AutoBeta(AutoBeta.net)02/10 Report--
For car owners who buy electric cars, battery life is the most important concern, especially for electric car owners in the north, it is necessary to turn on heating in the car, and many electric car owners are concerned about how long they can run if they drive a heated car. After all, it is troublesome to find charging piles in China.
The American Automobile Association (AAA) recently tested the range of BMW i3s, Chevrolet Bolt EV, Nissan Leaf, Tesla Model S and Volkswagen Golf Electric version with warm air system.
The AAA tests under two conditions, the first being tested with a heating system, in which case the mileage of the tested vehicle has dropped by an average of 41%, meaning that the range of the Chevrolet Bolt has been reduced to 140km (225km).
The second condition is to test whether outdoor temperature has a negative effect on the range of pure electric vehicles without heating system. The results show that at minus 6.67 degrees Celsius, just starting the electric car will lose 12% of the mileage. In the case of the Chevrolet Bolt, mileage will be reduced from 238km (383km) to 209km (336km).
The test results are as follows:
The American Automobile Association analyzed the reasons after the test, saying that because diesel locomotives can use engine residual temperature to heat when outdoor temperatures drop, while electric vehicles can only rely on batteries for energy heating, this has led to a sharp decline in the range of electric vehicles in the winter.
Although the negative impact of low temperature on the battery life of electric vehicles has been recognized by the majority of electric car owners, from the current technology, even Tesla has been "infringed" by low temperature. Earlier, Tesla Model 3 owners complained on social media and online forums about the problems with their electric cars due to cold weather, especially the sharp reduction in battery life.
As Li Xiang said before, "No matter how power-saving the NEDC optimization is, the consumption of warm air is the same, and the cold decay of the battery is the same, especially the tragic air-cooled battery pack."
Low temperature is also one of the biggest enemies of the development of electric vehicles, electric car owners in the north must pay attention to control the time to turn on the heating system.
