I've got a weird FFE charging issue that seems like some sort of business building ground fault problem, and I'm wondering if anyone else has seen something similar.
There are some 110V and 208V outlets in a section of our business building where I can't get my 2013 FFE to charge. It won't charge from the 110V outlets using my factory equipped 110V charger. And it won't charge using my "Panasonic EVSE Upgrade" charger at 208V. The weird thing is that both of these chargers will work with my FFE if I plug them in at other parts of the building.
I'm guessing that my FFE is refusing to charge because it's sensitive to some type of minor ground fault. We tried to test the offending 110V outlets for a ground fault with a normal 110V ground fault tester, but it says the outlets are Ok. The voltages look Ok when measured with a meter. Our building is on a multi-phase power feed, and that's why the high voltage outlets are at 208V instead of the residential 220V level.
It just doesn't make sense that these same chargers work fine with the FFE in other parts of the building (which all come from the same big power feed to the building). Both of these chargers work fine with the FFE at home too. And, I have a different 220V, 32A charger at home that works fine. My FFE will also charge fine from various public chargers.
I'm probably one of the few people out there that is actually allowed to use his own chargers at work, so I might be alone with this problem, but I thought I might as well ask if anyone else has seen anything like this?
