Likely not. If a Vehicle sees AC power on the connector prior to requesting power, it will fault out.
If you were to put 12V DC on the pilot then turn on PWM when the line is pulled down to 6v then turned on the AC power it would work (but not be safe without GFCI, ground monitoring, etc.)

Hi all - trying to get my head around the simple "negotiation" that takes place between EV & EVSE,
In simple terms, putting safety aside*, if you were to apply mains to the Type 2 connector AND a 50% 12v PWM to CP, plug it into the EV, would it start charging?
This way, the connector is coming in hot, with signal at CP telling car that charge is available at 30A.
(*putting safety aside for purposes of understanding only)
TIA.
