There's your problem. They're from Eaton.
My only personal experience w/Eaton level 2 EVSEs on my '13 Leaf (I don't have an '18) is at http://www.mynissanleaf.com/viewtopic.p ... 45#p521945
. I wouldn't be surprised if an '18 doesn't work on those 3 Eatons at Aloft hotel in Cupertino, CA.
You might want to edit your OP if all of the L2's that don't work for you are from Eaton. We have a ton of Chargepoint CT4000 series (https://www.chargepoint.com/products/commercial/ct4000/
) at my work and I've seen '18 Leafs charging on those w/no problem. I've also seen '18 Leafs charge successfully on these old Clipper Creek units at https://www.plugshare.com/location/7989
If Eaton hasn't changed their stance on non-support of their EVSEs (I tend to think it'll be unchanged), you may want to formally contact Nissan (https://www.nissanusa.com/contact-us.html
, maybe the EV Customer Support Team; NOT a dealer) and let them know. It may not do anything for now, but if enough people complain, perhaps Nissan can actually issue a fix (probably firmware update) to get them working. Make sure they open a ticket and have the call/contact in their logs.
Admittedly, the chances of a fix are remote and judging by how slowly some other fixes have been coming, it may take a LONG time, if ever.
