The hard wired Wall Connector does not use a neutral conductor. The 6-50 seems to be all you need.

Interesting-- that must have just appeared again this month. People have been asking for it ever since it was discontinued.
Well nobody's been wiring up 2 phase EVSE's for 50 years so that's moot. These days, it's really like 110 and 220, or 107 and 203 if you live in California and charge during peak hours.
Losses are presumably fairly close between these two so I'd expect the 5-20 to be 16/12 = 1.33x faster than 5-15.They're 12 and 16 amps instead of 15 and 20 because of the rule requiring de-rating to 80% for continuous draw.
- NEMA 5-15 (120 V at 12 A): 1,440 W = 4~5 mph indicated, 4 mph actual
- NEMA 5-20 (120 V at 16 A): 1,920 W = 6~7 mph indicated, 6 mph actual
No, it was documented here several years ago with the Model S that 16A charging is 42% faster than 12A, because once the overhead of charging is covered, all additional amps go to the battery. Model 3 should be similar.Losses are presumably fairly close between these two so I'd expect the 5-20 to be 16/12 = 1.33x faster than 5-15.
There must be some truth to what you say since certainly some of the losses are a fixed amount per time but the ~ 10 - 12% losses we see at 7 kW (240v * 32A) charging implies a substantial loss component that is a fraction of the charge rate. I don't think it is explained by i^2 lossesNo, it was documented here several years ago with the Model S that 16A charging is 42% faster than 12A, because once the overhead of charging is covered, all additional amps go to the battery.

FYIAwesome. I could probably get away with a paltry 2 mph. Thanks!
What are the volt and amp values you see when charging and only getting 2 mph?So if I get only 2 miles per hour, is there an issue with my outlet?

Do you get that on consistent basis? If you are sitting in the car with air running, then most of the power will go to HVAC. See what you gain over a 10-hour charge period. Is it 20 miles? 60 miles? This would be a more accurate estimate.
