Indeed. All US market Leafs have always only included a J1772 inlet for level 1 and 2 AC charging (120 to 240 volts) and can include an optional CHAdeMO inlet. When doing AC charging, the external unit is an EVSE, not a charger: http://www.mynissanleaf.com/viewtopic.p ... 30#p262630

and https://openev.freshdesk.com/support/so ... -sae-j1772
. I believe European market Leafs before model year '18 also included a J1772 inlet but provided a Mennekes Type 2 to J1772 cable since there's no J1772 in Europe and common public and household charging is over Mennekes Type 2. There is no Mennekes Type 2 in the US.
Some EVs in Europe (e.g. Renault Zoe) can utilize much faster and higher wattage AC charging via 3-phase power (also over Mennekes Type 2 connector). I'm not clear how commonly available this is at commercial locations in the US but is certainly not common at home. No mass-market for consumer EVs and PHEV for the US market have any sort of inlet for 3-phase power charging. Renault also pulled out of the US market ages (at least 25 years) ago.
I'd heard some rumors that '18 Leafs in Europe or some parts of Europe might include Mennekes Type 2 inlet but I'm not clear. https://www.nissan.co.uk/vehicles/new-v ... rging.html
doesn't make any mention of charge rates above 7 kW.
You will need to use the CHAdeMO inlet to achieve a 22kW rate and yes it is 400Vdc.
Sure looks like it.
Last page of https://www.nissan-cdn.net/content/dam/ ... 018_UK.pdf
mentions only 6.6 kW OBC. It talks about 50 kW quick charge but that's almost certainly CHAdeMO.
