Now the amperage/voltage limitation is at the charging station primarily vs. the car in the other scenario.
The vehicle's BMS does the primary control of the charging current.
You're both right. The charging station limits the charging current, but the car determines what it actually is, subject to that limit.

Most all homes are wired for two phase (~ 220V for some applications), and that provides the ability to develop the higher L2 charging power.
Nope, the wiring of most houses is single-phase, or split phase. It's confusing because there are two lines that are 180 degrees out of phase with each other. From wiki "The two 120 V AC lines are supplied to the premises from a transformer with a 240 V AC secondary winding which has a center tap connected to ground. This results in two 120 V AC line voltages which are out of phase by 180 degrees with each other. The system neutral conductor is connected to ground at the transformer center tap. 240 V AC can be obtained by connecting the load between the two 120 V AC lines."
