On August 20th, the domestic 3A masterpiece Wukong was put on sale, and its sales in three days exceeded 10 million, which made many domestic game manufacturers envious. Among the new energy logistics vehicles, there are also many models with such momentum. Today, let’s take a look at these new energy logistics vehicles that exploded in a short time and the reasons for their explosion.

Remote xingxiang v

On March 7, 2022, the series was officially listed. According to the data of tram resources, in March and April, 2022, Remote Star Enjoy V did not squeeze into the TOP list, but ranked fifth in the list of new energy logistics vehicles in May, 2022, and dominated the sales list of new energy logistics vehicles for 16 consecutive months from October, 2022.

In terms of sales volume, the main sales volume of Remote Star V Series comes from its six-party model Remote Star V6E. The container size is 2800*1600*1320mm, and the container volume is 6.0m3 It is equipped with various battery configurations, which are supported by battery factories such as Contemporary Amperex Technology Co., Limited, Guoxuan Hi-Tech and Anchi New Energy. The battery capacity is 38-46kWh and the working life is 240-295km.

Before the launch of the V family products, the remote new energy commercial vehicles also had other early new energy VAN series models, such as the remote star E6 of the Sea Lion light bus and the remote star E5L of the micro-plane model, but there was no competitive product in the market segment between them.

The remote Star-Enjoy V-series vehicle is not only the first product aimed at this market segment, but also the first VAN-series vehicle being developed by the remote new energy commercial vehicle. This car has perfected the layout of remote in the VAN market. At that time, the demand for platform freight electrification accelerated and the demand for generous models increased. The 6-sided mid-size model has the advantage of reducing the dimension of traditional micro-size models, coupled with the quality control of remote new energy commercial vehicles, the accumulated market reputation and dealer network, from the product itself to the market demand, all determine its explosion attributes.

With the demand of freight market, at present, the long-range Star-Enjoy V series has further developed seven large-scale long-range Star-Enjoy V7E and individual users’ long-range Star-Enjoy V6E bright window models. It can be seen that with the gradual increase in sales of new energy logistics vehicles, the demand for generosity and multi-occupants is also changing gradually.

Kairui finless porpoise

Kairui series is a mid-size model launched by Kairui New Energy in June, 2022. According to the data of tram resources, since the launch of Kairui finless porpoise, it has not made it into the top ten for only three months, and it ranks in the top ten every other 22 months, which is also a real explosion.

From the point of view of parameter configuration, Kairui container has a size of 2785*1595*1310mm and a volume of 6m. It is equipped with various battery configurations, which are provided by Guoxuan Hi-Tech, Contemporary Amperex Technology Co., Limited and Zhongchuang Singapore Airlines respectively. The battery capacity covers 32-42kWh and the cruising range is 221-285km, among which the most popular configuration is Guoxuan Hi-Tech 40.55kWh version.

The Kairui finless porpoise series is backed by the sales network built by Kairui before, and the space and power of the container are sufficiently increased to meet the demand of platform freight. It is a rare six-sided mid-size model at that time. In addition, the most important thing is that this car has been optimized in the width of the cargo compartment, the wheel-bag spacing, the width of the side-slip door, etc., and it has achieved the "three widest in the same class", which provides real convenience for freight drivers, which is why it stands out among many models.

In 2024, Kairui New Energy also launched two expansion products, Kairui finless porpoise E7 and Kairui, and also launched a version of split tailgate, which improved the layout of market segments, and at the same time, the bright window model was also launched.

Ruichi EC75

Ruichi EC75 is a 7-square model launched by Ruichi New Energy at the end of 2023. It was pushed into the sales list of new energy logistics vehicles in the second month after it went on sale, and it continued to dominate the sales list of new energy, which was an out-and-out explosion at the beginning of this year.

In terms of parameter configuration, the dimensions of the Ricci EC75 container are 2830*1740*1400/1450mm, and the container volume is 6.9/7.1m3 It is equipped with batteries provided by Contemporary Amperex Technology Co., Limited and Zhongchuang Singapore Airlines, with a battery capacity of 41-50kWh and a cruising range of 252-310km.

The popularity of Ruichi EC75 can be said to be helped by time, location, people and all three.Since the second half of last year, as the freight rate continued to fall, the carrying capacity of the original small models was not enough to guarantee the income. It was a good time to upgrade the large-scale models and pull more goods to maintain the same income before, so the big face began to rise. Ruichi New Energy has laid a deep user base in the field of VAN vehicles by virtue of the reputation of EC35 series, and EC75 has a rising market soil, which is a geographical advantage; Finally, the product strength of Ruichi EC75 itself, solid 7-square space, double side sliding doors, excellent quality control, and many humanized details design in the cab, is human harmony.

At present, Ruichi EC75 is still making fine-tuning according to the market demand, and we also expect Ruichi New Energy to produce more good products.

Wuling yangguang

It is a 6.5-square mid-size model launched by SAIC-GM-Wuling in 2024, and its listing price starts at 71,800 yuan. From the sales data, Wuling Yangguang has increased rapidly since its official listing, and reached the top of the monthly sales list of new energy logistics vehicles in April 2024.

In terms of parameter configuration, the size of Wuling Yangguang container is 2830*1680*1365mm, the container volume is 6.5 m, and it is equipped with Wuling Red No.1 battery (Honeycomb Energy provides batteries and Huating New Energy provides assemblies), with a battery capacity of 41.9kWh, and the official cruising range is 300km. Some time ago, the tram resources also carried out a full-load measurement of Wuling Yangguang, and the endurance results will be announced soon.

The success of Wuling Yangguang, first of all, can not be separated from the dealer network and user base laid by SAIC-GM-Wuling in the era, not limited to the platform freight in first-and second-tier cities, but also focused on the huge number of individual user groups in second-and third-tier cities, the Wuling brand with its own aura, and the dealer network all over the country, which enabled Wuling Yangguang to quickly open the market. According to the data of tram resources, from 2024 to July, Wuling Yangguang sold a total of 20,830 vehicles, which were sold to 317 cities in 30 provinces across the country, with the highest sales volume in Dongguan, Foshan and Wuhan, but the sales volume did not appear to be excessively concentrated.

In addition to the brand influence and distribution system advantages of SAIC-GM-Wuling, the sales strategy of Wuling Yangguang has also given this car a lot of help. The operation of bright price sales+small power to lower the starting price is a wave of concern.

In addition, SAIC-GM-Wuling’s strategy in the passenger and cargo use of Wuling Yangguang is very radical. With the economic advantages of richer scene selection, lower premium and lower cost, the Ming-window van is very popular in the local market. At present, the demand and sales of open-window vehicles in Henan, Pearl River Delta in Guangdong and Nanjing in Yangtze River Delta have soared. By virtue of the economic advantages such as good insurance and unobstructed road, the Ming-window version not only meets the demand for goods, but also improves the income.

According to the sales data of new energy logistics vehicles released by tram resources in July, nearly two-thirds of Wuling Yangguang’s sales came from its bright window model.

summarize

From the operation of the head OEM, from the 5th to 6th parties, and now to the 7th party models, there has always been a demand for generous models for platform freight, which is one of the reasons for the hot sales of these models.

At the same time, the hot sale of open-window models has also sent a clear signal to many OEMs. In cities with third and fourth lines and below, the single loading capacity is often not high, and there are many dual needs of bringing people and goods, which has laid the foundation for the practicality of open-window models. The trend of open-window models in first-and second-tier cities is also good. Apart from the oil-for-electricity exchange of individual users and the road rights restrictions in specific cities, there is also a big influencing factor in insurance. Since 2023, the insurance cost has gradually increased, and there is still no downward trend today. Some users have even told tram resources that they cannot buy operating insurance, and open-window models can solve certain insurance problems.

However, returning to the above four models, it can be seen that all four models have the foundation stone of the previous products, and their own quality is not bad, so that they can become hot-selling products. What do you think of the above four models? Welcome to leave a message in the comment area to discuss.

Wuling Xingchen is equipped with a 1.5 T engine code-named LJO, which is a domestic engine independently developed by SAIC-GM-Wuling.

LJO is a 1.5T inline four-cylinder turbocharged engine. This engine may be biased towards home in power output, and its lower torque performance will be improved compared with the old engine. It is clear that the technical content of LJO engine is much higher than that of L2B engine, but what is the performance of this LJO engine carried by Wuling Xingchen? Let’s take a look together.

Also equipped with this engine are some models of Wuling Capgemini, the new Baojun 530, Baojun RS-5 and other series. Below is a comparison chart of some models.

In terms of power performance, the peak horsepower of Wuling LJO engine is 147 horsepower, the maximum horsepower speed is 5200 rpm, the maximum torque is 250N·m, and the maximum torque speed range is 2200rpm to 3400rpm. Compared with the engines of the same level in the whole industry, there is no obvious advantage.

The power system of Wuling Xingchen is equipped with two powertrains, 1.5T+6MT and 1.5T+CVT. With the support of CVT stepless speed change, the torque platform of the compression engine can further improve the low-speed dynamic performance of the vehicle, and basically eliminate the frustration when shifting gears. The transmission effect is still very good, which can make the vehicle have good dynamic performance.

The comprehensive fuel consumption of NEDC, a powertrain composed of LJO engine and 6-speed manual transmission, is 7.1 liters per 100 kilometers; The comprehensive fuel consumption of NEDC, a powertrain composed of CVT stepless gearbox with simulated 8 gears, is 7.7 liters per 100 kilometers. To tell the truth, fuel economy is not so good in engines with the same technical route. Multipoint injection is used in the fuel injection system, which is difficult to achieve high torque and high power by low pressure fuel injection technology in the intake manifold. Secondly, the efficiency of the supercharger is relatively poor. Under the premise that the torque is not large enough, only through the supercharger can the maximum torque appear earlier and fall later to achieve fuel saving and power improvement.

In terms of environmental indicators, the exhaust quality of LJO engine can meet the national sixth stage B emission standard, and the noise level combined with the pricing and positioning of vehicles is also acceptable.

Based on the overall performance of Wuling or Baojun models equipped with this engine, the power performance, economic performance, environmental performance, reliability and durability of Wuling LJO engine are above average, and the fuel economy is not bad. However, the performance of engine and transmission after loading is more important, and the performance of the same powertrain is different on different models.

Changan Auchan X5, a compact SUV with Wuling Xingchen, is equipped with JL473ZQ2 Blue Whale engine, which is equipped with a double scroll turbocharger to further compress the power. Coupled with the aluminum alloy cylinder head block, the weight of the car body is optimized and the fuel consumption is reduced by about 7%. The engine adopts in-cylinder direct injection technology, which can realize up to 5 fuel injections in one stroke.

Changan Auchan X5 2022 Sports 1.5T DCT Cyclone Charge This car has a maximum power of 132kW, a maximum torque of 300N·m, and a maximum torque speed range of 1250rpm to 3500rpm, which means that when using the car, you can output the maximum torque by slightly stepping on the accelerator, and the power output is strong and smooth.

From the detailed data comparison and analysis, the performance of LJO engine matched with Wuling Xingchen is better than that of JL473ZQ2 Blue Whale engine in Chang ‘an, although there are some gaps. LJO engines are basically in the middle and upper reaches of the industry. What do you think? Welcome to discuss in the comments section.

　　On April 25th, the first composite EPB shield machine independently developed by the National "863" Plan was successfully rolled off the production line in the shield industrialization base of China Railway Tunnel Group in Xinxiang City, Henan Province, which marked a substantial breakthrough in the research and development of shield machines and the localization of their manufacturing in China, filled a gap in this field in China and set up a brand-new milestone in this field.

　　The CTE6390 composite shield machine has a diameter of 6.3 meters and a maximum driving speed of 8cm/min. It not only has strong geological applicability, but also has made remarkable progress in adapting to curve construction, steering rectification, rolling rectification and improving geological conditions. The design also fully considers the emergency treatment of shield construction when the cutter head is trapped, the safety protection when entering the cabin under pressure, and the response to emergencies such as water inrush, which has higher safety and reliability.

　　This shield adopts the operation mode of "independent design, independent research and development, and global procurement" and adheres to the design concept of "reliability, applicability, economy and advanced", realizing the leap from the key technology of shield to the whole machine manufacturing, realizing the digestion, absorption and re-innovation of foreign advanced technology, achieving the expected purpose in the aspects of localization rate of shield and cost reduction, and also making China’s shield manufacturing level enter the international advanced ranks. This success has opened up a more realistic and reliable channel for domestic tunnel and underground engineering to improve the construction speed, improve the safety and quality level, effectively control the cost and shorten the construction period, which will greatly promote the further popularization and application of shield machines in the domestic tunnel and underground engineering field, and will eventually end the history that China’s tunnel construction relies on foreign shields in complex geological environment.

　　China Railway Tunnel Group, a subsidiary of China Railway, undertook and successfully completed the development task of the shield machine. In recent years, relying on the engineering construction, the Group has found a correct position, actively undertaken the national "863" plan and the scientific and technological development planning project of the Ministry of Railways, attached great importance to the improvement of independent innovation ability, spared no effort in the research and development of shield machines, and made new achievements in TBM, shield machine assembly and debugging, cutter head manufacturing, hydraulic pressure, electronic control system and other aspects, thus giving birth to relatively sufficient research and development and manufacturing capabilities of shield machines and TBM. It took more than one year for CTE6390 composite shield machine to be successfully manufactured. It made full use of the construction platform of China Railway Tunnel Group, closely combined R&D with construction production, realized the strong combination of production, learning and research, and initially explored a shield machine manufacturing mode suitable for China’s national conditions, that is, taking the road of integration of design, manufacturing and construction.

　　Tunnel Group is the largest enterprise group in the field of tunnel and underground engineering in China, which integrates four functions: survey and design, building construction, scientific research and development and mechanical repair. At present, there are 50 professionals engaged in shield research and development, more than 400 people engaged in shield manufacturing, and more than 1,000 people engaged in shield construction. Shield machines have been used to successfully tunnel more than 100 kilometers, creating a precedent of crossing the Yangtze River three times and the Pearl River four times, and won three national scientific and technological progress awards in this field. At present, shield method is widely used in railway tunnels such as Shiziyang Tunnel in Guangzhou-Shenzhen-Hong Kong, Beijing Underground Diameter Line and subway sections in Xi ‘an, Guangzhou, Shenzhen and Shanghai. Rich experience in shield construction and numerous projects under construction provide the source of running water for shield research and development.

In 2015, China proposed to implement the national big data strategy. In 2017, during the second collective study in the Political Bureau of the Communist Party of China (CPC) Central Committee, General Secretary of the Supreme Leader emphasized that it is necessary to aim at the forefront of world science and technology, concentrate superior resources to break through the core technology of big data, accelerate the construction of independent and controllable big data industrial chain, value chain and ecosystem, promote the deep integration of Industry-University-Research with data as a link, form a data-driven innovation system and development model, cultivate a number of leading big data enterprises, and build a multi-level and multi-type big data talent team.

The new stage of informatization development opens a new chapter in digital economy and digital society.

Data is a faithful recorder of the development of human society, and its acquisition, processing and application have always played an important role in the development of human society. The rapid development of the Internet has brought the ubiquitous application of information technology. With this process, massive data is constantly produced, which contains great social, economic and scientific research value, and has become the third largest strategic resource after material and energy, and needs to be re-examined and developed urgently. The development of information technology provides automatic methods and means for data processing, and the concept of "big data" came into being.

Big data is not a novel word that was born in recent years. From abstract concepts to scientific research to applications in various fields, big data technology is entering a new stage of rapid development.

In 1998, American scientist John Marcy pointed out in an international conference report that with the rapid growth of data, there are bound to be four problems: data is difficult to understand, data is difficult to obtain, data is difficult to process and data is difficult to organize, and "big data" is used to describe this challenge. In 2007, Jim Gray, a pioneer in the field of database, pointed out that big data will become an effective way for human beings to touch, understand and approach complex real systems. With the help of big data, the method of "data+computer+algorithm model" provides the fourth means for human beings to explore the objective world after experimental observation, theoretical derivation and computational simulation.

If these two nodes of the concept of big data are still limited to the frontier areas of scientific and technological innovation, then the concept of big data "flies into the homes of ordinary people" marked by the best-selling of a book in 2012. This year, Victor Mayer-schoenberg, a professor at Oxford University, pointed out in his book "The Age of Big Data: Great Changes in Life, Work and Thinking" that data analysis will evolve from the traditional mode of random sampling, accurate solution and emphasis on cause and effect to a new mode of "all data", "approximate solution" and "only looking at correlation without asking cause and effect" in the era of big data.

What exactly is big data? At present, the consensus is that big data generally refers to a huge collection of data that cannot be perceived, acquired, managed, processed and served by traditional information technology and software and hardware tools in a tolerable time. It has many characteristics such as large data scale, rich sources, complex types and rapid changes. The essence of big data technology is to provide a new thinking and new means for human beings to understand complex systems. The arrival of the era of big data marks that informatization has crossed the digital stage characterized by stand-alone application and the networking stage characterized by Internet application, and officially entered the intelligent stage characterized by deep data mining and integrated application.

The new stage of informatization initiated by big data represents the brand-new application of a new generation of information technology, which breeds a more advanced economic form-digital economy with data as the main production factor, following agricultural economy and industrial economy, and accelerates the global step into the digital society. In the digital economy and digital society, data is a new type of means of production, cloud computing, Internet of Things and 5G are new production tools, artificial intelligence is a new type of productivity, and blockchain is a new type of production relationship that solves the problem that data is difficult to share openly in the Internet production relationship. The final application form of big data and new generation information technology is software, so software definition is also regarded as a new production mode in digital economy and digital society.

To improve the modernization level of national governance, big data applications are within reach.

Big data has been highly valued by many countries and industries. If big data can be effectively organized and used, it will greatly promote social economy, scientific research and national governance, and it will give birth to unprecedented opportunities. China has made great progress and achieved great results in using big data to improve the modernization level of state governance and to ensure and improve people’s livelihood.

Although it sounds abstract, big data is not far from our daily life. For example, in Beijing, Zhejiang and other parts of the country, big data is applied to simplify people’s work processes, optimize work experience and improve work efficiency. From "running back and forth" to "running at most once" and "not running at all" now, "data runs more and people run less errands". Beijing, Shanghai, Zhejiang, Guangdong, Guizhou and other places have set up provincial big data bureaus to comprehensively promote the transformation and upgrading of e-government and smart city construction to big data, and profoundly change the cognitive mode, thinking mode, working mode and collaboration mode of urban management. Big data is a "good helper" for the intelligent operation of cities. Various places have built "urban brains" to provide technical support for global situation awareness, quantitative analysis and judgment, and scientific and intelligent decision-making through data, so that decision-making can be unified into "one base map and multiple layers", and the wall chart can be used for command, scientific decision-making and closed-loop promotion, and the city can be managed "like embroidery" gradually.

Generally speaking, all kinds of big data analysis applications can be divided into three levels. The first layer is descriptive analysis application, which refers to summarizing and extracting relevant information and knowledge from big data to help people analyze what happened and present the development process of things. For example, big data applications in epidemic prevention and control in COVID-19 basically belong to this category: community control has "health code", grass-roots prevention and control has "close contact meter", and there are "three-color code" for resuming work and production, as well as mobile communication operators’ 14-day mobile phone main activity trajectory data query. It can be said that big data technology has become one of the important scientific and technological means for epidemic prevention and control in COVID-19.

The second layer is the application of predictive analysis, which refers to analyzing the relationship and development mode between things from big data, and predicting the development trend of things accordingly. Taking the prevention and control of epidemic situation in COVID-19 as an example, by integrating the location data of operators and Internet companies, it can quantitatively support the analysis and judgment of population flow trend, which is convenient for forecasting development trend, analyzing regional risks and realizing accurate prevention and control.

The third layer is the application of decision analysis, which refers to the analysis of the effects of different decisions and the guidance and optimization of decisions on the basis of the first two levels. Decision-making analysis emphasizes causality, not only "knowing why" but also "knowing why". For example, the organic combination of big data and epidemiology can further accurately estimate the number of high-risk areas and high-risk personnel on the basis of macro and overall trend research, and provide more scientific and accurate decision-making basis for medical resources, materials and prevention and control measures.

Big data infrastructure construction can be expected in the future.

After active exploration and practice in recent years, China has made remarkable progress in big data technology, industry and application. At the same time, the integration of big data and next-generation information technologies such as artificial intelligence, blockchain and Internet of Things has opened up more room for progress. Among them, considerable progress has also been made in independent innovation and research and development. We need to further strengthen independent research and development, especially concentrate resources to build an open source platform for independent innovation of the underlying technology.

Not long ago, the The Politburo Standing Committee (PSC) Conference emphasized speeding up the construction of new infrastructure such as 5G networks and data centers. Compared with traditional infrastructure construction, new infrastructure construction focuses on the new direction of industrial transformation and upgrading. Represented by big data, "new infrastructure" reflects the general trend of accelerating the development of high-end industries. Big data technology R&D personnel should seize the opportunity, do a good job in the integration of new technologies and empower the construction of "new infrastructure".

Big data is one of the important representative technologies of the global wave of digitalization, networking and intelligence. Our working style, lifestyle, connection mode and cooperation mode will be changed, optimized and perfected, and each of us will become a part of it and become a witness, witness and builder of the digital society.(author:Huang gang,Professor, Peking University Institute of Artificial Intelligence)
