　　In order to further promote the upgrading of economic industries, the state has put forward a supply-side reform plan to improve the quality and efficiency of the supply system. Product quality depends to a great extent on the level of product research and development and innovation, and is reflected in factors such as brand awareness. Therefore, the overall improvement of product quality to be achieved by supply-side structural reform is closely related to the intellectual property system. However, the Blue Book of Rule of Law (2017) recently released by the Chinese Academy of Social Sciences reveals that the overall quality of China’s product supply is not high and the degree of innovation is insufficient. China’s intellectual property rights still have many problems, such as low quality, insufficient protection and high protection cost, which seriously restrict the innovation of enterprises and the improvement of product quality. Therefore, it is necessary to further improve the intellectual property system and promote the realization of the purpose of supply-side reform.

　　Only 4.1% of enterprises invested more than 5 million in R&D.

　　According to the Blue Book of Rule of Law, through the investigation of the average investment in R&D projects of more than 7,000 enterprises, it is found that the majority (67%) of enterprises invest less than 1 million yuan in R&D funds, and only 4.1% of enterprises invest more than 5 million yuan. The investigation on the patent R&D cycle of enterprises shows that 23.2% of enterprises have a R&D cycle of one year or less, 44.1% have a R&D cycle of one to two years, accounting for 67.3% in total; 6.2% are really willing to carry out long-term research and development for more than three years. This shows that most enterprises are unwilling to spend too long on R&D activities.

　　The Blue Book points out that technological innovation determines the core competitiveness of enterprises. Although technological innovation requires capital investment, it will also generate huge returns. The reluctance of enterprises to invest more funds is a problem that needs reflection and improvement in the field of technological innovation. At the same time, the technological innovation ability of a country or enterprise determines the product supply ability to a certain extent. The ongoing supply-side structural reform in China is precisely to find ways to further enhance the core technological ability of China enterprises’ products and comprehensively enhance their brand reputation. Therefore, it is an important task to further improve the intellectual property protection system and help supply-side reform.

　　The number of patent applications is rampant and the utilization rate is not high.

　　The number of invention patent applications in China has maintained a steady growth trend. According to the data released by China National Intellectual Property Administration in 2015, China Intellectual Property Office accepted 1.102 million invention patent applications in 2015, up 18.7% year-on-year, ranking first in the world for five consecutive years. From the perspective of the number of patent applications, it seems that the innovation ability of China enterprises should rank first in the world. However, from the perspective of the quality of patent applications, this is not the case. No matter in the field of consumer goods or high-tech products, there is still a certain gap between the innovation ability and supply ability of China enterprises and their international counterparts. The innovation ability of enterprises in China is not proportional to the increasing number of patent applications.

　　However, the Blue Book of Rule of Law reveals that a large number of patents applied by enterprises have not really been used to improve product quality. According to China’s patent law, the protection period of China’s invention patent is 20 years, and the protection period of utility model and design patent is 10 years. However, in most cases, the patentee will give up the patent halfway. The Annual Report of Effective Patents in China in 2014 shows that the average service life of domestic invention patents is 3.8 years, utility model patents are 3.5 years and design patents are 3.2 years. However, only 0.02% of inventions, 1.1% of utility models, and 0.5% of designs actually reached the longest service life. The above data show that the vast majority of patents applied for in China have not really been put into use.

　　In addition, the implementation rate of patent licensing can also reflect the actual use of patents. From 2012 to 2014, 2,787,707 domestic patents were granted nationwide, and only 56,067 patent licensing contracts were signed, accounting for only 2% of the authorized patents. This data also reflects that most patents have not really been put into use.

　　Therefore, the patent application of enterprises and the product supply capacity of enterprises cannot be directly equated. In fact, in the existing system, the important index to evaluate the scientific and technological innovation ability of the government or enterprises is still the number of patents, such as: enterprises need patents to enjoy many preferential welfare policies; Enterprises need patent indicators to reduce or exempt taxes and apply for high-tech enterprise certification; Many places and units also need patents for talent introduction and talent evaluation. Obviously, applying for a patent can meet various interests. In addition, in many places, in order to strive for an advanced number of patent applications, bonuses are awarded to enterprises applying for patents through so-called incentive measures, which further leads to the proliferation of patent applications.

　　Seven adults think that the level of intellectual property protection needs to be strengthened.

　　According to the introduction of the Blue Book of Rule of Law, 8,938 people were surveyed with the title of "Evaluation of Intellectual Property Protection Level in China". On the whole, 67% of the respondents thought that the level of intellectual property protection in China needed to be strengthened gradually, even 24.4% thought it needed to be greatly strengthened, and only 7.2% thought it was more appropriate. It is not difficult to see from the survey results that the level of intellectual property protection in China needs to be further improved.

　　In fact, what choices do enterprises make — — Are you committed to your own innovation or imitation and plagiarism — — To a large extent depends on the analysis of costs and benefits.

　　For a long time, the level of intellectual property protection in China is too low, which makes many enterprises reluctant to innovate in the process of product supply, but more willing to imitate and copy. In the litigation of damages for patent infringement cases, 97.25% of the cases are subject to the standard of "statutory compensation", and the average compensation amount is only 79,600 yuan. In contrast, the average amount of patent litigation compensation in the United States from 2007 to 2012 was as high as 29.4 million yuan. In trademark infringement cases, the average amount of compensation awarded by the court is 62,000 yuan, which is also out of proportion to the huge efforts made by trademark operators to maintain their brands for a long time. The low amount of compensation for intellectual property infringement cases has contributed to the formation of this situation: innovators need to spend a lot of financial resources and efforts to make a difference in the pursuit of product quality, and infringers can "copy" it at a low cost. Therefore, the imitation trace is heavy in the supply of various products in China, the innovation ability is insufficient, and the number of intellectual property disputes remains high.

　　It is suggested that the punitive damages system should be fully introduced.

　　Supply-side reform is inseparable from intellectual property rights. Only by perfecting the intellectual property rights system can the real supply-side reform be realized. Based on the aforementioned problems existing in the above-mentioned intellectual property system, the Blue Book proposes to improve the intellectual property evaluation system and realize the change of supply side from quantity to quality. In the process of adjusting the patent quality evaluation system, the original patent quantification index should be adjusted to the actual contribution value of patents to improving product supply. Whether it involves the identification of high-tech enterprises, tax relief for high-tech enterprises, reduction of patent application fees, and related incentives for enterprise inventions and creations, it is necessary to cancel the original provisions on patent quantification, and take whether patents are actually used, the use effect, and the actual contribution value to product supply as evaluation indicators. In a series of documents that need to be submitted by enterprises, it is necessary to submit documents that patents play a practical role in product supply besides patent certificates.

　　The Blue Book also suggests increasing the cost of intellectual property infringement and realizing the transformation of the supply side from imitation to innovation. Although the statutory compensation limit was raised from 500,000 yuan to 1 million yuan when the Patent Law was revised in 2008, the existing compensation system still does not have enough deterrent effect on intellectual property infringement, and it is difficult to play an effective guarantee for innovation. Therefore, it is necessary to introduce the "punitive damages system" into the intellectual property law.

　　At the same time, reduce the cost of intellectual property protection and provide legal guarantee for continuous innovation on the supply side. In order to give patent applicants clear expectations and reduce the costs and risks caused by uncertain expectations, it is necessary for the patent law to clearly regulate the patent application cycle. Compared with other types, the process of invention patent is the most complicated because it involves substantive examination. It is necessary for the patent law to clearly regulate the time limit for applying for substantive examination and the time limit for examination results, and if it involves submitting corrected materials, it is also necessary to regulate the time for correction. At the same time, the time limit for the examination results of utility model and design patents is clearly regulated. In this way, enterprises will have a relatively clear expectation and evaluation of future risks in the process of technological upgrading and transformation, and minimize the costs and risks brought by intellectual property applications.

The exterior design of BMW i4 is full of futuristic feeling. The front face adopts family-style design style, and the iconic kidney-shaped air intake grille has been preserved, but it has been redesigned to incorporate more scientific and technological elements. The whole body line is smooth, showing the perfect combination of sports and luxury. In the rear part, the long and narrow LED taillights echo the body lines, which further enhances the recognition of the vehicle. The overall style not only retains the classic elements of BMW, but also adds a lot of innovative designs, which shows its unique charm as an electric vehicle.

The side lines of BMW i4 are smooth and dynamic, with a body size of 4785mm*1852mm*1455mm, a wheelbase of 2856mm, a front track of 1601mm and a rear track of 1630mm, providing passengers with spacious and comfortable interior space. The 18-inch rim is 245/45 R18 in front of tyre size and 255/45 R18 in rear of tyre size. With a sporty design, it shows the high performance of the car.

The interior design of BMW i4 embodies the perfect integration of modern luxury and technology. The center console is equipped with a 14.9-inch high-definition touch screen, which provides a convenient operation experience for drivers and passengers. The steering wheel is made of genuine leather, with delicate feel. It supports manual adjustment up and down and back and forth to meet the individual needs of different drivers. The car is also equipped with advanced speech recognition control system, which can realize the intelligent operation of multimedia system, navigation, telephone and air conditioning. In terms of seats, BMW i4 provides a variety of material choices, including imitation leather, genuine leather and fabric/suede mix, ensuring comfort and aesthetics. The main and co-pilot seats all support multi-directional adjustment, including front and rear adjustment, backrest adjustment, height adjustment, leg rest adjustment and lumbar support, which provides drivers with extremely high comfort. The front seats also have heating function to enhance the comfortable experience of driving in winter. In addition, the car is also equipped with the memory function of the driver’s seat and multiple USB and Type-C interfaces, providing passengers with a convenient charging and entertainment experience.

The motor of BMW i4 has a maximum power of 250kW and a maximum torque of 430Nm, which brings excellent power performance and rapid acceleration experience to drivers.

The evaluation of BMW i4 is very pertinent. He particularly emphasized the sound insulation effect, dynamic performance and exterior design of the vehicle, especially the presentation of volcanic red interior, which he thought was not inferior to the interior design of Mercedes-Benz’s sister. This fully proves the excellent performance of BMW i4 in quality and design.

The attention of pure electric vehicles of traditional car companies will be even more concerned than the new version of a car. In addition to feeling what manufacturers with a history of nearly 100 years have done in the new energy field, they also want to know what is the difference between the concept of building cars with new power brands. New energy vehicles attract consumers not only with pure electric energy, but with a brand-new way of travel, and look forward to the performance of Nissan Ariya ARIYA.

In October 2019, Nissan released the concept car Ariya at the Tokyo Motor Show, which is also the first model to use a new style logo. Today, nearly three years later, Nissan Ariya has been listed, and its appearance is almost exactly the same as that of the concept car.

The front face of V-motion design is still reflected in Ariya with sci-fi flavor. The fully enclosed China Net is believed to get a lot of return rate. Similarly, after buying this car, strangers will often ask: "How many kilometers can this car run?" "What kind of car is this?" .

The wheel eyebrows are connected with the lower edge of the whole car body, and the obvious division with the car body is like lifting the car. Fortunately, the car uses a brand-new wheel rim shape of tungsten steel color, so that the parts that are most likely to "play" maintain the height of the sci-fi appearance atmosphere.

The tail uses penetrating taillights, and the flat tail area is a test of Nissan’s spraying process. If you want to achieve the future effect, the mirror effect and flatness of the paint surface need to reach a high level.

There are two wheel hub shapes in Ariya. The high-end tire size is 255/45 R20, and the other three models are 235/55 R19. Both wheels are dark gray, just like the metal cross section after cutting.

Ariya’s pure black interior design uses gold decorative lines to divide the upper and lower parts. The size of the multimedia screen and instrument in the upper part is 12.3 inches, and the two screens are not in the same plane position, which is also the detail of Nissan. The reason for this design is to keep the instrument from being blocked, but after getting used to the multi-screen design, this stepped screen combination will be refreshing.

The related functions of air conditioning adopt touch buttons, which have vibration feedback after being pressed, and physical buttons such as volume adjustment and double flashing are perfectly hidden in the dividing line.

The movable armrest box and the penetrating platform are one of the biggest highlights of Ariya’s interior.

There are many possible combinations in the flexible space. The armrest box can move 15 cm, and the movement between the main driver and the auxiliary driver will become more calm.

However, the disadvantage is that it is impossible to temporarily store water bottles, handbags and other items at the feet of the co-driver, and there is the possibility that these items will slide to the main driver.

The details of the double-amplitude steering wheel are handled delicately, and the alignment mark is placed directly below.

All four models are equipped with L2-level assistance of ProPILOT system, full-speed adaptive cruise and other driving systems, and active safety systems such as lane departure warning, active braking and front collision warning are also standard.

The new car is built on the CMF-EV platform, which is jointly built by Nissan, Renault and Mitsubishi. Nissan Ariya, which is positioned in a compact SUV, is also the first domestic model of this platform.

Nissan Ariya will provide rear-drive and four-wheel drive modes, and a rear-drive SUV will fill my expectations for driving.

Ariya is equipped with Nissan’s self-developed EESM- electric excitation synchronous motor. According to official sources, the advantage of this power system is to give consideration to efficiency and performance.

The total power of the two-drive motor is 178kW, the total torque is 300N·m, and the cruising range of CLTC is 623km.

The total motor power of the four-wheel drive version is 320kW, the total torque is 600N·m, and the CLTC cruising range is 559km and the top version is 533km respectively.

The equipped batteries are all liquid-cooled ternary lithium batteries with a capacity of 90kWh.

Recommended model: Ariya ARIYA 2022 two-wheel drive long endurance top version

Reason: The four models of Nissan Ariya have the same battery capacity. Although the absolute power of the rear-drive version is slightly inferior, the characteristics of the motor also make the rear-drive and four-wheel drive only faster and faster, so riders with limited budget and no special requirements for four-wheel drive can safely choose the rear-drive version.

The configuration is almost the same as that of the top version, which is 12,000 yuan more than that of the low version, but the configuration of electric tailgate, 360-degree panoramic image, HUD head-up digital display and automatic anti-glare rearview mirror can be worth the fare of 12,000 yuan.

summary

The appearance of Nissan Ariya has refreshed my view of traditional manufacturers, which is less common than the scene of concept cars on the road. A rear-drive SUV with a 90-degree battery and a sci-fi appearance sounds very playable, but the price of 27.28-34.28 million yuan still needs comprehensive vehicle performance, and I look forward to Nissan Ariya’s performance in driving quality.

　　Zhongxin. com, Hangzhou, November 3 rd (Shao Yanfei, Fu Feiyang) A history of Chinese ceramics, half of which is in Zhejiang; A history of Zhejiang ceramics, half in Longquan. The traditional firing technique of Longquan celadon began in the Three Kingdoms and the Jin Dynasty, flourished in the Song and Yuan Dynasties, and reached its peak in the Southern Song Dynasty. It is a "cultural symbol" juxtaposed with Song Ci and Song Painting, and is also the first ceramic project selected in UNESCO’s Representative List of Intangible Cultural Heritage of Humanity.

　　"Longquan celadon is well deserved ‘ Porcelain sea pearl ’ , exchange and learn from each other ‘ Cultural emissary ’ 。” Dan Jixiang, president of China Cultural Relics Society, commented on Longquan celadon.

　　Recently, the 5th World Celadon Conference (hereinafter referred to as Celadon Conference) was held in Hangzhou. The reporter interviewed many experts and scholars, celadon craftsmen and celadon culture lovers from home and abroad to explore the story behind Longquan Celadon — — Since it was passed down more than 1600 years ago, why is the Millennium kiln fire endless?

　　The watch relay of generations

　　People are the key factor in the inheritance of a skill.

　　Weisyun Lo, a master of arts and crafts in China and a celadon craftsman born in 1962, is now training more than 30 apprentices. In his view, it is necessary not only to teach porcelain art, but also to inherit ingenuity. "Let more young people have creative enthusiasm for porcelain art, so as to avoid the talent gap and truly realize the inheritance and development of Longquan celadon."

　　In fact, Weisyun Lo himself became famous. His teacher, Xu Chaoxing, has more than 500 skill inheritors, and has trained three China arts and crafts masters, including Weisyun Lo. The reporter from Zhongxin. com learned that the older generation of celadon craftsmen attach great importance to the inheritance of skills. It is precisely because of their generosity that Longquan celadon can be succeeded.

　　"In this exhibition, I brought two works, Prosperous Life and Peace. The former conveys an all-inclusive aesthetic feeling with a round and thick shape, and the flower-drawing technology of the flourishing peony symbolizes the prosperity of the motherland; The latter combines the local cinnabar porcelain clay in Longquan with the moist plum green glaze, reflecting the minimalist beauty of Song Yun culture. " At the "Song Porcelain Dreaming of China" held in conjunction with this celadon conference — — At the celadon immersive interactive art exhibition, Xu Xing, a celadon craftsman born in 1988, said.

　　Xu Xingxiao said that nowadays, the "post-waves" are endless, and he is no longer the youngest among his peers. A large number of "post-90 s" celadon craftsmen are participating in various competitions and exhibitions with excellent works.

　　"I met Longquan celadon and was attracted by its literati temperament at first sight." Liu Hao, a post-90s celadon craftsman, said that Longquan celadon is in line with China’s traditional culture. He hoped to use celadon culture as a carrier to open another window for visitors to understand the cultural and social features of the Song Dynasty and appreciate colorful Chinese culture, and also to use the platform of the World Celadon Congress to let people feel the beauty of celadon and the prosperity of Song Wenhua more intuitively.

　　Since the Song Dynasty, Longquan celadon has been exported to more than 50 countries in Asia, Africa and Europe. In the reporter’s opinion, celadon culture crosses mountains and seas and goes to the world from a small town located in southwest Zhejiang, which requires celadon craftsmen and young and energetic celadon culture communicators.

　　Wu Aizhu, a celadon enthusiast and self-media blogger who has settled in Hangzhou, is attending the World Celadon Congress for the fifth time. "The color of Longquan celadon is very beautiful, and the exhibition of this celadon conference has made me feel refreshed." Wu Aizhu said that Hangzhou has a profound cultural heritage. Promoting and spreading Longquan celadon here is expected to gather more information flow, technology flow, commodity flow and talent flow in a short time.

　　"In the training of Longquan celadon-related industries, we can build a traditional apprenticeship system, social human resources training, and ‘ Three-track system ’ Training mode. At the same time, we can introduce high-end talents and gather scientific research strength by relying on collaborative innovation platform, Industry-University-Research platform, enterprise research institute, local research institute and various research bases. " Zhou Xiaofeng, deputy director and professor of lishui university Scientific Research and Local Cooperation Department, said.

　　During the opening ceremony of this year’s celadon conference, many celadon craftsmen from 1980s and 1990s participated in the activity of "Celadon UP" and had a lively discussion on the inheritance and development of Longquan celadon. Among them, some young celadon craftsmen talked to the older generation of celadon artists, exchanged creative experience and talked about future development. The "baton" of celadon culture is quietly passed on in gossip … …

　　Password of Common Wealth in Porcelain

　　One side’s industry is rich, and the other side’s people. Celadon is to Longquan what shoes and boots are to Wenzhou and private enterprises are to Zhejiang. Thousands of years of inheritance, the kiln fire does not go out. Entering Baoxi Township, Longquan City, 13 Gulong kilns are shining under the local repair and protection.

　　In recent years, Longquan has devoted itself to decoding the genes of celadon culture, telling the stories of celadon culture, and relying on the well-preserved Gulong kiln in Baoxi Township in Ming and Qing Dynasties, it has launched the traditional dragon kiln firing activity of "never extinguishing the kiln fire", and integrated it into the special exhibition experience links such as blessing ceremony, blessing ceremony, saggar opening, online auction and dragon kiln banquet, and combined the inheritance of celadon culture with the innovative development of rural tourism.

　　It is understood that the "Guyaoli B&B" in Baoxi Township is the first Longyao Celadon Living Museum B&B.. Here, visitors can see the well-preserved ancient kiln, experience the whole process of firing celadon by the ancients and enjoy the pleasure of making porcelain.

　　According to the data, there are more than 60 farmhouses and homestays in Baoxi Township, and a number of fine homestays such as "returning from strangers", "Ancient Kiln", "Fengshutan Farmhouse" and "Bageshu Starry Tent Hotel" have been cultivated successively, effectively promoting the development of regional tourism.

　　Take Xitou Village, Baoxi Township as an example. In recent years, the village has continuously amplified the driving role of celadon culture, effectively extended the consumption time of tourists, guided rural sages and villagers to develop cultural tourism formats, expanded the night economy, and created a "white+black" tourism consumption model. It is understood that it has achieved an average annual tourism income of more than 30 million yuan, and many derived formats have enabled villagers to increase their income and get rich at their doorstep.

　　Jin Chaojun, a wanderer who has been wandering outside for many years and has been in the shopping mall for a long time, resolutely chose to return to Xitou Village for a second venture in the year of no doubt. He said that the increase in operating income is only a part of rural revitalization. More importantly, the IP of "Never Extinguish Kiln Fire" has improved the cultural consciousness and cultural self-confidence of all villagers.

　　According to statistics, by 2021, Longquan celadon has more than 20,000 employees, and there are more than 2,600 celadon manufacturers and workshops, including 5 enterprises above designated size; There are many masters and young talents in celadon industry, and the annual main business income is 1.714 billion yuan. Longquan celadon industry has become one of the local pillar industries and plays an important role in promoting common prosperity.

　　"Longquan celadon industrial structure still has room for further optimization and adjustment, which can be subdivided into various fields — — Create more celadon works featuring handcraft, small batch, quality and artistry; Seek breakthroughs in the fields of building ceramics, industrial ceramics, daily-use ceramics, bioceramics and special ceramics, and enhance added value … …” Zhou Xiaofeng said that Longquan celadon should also build a complete industrial chain consisting of raw material production, material research and development, equipment manufacturing, creative design, creative production, product packaging, online marketing and cultural communication.

　　Iterative upgrading of porcelain-making technology

　　From "looked up to" ritual vessels to "flying into ordinary people’s homes" daily necessities, Longquan celadon’s porcelain-making technology is also constantly upgrading.

　　Recently, many experts, scholars and industry professionals from home and abroad enthusiastically discussed the development of Longquan celadon technology in a series of forums, such as the theme forum of "Celadon Rejuvenation and Common Prosperity", and actively offered suggestions.

　　"Now the development of Longquan celadon industry is in line with the times, sharing the new achievements of scientific and technological development, and surpassing the ancients in raw material processing, molding methods and kiln firing." Zhou Shaohua, a professor at Zhejiang University and chief expert of Longquan celadon industry, said.

　　Zhou Shaohua said that from the dragon kiln to the coal kiln, to the liquefied gas kiln and then to the electric mixing, the kiln and firing technology represented by the "celadon high-temperature kiln controlled by electric mixing computer automation" are enough to envy the ancients; The application of digital machine tool finishing technology to porcelain is not only accurate in modeling, but also low in cost and large in output, which is a typical example of "stones from other mountains can attack jade"

　　As it says, Longquan celadon with a long history has not been lost in the long river of time, and the key lies in technology and innovation — — In 2020, Longquan celadon work "Clover Burned Porcelain Fragrance Insertion" traveled around space on the Long March 5 B carrier rocket; In July this year, Longquan celadon screen fan appeared in Hangzhou National Edition Pavilion, and more than 200 layers of celadon screen fans showed the Song Yun Fenghua &hellip that has been flowing for thousands of years; …

　　"We have successfully established an innovative service platform for Longquan celadon sword industry in Zhejiang Province, and introduced advanced equipment such as intelligent kiln, four-axis linkage carving machine and glazing machine to solve the problems of mechanization, intelligence and batch production." Hu Xianru, director of Lishui Economic and Information Technology Bureau, said.

　　Development is always accompanied by challenges. In the process of iterative upgrading of Longquan celadon technology, there are also problems that need to be solved urgently.

　　"In terms of scientific and technological innovation, Longquan celadon scientific research investment ‘ Be short of money ’ The utilization rate of porcelain glaze is low, and the standardized production capacity needs to be improved. It is necessary to increase investment in related fields and continuously promote technological innovation. " Zhou Xiaofeng said.

　　In Zhou Xiaofeng’s view, the technological innovation and artistic innovation of Longquan celadon should be inherited, transformed, integrated and innovated with cultural confidence without giving up the celadon cultural genes. "Under the condition of modern technology and diversified aesthetic development, it is inevitable to moderately carry out technological innovation and artistic innovation on traditional techniques, but it is necessary to maintain ‘ Degree ’ And ‘ Special ’ Under the premise of realizing the modern performance of traditional celadon techniques and the intangible bearing of modern cultural and creative products. "

　　At present, the digital reform has also brought profound changes to Longquan celadon.

　　As one of the highlights of this celadon conference, "Song porcelain dreams of China" — — The immersive interactive art exhibition of celadon attracted many participants to stop and watch. Two large digital screens in the exhibition area reproduced the past lives of Longquan celadon from four sections: Life, Rite and Music, China and World.

　　"At present, we are focusing on building ‘ Longquan celadon non-legacy industry online ’ Digital application, build an online platform for celadon exhibition, build a celadon non-legacy resource library, classify, stereo record, graphic, audio and video, VR exhibition and other all-media materials into a unified database, and provide a good display and development platform for celadon craftsmen and their works. " The relevant person in charge of Longquan City said. (End)

　　Cctv newsA MV-22 Osprey transport plane of the US military crashed into the sea in the waters near Australia, and 23 people were rescued. Three people were declared dead after missing. In Okinawa, where the "Osprey" often flies overhead in Japan, this news has increased the anxiety and opposition of the local people.

Okinawa local people marched.

　　On the 8th, Esaki Tetsuma, Japan’s new Minister for Okinawa and Northern Territory Affairs, said in a rare way that the Japan-US Status Agreement, which stipulated the legal status of US troops stationed in Japan, "must be slightly revised".

　　At the press conference, Jiang Qi stressed, "Even if it takes more time, the government should fully understand the feelings of Okinawa residents. What it should say to the United States should be said."

　　However, as for the Japan-US Status Agreement, he said that "I am a layman" and did not talk about the specific direction of revision.

　　Japan and the United States signed the "Japan-US Status Agreement" in 1960, which stipulated that when civilian and military personnel employed in the US military base in Japan caused accidents or committed crimes while performing official duties, the US military stationed in Japan enjoyed priority jurisdiction, which was essentially equivalent to giving this group judicial immunity.

　　Whenever US military personnel commit crimes in Okinawa or an accident occurs in US military aircraft, the Japanese people’s call for amending the Japan-US Status Agreement is even louder.

　　However, under the pressure of the United States, the Japanese government has been holding a negative attitude towards amending the Japan-US Status Agreement for many years.

　　As the newly appointed Minister of Okinawa Affairs in the cabinet reshuffle on the 3rd of this month, Jiang Qi offered to amend the Japan-US Status Agreement, which was even called "rare" by the Japanese media. However, it is not clear whether Jiang Qi’s statement reflects the overall policy of Abe’s government.

How is your pure electric car experience in the cold winter?

The discount on battery life may not be the worst thing. Recently, more than a dozen Tesla owners in Canada have reported that even the air conditioner can’t be used in winter. Not only is the car frozen at a discount, but people are also frozen with a snot and tears.

Moreover, the basic things that can’t be heated in winter are heat pump air conditioners.

This is very strange. The high-efficiency and energy-saving advantages of heat pump air conditioners have not been brought into play, but they cannot be heated, which has attracted the doubts of some Canadian car owners and attracted the attention of Tesla’s R&D team. Musk said that this is a high priority for Tesla.

But even weirder, Musk said that the failure of heat pump air conditioner turned out to be a software problem, which can be completed by firmware update. Perhaps many people have never heard of it, and air conditioners still need OTA. However, after understanding the structure and working principle of Tesla heat pump air conditioner, we can find that this set of hardware can realize 12 different functions, and all the functions are controlled by software.

Therefore, the problem of Tesla heat pump air conditioning may really be a software problem.

So, how amazing is Tesla’s heat pump air conditioner? Why can’t refrigeration occur under extremely cold conditions? Can the industry solve this problem? After reading the patent of Tesla heat pump air conditioner and having a conversation with the Weiling engineer of Midea, the car found the answer to the question.

This month, countries in the northern hemisphere ushered in the coldest time since winter, and electric vehicles also entered the worst stage of the year.

Recently, Tesla owners in Canada reported that they were driving in an extremely cold environment and the heat pump air conditioner could not be used.

Twitter user @TSelvig said that when traveling that day, the temperature had dropped to-40 C. In this extremely cold weather, when he was driving Tesla Model Y, the heat pump air conditioner could not be used. After trying to restart the vehicle and call Tesla customer service, this problem still cannot be solved, and the owner is a few hours’ drive from the nearest service center, so it is impossible to drive without air conditioning.

In the end, the family switched to a fuel car.

Another Model Y owner @paateach has a richer experience. His Model Y has no warm air for two consecutive winters.

He tweeted that he lived in Saskatchewan, southern Canada, and in February last year, he encountered the situation that the heat pump air conditioner could not be used, and there was no warm air for a whole month. Later, Tesla replaced a group of super manifolds for him, and the heat pump air conditioner could be used at that time. However, by this winter, when the temperature dropped to -30℃, he once again encountered the situation that the heat pump air conditioner could not be used.

At that time, he photographed the prompt on the car screen: the cockpit climate control system needs maintenance, and the heating and cooling systems will be restricted or unusable.

Two car owners questioned Tesla: Why did Tesla’s heat pump air conditioner fail in extremely cold weather? Tesla has been repaired several times, why is the maintenance plan still invalid?

Some car owners even said that after this winter, they hope to sell their Tesla in exchange for a fuel car, at least there will be no air conditioning and heating failure.

Angie Dean, chairman of Tesla Owner’s Club in Alberta, Canada, said: "In Alberta and Saskatchewan, Canada, more than a dozen Tesla owners have experienced the problem that heat pump air conditioners cannot be used."

Just last week, the owner community Drive Tesla Canada tweeted @ Musk, asking him to comment on the heat pump problem. Musk replied to the tweet within 5 minutes, saying that maintaining the heat pump air conditioner has a very high priority. After 40 minutes, Musk said that the new firmware of heat pump air conditioner has been introduced to users.

It is quite curious that why the failure of heat pump air conditioner can be repaired by firmware update? In addition, after the firmware update is completed, there is still feedback from the owner that heating cannot be done. Is the firmware update useful?

In a patent document published by Tesla in 2019, the structure and operation mode of the heat pump air conditioning system were demonstrated. At the beginning of 2020, with the mass production of Model Y, this patent was also transformed into the mass production application of Tesla.

If you open the front case of Tesla, you can see the heat pump air conditioner and many pipes and harnesses. In fact, this is just the tip of the iceberg of the heat pump system. From the patent drawing, Tesla’s heat pump air conditioner has 11 main components, and is responsible for the thermal cycle of the whole vehicle, which can lead to different parts of the vehicle such as cockpit, battery pack and motor.

These main components are compressor, cabin condenser, cabin evaporator, battery system cooling device, cabin blower, motor liquid-cooled condenser, storage battery, three-way compressor air outlet, low-voltage electric cabin heater (PTC), recirculating air conditioner and heating.

Among the 11 main components, Tesla did not directly cancel the traditional PTC heating, but still equipped with a low-voltage PTC heating. However, due to the lack of power, this PTC heating device can not directly heat the cabin, but provides auxiliary heating when the heat pump system is insufficient.

Surprisingly, Tesla’s hardware can realize 12 different working modes, which are completed by different software scheduling.

Among these 12 working modes, there are only three modes in which heat pump participates. Heat pump participation in heating can be divided into pure heat pump mode and mixed heating mode. When the heat pump efficiency is high, the pure heat pump mode is activated, and when the efficiency is low, the mixed heating mode is activated. The heat pump can be mixed with PTC heating and can also be added to the evaporator for heating together.

In addition, the cabin and battery system can be heated simply by using the compressor and evaporator. In addition, the in-vehicle thermal circulation system can also realize the functions of cabin defogging, defrosting, dehumidification and so on.

A conclusion can be drawn here: it is indeed feasible to fix the problem of heat pump air conditioning through firmware update.

When there is nothing wrong with the hardware of the heat pump air conditioning system, the adjustment of the heat pump air conditioning system can be realized by adjusting the software scheduling in different environments.

As far as the heat pump system is concerned, there is a strong relationship between the efficiency of heating the cabin and the efficiency of the heat pump. Because the working principle of heat pump air conditioning is to exchange heat energy inside and outside the car.

Through the evaporator, the refrigerant can absorb heat from the external environment, and after the refrigerant in the car is liquefied, it releases heat, so that it can heat the cabin.

However, if the temperature of the external environment is lower, it is more difficult for the refrigerant to obtain heat from the external environment, which leads to the low heating efficiency of heat pump air conditioning in extremely cold environment.

Tesla also knows this obvious problem, so it adds auxiliary heating devices in addition to heat pump air conditioning.

Tesla drew a chart in the patent, which can explain the efficiency of heat pump air conditioning at different temperatures. The efficiency coefficient of heat pump air conditioning is expressed by COP(Coefficient of Performance). When COP=1, it means that the consumed electric energy is equal to the generated heat energy. When COP>1, the heat pump air conditioner is in the high efficiency area, which means that it can get more heat energy by consuming less electric energy.

As can be seen from Tesla’s chart, when the ambient temperature and battery temperature are lower than -20℃ at the same time, the efficiency of heat pump air conditioning will be very low, which is also considered as extremely cold temperature by Tesla, and there is no solution below this temperature. But at this time, just heat the battery, the COP value will increase, and the heating system can be used normally.

When COP=1, the heat pump air conditioner does not work and relies on evaporation to achieve heating. When COP≥1, the heat pump air conditioner will participate in heating, and the temperature needs to be above -10℃.

The second conclusion can be drawn here: if the weather outside is extremely cold, even if the firmware of the heat pump air conditioner is updated, the heating effect will still be poor. The solution is to heat the battery, or preheat it before going out.

However, under the tweet that Musk replied to the updated firmware, there are still many users who feedback that the vehicle still cannot heat.

Then, there is probably a hardware problem.

Tesla owner @paateach said on Twitter that his Tesla Model Y has been replaced with two super manifolds, including the sensor of heat pump air conditioner, expansion valve and refrigerant pipeline. The heating system can be used temporarily, but I am very worried that it may be damaged again.

Twitter user Tesla owner revealed the research and development story of heat pump air conditioner online. Recently, Tesla’s engineers in California and Alaska are testing heat pump air conditioners. The test results show that Tesla’s heat pump air conditioners can work normally below -30℃ because the heat pump air conditioners have two refrigerant cycles.

At the same time, engineers also found the problem: in extremely cold weather, the cover plate of the front air inlet will be frozen and damaged, which will lead to the inhalation of cold air during driving. Because the cold air temperature is too low, the sensor will report an error to the system after sensing it. At this time, the compressor will stop working and the heating will stop.

In order to solve this problem quickly, Tesla may start the compressor by software, temporarily avoiding the heating failure in extremely cold weather. But to solve this problem completely, Tesla may need to update some hardware later.

For the automotive industry, heat pump air conditioning is still a new thing, and Tesla Model Y was mass-produced in early 2020. Prior to this, pure electric vehicles generally used PTC to heat the interior of the car. But even under ideal conditions, the COP of PTC is 1. Low efficiency leads to very large electricity consumption for PTC heating, which further becomes a major factor affecting the battery life of electric vehicles in winter.

The efficient performance of heat pump air conditioning has attracted the attention of electric vehicle companies. In 2021, all new pure electric vehicles were basically upgraded from PTC heating to heat pump air conditioning. However, due to the limitation of refrigerant, when the temperature is below -10℃, the efficiency of heat pump will be greatly reduced. At this time, it is necessary to rely on PTC heating to heat vehicles.

For example, Tucki P5 is equipped with a heat pump air conditioner to achieve efficient heating, but it is also equipped with PTC. When the temperature is lower than -10℃, the vehicle will start PTC heating to heat the interior.

It can be said that Tucki P5 has solved the shortcomings of heat pump air conditioning to some extent, but it has not been completely solved.

Weiling, another new auto parts manufacturer, has solved the heating problem in extremely cold weather. Speaking of Weiling, maybe many friends in the automobile circle are no strangers. Weiling is a subsidiary of Midea Group, a domestic appliance head enterprise.

Last year, several auto parts announced by Weiling included automotive heat pump air conditioners.

At present, R134a(CH2FCF3, tetrafluoroethane) is usually used as the refrigerant for heat pump air conditioning, but when the outside temperature is low, the heating capacity is obviously attenuated. Therefore, there are explorations of mixed refrigerants in the industry, but the performance cannot be significantly improved.

The engineers of Weiling parts found another way, using carbon dioxide as refrigerant, and the heating efficiency was obviously improved at extremely cold temperatures.

Weiling’s rotary CO2 electric compressor can achieve a heating efficiency of COP=2 at -30℃. At the same time, the noise is low during operation and the overall design is lighter.

Engineer Weiling introduced that in extremely cold weather, users don’t need to "cover the quilt" to drive. At the same time, compared with traditional heat pump air conditioners, the heat pump with carbon dioxide as refrigerant can increase the cruising range of vehicles by up to 20%.

The CO2 electric compressor alone has 220 domestic invention patents and 14 international invention patents, and has completely independent intellectual property rights. At the same time, CO2, as a common greenhouse gas, is collected and used as a refrigerant, which also contributes to "carbon neutrality".

Last year, the heat pump air conditioning products of Midea Group Weiling components have been installed on pure electric brand vehicles such as Tucki and Weilai, which has become a microcosm of the rapid transformation of domestic component enterprises to electrification.

In 2020, Tesla put the heat pump air conditioner into a pure electric vehicle, which led the electric vehicle industry to take another step towards high efficiency. In just one year, by 2021, heat pump air conditioning has become the standard of high-end electric vehicles.

Obviously, the technology that will not be used in the era of fuel vehicles may be a huge innovation in the era of electric vehicles. In today’s increasingly fierce global competition for electric vehicles, there is still huge room for innovation in the field of electric vehicles.
