Tesla says that a new AAA study on the range of electric vehicles (EVs) in icy or hot weather has shown inconsistent results with the Tesla drivers' experience and that the decline of this range in icy weather is far from being "close" to the 41% decrease AAA felt.
A new study by AAA has shown that at temperatures of 20 degrees Fahrenheit, badociated with the use of a heating, ventilation, and air conditioning (HVAC) system to heat up the heat, it is not necessary to use heat. Inside the vehicle, the average autonomy has been reduced by 41%, specified AAA. Thursday. This basically means that for 100 miles of combined urban / highway driving, the range at 20 degrees Fahrenheit would be reduced to 59 miles.
As part of its research, AAA has tested five electric vehicles: BMW i3 2018, Chevrolet Bolt 2018, Nissan Leaf 2018, 2017 Tesla Model S and 2017 Volkswagen e-Golf.
If drivers do not use the HVAC system, the estimated driving distance for electric vehicles is "moderately affected by hot and cold temperatures" compared to the temperature range established during tests conducted at 75 degrees Fahrenheit, declared AAA. In the absence of HVAC, the outside temperature of 20 degrees Fahrenheit has reduced driving autonomy by 12%, while at 95 degrees Fahrenheit, driving range is reduced of 4%.
The use of HVAC, however, "has resulted in a considerable reduction in driving autonomy," said the AAA, noting that an outside temperature of 20 degrees Fahrenheit resulted in a 41% decrease in battery life. driving, while an outside temperature of 95 ° F decrease of -per cent.

Commenting on AAA's research, a spokesman for Tesla sent a statement to Electrek in the following terms:
"Based on our actual fleet data, which includes millions of long trips made by real Model S customers, we know for sure that even with the use of heating and cooling, the average customer can Model S has no experience similar to that of its customers. decreased range to 20 degrees Fahrenheit, and the range decrease to 95 degrees Fahrenheit is about 1%. "
Greg Brannon, AAA Director of Automotive Engineering and Industrial Relations, commented on the study: "As long as drivers understand that electric vehicles are subject to limitations in more extreme climates, they are less likely Be caught off guard by unforeseen circumstances. lower driving range.
