Domestic car manufacturing is weak, what does it have to do with our land tanks? - Chapter 62
The tensile strength of T300 carbon fiber is 3.53Gpa.
The tensile strength of T700 carbon fiber reaches 4.90Gpa, which is 38.8% higher than that of T300, and the elongation at break of T700 has increased by 40%, and the bulk density has increased by 2.27%.
T1000 carbon fiber is even more exaggerated, with a tensile strength 1.5 times higher than that of T700 carbon fiber. It has reached an appalling level in terms of craftsmanship and performance, and is definitely the strongest carbon fiber material on the planet.
It is said that a T1000-grade carbon fiber about the thickness of a chopstick can pull two C919 domestically produced large aircraft.
Lu Yan breathed in almost the entire process and learned about the basic parameters of T1000 carbon fiber.
It can only be said that it is worthy of being a product of the system.
If this is used to build a supercar…
Other so-called top supercars that promote full-car carbon fiber all day long and achieve industrial extreme lightweighting will probably be turned into slag in seconds.
Lu Yan’s heart began to get uneasy.
No hurry…
Let’s see what else can be drawn first.
“System, draw again.”
Lu Yan thought to himself.
“Ding! Congratulations to the host for obtaining the super carbon fiber rotor high-speed motor manufacturing technology and complete production line equipment.”
Lu Yan was surprised.
Super carbon fiber rotor high-speed motor?
From the name, it seems to be related to T1000 carbon fiber?
“Congratulations to the host for obtaining solid-state ion battery manufacturing technology and complete production line equipment.”
First the motor, then the battery? Lu Yan was a little surprised by the result of this lottery. The technologies drawn by the system are all related to the car manufacturing industry. Although the technologies produced may be a little bit outrageous. But it must be said that these technologies are absolutely top-notch when used to build cars!!
“Is this going to thoroughly implement the new energy route? ?”
Lu Yan said to himself.
He thought he might win the top engine and gearbox technology, but he didn’t expect that he would get the motor and battery technology.
However, judging from the current development of the automobile industry, new energy is indeed the mainstream trend.
The trend led by Tesla and BYD.
Pure electric vehicles are blooming all over the world.
Cheap travel costs, strong power, and more intelligent…
But there is only one problem that is difficult to solve, that is, the problem of battery life and charging.
Even with Tesla’s world-leading electronic control and battery technology, the actual battery life of a car is only four or five hundred kilometers, and the density of charging stations is not as dense as that of gas stations. If you can’t find a charging pile, then the pure electric car is likely to face the risk of breaking down.
And lithium iron phosphate batteries and ternary lithium battery packs face the same problem, that is, poor cold resistance.
If it is in a cold winter, the battery life will even be reduced by 30% to 40% on this basis.
Can the solid-state ion battery technology produced by the system solve this problem? ?
【Solid-state ion battery: extremely high energy density, ultra-high safety, ultra-high cycle life, and extreme heat and cold resistance]
This is the system’s description of”solid-state ion battery”.
However, when Lu Yan saw its”676Wh/kg” energy density, he was stunned!!
“Damn, this energy density……”
You know, the strongest ternary lithium battery pack on the market now has an energy density of only”266Wh/kg”, and the actual range that can be achieved is only 500 kilometers.
The energy density of solid-state ion batteries is 2.5 times that of solid-state ion batteries.
Wouldn’t it be easy to achieve an actual range of up to 1,200 kilometers?
In this way, the range problem of pure electric vehicles is completely solved.
This is really awesome!!
Lu Yan looked at the description of the”super carbon fiber rotor high-speed motor” again.
Since the parameters of the”solid-state ion battery” are so outrageous, the”super carbon fiber rotor high-speed motor” may also give him some surprises.
To be honest.
Lu Yan himself did not conduct in-depth research on the research and development of motor and electronic control type technologies.
After all, Hongqi was a fuel vehicle company before, and it had accumulated the technology of fuel vehicles.
After deciding to try the new energy route, the motor and electronic control technology were actually purchased directly from the supply chain, which is also due to the current developed supply chain of China’s industry, otherwise there would be no place to buy. However,
Lu Yan still has a certain understanding of some basic parameters of automotive-grade industrial motors.
For example, the maximum speed of their previous”permanent magnet synchronous motor” was only 15,000 rpm.
However, the motor of Tesla’s flagship car can reach a maximum speed of 25,000 rpm.
Not only that.
When the speed is more than twice as fast, the volume is only half the size of their motor.
This is a technical crush.
The higher the speed of the industrial motor, the greater the torque ratio and power generated. However, once it exceeds 20,000 rpm, the extremely high internal temperature and the instability caused by the ultra-high speed will cause the rotor to demagnetize, and in severe cases it will directly burn out.
Therefore, how to keep the rotor stable under high-speed operation and not demagnetize at high temperatures is a century-old problem.
It requires a leapfrog technological breakthrough and an ingenious manufacturing process.
But Lu Yan’s eyes widened immediately!!
Because he saw a line of parameters in the description under”Super Carbon Fiber High-Speed Motor”.
“Maximum speed is 40,000 rpm?!!”
“Oh my god!”
If this is installed on a car, how much torque can it produce instantly?
Lu Yan dare not imagine.
Half an hour later. (To read exciting novels, go to Faloo Novel Network!)
Hongqi Conference Hall
“Mr. Lu, are you calling us for something?”
Yang Xudong, the head of the R&D department, came in with several core engineers.
They had received a notification from Lu Yan.
Lu Yan nodded and motioned for them to sit down.[]
“I have decided to start a new car development project, so I will talk to your R&D department first.”
What?
You are going to develop a new car model again?
Yang Xudong was immediately excited when he heard this.
In fact, there is already such a voice in the company.
“You mean, are you going to transfer the technology of Hongqi S9 to build a high-volume model that connects the upper and lower levels? In this way, with the current popularity and the support of top-level technology, it will definitely sell like hot cakes!!”
For the commercialization route, this is a very common trick.
For example, the technology, configuration, and even the design language of Mercedes-Benz’s C-Class, E-Class, and S-Class are all transferred from the high-end.
They even thought of the name of the new car.
Calling it”Hongqi S6″ or”Hongqi S5″ is perfect and reasonable.
But Lu Yan shook his head.
“No, it is too late to manufacture low-end and mid-range mass-produced models. Our goal this time is very clear. I want to build a pure electric supercar as another signature model under our Hongqi brand.”
In fact.
In this world, the original intention of the birth of the car is to pursue the ultimate speed and the strongest maneuverability.
SUV is like a product of compromise and comfort.
Of course.
It is an indisputable fact that high-end SUVs are in high volume, and the more they sell, the more popular they are.
But every year, those giant car companies spend sky-high advertising fees and huge sums of money to maintain their fleets, ultimately to make their own supercars achieve higher lap times and more exposure.
They will not use SUVs for publicity.
Even the most advanced 370 technical attempts are the same.
This is due to the image elements of the supercar itself and the absolutely orthodox model positioning.
It can be said that a car company that does not have its own supercar, no matter how successful it is, cannot be called a legendary car company.
“What?”
“Supercar… and pure electric? ?”
Yang Xudong almost bit his tongue.
He suspected that he had heard wrongly.
Their Hongqi’s technical accumulation in this area is almost zero.
Of course.
In this world, especially in China, a system with a complete industrial chain, it is not impossible to build an assembled supercar if you insist on spending money.
But what’s the point of doing that?
Is the boss really inflated?
But Lu Yan then threw out a technical drawing, which completely dispelled his doubts.
“Here are some new technologies. Please study them first.……”
“I think it is still a bit advantageous for us to build supercars at Hongqi.”
Lu Yan smiled at them.
Yang Xudong immediately took the blueprint and scanned it rapidly.
Soon, his eyes were fixed on the blueprint, and the fingers holding the blueprint began to exert force unconsciously and trembled…
His mouth was completely open!
It was as if something had completely shocked him.
“Boss, what’s wrong with you? ?”
Several other R&D engineers were also curious.
They had never seen their boss lose his composure like this.
They followed him and soon, they were also in a state of”shock for 10,000 years”!
They were roaring in their hearts!
They were crazy.
Nima…
This is more than just a little advantage?
If all the above technologies can be realized, it will subvert the entire supercar industry and completely rewrite the history of world car manufacturing!!.
