While cold weather is especially hard on range, batteries also don’t like hot weather, said Brannon. “Much like when it’s cold, in hot weather EVs suffer some decrease in range, but not as much as in the cold.”

The AAA study found range fell 4 percent from EPA numbers at 95 degrees. But, again, that number was assuming the motorist didn’t mind sweating. Turn the climate control system down to 70 degrees, AAA found and range fell by 17 percent.

Tesla emailed a statement that disputed AAA’s findings, saying the report exaggerates the impact that cold weather has on its electric vehicles’ range. The company didn’t provide data saying how much range is lost in cold temperatures.

“Based on real-world data from our fleet, which includes millions of long trips taken by real Model S customers, we know with certainty that, even when using heating and air conditioning, the average Model S customer doesn’t experience anywhere near that decrease in range at 20 degrees Fahrenheit,” the company said in a statement. “And the decrease in range at 95 degrees Fahrenheit is roughly 1 percent.”

One thing that EVs and conventional vehicles have in common is that energy efficiency — whether measured by range or miles per gallon — can be affected by a variety of factors. These can include your driving style, as well as the terrain.

Do a lot of hill climbing and you’re going to use energy faster. EVs, however, are especially sensitive to any accessory drawing power, whether the car’s climate control or even headlights, meaning that driving at night, whatever the weather, will hurt range.
