Hoping to increase the appeal of their battery-electric vehicles, automakers have begun rolling out an assortment of "long-range" models, such as the Tesla Model 3, Chevrolet Bolt EV, Jaguar I-Pace and Nissan Leaf Plus.

Under ideal conditions, these products can deliver more than 200 miles per charge and, in some cases, even 300. But as many owners discovered last week as winter storms slammed much of the country, cold weather conditions do not qualify as "ideal." A new AAA study finds that when the thermometer drops to 20 degrees Fahrenheit, range falls by an average of 41 percent on the five models it tested.
