Tesla’s plans to open its Supercharger network to accommodate other electric vehicles (EVs) is facing delays due to the unexpected layoffs within Tesla’s Supercharging team. Originally, Tesla had announced electric vehicles (EVs) from General Motors […]
We had the opportunity to choose a standard and nationalize the infrastructure and we fucked up yet again

Yet there’s delays because of Tesla
Nowhere in the article or the other article does it explicitly say it’s because of Tesla. It does say that Polestar and GM have made the announcements of the delays.
First freaking paragraph

The article is about them delaying other manufacturers from accessing their network so it’s not as open as they want you to believe.
The connector is open, Tesla’s charging network is not.
So we fucked up

It’s in the first paragraph

So yeah, we fucked up
My first message was that we should have chosen a standard and nationalized the infrastructure, the industry chose a standard, the infrastructure is private and now things are fucked because of the company that invented the standard.
No other network uses the connector currently.

Which network has their chargers equipped with NACS handles besides Tesla, and is currently deploying them.
NACS connector is dog shit, and still uses the CCS communication protocol. If we were going to change the whole industry, we should have changed to something that offered 3 phase power as an option. But the lemmings took what they perceived as the easy option.
They fucked around and now they’re going to find out.
SAE J3400 does support 3 phase power, which is great!
No it doesn’t. NACS is the two power pin, pilot, and proximity. No three phase is supported. You may want to actually buy the spec like I have before making things up like this.
I’m no electrical wiz, but it seems like we’re dealing with a misunderstanding?
When I hear “3 phase support”, I jump to it can be powered by at least part of a 3 phase supply without transformers. Which is what they clearly state in multiple sources:
I am not sure I understanding you correctly, you wanted them to feed all 3 phases to charging EVs? Batteries are DC, wouldn’t that mean sticking a heavy 3-phase to DC converter in the car?
So you don’t understand what 3 phase means, which is totally okay. Just say that instead of making up an incorrect answer. Saying “powered by at least a part” isn’t three phase, that would be single, two, maybe split-phase like normal North American domestic power.
The other issue you have here is that J1772 is rated for 300v, just like J3400 is rated for 300v. It’s a software choice, and an EV plus connector that support increasing voltage don’t need a new connector. In fact, adding 277v support to J3400 will require J1772 support anyway. J3400 is simply J1772 with a new form factor proposed- same as it has always been. But it combines the DC pins from Combo 1 into the existing J1772 / J3400 pins.
Yes.
What does this have to do with anything? You’re already converting split phase AC into DC, using 3 phase (already done in this place called Europe, BTW) delivers more power at the same amperage.
Yes. Again, see all of Europe.
What is the actual issue you’re trying to solve here in the US? We simply don’t have the prevalence of lower power 3 phase systems like Europe does. Are you worried about unequal legs for commercial operations with tons of L2 chargers? Can you be more specific about why adding 3 phase inverters to all the cars in the US would be a benefit when we already have access to single phase everywhere, or 3 phase L3 chargers that can just feed us DC (anywhere from low to high power)? I’m just not seeing it.
I’m not trying to solve for anything except a unified connector. The upshot of which would be supporting all three phases of a three phase branch which is something that NACS mentions while only using two of the phases from a 480v system. Using all three means onboard chargers and connectors could be the same globally, and when using split phase power in north america, the onboard charger would still work completely fine but at a lower voltage.
