There simply aren't going to be enough stations of the long distance network to cover rural areas. You can go look at their chart of highways and expected station counts. Combine that with placing stations much closer together - the *average* is 66 miles apart for the long distance network.
Not true. A recent study found that you can provide good nationwide interstate charging coverage an average of 70 miles apart by using only about 400 locations in the US. I can dig up the link, if necessary.
Electrify America says in their plans that they will have about 200 locations finished at the end of the first cycle with another 90 already in development and presumably completed within another year or so after that. That means ~300 locations by the end of 2020. It also implies good coverage over about 3/4 of the country meaning that areas near Idaho/Wyoming/Montana/Dakotas etc will likely not be covered until later which is similar to what Tesla did in its early years of Supercharger coverage.
Again, there will be 2x the vehicles of just slow charging Bolts than the equivalent era of the Tesla Supercharger network. Add to it the occasional i3 or Ford Focus Electric and then the actual long distance fast charging vehicles. It's a recipe for frustration.
There have been about 20,000 Bolts delivered in the US and probably at least 10,000 of them are in California along with many other shorter-range EVs.
And yet, I just did a ~1,000 mile round-trip from SF to LA during the Thanksgiving timeframe on CA-99 in my Bolt using only CCS and never had to wait for a charger.
I think the reason is that few sub-200 mile range EVs are driven far from home and even most Bolt EVs were purchased primarily for regional driving. Meanwhile, many Tesla drivers selected their cars for the express purpose of taking them on long-distance trips.
This may change over time as more Bolt, 2018 LEAF, and other larger-battery EV drivers gain confidence in taking their cars on longer trips.
Again, the numbers... average of 5 plugs per location. That means very few 10 plug locations and that also means many 2-4 plug locations.
Electrify America has stated that their minimum number of plugs at highway corridor locations will be 4.
The best thing for CCS to do is to make CCS v2 incompatible with CCS v1 so that CCS v1 vehicles can't clog up the DC L3 charging network. If they don't do that, they will have to spend roughly 4-6x the cost of the Supercharger network just to support the same ratio of cars to plugs due to the average station spacing. Add to it the slower charging vehicles and the higher number of vehicles overall and VW needs to spend roughly $1.1 billion in order to get the equivalent end of 2014 Supercharger network experience.
That’s your speculation. Mine is different. We shall see in due time.
You earlier noted that they seem to be planning on spending a surprisingly high amount of money per-plug. I suspect this is because their sites are going to have transformers and charger pads designed and pre-conduited for easy (cheap) expansion of charging stalls as they scale up for more cars over time.
