What everyone cares about is whether electric vehicles still have excellent stability and battery energy storage capabilities ten years later.

So we often see doubts from netizens: electric vehicles save fuel but not money. The fuel money saved is not enough to replace the primary battery . This concern is not groundless. The first batch of electric vehicle owners have already been hit by battery replacement.

What is completely different from the factory battery cost is that the cost of repairing and replacing the battery pack in the later period of the vehicle is basically 150% or even 200% of the original battery cost.

If it is equipped with a 60kWh battery pack, the original purchase cost may be around 70,000, and then the cost of replacing the battery pack later may be 100,000-140,000.

This is by no means alarmist, and the lost battery is not covered by insurance and needs to be replaced by the user. If the battery capacity drops to 90% in the future, it means that its actual mileage will be reduced by more than 10%.

Thinking about it from another angle, once the mobile phone battery capacity drops to 90%, the battery life experience will be greatly reduced. After the electric vehicle cruise collapses, it will bring huge inconvenience to the car life.

Generally speaking, the stipulation is that if the battery capacity is less than 80% during the 8-year warranty period, the battery can be replaced for free. If it exceeds 8 years and 150,000 kilometers, the battery needs to be replaced by yourself.

So let’s look at it, the standard that can be replaced for free is that the battery is less than 80% to be eligible for replacement.

This also means that there is a high probability that the 8 years of electric vehicles will be a hurdle. If the use environment is harsh, charging habits are not good, and the product technology you buy is not good enough, then the battery replacement is likely to happen later.

A recent "full warranty" released by Denza D9 shows that it can guarantee that the battery capacity will not be less than 74.5% for ten years. This has further strengthened the battery warranty scope of electric vehicles. On the one hand, it has increased the warranty to 10 years, and on the other hand, it has On the one hand, it is not less than 74.5%.

Of course, this is already very sincere, but it still means that the later battery loss will definitely cause trouble to users.

Especially today, when the battery life of electric vehicles has reached 600km or even 700km, ultra-large capacity battery packs of 80kWh or even 100kWh are often available. How long the battery life can be provided today? Once the battery capacity drops in the future, the replacement cost will be doubtful.

Of course, we do not rule out the possibility of lower battery costs in the future, but from the current point of view, the cost of battery replacement is still very high. According to past experience, the cost of battery replacement is enough to buy a second-hand electric vehicle of the same model.

Battery care and maintenance is a science. Although electric vehicles do not require regular maintenance compared to fuel vehicles, daily maintenance of the battery is very important. Regular charging, avoid high-intensity use under power feed, and avoid use at high and low temperatures. They are all a kind of protection for electric vehicle batteries.

Denza D9 is already a very good product, especially thanks to BYD, which is at the forefront of the industry in battery technology creation and manufacturing. However, the long-term decay problem of the structure and characteristics of the battery itself is irreversible.

This problem plagues all technology companies. In the past, the problem of irreversible battery decay was not taken seriously because electric vehicles did not reach consumers. In this market where the sales of new energy vehicles exceeded 5 million this year, the battery The problem of attenuation and later replacement must be taken seriously.

If the battery capacity is reduced to 75% in the future, will you still buy an electric car in the face of high replacement costs?
