no way they'll allow any other payment methods on their network. There's no way they'll support configuring your Tesla to work with third party NACS chargers and payment systems.
The only chargers that exist with NACS connectors are in one country and controlled by Tesla. The only cars with NACS plugs are (at the moment) Teslas and the only proposed additional users are companies that have signed agreements with Tesla.
This is why it's so infuriating that Ford, GM, and Tesla did what they did. They just effectively killed CCS, and thus dealt a major blow to EV adoption in the US for the sake of a market share grab. 800v architecture meant EVs finally could lay claim to being practical for long distance charging. Plug in at a rest stop, everyone hits the bathrooms, maybe a snack, stretch their legs, and the car is nearly full again. A lot of errands and such fit into the 18-20 minute window a nearly-full-charge takes. "NACS" can't offer anywhere near a 18 minute 10-to-80 charge.
The US version of CCS is far from perfect; the weight of the cable causes connection issues due to the poor mechanical design of the socket, and we never should have had a unique CCS connector from Europe to begin with. But Tesla's "North American Charging Standard" is outdated and their supercharger network in addition to being outdated has been woefully underfunded and undersized for a while; with Ford and Chevy piling onto the network, that's going to get even worse.
What's even more infuriating is that in Europe, there is no such thing as "Superchargers", because the EU forced Tesla to use CCS2. And meanwhile, congress hasn't even noticed that Tesla just effectively captured the US EV charging market.
Ask yourself this: what could possibly go wrong giving the world's richest man - an unhinged narcissist to boot - exclusive control over how electric vehicles are charged in the US?
This is incorrect. I’m not sure where you’re finding 250kW as the max for a V4 Supercharger but they’ve been shown to charge at more power in the wild.
"CCS stations have been deployed for years now that can do 400kW"
There is no reliable CCS network in existence in the US. Can you show me a video of someone using these mythical chargers at 400kw to take a long road trip?
Ask yourself this: what could possibly go wrong depending on Electrify America who only exist due to court ordered action and have no incentive to actually do a good job?
CCS1 has no advantages over the Tesla plug. If we're not going to use CCS2, we should use NACS.
You're wrong about the limits. v3 is 250kW, and the limiting factor is the vehicle voltage. Take it up to 800 volts and that's already 400kW. Pushing the amps above 500 is possible for both connectors, with similar levels of difficulty.
