    With the dream of "automobile power", he led the team to step into the "no man’s land" of scientific research again and again, overcome key core technologies, solve the problem of "stuck neck", and was determined to build "people’s car" with hard core "Chinese core".

    He and his colleagues are quite responsible, and it is difficult to attack the "core". They have successively completed the independent development and mass production of software and hardware of more than 30 controllers, and completed the loading application of 40 million domestic chips on the whole vehicle.

    Thanks to the efforts of him and his team, Wuling Hongguang MINIEV, known as the "people’s scooter" and the world’s single-model sales champion of new energy vehicles for seven times, has increased the localization rate of chips from 6% to 93% in three years.

    As a doctor of "returnees" majoring in combustion science, he has devoted himself to car-making for thirteen years, and always "burns" his burning dreams in the most efficient way in the process of transformation and cross-border.

    He is the "Eight Gui Model", the deputy general manager of the technical center of SAIC-GM-Wuling Automobile Co., Ltd. (hereinafter referred to as SAIC-GM-Wuling), the chief technology officer of control and software, and the deputy director of Guangxi New Energy Automobile Laboratory and professor-level senior engineer Liu Changye.

   "Black! Open up the second pulse of industrial governor. "

    "emergency! Urgent! "

    Put the hour hand back to the end of February 2022. Although it is early spring, it is still chilly. There is a tense atmosphere in SAIC-GM-Wuling. Due to the sudden interruption of the supply of imported chips, the steering controller of key components could not be supplied, and a large number of cars on the assembly line could not be off the assembly line.

    At that time, the "chip shortage" was sweeping the automobile industry. The price of some key components has skyrocketed. Although the price has doubled, it is still hard to find a "core", resulting in a shortage of controllers. SAIC-GM-Wuling introduced more than 40 measures to ensure supply before and after, but it still can’t completely solve the shortage of key components.

    "Before 2019, the controller was regarded as a’ black box’ by everyone, and it was purchased as a whole with parts. We don’t know its internal structure, let alone what chips are carried inside." Liu Changye said that it was not until the "chip shortage" spread in 2021 that enterprises deeply felt the pain of "sticking their necks".

    Production is facing stagnation, and engineers are in a hurry.

    I would rather fight hard than endure it. The grim situation has inspired everyone’s spirit of struggle and aroused the responsibility of "the more difficult it is, the more forward it is".

    "Black! It must be black! Key core technologies must be firmly in their own hands. " Liu Changye thought: "Perhaps the pain point of’ chip shortage’ is the key point to get through the second pulse of industry."

    As a result, the team immediately launched the "Black Box Action" to crack the internal mystery of the "black box" and determined to kill a bloody road on the unknown road of making domestic cars with domestic chips.

    The news of all parties was summarized in the technical center, and one of them attracted the attention of the team: a university in Shanghai with long-term and in-depth cooperation with SAIC-GM-Wuling has made a breakthrough in the application of domestic chips. Full of expectations, Liu Changye immediately went to Shanghai from Liuzhou with a research team of 20 people, and "chased the core" at full speed.

    "Our technology has no precedent for industrialization, and you are about to step into a’ no man’s land’." College experts told Liu Changye.

    The difficulties are far more than that. At that time, the COVID-19 epidemic in Shanghai was tight, so they had to move the scientific research equipment to the hotel, turning the hotel into a crucial place for the team, where they lived and ate. Lacking a testing ground, the underground parking lot became their testing ground.

    After fighting all night and repeated testing, the problems in the software code were found out one by one and corrected one by one. At the same time, Liu Changye also keeps in touch with suppliers, universities and Liuzhou base in production and logistics.

    Race against time. In just 8 days, the software development was completed, which solved the obstacle of related software from laboratory to industrialization. In another 6 days, 100% of the steering controller with domestic chips will be on the production line.

    This speed has shocked the industry.

    In the face of praise from all parties, Liu Changye, who started to set up a team to try to develop controllers at the end of 2019, was not satisfied. "We have mature and complete parts verification capabilities and technology industrialization capabilities, so that the technology of the institute can enter the market and enter thousands of households. There are still many ways to go."

    According to relevant data, in 2022, the global production will be reduced by 4.4 million vehicles due to chip shortage. The success of SAIC-GM-Wuling’s "Black-Breaking Action" ensured that 400,000 vehicles were successfully rolled off the assembly line, driving sales revenue to exceed 10 billion yuan.

    The "Operation Breaking the Black" has boosted everyone’s confidence. After that, Liu Changye led the team to further break through the technologies of software algorithm, domestic chip application and vehicle calibration, and successively completed the independent development and mass production of software and hardware of more than 30 controllers, realized the domestic substitution of 486 chips, and accumulated 40 million domestic chips in the vehicle. Loading application.

    Wade through the deep water and gnaw hard bones. SAIC-GM-Wuling not only solved its own technical problems, but also made domestic chips have rich application scenarios in the field of automobile manufacturing, which promoted the rapid upgrade iteration of domestic chips for vehicles and accelerated industrialization.

   "The software has no accidental failure"

    "There is no accidental failure in the software, and the probability of failure is 0, which is 100%." This sentence of Liu Changye is deeply in the heart of Zhang Zhongjun, the electronic architecture integration manager of SAIC-GM-Wuling Technology Center.

    In the traditional automobile manufacturing process, due to mechanical errors and other factors, there are occasional failures. In a new model development test, the body controller of one of hundreds of cars failed. As usual, Zhang Zhongjun attributed this to "accidental failure" and wrote it into the report.

    Unexpectedly, this was severely criticized by Liu Changye: "There is a problem with the software of this car, and it will definitely appear in other cars! We must find the cause of the problem and give a solution. "

    Although he didn’t quite agree with him, Zhang Zhongjun did as required. Because he knows that Liu Changye’s self-requirements and requirements for product quality are extremely strict.

    "We checked for a week and found that there was a mistake in the software program. We improved the scheme." Seeing the new report submitted by Zhang Zhongjun, Liu Changye finally smiled with satisfaction.

    The phrase "there is no accidental software failure" deeply affects the team-you must not let go of any suspicious problems.

    To overcome difficulties, we need courage and perseverance, and we need to find the right path.

    In November last year, when developing the key safety controller, Wang Wei, the test and experience manager, encountered an unprecedented problem. "This test is bulky and difficult. How to speed up the completion as soon as possible to reduce the supply pressure of the production line? How to solve the problem of high cost of collision test? This makes us feel at a loss. " He said.

    Just when Wang Wei was at a loss, Liu Changye told him, "Don’t be afraid of difficulties, do the right thing."

    Liu Changye broke through the traditional "hard-hitting" crash test method, took everyone to collect more than 30,000 sets of real vehicle data, conducted simulation tests through signal simulation, completed the target task in 10 days, and built a complete signal simulation test system.

    "Software testing is not only qualified acceptance, but also repeated verification in various complex environments, reverse analysis of all possibilities, and efforts to ensure safety and stability." Liu Changye’s words helped Wang Wei find the way to work and the mission of struggle.

    The ancients said, "Who dares to be wrong if the child rate is positive?" With Liu Changye leading by example and setting an example, the team worked as one, and the technical problems of "sticking the neck" were broken.

    "He proposed a long time ago to promote the localization of chips with decoupling thinking, eliminate the problem that chip software and hardware cannot be matched among different enterprises, and make the joint innovation of politics, production, learning, research and use more efficient and forward-looking. At present, the controller and chip application sub-laboratory of Guangxi New Energy Vehicle Laboratory is promoting scientific research innovation and technical iteration under such a concept. "

    "He has a huge knowledge reserve and is called a generalist in science. Once the data didn’t match, he personally deduced the mathematical formula. "

    "He is always full of energy. He forgets to eat and sleep when he does a project. He is often the last person to leave the office. Sometimes he replies to the questions raised by the team on WeChat at one or two in the morning."

    "He is rigorous and meticulous, pursuing Excellence, and his positive and optimistic scientific research attitude infects everyone in the team."

    ……

    In the interview, colleagues outlined the image of this "benchmarking" scientific research worker.

    In fact, Liu Changye is not a talented player born to build a car. From studying physics and combustion to studying engines, to focusing on the development of new energy vehicles and solving the problems of controller development … He constantly challenges himself, which is the intensive work and study for years. Those foreign language documents that have been turned over have been repeatedly tested for thousands of times. The lights that are always on in the office at night and the gray hair on his head are the testimony of the "post-80 s" technical expert’s diligent work and courage to climb the peak of science and technology.

   "Fighting spirit, changing the unknown"

    Interview with Liu Changye, we made an appointment at 8 pm. Through the window of Liu Changye’s office on the 5th floor of Wuling Hongguang Building of SAIC-GM, we can see that he is having a heated discussion with a group of people. It was not until half an hour later that the meeting ended that he came out and said apologetically, "Sorry to have kept you waiting!" "

    Walking into his office, there was a display screen for demonstrating PPT, two pieces of blue tooling, and various materials on the desktop … The most special thing was the form with a wall. "Key Controller Project Plan" and "Key Component Development Plan" … On the table, there are many key nodes, target tasks and development progress, and the time span is from 2020 to 2024.

    "When I have a sip of water, we’ll talk in two minutes." When we sit down, Liu Changye said. At this time, I saw Liu Changye’s eyes through black-rimmed glasses, which was a little tired.

    Before joining SAIC-GM-Wuling, Liu Changye studied physics and combustion, and went to Madrid University of Science and Technology and Delft University in the Netherlands to study. He was selected as the first batch of "National Project for Building High-level Universities" to jointly train doctoral students and went to Lund University in Sweden for further study.

    As we all know, new energy vehicles have no internal combustion engines. However, this expert who studies combustion is the first group of people who invested in the development of new energy vehicles by SAIC-GM-Wuling. Thanks to Liu Changye’s long-term study experience, he has developed his strong learning ability and logical thinking, which has become two sharp tools for him to carry out scientific research in the future. In his view, the internal logic of innovation and research and development are all interlinked.

    When studying in Sweden, the engine laboratory was next to his laboratory. "I was fascinated by the ingenious design of the engine in the laboratory. It was simply a perfect work of art." Speaking of which, Liu Changye’s eyes sparkled.

    After that, Liu Changye often went to the laboratory next door to observe. During the long-term exchanges, he deeply felt the gap between China and developed countries in car-making technology, and the seeds of dreams were quietly sprouting in his heart.

    "My parents are industrial workers and always respect and support my choices." The cold wind in Sweden gradually receded, and the moat of the castle began to shine, and winter went to spring. Standing at the crossroads of life, Liu Changye was a little confused in his heart until he met this engine. "I grew up in Liuzhou’s strong industrial and cultural atmosphere and watched the automobile industry surge. I am also the son of a worker, and I am always eager to use what I have learned. " Liu Changye immediately decided to go back to Liuzhou to work and devote himself to automobile research and development.

    In 2010, Liu Changye joined SAIC-GM-Wuling and was the second doctor recruited by the company.

    Nowadays, it has become the norm for "returnees" to return to their hometowns and doctors to enter the factory. Among the 4000 engineers in SAIC-GM-Wuling Technology Center, there are 26 doctors.

    Among the four apprentices Liu Changye is currently taking, there are two doctors. He also integrated the enlightened education of his parents into the process of mentoring.

    Alvin Wong, a post-90s doctor, is an expert in software testing and one of Liu Changye’s apprentices. "He always works late, but he never asks us to do the same." In Alvin Wong’s eyes, Liu Changye’s "being a teacher and a friend" is an example for learning and a yardstick for correcting mistakes.

    "When I first entered the company from campus, I always wanted to prove myself. In order to make an annual summary report, I want to present it in a bright way. " Alvin Wong said. However, Liu Changye told Alvin Wong that the road is simple, and it is not necessary to engage in fancy things in scientific research, but to be down-to-earth.

    Adhering to the fine tradition of "working hard and striving for self-improvement" and aiming at mastering key core technologies, SAIC-GM-Wuling is accelerating its global layout on the new track of new energy vehicles. A number of new energy vehicles, represented by Wuling Air ev, which shined brilliantly at the G20 Summit held in Bali, Indonesia in 2022, are shining frequently on the international stage with the expectation of Liu Changye and the team, and realizing the output of technology, standards and industrial chain.

    Under the leadership of Liu Changye, SAIC-GM-Wuling has set up a high-level scientific research team in the field of localization of automobile controllers and chips. On the stage of international competition, Liu Changye firmly believes that the self-controlled technology and reliable product quality will make the road for China automobile to "go out to sea" wider and flatter.

    In Kan Kan, Liu Changye described his dream of "automobile power".

    "Sorry, actually, I haven’t had dinner yet, and my brain can’t turn around …" At the end of our interview, Liu Changye said apologetically again. Only then did we notice that the sweets and biscuits on the table were used to satisfy his hunger when he was busy.

    Fighting spirit, changing the unknown.

    Out of Liu Changye’s office, there is such a sentence printed on the head-on wall. Looking back on the interviews in the past few days, from Liu Changye and his team, we can see the hope and confidence of China automobile industry to lead the world in the new energy track. (Li Bin Rongyao)

The oil car is BMW 3 Series, and the control is still much worse. The body of the pit is too much and too soft." This shows that he has some room for expectation and improvement in vehicle handling.

　　For goods with a value of 980,000 yuan, I bought a courier service with a value of 20,000 yuan. After receiving the goods, I found that the goods were damaged, and the maintenance cost was more than 10,000 yuan. The courier company said that it could only compensate 250 yuan.

　　The Beijing Youth Daily reporter visited and found that the default consumer agreed to its terms, the customer service of the express delivery company could not explain the specific compensation standard, and refused to undertake high-priced goods, which were almost common phenomena in the express delivery industry.

　　phenomenon

　　It is not a case that the loss of express mail is not compensated according to the premium.

　　Many companies do not undertake high-priced goods.

　　Mr. Zhong from Beijing sent a medical device worth 980,000 yuan to Nanning by SF Express. He deliberately chose the insured price of 20,000 yuan, and the insured fee was 100 yuan. When signing, it was found that the package was damaged and the shell was deformed. If it is repaired, it will cost more than 10,000 yuan. Mr. Zhong thought that the insured amount of 20,000 yuan could fully cover the maintenance cost. After Mr. Zhong provided the invoice of the equipment and the maintenance documents, SF said that it could compensate, but only 250 yuan.

　　Mr. Zhong’s experience is not a case. Ms. Jiang from Nanjing sent goods worth 622,000 yuan from Inner Mongolia to Nanjing by SF Express, and chose the insured price of 20,100 yuan. As a result, accidental damage occurred, and the maintenance price was 12,000 yuan. SF’s reply was compensation of 389 yuan.

　　Mr. Shi from Nantong, Jiangsu Province, sent the computer host to the customer through SF Express at a price of 4,000 yuan, which was damaged during the express delivery. Mr. Shi’s claim for compensation of 2,200 yuan was not supported, and SF Express could only compensate more than 800 yuan.

　　The reporter noticed that the standard of insured charges of express delivery companies is generally charged according to the insured amount or declared value of express mail from one thousandth to three thousandths. For express delivery with the insured price of 20,000 yuan, the courier company charges 20 yuan to 60 yuan. However, ladder pricing is also implemented. The higher the insured amount or declared value, the greater the proportion of insured fees. For example, Mr. Ru Zhong sent an express with the insured amount of 20,000 yuan, and charged the insured fee of 100 yuan.

　　Subsequently, the reporter consulted the SF customer service phone as a consumer. However, its customer service representative and the supervisor on duty did not give a clear explanation for its "insured compensation". The supervisor on duty even said that the insured compensation was explained by professionals, and they were not clear.

　　In addition, many users said that they were "agreed" to the compensation clause. The reporter of Beiqing Daily interviewed more than 50 citizens who frequently used express mail items, including some Taobao shopkeepers. They all said they knew the "guaranteed price" service, and more than 50% of the respondents said they had used this service. But for the compensation clause, they have never understood it. "Isn’t it full compensation?" Most interviewees expressed surprise after hearing the above cases.

　　At the same time, the reporter consulted the customer service of several express delivery companies and found that the final operation and explanation of express delivery insurance are at the terminal outlets, and the users need to negotiate with the outlets. When the reporter called some express outlets such as Zhongtong, Shentong and Yunda, when he learned that the items being delivered were computers, precious metal jewelry or works of art, the courier said that such goods could not be received and sent. "If you must send it, we can’t bear the loss of damage in the process." A courier of Zhongtong said.

　　The reporter of Beiqing Daily learned from the person in charge of some express outlets that even if the expensive goods are insured, the amount of compensation after problems is limited, and there is no guarantee that they will be fully compensated. Many companies also have regulations on the value of single-ticket express delivery. The reporter of Beiqing Daily inquired about the terms of a number of express delivery companies and found that the value of EMS standard express single items does not exceed 50,000 yuan, and the value of express parcels does not exceed 20,000 yuan; The value of one-piece express delivery of Yuantong and Zhongtong shall not exceed 30,000 yuan; The upper limit of the actual value of Shentong’s insured express delivery is 20,000 yuan.

　　survey

　　The word "proportion" in the clause

　　The amount of insured compensation has been greatly reduced

　　Although it cost extra money to insure the price, once compensation is needed, it is not based on the insured amount. Is this the unspoken rule of the express delivery industry, just like the loss of uninsured express mail can only compensate N times the freight?

　　The reporter of Beiqing Daily found that not all express delivery companies are like this. The reporter of Beiqing Daily inquired about the Express Service Agreement of SF Express, Yuantong, Zhongtong, Shentong, Yunda and EMS, and each company has clear regulations on the compensation method for insured express mail. Generally speaking, most companies implement "if the express mail is lost, damaged or short, compensation shall be made according to the actual value, and the maximum amount shall not exceed the insured amount of the express mail". A few companies will refund the premium on this basis.

　　According to the terms of the above express delivery company, if the insured express is damaged, it will be compensated according to the actual loss. For example, if a computer with an insured price of 10,000 yuan is damaged when it arrives, and the maintenance needs 2,000 yuan, then the courier company with the above terms will pay 2,000 yuan. This is more in line with the general public’s understanding of "insured price".

　　So why didn’t SF do this? The reporter of Beiqing Daily found that in SF’s terms, the expression of compensation for insured express mail is: "SF will compensate you according to the proportion of insured amount and actual loss in case of damage or shortage, and the maximum loss of consigned goods shall not exceed the declared value of insured price when you consign them."

　　Regarding the concept of "proportion" in the clause, Beiqing Daily reporter consulted its customer service as a customer. However, the customer service of SF Express said that there will be a staff member specially responsible for compensation to contact the reporter. As of press time, the reporter of Beiqing Daily did not receive a call from SF.

　　Previously, SF Express Commissioner replied to the media that there are two rules for "insured" compensation: "full amount" and "insufficient amount". "For example, in ‘ Full amount ’ In the case of insurance, if the value of the goods is 100,000 yuan, you have insured 100,000 yuan, and the later damage maintenance cost is 10,000 yuan. Under normal circumstances, we can fully pay you 10,000 yuan here. If this item is worth 100,000 yuan, you have insured 10,000 yuan, which belongs to ‘ Not fully insured ’ The later maintenance cost is also 10,000 yuan, which will produce a compensation ratio, which is the amount you guarantee divided by the actual value of the item and then multiplied by your actual loss. "

　　According to SF’s calculation formula, the compensation amount = (insured amount/actual price) × maintenance cost. Take Mr. Shi’s computer as an example. For a computer with 10,000 yuan, the insured price is 4,000 yuan, and the maintenance cost is 2,200 yuan. Mr. Shi can get 2200×0.4, which is more than 800 yuan in compensation. Mr. Zhong’s 980,000-yuan medical device is insured at 20,000 yuan, which means the proportional coefficient is 2%. The maintenance cost of more than 10 thousand yuan is multiplied by this proportional coefficient, and the final amount is more than 200 yuan.

　　analyse

　　Is it reasonable and legal to pay in proportion?

　　The Postal Law is not the only criterion for judging disputes.

　　Although the terms of the courier company are like this, is such compensation reasonable and legal? The reporter of Beiqing Daily inquired about a number of laws, regulations and current standards, and found that there are mainly the Postal Law, the Provisional Regulations on Express Delivery and the national standards for Express Delivery Service.

　　Among them, Article 47 of China’s "Postal Law" stipulates that postal enterprises shall compensate for the loss of vouched mail according to the following provisions: if the insured vouched mail is lost or completely damaged, it shall be compensated according to the insured amount; If it is partially damaged or the internal parts are short, the actual loss of the mail shall be compensated according to the ratio of the insured amount to the total value of the mail.

　　In this regard, Chen Yinjiang, Deputy Secretary-General of china law society Consumer Protection Law Research Association, said that it is fair to compensate some damages according to the proportion of lost value, but it is often difficult to define the proportion of damages in reality. Although some items are partially damaged, they may not be used by consumers. Even if the courier company pays in proportion, the rights and interests of consumers are still not guaranteed. Therefore, it is best to have a clear agreement between the two parties in advance, and perform according to the agreement if there is a problem.

　　Liu Junhai, a professor at the Law School of Renmin University of China, said that the provisions of article 47 of the Postal Law related to "guaranteed price" were placed in Chapter V, while "express delivery business" was in Chapter VI, so the rules on guaranteed price of postal enterprises in Chapter V should not be extended to express delivery business in Chapter VI.

　　The reporter of Beiqing Daily inquired about the referee document network and found that Dawasang Zhou in Xining, Qinghai delivered 1 kg of Cordyceps sinensis through Xining Shentong, with a value of 300,000 yuan and an insured price of 5,000 yuan. As a result, the parcel was lost, and Dawasang Zhou claimed 300,000 yuan from Xining Shentong. After three trials, the case was finally judged, and Xining Shentong paid 240,000 yuan at the market price. The judgment of this case is based on the Postal Law and the Contract Law. It can be seen that the Postal Law is not the only criterion for judging disputes.

　　Expert: The default check violates consumers’ right to know and choose.

　　The reporter of Beiqing Daily found that nearly 80% of the respondents said that they did not know from what channel to look at the terms of the courier company. "Now all orders are placed online. I have seen the express delivery terms in the original handwritten form, and now I don’t know where to look." The owner of a Taobao shop said that at present, electronic forms are used, and there are no terms printed on them.

　　Did the courier company really not announce the terms? The reporter of Beiqing Daily used the mobile phone WeChat to log in to the "Sent Items" business pages of several courier companies, and found that the "Express Service Terms" were under the address filling directory of this page, and some of them also used fonts of other colors to indicate "eye-catching".

　　Then why didn’t so many people notice? The reporter of Beiqing Daily also noticed that this clause is checked by default, which is different from the compulsory reading of other online services. Even if the reporter of Beiqing Daily did not register, this clause has been checked. Only by clicking the default check box can you click to read the Express Service Terms.

　　In this regard, Chen Yinjiang, Deputy Secretary-General of china law society Consumer Protection Law Research Association, believes that there are no other laws and regulations that clearly stipulate the insured compensation for express delivery, and all express delivery companies have formulated their own compensation standards and printed them on express delivery orders by unilaterally formulating standard terms. However, the clauses listed by express delivery companies on the express delivery list obviously reduce their own responsibilities and exclude the rights of consumers, which are typical overlord clauses and have no legal effect. In addition, the default check is certainly unreasonable, infringing on consumers’ right to know and choose.

　　An IPhone +QQ music player+digital audio standing wave processor+world cable box, with a simple and unexpected combination scheme, won the attention of countless media, industry insiders and experienced fans at the 2017 Shanghai International HI-FI Audio Exhibition (SIAV), and stood out from the noisy exhibition with its shocking playing conclusion.

　　Genesis (Singapore) Technology Co., Ltd. and Xuran Group, following the discovery trip in Hai Yin, Guangzhou on April 16th, once again took advantage of the Shanghai International HIFI Exhibition to release the new digital recording and broadcasting method of "Discovery, New Sound Machine"-"Digital Audio Solution". Under the witness of more than 60 media, nearly 3,000 people in the industry and experienced friends, Xuran Group demonstrated to the media and the public how digital audio solutions can solve the pain points in the audio industry from the root and promote a great leap in sound quality.

　　Only IPhone +QQ music player +KEF speaker, such a simple digital audio playback scheme, after loading the digital audio solution, that is, the world cable box and digital audio standing wave processor, the sound quality can reach HI-END level. At the event site, we showed: IPhone +QQ music player +KEF speaker, and the comparison between the loading and unloading of the world cable box and the digital audio standing wave processor. The participants at the scene were deeply shocked by the conclusion of playing QQ music after loading the digital audio solution. Some people in the industry even felt that this would rewrite the history of the audio industry and was definitely a subversive innovation. The veteran enthusiasts at the scene even bluntly said that they "don’t have to buy any vinyl or CDs anymore", and even felt that their playing conclusion far exceeded the effect of CD playing, and they were willing to pay for such a conclusion. There is no doubt that the digital audio solution can greatly improve the sound quality of QQ music playback because of the empirical comparison on the spot and the reaction of the participants.

　　Does this mean that the emergence of digital audio solutions will activate the new commercial profit model of streaming media operation?

　　On-the-spot analysts pointed out that QQ music keeps up with the trend of the mobile digital era. It has invested heavily in software development and copyright purchase, but it has been in a downturn in the paid music market, mainly due to the bottleneck of the hardware of digital audio playback carrier in audio technology. The release of digital audio solution has solved this problem. The actual playing conclusion on the spot has confirmed that after the technical solution is loaded on Apple mobile phone, the playing conclusion of QQ music makes senior fans and insiders willing to pay for it.

　　Xuran Group is committed to the technical application and promotion of "Digital Audio Solution" in all fields of audio. This conference has invested more than 30 million application products to provide free experience, hoping to jointly explore and extend the commercial practice mode of this technology in the audio field through the experiences and ideas of relevant people in various fields. At the same time, a dedicated team tracks the experience feedback and provides an open platform and technical guidance scheme. In view of the mobile digital products such as mobile phones with the greatest consumption demand at present, the corresponding experience scheme of digital products is opened.

　　In addition, on May 20th, Xuran Group will hold an extended application release of "Digital Audio Solution" with the theme of "Opening the Gate of Digital Audio and Establishing a New Digital Audio Standard" in Rongchao Yinglong Building, Longgang District, Shenzhen, and we will continue to pay attention to it.

Choosing 7kW or 11kW for the zero-running charging pile depends on the actual AC charging power supported by your car. At present, most models of zero-running only support 7kW charging. Generally speaking, it is enough to choose 7kW. However, if you consider the need of upgrading and changing cars in the future and have applied for a 380V meter at home, you can also consider buying 11kW charging pile.

Comparative analysis of 7kW charging pile and 11kW charging pile for your reference:

Charging speed:

7kW charging pile: It belongs to the conventional household slow charging power, and can charge the vehicle about 7 kWh per hour. If the battery capacity of your vehicle is not particularly large and there is no special requirement for charging time, the 7kW charging pile can meet the daily charging needs.

11kW charging pile: The charging speed is relatively fast, and the charging amount per hour is more than that of 7kW charging pile. It is suitable for some users who want to charge more power in a short time. However, the premise is that the vehicle itself supports the charging power of 11kW. If the vehicle does not support it, the charging power will be limited and the charging speed of 11kW cannot be reached.

Installation conditions:

7kW charging pile: Generally speaking, the voltage of 220V can meet the use requirements of 7kW charging pile, and the requirements for the circuit are relatively low. It is relatively easy to install in most household electricity environments, and it is not necessary to carry out large-scale transformation of the circuit.

11kW charging pile: It usually needs 380V three-phase electricity to support its normal work. If your community or family does not have the power supply conditions of three-phase electricity, it may not be possible to install 11kW charging pile. When applying for the installation of charging piles, the power department will evaluate whether it can be installed according to your electricity consumption and the power facilities in the community.

Price cost:

7kW charging pile: The price is relatively cheap, and the cost of purchasing the charging pile equipment itself or in the installation process is relatively low. Moreover, due to its low power, in the process of daily use, the power consumption is relatively small, and the electricity expenditure is relatively small.

11kW charging pile: Due to its high power, the cost of equipment, materials and labor required for installation may be higher than that of 7kW charging pile. And in the process of use, higher power may lead to an increase in electricity consumption.

Future applicability:

7kW charging pile: It can basically meet the daily charging needs of most zero-sports cars, and most new energy vehicles on the market now support 7kW AC slow charging, with good compatibility. If you don’t plan to change vehicles frequently, or the future vehicle charging needs are similar to those of existing vehicles, 7kW charging pile is a safe choice.

11kW charging pile: It has better compatibility and flexibility. If you may replace different brands or models of new energy vehicles in the future, and these vehicles support higher power charging, then 11kW charging pile can better meet the future charging needs. When purchasing 11kW charging piles, pay attention to purchasing charging piles that can be compatible with 7kW. Many third-party charging piles can’t be compatible with 7kW. If it is necessary to be compatible with 7kW when changing models in the future, the charging power will be reduced to only 3.5kW, and the charging will be very slow. It is recommended to consider the nebula 11kW charging pile. Their 11kW is compatible with 7kW. If you are a Tesla (supporting 11kW) and want to change to a zero-run car (supporting 7kW), then only one pile will enable Tesla and zero-run to reach the highest charging power when charging, and one pile will be used as two.

To sum up, if you don’t require high charging speed, the power supply conditions in your area are suitable and you want to save costs, then 7kW charging pile is a good choice; If you are looking for faster charging speed, have the power supply conditions of 380V three-phase electricity, and are willing to bear higher equipment and installation costs, then 11kW charging pile may be more suitable for you.

The application process of household charging pile electric meter is as follows:

Preparation before application:

Material preparation:

Identity certificate: the applicant’s valid identity document, such as ID card. If the non-head of household applies, it is recommended to fill in the power of attorney and entrust the family to handle it. Both ID cards need to be prepared.

Parking space certificate:

Self-owned parking spaces need to provide proof of parking space ownership, such as real estate license, parking space purchase contract, etc.

A lease agreement should be prepared for renting a parking space, and the lease period should generally be more than one year (including one year).

Proof of car purchase: any one of the electric car purchase intention agreement, car purchase invoice, electric car driving license, etc. is used to prove that you own an electric car.

Property or related certificates: for the community owners, a written certificate that the property agrees to use the charging facilities for installation or an agreement on the use of the charging facilities for new energy vehicles is required; No property management area by the industry committee, neighborhood committees or neighborhood offices issued relevant certificates. The installation of charging piles in rural self-built houses requires the seal of the village Committee to agree to the construction opinions.

Determine the installation conditions:

Confirm that there is a power distribution room near the parking space, and there is a distribution box of the State Grid in the power distribution room, and there is space and capacity for installing electric meters.

Communicate with the property in advance to find out whether the charging pile can be installed in the residential capacity.

Application process:

Online application:

The provinces under the jurisdiction of the State Grid (North China, East China, Central China, Northeast China and Northwest China) download the "Online State Grid"; The provinces under the jurisdiction of China Southern Power Grid (Guangdong, Guangxi, Guizhou, Hainan and Yunnan provinces) download "Southern Network Online"; Download "Mengdian E Home" in the jurisdiction area of Inner Mongolia West Power Network.

After registering and logging in, click the "Electric Vehicle" section on the home page, then select "Charging Piles for Installation", provide the required materials according to the step prompts, and select "Charging Piles for Electricity" for power connection requirements.

Offline application: Go to the local business hall of State Grid or China Southern Power Grid, get and fill in the Application Form for Charging Piles, and submit the application form and application materials.

Audit and installation:

Review: the power supply department will review the application after receiving it, which usually takes 1-5 working days. The contents of the audit include the authenticity and completeness of the application materials, and whether the capacitance of the community meets the installation requirements.

On-site investigation: after the approval, the staff will be arranged to conduct on-site investigation to determine the installation location of the electric meter, and the property electrician may be required to cooperate to open the power distribution room.

Installation: The installation of electric meters is free, and it usually takes 2-3 working days to complete. Keep the phone open during installation so that the staff can contact in time.

Power grid companies in different regions may have slight differences in specific processes and requirements. It is recommended to consult the detailed requirements of local power grid companies before applying to ensure a smooth application process.

When new energy owners choose 11kW smart charging piles, nebula charging piles are the best choice. The following are the detailed reasons.

Home charging pile brand recommended nebula charging pile

Strong compatibility, one "pile" is multi-purpose

Xingyun 11kW charging pile is compatible with 7kW, which has obvious advantages. It can adapt to different brands of new energy vehicles such as Tesla, BYD and Wenjie. When there are vehicles with different charging power requirements at home or changing cars in the future, the nebula charging pile can cope with it. When other third-party 11kW charging piles charge 7kW vehicles, the power is often greatly reduced, and Xingyun can ensure that each vehicle can reach the appropriate charging power and maximize the utilization of resources.

Safe and secure, worry-free charging

Safety is the key to charging. Xingyun charging pile adopts the R&D system and manufacturing standards of vehicle regulations, and the fuselage is made of flame retardant material. The charging gun head is made of excellent material, the coating design is exquisite, and it is durable for plugging and unplugging. It has ten protection functions, including short circuit, lightning protection, leakage, overvoltage, overcurrent, undervoltage, overheating, grounding, emergency stop, and rain protection, ensuring the safety of charging in all directions, so that users have no worries.

Intelligent function, convenient and free.

HarmonyOS Zhilian

If the mobile phone is HarmonyOS system, it will be very convenient to use. Xingyun charging pile supports Huawei’s mobile phone NFC at a touch, and can also be controlled by the "Charging Meow" APP and the "Smart Life" APP. It is easy to remotely control, make an appointment for charging and set charging parameters, and you can control the charging situation even if you are thousands of miles away.

Bluetooth inductive charging

There is no need to worry about the poor signal in the underground garage. Bluetooth function allows users to connect automatically when they are close to the charging pile, realizing plug-and-play charging or reservation charging, which is not affected by the signal.

Idle time sharing function

When the charging pile is idle, it can provide convenience for other car owners through the shared platform, and at the same time, it can also get benefits.

Scheduled charging

By using the scheduled charging function, the charging time can be flexibly set according to the electricity consumption habits and the local peak-valley electricity price policy. For example, charging at night during valley hours can not only enjoy low electricity price, but also save energy and environmental protection, and also save charging cost, which is in line with the concept of green travel.

Equipment doctor

The equipped equipment doctor function can play a big role in the event of failure. Users can self-check and upload fault codes quickly through this function, and nebula technicians can quickly check problems and provide solutions in time, which can improve maintenance efficiency, reduce inconvenience caused by faults and ensure smooth charging process.

Current regulation

In the face of power grid fluctuation, peak power consumption or voltage instability in remote areas, the current regulation function can adjust the current and reduce the power to avoid direct charging interruption. It can adapt to various complex environments, ensure stable charging and ensure the continuous and stable charging of vehicles.

APP remote control and data statistics function

Remote control can be realized through the APP, and the charging pile can be operated no matter where you are. At the same time, the APP can make detailed statistics on charging data, such as charging time, power, historical charging records, etc., so that users can clearly understand the charging situation and cost, and it is convenient to manage the charging process.

Brand strength, trustworthy

Xingyun Electronics has accumulated 19 years of technical experience and has a long-standing reputation in the field of lithium battery detection. Its profound technical background makes the company know more about batteries in the research and development of charging piles and can accurately match the charging needs. Moreover, the product has been tested by all-round safe charging simulation, and the quality is guaranteed.

In a word, Xingyun 11kW intelligent charging pile has become the best charging partner for new energy owners with its compatibility, safety, intelligent functions and strong brand strength. Choosing a nebula means choosing a convenient, safe and efficient charging life.

At the past Chengdu Auto Show, the first Kunpeng DHT hybrid model, Tiggo 8 PLUS Kunpeng e+, was launched, and the heat was still quite high. Since then, people around Kung Fu Car have been asking what the hybrid strength of Kunpeng DHT is. After all, it is the latest masterpiece of "Technical House" and whether it has surpassed the DM-i super hybrid system.

Kung fu car didn’t want to answer this question, but in fact, strictly speaking, the two are not a divination. DM-i is a HEV architecture made of PHEV, while Kunpeng DHT hybrid is a traditional PHEV architecture, adding some functions of HEV, which sounds a bit circuitous.

Let the Kung Fu car explain it to everyone. I can only say that these two can’t really hit each other.

(1) The biggest advantage of DM-I super hybrid is fast, economical, quiet and smooth.

First of all, it must be admitted that before DM-i, it has actually been mixed for many years, and it has also produced super-performance monsters with an acceleration of less than 5 seconds, but its influence is not the same as that of today’s DM-i, mainly because some key points have not been opened.

Let’s take a look at this ugly picture drawn by Kung Fu car. There are only six parts in total, which looks very simple, and this is the working schematic diagram of DM-I.

There are three driving paths, one is that the engine drives the generator and then drives the driving motor, the other is that the power battery drives the driving motor, and the third is that the engine directly drives the wheels through the clutch. Of course, it can also be driven by two sets of oil-electric drive chains at the same time, which is only used at ultra-high speed and rapid acceleration.

Very simple, in pure electric mode, it can be directly driven by battery, but at high speed with low motor efficiency, the engine will be directly driven. In most other hybrid modes, the engine drives the motor to work through the generator.

This is actually what we are trying to get through. The engine is more often used as a "charging treasure". It only uses the boring head to drive the generator to generate electricity, and then the motor only uses the boring head to drive the wheels. If there is excess electricity, it will be delivered to the battery. In this mode, the function of the power battery is greatly weakened, and it becomes an "energy pool". Of course, another point is that the engine can have average performance but high efficiency. After all, its biggest function is to generate electricity.

When driving in urban areas, 99% of DM-i vehicles are driven by motors, while 88% and 82% of DM-i vehicles are driven by motors under NEDC and WLTC conditions respectively. In other words, if you drive in the city, it is basically equivalent to a tram.

And what are the advantages of motor drive? First of all, it is fast. After all, it can output the maximum torque in the first time. Taking Qin PLUS as an example, its 0-100km/h acceleration time is 7.3 seconds, which is definitely fast enough. In fact, it is enough to save, not to mention pure electric driving. The fuel consumption in the state of power loss is 3.8L/100km. After all, the thermal efficiency of the engine is as high as 43%, while the conversion efficiency of the generator and the driving motor is above 95%. Then there is quietness and smoothness, which is also the inherent advantage of motor drive. After all, the acceleration of motor is absolutely linear, and the noise is much smaller than that of an engine with unstable speed.

Of course, in addition to being fast, economical, quiet and smooth, the DM-i system also has an advantage of being "green". The advantage of being able to get a green card allows it to reduce the dimension and attack electric vehicles. After all, the DM-i model has a comprehensive cruising range of more than 1200 kilometers, and just refuel, which fundamentally eliminates mileage anxiety, but it can still get a green card.

(2) Kunpeng DHT hybrid, dual-motor drive is the highlight.

Kun Peng DHT hybrid is the only hybrid system driven by dual motors in its own brand. It uses a special hybrid gearbox with multiple gear ratios to coordinate the work of engine and motor.

The core of this system is its hybrid gearbox, in which the engine supports three-speed transmission, plus the generator and driving motor, its generator itself can be driven, which is equivalent to three power sources. They cross out 11 gears, which can adapt to various road conditions. At the same time, it can also work in nine working modes, such as single and double motor drive, extended range, parallel connection and direct engine drive. The official saying is "three gears, nine modes and eleven speeds".

Theoretically, when a car has enough gears, its work will be more precise. After all, different gears correspond to different road conditions, but at the same time, the problem is that its control will be more complicated. In addition, although more gears can make the power output smoother, it is the coupling of oil and electricity through the gearbox, and it is impossible to be smoother and more linear than pure electric drive.

According to the data released by Tiggo 8 PLUS Kunpeng e+, the output power of its 1.5T hybrid special engine is 115kW, the maximum output power of the four-wheel drive version is 330KW, and the maximum output torque is 510Nm, even the output power of the two-wheel drive version is 240KW. This is still very powerful. The 0-100km/h acceleration time of its four-wheel drive model is 4.9 seconds, which is quite powerful.

Although no specific data has been released, it is revealed that the loss of electricity and fuel consumption of Tiggo 8 PLUS Kunpeng e+ is also good. After all, it also has a generator and has its own "hematopoietic" ability.

However, Kung Fu car is not optimistic that its power loss and fuel consumption will reach the same level as DM-i, because this generator is used for both power generation and driving. Considering the arrangement of its own three engines and four engines, the power generation will not be too large, but the power consumption capacity is quite strong, and the power conservation capacity is naturally not as good as that of DM-i with simpler structure.

In fact, the architecture similar to Tiggo 8 PLUS Kunpeng e+ has already been done before. It has more advantages in performance, relatively insufficient power-saving ability and higher cost. The result proves that the market influence is limited.

(3) Is the competitor of DM-I actually a fuel car?

At present, Tiggo 8 PLUS Kunpeng e+ has not been listed yet, which is actually not suitable compared with DM-i, which has a large number of systems.

Moreover, in Kung Fu car’s view, the biggest rival of DM-i model is actually not other hybrid models, but fuel vehicles.

Because other hybrid models can’t compete with DM-i at all, take the Tiggo 8 PLUS Kunpeng e+ as an example. It has three motors plus an engine, plus a quite sophisticated hybrid special gearbox. The DM-i has only two motors and no gearbox.

Both of them have their own advantages. The performance of DM-i is better due to power loss and fuel consumption, while that of Kun Peng DHT is stronger, but the cost of DM-i is much lower. It can make a hybrid car with a size close to Class B reach 100,000, which is unimaginable for Kun Peng DHT. And the simpler the architecture and the simpler the control logic, the less likely it is to go wrong, which is also common sense.

Furthermore, even if the architecture similar to DM-i can be achieved, it can’t be beaten. After all, in a world dominated by electricity, our advantages are too great. It is one of the largest power battery manufacturers, and also an excellent motor manufacturer. It is also a self-developed control chip, and its core technologies are still at an excellent level. If it is to fight for costs, other manufacturers have nowhere to start.

Therefore, if other hybrid cars want to compete with DM-i, I’m afraid they can only eat some relatively niche markets. For example, I don’t value price and reliability, so I want to speed up for a few seconds. Or the brand blessing is relatively large, and users are more willing to pay a premium. Even if the completion is not as good as DM-i and the price is higher, users are willing to pay the bill, but these are a minority after all. At least for now, DM-i is completely sweeping in the hybrid market.

And if you want to say that the model with the same dimension PK as DM-i is actually a fuel vehicle. After all, the fuel truck has simpler structure and more mature technology. Although the acceleration is not fast enough, smooth enough and quiet enough, many people don’t care so much about it. As for the higher fuel consumption, it can be offset by the difference in car prices.

Therefore, after DM-i came out, it has been promoting the subversive of fuel vehicles. This is its goal, that is, to change people’s car habits and make them pay more attention to driving experience, so as to tilt towards hybrid cars.

The voice of Kunpeng DHT is very high, but now it can’t compete with DM-I. It has its own advantages, for example, the engine has three gears, and dual motors can work with the engine at the same time to achieve stronger performance. However, its structure and control logic are a little too complicated, which is a great test for its working stability and will also push up the cost.

Therefore, the DM-i model with high probability will still be killed. As for Kunpeng DHT, let’s wait for it to be officially listed.

At the Guangzhou Auto Show in 2024, the third generation of Chang ‘an was unveiled with a brand-new upgrade, and once again it used countless strengths. After 12 years of precipitation and three generations of evolution, this "national family sedan" has become a star model at the exhibition with its dynamic design, strong power and super high cost performance. In October, the sales volume of Yidong series was as high as 16,818 vehicles per month, which was enhanced by the reputation and trust of 1.7 million users. Next, let’s deeply analyze this "light of family car" from multiple angles to see why it can stand out in the fierce competition market!

Avant-garde appearance: the design is dynamic and full of trends.

The third generation of Chang ‘an Yidong redefines the aesthetics of sedan chair with a brand-new design language. The front face adopts a V-shaped transverse borderless grille, which has a wide visual effect and a more refined overall shape with the source of star energy. The hidden door handle becomes the finishing touch. It is integrated with the car body when unlocked, and automatically pops up after unlocking, which not only enhances the sense of technology, but also effectively reduces the wind resistance coefficient.

Intelligent interior: the sense of technology is bursting and the operation is convenient.

Entering the car, the third generation of escape brings a double feast of vision and touch. The center console adopts the leading "double smart big screen" layout at the same level-the 13.2-inch vertical touch screen and the 10.25-inch full LCD instrument panel complement each other. The central control screen accounts for 88%, and the information display is more intuitive and comprehensive, so the owner can control the whole situation at a glance.

In addition, the instrument cluster is widened horizontally and close to the center of driving vision, which can display media, telephone, navigation and other information synchronously. This dual-screen interactive design not only optimizes the driving experience, but also creates a strong technological atmosphere, which makes people feel like they are in the future cockpit.

AI Super Brain Ann: Intelligent Driving Butler, On Call

The third generation of Yidong’s intelligent technology is not only a hardware upgrade, but also a qualitative leap in AI intelligent voice assistant. The newly equipped AI Super Brain Xiao ‘an can not only complete conventional car control, music playback, navigation and other operations, but also bring a more accurate and rapid interactive experience with the deep integration of large model technology. It is worth mentioning that AI Super Brain Ann also supports communication in specific scenes, making it your "knowledgeable person" travel partner. Whether you want to know the weather, recommend restaurants, or inquire about knowledge, it can respond quickly and truly realize the leap-forward upgrade from driving housekeeper to travel think tank.

Comfortable driving: specially designed for Chinese people, with first-class sitting feeling.

In the seat design, the third generation of Changan Yidong adopted the microfiber zero-pressure 3.0 cloud seat, which was tailored for Chinese people through the analysis of 100,000 Asian body data and more than 200 times of dynamic and static optimization. The 3D wing support design provides better wrapping, which can bring excellent comfort whether it is short-distance travel or long-distance travel.

In addition, the embracing suspended center console is matched with the suspended IP laminated shape, which enhances the sense of space and luxury atmosphere inside the car. With the addition of red interior color matching and simple wood decorative board, modern home style is introduced into the car, which is both warm and scientific.

The whole system is standard, and the configuration is full of sincerity.

The configuration of the third generation of Yidong is even more sincere. Functions such as, 540 panoramic image, and electric sunroof are already standard, and advanced functions such as inductive tailgate and PM2.5+ activated carbon air filtration system also appear directly in the entry-level models. This configuration strategy of "all systems are equipped as standard" is undoubtedly very attractive for home users.

In particular, the 540 panoramic image system can provide a comprehensive view in complex road conditions or parking lots, greatly enhancing the confidence of drivers and further enhancing driving safety.

Strong power: Blue Whale 1.5T+7DCT combination, with both performance and efficiency.

Power system has always been a highlight of the third generation of escape. It is equipped with the NE1.5T high-pressure direct injection engine of Blue Whale, with the maximum power of 125kW and the maximum torque of 260N·m, and the power output is smooth and strong. The measured acceleration of 0-100km/h takes only 9.1 seconds, and the maximum speed can reach 200km/h, which fully meets the needs of family car and driving pleasure.

Comprehensive protection: leading security performance at the same level

Safety is the core requirement of family cars, and the third generation of Yidong is leading in this respect. The car body is designed with "Ark Cage" structure, with 70% high-strength steel, and the highest strength reaches 1500Mpa. With the unique "vertical 5 vertical 5 horizontal" safety structure layout at the same level, it provides rock-solid protection for drivers and passengers.

Spacious space: meet the travel needs of the whole family

As a family car, space performance is the most important. Chang ‘an’s third-generation escape car body has a size of 4770×1840×1440mm and a wheelbase of 2765mm, and the rear leg and head space are spacious and comfortable, so it won’t feel depressed even if you ride for a long time. The design of the hatchback tailgate is the icing on the cake. The opening of the trunk is larger, and the storage flexibility is greatly improved, which can be easily handled for daily shopping or long-distance travel.

Summary: Ideal family car, all-round performance exceeds expectations.

With its dynamic appearance, comfortable interior, intelligent technology configuration and strong power, the third generation of Yi Dong in Chang ‘an has become a new benchmark of "National Family Car".
