Yes, the electrician who came out said the same thing. He initially said it had to be something with the Wattstation, but after the 30 minutes talking to GE on the speaker phone said it must be the car.
Your Wattstation isn't a charger, nor is the unit you reference from AV. Those are EVSEs. The unit under the hump in the back is the OBC.
I know. I used the wrong word.
At this point, I'm clearly not plugging the Wattstation back in, and my LEAF isn't going to be plugged into another Wattstation - I don't have the patience or time to deal with another failure
. The GE guy desperately wants me to plug it back in - he wants to be able to say that it wasn't their product causing the malfunction.
Just to be clear, from both Nissan and GE - this has happened across multiple manufacturers of EVSEs - as of July (so clearly not updated numbers) 11 Wattstations / LEAFS, 5 Aerovironment / LEAFs, 3 Blink / LEAFs, and 1 "unknown" / LEAF. It seems like a higher rate on the Wattstations, but I don't have numbers of LEAFs sold / what they are plugged in to each night.
The way I see it...the possibilities include
1) I got a bum LEAF - maybe there's a "batch" of bad LEAFs particularly susceptible? Are these all LEAFs of more recent manufacture and delivery? I got mine 2 months ago, it was sitting on the dealer lot since July
2) I got a bum Wattstation
3) There is something between the Wattstation and LEAF that makes failure
a higher probability than with other chargers
The fact that my "fix" didn't work really bothers me - supposedly the OBC was replaced and the software was updated. Both GE and Nissan mentioned the "electrical storm or low voltage" situations - it certainly wasn't an electrical storm in either case, and I can't begin to speak to a "low voltage" situation that's so low that it's not perceptible by any other device in my home.
Anyway, thanks for the responses. Obviously, if it happens again with a different EVSE, then it probably wasn't the Wattstation.
