Thanks Jim and everyone. It sounds like I did everything right. This will make a much better evse to carry around in the car. :D

Does the charging light blink on your EVSE when it is charging? If so, then you should be able to adjust the charging rate as per the pdf guide two posts back. Lemme know if it blinks. I bought mine 3 years ago and it is adjustable.
No it doesn't - The light stays on solid. I remember when they first introduced the adjustable feature (March or April of 2013 I think) - That's when I started this thread telling everyone what a wonderful upgrade this is now that they offer adjustable current

My point is . . . . even with the original non-adjustable upgrade, there's something more to doing this than just removing the varistor and changing the transformer - Don't know what that is - An EPROM reflash? - but until we find out, there's not much use to run out and modify your EVSE if you aren't going to end up with 12 amps

Apologizing for taking so long to find the right sub-forum. I just joined and have had my 12 silver ES for only five days.
My factory unmodified EVSE seems to run at 8A on L1 120VAC. The only time it flashed its green LED was when I plugged it into a poorly grounded outlet. Once that was fixed, it is now just solid green or orange at start up. It never flashes any number of times; just solid on when energized. So has anyone successfully paper-clipped an early non-flashing EVSE and gotten it to flash 12 times in a 15A 120VAC outlet? That is my holy grail question for the moment. Thank you.

I don't believe that's a feature of the unmodified units.

Anybody using a Duosida EVSE or the ZenCar EVSE?
https://www.amazon.com/Portable-Electric-Vehicle-Charger-Duosida/dp/B018A6QK7C
http://www.e-zencar.net/product/evse-32a/

Both are universal 120/240 voltage input, and the ZenCar unit has many selectable amperage ranges. They're Chinese built, non UL-listed as far as I can see, and quite cheap for 16A L2 ($165 shipped). Here's a long thread on 'em. http://www.mynissanleaf.com/viewtopic.p ... 2&start=60

Reason is, now that I have four functional EVs I'm looking at all alternatives for keeping the fleet at individually programmable states of charge. In reality, I'll probly settle on one L2 and three L1 EVSE on different circuits, but intelligent sharing of a single L2 circuit is also appealing. I'd hoped to accomplish this with the EMW JuicePlug(s) as backer #146, but have been waiting on delivery for over a year now......

Another option is a Seattle firm called MainPine, which is a big name in Fax Modems that is diversifying into DIN rail-mounted EVSE controllers that can be programmed for sharing/prioritizing current among many EVs (up to a dozen cars per circuit, IIRC). Picture a single L2 EVSE box with many cables and a smartphone app that provides different charging options at much lower cost than commercial-duty EVSE. More info on that option as I get it...

A guy in Gilbert AZ on ebay is offering the duosida for $200 though I can't tell if has them or is backordering or what. I put a question to him asking if it is user programmable for various amps on 120vac. Not answered yet.
One thing I don't get though...is a US early i-miev limited to 8 amp charge by some setting in the EVSE it came with or is it something in its onboard charger commanding the EVSE to stay at 8? I believe I have seen statements on here and elsewhere the canadian cars charge at 12A from 120vac sockets. Which box is that happening in? Point is that if it is programmed into our USA chargers, then a duosida is not going to do anything but charge at 8A on a USA car. What am I missing here?

The charger will pull whatever the EVSE says it can give, up to16 Amps max whether 120 or 240 VAC. My main EVSE is the Bosch Power Express (originally by SPX), which was the first EVSE with universal 120/240 input and adjustable amperage limits between 6 and 32 amps. Unfortunately it's as big as a shoebox, heavy, and not waterproof. I used it in the wilds during 2012 road trips, but not much since, given our decent infrastructure here in Western Washington.

The EVSE that came with 2012 US i-MiEVs is an 8 amp, non-programmable unit. As with all EVs, any current limiting below the charger's max power is controlled by the EVSE. The i-MiEV's stock EVSE will only charge a Tesla at 120 volts, 8 amps, for example.

Newer i-MiEVs ship with an 8/12 amp EVSE that is capable of charging the car faster.

Many of us had our 8 amp units upgraded to support 120/240 volt charging at up to 13 amps. A company called EVSEUpgrade performs these upgrades. Their units with the blinking lights are capable of being paper-clipped and have the current adjusted. I had one of my EVSE cables upgraded to do this and I use it as my main means of charging.

Jiminy wrote: Thanks for the good words. I will ponder offering plug and play power supplies that allow for 240V AC Level 2 charging. I forgot to mention that after the changes are made inside the EVSE case, the unit is still perfectly functional as a Level 1 EVSE. If you put on a 240V plug you would then need a wiring adapter to go from whatever you used on the end of the cord to a 5-15 120V AC receptacle. If you left the 5-15 plug on the end of your EVSE it will still work at 120V as-is. Not sure why you would want to do that but it works nonetheless. And remember, this is not my design. I just copied exactly what EVSEUpgrade did.

Here is my modified Nissan EVSE with a Nema L6-20R to 5-15P adapter:

Did you look inside the plug to see if they added two varistors across the lines to ground? If EVSEupgrade removed the internal MOV, then one or 2 would be needed somewhere in the AC input line to perform the same function.

They install a molded twistlock plug on the brick so I'm pretty sure there's been nothing added inside the plug and looking at his photos, I don't see where they added them internally either
