Cold temperatures can sap electric car batteries, temporarily reducing their range by more than 40 percent when interior heaters are used, a new study found.
The study of five electric vehicles by AAA also found that high temperatures can cut into battery range, but not nearly as much as the cold. The range returns to normal in more comfortable temperatures. […]
AAA tested the BMW i3s, Chevrolet Bolt and Nissan Leaf from the 2018 model year, and the 2017 Tesla Model S 75D and Volkswagen e-Golf. All have a range of at least 100 miles per charge. They were tested on a dynamometer, which is like a treadmill, in a climate-controlled cell. […]
At 20 degrees, the average driving range fell by 12 percent when the car’s cabin heater was not used. When the heater was turned on, the range dropped by 41 percent, AAA said.
At 95 degrees, range dropped 4 percent without use of air conditioning, and fell by 17 percent when the cabin was cooled, the study found. …

The technologically illiterate are get flim-flammed. Was this not predictable?
Seriously, anybody who has tried to start a conventional auto on a 20 degree morning knows that the battery has less energy to start the car. Also, heat & A/C are not ‘optional’ things as this article seems to imply.
Why didn't I think of that?
It’s not the engineers, it’s the buyers.
Most of them think electricity comes from the socket in the wall, and is created when you turn the switch “on”.
What problem?
What is not discussed is another bummer for ion batteries. Extreme temperatures, either hot or cold, shortens the overall life of these batteries
No poop Sherlock.
That’s not surprising at all. What is surprising is that buyers and potential buyers wouldn’t realize this and have to be told by a study. There’s only one source of stored energy in an electric vehicle. If you use it to generate heat, or cool, that’s energy you don’t have to move. Fossil fuel powered vehicles get heat almost for free. The engine produces waste heat. To heat the passenger compartment only requires a little juice for the fan and maybe a tiny amount of loss from pushing coolant through the small radiator in the heater instead of the main radiator. (Probably about equal) Running an air conditioning compressor (and the fan again) for cooling can take a noticeable chunk of energy from gas/diesel engines. (Particularly small engines) Hence the debate over when to switch from windows down (and drag) to windows up and AC.
If you drive with no heater or AC running, you don’t drain the battery. You guys are just not as creative as the Collectivists..
Single digits almost reduced our internal combustion gasoline vehicle by 100%
Barely got the truck started the other morning.
Tesla said they’re going to be pushing a software change to solve the range problem in cold weather (true).
LOL, as if the laws of physics can be changed by a few lines of code.
Keep in mind, that’s only 20F. Below zero is twice the fun!
...and then, what happens if they get stuck outdoors in a snow jam, particularly with less than half a charge? They may have the one car that lets them hold their noses up at their friends at parties, but they will EASILY be the first to freeze to death out there too.
Ya, like buying a real car to drive when the temperature is anything but 75 degrees.
“You also can only convert solar into electric, on average, about 10 hours per day in the US - it’s too dark at night. Not enough sunlight.”
Actually, without being able to track the sun, it’s closer to 5 hours of decent power production, and that’s in perfect weather. There are charts with the numbers on them, ranges from like 2 hours in Seattle to 8 hours in the desert southwest.
“I don’t know whose idea it was, but somebody suggested Trump announce he is installing solar panels all along the US border, about 40 feet in elevation order to minimize tampering. I could go for that compromise.”
That is why Telsa has them on his supercharging stations. If you add up the power production for a single station over a single day with good sunshine, you can charge about 1 car. The other 99 or so have to get their power from the dreaded ‘grid’.
Obviously most Tesla owners can’t do that math, so they really do think they’re being charged with solar power at these stations.
“I’m shocked when I find some people who think the place to store AA, AAA and 9V batteries is in the freezer!”
Others put them in the refer. The concern is self-discharge. As it is, just buy the Everready Lithium batteries (in those same above sizes) and they’ll last 20 years before self-discharging, and that’s at room temperatures. And they’ll never leak either.
(and no, I don’t have their stock, but maybe I should)
DUH!
You mean the manufacturers and the climate wackos never told you that?! How come I knew it? I don’t need AAA to tell me that.
Did you plan to use an air conditioner during the summer? Did you actually want heat in the winter?
And when the electric cars break down, what do you think powers the trucks that come to get them going again?
Only petroleum products contain enough stored energy to make their use worthwhile.
Turn your Muskmobile into a car bomb?
I thought they were already exploding... :-)
The electric car owners could pile their hemp blankets over the batteries to keep them warm at night.
Hahahahaha.
It’s two, TWO sources of detonation in ONE!
