Well, if you can't shake the license plate, you can install a charging pile. You don't need to travel long distances, and you don't care about the form of power. Buying an electric car is still a good choice.
But in fact, in the process of buying, there are still many friends who are worried about the battery, but what should I say? A battery is 70 thousand or 80 thousand, right Even if you spend 70 thousand or 80 thousand, you can still buy an electric car.
I can't stand thirst. A bottle of mineral water in the scenic spot 10 yuan, and my promotion in buy buy only cost 1 yuan. Didn't I finally buy and drink? correct
First of all, the cost of power batteries is not constant, but decreasing year by year. Now it sounds alarmist, 70 thousand or 80 thousand. When it is replaced in the future, it may not be the same price, but it will be cheaper.
20 18 UBS Group AG (UBS group ag) released a report entitled "the heart of electric vehicles". Samsung, Panasonic, LG and other well-known power battery manufacturers. The average battery cost is 150 USD/kWh.
In 2020, UBS Group AG AG Group AG and P3 Automobile jointly released a power battery disassembly analysis report.
Therefore, from 202 1 to 2022, the battery cost of most manufacturers will reach 100 USD/kw h, and then it will continue to decline. You see, the 150 just now has become 100, which is still US dollars.
The human saying is: I bought an electric car now, and then I changed it. It is definitely not as terrible as I think now. Looking back, the current battery is cheaper than the previous three years 1/3. I feel confident and don't panic.
The manufacturer has a battery quality assurance policy, which has played a certain role.
Besides, don't all electric cars now provide battery warranty? Don't worry too much about battery failure.
To put it simply: under normal circumstances, it will not break. Generally speaking, if it is broken, we don't have to pay for it. This is guaranteed. Just listen to money. Under normal circumstances, we don't need to pay for it.
Refer to the Notice of the Ministry of Finance, the Ministry of Science and Technology, the Ministry of Industry and Information Technology and the Development and Reform Commission on Financial Support Policies for the Promotion and Application of New Energy Vehicles (2065 438-06-2020).
New energy vehicle manufacturers should provide consumers with the warranty of power batteries, drive motors, motor controllers and other energy storage devices for not less than 8 years or 6.5438+0.2 million kilometers, which takes a long time.
In reality, many car companies do not have a clear statement about whether the battery attenuation is guaranteed, but it is better to have protection than nothing.
Moreover, a small number of car companies have made it clear that if the battery decays to a certain extent, it can be replaced for free.
For example, Tesla promises that the battery capacity is less than 70% for free replacement during the warranty period; Roewe and GAC Chuanqi promise that the battery capacity is less than 80% and it will be replaced for free.
Most cars travel 400,000 kilometers, and the battery capacity is above 80%.
In addition, the current power battery, even if driving 400,000 km, the battery capacity is unlikely to be less than 80%.
Jiang et al. published a paper "Cycle Life Test of Power Battery System of Electric Vehicle" in the magazine "Energy Storage Science and Technology", which said.
In the 80% deep charge-discharge cycle life test of ternary lithium battery power system, the battery capacity decays slowly before 1200 cycles. When 1200 cycles, the battery attenuation is only 14.3%.
In this case, 80% charge and discharge means that the battery is charged to 80% and then completely discharged, which is the case.
The experimental conditions are stricter than the actual working conditions. When you actually use the car, it is unlikely that you will discharge until the car stops, right? correct
Moreover, when charging, it is generally not true that the battery is fully charged to 100%. Manufacturers will "lock in" part of the capacity, just to protect the life of the battery and use it longer.
So even according to the previous rigorous experiments, after charging the car 1200 times, the battery capacity is still 85.7%.
According to the calculation of 500km battery life: 80% charge and discharge battery life is 400km, 1200 times, and the mileage is 480,000 km. Even if you drive 20 thousand kilometers a year, it will take 24 years
Moreover, the life of the popular lithium iron phosphate battery is longer than that of the ternary lithium battery.
In other words, the battery capacity will drop more slowly.
This is why some manufacturers dare to guarantee that the battery can be replaced free of charge if it is below a certain capacity during the warranty period.
But for some older electric vehicles, the original cruising range is about 200km. After attenuation, it may be similar to the distance that electric bicycles can drive. This may really affect the use.
When buying a car, to be on the safe side, it is best to estimate the cruising range of 80% of the old car to see if it can meet our actual life and travel needs. This is a more practical point.
Many people don't have to face the problem of changing batteries. Finally, judging from the cycle of changing cars, many friends don't need to consider changing batteries after buying electric cars.
J.D.Power released the owner's picture book of China (version 20 18). Nowadays, the replacement of private cars is actually very frequent. Only 1% people own cars that are older than 10.
To put it simply: there are quite a few people who can drive 10 for more than 0 years, one in a hundred, one in a hundred. What's more, the battery capacity is still above 80% after 400,000 kilometers of normal driving.
Only when the electric car is sold, its own preservation rate is relatively low, which will further lower the price because of battery attenuation.
If you want to buy an electric car, you can. Don't worry about changing the battery. Generally speaking, you can buy an electric car. Don't be scared to death because the battery is expensive and how much it costs to change it. Generally, it doesn't need to be changed, and the quality is good. Generally, it hasn't changed.
And there is really no way, there is no warranty, and it is not any other problem. Really have to change the scalp. The price at that time was not as expensive as it is now.
Moreover, major manufacturers also have battery warranty policies.
Needless to say, it is broken, and the power consumption is less than before. There may be more advanced solutions, and you don't have to spend a lot of money to solve them yourself. National policies also support this development direction, you can rest assured.
Is an electric car really more comfortable to drive than a fuel car? There are more and more electric cars on the road, which shows that people are less and less worried about changing batteries.
Aside from the battery problem, is the electric car really more comfortable, advanced and better powered than the fuel car?
If both electric vehicles and fuel vehicles operate for one year, what is the difference between the comprehensive total costs? What are the gaps between domestic electric vehicles and Tesla?
What is the status of our own brand electric vehicles in the world now? Is it better or worse?
Keywords: electric vehicles
It's very simple to know this, "spare tire says car", just reply to the keyword "electric car".
I will give you a practical dry goods every day, including text, audio and video. Just choose the version you like. Spare tire talks about the car waiting for you to play.
