I think I do. Boy, this is going way back into the memory banks, and I'm not having luck with searching to find the threads about it. I forget which exact years it was, maybe something like 2010 and 2011 or something? In the first couple of years of the Nissan LEAF, the little 120V charging cord it came with did not correctly comply with the J1772 specification. The timing signals were wrong somehow.
I'm not one of the real OG owners--I consider those the 2012 and 2013 people. But I was reading the forums and collecting data during that time, so I do remember a lot of that stuff that I found interesting.
I have that charger, dating from 2014 (my first EV was a leased Leaf, for 3 years), it worked just fine with my M3 SR+. Only did 30A but it worked. Eventually replaced it with Tesla wall charger because, well, 2 more amps and I had plans for a 3LR that could do 48A that hasn’t come to fruition Yet. So it must be the earlier ones.Yeah, those old Nissan EVSEs (made by Aerovironment) didn't have the negative half of the pilot signal. Most cars don't care, but some do, like Teslas. This used to cause owners problems. One of the common failures was the diode in the LEAF's charger that kept the negative half of the signal from being pulled towards GND by the car. If it was, the EVSE would assume the plug was in a puddle or something, NOT plugged into a car and refuse to energize. This would cause the car to be unable to charge at most EVSEs. However, the dealers all had these Nissan units, so the car would work when people brought it in to be fixed. The portable plug that came with the car had the same issue, so no help there. Cue a long fight to get the dealer to admit there was a problem that needed fixing.
Anyway, as I remember, most of them were hard-wired, but doing a quick image search found a smattering of them installed with a plug. If your daughter's install has a plug, you would be able to use your mobile connector with the proper adapter (probably 6-50), but I don't think it likely.
Is the that dual voltage L1/L2 120/240 volt EVSE that ships with some '18+ Leafs? If so, it can plug into NEMA 14-50 or 5-15. If using 14-50, I guess you could bring your mobile connector with a 14-50 adapter, otherwise it's 5-15, which obviously super slow.I'm visiting my daughter, and I forgot to bring my charger adapter.
She has the EVSE for charging her Leaf (shown below). However, when I use the adapter with her J1772 plug, it fails to charge, and I get a message about a failure to communicate.
Out of luck for home charging?
Thanks.

=======================================
(moderator note: Moved this post which was a separate thread created into the thread where this question was asked previously.)
There really isn't any easy way to fix it. The negative half of the pilot signal just isn't there. Even if you were willing to try modifiying the circuit inside the EVSE, as I recall, it was potted, and the EVSEUpgrade folks had a time just uncovering the components they needed to change to allow 240v operation. Your best bet is to either sell it to someone who can use it, or decide you've gotten your money's worth out of it over the ten or so years you've owned it, and replace it. You can buy similar portable EVSEs much cheaper these days.
