Chapter 241 The Importance of Safety
June 24, 2027.
Jiang Miao signed the 35th acquisition contract this year.
At present, Hailufeng Company has been officially upgraded to a group, with an astonishing number of subsidiaries reaching an astonishing 43, and 15 joint ventures and equity-owned enterprises.
Whosely-owned subsidiaries include Hero Dairy, Fengmei Takeaway, etc.
These subsidiaries cover many industries, such as aquaculture, feed, agricultural technical services, agricultural planting, deep processing of agricultural products, textiles, papermaking, sugar making, edible oil, pre-made vegetables, power generation, batteries, gas, snacks, retail, dairy products, Tourism, logistics, seedlings, catering, airship manufacturing, automobile manufacturing, testing services, charging and battery swap services, etc.
No mistake, Hailufeng Company currently has an automobile manufacturing business.
In June, after more than three months of secret negotiations, Hailufeng Company officially acquired WM Motor's Huangzhou factory and Yongjia factory, with a purchase price of 3.5 billion yuan.
Just when Goldwind Technology came to inspect new materials.
Hailufeng Company has taken over two WM Motor's automobile assembly factories for half a month. After half a month of adjustment and recovery, the factory management has begun to smooth.
However, there is definitely no production capacity, because Hailufeng Company did not ask for the brand of WM Motor, but planned to start a new business itself, and did not have the idea of becoming an OEM factory. Without orders, there is naturally no production capacity.
At present, various licenses of Hailufeng Company's automobile subsidiaries have been completed. The name of this subsidiary is: Panshi Automobile.
"Rock" symbolizes stability and indestructible, and is in line with the technical advantages of passive safety (body structure); the English "Panshi" retains Chinese pronunciation and strengthens cultural uniqueness.
This is Jiang Miao’s brand positioning for Panshi Automobile.
Why should safety be used as the brand positioning of Panshi Auto?
The reason is Jiang Miao's own ability. He can easily discover the problems of the current in-vehicle intelligent networking system, and he can easily control various smart cars.
Many people are not aware of this terrible danger.
But Jiang Miao has already noticed the huge risks.
Especially, AI technology has developed wildly in recent years, and humans are increasingly relying on AI, but the development of things often has two sides.
AI is like a double-edged sword.
With the increasing number of various smart devices, once the AI is out of control or is secretly controlled by others, the consequences are absolutely unimaginable.
If it is a smartphone, tablet, or something like that, even if an explosion occurs, as long as there is no C4 or something, it is generally not powerful and there is a great possibility of escape.
However, once a smart car loses control, the death rate in the car will be very high during high speed driving.
As for the safety guarantees of those car companies, just listen to it.
After all, car companies can lock the car's battery through remote control. Obviously, in terms of management authority, car owners are lower than car companies.
In this case, once there is a problem with the intelligent system, the owner is very likely to be unable to control the car.
This is not the contradiction between electric cars and fuel cars, but the contradiction between mechanical cars and smart cars.
After all, most fuel vehicles now use a large number of electronic equipment to assist in control and implement functions such as autonomous driving.
Especially when AI is becoming more and more powerful, if an organization specializes in training hacker-type AI to attack on car intelligent systems, what should ordinary car owners stop and resist?
So in March this year, Jiang Miao asked the company to secretly find a car factory that can be acquired and prepared to produce a safe car by himself.
The security cars he positioned are not only physically safe, but also online.
…
"Boss, this is a brief situation of the two automobile factories. Please read it." Li Fei, general manager of Panshi Automobile, handed him the two documents.
Jiang Miao flipped it out casually. This is the general situation of the Yongjia factory and the Huangzhou factory.
With two shifts, the annual production capacity of Yongjia factory is 200,000 vehicles, and the annual production capacity of Huangzhou factory is 150,000 vehicles. The total annual production capacity of the two factories is 350,000 vehicles, which is also the acquisition price. Source.
If it is a brand new factory, the investment in these two factories will be very high.
According to the information on the document, the Yongjia factory covers an area of about 1,000 mu, covering four major process workshops: stamping, welding, coating and assembly. The total investment is about 6.7 billion yuan. It was completed in 2018 and has a degree of intelligence. It is relatively high and has produced WM EX5, W6 and other models.
The Huangzhou factory covers an area of about 800 mu, with a total investment of about 20.2 billion yuan. It will be put into production in 2020 and is positioned as a new energy and SUV production base.
Now after so many years of idleness, the value of the factory and equipment has plummeted. If the land was not worth a little money, Hailufeng Company would never have bid 3.5 billion.
Jiang Miao closed the document and looked at the middle-aged Mediterranean man next to Li Fei: "Director Wang, how is the progress of your design department?"
Wang Muhua, the technical director of Panshi Automobile, stood up and replied: "Boss, our automotive design department has completed the first draft, but the details need to be improved. The prototype is being manufactured. This is the first draft plan. Please check it out by the boss."
After taking the document, Jiang Miao looked at it, browsing and asked, "Have you added a lot of bean silk material to your design?"
"Yes, boss. We It is believed that modified soybean silk fiber can replace a large part of carbon fiber, steel and aluminum alloy, and this improvement can reduce the weight of the car a lot."
Jiang Miao saw the material in it replaces that part of the content.
If all the replacement parts are changed to modified soybean silk fiber composite material, the car's own weight can be reduced by 30% to 40% without the battery.
Moreover, this improvement will not only reduce the weight of the car, but also become very strong in the overall strength.
For example, there are a lot of test content in the design plan.
Wang Muhua's team used internal relationships to allow Dousi Laboratory to produce more than a dozen simple frames in small batches, and then replaced these frames on cars purchased from the market, carrying out various impacts and Crush test.
Under the impact of 10 tons of steel coil falling from a height of 1 meter, the new material vehicle body can consume 94% of the kinetic energy through the energy-absorbing structure, and the remaining energy is dispersed through the rigid frame, which can prevent the crew cabin from collapse.
The strength is terrifyingly strong due to the different processing methods of different steel and aluminum alloys.
The body structure of steel and aluminum alloy materials often requires welding, rivets, and screws to be fixed and connected. This processing method leads to its natural weaknesses, such as the insolid welding points.
However, the structure made of modified soybean silk fiber composite material can be formed integrally.
As long as the structure is designed in advance, integrated forming can be achieved through weaving, bundling and templates.
The integrated forming structure has a very high strength under the support of such a high-strength material. Moreover, due to its integrated forming characteristics, the car will not deform easily when it is hit, but will not deform through The overall offset is used to remove the impact force.
During the test of Wang Muhua's team, a high-speed rolling steel coil hit the car away.
If it is a car with ordinary steel and aluminum alloy material, when it encounters a high-speed rolling steel coil, it will basically be crushed into a discus rhythm.
A car with new materials, whether it is pressing the top from a height of one meter or rolling at high speed from the front, side, and back, it cannot crush the car core compartment.
On the contrary, sharp steel bars, dense bricks and stones pose a certain threat to cars with new materials.
For example, the dense steel bars penetrated from the front can indeed block the steel bars, but the car glass cannot withstand it, and the driver and passengers are easily penetrated by the steel bars.
All in all.
Cars made of new materials are absolutely very strong. In various impact tests, large-area impacts are the safest. As long as they do not impact dense sharp tube items, the survival rate of general impacts can basically reach 95. %.
Of course, the premise of this survival rate is that the car does not speed up.
If the car is rushing, even if the car body can withstand the impact force, the reaction force generated by the impact will seriously damage the internal organs of the driver and passengers. Before he knew it, Jiang Miao had already turned to the battery part of the first draft plan.
He found that the battery design of Wang Muhua's team was very large, almost twice the size of an ordinary electric vehicle.
"Why is the battery designed so large?"
Hearing this question, Wang Muhua immediately explained: "Boss, after we use new materials, the weight of the car will be reduced by about 30% to 40%, although the car has become It is lighter, but its wind resistance and high-speed driving stability will all decrease as the weight decreases. "
"I understand." Jiang Miao already knew the ideas of Wang Muhua's team.
"So we use the battery weight replenishment method to maintain a dynamic balance of the overall weight of the car. Moreover, since batteries are generally integrated into the chassis, when we increase the weight of the battery, the center of gravity of the car is pressed down on Below, the stability of the car can be further improved. "
This method can indeed improve its stability for the car.
Wang Muhua continued to add: "As the battery weight has been increased by nearly twice, the battery capacity of the new car will be further increased."
If the previous sponge battery only increased the car's range a little, Now that the body of the new material is added, the overall range of electric vehicles can almost reach about 2.5 times that of old electric vehicles.
This improvement reduces mileage anxiety during driving and can also reduce the layout density of battery swap stations.
No mistakes, one poem, one post, one content, one in 6, one book, one bar, one read!
However, Jiang Miao, Li Fei, Wang Muhua and others are not worried about the construction density of the battery swap station, because capitals from all parties have been engaged in battery swap station projects recently.
Including the three barrels of oil with the traditional fuel industry as the core, they are using their gas station outlets to quickly deploy battery swap projects.
So there will definitely be many battery swap station projects in the future, and there is no need to worry about not being able to find a place to replace the battery.
On the contrary, the safety of the car battery forced Jiang Miao to consider it. He picked up the phone and dialed the number of Lei Bo, the head of the battery business department.
"Hey, Manager Lei, it's me."
"Boss, what are your instructions?"
"Are you at the headquarters?"
"I do some things at the bus company. Do you need me to go back to the headquarters?"
"No, I'll ask about a project I arranged before, which is What is the current situation of that safe battery project? "
"Safe battery?" Lei Bo, opposite the phone, immediately reacted: "There are currently two solutions for this project."
" Tell me. "Jiang Miao took out his notebook and pen.
"The first solution is to use aluminum hydroxide powder, which can reduce the explosion of soybean oil in sponge batteries, but this solution will cause a 13% reduction in the number of cycles of sponge batteries."
"What about the second solution? "
"The second solution is to use soybean oil with phosphate and combined with phosphate, which will also lead to a decrease in its combustion characteristics, but the consequence is that the upper limit of the battery's charging and discharge power is reduced to 88 kilowatts, and the energy is The density drops to 330 kWh per cubic meter, and it will cause too high phosphorus content when refining biodiesel. If the phosphate esters cannot be completely removed, it may cause too high phosphorus content in biodiesel combustion waste, resulting in waste gas pollution. "
Jiang Miao thought about it: "Give up the solution of using phosphate and adopt the first solution."
"Okay, boss." Lei Bo said again: "I suggest to Beijing Energy batteries and Guodian batteries are jointly developed to determine the flame retardant components of power batteries as soon as possible.”
"Well, you can arrange it!"
"Yes."
After hanging up the phone, Jiang Miao also put down the pen and looked at Li Fei and Wang Muhua sitting upright: "The sponge battery contains soybean oil, If you come into contact with a fire source, combustion may occur. What do you think? "
Li Fei thought for a moment: "In essence, to reduce combustion, either suppress the combustion characteristics of combustible materials or isolate combustibles The substance came into contact with the oxidant. "
Jiang Miao did not look up and continued to note Li Fei's thoughts.
"I think to enhance the fire resistance of the new car, we can start from three aspects." Li Fei paused for a few seconds: "First point, enhance the overall strength of the battery compartment to avoid deformation during the impact, causing the battery compartment to rupture. The soybean oil leaked out. "
"This is a method." Jiang Miao also thought this method was good. "The second point is the safe battery solution mentioned by the boss just now. By adding aluminum hydroxide powder, the soybean oil solution inside the battery can reduce the combustion characteristics."
"The third point, I think so, that is, set up several soda powder fire extinguishing devices inside the battery compartment, and even consider laying a layer of baking soda fireproof layer directly on the battery compartment. When it encounters high temperature, it will explode instantly and baking soda powder is turned on. Covering the leaked soybean oil."
Jiang Miao turned his head and looked at Wang Muhua and asked, "Director Wang, is the third method technically difficult?"
Wang Muhua nodded: "Mr. Li's third solution is not technically difficult, it is to increase part of the weight. However, considering that the weight of the new car can be compressed a lot, adjust the weight of the battery and take out part of the weight to set up the fire prevention system."
"Okay, our brand positioning of Panshi Automobile is safety. Without affecting performance, we should enhance the safety of the car as much as possible. This is our philosophy." Jiang Miao has decided to go through three steps. .
While taking notes, Wang Muhua replied, "I understand. For Mr. Li's three improvement ideas, we will add the new car plan as soon as possible."
"Well, next we will Let’s talk about network security issues. "Jiang Miao turned to the part of the auxiliary system of the first draft plan: "Now the functions of autonomous driving and on-board intelligent systems are becoming more and more powerful, but their safety is very uncertain. We It must be taken seriously." Qin Xingzu, the head of the Internet business department who had not spoken, knew that he was about to speak, so he immediately stood up:
"Boss, Mr. Li and Director Wang, I think it is impossible to guarantee absolute security from the software level."
"Manager Qin, your idea is that our new car will give up the smart system? "Li Fei frowned.
Qin Xingzu's expression was serious: "Our department has discovered various vulnerabilities in automotive intelligent systems through technology. Some time ago, I also led a team to use AI technology to train a hacker who specializes in deciphering automotive intelligent systems. AI, through this AI, we only took about three hours to capture most of the smart car systems in China. "
"What?" Li Fei was shocked.
Wang Muhua proposed another idea: "Can we use AI to enhance the firewall?"
However, Qin Xingzu's next words poured cold water on them: "How can the chip computing power of the car computer be confronted with professional hacker computers or even large servers?"
Faced with this essential problem, Li Fei and Wang Muhua were speechless for a moment.
Computing power is the natural weakness of the on-board intelligent system.
Hackers or some organizations can mobilize large servers to brute-force attacks on in-vehicle intelligent systems.
As long as the car to the on-board intelligent system is connected to the Internet, there is a possibility of being captured, and this possibility is very high.
Li Fei had a headache: "If the physical network is disconnected, many of the functions of the car will not be used." "No, there is a way to solve it." Wang Muhua thought of a solution: "The car needs the function of connecting to the Internet, It mainly includes navigation systems, driverless driving and assisted driving. As long as the navigation system is independent and driverless driving and assisted driving are cut off, there is no need to connect to the network to control other systems inside the car."
Qin Xingzu Squinting his eyes, reminded: "Director Wang, I need to remind you that if you use foreign car chips, the other party may leave a backdoor on the chip. This type of backdoor program can sometimes be used through smartphones and tablets. Smart devices such as those that are actively connected to the Internet. "
"Can't even use foreign chips?" Li Fei is one head and two big ones.
Wang Muhua shook his head: "It doesn't matter. Domestic car chips are OK, and there is no problem if you don't need foreign ones."
Jiang Miao finally spoke: "Then let's decide first, to isolate the direct control of the car by the networked system as much as possible, and to use a safe domestic automotive chip. In addition, a backup system with complete mechanical control should be set up to avoid problems with the on-board chip. What causes the car to be paralyzed."
"Okay, I will arrange the boss's instructions to improve the design of the new car." Wang Muhua nodded.
Although I don’t know the prospects of this kind of safety car, if the experience is not bad, Wang Muhua wants to buy one.
After all, no one wants to hand over their lives to intelligent systems that may be out of control.
