Electric cars: Range plunges in heat and cold

Cold truth: The AAA says that EV range plummets as the mercury does, and that hot weather is no picnic either.
 Just as you were getting over concerns that an electric car might strand you by running out of charge before getting to your destination, the American Automobile Association has given you reason to worry again.

Electric vehicles (EVs) can lose nearly 60 percent of their range in cold weather and 33 percent in hot, the AAA found in a study at its California research center. 

The AAA used computer simulation to test EV batteries in stop-and-go city traffic and found that an average range of 105 miles at 75 degrees F  plummeted to 43 miles in a steady 20 degrees F and to 69 miles at 95 degrees F.

"EV drivers need to carefully monitor driving range in hot and cold weather," concluded John Nielsen, an AAA managing director.  AAA is a U.S., not-for-profit motoring organization that provides members with information, services and assistance related to driving and travel.

Given the annoying tendency of the weather to deliver extreme conditions and temperatures in the planet's ongoing moment of climate change, Nielsen's advice sounds solid.

While recent reports suggest that apprehension alleviation is coming soon with 300-mile distances on Tesla model EVs, the AAA's announcement delivers a different message: Welcome back, range anxiety.
