always full? that sounds a little hard to believe. like 24/7/365 full or just once in awhile?
The CCS adapters so far have been...hot, to say the least. no thanks using something that fire-y on my Tesla.
Chademo (using the Tesla approved adapter) is woefully slow and i've been down that road for "fast" charging (2014 Leaf). not even close to reliable to count on the few Chademo outlets.
Yes, the Supercharger network currently isn't absolutely perfect. and the EA network even further from perfect. fast charging will get there. There's no way I'd even consider other than a Tesla for long distance EV travel. But i don't drive I-26 either, haha. My "out west" Superchargers are filling out nicely. Too slow a roll-out but it IS happening. Sometimes 12-20 stalls at a time! Most 250kW chargers are installed 8 at a time since more thruput (cars charge for 15 min and go) is expected as more Teslas get on the EV road trip.
It's all good. my opinion. YOMV (your opinion may vary)
I know what you mean on slower "fast" charging. My wife refuses to take our Bolt on this trip because it adds too much time to the trip (almost an hour) "fast" charging at 55 KW.
Based on looking at maps of other places, it looks like the Supercharger network beats the combined other networks in terms of locations in 9 out of 10 places and in terms of reliability probably more like 19 out of 20 times. It just seems like I-26 might currently be that 1 out of 10.
