When I use my charger chord on a 14-40 plug here at work, the car charges for about 20 minutes, then fails. It fails when the AC comes on for the second time. I forgot to copy the error messages displayed, and as today is a hot day the AC is running continuously and it is actually charging. When it does fail I got to unplug and reconnect it from both the car and the wall to get it to start again. No need to flip a breaker or push a reset button. Dropping the charge current a bit did not help.
Charging off of 110 (What I normally do) or a 10-30 plug has never failed. We tried my chord at the Tesla shop and could not reproduce the issue, but the test was not done on my car or with the plug here at work. Also for some reason the errors were not logged.
Anyone have any idea whats going on?
