Can't Charge Via Nissan EVSE (With Adapter)?

We'll be visiting our daughter soon. She has a Leaf and a Nissan EVSE. I thought I could charge through that (with the J1772 adapter), but she said that that didn't work with another friend's Tesla.

Anyone know why not?

Thanks,

Al

Nissan uses CHAdeMO and they may have a DC charger.

EDIT: Misread and thought you were going to a dealership to charge. In all likelihood the Nissan charging station will only allow recognized Nissan's to charge.

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.

So this kind of went like the Microsoft situation. Their products did not comply with the published specifications, but they had Windows versus Office both set up to work with the "wrong" stuff, so they seemed to work perfectly together. But with some other company's Office programs, they would have problems running in Microsoft Windows according to what the published specifications were supposed to be.

I've seen a couple of threads on this. If it's one of those Leaf power cords from the first few years with the incorrect communication, it won't work on Teslas or other cars that expect the actual J1772 communication. Nissan did get that fixed in later years so their charging cords implemented the actual J1772 spec and would work on other cars.

This is some OG godfather EV knowledge dropped here, man! Thanks for sharing!

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.

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.
