During this time, the discussion on the Internet about who is colder in the North and the South has not stopped... The Southerners say that the wet cold in the South is a magical attack, a temperature inside and outside the house; the Northerners say that it is simply that you are not wearing enough... unbelief? Look at electric vehicles in the north are "unable to walk".
Whether the south is cold or the north is cold is not clear, but it is curious about how electric vehicles perform in the ice and snow of the north. So, we pulled 21 electric cars to the northeast where the temperature was only -20 °C to -30 °C to find out.
Summary of test models▼
The cold environment has always been the biggest obstacle to the promotion of electric vehicles. According to previous tests, every 10 ° C drop in temperature will aggravate the endurance of electric vehicles. Note: The Porsche Taycan did not participate in the endurance test due to incompatible charging, could not be fully charged, and the Mercedes-Benz EQS did not meet the endurance test conditions because there was no driving area pro license.
However, although the test environment is only -20 °C to -30 °C, there are still models with a relatively good measured range, and the small partner may wish to guess before clicking on the answer:
Reveal the answer▼
"How far can electric vehicles drive in winter" has always been a metaphysical proposition that plagues everyone, so in this winter laboratory, endurance testing has become a top priority.
In this test, the ratio of high/low speed driving conditions is 6:4, and the measured mileage of many models is less than 50% off under the extreme cold environment of -20 °C to -30 °C and the ratio of high-speed road sections.
Compared with the test data of the laboratory in Chongli- -10 °C to -15 °C in Hebei Province in previous winters, the achievement rate of about 68% can be seen, which shows the great influence of temperature on the endurance of electric vehicles.
At this time, there must be a small partner who asked, the above cars have "big battery" blessings, if you rank according to the actual measurement / official endurance achievement rate, it seems to be more fair. Then you may wish to guess again, this time the first place will be spent on who will be:
Of course, in everyone's daily life, it is rare to encounter such a strict and standardized car use scene. If you don't have such a high percentage of highways in your everyday car and the temperature is more friendly, the actual available battery life will be better than the 52% test average. As long as you do a good job of travel planning and frequent charging, driving electric vehicles in northern cities can also warm up the winter.
As for the low-temperature charging problem that small partners are concerned about, the actual situation seems to be far more complicated than everyone thinks. The decrease in lithium battery activity caused by low temperature not only seriously attenuates the charging efficiency, but also has a very conservative electronic control logic under the low temperature conditions of some models, resulting in the demand current always being at a low value, or even unable to charge normally.
However, from the perspective of charging tests under the two working conditions of cold car charging and hot car charging, if the 30%-80% stage of faster charging speed is used, the full discharge of the battery is reduced, which not only protects the battery but also improves the charging efficiency.
