Some EVs are being designed as direct replacements for petroleum
powered vehicles (e.g., Nissan Leaf), others are not. As for batteries
and temperature, both the Chevy Volt and the Ford Transit Connect have
cooling and heating systems to keep the batteries at the optimum
temperature. I don't know about the Leaf, but I expect it does as well.
As for batteries never replacing a gas tank, all I can say is that
never is a very long time. There are two things to consider: 1) The cost
of petroleum as political, economic, and supply factors make it rise
and, 2) Improving technology.

It will be very interesting to see sales reports on the Volt and the
Leaf a few months from now. The Transit Connect doesn't count, however,
as the fools in Ford's marketing department decided to put a $60,000
price tag on it. The gas version of the Transit Connect sells for
$24,000, so it doesn't take a genius to calculate that the added value
from gas savings won't come close to bridging the price difference.

Agreed. Marketing always beats technology.

I doubt that anyone is working on that or that anyone ever will. You
neglected to factor in an important human element: Car buyers are not
rational. They want a car that will do jackrabbit starts and will go
150 kmph. Even I like a car that feels like it has some soup under the
hood, in spite of the fact that I know how unnecessary it is.

Another failure to consider human factors here. We value our
independence. I want a vehicle that will take me out into the woods so
I can kill cute furry animals. (OK, maybe not.) But I definitely want a
vehicle that I can use to bring home a dozen sheets of plywood from
Home Depot, and I want to do it on my schedule. The winning
transportation system will be one that maximizes user convenience. Not
that alternatives cannot be used for some transportation needs, but they
will not be the dominant system. Case in point: I carry a monthly
all-zone Trimet pass in my pocket, but I use it for only about a
quarter of my trips. If the Ford Transit Connect didn't have an absurd
price tag I would buy one, but I'd still need to rent a vehicle or use
public transportation for long trips.

I don't recall ever saying that we could replace all our petroleum
based vehicles with electric vehicles. Not only would it take a long
time, but until better and cheaper batteries are developed we need our
current vehicles for long trips.
Actually, we really don't need new technology to make electric cars
that can go a long distance. We just need cheaper batteries so we can
put two or three times the capacity into cars like the Leaf and Focus
electric without raising the cost to unmarketable levels.
