Obviously SAE CCS charging
Obviously SAE CCS charging protocol stations will be spares compared to Tesla supercharger stations, which have been around for several years now (and overcrowded, I might add) . However, the futrue is far brighter for CCS charge sttaions, since only Tesla uses supechargers and most automakers (all American, German and European) already use CCS and the Asian automakers will almost certainly switch to CCS from CHAdeMO. CCS protocol also has an upgrade to 350KW, which would make it the fastest - look in the not distant future for EVs that can charge to 80% in 15 minutes. This article describes perfectly my argument that you don't need 5 minute charging capability at any time, even while traveling - you simply charge when you eat/sleep. In the case where charges to 80% take half an hour, for a 250 mile battery pack, you can easily wear yourself out driving (580 miles) while charging only twice, total of two hours, (but shortly one hour). You always will have a full charge at the start of the day. Obviously charging stations are not going to be plentiful until the numbers of EVs on the road are significant - but they are ready to become so - at least 40 EV models will be pouring out of automaker factories within the next several years. And all chargers will be DC fast SAE CCS chargers.
