>If charging time is linear Three phase 16-25A outlets are available (common in buildings/houses) in Europe (230V each phase to neutral, 400V phase to phase).

>If charging time is linear Three phase 16-25A outlets are available (common in buildings/houses) in Europe (230V each phase to neutral, 400V phase to phase). Charging Li-Ion is not a linear process at all, but at so low power (0.02C, compared to the target's battery one) it'd be, as it'd be limited by the source instead.
