> near the limit of what's practical without using a fast charger

"fast charger" usually means one of those fancy DC systems, not just a bigger outlet.

Confusingly, Level 2 charging can refer both to 220V AC or fast DC charging. Context is key, but home level 2 (AC) can get up to about 20kW, while DC Level 2 easily delivers up to 400kW.

"Fast charger" in the context of home charging means 20-50A at 220V, which is enough to fully charge the battery in a few hours. Basically, you can roll in on fumes at midnight, plug in and go to sleep, and wake up and leave the next morning with a full tank.

No one calls DC fast-charging "level 2". It's a mistake. Let's not confuse the issue by starting now.

I dunno what you want to happen here: SAE J1772 refers to level 1 and level 2 DC fast charging.

I stand corrected. Someone has called it that.

I’ve always heard DC Fast Charging called “DC Fast Charging” or “Level 3”. I don’t think I’ve ever heard it called Level 2.

Because if you use the wrong terminology it's more clear, but SAE J1772 specifies two levels of DC fast charging.
