I have a 2016 S90D and charge at home using 40 or 50 amp circuit. Please excuse my electrical ignorance, i can confirm specifics if asked.
Anyway, since getting the car, its consistently been charging at around 30 miles/hour. It has recently decreased to 22-24 miles/hour. This speed is true even after several hours of charging.
I haven't made any changes to the electrical system in my home and continue to use the same plugin cable the car came with from Tesla. Any ideas on why the charging speed would suddenly have dropped?
