Full charge of EV detection

Hi all,

Just a “simple” question, because it is not clear.
How do you detect a full charge of EV ?

I’m not sure.
3 is charging.
Seems to be 2.
Sometimes 3 will go to 254 if the PV divert switches OFF.

I don’t find clearly in the document all the state description and the finite state machine between thems.

Thanks :-).
