Artificial intelligence is an opportunity and a challenge. Experts suggest that supervision should be strengthened from all aspects.

CCTV News:As an important part of Cyber Security Publicity Week, the 2023 Cyber Security Expo is being held in Fuzhou. The reporter noted that how to better develop the artificial intelligence industry attracted the attention of the participants. Many experts believe that although generative artificial intelligence can greatly facilitate and improve human life style, it also poses a new challenge to network security and needs to strengthen supervision from all aspects.

Experts pointed out that any technology has two sides, and there are a series of security risks hidden behind generative artificial intelligence, which pose new challenges to national security, social security, network security and data security.

In terms of security, experts pointed out that excluding human intervention, the security problem of artificial intelligence itself is also obvious.

China computer federation (CCF) Computer Security Professional Committee Member Degree:First, at the source, the data may be poisoned and polluted, so the original training data may have problems. Second, when training, there may be a big data discrimination algorithm in it, and it may not be a fair algorithm, which will lead to problems in the results. Thirdly, there will be a feedback mechanism in the final output stage, and the feedback mechanism may inject some malicious data or samples, which will also lead to the deviation of the answers obtained by this model.

So, how to deal with the hidden dangers of artificial intelligence? Experts said that this requires joint efforts from the supervision, practitioners and enterprises.

Li Xinliang, Expert of Guangdong Digital Government Network and Data Security Emergency Response Expert Group:In view of the security risks that AI may bring, I personally feel that it is necessary to speed up relevant legislation at the national level and formulate relevant industry standards as soon as possible. In addition, for AI practitioners, it is necessary to strengthen the corresponding training so that they can carry out it at the level of national laws and regulations when using AI technology. From the enterprise level, we must fully consider the compliance of collecting citizen information, and at the same time, we must strengthen the relevant actions of data protection in the transmission and storage of these collected data.

Geely star is the first to experience, and it is just outside and soft inside.

The "CMA architecture" planted in those years and together is now beginning to bear fruit in the brand-Xingyue, Xingrui, and now Xingyue L, which has set a record for the largest size of CMA.

Although it is named "Xingyue L", the design of this car is completely different from Xingyue. The latter tends to be dynamic and young, while the former pays more attention to maturity and stability.

Although the style orientation is different, the overall design language remains the same, which is also the characteristic of all models at present. A set of recognizable design allows unfamiliar people to recognize the brand without looking at the logo, which is very beneficial to the creation of brand image and the setting of product positioning.

The overall dimensions of Xingyue L are 4770*1895*1689mm and the wheelbase is 2845 mm.. It is reasonable to say that this size can be counted as a medium-sized SUV, but it is still called a compact SUV. One of the reasons is that the CMA architecture was originally aimed at compact models. As a result, the Xingyue L will look a bit "have no martial ethics" when compared with other compact SUVs in the future, similar to the previous Xingrui.

To sum up the shape of Xingyue L in a few words, there are probably: stable, thick, hard and strong. The headlights, grille, rearview mirror, window and wheel hub are all one size larger than the previous models. Although they lack the agility that young people like, they give people a solid and reliable psychological feeling, which is obviously a model for family use.

Matrix headlights are a bright spot, with 126 LED beads, which can control the switch and light and shade separately to ensure the brightness and lighting range, and at the same time, more lighting effects can be achieved through OTA in the later period.

Xingyue L’s car paints are available in six colors, including oyster white, aurora silver (as shown in the picture), basaltic gray, jet black and Mars red, as well as a distinctive "Cuiyu Blue", which is not blue or green, inspired by the mountains and mountains, and at the same time extracts the green texture of traditional porcelain and natural cuiyu. The cost of this car paint will be higher, and it may be available in limited quantities after listing.

When you open the car door, the little oppressive feeling brought by the appearance suddenly disappears, and the warm home atmosphere comes to you. The length of the triple screen across the center console is close to one meter, and the resolution of each screen has reached 1920X720.

This shooting vehicle is a test car, and the screen can’t be lit. The visual effect is quite good in the all-black state, and the overall feeling is very strong. At the recent Shanghai Auto Show, we saw the effect after lighting. The screen quality is very high, but the white theme still has a sense of separation. We look forward to the effect of the black theme.

The air conditioning outlets on both sides are directly opened on the huge black panel of the triple screen, which is a cost-free operation and of course brings good visual effects. Touched by hand, the edge of the opening is very round, and there is no cutting feel, which shows excellent workmanship.

The shape of the shift lever is similar to that of Xingyue and Xingrui, but the unlock key is cancelled, and the operation logic is the same as that of XC40. Shift the shift lever twice. The physical buttons in the air-conditioning control area have been preserved, which I praise.

Previously, the interior was decorated with palindromes, but Xingyue L was replaced with woven texture. There was a red and blue gradient stitch between the white stitches on the decorative board. At first glance, it was complicated, but at second glance, it added a little vitality to the interior.

The interior of this car is a combination of beige and red, while the Cuiyu blue model will be decorated with dark green and gold, which is more luxurious and mysterious. The roof is completely covered with suede material, and the cost is burning.

With such a large size, the rear space will naturally not disappoint, and the seat is wide, which provides good support for my whole body. The backrest angle can be adjusted, and the overhead space is about 15 cm. Because the electric seat of the vehicle can’t move, the passenger seat in the picture is actually in a backward position, which means that even if I have a more indulgent sitting position in the passenger seat, another passenger with a height of 180cm can still ride comfortably in the back row.

The luggage compartment has a great depth, but because the backrest of the rear seat is inclined, large items can’t be put in the depth. Open the lower cover of the luggage compartment, and there is a storage compartment below. After putting down the rear seat, the volume becomes very considerable, and the loading surface is only slightly inclined.

The vehicle being photographed is equipped with a 2.0T medium-power engine, with a maximum power of 218 HP and a maximum torque of 325Nm, which is between T5 and T4. It will be matched with a 7-speed wet dual-clutch gearbox and accelerate 7.9S at zero speed.

The Xingyue L will also have a 2.0T high-power engine with a maximum power of 238 HP and a maximum torque of 350Nm (which can be supercharged to 380Nm), matching 8AT and accelerating for 7.7 seconds. The performance gap between high and low power is so small that it is really rare. I wonder how much difference the price will be at that time.

It is expected that the price of Xingyue L will overlap with the mainstream joint venture compact SUV to a large extent, or even be cheaper. From this static observation, we can see that Xingyue L has obvious advantages over the joint venture SUV in terms of space, design, material selection and configuration. I look forward to the follow-up dynamic test drive and experience the strength of CMA architecture in mechanical and electronic aspects.

Quantum computer has just entered its ＂electron tube era＂

　　Although I have heard the name of quantum computer countless times, like all concepts with the word "quantum", most people don’t know it.

　　The concept of quantum computer was put forward in 1980s, and it has been put into research and development for 20 years. So far, none of them has really gone out of the laboratory. But it is said that it will be very powerful. Google, IBM, Alibaba and many start-ups are competing to be the first to achieve "quantum hegemony", that is, to make quantum computers faster than traditional computers in a computing task.

　　After a superficial understanding of the principle of quantum computer, you will find that it is not much different from the computer we are familiar with.

　　Quantum computer: a quantum version of the computer

　　"Don’t think of the quantum computer as a brand-new system, it is an extended version of the classic computer, imitating the classic computer everywhere." Professor Han Zhengfu, chief scientist of Anhui Wentian Quantum Technology Co., Ltd. and key laboratory of quantum information of Chinese Academy of Sciences of China University of Science and Technology, told the Science and Technology Daily reporter.

　　Han Zhengfu said that the classic computer represents the number 1 or 0 by the voltage level, which is a bit.

　　The quantum computer corresponds to a quantum bit (Q-bit), which may be an electron whose spin arrow is up or down, or a light wave that vibrates vertically or horizontally … …

　　Traditional computing circuits are composed of various "logic gates", which correspond to various "quantum logic gates" of quantum computers. According to certain rules, the 0 and 1 of storage bits are changed.

　　Han Zhengfu said: "The traditional computer is played like this: a row of memory bits is written with an initial value (such as 10011001). Next, several steps are performed, and at each step, the numbers in the memory are transformed into another set of numbers. Stop after the program and read the numbers inside, such as 00101010, which is the calculation result. " The same is true of quantum computers.

　　The difference between quantum computers is that Q-bit is particularly flexible and not as rigid as Bit. It is both 0 and 1. For example, it is 60% 0 and 40% 1. This gives it super powers. You have to learn a little quantum mechanics to understand the mystery of Q-bit.

　　Fuzzy and accurate Q-bit

　　What do you mean, "it’s 60% 0 and 40% 1"?

　　Take a refresher course in senior high school physics: Experiments at the beginning of the 20th century found that substances are too small to be measured accurately. Because measurement means interference, even if you only look at it. When the object is so small as quantum level, its state will be completely destroyed by observation. By the way, the "touch-and-break" effect is used in quantum communication. Using quantum to carry the password can make it possible for someone to eavesdrop on this password signal and will certainly be found out. ) This is called "uncertainty principle". The smaller things are, the more blurred they are. You go to measure the position of an electron, this time in Beijing and next time in Tianjin. We can only say that a quantum "has a high probability of being in Beijing", "has a high probability of spinning arrows rushing up" and "has a high probability of lying flat and vibrating" … …

　　These probabilities can be determined by multiple measurements, although the reading of a single measurement is not necessarily.

　　Therefore, quantum bits are fuzzy and accurate: when the same number is read, 0 is read, and sometimes 1 is read; But after reading it many times, the probability of 0 will tend to a constant value, such as 60%.

　　Why is quantum computing faster?

　　"In a traditional computer, a high voltage is superimposed on another high voltage, which is still a high voltage; The superposition of qubits is different. " Han Zhengfu said.

　　Quantum bits store a vector, just like a clock, which corresponds to the probability.

　　The hour hand can point to zero (the qubit reading is 100% 0) or to three (the reading is 100% 1). Or point to 1: 30 (50% is 0 and 50% is 1), or point to any angle.

　　Traditional computers store "10011001".

　　Quantum computers store "bells, bells, bells, bells". Please imagine a row of clocks hanging in the lobby of the hotel.

　　In traditional calculation, 1 and 0 are superimposed to 1, and then a 1 is superimposed to get 0.

　　In quantum computing, the superposition of "three points" and "zero point" is "1: 30", and then the superposition of "three points" results in "2: 15".

　　Q-bit is more expressive than bit. A Q-bit can contain infinitely complex numbers. In this sense, "one is more than one". A Q-bit input transformation is equal to the transformation of multiple digits together, which is called "parallel calculation".

　　When the potential of parallel computing reaches its limit, the computing power of quantum computer is 2 n ∶ 1 compared with traditional computer.

　　But it should be emphasized that the results of quantum computers come from probability statistics. Quantum computer is different from tradition, it has to repeat the program again and again, and read it again and again (the result is different every time). Repeatedly, enough times (the reliability of probability exceeds 99.99999%), the ratio of each qubit to 1 and 0 is counted, and that is the required number. So when it comes to less complicated computing tasks, quantum computing may be slower than classical computers.

　　Rainbow and zebra

　　Before the advent of quantum computers, mathematicians were imagining to use the "rich connotation" of quantum bits to greatly reduce the calculation time. But so far mathematicians have only proved that quantum computing is much faster than traditional computers in two scenarios.

　　The first is to crack RSA algorithm. RSA is the most commonly used encryption method at present, and its mechanism is the difficulty of factorization — — Multiplying two large prime numbers is very simple, but splitting the product into two prime numbers may take tens of thousands of years for the computer.

　　Therefore, banks can send a number of thousands of digits publicly and master its two prime factors without worrying about someone working out these two prime factors — — Used to make private digital keys.

　　But more than 20 years ago, Peter Shor proved that an algorithm based on quantum computer can easily decompose factors, which also greatly increased the interest of academic circles in developing quantum computers.

　　Another possible application is "searching large unordered databases", or "looking for a needle in a haystack". Traditional computers can only compare targets one by one, while quantum computers can calculate in parallel. If the traditional computer time is t, the quantum computer time is "root t" The former takes 1 million hours, while the latter can be solved in 1,000 hours.

　　In addition to the above two kinds of calculations, quantum computers are also expected to make great achievements in chemistry, pharmacy and other fields in the future. The reason is: unlike traditional computers, quantum computers are real analog computers, which can reproduce the real nature (physicist Feynman first pointed this out).

　　The 0 and 1 of traditional bits are equivalent to black and white, and the "hour hand that can point at any angle" of quantum bits is equivalent to a full-color spectrum, which can display any color.

　　If the traditional memory is zebra, the quantum memory is rainbow. The world is colorful, and it is certainly more direct and convenient to describe the world with rainbows.

　　Just getting started

　　Quantum is very fragile and will collapse easily.

　　"To encode information in a very tiny thing, such as an electron or a nucleus, we must first isolate it and let it not work with the surrounding area. This subtle control is very difficult. " Han Zhengfu said.

　　All kinds of quantum carriers are accompanied by unique difficulties, for example, photons are always advancing, and electromagnetic fields can’t control them, which is very troublesome to control. At present, researchers are probably experimenting with dozens of carriers: electrons, photons and ions in traps … …

　　Han Zhengfu said: "The Key Laboratory of Quantum Information of the Chinese Academy of Sciences, which belongs to the Chinese University of Science and Technology, now has more than 50 associate professors, 150 doctoral students and nearly 30 postdoctoral students. There are many different groups in a team. Although the things studied are understandable to each other, there are specialties in the field, such as ‘ Make silicon ’ Some people will study the processes that the semiconductor industry cares about, such as exposure and cleaning; ‘ Do light ’ Research laser generators, oscillators, optical fibers and the like. "

　　"Domestic research on quantum optics began in the early 1980s. There are many more people now, but they are still unpopular. Professionals are scarce. " Han Zhengfu said, "In fact, there are not enough talents in the world. So Google spent hundreds of millions of dollars to dig a team from the University of California, Santa Barbara, mainly studying superconducting quantum computers. "

　　At present, major companies and research institutions are still improving the quantum bit quantity — — Strive for dozens of quanta to be stable at the same time, and don’t collapse too quickly. Superconducting machines cost millions of dollars to make the environment close to absolute zero. The engineering experimental machine is improving, but it is not known when it will be practical.

　　Looking back at the first computer ENIAC in 1946, 18,000 electron tubes were used, which were glass tubes in which electrons were evacuated and flew. ENIAC weighs 30 tons and only calculates 5000 times per second. Without the semiconductor revolution more than ten years later, there would be no computers and mobile phones today.

　　It should be said that the quantum computer has just entered its "electron tube era". (Science and Technology Daily reporter Gao Bo)

Education informatization speeds up in an all-round way, and Acer builds a wireless digital campus.

　　In the process of promoting educational informatization in China, primary and secondary schools have accumulated a good foundation and practice in the construction and application of digital campus after years of exploration.

Leading intelligence： the cutting-edge technology of battery recycling related industries.

On April 5 th, the financial sector reported that some investors asked Pioneer Intelligence on the interactive platform: Does the company arrange equipment research and development for battery recycling, disassembly and reuse? Considering the large amount of batteries used in the future, recycling will also have a considerable scale.

The company replied: the company continues to pay attention to the cutting-edge technology of battery recycling related industries.

Dunhua News Network transformed consulting rooms in 14 hospitals and sent 38 bloggers for physical examination. Xiaohongshu launched a friendly action for women’s physical examination.

Such as writer Susan • Sontag wrote in Metaphor of Disease that everyone may face the disease, but in thousands of years of culture, some diseases have been labeled, making it difficult for people suffering from the disease to face themselves.

On the occasion of International Women’s Day on March 8th, Xiaohongshu Health launched the activity of "It doesn’t matter if there is something wrong", which helped more people to eliminate their sense of shame and anxiety through online topics and practical actions such as knowledge popularization and physical examination of 38 bloggers, and held the "It doesn’t matter meeting", which provided a place for public discussion on the topic of gynecological diseases that was originally shy. It is also to send care to women through the transformation of offline hospitals.

Susan • Sontag said, it doesn’t matter, the disease is just a disease, not a disaster from heaven, so don’t be ashamed to say it.

And Xiaohongshu also wants to tell you that there is something wrong with it, and it doesn’t matter. Action is the certainty of physical and mental health.

　From slogan to action "it doesn’t matter"

China Reproductive Health Research Report 2022 shows that among more than 3,100 women in 31 provinces and cities, 71% have gynecological symptoms such as irregular menstrual cycle, abnormal vagina and leucorrhea, but only 57.5% choose to see a doctor after gynecological symptoms appear.

Most of the shackles of women’s fear of illness and medical treatment come from the metaphorical "shame" and "fear" of illness. In addition, the uncertainty of diagnosis and the worry about future results have also discouraged many patients.

How to liberate from the metaphorical pressure brought by the disease, Susan • Sontag gave the answer: to get rid of these metaphors, we can’t just avoid them, they must be exposed, studied and exhausted.

In the online activity of "There is something wrong, it doesn’t matter", Xiaohongshu invited doctors as white coat friends to promote knowledge and ideas. And encourage more users to share the most authentic medical experience. Promote action with popular science, radiate the whole people from women, and reduce the anxiety and shame of ordinary people about diseases.

At present, there are 210 million exposures and 1.76w notes on the series of topics with # small problems and small methods. In addition to inviting many gynecologists and surgeons such as Dr. @Jojo to conduct popular science on women’s health; Xiaohongshu also launched the # It doesn’t matter action with 38 bloggers for physical examination. At present, many bloggers, such as @ Lahongshang @vivi Keaduo @ Sophie and Azhe, have shared the experience of gynecological examination, which is a name for gynecological diseases. Driven by them, more female users are willing to overcome shame and make changes for their health.

At the same time, on March 7th, Xiaohongshu also held a "Never mind meeting", inviting female characters from different fields, including doctors, writers, talk show actors, screenwriters and so on, to share their experiences and stories of coexistence with Xiaoxiao.

In gynecological examination, many women will be afraid of pain, and even wonder if they are too "melodramatic". In fact, individuals’ feelings of pain vary from person to person. As Si Wen said, we should respect the threshold of self-pain. Courageously expressing your pain during the examination is also a key step to face up to the disease.

From Online to Offline Friendly Clinic: A Closed Loop of Community Care

In recent years, the popularization of health knowledge is also driving the change of social concepts and promoting the public to face diseases and daily life with a correct attitude.

The fear and shame before seeing a doctor can be dispelled through popular science and experience sharing, but the discomfort in the actual examination is easy to leave a psychological shadow on women.

Ding Ding, director of the Department of Obstetrics and Gynecology of Huashan Hospital (Baoshan Campus) affiliated to Fudan University, told reporters that in terms of physiology, the discomfort caused by gynecological examination may be the feedback of most people, especially in the first or unfamiliar environment. "Some patients will also tell me that they don’t know what examinations to do, or what items to do in the routine physical examination of gynecology, and how often to do them … …”

It is not difficult to see that, in addition to professional medical advice, women also expect a warm and comfortable medical environment. Based on this, Xiaohongshu linked Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine, Huashan Hospital affiliated to Shanghai Fudan University (Baoshan Campus), Second Affiliated Hospital of Zhejiang University School of Medicine, Union Medical College Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology, Xiangya Second Hospital of Central South University, Henan Provincial People’s Hospital, Obstetrics and Gynecology Hospital affiliated to Fudan University (Red House), Hunan Provincial People’s Hospital, Shanghai Tongren Hospital, Shanghai Jiading Central Hospital, Chengdu Women and Children Central Hospital, Changsha Central Hospital (Red House)

Taking Huashan Hospital as an example, Director Ding Ding revealed that through the warm environment transformation, such as relaxing and encouraging floor stickers, gynecological examination posture wall stickers, "it doesn’t matter doll" decoration, and men’s stop to set up illustrations, we strive to create a "it doesn’t matter, relax and friendly clinic" to alleviate everyone’s fear and worry about gynecological examination and treatment and convey the warm concept of "it doesn’t matter, relax".

In order to optimize the experience of women’s physical examination, many warm-hearted copybooks have been posted in the waiting area of the gynecological clinic of Huashan Hospital, such as "Don’t worry, the little problems on your body will always get better slowly" and "If you don’t take good care of yourself, just say sorry to your body, and it will definitely tell you that it doesn’t matter."

The examination bed or chair in the clinic is the place where the patient’s fear concentration is the highest. In order to ease the tension, Xiaohongshu United Hospital posted the slogan "Never mind, relax" on the ceiling, "Speak out if you feel uncomfortable, and the doctor will accompany you" and other encouraging slogans.

In addition, for women’s concerns, such as "will gynecological examination hurt?" "How to check the posture?" There are also wall stickers and signs to help patients who enter the clinic for the first time quickly understand how to cooperate with doctors for examination. After the examination, "it doesn’t matter" accompanying dolls, including cute cartoon immune cells, uterus, stomach, etc., will be sent as long-term companionship to bring emotional value to patients.

It is worth mentioning that all warm-hearted and encouraging slogans come from the notes sharing of real users in Xiaohong Bookstore. In this process, Xiaohongshu realized the real concern for women from online to offline.

According to feedback from many hospitals, these improvements have been well received by many patients, and "fun" and "warm heart" are their most direct feelings. When waiting for treatment, many patients punch in and take pictures next to the floor stickers and wall stickers. A doctor admitted that she saw more patients’ smiles in the reformed clinic.

Xiaohongshu hopes that through the activity of "It doesn’t matter if there is something wrong", the public’s concept of diseases and women’s health problems can be changed, and the social value as a lifestyle platform can be highlighted.

The special ball for the Olympic football match appeared on the ＂Star of the Great Wall＂ and was branded with Chinese seal.

The special ball "Star of the Great Wall" for the 2008 Olympic Games football match was released. Photo source: State Council Office.

　　China news agency, Beijing, January 26th (Reporter Shen Chen) Adidas, a partner of Beijing Olympic Games, officially launched the "Star of the Great Wall", a game ball designed for the Beijing Olympic football match, here on the 26th, and Adidas’ 2008 Olympic football tour started.

　　The "Star of the Great Wall" was specially designed by Adidas for the Beijing Olympic Games, highlighting the elements of China. The world is dominated by red and gold with strong China characteristics, with the Great Wall pattern on the hook edge, and the word "China" inscribed by Nian Weisi, a leading soccer player in China, is printed on the sphere.

Nian Weisi, a veteran of China football, introduced the feeling of writing the word "China" on the "Star of the Great Wall" football.

　　Nian Weisi said that he has witnessed the development of China football, and it is a golden opportunity to hold the Olympic Games in Beijing. He expects China football to make a breakthrough at home. "I hope that the international players can eat well, practice well and get ready during the preparation period. By August 8, they will go into battle lightly, play the style and play the level, and win glory for the country under the influence of China."

　　China Olympic athletes Zhao Xuri, Jiang Ning, Shen Longyuan and China women’s football players Li Jie, Han Duan and Bi Yan felt the "Star of the Great Wall" at the first time. Zhao Xuri said that the surface of the "Great Wall Star" is not very smooth, and the ball speed will be faster and easier to control during the game.

Zhiji has released a roadmap for the landing of smart driving products, and will ＂technology go to sea＂ in 2024.

Guo Hui said, "The NOA public beta of the city to be opened in October means that Zhiji Automobile has completed the accumulation of other industries for many years in two years, and has continuously set a new record for the fastest mass production of intelligent driving products in the industry."

Guo Hui revealed that IM AD is preparing for the technology to go to sea, and has completed the European localization adaptability training, and the planning algorithm has adapted to the local environment and driving habits. In 2024, with the launch of the first global strategic model LS6 of Zhiji Automobile, Zhiji Automobile will share China’s intelligent driving technology with the world and rapidly expand its overseas influence.

In September, open the public beta of "NOA to high-precision map"; In October, open the "Urban NOA" public beta; In 2024, the "commuting mode" covers 100+ cities across the country; In 2025, IM AD will enter the era of Door to Door (full scene commuting) …

Guo Hui, deputy CTO of Zhiji Automobile and chief scientist of Intelligent Driving, announced the "Landing Roadmap of Intelligent Driving Products of Zhiji Automobile in the Next 3-5 Years" at the "iAd Day Intelligent Driving Conference in Tsinghua" held yesterday (August 16th).

"The NOA public beta of the city that will be opened in October means that Zhiji Automobile has completed the accumulation of head players in other industries for many years in two years (the Zhiji brand was released in 2021), and constantly refreshed the landing record of’ the fastest mass production of intelligent driving products’ in the industry." Guo Hui said, "iAd, the intelligent driver assistance system of Zhiji Automobile, not only surpasses most human drivers in safety, traffic efficiency and road game ability, but also provides users with an experience that is obviously superior to the industry standard."

According to reports, at present, Zhiji Automobile has achieved intelligent driving 3.2 times the safety of human driving. The statistical results of actual driving data show that at present, the number of collision accidents per million kilometers of IM AD is 0.6, which is far lower than the number of collision accidents per million kilometers driven by human beings, which provides a solid security guarantee for the user experience of man-machine driving. IM AD’s safety class false braking frequency is less than once per million kilometers, which is 5 times better than the industry head standard.

In terms of performance experience, IM AD’s delivery standards are equally strict, whether it is "driving performance" such as lane-changing efficiency, driving center performance, driving fluency and driving comfort, or "parking performance" such as parking space recognition ability, parking success rate and parking fluency, all of which exceed the level of the industry’s top players; The success rate of IM AD lane change is as high as 98%, the uncomfortable deceleration is only 1.3 times per thousand kilometers, and the success rate of parking is 97%. It can be called a typical "hexagonal warrior".

In Guo Hui’s view, as a new brand, behind the distance between Zhiji Automobile and its head players in two years is the underlying technical advantage of joint development and two-way empowerment with Momenta-the core competence composed of more efficient architecture, rapidly evolving algorithms and higher utilization of generative data, which will continue to drive the accelerated running of iAd’s intelligent driving evolution.

According to Cao Xudong, CEO of Momenta, iAd is the only dual-intelligent computing platform compatible with Xavier and Orin, with more efficient architecture adaptability, 90% reduction in computing power requirements and 500% improvement in model operation efficiency. Based on this, limited computing power can also achieve global visual integration; Only the scheme of "single lidar+single Orin chip" can also cover all urban scenes and meet the needs of NOA for high-precision maps.

At the same time, IM AD algorithm has faster technical evolution ability. In 2021, OneModel, BEV and Transformer technologies have been implemented, and in 2022, the first car was equipped to achieve mass production, laying the industry-leading technology base. In April 2023, Zhiji Automobile and Momenta released the industry’s first D.L.P artificial intelligence model, which solved the bottleneck problem of cognitive intelligence. The "NOA-to-high-precision map" public beta, which will be launched in September this year, will gradually realize the switching of map technology schemes and realize the uninterrupted assisted driving experience without relying on high-precision maps. On this basis, in 2024, IM AD is expected to enter the application stage of Occupancy occupying the network and realize automatic driving in most scenarios.

Guo Hui revealed that as the pinnacle of intelligent Zhiji automobile, the third model Zhiji LS6, which will be unveiled at Chengdu Auto Show, is equipped with NOA ability to go to high-precision maps. The delivery is equipped with the industry’s first "one-button scene driving" function, which solves the high-frequency pain points in certain scenes of users’ urban travel based on iAd intelligent driving technology.

At present, IM AD is preparing for the technology to go to sea, and has completed the European localization adaptability training, and the planning algorithm has adapted to the local environment and driving habits. In 2024, with the launch of the first global strategic model LS6 of Zhiji Automobile, Zhiji Automobile will share China’s intelligent driving technology with the world and rapidly expand its overseas influence.

The peak of power battery scrapping is coming! The cost of changing batteries is comparable to buying a new car？

　　Power battery replacement is expensive, and many car companies regard "battery replacement" as one of the main directions for designing pure electric vehicles in the future.

　　New energy vehicles are gradually entering thousands of households, but for some users who ate "crabs" early six or seven years ago and bought pure electric vehicles, they are now facing new troubles — — The cost of changing the battery is more expensive than the original price of buying a car! All-media reporters learned from market interviews that the current service life of automobile power batteries is mostly 5-8 years, which means that the power batteries of the first batch of new energy vehicles put into the market during 2009-2013 have entered the "retirement" period. In view of this situation, let’s see what new tricks car companies have.

　　Text, photo: Guangzhou Daily all-media reporter Deng Li

　　[Change the "electricity" scene] The battery is scrapped and the car is "scrapped"!

　　The owner, Mr. Chen, bought a Chery EQ electric car four years ago. After the subsidy, the price of the new car was about 65,000 yuan. Recently, after a heavy rain, the car was soaked in water and the battery was scrapped! After dragging it to the 4S shop, the car dealer told him that he had to replace the battery, but the cost was nearly 70,000 yuan! Mr. Chen was dumbfounded, which is thousands of dollars more expensive than buying a new pure electric car! In this regard, 4S stores also expressed helplessness: because there is no separate subsidy policy for automobile power batteries, the price of battery replacement is very expensive.

　　All-media reporters noticed that at present, because the price of "battery replacement" of many independent brands of pure electric vehicles is higher than that of buying new cars, in the event of battery failure, most car owners give up replacing batteries and directly scrap their vehicles. It is also very expensive to change batteries for imported new energy vehicles. Some people have calculated that a Tesla Model S with a price of 700,000 yuan to 800,000 yuan needs more than 300,000 yuan to replace batteries, so you can buy a BMW.

　　[Market survey]

　　The battery is guaranteed for 5~6 years, but there are constraints.

　　All-media reporters noticed that the current state requires the key components of new energy vehicles (batteries, electronic controls, motors) to provide a warranty of not less than 5 years or 100,000 kilometers. During the warranty period, the owner’s maintenance is completely free.

　　The reporter searched a number of automobile brands and found that BYD Qin currently provides "a six-year or 150,000-kilometer warranty for the whole vehicle and a lifetime warranty for the battery"; SAIC Roewe has provided E50 vehicles with 3-year and 100,000-kilometer warranties, as well as 5-year and 100,000-kilometer battery core component warranties, and some models also have battery decay warranties; BAIC provides a five-year unlimited-kilometer commitment for the battery of E150ev, and users who purchase the new EX260/EU260 before April this year can enjoy the lifetime warranty service of the battery. Generally speaking, at present, the mainstream new energy vehicle companies only guarantee the whole vehicle, and only a few manufacturers have an extra warranty for the battery for a long time. In terms of foreign automakers, Tesla has just changed the warranty terms of the Model S drive and battery pack of electric vehicles to 8 years of unlimited mileage.

　　Despite this, the cost of replacing batteries as high as 60,000 to 70,000 yuan is still in the minds of car owners. If the warranty period ends after 5~8 years, and the life of the battery just ends, then the owner will have to make a headache choice between replacing the battery or scrapping the vehicle; If the battery is within the service life and there is a problem that is not covered by the warranty (such as soaking in water), it may be necessary to break up the battery after seeing that other parts of the vehicle are still in good condition, because the high battery replacement bill is very "disgusting".

　　[Current Scheme]

　　The manufacturer’s policy encourages "replacement" in three or four years.

　　However, replacing the whole battery is not the only solution. The engineer of JAC pure electric vehicle clarified to the reporter: With the development of technology, if there is a problem with the current battery, it is no longer necessary to replace the whole battery as it was a few years ago. Now it is only necessary to replace one or several corresponding faulty batteries. The engineer told the reporter that the cost of a single battery is only a few hundred dollars, and the working hours are up to one or two thousand yuan. In general, it is cheaper than the engine maintenance of fuel vehicles.

　　However, there are many problems in the use of electric vehicles, and the high cost of batteries still inevitably becomes a resistance for many people to buy. The reporter noticed that many car companies started the "buy-back plan" to solve the problems of fast depreciation and fast battery loss of pure electric vehicles, and encouraged consumers to replace new pure electric vehicles in three or four years. For example, at the beginning of the listing of Yundu New Energy, a three-year repurchase policy was introduced at the same time, and the guaranteed price of its pure electric vehicle was 50% of the original price.

　　All-media reporters also noticed from the second-hand market that the current depreciation of second-hand new energy vehicles is faster than that of ordinary fuel vehicles. For example, in 2013-2014, the price of Beiqi E150EV in the second-hand market ranged from 20,000 to 40,000 yuan. After the updated Beiqi EX360 went on the market, manufacturers also complied with the repurchase and replacement policy. As long as the car condition of the old pure electric vehicle meets the official standards, it can offset the purchase price of 39,800 yuan, which is much more cost-effective than direct scrapping. In doing so, manufacturers not only encourage consumers to trade in old ones for new ones, but also help consumers avoid the embarrassment of finding out that the battery life has ended after six or seven years of use and being forced to scrap their vehicles.

　　[Car enterprise goal]

　　Load a detachable battery

　　Perhaps it is precisely because the high cost of batteries has aroused the concerns of users, and many car companies regard "battery replacement" as one of the main directions for designing pure electric vehicles in the future. It only takes three to five minutes, and a "blood tank is empty" battery is directly removed and replaced with a new battery with full charge. Although the power exchange technology has not been verified by a large number of landing operations, this idea is favored by many new energy vehicle companies.

　　Traditional car companies, such as BAIC New Energy, have taken the lead in distributing in several cities across the country since last year to carry out the service of "changing power stations". After the taxi industry has achieved good response, this year, the "changing power" model has been extended to the field of pure electric private cars in Beijing. As for the new car-making enterprises, it has been included in the research and development category. Previously, Tesla had announced a 15-minute power exchange technology; Weilai, the representative of China’s new car manufacturers, plans to build more than 1,100 power stations nationwide in 2020, hoping to let car owners realize "changing electricity within 3 kilometers" in the central areas of first-tier cities such as Beishangguangshen and Shenzhen; Another new car manufacturer, Chehejia’s first SEV, its biggest highlight is the use of detachable batteries, which is also the official claim that they do not rely on the capital of charging piles.

　　China new energy vehicles ushered in the first peak of power battery scrapping.

　　In 2009, China officially launched the demonstration and promotion of "10 cities and 1000 vehicles" new energy vehicles.

　　From 2012 to 2014, demonstration applications were conducted in the north, Guangzhou and Shenzhen, and new energy vehicles entered the era of private consumption.

　　In 2015, the sales volume of new energy vehicles in China was 331,000, of which 247,000 were pure electric vehicles, ranking first in the world.

　　In 2017, the sales volume of new energy vehicles in China reached 777,000, ranking first in the world for three consecutive years.

　　In 2018, the first batch of new energy vehicle battery systems will enter the "seven-year itch" elimination period, which will usher in the first peak of power battery scrapping.

　　In recent years, the relevant state departments have paid extra attention to the market guidance of battery recycling. At the same time, the data of the Ministry of Industry and Information Technology shows that the first peak of power battery scrapping will be ushered in 2018. Gao Yunhu, director of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, pointed out that it is necessary to accelerate the recycling of power batteries for new energy vehicles and implement the formulation and implementation of pilot programs. On August 1st, the Interim Measures for the Management of Recycle and Utilization of Power Batteries for New Energy Vehicles was promulgated and implemented. In September, the Ministry of Industry and Information Technology issued the List of Qualified Enterprises (First Batch).
