J1772 also lacks a neutral conductor. The 3rd largeish pin you see in the plug is actually a ground connector. Its longer so that its first to make last to break which is a requirement for most ground pins. I assume both J1772 and NACS use their ground conductors for neutral when in V2H mode since a ground conductor wouldn’t really do much when the car is feeding power to the home. Both plugs have 5 pins.
