The layman looks at the bustle, and the insider looks at the doorway.

The wonderful debut of the driverless bus in Sioux City just provided a new talking point for the majority of ordinary netizens.

But companies like alphabet, whiteness, Tesla, GM, Uber, Apple, Toyota, and Intel, which are engaged in related technology development, almost didn't lose their eyes.

Behind the unmanned driving technology shown by Xinghai is the comprehensive leadership of Xinghai Technology in various fields such as cameras, computer vision, radar sensors, navigation and path planning.

It has reached the point of beating all companies, or rather, they are no longer at the same technical level as Xinghai Technology.

But how is this possible?

The United States has been researching unmanned technology since the seventies of the last century, and the domestic National University of Defense Technology has also entered the field in the nineties of the last century.

And what about Xinghai Technology?

They have only been established for more than 3 years, how can they be ahead of them so quickly?

Not to mention the software, Chen Xu is a Turing Award winner, and has also developed the world's first intelligent software, and may have mastered some of the technology at the bottom of the box in the field of control has not been announced.

However, many companies think that they are much ahead of Xinghai Technology in environmental perception devices such as cameras and satellite navigation, and they don't understand how Xinghai Technology can be unbeatable?

It's a fantasy.

But no matter how much you don't believe it, it's useless, the driverless buses in Sioux City are running on various roads in the city, facts speak louder than words, they are indeed inferior to people.

I don't know what the mood of foreign companies is for the time being, but when Li Yanhong, the founder of Baidu, heard the news, he seemed to be ten years old overnight.

The former whiteness is the head of BAT, which is worthy of the name, and the vine is just a child, but as time goes by, the "internal affairs are indecisive to ask Baidu", and the grave grass is already a foot high.

Six profitable sectors, social (post bar), comprehensive information (Baidu News and Baijiahao), map (Baidu map), browser (Baidu browser), video (iQiyi), artificial intelligence (unmanned.

Now except for unmanned driving + maps, everything else is basically old and crumbling.

Li Yanhong has always fantasized about using artificial intelligence to achieve corner overtaking and reproduce the glory of whiteness in the past, and he has high hopes for unmanned driving technology, and even in 2019, because he was the first to get an unmanned driving license, he was once full of confidence.

But in the end, this is the result.

There is no hope for whiteness to rise again.

Li Yanhong's heart is like ashes.

And it turned out to be exactly what he expected.

After Xinghai Technology entered the search field, Baidu's stock price continued to fall, from $30 billion to $20 billion.

After Xinghai launched a powerful unmanned driving technology, Baidu's stock price fell by 10 percentage points again.

But no one cares anymore.

Whiteness has long been like an outdated star, it has become a thing of the past, whether it is dead or alive, no one cares at all.

Wusongjiang Science and Technology Park, Suzhou City, Xinghai Group Headquarters.

When the debut of the driverless bus in Sioux City was a complete success, Lanxi set up a strong sales team to go to the whole country to discuss cooperation and agency matters with local governments or enterprises.

As for the overseas market, the current environment is not mature, after all, not every country has introduced policies to support unmanned driving like China, and there are many interests involved.

It's like mobile phone payment, how convenient and fast? However, most countries in the world do not support it, such as Europe, the United States, Japan and South Korea. Because mobile phone payment has moved the interest cake of big capital.

Of course, Xinghai Technology's unmanned driving technology has also moved many people's interests.

However, Xinghai relied on his strong strength to suppress those opposing voices, such as the Sioux City government, in fact, there were also opposing voices at the beginning, but the top leaders and the provincial government have already unified their opinions.

Eventually, Sioux City became a model city for driverless buses.

After the regular meeting in the morning, Chen Yanan, who was promoted to deputy director of the project department, went to the alloy manufacturing department of the Institute of Materials Science on the fifth floor.

The huge laboratory is full of all kinds of cutting-edge research equipment, and Chen Xu, who is wearing a dust-free suit, is talking to Dr. Yang Xuantong, the head of the Materials Research Institute.

Chen Xu asked, "What's the matter?"

Chen Yanan said: "The technical department has developed a strong electromagnetic wireless charging module for buses, and we plan to launch wireless charging buses in the near future, as well as wireless charging piles, what do you think?"

Chen Xu asked: "The bus is an electromagnetic ground pile?"

The so-called electromagnetic ground pile is to bury the electromagnetic induction strip 5 cm underground in the bus station, which is connected to the power grid, and the car can be charged when entering the station.

However, the charging effect of the electromagnetic ground pile is not good, and at present, only the Han side of Asia has opened a special line.

"It's not ~ not that much trouble. Chen Yanan shook his head, took out his mobile phone from his pocket, and found the design drawing for Chen Xu to see, "It is like a lamppost, about 3 meters high, set up at the bus stop, and the wireless charging module we developed is arranged at the top." ”

After a pause, Chen Yanan said: "Compared with traditional electromagnetic ground piles, my technology is more advanced, the charging speed is faster, and it has the possibility of commercialization." ”

Chen Xu looked at the design drawing for a while, returned the mobile phone to Chen Yanan, and said with a smile: "The design is okay, you can find a pilot city to experiment, but there is no need for large-scale experiments for the time being, and we should focus on the new battery for now." ”

Chen Yanan asked, "What do you mean?"

Dr. Yang Xuantong next to him smiled: "Mr. Chen is talking about graphene batteries. ”

"Graphene battery?" Chen Yanan questioned, and then said: "This thing is difficult to achieve in a short period of time." ”

As the project director of a technology company, Chen Yanan is naturally very familiar with international cutting-edge technology.

She knows that the graphene battery is a new type of battery developed by using the characteristics of lithium ions to shuttle rapidly and heavily between the graphene surface and the electrode.

According to data published by several laboratories around the world, graphene batteries can store three times the best power on the market, and electric vehicles powered by this battery can travel up to 1,000 kilometers and charge in less than 10 minutes.

The second is resistant to heat and cold, minus 100 degrees Celsius, it can achieve 50,000 stable cycles, even if the battery cell is exposed to flames, it will not catch fire or explode.

There is also a long lifespan, according to the most conservative estimates, graphene batteries can last at least 10 years.

It can be said that graphene batteries are the future development direction of the battery industry.

However, graphene is very close to the situation of nanomaterials, and many of the special properties of graphene are based on its monolayer structure, but there is no hope for obtaining a graphite monolayer with an atomic thickness in batches in the next decade.

In other words, even if a graphene battery is made, it will be very expensive because of its complex preparation process.

However, what Chen Yanan didn't expect was that Yang Xuan said endlessly: "We have developed a new type of CVD equipment, which can realize the continuous preparation of single-layer graphene, which can reach up to 500 meters at length."

Theoretically, we can already carry out mass production of graphene batteries......"
