Tesla exaggerated EV range so much that drivers thought cars were broken (arstechnica.com)

Tesla has consistently exaggerated the driving range of its electric vehicles, reportedly leading car owners to think something was broken when actual driving range was much lower than advertised. When these owners scheduled service appointments to fix the problem, Tesla canceled the appointments because there was no way to improve the actual distance Tesla cars could drive between charges, according to an investigation by Reuters.

After some quick reading, a big thing is that you want an EV with a cooled and heated battery if you live in areas that see snow. And if you live in a warm area you'll want a battery pack that is actively cooled, as overheating will also cause poor performance, and can become damaged if they get hot enough.

According to a South Korean fine Tesla was given, their cars can apparently drop in range by about 50% if the temperature is around -15C(5F), compared to 20C(68F). With many other EVs also dropping by up to 40% because of battery temperature.

Valid, this should be tackled. Does the battery heating help?

Battery heating makes an enormous difference. I live in Ontario and generally average about -15 to -20 during the winter. Bought a Hyundai Kona EV in 2020 and it's been great. Actual range in summer is about 450km cuz I drive like an old man, and it drops to about 350km with my high traction winter tires, battery heating, and cabin heating.

The Kona also won for the best actual range during winter a few years ago
