So I stopped by a hotel this past weekend to add about 20 miles of range so that I could make it back home. I plugged into the destination charger, the light started flashing green. And after about 20 seconds I got an error message stating that there was a problem with the charger. I disconnected and reconnected, but the charger seemed to be dead now. Is it possible that the destination charger was on a 50A circuit and since my car has dual chargers with a maximum draw of 72A, I may have blown the breaker? Maybe they neglected to set the dip switches in the charger. It's the only idea I can come up with.
