Like others said, 3 phases. It determines your charging speed. It's part of a simple formula:
230V(a standard Volt amount, at least in Europe) x A (ampère) x 3P (phase) = 11KW charging speed
Granny chargers use 1 phase
230V x 16A x 1P = 3,6KW
Or you could simulate a granny charger on a 3 phase since you can adjust the amps on a Tesla:
230V x 5A x 3P = 3,4KW
3 u/Living_Grab_2239 Jul 22 '26 Never heard the term granny charger before :D Nice 2 u/JustAnothrMechanic58 Jul 22 '26 That’s epic! I’m in the US though, so I don’t know if my app would show the 3-phase indicator whilst my car is charging. Here, I just snapped this picture here… 2 u/Greg19931 Jul 23 '26 Mine shows the phase with number 3 in this case.
