PORTLAND (WGME) — Extreme weather could be hurting electric vehicle drivers in more ways than one.

AAA did a study looking into the effects of extreme cold and heat on EVs and hybrids.

They found when it’s cold outside, specifically below 20 degrees, it can affect the battery.

When it’s hot, usually above 90 degrees, the study found efficiency and fuel ranges drop, and operational costs go up.

A specialist with AAA Northern New England says this study is not about discouraging those in the market for an EV but instead helping potential buyers make an informed decision.

“Things they need to consider is the climate they’re currently in, when are they going to be exposed to those high temperatures or those very cold temperatures, and that’ll help determine what type of vehicle is best for their environment,” Suzanne Grace of AAA Northern New England said.

Another thing to keep in mind is charging.

She says the cost of charging at home instead of a public station can vary quite a bit.

According to the study, about 35 percent of surveyed adults say they’re considering buying an EV for their next vehicle.
