Trying to help you Charlie:
The broad steps DOE and industry need to take to meet these goals include aggressive, technology-specific, "stretch goals" established in consultation with stakeholders. Achieving these goals can enable the purchase cost combined with the operating cost of an all-electric vehicle with a 280-mile range to be comparable to that of an internal combustion engine vehicle of similar size after five years of ownership.

Just a little FYI...I work for a power semiconductor manufacturer whereas we are in 50% of every wind power generation unit in the world, we are in 40% of every solar generation system, and we are in over 66% of every electric fork lift...and just so you can actually relate...every single GM hybrid bus has our products in it...in fact I am responsible for that one... six, six pack IGBT units per inverter.
That all being said, unless we change the culture here in the USA, it ain't going to happen. One of my clients are in the final stages of qualifying a class 8 truck that is 100% EV, problem is...it will end up at best a city delivery as even with regen systems it is limited in range and that depends not only environment, but weight too.
We are working in R & D on stuff that will not be ready for at least ten years and probably not twenty...the big thing...we have not been able to advance the range vs regen vs time. How long does it take to put 20 gallons of gas in a car? 20 minutes max from getting off the freeway and getting back on...and then drive another 400 miles. Well...took my Tesla on a 330 mile trip...ended up being a 24 hr trip. My other car, I make it in about five hours including stopping for gas. I do not see that changing much in twenty years. Even a quick charge system might take a few hours to still get max range.
