Chapter 1229 [Between pure electric and hybrid, of course I want both]
Fang Hong listened silently and nodded from time to time, while Qin Feng further elaborated in an orderly manner: "In addition, we also plan to engage in vertical integration of the supply chain. Xingyu Technology only focuses on some core things, such as intelligent driving systems, automotive chips, etc.
In hand, other productive things are left to the manufacturer."
Obviously, you don’t need to develop and manufacture everything yourself, just focus on the core things. Things like tires and glass that can be used in common with traditional fuel vehicles are already mature and you still have to develop them yourself.
My brain is flooded.
Fang Hong nodded again in recognition of Qin Feng's words. The idea of vertical integration is very correct. In the future, the focus of new energy vehicles will still be intelligent vehicle operating systems and vehicle-standard chips. As technology continues to iterate and advance, future
More and more chips will be used in cars, and the proportion of chip modules in the cost of the entire vehicle will continue to rise. This module will also become a huge source of profit for a car.
In addition, there is the creation of the car's intelligent driving system and platform ecosystem. A smart car can be regarded as a large smartphone, and the car is highly bound to a person's identity. What does this mean? Data is more valuable.
As long as the scale effect is achieved and quantitative changes bring qualitative changes, the profits of car manufacturing itself will not even be as good as the realization of data. In other words, smart cars themselves can be sold cheaper in the future, and Xingyu Technology's profits do not need to be directly reflected in the physical body.
, but the various data and services attached to this vehicle.
Therefore, you don’t need to be 100% self-researched and self-produced, just master some core key parts and unique skills that you won’t be able to play without it.
After a while, Fang Hong seemed to be talking to himself: "The chip is still a key link that cannot be ignored. Whether it is used for mobile phones or cars, the chip must be technologically independent and cannot rely on Europeans and Americans. Otherwise,
In the future, the sales of cars will be better, and you will be stuck or the price of chips will be set very high, and most of the profits will be taken away by foreign chip manufacturers in the chip process. That won't work."
In the future automobile industry, especially new energy vehicles, chips will still be an indispensable key link, especially the future launch of intelligent driving systems.
Fang Hong turned to ask: "What route will the car take in terms of power? Has it been finalized?"
Hearing this, Qin Feng replied: "It has been decided, and two plans will be promoted at the same time. One is pure electric drive, and the other is plug-in hybrid. The general idea is that we will promote hybrid mode north of the Qinhuai Line, and the Qinhuai Line To the south, pure electric mode is promoted. This is the result of comprehensive consideration of factors such as my country’s vast territory, differences in climate, environment, and terrain between the north and south.”
Qin Feng looked at Fang Hong and explained in detail: "Our research has found that, as far as the current battery technology level is concerned, it is still not suitable to promote pure electric vehicles in the north until more advanced technology levels are released.
The climate temperature difference is huge, and the impact of low temperature on batteries is difficult to ignore when using pure electric vehicles in the north. The impact of low temperature on lithium-ion batteries may be permanent, and its performance will not be fully restored just because the temperature returns to normal.
"
"Our technical team went to the Inner Mongolia region in the north to conduct experiments in this area. The experimental results showed that after the battery was placed in a low-temperature environment for 48 hours and then placed under a greenhouse, when charged with slow charging, the capacity will decrease.
The loss is about 3.2%, and when using fast charging, the capacity loss reaches about 6%. From this, we also came to the conclusion that in order to ensure the capacity and life of the battery, it is best not to place it in a low-temperature environment
.”
Fang Hong couldn't help but nodded: "Issues such as geography and climate do have a great impact. BYD's rise has also been advantageous at the regional level. The company's main customer groups are also in the south. On the contrary, there is no second BYD in the north.
Di, it can be seen that differences in region and climate are also key factors."
Qin Feng continued: "The impact of the battery life span is also multifaceted. There are various conditions. For example, if the battery is charged every day and discharged per unit time, if the use is regular and stable, the battery life will be longer.
Longer."
This is actually a matter of common sense, not just for batteries, but for other things as well. The same is true even for traditional fuel vehicles. One is driven frequently, while the other is driven twice and left for a long time. The former is not easy.
Bad, the latter is relatively more prone to problems. Even if you use other things once or twice and then throw them away for a long time, problems will easily occur.
Qin Feng continued: "There is also the battery usage environment. Why is it said that the north is relatively unsuitable for pure electric vehicles? The usage environment is very large. The weather in the south is hot, but this heat is caused by high humidity. The temperature is actually not much higher than in the north in summer, but
As long as winter comes, the stability in the north is very low, and the temperature difference is more extreme than in the south. For example, in the extreme weather in the Neimeng area, the temperature in summer can be higher than in the south, while in winter it can drop to minus 40 degrees Celsius. In the south,
It is impossible to drop to such a low level in winter. In this extreme low temperature environment, the battery life of pure electric vehicles will also be greatly reduced when the low temperature and electric heating are used."
"Another point is that for pure electric vehicles in the north, air conditioning and heating are also a big problem, and electric heat is needed for heating. On the contrary, the engine of traditional fuel vehicles has its own heat source, and the waste heat can be used for heating. This is true for fuel vehicles in the north.
The extremely low temperature environment in winter is an advantage over pure electric vehicles. Of course, if the heat source of traditional fuel vehicles is placed in the south when the weather is hot, it will be a huge burden."
Obviously, depending on the different usage environments, pure electric vehicles and fuel vehicles have their own advantages and disadvantages.
Generally speaking, under the current technical level, the environment in the north is not very friendly to pure electric vehicles, but it is much friendlier in the south. If pure electric vehicles are to achieve the same effect in the north as they can in the south, further technological advancement is needed
Iterative upgrades, especially battery technology.
This chapter is not over yet, please click on the next page to continue reading! Between plug-in hybrid and pure electric drive, Qin Feng chose to have them all. Both power forms have their own advantages.
We all know the advantages of pure electric drive mode. The biggest feature is environmental protection. Pure electric vehicles achieve zero emissions and zero pollution, which is of great significance for improving air quality and reducing carbon emissions. Of course, is it true zero emissions?
It depends on the final source of electricity. If the electricity is charged using renewable and clean energy, then it is truly zero emissions and zero pollution. If the electricity is generated from coal, it cannot be said to be zero emissions and zero pollution.
The plug-in hybrid mode also has many advantages. During short-distance driving in the city, you can rely on pure electric driving to achieve zero-emission, low-noise and environmentally friendly travel; during long-distance driving or when the battery is low, you can start generating electricity to replenish the battery.
Thereby extending the cruising range. In addition, the plug-in hybrid can also use the energy recovery system to recycle energy when the car is braking and coasting downhill, further improving the efficiency of energy utilization and extending the cruising range.
.
Generally speaking, the plug-in hybrid mode can be regarded as a compromise solution under the current technical conditions. If battery technology usher in revolutionary development, and super materials such as room temperature superconductors are truly available, energy transmission will
With zero loss, these problems will no longer be a problem. There is no need to dig and search to accurately calculate the amount of energy. Problems such as what is suitable for the south and not suitable for the north can be easily solved.
However, the development of technology does not happen overnight, and it also takes time. As a compromise solution, hybrid is a feasible solution at the moment.
