Lets take a quick and dirty look at the economics of battery size, vs. charge point economics.
For a self-sustaining market driven system, you probably need about 1 DC charge point for each 100 BEV vehicles. This is because most BEV drivers will do most of their charging at home, where it is most convenient, and undoubtedly far cheaper.
But in order to get the geographic distribution to cover major highways, you need an absolute number of DC charge locations, say 5,000 to cover the 48 contiguous states.
So an American DC charge network needs a significant minimum number of vehicles on the road to support it, 500,000 using the examples above.
Is it surprising that the manufactures planning to build only a few thousand BEVs a year, have little interest in the public fast charging infrastructure, and instead have a "lets just put more batteries in the damn thing" engineering approach to BEV range?
But I am also disappointed in The mass market BEV companies. Nissan and Mitsubishi, who seem to only want to build out the DC infrastructure as fast as they need to, in order to sell their current planned output.
These companies are a generation ahead, in BEV design and production, of those manufactures who simply pick the cheapest ICEV glider they can find, and convert a few thousand to BEVs, for PR or regulatory (CARB) purposes.
IMO, Nissan (and Mitsubishi) should be gearing up now to have a full range of BEVs in production ASAP. And IF there is a DC charge network available in 5 years, they will be able to sell every BEV sedan, hatchback, crossover/wagon, and sports car, they can turn out.
