　　Intersection news, with the successful launch of the Beidou-3 GEO-3 satellite, our country’s Beidou satellite navigation system construction project has been successfully completed, the star array has been listed, and the global "Skynet" has been successfully woven. What changes will the "Beidou-3" bring to our lives in the future? After more than 30 years of practice and exploration, why is our country so persistent in the construction of the "Beidou" system? The reporter interviewed Professor Wen Xin and Professor Kang Guohua from the School of Aeronautics and Astronautics of Nanjing University of Aeronautics and Astronautics to explore the way forward for Beidou together.

　　You’ve already used Beidou, but you may not know it.

　　Many people know that our country launched the Beidou satellite, but they do not know that Beidou has long been available to the people and open to the world.

　　If you pay attention, it is not difficult to find that your smartphone can always accurately tell the time, almost not like a watch, occasionally "going fast" or "going slow", and it is the Beidou satellite navigation system that helps you "check the watch".

　　Kang Guohua, a professor at the School of Astronautics at Nanjing University of Aeronautics and Astronautics, told reporters that "Beidou" is not just a satellite launched into the sky, but a huge system project. Seemingly out of reach, it is actually closely related to our lives. "Since the 1980s, the whole world has been using the GPS of the United States. With the Beidou system, the absolute dominance of GPS in the field of global satellite positioning has been challenged, and now most of our mobile phones have begun to use the Beidou navigation system."

　　He took out his mobile phone and showed the reporter the satellite zenith map displayed by the mobile APP. The picture shows the movement of the satellites of the four major satellite navigation systems in the world on the local zenith. They are the Global Navigation and Positioning System (GPS) of the United States, the GLONASS system of Russia, the Galileo system of the European Union, and the Beidou system of China. "Among them, the color satellites that can receive signals are in orbit, while the black and white ones are temporarily unable to receive signals."

　　Each Beidou satellite weighs 850KG, has a payload weight of 300Kg, and carries three functions – positioning, timing and short message. Positioning is the foundation of navigation, and navigation is the application of positioning, Kang Guohua said. Positioning is "telling you where you are" and navigation is "telling you how to go from where you are now to where you want to go."

　　Timing, as the name implies, is to "give the exact time". For some instruments and equipment, it is to calibrate the time. As long as the Beidou timing function is used, even if it is distributed in different parts of the world, the time can still be "synchronized". Kang Guohua told reporters that time synchronization is a national security guarantee, such as high-speed rail, power grid, computer network communication, etc., all need time synchronization. For example, relying on the precise positioning of Beidou, the high-speed rail brakes from 350 kilometers per hour to parking, and the final stop error can be controlled within 10 centimeters.

　　Short messages are a unique feature of China’s Beidou. Unlike GPS receivers, which can only receive satellite signals in one direction, Beidou receivers can not only achieve positioning, but also send and receive text messages similar to mobile phones, and transmit two-way text messages through satellites.

　　During the Wenchuan earthquake rescue in 2008, the ground communication facilities were seriously damaged and even paralyzed. The rescue troops used Beidou short messages to send the first message from the disaster area, accurately reporting the disaster situation and the location of the disaster to the disaster relief and rescue headquarters, which played a huge role. At that time, the accuracy of "Beidou No. 1" was actually not high enough. Its two-way communication function had shown great power and saved countless lives.

　　"The stars move", and a "Skynet" has been woven for more than 20 years.

　　Behind the dream of "Big Dipper" is the relay struggle of several generations, from nothing to something, from weak to strong, the "Big Dipper" star is increasingly dazzling.

　　Professor Wen Xin of the School of Aeronautics and Astronautics of Nanjing University of Aeronautics and Astronautics told reporters that people’s ideas about the Beidou satellite navigation system can be traced back to 1983. Academician Chen Fangyun, a famous aerospace expert, first proposed the concept and idea of dual satellite positioning.

　　"The chief designer who set a three-step development plan for the Beidou satellite navigation system is Sun Jiadong, the father of our country’s’two bombs and one star ‘." Wen Xin introduced that in 1994 our country launched the construction of the Beidou satellite navigation test system, which is the "Beidou generation". The second step was to start the construction of the Beidou satellite navigation system in 2004. In 2012, a regional passive service capacity was formed. And the third step was this year, the formation of a global passive service capacity. "From 2007 to 2010, a network of satellites was launched continuously, weaving an information network in the sky."

　　Since the "Beidou Generation" uses a dual-star positioning method, the "Beidou Generation" has a lot of room for improvement in positioning accuracy, timing accuracy, service area, etc., especially the problem of large signal transmission delay. "For example, the positioning accuracy of the" Beidou Generation "is 20 meters, which means that the" Beidou Generation "cannot" see "two objects less than 20 meters away from the distant space and calculate their position difference.

　　Kang Guohua said that at present, our mobile phones are generally integrated with satellite systems from two, three or even four countries. "Why don’t we use China’s Beidou system alone? Because the Beidou-2 system focuses on the Asia-Pacific region, the service in other parts of the world is not very stable."

　　Kang Guohua compared the multiple launches of Beidou satellites to "puzzles". Beidou-1 is an experimental satellite, with only four satellites, which are only over our country and have all been decommissioned. Later, Beidou-2 is a regional networking satellite, covering a total of 20 satellites in the Asia-Pacific region. The space segment of the "Beidou-3" satellite navigation system consists of 27 medium-earth orbit satellites, 5 synchronous orbit satellites, and 3 inclined synchronous orbit satellites, totaling 35 satellites.

　　From the first satellite of Beidou-2, our country has launched 54 Beidou navigation satellites, which have been officially put into the network since June. The last network satellite launched on June 23 is the 55th in the entire Beidou satellite navigation system.

　　Kang Guohua said that although this time we launched the last star in the puzzle, in fact, the satellites in the Beidou system have been changing. "Each satellite has a lifespan, and it needs to be retired in an average of 8-10 years. Since the construction of the third generation of Beidou, many satellites have been retired and added. The significance of the 55th star is to make the Beidou system truly the Beidou of the world, and it can be located anywhere on earth."

　　The brightest Chinese star, let the stars in the sky "refer to the Big Dipper"

　　What is the significance of the Chinese astronauts’ dedication to the "Beidou" satellite?

　　As an important weapon of the country, Beidou is a major space infrastructure in our country. The goal of building our country’s space-time reference network and navigation information network is an important support for my great power status and strategic interests. "It can be said that the sooner the construction is made, the more strategic advantage it will have." Kang Guohua gave an example. "Satellite positioning requires the transmission of radio waves at specific frequency points from the sky to the ground. Since only specific frequency points have the least attenuation during the process of electromagnetic waves penetrating the atmosphere, these frequency points have become important strategic resources." According to the current ITU’s "first-served" rule for frequency point allocation, the United States has chosen the best frequency band because it was the first to build GPS.

　　The competition in satellite navigation is not only the competition of the technical system, but also the competition of constellations and signals. China, Europe, and the United States have gone through years of coordination work on satellite frequency and orbital position issues, and even "open and secret wars", which are full of "games" of aerospace powers.

　　The Beidou-2 navigation system has experienced such a pressing time. According to the relevant regulations of the ITU, the Beidou-2 navigation system must complete the satellite navigation signal in orbit and broadcast to the ground within seven years. Otherwise, the priority right to use the navigation frequency will be cancelled. It is necessary to reapply for the frequency and carry out relevant international coordination. As a result, our country will lose the best opportunity to develop a global satellite navigation system.

　　Facing the urgent development task, Chen Zhonggui, an alumnus of Nanjing University of Aeronautics and Astronautics and then the deputy chief designer of the Beidou-2 satellite, led the party commando team to improve the integrated test verification method, and fought for 8 months with "5 + 2" a week and "white + black" every day. On April 16, 2007, two days after the successful launch, Beijing received a clear signal from the flight test satellite. At this time, there were less than 4 hours left before the space frequency failure – it was this feat that effectively protected the frequency resources of our country’s satellite navigation system and opened the prelude to the construction of the Beidou regional navigation system.

　　"Today, the successful networking of the Beidou-3 global satellite navigation system marks that our country has the" capital "of PK with the strength of the US GPS navigation system in the field of satellite navigation systems. Beidou is not only a national project, but also a national project. ‘Beidou’ has multiple’firsts’." Wen Xin listed that the Beidou satellite navigation system has adopted the hybrid constellation system of three orbits (GEO, IGSO, MEO) for the first time; it has reached the requirement of 100% localization of components for the first time; and it has proposed cooperation and compatibility for the first time… These all make China’s aerospace and satellite monitoring technology more confident in the world.

　　For example, the on-board atomic clock, which is the "heart" of a navigation satellite, was once a technological blank in China. There was a time difference between radio wave transmission and reception, and the time difference multiplied by the speed of light was the distance. As long as the error was one second, the distance would be 300,000 kilometers. During the development of Beidou-2, a Swiss company was introduced, but later the European Union required the company to provide atomic clocks that were an order of magnitude less accurate than the "Galileo" navigation system, which made Chen Zhonggui and the design team more deeply realize that "key core technologies cannot be bought, or they cannot be bought, or they cannot be bought."

　　Today, our country has conquered the key technologies of rubidium atomic clock and hydrogen atomic clock, and used these two atomic clocks on the Beidou navigation satellite to achieve the establishment of time benchmarks. Among them, the on-board rubidium atomic clock has achieved 100% localization of components, and the current accuracy can reach 3 million The error is only 1 second, and the passive on-board hydrogen atomic clock has an error of 1 second in 10 million years.

　　At present, the Beidou-3 satellite has formed a distinct Beidou feature in terms of positioning services, wide-area enhancement services, global short message services, search and rescue services, etc., and has achieved partial leadership in foreign technology in terms of system signal performance, system transmission and ranging performance, on-board atomic clock performance, and localization of key products and components. In the open class on ideological and political affairs of Nanjing University of Aeronautics and Astronautics, Chen Zhonggui confidently pointed out that "the core of the Beidou-3 system is to serve the world with higher accuracy and higher performance," so that China’s Beidou is also the world’s Beidou! "

　　The era of "Beidou +" has begun, and it must be easy to use both in the sky and on the ground

　　After the Beidou global network, the speed of integrating the Beidou system with positioning, timing and short message services into the lives of ordinary people will accelerate. "Beidou +" life will come faster.

　　"It will become an infrastructure like the water grid and the power grid, and daily life can no longer be separated from it. If you order a takeaway or order a ride-hailing car, you need to use satellite positioning to determine your current location." Kang Guohua said, but then Beidou has to solve various problems such as reliability, accuracy and stability.

　　"Beidou’s biggest problem now is application promotion." Kang Guohua said that after all, GPS has been developed more than 20 years earlier than us, and users have become sticky and inertial. Take mobile phones as an example, replacing GPS chips with Beidou chips will increase a lot of external costs, and merchants have no incentive to replace them. Therefore, in some mature areas of GPS applications, replacing Beidou often encounters relatively large resistance. But the more people use Beidou, the lower the cost will be, and the faster the iterative improvement speed will be, forming positive feedback.

　　The research on "low-orbit satellite navigation enhancement" currently led by Professor Kang Guohua is related to the promotion and application of Beidou. "If we compare the Beidou system to a highway-like backbone network, it can provide positioning accuracy better than 10 meters; then our work is similar to building’provincial roads’, and further improve the accuracy on the basis of this backbone network."

　　As an example, Kang Guohua said that when you shuttle between city buildings, due to the "canyon" effect formed by the buildings, you can see the sky is very small, so the signal received by the satellite is small and weak. The low-orbit navigation enhancement system is to add another layer of low-orbit constellation below the Beidou constellation, and use the navigation enhancement system on the low-orbit satellite to achieve Beidou signal enhancement and broadcasting, thereby improving the strength of the signal and upgrading the original Beidou road-level positioning to lane-level positioning. Before we could know where people were, now I have to know whether you took your left foot or your right foot. "Kang Guohua said. Now Japan has a Quasi-Zenith satellite that does something similar, but they do it with GPS, and our team did it with our own Beidou.

　　In the future, the Beidou satellite navigation system will have a wide range of applications in land, sea, aerospace, mass consumption and other fields. "For example, in marine fisheries, the navigation of ships and the establishment of an integrated fishery information service network are inseparable from the positioning signal of the Beidou system." Wen Xin said that in the field of transportation, the application of advanced satellite navigation technology is an important means to realize the informatization and modernization of transportation, and is of great significance to the establishment of a smooth, efficient, safe and green modern transportation system. "

　　The reporter learned that the Beidou system has begun to be applied in many fields in our country. For example, the hydrological monitoring system based on the Beidou system has realized the real-time transmission of hydrological and water regime information, greatly improving the accuracy of rain, water regime, drought and disaster information collection and the timeliness of transmission. It has been widely used in southern Shaanxi, the Yangtze River Basin and the Yellow River Basin in our country, and the number of users has reached more than 4,000. "In the field of weather forecasting, after many years of meteorological digital message transmission application experiments, a series of meteorological forecast-type Beidou end point equipment and system application solutions developed by scientific researchers have solved the automatic transmission and collection of weather station digital messages and the visual display function of weather station map distribution by the National Meteorological Administration and meteorological centers in various cities. At present, the end point of Beidou application in the meteorological field has reached thousands of units. "

　　Microlink – "Beidou No. 3" Chief Engineer "Nanhangzao"

　　"Beidou-3" also has a cordial connection with Jiangsu. Its chief designer, Chen Zhonggui, is an 86-level alumnus of Nanjing University of Aeronautics and Astronautics.

　　"Look up at the starry sky, hold up the ambition to explore the universe. Work hard to realize the dream of a space power." On this year’s fifth "China Space Day" and the 50th anniversary of the successful launch of the "Dongfanghong No. 1" satellite, Chen Zhonggui sent an affectionate message to the students of his alma mater.

　　Chen Zhonggui has worked in the Aerospace Academy for 31 years after graduation, of which 20 years have been engaged in work related to Beidou. Beidou satellite navigation system has grown from nothing, from weak to strong, from regional to global, he has witnessed 80,000 Beidou people working day and night, painstaking research and dedication.

　　In December 2018, Chen Zhonggui returned to the campus of China Southern Airlines and brought a shocking open class on the ideology and politics of the alumni chief teacher "Beidou Navigation Satellite" to the students. Chen Zhonggui, who originally studied mining machinery as an undergraduate, quit his job after working for a few years out of yearning for his aerospace dream and chose to apply for the mathematical mechanics major of Nanjing Institute of Aeronautics and Astronautics (the predecessor of Nanjing University of Aeronautics and Astronautics), under the tutelage of Professor Zhu Ming, who is engaged in multi-body dynamics research.

　　"The study style of China Southern Airlines is very strict, especially the requirements of the professional basic courses are particularly high, and the exams are not ambiguous." This is what Chen Zhonggui remembered most when he was studying in graduate school. He still remembers the automatic control of this course, "The exam results are not satisfactory, and the teacher will talk to the students to help the students analyze the reasons, and draw inferences from one another." It is with such a rigorous study style and dedicated professional teachers that Chen Zhonggui made up for the gap in professional foundation in time during his graduate school, laying the foundation for the later work development.

　　Under the guidance of Mr. Zhu Ming, Chen Zhonggui aimed his graduate thesis at the new modeling theory of multi-body dynamics and the development of analytical software. During the writing of his graduate thesis, he had more opportunities to come into contact with the field of aerospace, and at that time, aerospace was most lacking in professionals engaged in basic disciplines such as dynamics and heat. It was this opportunity that Chen Zhonggui "naturally" formed a tacit connection with aerospace, and after graduation, he resolutely chose the Fifth Academy of Aerospace, a field he had pursued and loved.

　　In the open class for the students of China Southern Airlines, Chen Zhonggui comprehensively reviewed the development process of our country’s Beidou satellite navigation from No. 1 to No. 3, and systematically described the technical evolution and major innovation achievements of our country in the field of satellite navigation systems. Now the Beidou satellite navigation system has achieved 100% localization of stand-alone products that make up satellites, and all core components have been localized. It has become the fourth mature satellite navigation system after the US GPS, the Russian GLONASS system, and the European Galileo system.

　　Compared with Beidou-2, Beidou-3 requires more complete functions, more indicators, and higher reliability. How to achieve a leap in system performance in a short period of time is a severe challenge for the Beidou-3 demonstration team. Chen Zhonggui led the development team to check the data, build the standard, build the model, make the layout, and compile the plan, and finally formed a technical demonstration report that meets the different needs of all parties.

　　Looking to the future, he hopes to build a Beidou satellite navigation system that serves the world, is focused, distinctive, locally leading, and has a smooth transition, forming a more ubiquitous, more integrated, and more intelligent benchmark space-time system. Making China’s Beidou also the Beidou of the world is his unswerving career goal for satellite navigation, and it is also a solemn oath to our country’s aerospace power.

　　Intersection reporter, Yang Pinping

　　Zhongxin Jingwei Client, September 13th (Fu Yumei) Recently, China Automobile Finance and Hedge Rate Research Committee released "2019 China Automobile Hedge Rate Report" (hereinafter referred to as "Report"), which showed that the average hedging rate of mainstream new energy vehicles in the past three years was only 32.31%, much lower than that of traditional fuel vehicles. Judging from the one-year preservation rate of pure electric vehicles, except for Tesla, which is over 60%, the preservation rates of other models are generally low.

　　This data has attracted the concern of some new energy owners: a new energy vehicle with a starting time of more than 100,000 yuan is only worth tens of thousands of yuan a year? The current situation of low hedging rate has once again attracted the attention of the new energy used car market inside and outside the industry.

　　In the slogan of a second-hand trading market in Beijing, Xin Jingwei Fu Yumei took a photo.

　　Low hedging rate leads to the obstruction of profit space.

　　The Report takes the cruising range of 300 kilometers as the dividing line, and counts the ranking of the preservation rate of one-year-old pure electric vehicles with cruising range less than 300 kilometers and more than 300 kilometers respectively.

　　According to the "Report", among the top ten pure electric vehicles with a maximum cruising range of not less than 300 kilometers and a one-year-old car, Tesla MODEL X and MODEL S rank in the top two, with preservation rates of 68.09% and 64.75% respectively; Weilai ES8 ranked third with a hedging rate of 47.89%. Geely Emgrand sedan and Chang ‘an Yidong New Energy ranked the last two, with the preservation rates of 38.03% and 36.82 respectively.

　　Among the top ten pure electric vehicles with a cruising range of less than 300 kilometers and a one-year-old car, BMW i3 ranks first with a value-preserving rate of 46.55%. Beiqi New Energy EU260 maintains a value of 30.91%, ranking second; The preservation rate of the other eight models is below 30%.

　　Compared with fuel vehicles, the vehicle maintenance rate within three years is still basically maintained at around 59%-75%.

　　Mr. Sun, a new energy used car dealer in Beijing, told the Zhongxin Jingwei client that after a year of using a new energy vehicle, most of them have only one-third of the residual value, which is equivalent to a new energy vehicle bought at an original price of more than 100,000 yuan. Only tens of thousands of pieces can be sold when it is sold. "Many new energy owners can’t accept it when they come to consult for the first time. I don’t believe that the car that I have only been driving for one year has depreciated so much."

　　Mr. Sun pointed out that the low maintenance rate of new energy used cars also led to its profit margin being much lower than that of fuel vehicles. "The profit of new energy used cars generally does not exceed 3,000 yuan, and the circulation is not very fast. In contrast, the profit of a 5-7-year-old fuel vehicle is higher than that of a 1-year-old new energy vehicle. But if you switch to a new energy vehicle a few years ago, you can’t sell it now. "

　　Due to low profits and many restrictions, the recognition of new energy used cars in the market is not strong. During the visit to the used car trading market, the Sino-Singapore Jingwei client communicated with several dealers. They said that the business of new energy used cars is not good because of the low rate of preservation. One of the dealers still has a backlog of a 2017 JAC iEV6E recovered three months ago. The original price of the car purchased with tax was close to 140,000, and now the price is only 35,000 yuan. He said that if you want to collect new energy used cars, you must be no more than three years old. "And it is best to be the top brands such as Tesla, BAIC and BYD, otherwise it is very likely to become ‘ Trading at a loss ’ 。”

　　Short battery life is the "culprit"?

　　In addition to the offline trading market, the Sino-Singapore Jingwei client also found that the low-priced sale of new energy used cars has become a common phenomenon when consulting some online trading platforms for used cars. Some old models three years ago, the price is even far lower than 1/3 of the original price. So, what is the reason for such a low rate of preservation of new energy used cars?

　　Wang Yongqing, head of used car inspection technology of Youxin, told the client of Zhongxin Jingwei: "The first reason for this phenomenon is that the early electric vehicles had a short cruising range and could not even meet the daily driving needs after the batteries aged. In addition, the after-sales maintenance service of new energy vehicles has not been fully improved, and the complaint rate is high. Once some manufacturers’ vehicles are transferred, they no longer enjoy the original warranty. "

　　Jia Xinguang, executive director of china automobile dealers association, also said that compared with fuel vehicles, the low maintenance rate of new energy used cars mainly comes from their battery problems. "Even if the engine works for 3 to 5 years, the battery is facing the problem of easy aging."

　　According to the 2018 China New Energy Vehicle Industry Report released by iResearch, 40% of the cost of new energy vehicles is concentrated on power batteries. According to many new energy vehicle owners, because there is no subsidy, the cost of replacing the power battery is sometimes even similar to buying a new car. Mr. Sun pointed out that under normal circumstances, the battery life of new energy vehicles is between 4 and 6 years, and the service life of some poor quality batteries is shorter. The cost of replacing batteries determines that it cannot raise the price in the market.

　　In addition, many people in the industry report that compared with fuel vehicles, new energy used cars lack a perfect evaluation system, which is indispensable in the pricing process of used cars. Wang Xiaoyu, co-founder and vice-president of Cheduoduo Group, pointed out at the 2019 Summit on User Value and Maintenance Rate of New Energy Vehicles that the evaluation system of new energy used cars is still not perfect, especially the problem of difficult battery evaluation, which makes it face great challenges.

　　It is understood that with the development demand of the new energy used car market, many platforms have begun to explore corresponding solutions. For example, the second-hand car platform of Guazi recently announced that it has started the evaluation and research on the battery part of new energy vehicles, and established a "car with many brains" to evaluate and price used cars according to the energy consumption rate, driving range and charging efficiency of new energy vehicles. The Youxin used car platform has also begun to digitize vehicle information by means of video detection and VR, and visually present the quality of batteries and vehicle sources.

　　The speed of upgrading is fast, and the data of hedging rate remains to be seen.

　　It is worth noting that the limitation of the market size of the new energy used car itself makes the current situation of its hedging rate face uncertainty. Ding Shaoguang, head of melon seeds used car brand, told Zhongxin Jingwei client that the proportion of new energy vehicles is still too small compared with fuel vehicles, so the relative market size of new energy used cars is not large.

　　Yan Jinghui, an expert from the china automobile dealers association Expert Committee, also pointed out that the current data on the hedge ratio remains to be seen because the number of new energy vehicles entering the used car market is limited.

　　Yan Jinghui said that most of the used cars entering the new energy market are old cars with a cruising range of less than 200 kilometers. Because of the fast replacement frequency of new energy vehicles, few car owners are willing to accept used cars with too much performance difference.

　　Wang Yongqing also stressed that the second-hand cars with new energy are easy to fall behind in technology, while consumers are relatively more willing to buy models with more advanced technology.

　　In July this year, less than four months before the release of the 2019 Tucki G3, Xpeng Motors released the 2020 Tucki G3. In contrast, the 2020 driving range has increased by more than 100 kilometers, but the price is not much different. This phenomenon angered the old car owners, led to many rights protection incidents, and also made Xpeng Motors encounter the biggest crisis since its listing.

　　Yan Jinghui said that the most direct performance of new energy vehicles to launch new models is the increase in cruising range, and the old cars are easily eliminated by the market, which is one of the reasons for its serious depreciation problem.

　　Expert: The problem of hedging rate may be improved in the future.

　　In view of the market pain points faced by new energy used cars, the Report proposes that in addition to Tesla’s brand effect, businesses such as "value-preserving repurchase" and manufacturer-certified used cars provided by manufacturers have realized effective strategies to increase the channel and value-preserving rate, which plays an important role in improving the value-preserving rate of electric vehicles.

　　The owner of a new energy source in Beijing told the Zhongxin Jingwei client that he expected manufacturers and 4S stores to provide corresponding preferential services, such as replacement services, rather than directly reselling them in the second-hand market at low prices.

　　The Zhongxin Jingwei client consulted a 4S shop with a domestic new energy vehicle with an original price of 140,000 yuan, two years’ purchase and a cruising range of 200 kilometers. The staff said that the replacement price was about 30,000 yuan, but an additional subsidy of 5,000 yuan could be provided. It is understood that many 4S stores provide subsidies ranging from several thousand yuan to 10 thousand yuan for replacement services, and support cross-brand car replacement.

　　Car companies are also introducing corresponding measures. A few days ago, Weimar released a user care plan, hoping to alleviate users’ anxiety about battery performance and preservation rate through services such as vehicle replacement and upgrading, lifetime warranty of power battery, vehicle replacement and transfer.

　　"Changing electricity, repurchasing, and sharing, these measures may improve the current low value-added rate of new energy used cars." Jia Xinguang said. He also stressed that in order to improve the preservation rate of new energy vehicles, it is still necessary to focus on its biggest pain point, that is, work hard on power batteries.

　　Many people are optimistic about the future of the new energy used car market. Yan Jinghui said that with the gradual stabilization of the quality of new energy vehicles, new energy vehicles with a cruising range of more than 250 have gradually entered the used car market, and the supporting facilities such as charging piles have become increasingly perfect. With the efforts of all parties, the problem of the value preservation rate of new energy used cars will gradually be improved.

　　Mr. Sun also told the Zhongxin Jingwei client that there are not many dealers who specialize in new energy used car business like him in the Beijing used car trading market. "There may not be one in hundreds." However, he believes that under the situation that the used car market of fuel vehicles is becoming increasingly saturated, new energy vehicles that gradually enter the mainstream vision will become the future trend. He hopes to pass the current "bottleneck period" as soon as possible and seize the market share of new energy used cars before the trend comes.

　　Wang Yongqing said that at present, new energy vehicles are in a high-speed development stage, and practitioners in the new energy used car industry need to keep up with the development of the industry, respond in time, do a good job in technical iteration, and meet the needs of consumers in a series of after-sales services such as maintenance.

For SAIC, Zhiji Automobile is a proper "prince", and it comes with its own aura and is highly anticipated.

Investment from SAIC, Ali and Zhangjiang Hi-Tech recently reached RMB 3 billion, with a valuation of RMB 30 billion.

At the presentation of SAIC’s 2022 semi-annual report, Zhiji was a "major strategic innovation project" of SAIC, and it was also mentioned in the semi-annual report that Zhiji Automobile was an important starting point for SAIC’s "upward development of independent vehicles".

At the beginning of the year, during the worst epidemic in Shanghai, SAIC tried its best to allocate resources to ensure that key new products such as Zhiji L7 went on sale. Zhiji Automobile has also been emphasizing the background of SAIC.

However, the sales of Zhiji L7 are not satisfactory. Since the delivery in late June, the delivery volume is not good. According to the data disclosed by the Association, in September, Zhiji L7 sold 1,019 units, and in July and August, it sold 816 units and 1,007 units respectively.

In the past, there were competitors such as Weilai, and behind them, there was a "direct biography" brother Feifan Automobile, which was about to go public. At that time, it would also seize the resources of SAIC. Can Zhiji afford to be the prince of SAIC?

In January, it sold for 1000 yuan, but it was difficult for the prince to win public support.

In September, the auto market improved.

Recently, according to the latest automobile sales data released by China Automobile Industry Association, the automobile sales volume in September was 2.61 million units, up 9.5% month-on-month and 25.7% year-on-year, maintaining a high-speed growth momentum. Among them, the sales volume of new energy vehicles reached 708,000, a year-on-year increase of 93.9%, and the market share reached 27.1%.　

Tesla’s ModelY sold 51,802 units in September, holding the top spot. The top 30 models have sold more than 5,000 vehicles per month. Among the new forces making cars, Ideal L9 sold 10,123 units. In the pure electric vehicle market with a price exceeding 400,000 yuan, the sales volume of Weilai ET7 in September was 2,928.

"ZhiJi monthly sales of one thousand, must be failed. Although it is said to be a high-end positioning of around 400,000, it will take thousands of units a month, which is similar. " Mr. Zhou, an insider of the car circle, said.

The sales volume is bleak. Besides the brand has just started and its popularity is not high, Zhiji’s investment in channel construction is not strong, which is also an influencing factor.

According to the statistics of Lujiu Business Review, Zhiji has about 40 experience centers and about 35 delivery centers in China. This kind of coverage network is somewhat inadequate.

Taking Beijing as an example, Lu Jiu’s business review learned that Zhiji has only four experience centers in Beijing. Among them, Beitou Shopping Garden Store has just opened on National Day. In contrast, LI has 18 stores in Beijing. Weilai Automobile has 21 stores in Beijing.

Not only that, in terms of distribution channels, Zhiji is also relying on SAIC. During the visit, Lu Jiu’s business review found that several Zhiji sales points in Beijing were made by traditional 4S Buick dealers.

For example, Wangfujing APM store, Zhiji automobile and Buick dealer Gadalai cooperate. Take the mode that Zhizhi pays to rent the storefront, and the dealer hires people to be responsible for the management.

This is somewhat similar to Huawei’s channel vendors, but slightly different. The M5 and M7 sample cars displayed in Huawei Experience Store are all purchased by the store owner himself. The sample cars in Zhiji’s store are directly provided by Zhiji, and dealers do not need to pay for them themselves.

Users book cars online, dealers take sales commissions, and deduct employees’ sales commission and marketing expenses, which is their own profits.

"Zhiji is like this, in order to reduce the pressure on dealers. If you pull the dealer alone, the cost will be invested. If the sales volume does not come up, it will be very troublesome later. " Mr. Zhou said.

When some car companies push new products, they will "apportion" the dealers, and at the same time, they will take some newly pushed models while entering those models that sell well. Mr. Zhou believes that Zhiji’s approach is somewhat similar to this method.

In addition, Zhiji is also conservative in brand investment. "SAIC is a state-owned enterprise, and its budget is very strict, so there are fewer advertisements." The sales staff of Zhongguancun exhibition shop told Lu Jiu’s business review.

If the sales volume does not come up, the turnover of sales staff will be great. "The basic salary of sales is 4,000 yuan. We can probably get 800-1000 yuan when we sell a car. Especially in the past few months, sales have not yet started. Some salespeople can’t sell cars, so they get a basic salary. The pressure in Beijing is great. He left without moving." The sales of Liu, who led the exhibition at Heshenghui, said.

In view of the current sales situation, what further measures does Zhiji have? Lu Jiu’s business review asked Zhiji’s official about this, but as of the time of publication, he didn’t get a reply.

The prince’s tough battle is not easy to fight.

As the "No.1 Project" of SAIC, Zhiji Automobile has high hopes. SAIC hopes that the Prince will fight hard and attack the independent luxury car market that the Group has not been able to win.

SAIC defines Zhiji as a high-end luxury brand. In the company’s 2021 annual financial report, there is such a description: through the listing of new products such as Zhiji, SAIC Audi and Cadillac, the product camp of luxury brands is further strengthened.

In terms of vehicle size, price and configuration, the target of Zhiji L7 is Weilai ET7. The models with two configurations of Zhiji L7 are priced at 368,800 and 408,800 respectively; The price of Weilai ET7 is about 450,000 to 530,000.

"Wisdom has more control and performance. We call this car the control involution king, which is a bit niche and biased towards those who like to play with cars. " A sales person surnamed Ren told Lu Jiu Business Review.

"We are cheaper than ET7. ET7 is mainly expensive in its service, because they have power exchange service. These are all costs, which will ultimately be reflected in the price of the car." He said that at present, Zhiji L7 has no power exchange service, so the price is cheaper than Weilai.

Compared with Zhiji, Weilai started early, has a strong brand influence, and relies on the unique positioning of "car as a service" to form a strong user stickiness.

In terms of sales volume, there is also a considerable gap between Zhiji L7 and Weilai ET7. Weilai ET7 sold 2,928 units in September and 4,349 units in June.

The prices of two products of Zhiji L7 have reached the price range of BBA. According to public information, only Weilai can occupy a place in the market segment of 350,000-400,000 yuan.

Hi-Tech Intelligent Automobile Research Institute believes that this road of Zhiji is very difficult. The top matching of Zhiji L7 with a price of 408,800 yuan is the model range of BBA, and the general effect will not be very good if the top matching is used to play the low matching of joint venture brands.

Tamia Liu, CEO of Zhiji Automobile, once said: "It is miserable and helpless for users who spend more than 400,000 plus tax close to 500,000 to buy BBA."

Today’s Zhiji car, the differentiated competition has not been shown, but the price and positioning have kept up. This kind of unsynchronization has the most intuitive appearance in sales volume. Although relying heavily on the brand and production and supply resources of SAIC, as an independent luxury brand, Zhiji lacks sufficient persuasion.

Can brothers still sit still when they are competing for the crown prince?

In the past, there were independent brands such as Weilai and many joint venture brands. Behind them, Zhiji Automobile also faced the resource competition of another brother, Feifan Automobile.

Feifan Automobile is an R brand wholly owned and operated by SAIC and its employees, and it is also a brand within SAIC. In contrast, Feifan car is more like a "prince" than Zhiji.

In the planning map of SAIC, it is Zhiji Automobile and Feifan Automobile that promote the development of independent brands. Moreover, Feifan Automobile, like Zhiji, is also a "major strategic innovation project" of SAIC.

Tamia Liu, co-CEO of Zhiji Automobile, has served as an important manager in various positions of SAIC, and has served as product manager, director of market operation department, director of product planning and deputy general manager of quality and economic operation department.

Wu Bing, CEO of Feifan Automobile, has 20 years working experience in SAIC. According to public information, Wu Bing has successively held important positions in several subsidiaries of SAIC-GM, Shanghai Automotive Group Insurance Sales Co., Ltd. and Xiangdao Travel.

Backed by SAIC and endorsed by SAIC is the basic strategy of Zhizhi. In Zhiji’s sales store, the words "Ali makes cars, SAIC quality" are particularly eye-catching.

In manufacturing, Zhiji also relies on SAIC platform. "SAIC has many resources, including the rear wheel steering technology of the car, the design of the chassis, chips and hardware equipment, all relying on SAIC’s supply chain." Ren surnamed sales of Zhongguancun exhibition shop said.

On September 22nd, SAIC announced that it will jointly invest with China Petrochemical, China Petroleum and Contemporary Amperex Technology Co., Limited to establish Shanghai Jieneng Zhidian New Energy Technology Co., Ltd., and will build charging piles at 50,000 gas stations nationwide.

Zhiji characterized this news as good for car owners, and all sales points made publicity signs: "Zhiji’s energy replenishment system will be expanded again, and relying on Jieneng Zhidian, a subsidiary of SAIC, we will fully promote the strong upgrade of the charging network."

Flying every car is the same strategy.

Wu Bing, CEO of Feifan Automobile, was also deliberately highlighting the resources of SAIC in an interview. It has always been emphasized that Feifan Automobile does not start from scratch, "but is carried out on the basis of SAIC’s huge resources".

On September 22nd, SAIC cooperated with PetroChina, Sinopec and Contemporary Amperex Technology Co., Limited, and Feifan Automobile also served as its own resource. Moreover, compared with Zhiji, Feifan and Jieneng Zhidian have a closer relationship.

"SAIC is in a difficult time now, and it is in urgent need of independent brands to do it as soon as possible. In the past, independent brands had a habit of having more brands, having more children and fighting, and the east was not bright and the west was bright. " Mr. Zhou said.

Although Wu Bing has been saying that Fei Fan and Zhi Ji do not constitute competition, in fact, the competition between them is inevitable.

The first is the competition for resources.

Feifan automobile is positioned at the high end, and Zhiji automobile is positioned at the high end. However, the price difference is not very big. The price difference between Feifan and Zhiji is about 50,000 yuan. As two independent new energy brands under SAIC, there is inevitably competition in the undertaking of SAIC brand resources.

In addition, the positioning of the two brands will overlap in the future.

The news learned by Lu Jiu’s business review is that Zhiji will launch a B-class car next year, which is the model that the company wants to take. This B-class car will have direct competition with Feifan.

"In fact, the L7 car is not a real car, it is a brand car. The real car is the B-class car released next year, and the company plans it like this. " "Just like Tesla, the earliest model started at 800,000, and then there were 300,000 models up and down," said Ren, a salesman at the Zhiji exhibition store.

Sales staff revealed that the B-class car released by Zhiji next year will be marked with ET5, Mmodel 3 and other models, which is Zhiji’s brand strategy.

Feifan R7 will be delivered at the end of October, and when the market runs away for some time, especially next year, Zhiji will launch a B-class car, when the two brands will directly fight.

If Feifan’s car sales are improving, SAIC will have to adjust its resource allocation in the case of tight resources.

To prove that he can be a "prince", Zhiji’s time is running out.

Hello, everyone, here is Huang Jieqiu, and it’s the same place at the same time. We meet again. Today is Friday, and there are few events. So if we read this article, let’s take a look at the three popular games tonight. It’s still the old saying, flowers bloom every day, and the following contents are all created for personal interest, for your own reference.

Bologna: Ranked ninth in Serie A last season, and performed well in Serie A this season, ranking eighth in the Serie A standings with 3 wins, 6 draws and 11 losses. Bologna is known as the king of draw in Serie A this season, with 4 wins, 6 draws and no defeat in nearly 10 games. The team’s morale is high. The team is also excellent in defense, especially in defense. In the last 10 games, the team only lost 6 pitches with an average of 0.6 goals, which is relatively average in offense. The team’s competitive ability at home is also excellent. Recently, except for AC Milan who scored 3 points away from home, all other Bologna are unbeaten.

Lazio: Serie A ranked second last season. This season’s performance was average. The team ranked seventh in Serie A with 5 wins, 1 draw and 4 losses. The team’s recent state has picked up, with 4 wins and 1 loss in the last five competitions showing quite good competitive ability. The team’s defensive and offensive performance this season is average. The team’s away ability is not too bright, with 3 wins and 4 losses in the last 7 games.

Comprehensive analysis: The two teams played against each other six times, and Bologna had two wins, one draw and three losses. From the historical record, Lazio had a certain psychological advantage, but it is worth mentioning that the two teams played against which team’s home six times, and this team was invincible. Based on the recent state and strength of both teams, I personally feel that Bologna is unbeaten at home in this game.

Leicester City: Last season, it was relegated from the Premier League. The key operation was to basically retain the lineup of last season’s Premier League campaign. The team won 13 wins and 1 loss in 14 rounds, and it was 14 points ahead of the third Leeds United in just 14 rounds. It can be said that Lecce City will return to the Premier League just around the corner. Two Premier League strikers in Leicester City, Valdi and Ishi Na Qiao, jointly scored 9 goals, and with Hall’s 5 goals and McCarter’s 4 goals, Lecce City’s frontcourt firepower was fully open. Leicester city’s recent form is impeccable, winning a series of nine consecutive victories in the league, only losing to Liverpool in the League Cup, but this does not affect their determination to return to the Premier League. This season, leicester city scored 6 wins and 1 loss at home, only conceded 3 goals in 6 games, and the defensive performance can be said to be impeccable.

Leeds United: Also as a demoted horse, it is not bad to be ranked third in the Championship. In the last five rounds, Leeds United achieved 4 wins and 1 loss. As a guest, the performance of Leeds United was slightly average, and all three losses occurred as guests. Although Leeds United is also one of the popular teams to upgrade, after 14 rounds of league matches, they have fallen behind the second Ipswich by as many as 9 points, and they have played one more round than their opponents. If you want to qualify for direct promotion at the end of the season, you should try to reduce the loss of points in future competitions. Leeds United scored 4 wins and 1 loss in the last 5 games, but lost to Stoke City in the last away game. Leeds United’s injuries are relatively serious. Spencer and Joe Roden are injured, and Stuart Dallas and Filpo can’t play this game.

Comprehensive analysis: The last two defeats were on the road. Compared with leicester city’s momentum, it is obvious that the White Legion still needs to work hard. In the face of another relegated horse Southampton, Leeds United lost by a big score on the road, while leicester city was able to take away three points on the road against Southampton. This also shows that leicester city is really capable of leading the British Championship at present, and this game is at his own home in Fox City, so it is still optimistic that Fox City can win three points!

Las palmas: He is a newly promoted horse this season. He has performed well on the whole. At present, he has achieved 4 wins, 2 draws and 5 losses, ranking 10th in the league. The team defeated almeria 2-1 in the last round, and achieved 3 wins and 1 loss in the last 4 games, which is in good condition. The team has scored 8 goals this season, and the offensive performance is not ideal. In the last 5 games, it has lost 6 goals, averaging 1.2 goals per game, and its defense is unstable. The team scored 2 wins, 2 draws and 1 loss at home, with a good performance and stable defensive efficiency.

Atletico Madrid: This season has performed well. At present, it has achieved 8 wins, 1 draw and 1 loss, ranking third in the league, and falling behind the top Real Madrid by 3 points in the case of one round less. The team defeated Alaves 2-1 in the last round, won all the last six league games, and also defeated the powerful Real Madrid, and recently performed very strongly in the game. The team scored 3 wins, 1 draw and 1 loss away from home, scored 12 goals and lost 3 goals. The offensive and defensive performance was excellent. Although Atletico recently fought on two fronts, its performance is still stable, and it has remained unbeaten in nine games. Las palmas has scored 1 win and 9 losses against Atletico Madrid in recent 10 times, and its past performance is obviously at a disadvantage. Las palmas’s recent performance is acceptable, and the team won two consecutive victories. However, Atletico Madrid’s recent state is relatively stable. Although it has fought on two fronts, it has achieved good results.
