Supercharger - Sparks, NV

That is what he is saying. In the Tesla app in the "charge your non-Tesla" section it lists the chargers as up to 250kW. But Tesla is limiting the charge current to 350A. Therefore, the MagicDock Superchargers won't deliver more than ~140kW to a non-Tesla even though Tesla says up to 250kW. So, Tesla is in fact doing it wrong. There is no way to get 250kW out.


At least on the 200A limited cables you, assuming your vehicle supports it, you can get ~200kW out. But yeah, a lot of CCS chargers are really mislabeled, but that doesn't mean that Tesla should mislabel their chargers as well.

They just copy and pasted the “up to 250kw” from the Tesla charging page. To a web/app designer, why wouldn’t they charge at the same rate? Not giving them a break but just pointing out what likely happened when they created the charge your non Tesla page.

Sorry my equipment is lacking even dusting off some old zoom lens. My blurry text processing seems to read CHARGER, 387 kVA @ 480VAC, 4 OUTPUT, 1450758-00-G, OCTOBER 2022, 465 A:

That manufacture date does match up with the equipment spotted on site back in November 2022. But maybe it's also confirmation bias after seeing 1450758-00-H used at Reno Rancharrah manufactured February 2023 and on site March:

Thank you for confirming that they didn’t swap cabinets. V4 cabinets do not exist. They are not being used for installs at this time, especially not at a pedestal upgrade site like this.

Presumably cabinets being able to switch between 500v and 1000v is a well understood technology since CCS cabinets do it all the time, right?

Yes.

Fast chargers don't exactly switch between 500v and 1000v like they're two separate operating modes. The charger always has to exactly match the pack voltage of the car. So on a Tesla thats usually in the 300-400v range. On an Ioniq 5 it's 500-600v (apparently, from a quick google search).

The voltage varies across pack state of charge, so while charging the fast charger has to continuously adjust the applied voltage very precisely to push however much current the car is asking for.

When we talk about supporting 1000v what we really mean is the charger needs to support voltages up to 1000v. The charger is still matching pack voltage and continously adjusting while charging; it's just not limited to 500v like current Superchargers are.
