Weather affects EV efficiency much like it affects ICE cars, but there are some marked differences. The folks over at TezLab in Brooklyn measure range using a somewhat complicated system, but since they do the hard work for you, there's no need to get into the specific details.

Let's take a quick look at what the team discovered:

Most everything the study found can be related back to temperature

it's widely known that cars are less efficient when it's cold, however, the study shows that temps over 80F also have a negative effect

Parking in a windy area can drain more range than you may think

Cold temps increase charging times
