I get it....this is an enthusiast forum, with mostly Tesla lovers. I wish right now I could be one of you. But instead I have bought a new car that does not work as it is supposed to. And of course while they didn't tell me to f-off or pound sand literally...it feels the same to me. There is nothing wrong with the power at my office. Tesla sent an electrician twice and he said it was the car (or UMC). My electrician says it is not the power and if another device is interfering with it then it is the car's fault because everything else is UL approved. These regulations are in place just for this reason....imagine having a solar system installed in your house and when it is on the car won't charge. The PV inverter is both CE and UL approved and has passed both emissions and susceptibility testing. The car hasn't. Are you still going to blame the PV inverter? The city electrical inspector likely won't even allow me to plug in the car because it isn't UL marked...it's the law! Whoever said that since it is a vehicle it is exempt is mistaken...these are local codes and have not been altered for Tesla's or Nissan's sake. If someone has a copy of the 2014 NEC and can post an excerpt that states that vehicle charging equipment shall be exempt from UL harmonized standards, I would like to see it.
To those of you that did post some helpful suggestions, thank you. I have tried 120V charging from outlets in different parts of the building and fed from different panels all with the same result. Charge cable fault is what comes up in the car, and yes Tesla tried three other UMC's. When on the 208 outlet the voltage is around 213 until the failure. Absolutely nothing happens on the line side at this moment....no fluctuation other than the one or so volt rise when the car stops charging. Because of the physical panel and outlet layout there is little room to play with line filtering, but I will study that more. I really shouldn't need to for reasons I stated, but naturally I am the one being inconvenienced by this. If I used a J1772 charging station, wouldn't I still need to plug in the UMC?
