To clarify: 3-phase power is irrelevant when it comes to CCS. The point of the Combined Charging System is the "combined". It is the signalling pins in the upper part of the Mennekes or J1772 connector and the large DC connectors in the bottom part. For slow charging, 3-phase power is relevant (the IEC Type 2 / Mennekes connector in this case).
