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. …

Yet you agree with it ultimately. You even assert it while attacking me for saying it.
Again, “no serious improvement” is not the same as “no improvement”. Stop treating the phrase as if it meant that.
And frankly, the Baker Electric in its day was indeed a serious competitor to Otto-cycle cars, unlike all of the modern electrics mentioned herein. New York City even had several charging stations to accommodate Bakers and other electrics.
We are so used to the improvements in fabrication of ICs and the never-ending improvement in price/performance. But basic sciences like materials, optics, and thermodynamics evolve very slowly and are all up against some hard physical and chemical limits. Solar cell efficiency has been very slowly creeping upward and is probably close to the maximum that will ever be achieved in affordable panels.
Space program?
Radioisotope Thermoelectric Generator.
An order of magnitude is a serious improvement. Quit trying to deny that.
Utterly and completely false. Only when an improvement posits a threat to a dominant technology, and encompasses not only all the advantages of that technology but more, does it become serious.
With all due respect, you appear to be obsessed. And you’re parsing my words again.
Your comment is blithering nonsense.
An order of magnitude improvement in a technology is significant. Any attempt to deny that is utter insanity.
for me it comes down to one primary issue. I can’t store or transport electricity to power my car like I can with my gasoline car. in a real emergency I can take a truck bed load of gas cans and get to safety. with electricity, if it’s down, my car is dead.
I have a friend who bought a Tesla in the fall. He’s finding this out with the onset of winter in Utah. He’s NOT happy to find that he’s needing to recharge a lot more than what the dealer told him he’d need to now that the cold weather is here. They have family in the northern part of the state. They can’t make it on a single charge during cold weather, so now they’re making a lengthy pit stop in the middle of what used to be less than 2 hours of driving.
So the laws of chemistry and physics still hold?
Who knew?
Barely got the truck started the other morning.
My 1956 Triumph TR-3 came equipped with a hand crank in the trunk. I used it a couple of times when I'd forgotten to turn the parking lights off. So why not restore this simple old-time bit of technology to modern cars?
OK; you’ve devolved back into personal attacks, which is indicative of a liberal heart.
I’m sorry you have no intent to have serious discourse on this matter. Have a nice day.
PS. I said “serious”, not “significant”. And either word has to be measured as to how much of a market share it can capture on its own merits, even though they are not synonymous.
This seems to be upsetting you and I cannot fathom why.
I’m guessing your friend has a Tesla 3, and it is a vehicle he HAS to rely on.
There are a number of Tesla Model S’ in my area. It’s a third or fourth vehicle for owners, and they don’t drive them much when it gets much below freezing.
Owners of the cheaper Tesla 3 are probably financially stressed by their purchase, and don’t have the other easy options that people who can afford the $100k+ Tesla S’ have.
Hand cranking could be viewed as another form of hotwiring, without playing with the wires (imagine a car thief hand-cranking a Mustang GT). Some people can get hurt doing it too.
The electric starter is one big reason why the Otto cycle automobile engine rapidly outstripped competing technologies, particularly steam power.
Says the guy who accused me of being "a little too overheated". Those are your words, not mine. Own them. Don't try to hide from them
which is indicative of a liberal heart.
More of your words ...
Time for you to retire from this discussion.
No, it does not.
You're embarrassing yourself at this point.
You needed to have the key and turn it on before cranking to start the car.
You are absolutely correct. He bought the most stripped down version he could get to save money and did it as a “look at me, I’m saving the planet” statement.
Ohmygosh. The New York Thruway is sure going to be fun in the future in blizzards and frigid temperatures!
