Update on using my Open EVSE on 120V/30A TT-30 outlet for charging: I did get a chance to use it twice on my trip last week.achewt wrote:[snip...]
Scroll down to the Charging Equipment section (http://kootenayevfamily.ca/ev-basics/resources/) and click on BSA Electronics - this guy builds high - quality Open EVSE products. I bought one last year and have used it several times now, and can confirm that it will charge at at least 20A on a 120V TT-30 outlet. I've actually never tried 24A, because I was camping overnight anyways and didn't need maximum juice. I should have a chance to try it during a road trip at the end of April and will report back.WetEV wrote:I think you are correct, and I've never seen an EVSE capable of 120V/24A. Most current I've seen in a L1 is 120V/20A:achewt wrote:- Each place only has 120V/30A outlets (that I can find), so if you have an EVSE capable of drawing 120V/24A (not many can), you have about 6+ hours of en-route charging

Perhaps then add a NEMA TT-30, but at least the early 2011 and 2012 Leafs couldn't charge at this current. Can later Leafs charge at 120V above 12A on 120V?
And oh yeah, 3% is wayyyy too close for comfort If my sheet says anything less than 10%, I either slow down or go a different route. Some routes it is incredibly unsafe to slow down on, and I would count this as one of those routes.
First time I charged overnight from almost flat and had about 9 - 10 hours, so I set it at 18A and the car accepted that power with no quibble.
The next day I set the unit to 24A. After 45 minutes, I had not recuperated as much energy as I expected (based on Leaf Spy, dash SOC, etc) - in fact I had only been averaging about 1.7 kW into the battery, despite Leaf Spy showing 2.6 - 2.8 kW. After that though, it picked up dramatically and charged at the displayed rate in Leaf Spy. Not sure why that happened. Delayed me by about a 1/2 hour, which wasn't too bad.
