On the first working day after the New Year's Day holiday, did you also start to think about going home for the New Year?
In the Spring Festival self-driving homecoming crowd in 2022, electric vehicle owners began to receive attention.
In the past year, sales of new energy vehicles have exploded. According to the data of the Association, the cumulative wholesale sales of the domestic new energy vehicle market from January to November 2021 reached 2.807 million units, up 190% year-on-year. More and more electric vehicles will embark on the road to return home during the Spring Festival.
Not long ago, the temperature in Beijing plummeted below -10 °, and the discount on the battery life of new energy vehicles has once again become a hot topic of discussion among various car owners. Nowadays, although the mileage of electric vehicles has been greatly improved compared with before, and the low temperature performance of electric vehicles has also improved, when the temperature drops below -10 °, the battery is still "unaffordable", and the battery life is still a common phenomenon of 6-8 discount.
Recently, the "Winter New Energy Vehicle User Survey Report" (hereinafter referred to as the "Report") released by the Car Emperor shows that many electric vehicles have a mileage that is directly "frozen" by 30% to 50% in the environment of -15 ° ~ -20 °.
Zhang Hong, secretary general of the New Energy Vehicle Branch of the China Automobile Circulation Association, said that the lower the temperature, the more viscous the electrolyte will be, which will greatly reduce the activity of the battery, which will cause a significant attenuation of the usable capacity of the battery, which is a natural phenomenon.
In addition, in extremely cold weather, the battery in the car will bring about the problem of reducing the supply of driving energy because it wants to heat the car, so that the mileage of new energy vehicles in winter is generally shortened.
At the same time, the impact of low temperature on winter cars is not only battery life, but also charging. In the winter test of Chedi, the testers calculated the time for the vehicle to charge from 30% to 80% of the electricity in the low temperature environment, and concluded that the low temperature charging time of the new energy vehicles under test increased by an average of 70%.
Recently, The Emperor of Understanding Cars has carried out a winter test project for new energy models at the Hulunbuir Winter Automobile Test Site of China Automobile Center at -15 ° ~ -20 °. This article selects ten models for detailed instructions, and more test results can be found in the picture at the end of the article.
Uniform test standards were used for the vehicles in this test. (Note: The following test is a harsh environment of minus 15-20 °C)
Before the test, the vehicle is fully charged and left in the garage overnight, and the highway conditions, urban conditions and comprehensive road conditions are completed in turn.
During the test, the driving mode of the vehicle is uniformly set to the most economical driving mode and the kinetic energy recovery is adjusted to the maximum, the vehicle load is 1 driver + 1 passenger, the tire is the recommended tire pressure, and the air conditioning temperature is set to 24 degrees automatically, until when the vehicle's electricity is 0%, the total mileage is recorded.

On the whole, the Model Y's battery life estimate is accurate, and there is no sudden power loss.
In terms of low temperature charging, the measured Model Y will prompt the battery to be heated at the beginning of charging, the charging power is low, and then the power will gradually rise, the maximum power reaches more than 90kW, the power is charged from 30% to 80%, it takes 37 minutes, and the impact of the low temperature environment on the charging experience is relatively small.
Volkswagen ID.4X
Official endurance: 520KM
Measured endurance: 269KM
Winter endurance attainment rate: 51.73%
Volkswagen ID.4X in this winter test endurance test, a total of 7 hours and 10 minutes, the power returned to zero, the comprehensive cruising range of 269KM. In the test, when the endurance is less than 60KM, the vehicle is reminded to charge, the vehicle can only drive at low speed when the power returns to zero, the air conditioner is no longer heated, and the lighting and assistance system are normal. The Volkswagen ID.4X did not experience a sudden power loss in the cold winter environment.
Volkswagen ID.4X uses a ternary lithium battery in the Ningde era, which can achieve 555KM pure electric endurance in a fully charged ambient environment. According to official information, volkswagen ID.4X uses 380V fast-charging DC charging in a normal temperature environment, and it takes about 40 minutes for the power to be charged from 0-80%, and about 30% to 80% to 30 minutes. However, in the low temperature environment, it takes 56 minutes to charge from 30%-80%, and the charging speed is significant compared with the ideal environmental impact.
Red Flag E-HS9
Official endurance: 460KM
Measured endurance: 219.2KM
Winter endurance attainment rate: 47.65%
In the low temperature endurance test, the Hongqi E-HS9 chose a long endurance mode, driving on high speed, urban and comprehensive road conditions, a total of 6 hours and 15 minutes, and the power ran out after a low temperature range of 219 kilometers. During the period, when the range remains 50 kilometers, the vehicle prompts charging; after the power is returned to zero, the Hongqi E-HS9 quickly loses power and cannot continue to drive, and the air conditioner cannot continue to heat, but the lighting assist system works normally.
On the whole, the endurance achievement rate of Hongqi E-HS9 in the winter low temperature environment is in the middle of the pure electric model. Considering the large size of the body, it is normal to drag down the endurance performance slightly. Hongqi E-HS9 vehicle power estimation is accurate, there is no sudden power loss and other abnormal situations.
Euler good cat
Official endurance: 401KM
Measured endurance: 195.5KM
Winter endurance attainment rate: 48.75%
The official 401KM Euler Good Cat has an actual cruising range of 195.5KM under low temperature conditions. When the battery life of Euler good cat is less than 100KM, it will prompt the need to charge, when the power is less than 50%, the heating effect of the air conditioner gradually weakens, and the power begins to weaken, and the power is zero Euler good cat can still keep driving, but it can only drive at low speed.
At the beginning of the charge, the power of the Euler good cat is low, and the power returns to normal after the battery temperature gradually heats up. It shows that Euler's good cats have been greatly affected by low temperatures, and the charging time has increased by 54 minutes compared with the official data, which is not so satisfactory.
The following is the detailed data of all test vehicles:
