I hope the EA stations are more reliable, the ones I looked at appeared active. This is a whole new world, estimating charge times and detours to charge stations. I travel across Florida, or did before Covid, to visit friends about 6-8 times a year; so I did some calculations.
There are independent networks like ChargePoint that can be used as an alternative (you will have to pay of course), most are level 2, but when I was mapping my long distance route across Florida, I noticed a level 3/CS charger with 6 bays at the Fort Drum plaza on the Turnpike, perfect for my projected return trip with no detour. I plan at least 15 miles of reserve range.
EA has limited locations, the two most convenient on that cross-state route were 2-18 mile detours adding about 5 to 35 minutes to the commute, not including charging. Locations will become more convenient over time, but I would guess at least a year to add to my route, possibly longer. One reason the Audi E-tron GT was a no-go is the 225 or so mile range, because the EA detour adds enough extra miles (371 round-trip with no charging station detours) that even going one way would almost deplete the battery and add at least 1 hour of charging (the rate slows considerably above 80% capacity) to a total 7 hour trip. Now the Air with the estimated 89kWh battery using 20" wheels, a/c on, and driving at an average of 55mph (city/hwy), should yield about 360 miles of range and would only need a 40 mile boost on the way back (I am planning on installing a level 2 connection at home) using the ChargePoint bay; that would take about 15 minutes at 175kW/h.
