Looks like those parkas Jody and myself suggested everyone invest in way back will come in handy when your "green" "environmentally friendly" electric car runs out of juice 25 miles shy of your destination at night in the middle of a snowstorm. So much for that midnight run to your favorite Sprouts for some 19.00/lb organic gmo-free grass fed lamb chops. AAA: Cold weather can cut electric car range over 40 percent. One for the ‘worse than we thought’ file. Anyone running out of power in an EV in winter due to sudden cold weather range reduction has no in-car way to keep warm while waiting for rescue. Cold temperatures can sap electric car batteries, temporarily reducing their range by more than 40 percent when interior heaters are used, a new study found. The study of five electric vehicles by AAA also found that high temperatures can cut into battery range, but not nearly as much as the cold, reports TechXplore. The range returns to normal in more comfortable temperatures. Many owners discovered the range limitations last week when much of the country was in the grips of a polar vortex. Owners of vehicles made by manufacturers including Tesla, the top-selling electric vehicle company in the U.S., complained on social media about reduced range and frozen door handles during the cold snap. “As long as drivers understand that there are limitations when operating electric vehicles in more extreme climates, they are less likely to be caught off guard by an unexpected drop in driving range,” Greg Brannon, AAA’s director of automotive engineering, said in a statement. AAA tested the BMW i3s, Chevrolet Bolt and Nissan Leaf from the 2018 model year, and the 2017 Tesla Model S 75D and Volkswagen e-Golf. All have a range of at least 100 miles per charge. They were tested on a dynamometer, which is like a treadmill, in a climate- controlled cell. The automobile club tested the cars at 20 degrees and 95 degrees, comparing the range to when they were tested at 75 degrees Farenheit, according to a report on the study. At 20 degrees, the average driving range fell by 12 percent when the car’s cabin heater was not used. When the heater was turned on, the range dropped by 41 percent, AAA said. At 95 degrees, range dropped 4 percent without use of air conditioning, and fell by 17 percent when the cabin was cooled, the study found. When the temperature tumbled to 20 degrees last week in Hickory, North Carolina, near Charlotte, Jason Hughes noticed the range fall when he drove his Tesla Model 3 on the commute from home to work. “It would easily use double the amount of power for that 15-mile trip,” said Hughes, who owns four Teslas and runs a business that refurbishes and sells salvaged Tesla parts. Full report here. Lol. And without extensive government subsidies which only favor the rich that drive these lithium laden pieces of shit there would be no electric cars driving around to begin with. |

Plus as one salient commenter pointed out at original link, test those cars out after sitting in a cold garage for 12 hours. I bet the batteries lose a lot more than 40%. The solution in cold weather is to dress appropriately. Or just wait for the car to catch fire. Maybe the government will do a cold weather gear subsidy. In Australia none of this is a problem because the wind supplied electricity market has a tendency to go dead all the time so recharging the batteries is no issue at all, you just don't |
