Testing by AAA has found that how far an electric vehicle can travel on one charge varies widely depending on the weather. Frigid temperatures can reduce that distance by 57%.
The research is important to the Automobile Club of Southern California because it maintains mobile recharging trucks for people who misjudge how far they can go in their electric car.

Solar panels keep ‘em charged ya know.
Well, I'll give them the benefit of the doubt. It's not as if AAA could have figured out that they get more calls in the winter for cars with dead batteries that won't start than they do in the summer.
Also they apparently used a low temperature of 20F. I suspect -20F would drop performance a good deal farther.
Back a year or so ago I tried to do some research on cold weather performance of battery-powered cars. My concern was based on personal experience using various battery-operated equipment in cold weather. Sometimes -30. Lots of batteries or equipment won’t operate at all in cold enough weather. Apparently voltage produced goes down. In others performance drops way off and in all battery life goes WAY down.
Surprisingly difficult to find into on electric cars in cold weather, though. Apparently most info is posted by proponents and they don’t want to post anything negative.
“Global warming” will fix that. Problem solved. :)
The Volt has a gasoline engine. It is the drivers of pure electric vehicles that need to worry.
LOL. Plutonium ones, specifically, radioisotope thermoelectric generators.
As I’ve said before my wife was at GM I know in the case of that rolling turd The Volt, Obama’s goons forced it out the door years before it was ready. All the specs are bogus. The range was figured with no lights, no heat, no air, no rain or snow. A fraud just like every thing else that touches Obummer.
Nothing is too good for The Planet!
“Regenerative braking” is what I hear bandied about to increase range.
Makes me laugh.
Yet Elon Musk is on the cover of New York based business publications as some kind of saint.
But they don’t celebrate the guys who are doubling our gas/oil output and saving the world from a depression.
The ROI on that probably isn’t worth it, but it works.
Instead of using friction breaking exclusively, those cars use the drag of a generator to assist in slowing the car.
Yeah, it recharges the battery from the brakes, but for all the mechanisms involved, your “cost per joule” has to be prohibitive.
You’ve got that right! Heh!
Very prohibitive.
Any constant magnetic field would add drag that the motors have to overcome.
Which costs more power.
From an old "worst car ever" list, one of the touted pluses of the Yugo was a heated rear window to keep your hands warm while you push it.
I believe the heated rear window is an accessory.
+1 for the Yugo over electrics.
Duh.
Solar panels keep ‘em charged ya know.
only if the snow is cleared off and don’t park in the shade
And they just figured this out?
I wonder how long it takes a recharging trucks to recharge a battery?
