Level 2 can charge up to 19kW (240V at 80A) but 12kW (50A) is more common. NACS also can't do three-phase power. Three-phase power is rare in the US, it is only found in commercial locations that need it.

How does the US get to 240v if you guys don’t have multiple phases at home? Not an electrician, but here In Europe we get to 400v by combining the three 240v phases we get.

US power is really 240V with a neutral. It’s wired to most outlets and circuits as one 120V leg (against the neutral). But you can absolutely wire a 240V circuit using both legs and major appliances (air conditioners/heat pumps, electric driers) use 240V. My Tesla charger is on a 240V 60A circuit.

They all speak the CCS protocol so it’s a matter of a simple passive adapter.

At some high level of charging speed, won't the adapter need active cooling and temperature monitoring?

I wouldn't imagine so; a short, rigid adapter could have very thick conductors which would have low resistance relative to flexible cable. And being a passive adapter, it would be easy to make very heat tolerant.

I just got on Intact’s website and got a quote for one John Smith, 18 year old male from Branford, Ontario. John wanted a quote on a Tesla Model 3 Performance. Their quote was $3200/year. You want to try and explain why it is that you are getting quotes that are twice that of the highest risk drivers?

You are right. I mistakenly failed to pay the parking meter on time 7 or 8 years and was issued a ticket. Of course I threw myself at the mercy of the courts; a simple mix up of days I pleaded. It was not the statutory holiday I thought it had been that would have waived the parking fees. And I paid my ticket immediately. But they would have none of it. So unforgivable was my crime, so heinous, so far murder or rape,…

Are your electric lines all buried? I guess if they are that would make it much more difficult. Otherwise, you have poles or something to keep the lines in the air. I'm just amazed America has so much free parking still. People buy houses, even if they have garages, they use the garage as storage and park their car on the street. Having lived in other countries where that simply can't happen, its like this country pr…

Yes, utilities are all buried. Electrical doesn’t even come from the street side of the house, it comes in from a utility corridor behind my house. Also have a garage, but isn’t practical to park in it for various reasons, some more fixable than others. (It’s set up as a home gym which I view as essential for my health, it’s single car and parking in the driveway would block in the garage, it doesn’t have a floor dra…

Seattle has lots of garages like that, so much so that they no longer dig basements for new housing (lots of old garages are basically a decline to a basement with a garage door). Seattle is one of those cities that doesn't enforce parking minimums, so street parking is otherwise over prescribed by new dense housing projects going up (unlike say LA).

I don't think street parking is sustainable. We build denser, and without parking, it is eventually going to fall apart where too many people are going to be fighting it out for too few street parking.

Chademo supports bidirectional charging. But bidirectional charging means you basically need a DC fast charger, and those are like $10k. (Hard to find an actual number online besides Alibaba… it’s always an “inquire for price” email quote button… which tells you it’s gonna be like $10k.) By far the easiest way to pull power from an EV is from the 12V subsystem. The DC-DC converter for EVs usually is like 2kW, so it’s…

Cheapest Chademo bidirectional V2H equipment for home in Japan costs 500k JPY https://etex.jpn.com/info/v2hhojyo/ https://www.nichicon.co.jp/products/v2h/about/specs/

What's the price of the inverter on the other end? Installation?

The problem is obvious though, isn't it? Our current infrastructure simply cannot handle a ton of EV's all wanting to charge up all day long - as is done currently with gas stations all over the country. It'll take decades to bring our infrastructure up to where it needs to be to support this - yet people act like we're already there. Some states still struggle just to keep the lights on during major parts of the yea…

The load is spread out in a completely different way than gas, because 100% of gas cars get gas at a station, while 80% of people with EVs slow-charge at home (or work or whatever). Fast chargers are for road-trips only. Obviously, if we're going to move to cleaner energy we will need infrastructure investment. Worrying that it's not already there makes no sense. The demand for improved electrical infrastructure will…

> while 80% of people with EVs slow-charge at home

Suure... because 80% of people own a home where they can do heavy electrical modifications, and can afford the permits and the work.

Not sure where you think that is, but in USA that it not even remotely true.

So why is everyone fleeing the North American standards J1772/CCS1 in favor of Tesla's? What do these car companies stand to gain switching the charging port? They don't own charging networks.

Their agreements with Tesla are not public, so it's hard to tell what the benefits are. You say "everyone" is switching, but it's only American companies that have pledged to switch to NACS from CCS (so far), I don't think 3 for 3 is a coincidence. Also unlikely to be coincidental is the fact that Tesla "opened up" its charging patents/specs to competitors [1] in 2014 - but only signed its first partner in 2023, a fe…

The major benefit to Tesla here is that it pushes most of the costs of unifying the continent on a single standard upon third party charging networks. Ford and GM have minimal exposure to that, so they don't care, and it saves Tesla a lot of future heartache.

And it's a sensible move if you care about e-waste, given that there are far more NACS vehicles and NACS charging stalls in than CCS1 vehicles and CCS1 charging stalls. (And that contrast becomes even more extreme if you assume that the thousands of unreliable CCS1 stalls would be getting scrapped anyway.)

Meanwhile Nissan and Mitsubishi are still selling brand new cars with CHAdeMO plugs. So much for it being a universal standard.

What charge port do you have that isn't Tesla compatible with an adapter?

AFAICT, unless you're in San Francisco, Sacramento, or New York there is currently no adapter that will let a non-Tesla vehicle use a supercharger.

That's because much of the Supercharger network was deployed with the assumption of only supporting Tesla vehicles. If any third party charging network deployed NACS fast charging stalls in your area, they would absolutely be compatible with any CCS1 vehicle with an adapter.

Would something like a TeslaTap work with a 350kW charger? Or do new adapters need to be created?
