In 2022, pure electric vehicles can be described as a bad start, and two things will be ushered in as soon as they come up, such as premium increases and subsidy cuts.
In terms of premiums, the overall increase in new energy is about 10%, subsidies, according to the content jointly released by the four ministries and commissions at the beginning of the year, the subsidy standard for new energy vehicles in 2022 will decline by 30% on the basis of 2021, and the decline in subsidies has caused many car companies to open a small price increase.
For prospective owners who want to choose pure electric vehicle models this year, if you are not very determined pure electric pie, then it may indeed take more reasons to convince yourself to choose pure electric vehicles.
In fact, there are many advantages to choosing a pure electric vehicle, such as experiencing fresher intelligent results, enjoying a more advanced concept of car life, and more economical car costs.
However, although pure electric vehicles belong to early purchase and early enjoyment, they do have some more troubles than fuel vehicles, such as charging problems, late retention rates, and a "maintenance cost" that is easier to ignore.
We Predict, a professional data company, has found that the current maintenance cost of electric vehicles will be 1.6-2.3 times that of fuel vehicles through the service and maintenance of about 19 million cars from 2016 to 2021.
So is it really more expensive to repair pure electric vehicles? What is the reason for your price?
In general, models with low maintenance costs usually have a feature first of all, that is, the amount of ownership is relatively large, because the larger the ownership, the easier it is to have cheap sub-factory parts to replace in the market.
However, for pure electric models, the gap between the market ownership of most pure electric vehicles and the market ownership of fuel models of the same level is not something that can be made up in the short term.
But this is not the main reason why the maintenance cost of pure electric vehicles is expensive, pure electric vehicle models are more expensive to repair, but also in the use of more advanced technology and better body materials, such as more various sensors throughout the body, smarter and more expensive headlights and other coverings, all-aluminum body design, more luxurious suspension structure and three electric aspects and so on.
First of all, there is the all-aluminum body design.
In the world of fuel vehicles, Audi is the world's first mass production of all-aluminum body car manufacturers, from the material of aluminum density is 2.7 grams per cubic centimeter, steel is 7.9 grams per cubic centimeter, through the volume of aluminum compared to steel 2/3 lighter, very helpful for weight reduction, and the use of all-aluminum body in the body structure strength can be more than ordinary steel and steel and aluminum mixed body, more conducive to improving the passive safety of the vehicle.
On the one hand, it is to improve safety, on the other hand, to reduce weight, and weight reduction also means improved handling and reduced energy consumption.
For pure electric vehicles that are inherently demanding on energy consumption and carry a heavy battery pack on the chassis, it is simply best to use an all-aluminum body, or it is a steel and aluminum hybrid body.
However, there are many advantages of using aluminum, but the problem is that compared with steel plates, the trouble of aluminum alloys is that the elasticity is relatively small, the melting point is low, and it is difficult to set the type through traditional sheet metal, which means that once a collision accident occurs, other models only need to go to the repair shop to restore through sheet metal, and the damaged aluminum can only be replaced, and the maintenance cost will of course increase a lot.
In addition to the all-aluminum body, the one-piece die-casting body technology that is becoming popular in pure electric models today may also have some impact on the maintenance costs of pure electric vehicles.
Tesla was the first to use one-piece die-casting technology on the Model Y, directly reducing more than 70 different parts of the rear body into one, and the domestic Gaohe has just announced the official mass production of the integrated super large die-casting body behind the body.
Compared with the large number of individual parts through welding, riveting and other ways to splice into a whole, the advantages of integrated die casting technology can first of all significantly improve production efficiency, which includes reducing labor, production time, reducing raw material loss, reducing production lines and so on.

Secondly, the one-piece die-casting technology also indirectly improves safety, because compared with the body structure of a whole piece spliced by welding and riveting, it is naturally inferior to the body structure of the body itself in terms of collision strength.
However, the use of aluminum instead of traditional steel to create a body structure, the trouble of integrated die casting technology is also that the maintenance economy is poor, and once a collision occurs, it is not easy to repair and can only be replaced.
However, whether the integrated die-casting technology will eventually cause a significant increase in the maintenance cost of pure electric vehicles, in fact, there are still some doubts.
Because only from the current Tesla Model Y used on the one-piece die-cast rear body, if the place is irreparable damage, it basically means that the whole vehicle has been deformed by more than one-third, and the battery pack can basically be concluded to be affected, so it is more cost-effective to scrap it at this time than to spend sky-high maintenance.
There is also an example of this recently.
A Tesla Mdel Y owner reversed the car due to improper operation hit the corner of the car caused serious deformation in the rear, Tesla official after-sales staff gave the maintenance price of about 200,000 yuan, the owner said that the original price of the car is only 280,000 yuan.
According to relevant people, the reason why the Tesla Mdel Y maintenance cost is so high, it is likely that not only the one-piece die-cast rear body needs to be repaired and replaced, if only the body is damaged, the maintenance cost will not reach 200,000, it is more likely that after the body structure is deformed, the battery pack located in the lower part of the body is also damaged, so the maintenance quotation is so high. For the owner, at this time, the whole vehicle can directly choose to scrap, of course, is the best choice.

In addition, in addition to the all-aluminum body, integrated die-casting technology, etc., which affect the maintenance cost of pure electric vehicles, there are also various advanced equipment used on pure trams today, such as digital headlights, intelligent interactive light technology and sensors including lidar.
And these equipment are often located on the cover of the most superficial parts of pure electric vehicles, once a collision accident occurs here is the first area to be damaged, and the natural cost of maintenance will be higher than that of traditional fuel vehicles.
Finally, if you are a pure tram owner who has had a repair experience, is your car more expensive to repair than a fuel car? You can also share your thoughts in the comments section.
