From ground to either hot, its 120v.
Since you have 120/208-volt service (two phases and neutral from a three-phase source) you will need to obtain an EVSE that works on 208-240 volts. Clipper Creek is a good choice. I have an HCS-50P (specify 14-50 plug when ordering) that works fine on the 120/208-volt service at my workshop garage.
I find it really hard to believe that Nissan did not design their new portable EVSE to work on the common "RV receptacle" voltage available in commercial installations in North America.
