EVs will always charge at the lowest of either the EVSE maximum output or charger in the car, in the case of only charging at 12a @ 120v with your Juicebox it's the car limiting the charging to 12a. The same EVSE hooked to a 6.6kw Leaf charger would draw 27.5a @ 120v(or whatever you've set your Juicebox maximum output to but not more than 27.5 as that's the maximum the Leaf will accept).
I'm not aware of a maximum J1772 current using 120v but I'd assume it would be the same as 240v, whatever that is.
Think I got it. Its not a power thing, (3.3K) its a current thing. Regardless of 240 or 120 it will limit to 12 amps (technically I think 11.7 or something like that) Is that right? Eg if I want the full three 3.3 KW I need to be on 240 volt.
Correct, to get 3.3kw you need to use 240v.
Thanks for staying with me on this. It' wasn't the math or the physics that I was struggling with (technologist by trade) but the design limitations and understanding what was doing the current limiting that I wasn't sure of.
