Is there a technical reason that's not possible in a future update to NACS?

  It doesn't have enough wires. For power NACS has 2 wires for single phase AC or DC and a small ground wire. CCS2 has 7 wires. 5 for 3 phase power (3 phases + ground + neutral) and 2 more for DC. It a pretty mad design. If you think about it CCS2 requires every single car to lug around a 3 phase battery AC-DC converter instead of just putting it with the chargers. Doesn't make sense.

    > 3 phase battery AC-DC converter instead of just putting it with the chargers 3-phase -> DC is easier than single phase. One of the benefits of 3-phase is that power delivered is constant, so you don't need very big capacitors. That's part of the reason nobody makes a DC fast charger bigger than about 20kW.

      Yes but is 3 phase 22kW easier than 1 phase 7kW? I doubt it.

    >It doesn't have enough wires. For power NACS has 2 wires for single phase AC or DC and a small ground wire Two wires is enough for 208V phase-to-phase from a three phase power source [0]. NACS supports three phase power sources in this configuration.
