Recently, Esther Yu, a post-90s actress, has attracted much attention due to a series of negative events. First of all, her two works "If You Are the One" and "Pray for the Present" have a poor reputation, and her acting skills and face value have been questioned and ridiculed by the audience. Subsequently, some paparazzi photographed her reversing illegally in the emergency lane of the expressway, which triggered a wide public discussion.

With the fermentation of the incident, not only the mainstream news reported it, but also the Beijing traffic police said through Weibo that two minibuses illegally backed out of the main road after missing the exit in the emergency lane. The police also pointed out that the two cars had other traffic violations and were currently under further investigation.

When Esther Yu first appeared at the airport after the high-speed reversing storm, she wore a white down jacket, sunglasses and a mask, dressed in a low-key manner, and clasped her hands all the time, which was in sharp contrast with her usual bright and lively image. Esther Yu’s fans expressed their love for her hand-clasping, believing that it was a sign of her grievance, sadness and helplessness. The last time she clasped her hands, she faced a full screen of abuse on her birthday. Only in this way can she ease her embarrassment. This time, just because she took the bus, she was accused because of the driver’s driving problems. Fans thought she was very pitiful.

However, the majority of netizens didn’t buy the behavior of Esther Yu and his fans. Some people left a message saying that a group of maids were actually distressed by Lao Lai’s daughter, and 208, who didn’t pay back the money at the age of 30, really made people feel distressed. Someone felt distressed when they clasped their hands, so it was better to feel distressed by themselves who had no money first.

For the high-speed reversing incident, Esther Yu Studio issued an apology shortly after the incident, and said that Esther Yu was riding a third-party vehicle, and hoped that everyone would not follow the car and follow. This seems to imply that the driver had to reverse illegally because of stalking fan’s tail. However, it is worth noting that before her debut, Esther Yu had an illegitimate behavior of idolize, including being an actor Kim Soo Hyun’s illegitimate powder, buying the same flight with Lee MinHo, and exposing Lee MinHo’s hotel room number on social platforms. Although these behaviors happened before her debut, as an adult, it is really not advisable for her to go her own way after repeated reminders from the staff.

Nowadays, the Internet has a memory, and Esther Yu’s illegitimate behavior has finally returned to him. Many people don’t understand why capitalists always send their children into the entertainment circle. Esther Yu’s face value and acting skills are average, but she is hard-blown to be cute. Her lines are also embarrassing. It is really puzzling that 40 billion Shanghai princesses should look up to the salary of 208W in the entertainment circle.

　　Editor’s Note: The 5th world internet conference opened in Wuzhen, Zhejiang on November 7th, and the Supreme Leader of president sent a congratulatory letter. The Supreme Leader pointed out that today’s world is experiencing a broader and deeper scientific and technological revolution and industrial transformation.

　　Facing the changes and challenges of the global Internet, what kind of answer will China give? The world is looking forward to it..

　　In different historical stages of the development of human society, the social production network has been expanding, from one country to many countries, and from many countries to the final globalization. In this process, the social production network has become increasingly complicated in space, between industries and even within products. At the same time, the key content of production network exchange has gradually changed from agricultural products, industrial products and capital flow to data flow and information flow. Economic powers also show different industrial characteristics at different stages: agricultural power, industrial power, trade power and financial power. Under the background of the internet age, information flow and data flow are becoming new means of production, and at the same time, they are becoming more and more important contents of national security, and economic powers will increasingly rely on network powers.

　　The world today is experiencing an information revolution, which will bring another qualitative leap in productivity and have a profound impact on the development of international politics, economy, culture, society, ecology and military affairs. China must seize this historical opportunity, and use information flow to drive the flow of technology, capital, talents and materials to promote high-quality economic development. China has its own unique advantages in building a network power.

　　China has the advantage of market scale in building a network power.

　　The network has the characteristics of increasing marginal revenue. Every time a new user is added to the network, its scale revenue will be greater. China has a population of nearly 1.4 billion, and the existing Internet users and mobile phone users are huge. From children to the elderly, almost everyone can use smart phones. China’s population advantage is a huge supporting force for building a network power, which is an innate condition that many developed countries in the world do not have. There are world-class Internet companies like Ali and Tencent in China, which is inseparable from the huge domestic market in China. Making full use of population advantages and giving full play to the role of population base can make China’s network power construction get twice the result with half the effort and form a huge scale effect on economic development.

　　Today’s network era is already different from the traditional free Internet era, and innovations in content and form have spawned various profit models. The network era will not bury anyone’s talent, and every participant can use the network to create wealth. They are both creators and users of Internet services. Therefore, building an all-round cyberspace and expanding the coverage of network infrastructure can make China’s market scale advantage play to the greatest extent in the construction of a network power.

　　Building a strong network requires higher talents and infrastructure.

　　The characteristics of a network power are as follows: a country has strong technical strength, strong ability to resist network risks and network governance, which can achieve a high level of network efficiency as well as a high level of network security. No matter what stage of social development, talents and infrastructure are two important pillars of building an economic power. The innovation ability of the former depends on the national talent training and incentive system, while the latter depends on the government’s investment, supervision and maintenance of infrastructure. The construction of a network power still needs to rely on the construction of Internet talents and network infrastructure.

　　For a micro-enterprise, the Internet is first and foremost a technology-intensive industry, which cannot be supported by first-class technical talents. After more than 20 years of unremitting efforts, China has gained gratifying achievements and rich technical experience and professionals in the field of Internet technology. Since 2003, the number of related patents applied by China has increased by 10% year by year. Stimulated by market demand, a large number of college graduates flock to Internet enterprises after graduation, providing a large number of IT talents for the Internet industry. The younger talent team is more conducive to technological progress and innovation. In 2017, among the top ten Internet companies in the world ranked by market value, China’s Alibaba, Tencent, Baidu and JD.COM occupied four of them. China’s Internet practice and innovation is based on its own national conditions, permeating all aspects of people’s daily life, and basic production and life have been closely linked with intelligent networks. However, although the total resources of Internet science and technology talents in China are large, high-end technical talents are still scarce resources.

　　For a country, especially for a big country like China, the construction of a network power has put forward higher requirements for infrastructure. The infrastructure referred to by a network power includes not only telecommunications and Internet infrastructure construction in a narrow sense, but also the interaction between the network economy and the real economy. Network infrastructure also includes network basic theory and core technology, as well as related facilities related to network security. For example, information infrastructure network security protection, network security information co-ordination mechanism, means and platform. "To get rich, build roads first", and network infrastructure is the "highway" in today’s information age.

　　The essence of a network power is an information technology power. Network development is supported by technology, and the core technology is the biggest difficulty that restricts China’s construction into a network power. With the core technology, we can have a comparative advantage in technology, from following developed countries to completing "overtaking in corners". The birth of the core technology is to try it out through massive trial and error. This not only requires that the scientific research assessment mechanism should be inclusive and allow researchers to fail; But also put forward higher requirements for the financing mechanism, that is, the financing mechanism should also be inclusive and tolerant of repeated failures in technical research. Therefore, our scientific research assessment mechanism should be reformed, from short-term and high-frequency assessment to longer-term assessment, from quantitative assessment to quality assessment and peer reputation assessment. In addition, for the financing mechanism, it also requires the development of equity financing, the development of multi-level capital markets, and the change of the financing structure mainly relying on bank loans.

　　China’s construction of a network power is facing the problem of integration with the real economy

　　Undoubtedly, the development of the Internet has played a positive role in promoting economic development, but at the same time, new technologies will have an impact on traditional industries. This "creative destruction" of the network economy has also caused a certain degree of impact on the real economy. For example, the retail service industry tends to weaken under the impact of the Internet. We need to understand this contradiction from two aspects: on the one hand, like other new technologies and new production methods in history, network technology has improved the efficiency of information flow and production, and it is the "cake" of the whole economic output. The distribution problems arising in this process require the state to maintain basic social equity through taxation, subsidies and redistribution; On the other hand, the real economy and the Internet can achieve a benign interaction and achieve a win-win situation for both sides.

At the same price and level, is "L" better this time or "PLUS" more worth starting with?

Many Chinese people pay attention to "doing great things with small money", which is very applicable in the domestic SUV market. Isn’t it beautiful to buy more satisfactory products at a lower price? In the 150,000-class SUV market, consumers have many products to choose from, but at the same time, they should give consideration to configuration, space and power. Chery Tiggo 8 PLUS and Geely Haoyue L, which have just been listed, are one of the few products worth starting with.

These two models are attractive to family consumers. Then, we might as well compare the strength of the two from the triangle of space, configuration and car cost to see who is more outstanding. We choose Geely Haoyue L 2.0T DCT flagship model (guide price: 147,900 yuan) and Chery Tiggo 8 PLUS Kunpeng Edition 390TGDI DCT Luxury Edition (guide price: 149,900 yuan) for comparison.

Haoyue L size is better than Tiggo 8 PLUS.

In appearance, both models give people a good sense of atmosphere and luxury, and each has its own advantages in design. However, Geely Haoyue L has just been listed, and it adopts the latest design language of Geely family, which will be stronger than Tiggo 8 PLUS in freshness.

Both models are positioned as medium-sized SUVs, and both adopt a seven-seat layout, and their bodies are not small. However, the overall size and wheelbase of Geely Haoyue L are more prominent than that of Tiggo 8 PLUS, which can be said to be larger than that of Tiggo 8 Plus. In contrast, the weight is improved. The curb weight of Geely Haoyue L is 1710kg, while that of Tiggo 8 PLUS is only 1587kg.

In terms of the actual ride experience, the experiencer with a height of 180cm can get a good head space in the first two rows of Geely Haoyue L. After adjusting the second row of seats to the legroom of about one punch, the third row of seats still has legroom for two fingers. It is worth mentioning that there is still about one punch in the head space of the third row.

Similarly, the experiencer with a height of 180cm also has a good space experience in the first two rows of the Tiggo 8 PLUS, but the leg space of the third row of seats is about one punch, and the head is about two fingers away from the roof.

For storage space, Geely Haoyue L and Tiggo 8 PLUS can get trunk volumes of 2,360 L and 1,930 L respectively when the second and third rows of seats are all laid down. It can be seen that if we pay attention to the storage capacity in the car, the longer and taller Geely Haoyue L is more worthy of choice. If we pay more attention to the space, the first two rows of the two cars perform better, and the third row has its own advantages and disadvantages, but there is no big problem in short-distance travel.

Haoyue L has richer comfort configuration, and Tiggo 8 PLUS has stronger power.

The performance of the 150,000-class domestic SUV in terms of configuration will not be too far behind. The basic active and passive safety configurations of the two models are satisfactory, including lane departure warning system, lane keeping auxiliary system, lane centering and active braking. However, the parallel assistance, DOW door opening warning, rear collision warning, front parking radar and reversing vehicle side warning system provided by Haoyue L are not provided by Tiggo 8 PLUS, while the latter provides fatigue driving tips, and the rear airbag and knee airbag functions are optional, but Haoyue L is not equipped.

In terms of other configurations, the front row ventilation, lumbar adjustment/position memory of the main driver’s seat, front and rear adjustment of the second row, wireless charging of mobile phones, Bluetooth keys and other configurations owned by Haoyue L are not equipped on the Tiggo 8 PLUS. Tiggo 8 PLUS provides boss key, rear central armrest with cup holder, induction trunk and other configurations.

The configuration levels of the two are very close, but in contrast, the advantages of Geely Haoyue L are mainly concentrated in the front row, while the Tiggo 8 PLUS is concentrated in the back row.

In terms of power, both models provide 2.0T engines, but there are some differences in data. Geely Haoyue L gave up the 1.8T of the same model of Haoyue L, and its 2.0T engine can produce 160 kW/325 N m book data in generate, while the 2.0T engine of Tiggo 8 PLUS is more powerful, and the book data of 187 kW/390 N m is even stronger than that of Geely Haoyue L. It is worth mentioning that the comprehensive fuel consumption of Tiggo 8 PLUS under WLTC is 7.49L/100km, which is 0.13L/100km less than that of Geely Haoyue L. The higher fuel consumption level of Geely Haoyue L is related to its larger body size and higher kerb quality.

The fuel cost of Haoyue L is higher.

Finally, Brother Gu analyzed the car cost of the two cars according to their fuel costs. The comprehensive fuel consumption of Geely Haoyue L under WLTC working condition is 7.62L/100km, and only 95 # gasoline is supported. At present, the oil price of 95 # gasoline in Guangzhou is 8.65 yuan/L.. According to the calculation of driving 20 thousand kilometers a year, we can calculate that the fuel cost of Geely Haoyue L is about 13,182.6 yuan a year.

The comprehensive fuel consumption of Tiggo 8 PLUS under WLTC condition is 7.49L/100km, and 92 # gasoline can be filled. At present, the oil price of 92 # gasoline in Guangzhou is 7.99 yuan/L.. Using the same calculation method, we can calculate that the annual fuel cost of Tiggo 8 PLUS is about 11,969.02 yuan, which is 1,213.58 yuan less than that of Geely Haoyue L.

Of course, the cost of car use also includes insurance costs and maintenance costs. The displacement and positioning of the two models are similar, so there will not be much difference in insurance costs. As for the maintenance cost, Tiggo 8 PLUS supports a three-year or 100,000-kilometer vehicle warranty, and Haoyue L supports a four-year or 100,000-kilometer vehicle warranty. Parts with non-human damage can be repaired free of charge during the warranty period, so the maintenance cost of the two will not be much different, except that Haoyue L’s warranty scheme is longer and there will be more protection in the later car use process.

It must be said that the comprehensive performance of Geely Haoyue L and Tiggo 8 PLUS is close to the level of 200,000-class SUV. However, in terms of space performance, Geely Haoyue L is indeed more prominent, while in terms of power performance and fuel economy, Tiggo 8 PLUS is better, and it is indeed more friendly in the era of high oil prices.

In recent years, the transformation wave of new energy automobile industry has continued to surge, and China brand has made progress with the dual transition of technology and industry, and bravely rushed to the forefront of the torrent of the times. As a masterpiece of Haval’s new energy in the true sense, Haval Xiaolong MAX (parameter picture) is the first to take a brand-new Hi4, which opens the era of all-people electric four-wheel drive with "the experience of four-wheel drive and the price of two-wheel drive".

Today (July 1st), only 45 days after the launch of the Haval Xiaolong series, it officially ushered in the milestone moment of the 10,000th vehicle off the assembly line. In June this year, the sales volume of the Haval Xiaolong series reached 6,098 vehicles, a significant increase of 97% from the previous month. The rapid rising momentum confirms the excellent product strength of Xiaolong series. At the same time, Haval also released the OTA plan of Xiaolong MAX, helping Haval Xiaolong series to set off a new wave intelligently.

New OTA to build smart cockpit ceiling

Haval Xiaolong MAX has refreshed the smart ceiling in the field of new energy SUV in China with the new generation of Coffee OS smart cockpit and coffee smart driving. Today, the OTA function upgrade plan is ushered in, which further enhances the user experience with technology upgrade and builds an unbreakable smart moat.

It is understood that when the new OTA is upgraded, Haval Xiaolong MAX will add 3D car control function, which can control the opening and closing of windows, skylights and tailgates, and realize the control of HUD display screen. The 3D car model will also show the switching of vehicle driving modes in the form of more scientific and technological sense and e-sports. At the same time, the energy management function is integrated into the car control car design page, and the change of vehicle energy flow is presented in 3D, so that users can truly perceive the power-saving logic of Haval Xiaolong MAX.

In addition, the Haval brand has also completely renewed the car application, deeply developed and adapted to the Himalayas, and the UI interface has been completely renewed, breaking through the voice barrier between the APP and the car. Users can select, play and switch through voice. On-line sound museum function, users can query musical instruments, animals, transportation, life, nature and other sound effects through voice assistants. Add startup animation switch, support custom drop-down panel, and add four shortcut switches: low-speed pedestrian warning sound, power mode, driving mode and smart parking.

In addition, Haval will continue to carry out the second OTA upgrade, and Haval Xiaolong MAX will be equipped with the AI ? ? big model. Through hundreds of millions of data accumulation, the AI ? ? big model will give the vehicle an active travel plan, combined with user preferences and algorithm analysis, to provide car owners with massive travel options.

Haval Xiaolong MAX will also be equipped with handcart interconnection and interaction, including super desktop, navigation relay and other functions. Among them, after the car is paired for the first time, it is detected that the paired mobile phone is on the car, and the mobile phone APPlication can be directly presented on the car screen, and the control of the mobile phone app can be realized through the car terminal. The experience brought by the navigation relay function is that the route follows people, the car screen guides the driving route, and the mobile phone relay is taken when you get off the bus, so as to navigate the remaining routes, realizing the seamless relay between the car navigation and mobile navigation, and ensuring continuous navigation.

Review of Haval Xiaolong MAX model

Compared with young people, the shape of Haval Xiaolong MAX can be said to be very eye-catching. The borderless mesh grille on the front face has a strong sense of the future.

The side of Haval Xiaolong MAX adopts a penetrating waistline to create a visual lengthening effect. The rear of the car looks relatively simple. The taillights do not use the through taillights, but adopt the double-layer light strip design, which has strong recognition. Xiaolong MAX also comes standard with 19-inch rims.

The interior style of Haval Xiaolong MAX is quite exquisite. The multifunctional three-position flat-bottomed steering wheel with a 12.3-inch triple screen is very attractive. In addition, Haval Xiaolong MAX has mobile phone holders on both sides, all of which support wireless charging. The car system is equipped with Snapdragon 8155 car chip to ensure the smoothness of the operating experience.

In the new energy era, intelligence is standard. Haval Xiaolong MAX is equipped with a new generation of Coffee OS intelligent cockpit system, which is the leading industry of Great Wall Motor. The voice assistant wakes up 300ms, responds 400ms, and the vehicle control skill responds 900ms, crushing competitors. Vehicle control covers 12 fields, including vehicle control and vehicle setting, system setting, navigation, multimedia and air conditioning.

In terms of power, the Hi4 intelligent electric hybrid four-wheel drive system carried by Xiaolong MAX consists of a 1.5L engine and front and rear dual motors. The comprehensive power of the system is 279 HP and the comprehensive torque is 585 Nm. The transmission system is matched with a 2-speed DHT gearbox. Commuting in the city, pure electric drive mode has become the first choice, which can achieve 105 kilometers of "zero fuel consumption" pure electric cruising range, and the fuel consumption of the whole vehicle under comprehensive working conditions is as low as 1.78L/100km.

Set a new benchmark for technology research and development

The new energy era is accelerating industry changes, and profound intellectual strength will help brands win the future. As a car company that loves technology, Great Wall Motor has always insisted on excessive investment in R&D. In 2022 alone, the R&D investment has exceeded 12 billion yuan, and technological innovation has helped the core competitiveness to continue to improve; By 2025, the cumulative R&D investment will reach 100 billion yuan.

In terms of channels, Haval New Energy Network opened 100 stores, creating a business ecology that is not limited to cars with the new model of "service+products", and helping Haval New Energy to open a new era. Up to now, Haval New Energy Network has completed the deployment of 326 Haval New Energy Network stores in major sales regions across the country; It is estimated that by the end of 2023, Haval’s new energy brand channel will cover 200+ prefecture-level cities nationwide and 800+ stores will be officially put into operation.

As the most successful SUV brand in China, with the good reputation accumulated by the brand and the strong product strength of Xiaolong series, I believe that Haval brand can occupy a place in the new energy market. Haval, which is full of vitality, strength and influence, will bring users a low-carbon and environmentally-friendly travel experience with the strength of leading hybrid technology, and inject a strong force into the revitalization of China’s automobile industry.

With the release of the "double carbon" policy to various industries, the introduction of the EU carbon tariff policy CBAM, the rural revitalization has become a national plan, the development of photovoltaic industry chain will be more stable, and the dynamic changes of policies such as electricity trading marketization can be predicted, and the installed capacity of photovoltaic will soon usher in a spurt growth. Grasping the opportunity of rapid industrial development, I believe that more distribution partners will join hands with Huawei Smart Photovoltaic, and in 2023, we will achieve greater success and emerge more excellent partners!

On June 1st, BYD’s 2022 Tang EV was officially listed, and the price was 279,800 yuan-339,800 yuan after comprehensive subsidies. At the same time, four car rights and interests of "2 worry-free car purchase policies, 1 worry-free car protection, 5 exclusive VIP services and 5 online services of Zhilian" were launched simultaneously, which can be described as full of sincerity.

As the leader of pure electric SUV, the flagship strength of 2022 Tang EV has evolved in all dimensions, and with the three leading factors of "battery life, safety and technology" and the brand-new luxury quality such as six seats, it has set a new benchmark for the value of high-end pure electric SUV. Previously, the 2022 Tang EV also achieved an amazing record of only pre-selling 8505 units in 24 hours, and its strength rewritten the market structure of 300,000 pure electric SUVs.

The longest battery life is 730km, widening the user’s travel radius.

In terms of endurance performance, the 2022 Tang EV far exceeds users’ expectations, and the two-wheel drive version of CLTC can last up to 730km under comprehensive working conditions, showing the king’s posture that continues to lead. At the same time, the new car also offers 600KM exclusive type and 635KM four-wheel drive flagship type.

The 2022 Tang EV is equipped with a 108.8kWh large-capacity blade battery, which has the deepest power reserve of all BYD models, ensuring the industry benchmark endurance performance. In addition, thanks to the world’s first battery pack direct cooling and direct heating technology and wide temperature range high-efficiency heat pump air conditioning, the thermal efficiency is increased by 20%, and the energy consumption of air conditioning at low temperature is reduced by about 40%, which continues to help long battery life. Coupled with the new EV Dragon Face low wind resistance front face, AGS active air intake grille and 21-inch low wind resistance wheels and other wind resistance reduction technologies of the whole vehicle, it finally makes its battery life up to 730km, making it difficult for its rivals at the same level.

For a long time in the past, when it comes to pickup trucks, many people’s first impression is the image of a "tool truck" driving on a mountain village road. Until the last two years, domestic pickup truck fans began to grow, and they and all kinds of pickup trucks can be seen in more and more cross-circle activities. Faced with this grand occasion, we have to thank the Great Wall Gun for its persistence and efforts, and since its listing in 2019, it has held high the slogan of "making pickup trucks popular"

200,000 sales base, the Great Wall artillery sword refers to the whole world.

Up to now, the Great Wall Gun has achieved a sales volume of 200,000 in just two years. It is worth mentioning that this achievement also includes important contributions from overseas markets. It has achieved good results in more than 50 countries and regions around the world, such as Australia, New Zealand, Chile, South Africa, Saudi Arabia, Kuwait, Bahrain and Egypt, and its market performance has continued to strengthen.

Taking the Chilean market as an example, Great Wall Gun has successfully captured a large number of local pickup fans with its product strength far exceeding that of competing products at the same level. From January to July this year, thanks to the outstanding contribution of Great Wall Gun, the sales of Great Wall pickup trucks in Chile totaled 4,773 vehicles, ranking second in the overall market and the first in China brand. In July, it successfully won the title of the first pickup truck market in Chile.

Take root in the local culture and promote the pickup truck of the Great Wall to continue to rise.

The reason why the Great Wall Cannon can be used in overseas markets like a duck to water has a lot to do with its localization development strategy. It has always been rooted in local culture. Whether it is in Australia, it is a strong alliance with IRONMAN, the most popular triathlon in the local new middle class, sponsoring the women’s netball event Pulse in New Zealand, or combining "desert culture" to unlock new gameplay when it is listed in Saudi Arabia, we can see the intention of the Great Wall Cannon in digging deep into the local pickup culture. No wonder it can win wherever it goes.

Of course, the Great Wall Gun can now rank among the first camp in the global pickup truck market, not only because of its own strength, but also because of the full support of Great Wall Motor. Especially on the technical level, based on the R&D layout of Great Wall Motor in "seven countries and ten places" and the global production layout of "12+5", Great Wall Gun has become one of the few models in the pickup truck field that integrates multi-link rear suspension, 8AT and many leading intelligent driving assistance technologies.

　　(a) the accident.

　　At about 11: 50 on April 16th, 2021, five people, including Xie Xialing of Sichuan Hualun Electric Power Engineering Co., Ltd., went to the South Building to check the renovation progress of the control room, and found that the battery cabinet on the south side of the west battery room of the South Building caught fire and smoked, and immediately used the on-site fire extinguisher to dispose of it. Xie Xialing telephoned Liu Bo, the person in charge of Fuweisi Oil and Gas Company.

　　At about 12: 13, Liu Bo led Chen Yuanzhong and others to the scene and took fire extinguishers from the South Building and the North Building to participate in the fire fighting. Because the open flame was extinguished and continued to rekindle, Liu Bo assigned Chen Yuanzhong to the energy storage room of the North Building to cut off the AC side. Connect with the energy storage system and disable the photovoltaic system. At 12: 17, Liu Bo called the police. At about 12: 20, Liu Bo entered the North Building and told Luo Guangjun, the electrician on duty in Jimei Home Furnishing Company, to turn off the switch between the 6 kV distribution cabinet and the energy storage equipment.

　　At about 13: 40, Liu Zhange, an electrician of Jimei Home Furnishing Company, arrived at the duty room of the North Building and went to the 6 kV distribution room with Luo Guangjun to confirm that the switch between the distribution cabinet and the energy storage equipment had been disconnected. During the period, a large amount of smoke emerged from the south building, accompanied by deflagration from time to time.

　　At about 13: 45, Liu Zhange went to the hospital to check and found that Liu Bo and firefighters were injecting water into the outdoor underground cable trench, and then went to the 6 kV distribution room in the north building to check and found that the cable trench was full of white smoke, no accumulated water and a pungent smell. At about 14: 13, an explosion occurred in the North Building.

At 23: 40, the open flame was completely extinguished and the site was continuously cooled for 40 hours. At 16: 21 on April 18th, the site was cleared.

　　(3) Direct property losses caused by fire

　　The price was confirmed by Beijing Fengtai District Price Certification Center, and the statistics of Fengtai District Fire Rescue Agency confirmed that the direct property loss of this fire was 16,608,100 yuan.

　　Third, the cause and nature of the accident

　　(A) the direct cause

　　The public security organs combined with the analysis of on-the-spot investigation, investigation and interrogation,Exclude the suspicion of intentional criminal offence.

　　1. On-site inspection

　　After on-site inspection by fire rescue agencies, the battery cabinet in the west battery room of the South Building was over-fired, and the roof directly above the battery cabinet in the fifth group from west to east on the south side was burned and cracked, and the concrete part of the top floor was missing. The battery cabinet area had the characteristics of initial fire. Combined with the testimony of relevant witnesses, it is determined that the fire site of the South Building is located at the battery cluster at the north end of the fifth battery cabinet, from the south side of the west battery room to the east, at the battery modules on the 8 th to 10 th floors from bottom to top.

　　The walls on the east and west sides of the energy storage room in the north building were blown up and flew out, all the window glasses on the south side were destroyed, and the upper floor partially collapsed; The indoor energy storage converter, control cabinet and battery cabinet are dumped to the south as a whole; The deformation of the lower end of the battery cabinet in the second group from west to east is the most serious, and the steel beam between the battery cabinet base and the cable trench (the connection is not blocked) is more bent upward than the other three groups of battery cabinets. In the battery management system of 7 clusters of battery cabinets in this area, the components in the battery management system of the third cluster from west to east are scattered and displaced, the positive and negative relays have fallen off and the cover plate is missing, which is more serious than the other 6 clusters. It is determined that this is the initial ignition source position.

　　There is a small amount of water at the bottom of the outdoor underground cable trench between the north and south buildings, and there are traces of smoke in the trench, and oily residues are deposited at the bottom; Some cables in the cable trench have traces of fire on their surfaces; The cable trench between the northern end of the cable trench and the cable trench in the north building is not tightly sealed, and there is a gap. There is no seal between the cable interlayer in the southern end and the south building.

　　2. Detection and identification

　　Appraised by Tianjin Fire Material Evidence Appraisal Center of Fire and Rescue Bureau of Emergency Management Department, the negative terminal of battery module on the 9th floor at the fire site of South Building has an internal short circuit fault in the innermost battery cell in the fifth row. The battery is a square battery, and the electrode material conforms to the characteristics of lithium iron phosphate battery.

　　Tested by Beijing Physical and Chemical Analysis and Testing Center, the main components of the battery electrolyte of the same model in Nanlou provided by the battery supplier are a mixture of methyl ethyl carbonate, ethylene carbonate and phosphorus-containing inorganic salts; Methyl ethyl carbonate was detected in soil (muddy) and volatile organic compounds such as methyl ethyl carbonate and benzene series were detected in gas in outdoor underground cable trench.

　　3. Experimental analysis and simulation.

　　The battery safety laboratory of Tsinghua University Institute of Vehicles and Transportation conducted an experimental analysis on the square battery which was the first to break down in the South Building. The out-of-control battery will produce ejecta, mainly methyl ethyl carbonate vapor, hydrogen, methane, carbon monoxide, carbon dioxide and so on.

　　The smoke simulation conducted by the Institute of Building Fire Prevention of China Academy of Building Research shows that after the south building caught fire, the smoke mixture (including the thermal runaway injection product of the lithium iron phosphate battery which was not fully burned) generated at the scene can enter the indoor cable trench of the north building through the outdoor underground cable trench. Before the explosion of the North Building, the concentration of flammable and explosive gas was about 31%, and the total amount was not less than 280 cubic meters.

　　The explosion process was simulated by the State Key Laboratory of Explosion Science and Technology of Beijing Institute of Technology: when the flammable and explosive components (hydrogen, methane, carbon monoxide, methyl ethyl carbonate, etc.) in the North Building reached 200 cubic meters and were detonated by the ignition source in the energy storage room of the North Building, the explosion damage scene obtained by simulation was consistent with the accident scene, and the explosion equivalent was 26 kg TNT.

　　4. Experts demonstrate and analyze the situation

　　Based on the analysis of investigation, on-site inspection and physical evidence identification, it is found that the battery thermal runaway fire in the South Building is caused by the internal short circuit fault of lithium iron phosphate battery in the west battery room.

　　Combined with the analysis of on-site video, on-site inspection and material evidence identification, the explosion of the North Building conforms to the characteristics of volume explosion, and it is determined that the explosion is gas explosion. The explosive substance in the North Building is the explosive gas formed by the mixture of flammable and explosive components in the thermal runaway injection product of the lithium iron phosphate battery in the South Building and air. The initiation point is located in the energy storage room of the North Building, excluding the factors of fire source caused by personnel activities and uncontrolled ignition of the battery, and it is determined that the ignition source is the electrical spark generated in the energy storage room.

　　After analysis, the smoke containing the thermal runaway injection product of lithium iron phosphate battery diffused from the outdoor underground cable trench into the north building, and entered the battery system with high voltage (nominal 720 volts) DC charged state, which led to the action of the relay (located at the bottom of the battery cabinet) to generate electrical sparks.

　　5. The direct cause of the accident

　　According to the on-site inspection, testing and identification, experimental analysis, simulation and expert argumentation of fire rescue institutions, the investigation team comprehensively analyzed the direct causes of the accident as follows:

　　The direct cause of the fire in the south building is the internal short circuit fault of the lithium iron phosphate battery in the west battery room, which caused the battery to get out of control and catch fire.

　　The direct cause of the explosion in the North Building was the internal short circuit fault of the single lithium iron phosphate battery in the battery room of the South Building, which caused the battery and battery module to spread out of control and catch fire. The flammable and explosive components generated by the accident entered the energy storage room of the North Building through the cable trench and spread, and mixed with air to form explosive gas, which exploded when it met with electric sparks.

　　(2) Indirect causes

　　1. The responsibility of the safety subject of the enterprise involved is not implemented, and there is a problem of construction before filing in the construction process; Continue to operate in the event that the battery pack leaks, heats up and smokes many times in the incident area, but the safety hazards are not completely eliminated; The two ends of the outdoor underground cable trench between the north and south buildings were not effectively separated and blocked, and the accident emergency response plan was not formulated according to the actual risk of the site.

　　2. It is not enough for the relevant units to study and deploy and supervise the implementation of safety supervision and inspection; The research on the high-quality development of new energy projects under the premise of ensuring safety is not deep; The investigation of safety hazards is not comprehensive and thorough, and the safety risks existing in the construction, operation and maintenance of the incident project are neglected and out of control.

　　(3) Nature of the accident

　　In view of the above analysis, according to the relevant national laws and regulations, the investigation team determined that the "4 16" large fire in Fengtai District was a liability accident.

　　Iv. Suggestions on handling the responsible personnel and units of the accident.

　　In order to draw a profound lesson from the accident, earnestly practice the concept of life first and safe development, and effectively prevent and resolutely curb similar accidents, the following suggestions and measures are put forward:

　　(1) Strictly implement safety responsibilities. Jimei Home Furnishing Company should build and use leased premises and buildings according to laws and regulations, strengthen safety management, strengthen safety inspection and hidden dangers investigation and rectification. Forvis Oil and Gas Company should implement the fire safety responsibility system, improve the emergency response plan, strengthen safety education and safety inspection, and eliminate hidden dangers in time. Jingfeng Guowei Company should improve the company’s safety management system, strengthen distributed energy management, and carry out safety evaluation and inspection for installed roof photovoltaic.

　　(two) improve the construction and operation management of electric energy storage facilities and places. The Municipal Emergency Bureau takes the lead, and gives guidance jointly with the departments of development and reform, urban management, planning of natural resources, housing and urban-rural construction, economy and informatization, market supervision, fire fighting and rescue, etc. The relevant district governments rely on professional institutions to conduct safety risk assessment of suspended energy storage power stations in this area, evaluate the risk level of suspended energy storage power stations, and put forward work opinions. The Municipal Development and Reform Commission takes the lead, and the Municipal Emergency Bureau cooperates with it to organize experts and professional institutions to re-examine the construction plan for all projects under construction and projects that have not been put into construction of energy storage power stations. Only after passing the assessment can the construction be carried out. The Municipal Urban Management Committee shall, together with relevant departments, formulate technical standards to standardize the design, construction, acceptance and operation management of electric energy storage facilities in this Municipality. The Municipal Market Supervision Bureau and the Municipal Bureau of Economy and Information Technology shall establish and improve the quality management system of batteries and their energy management systems in energy storage power stations.

　　(3) Strengthen safety supervision and management. Fengtai District Government carried out a comprehensive survey of energy storage facilities in the whole region, established and dynamically updated basic accounts, and organized relevant departments to carry out comprehensive safety inspection and safety risk assessment. The Municipal Fire and Rescue Corps strengthened the fire supervision and inspection of electric energy storage places, formulated and improved the accident handling norms of energy storage power stations, strengthened the handling drills, and further improved the emergency rescue and handling work level of energy storage power stations.

　　(4) Continue to promote safe development. Urban management, development and reform, fire rescue, emergency management and other departments and Fengtai District Government should firmly establish the concept of safe development, put the prevention and resolution of safety risks in an important position, standardize the location and layout of new energy storage, establish and improve the working mechanism of overall coordination and management of photovoltaic power generation applications, and strengthen the quality management and safety supervision of related projects; For the electric energy storage facilities that have been built and are under construction, strengthen comprehensive analysis and judgment, find problems in time, solve problems, and prevent accidents caused by out-of-control pipe leakage. Fengtai District Government should plan the planning and construction of Dahongmen area as a whole, promote the regional wholesale market in an orderly manner, and promote functional remodeling, industrial upgrading and quality improvement.
