Just drove 1,000 miles on SCs and municipal chargers with no issues, also have a NEMA 14-50 charger @ home that worked great the first 3 times I've used it. Now I'm at my parents' house where I had a 14-50 installed at the outside panel. When I plug in it starts charging and in fact got about 180 miles but then randomly stopped. No messages on the screen, no nothing. Just stopped charging. Starting charging back from the app does not work. I had to pull the plug out physically, then insert again. I noticed that the voltage starts at 242 volt but drops to 234-236v as soon as amps start increasing. The car limited itself to 30A of 40A already, and keeps stopping now after just adding milage for maybe 30-60 minutes. I've just tried limiting it to 24A to see if this will at least get us charged, but really I need to be able to get 40/40A on this plug for our trips to be comfortable. Any ideas? Call power company? Electrician?
