Well said.
The Tesla won't be fast charging if you have a single phase outlet, connecting to a 4 or 5 prong; because there is no voltage difference between the pins (only L1 and ground (or L2-ground, or L3-ground).
The only way using multiple outlets would work in charging the car is:
- If the car can be configured to charge beyond the 15A a normal breaker provides on a single line, or,
- If there is a phase difference between L1 and L2.
The phase difference can only be gotten with a rated capacitor, or with an extra line.
The capacitors used in AC systems or motors of the kind, usually are fixed value, which means they're meant to run on a fixed load.
Once the Motor RPM varies chances are that the motor isn't running optimally anymore.
With a Tesla, using almost all the power your home net can support.
With single phase and a cap, there will be additional losses.
