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.
- sokoloff 2y agoI’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.
- MengerSponge 2y agoBecause if you use the wrong terminology it's more clear, but SAE J1772 specifies two levels of DC fast charging.
- recursive 2y agoNo one calls DC fast-charging "level 2". It's a mistake. Let's not confuse the issue by starting now.
- MengerSponge 2y agoI dunno what you want to happen here: SAE J1772 refers to level 1 and level 2 DC fast charging. https://en.wikipedia.org/wiki/SAE_J1772 https://en.wikipedia.org/wiki/SAE_J1772
- recursive 2y agoI stand corrected. Someone has called it that.
