The specs released on the Model 3 Long Range say that it will charge at 37 miles per hour on a NEMA 14-50 plug. What isn't clear to me is whether there would be any advantage in charging rate with a Wall Connector with a 90-amp circuit. Can anyone say definitively if the Model 3 will be able to charge at a higher rate than 9.6kw? A High Amperage Charger Upgrade (offered on the S and X) doesn't seem to be in the cards for the initial production of Model 3. That makes me think my Model 3 will be maxxed at 37 MPH for home charging even with a Wall Connector that has more power available.
