If it can charge from 208-277vac input range, I've got an extra J1772 socket you have. My DSR runs 4 of them now with a Tesla destination plug as well.
I noticed that in one of the pictures you sent on Hangouts...
One of my next big hurtles (after I solve the basic BMS riddle again) is to tap into the two primary charging standards.
I have not yet looked... but am guessing... that we are starting to see kits for doing this that are low cost.
I broke open a few level 2 chargers... OMFG... it looks like a project kit from Fry's in there.
NOTHING IN THERE...
Things are like $50 bucks in parts
Once the code sets are mature and open source the price on those things will converge on under $100 for certain.
As for Better Standards...
Like the Tesla Plug
Mmmmmm... yea... who the hell wants a plug the size of your wrist that costs so much?
It is just not needed.
How about good old alligator clips
Nothing like hooking up 350V by hand.
Increasing battery voltage and controller current limit will result in a non linear experience
