I am an EE, and I do know the answers off the top of my head, except for wire size and I know where to look that up in the NEC.

I still hired an electrician to put in an outlet for my EVSE.

Therein lies a potential problem, i.e. finding a very qualified and reliable electrician. Years ago my general contractor (GC) indicated that his
electrician & team were very qualified for my new construction. After monitoring the first two days of their installation and then failing
the electrical inspection by the city, I removed all of their installation, had the GC fire the electrician, and did the electrical myself.

Just tell the electrician you need a 14-50 outlet for your RV. Big RV's plug into this.

It is likely that the electrician can install this since it is common.

I heard someplace it needs a 14-50 outlet. Not sure though....

Are you sure the supplied 2018 cable from Nissan doesn't rely on its neutral?

The reason I ask is that I had made an L6-20 (or -30) extension cord for my upgraded 2014 EVSE, and now I need to either make a new one (expensive), or make an adapter to let the 2018 EVSE plug in. But there's no neutral in my extension. If the 2018 EVSE truly doesn't care, then I can safely do this.

I may just try it, as it probably won't hurt it to not be there, it'll just error out.

But if anyone knows, I'd appreciate it!

L6-20 plugs and receptacles are only rated for 20 amperes. If I understand correctly, the new Nissan EVSE is rated 30 amperes at 208 or 240 volts (not adjustable). If the onboard charger in the 2018 is similar to the 2015, it will actually draw the full 30 amperes at 208 volts or about 27 amperes at 240 volts so your extension cord needs to be able to safely carry that much current. If your extension cord has L6-30 connections and 10 AWG copper conductors (or larger), it may be OK. Check for hot spots after the car has been charging for a while.

If you have an upgraded 2014 EVSE it would be 16A, be sure to check this, if 20A you can't use an L6-20. Also you should never make extension cords, this is the highest failure point, you should only use 10G cords with welded ends by reputable makers if you have an L6-30 and 20A unit. Screw on terminals loosen and cause hazards. As far as the 2018 unit is concerned you can't male an adapter and need to use a proper 14-50 outlet with the rated circuit. Contrary to what you read here codes vary in local areas and you should have a circuit rated for 50A to be in compliance. Ask city inspector if you need a correct answer for your area.

It would be possible to build a 277v EVSE if you could find the components. Most cars will accept 277V but power supplies and contactors stop at 240V. For example the OpenEVSE runs on 12V and 5V. The SMD units have a supply that max's out at 240V. On the DIY units I use an external power supply that also max's out at 240V but there might exist a 277V supply. As long as it feeds 12V and 5V the board is happy. The sense resistors might need to be increased in value though.

No EVSE uses the Neutral except the stock DIY conversion. They all require two L lines and a ground. The conversion uses the neutral to run the EVSE at 120V like it was designed for. It is the only exception that I know of. For sure Clipper Creek, OpenEVSE, and the JuiceBox do not use the neutral.

As far as I know, only the Tesla Model S and X (and maybe the Mercedes and RAV4 with Tesla chargers) will accept 277v. Even the new model 3 doesn't support it, much to the chagrin of a few folks who actually tried one of the handful of 277v Tesla sites.
