Everyone time I read a low charge time, the thing that comes to mind is the ability of the charging cable to carry that much power that quickly. Minimally that means you’re delivering 6x the electricity (2x the amount and 3x as fast). I’m assuming the charging is pretty efficient, so you have to scale up the charger, and a bunch of issues start coming up. For this reason I think 10m charge times are bs.
There’s a Starbucks I frequent where the drive through is on the same side of the building as the electrical service (!?) and every time I’m waiting for coffee I look at the multiple 2-3 inch conduits and think what kind of equipment are they running in there? They share a building with another business that I don’t think would put a dent in the power usage for the building, unless they have a server room I don’t know about.
I could run a class 2 charger at my house and that’s only a 1” conduit, but those take half a dozen hours to deliver that current. You’re gonna need a lot more shielding.
Class 2 would be 9 to 10 kw. For reference 33 kw is around requires cables in the us roughly 1 - 3/4 inch conduit. Each piece of equipment requires its own circuit so you likely have multiple circuits in the conduit depending on code. All that said commercial cooking and refrigeration require a lot of power.
Going back to charging, for a circuit the size this would likely need your be looking at something with at least 3 1 inch wires, and would be at least 2.5 inches in diameter when packaged. It likely needs cooling too which means even more diameter.
