Doesn't seem like it has to be different, right? The Tesla/"NACS" plug supports three-phase.

How? Are you sure? It has two big power pins, one smaller pin dedicated to ground, and two tiny pins that look completely unsuited for power. There's a "mobile connector" that can convert 3 phase, but that has an entirely different plug on the wall side.

I think it doesn't actually, nevermind.

Awesome. This should be a world-wide standard. NACS (Tesla) VS CCS is like USB-A 1.0 vs USB-C with Power Delivery: CCS is unbelievably slow and clunky to the point where it might turn people off wanting an EV once they experience the slow and clunkiness.

A typical EV owner will use CCS a few times a year. Every other day of the year they will use a much smaller J1772 connector with a much smaller cord. Having owned both a Tesla as well as an EV that uses J1772, it's the same experience.

Cars can last 10 or more years. If you buy a car today you're making a bet that Tesla and its standard will still be dominant over all other car and charger manufacturers in the year 2032+. That is an extraordinarily foolish bet. My bet is that within two years Tesla standardizes on CCS for its US cars (thus getting rid of an annoying upgrade/adapter/retrofit problem) and then what'll be left is the sad minority (AKA…

I'd bet a garage will be able to do a connector swap within an hour's labour if Tesla will make the necessary firmware changes.

For legacy cars the likely answer is that people buy the $250 dongle. For new cars this will cost a few hundred bucks in parts and labor (or let's say 1-1.5% of the sales price) and it will be required surgery on your brand-new car.

Who is going to pay for this? If it's Tesla, then the smart move is to put CCS into cars right now (and as a side benefit, standardize their US and European models [edit: nevermind this bit, not the same standards].) If it's the customer, then it's an annoying non-trivial cost you'll have to bear. Yuck.

What "game" are they too late for? The number of ports is the game, and the reason my next EV will be a Tesla. It's very difficult to find charge stations that aren't Tesla, and when you do, they're often used for general parking.

Out of curiosity, where in the US are you? Where I am (Oregon), public CCS charger locations outnumber Tesla chargers several times over. There are huge areas of the state that have CCS chargers, but no Tesla charging capacity. My next EV will certainly not be a Tesla, for that reason.

Tesla Superchargers outnumber all other HVDC chargers in every state, usually by a factor of 2. Maybe you're thinking of the chargers that use the J1772 connector?[1] Those charge via AC, and every Tesla comes with an adapter for them. Tesla also sells a CCS adapter in case you want to use other high voltage chargers such as Electrify America.[2] Though honestly, other charging networks are a shitshow. A friend of mine has an Audi e-tron and he won't drive it farther than Tahoe. Electrify America is too unreliable to trust for road trips.

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.

What is the percentage split of Tesla vs everyone else in NA?

They don't standardize US and Europe because US is CCS1 and Europe is CCS2.

They are all tiny in comparison... The vast majority of EVs in the United States use this now, and it's not just historical - Just to emphasis the most popular EV cars in the US today are: Tesla Model Y 60,271 20% 191,451 50.7% 33.2% Tesla Model 3 55,030 67% 156,357 94.5% 27.1% Ford Mustang Mach-E 10,414 – 28,089 49% 4.9% Tesla Model S 9,171 150% 23,464 79.9% 4.1% Chevy Bolt EV/EUV 14,709 226% 22,012 -11.3% 3.8% Hyun…

But there are already 3x more level 2 + CCS ports than tesla ports. In the US: There are 36000 individual tesla connections There are 92000 l2 j1772 ports. There are 22000 CCS DC fast ports They are comparing the DC fast number to the tesla number, and ignoring the j1772 number.

They are comparing fast charging only, yes. (Also all Teslas come with a J1772 adapter.)

How much cheaper is it to build a vehicle with the NACS port vs J1772 port? If the build savings are enough, I foresee manufactures making the switch.

Why would they switch? Then their customers couldn't access CCS chargers OR the supercharger network. That's not exactly a selling point, no matter how much money they save on the connector.

This won't turn into Betamax/VHS or Blu-ray/HD-DVD because CCS has already won-- every EV sold in the US except Tesla (and maybe still the Nissan Leaf; they may still be on CHAdeMO) has CCS Type 1. This is probably too little, too late for Tesla.

People seem deep in denial about Tesla market share. Tesla is 80% of all EVs sold and still 65% of current vehicles sold last quarter - even with some dramatically cheaper EVs available. As Gigafactories in Austin, Berlin and Shanghai continue to ramp, that's unlikely to change.

Musk pulled Tesla's director of software development, Tesla's director of Autopilot and TeslaBot engineering, Tesla's senior director of software engineering, a Tesla senior staff technical program manager, and a senior manager of security intelligence and tasked them with babysitting Twitter.

As much as I've grown to dislike Musk I'd rather like to see Tesla succeed. By gutting Tesla senior management as well as rank and file Musk is ensuring Tesla's market share is only headed in one direction: down.

You’re confusing the CCS chargers outside of North America. The ones in NA are absolute trash and Tesla is right to try to kill them off as fast as possible before electric car volume that uses them becomes significant. Tesla is well over half of the electric cars. There’s no reason for them to accommodate the absolute worst standard at their stations.

> Tesla is well over half of the electric cars.

Their year-over-year market share is declining sharply, however. They should have tried this move five years ago.

Even if Tesla updates the Model 3 & Y to be competitive on features, the sheer quantity of competition means they were never going to dominate the space. If they choose to keep removing features from their cars instead of adding them, I start to wonder what exactly Elon's vision for the future of the company is.
