Are you sure that's what you have? In my understanding only Norway and Albania has 230V IT. The Zoe charger only supports 400 V TN when it comes to three phase, as far as I know.
Old houses in Spain had 220/125 V. I keep it to not change wires connexions, because I use phase-phase to get 230 V. If I as my utility to switch to 400 V, I may provide a neutral to each plug... It isn't worth it.

Oh, that's perfect then. It's the same way I connect my well pump and swimming pool motor.
