Except pretty much everyone thinks the CCS2 connector sucks compared to the Tesla connector. The EU ought to mandate the Tesla connector instead. We're still in early days, no need to worry about the tiny number of cars that have already shipped.

Type 2 supports 3-phase AC, something both CCS combo 1 and NACS don’t. That alone would make a transition in Europe a terrible idea, especially since the Tesla connector doesn’t even seem to have a path to 3-phase support.

Yes, Type 2 Combo 2 is a bit bulky, but otherwise it’s perfectly fine.

Three phase is a red herring. No consumer needs to use all three phases to charge their car at home overnight. You’ll wake up to a fully charged car every day on single phase, as the vast majority of us do. Same applies even with the slightly weaker current per phase on continental Europe.

The parts of Europe limited to 25A would still allow for a full overnight charge. The EU voltage is 220V, so 25*220 = 5.5kW. Assuming a 75kWh usable capacity on the Model Y, that means the rare occasions where you’re charging from 0-100% overnight would take 13.6 hours.

The real test of charging hardware is on long journeys where we want to keep the charge time to a minimum, and where Tesla’a NACS 1MW capability is a huge benefit to consumers vs CCS

If you believe the EU’s CCS mandate is a good thing, you’re not paying attention

The Renault Zoe can do 22 kW AC charging. There are public AC chargers too. They are cheaper to deploy than DC chargers.

So.. you claim no consumer needs "all three phases" for AC charging but now you're insisting consumers need 1 megawatt DC charging on passenger cars, cheerfully ignoring the fact that there is no deployment of 1 megawatt chargers for passenger vehicles and no current passenger car can sustain 1 megawatt charging at any part of its charge curve.

Make up your mind. And while you're making it up, understand that there's nothing preventing a revision to the CCS type 2 Combo plug and cable standards to spec faster charging. The Tesla plug is just about the cable and plug. It's the least interesting part of any charger.

I'd like to pay attention to your manifesto on how CCS type 2 Combo is a bad thing when the European EV market is bigger than the North American market, when all brands of charger charge all brands of EV in Europe, when CCS type 2 Combo is deployed in many countries outside of Europe, and when 400 kW CCS chargers are being deployed while Tesla's chargers still max out at 250 kW:

> 400 kW CCS chargers are being deployed while Tesla's chargers still max out at 250 kW

The EVBox literature discusses 400kW per station, but each station has two CCS cables that can share that power. Since the max power delivery of CCS2 is 350kW I suspect EVbox are clickbaiting their headline and the truth is that 400kW is only delivered across both connectors (200kW each), not to a single connector.

Tesla’s V4 Superchargers, on the other hand, can deliver 600kW, and have been rolling out since March. The Tesla NACS hardware can carry 1 megawatt, unlike CCS2’s 350kW.

It is not.

> Tesla’s V4 Superchargers, on the other hand, can deliver 600kW

Gee golly! Let's see how well that works currently:

Hmm. Outperformed by other chargers and even outperformed by a Tesla V2 charger. Pretty lame. Tesla must try harder.

> The Renault Zoe can do 22 kW AC charging. There are public AC chargers too. They are cheaper to deploy than DC chargers

Maybe ten years ago, a 22kW public charger might have seemed reasonable.

Now public chargers operate on DC, at 350kW and beyond, it seems a bit anachronistic to be discussing 22kW AC public charging.

> So.. you claim no consumer needs "all three phases" for AC charging but now you're insisting consumers need 1 megawatt DC charging on passenger cars … make up your mind

I think you perhaps misunderstood the distinction I made between home charging (single phase AC is fine, as we can leave the car overnight) and public charging, which is relied on during long journeys, and for which 100kW+ DC is essential for practicality.

> public chargers operate on DC, at 350kW and beyond

Beyond, you say. What, you mean like 400 kW Alpitronic chargers?

How are 400 kW chargers being deployed to the field?? Is it a conspiracy? Is it those mysterious Them?? Are They doing it?

> understand that there's nothing preventing a revision to the CCS type 2 Combo plug and cable standards to spec faster charging. The Tesla plug is just about the cable and plug. It's the least interesting part of any charger.

Revising the cable and plug IS the complicated bit, actually, when you run a network of EV chargers and you’re the one paying for the hardware and labour costs

The Tesla NACS hardware is megawatt capable. CCS2 hardware is 350kW capable.

Let’s not pretend it would be trivial to upgrade CCS2 to megawatt capability, with so much legacy deployment to upgrade.

> Revising the cable and plug IS the complicated bit, actually,

It is not. CCS has had one revision already. You also seem to be misunderstanding that all that's going to happen is Tesla's plug will be put on CCS chargers, just as Tesla chargers have CCS type 2 combo plugs on them.

Tesla's chargers talk CCS. They are CCS chargers. How do you think they work in Europe? How do you think they're going to charge all cars in North America?

> CCS2 hardware is 350kW capable.

Sure, kid. That's why those 400 kW CCS chargers exist.

> Let’s not pretend it would be trivial to upgrade CCS2 to megawatt capability, with so much legacy deployment to upgrade.

Charger cables get replaced all the time.

> That’s why those 400kW CCS chargers exist

If you think CCS chargers exist that can deliver 400kW to a single connector for a passenger EV (as opposed to 400kW shared across two connectors, or specialist charging hardware for semi-trucks) then by all means, edit the opening paragraph of the CCS Wikipedia page (“350kW” -> “400kW”) and let’s see how your revision goes down with the experts that frequent that page:

Incumbency doesn’t imply a superior standard.

CCS2 is winning in Europe not because it’s better than NACS, but because a technocratic EU committee decided it would win, many years ago.

> Incumbency doesn’t imply a superior standard.

Superior results imply a superior standard. All brands of charger charging all brands of EV is a superior result. Anything less is substandard, backward, and primitive.

I think you confuse winning on merit with winning by regulatory mandate.

I prefer the former, you prefer the latter. Let’s agree to disagree. We clearly don’t have much intellectual common ground here.

3-phase is not really for consumers. It’s for commercial and fleet operations where a 3-phase AC charging setup can deliver far more power with much lower amperage circuits. When installing chargers for an entire 15+ storey apartment building or making sure a fleet of 10+ vehicles can all charge overnight 3-phase suddenly makes life a lot easier and can reduce the cost of install significantly.
> Except pretty much everyone thinks the CCS2 connector sucks

They don't, it doesn't, it works, and it's deployed internationally on all cars and chargers.

No point making up a false narrative.
