Tech Hammer

On the day when he sent Jiang Chenlu to the airport, Ningwei saw his own car for the first time. It was a seven-seater business car. The black body looked thick and majestic. The Beijing A license plate looked more comfortable. The interior decoration was not luxurious, but it should be. Some have them. There is a specially designed table on the back of the middle seat that is very sturdy when turned down. The back of the table is also equipped with high-end pens, notebooks and a stack of manuscript paper. When I opened this small table for the first time, Ning I even felt a little ashamed.

Is this a reminder to him to always think and solve problems?

Of course, Ning Wei thinks this design makes sense. Like today, the two sisters are sitting in the middle row and whispering. There is also a capable young lady in the co-pilot accompanying Liu Wei. This young lady will wait a moment. He will also accompany Jiang Chenlu back to his hometown to celebrate the Spring Festival, so he is the only one in the spacious back row. Of course it's impossible to write anything with a pen, but fortunately the small table is sturdy enough and just enough to hold a notebook.

Opening his laptop, Ning Wei logged into his account at the supercomputing center and called up March's control backend, where he could view March's most intuitive data. The progress is gratifying. Huawei has completed the system transformation and standard interface docking of its three computing and storage centers, and has opened up some of the data under research in March as promised, mainly focusing on the complete set of smart home solutions and Smart car solutions.

It sounds like there are only two directions, but the data involved is also very complex.

In terms of smart car solutions, they include smart electric systems, smart seat systems, assisted driving systems, computing and communication architectures, smart cloud service architectures, etc. Smart electric systems also include power system components, all-in-one Electric drive system and battery management system, etc. The power system components include electric engine, battery system, on-board oxygen supply system, power supply system, powertrain control system. The further breakdown involves mathematics, physics, chemistry, Computer science, materials science, structural science, industrial design, etc...

Theoretically speaking, for these modern technology companies, after opening any research direction, you can see a tree-like structure. Ordinary consumers only need to know the simplest branch names, and let this branch To grow strong enough, what is needed is densely stretched out branches and leaves all over the branches...

Faced with such complex research projects, refined division of labor and streamlined research and development have become the norm in the industry. After all, human energy is limited, and it is impossible for a team that researches battery materials to also build a master control system. Therefore, one Large R\u0026D directions must also have a coordinating department to set standards, understand the research results and progress of each subdivision, and finally make mature products that can withstand market testing.

This is probably the reason why many technology company executives need multi-department work experience, because when senior executives need to coordinate, they often need a longer-term and comprehensive perspective to consider the problem overall. The greatest significance of the intelligent platform built around March lies in its overall planning capabilities.

After unifying standards, it can make up for the shortcomings in research through data resources on large platforms as much as possible, and then allocate resources more reasonably. More importantly, with its own super integration capabilities, it can directly replace the design department and provide the most reasonable overall layout design.

It is not for nothing that March is asked to review those mathematics papers. He is proficient in many mathematical ideas. For directions such as physics and structure that require basic calculations, March has his own set of logical calculation formulas, which are combined with the data of countless research and tests. After compilation and analysis, if there are statistics on the preferences of various consumers in the data, and combined with sales data of similar models, a super-intelligent integration and design system will be initially built.

The specific method is that March will first build a set of mathematical models based on these massive data, and then use the mathematical models to materialize the final design drawings. Of course, the design drawings generated in March are different from ordinary design drawings.

For example, at this time, Ning Wei saw the comprehensive design drawings of three smart concept electric vehicles recently generated by March in the background. The size is 2.68TB. Yes, the three pictures are nearly 2700GB. When the mouse selects one of them After driving the car, the computer started to lag for a long time before the 3D frame panorama of this futuristic car was displayed. When the mouse selected a certain position, it became even more laggy and it took a while to display. Detail of the location of the car.

It was as if Ning selected the steering wheel for the mouse at this time. Soon a steering wheel and a transmission shaft connected below replaced the 3D diagram of the entire two cars. The software and hardware versions of the entire steering system will be prompted next to it. The software can view the code in the master control. The hardware section allows you to view the specific connection parts, how to ensure safety and achieve basic functions, and even indicates the recommended materials and material standards.

For example, the smart electric car shown in the background in March was probably influenced by the Chinese people's preference for space. The wheelbase was designed to be relatively long, so in order to improve driving convenience, the vehicle can be more comfortable when driving in the city. For flexibility, active rear-wheel steering technology is also added. The rear wheels can turn up to ten degrees, and this active control system is also included on the steering wheel.

Click on the steering wheel to see the mechanical structure and active control system that implements this system. For example, how this rear steering active control system collects vehicle driving data, how to judge the required steering angle of the rear wheels through vehicle driving data, and issue instructions. Give execution. According to Ning Wei's inspection results, this mechanical structure is not complicated at all. It is nothing more than adding a steering gear and steering rod to the rear axle. However, this active control system has a very high gold content.

After selecting Return and waiting for a long time, he finally returned to the vehicle interface. Ning Wei entered the battery in the image search bar, and then the entire body frame disappeared, leaving only the entire battery and data.

The battery of this electric car designed in March is mainly concentrated on the chassis of the car, but there are two more on the part of the roof that is not covered by the sunroof. According to the explanation of the picture, these two batteries are used as backup batteries and will be used in the main battery of the chassis. It will only start to actively intervene in the kinetic energy system when it is less than 5%. Under ideal conditions, these two spare batteries can last about 150 kilometers, which is enough to find a charging station.

At the same time, when these two backup batteries are activated, the chassis main battery pack enters a state of only charging and not discharging. When the vehicle is started, energy recovery will continuously charge the chassis main battery. According to ideal calculations, when the two backup batteries are charged When it is consumed to 5%, it can charge at least about 10% of the main battery pack. Then the backup battery enters a resting state. At this time, the car's kinetic energy recovery function starts to charge the backup battery. In this case, the total of both sides can probably last. Dozens of kilometers...

What’s even more frightening is that part of the roof skylight is designed as a solar collector. If it’s a sunny day, the efficiency of charging the backup battery while the vehicle is driving is very impressive...

This Russian doll-like battery life design made Ning Wei want to give the March Pen a thumbs up, but seeing that the theoretical battery life of the main battery alone can reach an astonishing 1,300 kilometers, Ning Wei resisted the urge.

When things go awry, there must be evil. I have never heard of anyone who can achieve a range of more than 1,000 kilometers for industrialized pure electric vehicles. The main battery of this car can last for 1,300 kilometers, and the two backup batteries can last for 150 kilometers. Then the Russian matryoshka can run for dozens of kilometers. This is going up to 1,500 kilometers. This kind of car can really be built. , it is estimated that the electric vehicle market will be unified soon.

This is no longer a question of whether the system design is advanced or not, but the battery technology has been revolutionized in March. Especially after Ning Wei briefly browsed the introduction of the battery system, under the premise of no loss of battery performance, the main battery and The theoretical estimate of the charge-discharge cycle process of the backup battery can reach 1,700 times. If the wear and tear can be accepted within 20%, the number of times can reach 3,500 times, and you will realize that this matter is definitely not that simple.

So Ning Wei waited patiently for the internal structure of the battery to be loaded, and then began to delve deeper. As expected, March very thoughtfully incorporated the thermoelectric materials it had designed into the internal structure design of the battery.

Yes, the material is a flexible thermoelectric material that Zeng Ningwei helped Professor Tan research. Originally, the carbon nanomaterial was used to replace Bi2Te3 and its alloys. The main application direction is actually some wearable electronic products, but it was used here in March. The mathematical model studied at that time was optimized, and a carbon nanosphere with a hollow middle was designed as a battery anode material...

The new hollow design allows the device to retain more charge, which can increase the current battery's power storage capacity by 300%. Coupled with Huawei's own fast charging and discharging technology, it becomes the basis of this battery design. Of course, there are many remarkable technical details in this battery, such as the internal design and structure of the battery, positive and negative plates, separators, electrolytes, tank shells, connecting bars, poles, etc. , as well as redundant safety design with increased battery energy density, etc...

But these people are too lazy to delve into it, because the anode materials of batteries are currently limited to industrial mass production. In addition, the placement of backup batteries on the top layer and the design of solar panels also greatly increase the cost of the entire vehicle. You must know that with such a heavy battery running away, the safety requirements of the entire vehicle body structure are also higher. If you want the body Being lighter requires the use of carbon fiber materials with stronger structures. This material is not only expensive but also crash-proof, and is obviously not suitable for family cars.

Therefore, the entire car needs to work on the support structure. In March, a complete plan was indeed given. Theoretically, it is extremely feasible. Ning Wei did some mental calculations. Even if such a thing enters the stage of industrial mass production, it will only cost about one car. The cost of a car alone starts at least three million. If the battery really uses those carbon nanomaterials prepared in the laboratory, the ex-factory price will continue to rise, and the volume of mass production in a year will probably not exceed three digits. .

Of course, these costs do not include the various high-end production equipment that need to be purchased in order to mass-produce this car. If you add in the various sensors, radars, cameras that are piled on top of each other in order to achieve various high-end assisted driving functions...

how to say……

If Liu Wei really works hard and gets his laboratory out, I wonder if he can really follow this plan and try to build such a super electric car for fun, but it will be seen by the big guys at Huawei. This design will probably make your hair fall out with worry. It’s like some architects don’t consider all kinds of basic mechanical knowledge when designing a building. They just care about it looking good and the renderings are beautiful. Huan, the construction engineer just wanted to rip off the designer’s forehead to see if this thing is the culprit of the earth’s water shortage.

It just so happened that designers like March couldn’t be fired.

But what Ning Wei never imagined was that when he was madly complaining about March's irresponsible ideal design, Huawei's strict boss was holding the same design drawing with the visiting Apple technical engineers. They were bragging.

…

Yes, just after a round of tiring negotiations, Apple's engineers who rushed to Shenzhen in a low-key manner were invited to the multimedia conference room of Huawei's headquarters. At this time, what was displayed on the big screen was a new generation of home electric devices designed in March. car.

"Everyone, you should know that it has only been a week since Dr. Ning proposed the establishment of an intelligent resource integration platform. It was only the next day that we officially started to get involved in data integration and resource cooperation with the platform, plus the time for various technical authorizations. The March Intelligent Manufacturing Platform only took three days to integrate our data. In just three days, the March Intelligent Platform has integrated the most ideal new model in the world at this stage based on the existing insufficient data. The complete engineering drawing of the electric vehicle, we named it SPEV.N1 smart electric vehicle."

"These are the parameters of the entire vehicle. The weight of the entire vehicle is 3.67 tons. The body is very heavy, right? But please take a look. In theory, this pure electric vehicle can have a range of more than 1,800 kilometers, even under optimal conditions. , this mileage can be increased, I think everyone knows what this means. In addition, you can also take a look at its intelligent safety system, and the assisted driving system implemented through the cloud platform, which is absolutely world-class technology."

"It is no exaggeration to say that this car is at least ten years ahead of the world's electric smart cars! I don't think I need to explain the concepts of three days and ten years to you. In order to express our sincerity, this SPEV The complete set of engineering drawings of the N1 smart electric car is now available for everyone to view. You can evaluate whether this car can be built and its value to Apple's car-making plan. And what I want to tell you is that similar cars The engineering drawing intelligent platform has provided three different design solutions."

"This is the benefit of joining our intelligent platform. I had an in-depth exchange with Dr. Ning Wei. Our original intention in building this intelligent platform was never to create a technology monopoly, let alone to exclude friendly businesses, but Really carry forward the spirit of the Internet to the extreme. Share data, share patents, and then share the technology after resource integration."

"As long as you join our platform, agree to the various interface standards proposed by the platform, and provide all laboratory data to the platform, it also means that you can share these resources. Today's engineering drawing can only be viewed here, but if Apple If you are willing to join us, you will be able to access this information at any time in your office in Silicon Valley in the future.”

"And the sooner you join, the more you can get. You can see that the entire car's intelligent central control platform and intelligent voice control platform are tailor-made based on the Hongmeng system. Why? Because currently only Huawei is the intelligent platform Data is connected, so this is a set of design solutions specifically based on the Hongmeng system. From the entire system to every chip, it has Huawei’s technical imprint. Then after Apple joins, it will naturally require the platform to design Design solutions that support IOS systems.”

"Similarly, after our patents and technology credits are granted, Apple will also be able to upgrade its own intelligent voice control system. This may not only be used in cars, but also in all Apple products. I also discussed this with Dr. Ning Wei in depth However, Dr. Ning believes that frank and open competition among our business partners will ultimately benefit all consumers around the world. On the contrary, those blatant and shameless tactics in business can only cause the regression of human intelligence."

"So the purpose of our smart platform is fairness, fairness, and fairness! After joining the platform, everyone enjoys the same resources. Apple can also enjoy the resources that Hongmeng can enjoy. So you still think that for Huawei's next generation Is it hard to accept that smart products can provide some help within their capabilities? We just need some chip support, but you can obviously get more."

"Think about it, the IOS ecological closed loop will have richer usage scenarios, a more perfect ecological environment, and the resource integration of the entire platform will be tilted to the world's highest level of solutions. Apple's press conference will no longer be stuck in hardware design. The embarrassment of no innovative scientific research. Apple’s automotive business will not stop at PPT. How much confidence can an epoch-making Apple concept electric car bring to investors?”

"There are not many such opportunities. As we said in the letter to Mr. Cook, we invite Apple to cooperate with us with great sincerity because we all have lofty beliefs and strive for customer experience. , a company that is willing to give everything. Now it’s time for you to pay something trivial for this belief to show your sincerity as a friendly businessman. Do you really think this is too much?”

"I won't say anything else. The next hour is a break. You can browse all the data here. The negotiation will continue in an hour. I won't disturb you anymore. Thank you."

…

Just like that, when Yan Ming finished his passionate speech at the Huawei headquarters in Shenzhen, Liu Wei also parked his car steadily in the parking lot of the airport.
