I should clarify, what I'm reacting to is the gist of this story, which is suggesting that this would move us closer to the ICE model of quickly replenishing the energy store of a vehicle that could then travel hundreds of miles on that energy store. Judged by that standard, EVs are found wanting, and I think that will continue for some time to come.
While I appreciate Llecentaur's comments re: the way an EV would normally need to be charged, and agree with the general assessment that improved battery tech would be a very good thing indeed for all concerned, that's not exactly the issue I was trying to address.
My point was that I think people place a lot of emphasis on the portable battery side of the EV charging problem, and tend to overlook the very real obstacles to delivering lots of kWH on demand in a short time frame. Ideally, one would draw steadily from the grid and gradually build up charging capacity to slam into EVs as they pull up for their quick-fix. Practically, this would involve solving some of the same electricity storage problems that bedevil many renewable energy sources like wind and solar.
I believe that EVs have real virtues, but there are also limitations that are going to be with us for some time. For this reason, I think discussions about range and infrastructure are pretty misguided. We already have vehicles that exploit massive infrastructure to support their long-range travel - that's what oil-burning ICE is all about. EVs cannot compete with that directly, and attempts to get close give us an inaccessible gilded coach like the Tesla S.
We should instead turn this argument around and point out what EVs do so much better - run cheaply and replenish their power just about anywhere, especially and most conveniently overnight in their home garages. That makes them great for a wide range of uses revolving around local transportation. Solve a couple of problems like highway cruising (some reason we can't resurrect the bodies of the EV1 and/or gen1 Insight?) and heating (with heat pumps, kerosene heaters, and/or improved insulation), and EVs will truly fit in the garages of most household fleets.
