[Please make contact with http://evseupgrade.com/ to confirm what I post about them.]
My last dialog with the evseupgrade folk was that the emergency/level-1 EVSE that comes standard with the Leaf EV can only run off ~120VAC and it only draws 12A as that is all the Leaf will pull when running off level-1. They offer two upgrades to that EVSE one that converts it to also run off 208-204VAC at 12A, and another that does the same but max's out at 16A, the most a gen1 Leaf on-board charger will pull. The maximum amount of 240VAC current a gen1 Leaf will pull is 16A according to their spec sheets. But in kW, that depends on the supply voltage. @240VAC x 16A = 3840W, @220VAC x 16A = 3520W, @208VAC x 16A = 3328W. http://www.mynissanleaf.com/viewtopic.php?f=8&t=3010&p=248307 A DS-50 was designed by evii for use with the old Avcon coupler to supply 32A from a 208-240VAC 40A breakered source. Its wiring should easily handle a 16A AC current load. If what you have done is make a j1772 EVSE from an old DS-50 Avcon EVSE, I would crimp my power wire connections, not solder, even though for right now you are only planning to draw 16A. You never know if someone tries your home-brew on a plugin that will have a higher than 16A current load. The Silicon Valley EAA Chapter member Electrician I talked to about converting old Avcon boxes to j1772 to save a $, said by Electrician code, power connections are to be crimped. IMO: though you make get away with a good and solid soldered connection, at shows or EVents if the opening of your box and an Electrician inspection were required for the show to go on, it would not pass. I had an inspection happen to me with a similar adapter box use at a show in downtown San Jose (next door to the Tech Museum) many years ago. They would not let our EVs (Production or conversions) plugin until the site Electrician was satisfied (the Electrician had the last say, yay or nay). Crimping is just not that hard to do, thus I recommend it in these situations to avoid future unforeseen problems. {brucedp.150m.com} - On Fri, Jan 18, 2013, at 09:28 AM, Lawrence Rhodes wrote: > I think the Leaf draws 16 amps at 240vdc.
