The current Level 1/Level 2 EVSE supplied with the US Nissan Leaf fully complies with the current NEC, I believe.

Do ANY of the "EVSE Upgrade" Nissan EVSEs similarly fully comply?

Does anyone want to discuss the "pros and cons" of the safety aspects of NEC compliance for EVSEs?

The first generation EVSE Upgrade pulled 16A on 240V. I thought the plug was an L6-20.
You are correct; I think @GerryAZ just had a typo ;)
I still use my 2011 vintage EVSE upgrade coupled to a 220v Modlet (from thinkecoin.com) to monitor power consumption to this day. I built my own NEMA 10-30 to 6-20 adapter cable to use the old "dyer" plug in my garage.

Yes it was a typo. I fixed my previous post. The very first generation came with L6-20 plug and would allow 12 amperes at any voltage. The next version would allow 16 amperes, but 2011 and 2012 LEAFs would only draw 12 amperes at 120 volts.

The EVSE Upgrade that was done in April 2015 to my original Nissan unit kept when the 2011 was totaled essentially complies because it has a short cord (not more than 12 inches) with L6-30 plug and allows a maximum of 24 amperes on 208 or 240 volts. It allows a maximum of 12 amperes at 120 volts so an adapter for standard 15-ampere, 120-volt receptacle does not cause an issue except the overall cord length exceeds the 12-inch maximum requirement. The current settings can be set in 1-ampere increments from 6 to 24 amperes at 208 or 240 volts and 6 to 12 amperes at 120 volts if it is necessary to reduce the charge rate.

Personally, I disagree with that 12-inch maximum cord length requirement because it can be difficult to find a way to support the body of the EVSE so it doesn't hang by the cord. A 24-inch cord would be safer because it would allow the EVSE to rest on the floor.

Incidentally, the Nissan dual-plug unit works fine when plugged in to a 14-50 receptacle fed by 240 volts, but it will not work if the receptacle is fed by 208 volts. Most utilization equipment with 14-50 plug will function OK when plugged in to a receptacle fed by 208 volts.

You just jogged my memory. I think the buyer had the option to choose either 12A or 16A on L2 for that first version of the EVSE Upgrade, or it was when I ordered.
It doesn’t seem like it was that long ago but how soon I forget! :roll:

I believe the following PDF of the 2017 NEC is allowed/OK to use (since it is NOT the current 2020 edition, and my understanding is old versions lose their full copyright protection once a new version is published): https://www.tooltexas.org/wp-content/up ... Code-2.pdf

For most of its EVSE rules, see Article 625 (Electric Vehicle Charging System).

Does anyone have the PDF that describes how to change the charging current on a EVSE Upgrade model? I have the newer Panasonic made charger that was upgraded by EVSE Upgrade, but I don't have the manual anymore. I want to be able to reduce my charging current on 120V, so that I can charge from my solar inverter. I'm looking for this document: Programming Guide for Gen2: (2013+)
http://evseupgrade.com/evse-programming-g2.pdf
I know it was something about shorting two pins with a paperclip and then adjusting the charging current with the release button.

Thanks
Christian

First version was 12 amps only. I had one but gave it away. I have the 24 amp version now. As far as adjusting current, unplug it then use a pin or paperclip and find hole on plug. press once for each amp desired. Then plug it back in and the setting will be displayed by flashing lights once per amp selected. The flashing repeats 3 times...maybe twice?

Thanks, but I'm not clear where I put the paperclip in. I found a post from 2011 when Ingineer was designing it and he wrote:
Another "no hardware" option is to use a paperclip between the 2 small holes in the J1772, which would cycle the mode. (this would not be dangerous, as there is no voltage over 12 present)
Do I have to short between CP and PP on the J1772 plug?
It would be great if anybody has a copy of the PDF manual.

sorry too vague. On the J 1772 side, short the two small holes
