I just spent 270,000 yuan on the Han EV, and I am deeply impressed by the green brand car. I advise those who want to buy it to think twice, or it will be too late to regret it!

I bought Tang DM three years ago and Han EV this year. Now I feel too deeply about the "green brand car". There are three shortcomings of new energy vehicles that can only be felt after long-term use. Many car critics only say some known shortcomings, but some of them are not known at all.

Before answering whether I regret spending more than 200,000 yuan on a green car, let me briefly explain what a green car is.

Green brand vehicles include: pure trams, plug-in hybrid vehicles, oil-electric hybrid vehicles and extended-range electric vehicles.

Han EV, Tucki P7, and these cars belong to pure trams. Among them, China has the strongest support for pure trams, and the pure trams of its own brand have developed rapidly. Compared with the technical shortcomings of fuel vehicles in three major parts, they are currently in the leading position in the field of pure trams and Huawei in the technology of three electric power plants.

A pure electric vehicle refers to an electric vehicle that is completely driven by the power provided by the power battery. The vehicle-mounted power battery is the power source and the wheels are driven by the motor.

Tang DM, GTE, eRX5, these cars belong to plug-in hybrid cars, among which the hybrid models are the most and the technology is relatively mature.

A series of DM-i models will be launched in the future, which is a further upgrade of hybrid vehicles, making up for some technical shortcomings of hybrid vehicles before, making hybrid vehicles the most powerful competitive models of fuel vehicles.

Plug-in hybrid vehicle is a new energy vehicle between a pure tram and a fuel vehicle, which includes both the engine and transmission of a traditional car and the battery and motor of a pure electric vehicle.

Because the battery capacity is relatively large, it can be charged through the charging interface. It combines the advantages of pure trams, hybrid electric vehicles and extended-range electric vehicles, and can not only drive purely electrically, but also increase the continuous driving of vehicles through hybrid mode.

Rational ONE, Celeste SF5 (selected by Huawei) and Lantu FREE belong to extended-range electric vehicles, among which the sales volume is the highest, but due to the large body, the fuel consumption as a new energy vehicle has been high (about 10 liters), which has become the slot point.

When the battery of the extended-range electric vehicle is sufficient, the power battery drives the motor, and the engine does not participate in the work at this time; When the battery power consumption reaches a certain level, the engine starts to charge the power battery; When the battery is fully charged, the engine stops working again.

The biggest difference between the extended-range electric vehicle and the hybrid vehicle is that the engine of the hybrid vehicle participates in driving the vehicle, while the engine of the extended-range electric vehicle is only responsible for driving the generator to charge the battery, and does not participate in driving the vehicle throughout.

Dual-engine, CR-V hybrid and dual-engine, these vehicles belong to hybrid electric vehicles, among which hybrid electric vehicles mainly focus on harmony. They have developed early and well-stocked hybrid electric technology, and the technology is relatively perfect.

The hybrid electric vehicle is mainly driven by the traditional engine, but it is equipped with a second motor. When starting and accelerating, the vehicle is driven by the motor, which can reduce the fuel consumption. Compared with cars of the same size, the fuel consumption is lower and the power is stronger.

The battery capacity of the hybrid electric vehicle is small, so there is no need for external charging, and the engine can drive the generator to charge the battery. However, due to the small battery, the motor cannot drive the vehicle for a long time, so it is not as powerful as the plug-in hybrid vehicle.

After knowing what a "green car" is, I will share my feelings of driving Tang DM and Han EV, hoping to give some valuable information to people who want to buy a green car.

Now, new energy vehicles are the future development trend. All major car companies are launching their own new energy vehicles, and many companies are preparing to build cars across the border. This "car-building craze" has brought an illusion to our consumers, as if buying a "green brand car" now is the right choice.

I saw several big brothers in Northeast China among the owners of Han EV. They often complained that the battery of Han EV was seriously attenuated in winter, and the hidden door handle was easily frozen.

In fact, in the extremely cold area of Northeast China, battery decay and hidden door handles are not problems of Han EV, but problems that all new energy vehicles will encounter. They should know the disadvantages of pure trams before buying a car.

Of course, although they have some regrets about buying pure trams, it is not because Han EV is not good, but because in the extremely cold area of Northeast China, pure trams still cannot technically overcome the problem of battery attenuation.

First, it will reduce battery life and cause coke ovens; Second, battery decay is also a waste of resources. To put it bluntly, it costs 50 yuan for electricity and can only last 30 yuan.

Although I bought the first Tang DM in 2019 and the second Han EV in 2021, I still want to tell you that you should think twice about buying new energy vehicles at this stage. Not all regions and people are suitable for new energy vehicles.

I bought Tang DM in 2019, and I liked Tang’s design very much at that time. However, based on my understanding of the three major parts of fuel vehicles, I thought that Tang fuel version was not the best choice, so I thought about it between Tang EV and Tang DM for a long time.

At that time, my recognition of pure trams was relatively low, and I thought that the batteries of pure trams were easy to break down, expensive to replace and short in battery life. After comprehensive consideration, I chose Tang DM, but in the actual use process, I found that Tang DM relied heavily on charging piles, which caused some troubles.

Because Tang DM is a plug-in hybrid car, it usually needs a charging pile to charge, but there was no fixed parking space in my old community at that time, so I had to choose a public charging pile to charge.

However, there is another problem. Tang DM can only charge slowly. It takes about 6 hours from power shortage to full charge. The public charging pile is 2.6 kilometers away from my home. It is obviously unrealistic for me to wait for full charge in the car, but I can only choose to take a taxi if I go home.

It costs 23 yuan to take a taxi back and forth every time, but Tang DM only needs 21 yuan when it is fully charged. Obviously, this is very uneconomical. Originally, I bought a hybrid car to save money. As a result, the plug-in hybrid car relied on charging piles and charging slowly, which increased my living cost and time cost. I once regretted it very much.

Therefore, if you can’t install charging piles in your community, and there are no public charging piles within one kilometer around the community, then I don’t recommend you to buy plug-in hybrid cars, otherwise the charging problem will be the biggest trouble for using cars, and you will easily fall into regret.

Some time ago, my friend and I drove the Han EV to Tai ‘an, Shandong Province, with a total distance of 656 kilometers. My Han EV is a four-wheel drive high-performance version with a battery life of only 550km kilometers. I know that I definitely need to charge it once in the middle, and I have overcome the lack of coke oven feeling in my heart, but I am still hurt by the charging problem.

Han EV has the function of fast charging. It only takes 25 minutes to charge from 30% to 80%, and it can be fully charged in 40 minutes. What I want is to take a rest just by charging time, which is the best of both worlds, but it is actually completely different from what I thought.

I started from the new entrance of Wuhu City, and originally planned to charge in Jing ‘an parking area, which is 443 kilometers away. However, the pure tram ran at a high speed, and I turned on the air conditioner, and the power consumption was much faster than I expected. As a result, when I was 100 kilometers away from Jing ‘an parking area, the power was not enough for me to drive, so I had to choose to charge in Huangzangyu service area, which is 367 kilometers away from the new entrance.

When I drove to the Huangzangyu service area, not only were there cars charging, but there were also three cars waiting in line in front of me, which caused me to wait in line for an hour, plus it took 43 minutes to charge, which was nearly 2 hours from entering the service area to leaving a shared place.

I think that the anxiety of pure trams can be ignored since they have the fast charging function. Now the most unacceptable problem is the queuing problem of high-speed charging. Usually, there may be no need to queue up at high speed, but once they travel at the peak of holidays, pure trams may have to face the problem of charging queuing.

This problem can be slightly alleviated except for the new battery changing mode. At present, no effective way can be found. If the number of charging piles is simply increased, I don’t think it can keep up with the growth rate of electric vehicles.

Therefore, at present, pure trams still can’t solve the problem of running at high speed. If you need to run at high speed often, then pure trams are not the best choice for the time being, otherwise the problem of queuing at high speed is enough to make people collapse.

At present, many used car dealers are reluctant to accept pure trams and hybrid cars. In fact, this is not because used car dealers intend to suppress new energy vehicles, but because of their own problems.

The first question is, although the power battery has a lifetime warranty or an 8-year 120,000-kilometer warranty, there is no need to worry about battery failure, but battery attenuation is inevitable.

Because the power battery will decay, it is doomed to be unable to preserve its value in the used car market, and the depreciation rate is much higher than that of traditional fuel vehicles, so many green car owners will regret when selling used cars, and feel that green cars do not preserve their value.

The second problem is that new energy vehicles are developing rapidly, the technology iteration is too fast, and the battery life is increasing every year, resulting in no one willing to buy used cars.

Let’s take an example. The Tang DM I bought three years ago didn’t have the fast charging function, but now Xintang DM has it. Then the battery life of the pure tram three years ago was basically about 300 kilometers, and now the pure tram cruising is more than 500 kilometers.

This technical update and the increase of battery life have led to a very serious situation in the field of new energy vehicles, so users are unwilling to buy, and second-hand car dealers are naturally unwilling to accept, and new energy vehicles are doomed to be worthless.

Therefore, if you are particularly concerned about the hedge ratio and hope that new energy vehicles can sell at a good price in the future, then I advise you to think twice before buying a "green car", otherwise you will regret it because of the low hedge ratio in the future.

There are many advantages of pure trams, but what impressed me the most is not the strong power and cheap car use, but the huge space and ultra-low failure rate of pure trams.

Because the pure tram has no engine, gearbox and fuel tank, the space utilization ratio is much larger than that of the traditional car. The rear space of the Han EV is really excellent, even richer than the new space. It is not only more than enough for three people to ride in the back, but also very comfortable.

As far as I’m concerned, I have no regrets about buying two green cars. The quality experience brought by new energy vehicles can’t be given by fuel vehicles, so I feel very worthwhile.

Whether it’s a hybrid car or an extended-range electric car, the future of the green brand car is actually a pure tram. Although the pure tram has solved many pain points, it is still in the stage of rapid development, and there are many problems that need time to solve.

For the development of new energy vehicles, a large number of car owners are needed to support them now, but for the buyers, they have to face the harm to their own interests in the development of new energy vehicles.

Therefore, before buying a green brand car, you must combine your own actual situation and think twice before you act. Only in this way will you not regret it.

The Annual Album of the 51st Grammy Music Awards-"Raising Sand"

　　　　At 9: 00 a.m. on February 9th, Beijing time, the 51st American Grammy Awards Ceremony was held in stamps Center. Raising Sand Robert Plant & Alison Krauss won the Album Of The Year.

B.B.King pays tribute to the dead pioneer as if going back in time.

　　　　BuddyGuy, B.B.King, JohnMayer and KeithUrban joined hands to pay tribute to the dead rock and R&B pioneers. Their performances seemed to bring us back to that era when blues was prevalent. Especially the old B.B.King is still the familiar Gibson and the familiar smile.

Radiohead’s debut performance is grand, and the style is still decadent and different.

　　　　Radiohead appeared, and the performance lineup has never been grand. They continued their decadent and alternative The English Patient style, and this year’s best alternative music album was awarded to their 2008 album In Rainbows. Radiohead is not a high-yield band, and there is no reason to award the best alternative music album to others. According to their release speed, it is difficult to see them at the Grammy more than ten years later. This award is more like an encouragement, a symbolic encouragement. Who let Radiohead not be favored by the Grammy jury?

Paul McCartney has no bright spot. Nirvana, the old drummer, has the same momentum.

　　　　Paul McCartney’s special performance with Foo Fighters was not as infectious as the previous legend. There was almost no bright spot except the Beatles’ bass melody line that Paul could still find. Dave Grohl, the soul figure of Foo Fighters, returned to the position of drummer, only with the momentum of Nirvana dynasty.

Mariachi Divas won the best Mexican local music album.

　　　　Mariachi Divas won the Best Regional Mexican Album.

After M.I.A got pregnant, she still tried her best to announce that the due date is today.

　　　　Kanye West, T.I., Jay Z and M.I.A performed at the same time. M.I.A’s performance after pregnancy was still hard, and some people were surprised at the venue. Kathy Anderson, who went on stage to announce the next group of performers, declared that the expected date of delivery of M.I.A was today.

Robert Plant and Alison Krauss won the Best Production Award of the Year.

　　　　The best production award of the year was won by Robert Plant and Alison Krauss’s "Please Read The Letter". Coldplay’s "Viva La Vida" did not continue to write myths. Robert Plant said that the production process of this song was very easy and he did not forget to thank Jimmy Page, a former comrade-in-arms. Robert Plant has gained a lot in this Grammy, which also verifies what he said before. As a musician who is not young, he must make new music. There is no doubt that Robert Plant and Alison Krauss did it.

British singer Adele won the Best Newcomer Award. Fat girl dreams Grammy.

　　　　The Best Newcomer Award was won by Adele, a British singer. She was obviously excited when she made a speech on the stage, thanking her mother in London and her good friend Duffy. It can be seen how much effort this fat young girl born in 1988 has made.

Katy Perry, red and green with costumes, funny dance, panting

　　　　Katy Perry, nominated for the best female voice in this Grammy, danced on the stage, and Katy Perry’s red and green costumes were still funny. At the end of the singing of I Kissed a Girl, Katy Perry’s physical strength was obviously exhausted and even her voice trembled. Panting fully shows that she should strengthen physical exercise.

Coldplay won the best rock album again.

　　　　Coldplay won the award again, and the best rock album was won by them. Viva La Vida resounded through the award ceremony for the third time. Blink182 was the guest of honor, and the drummer Travis Barker wore a plaster. The appearance of three members suggested that Blink 182 really came back.

Jonas Brothers took the stage to perform the guitarist "Orchid Finger", which surprised the audience.

　　　　Jonas Brothers and Stevie Wonder collaborated on the stage, and Jonas Brothers guitarist’s "Orchid Finger" appeared many times in the performance, which made the fans look amazing.

Jennifer Hudson took the stage to sing the true feelings and moved the audience.

　　　　Jennifer Hudson, who won three nominations, sang on stage, and her emotional singing moved all the audience present. At the end of the performance, Jennifer Hudson almost shed tears with excitement.

Taylor Swift collaborates with Miley Cyrus, and beautiful women shine on the stage.

　　　　Taylor Swift cooperated with Miley Cyrus, and four male performers on the circular stage became the real foil for these two beautiful singers.

Kid Rock went on stage to sing, and his costume changed, just like Bob Dylan.

　　　　Kid Rock, an American rock singer, brought several duet songs to the stage. It is worth mentioning that Kid Rock changed his old style of wearing sunglasses, a black suit and a black hat. At first glance, he looked like Bob Dylan, and Kid Rock Kid Rock was nominated for the best pop male voice in this Grammy.

Coldplay was accused of plagiarizing songs and won the grand prize.

　　　　Coldplay band Viva La Vida won the song of the year. Four members of the band wore blue, green, red and purple tops respectively, which made the band radiant, and Coldplay came prepared. The familiar melody of viva la vida sounded for the second time at the award ceremony. The drummer’s acceptance speech thanked his family and fans, and the rumors of the band’s dissolution completely vanished. It seems that Coldplay will not care about plagiarism rumors, and even the American jury agrees with Coldplay. I believe that American guitarist Joe Satriani will still be ruthless?

Sugarland won the grand prize, which means it’s an honor to be on the same stage with Coldplay.

　　　　In the acceptance speech, Sugarland, the best country group singing award, thanked her parents and said that she was lucky to have the opportunity to be on the same stage with Coldplay. Is this ironic British rock or real appreciation?

　　Since the establishment of the German Artificial Intelligence Research Center (DFKI) in 1988, the German government has been funding artificial intelligence research. Image source: German government website

　　The world tide of scientific and technological innovation ⑦

　　Our reporter Li Shan

　　Artificial intelligence (AI) is a core technology in the future and one of the important driving forces of digital transformation. German AI has strong basic research strength and international competitiveness in self-driving cars, but it has lagged behind the countries leading the market in many other application fields. To this end, Germany has taken many measures to catch up, hoping to become a leading place for the development and application of AI technology and embark on a road of AI development different from that of China and the United States.

　　Increase investment and provide a good environment

　　In terms of research and development funding for AI, the German government plans to invest 3 billion euros by 2025 to ensure competitiveness on the basis of good research and innovation policies. This guiding role is obvious, and local governments have increased their investment. For example, Lower Saxony decided to invest 17 million euros to expand and develop the branches of the German Artificial Intelligence Research Center (DFKI) in the next five years. In addition, Bosch also announced that it will invest 4 billion euros to develop AI technology by 2021, thus making Bosch an indispensable partner in the field of autonomous driving.

　　In terms of talent competition, Germany plans to increase at least 100 professorships in the AI field and establish an ambitious young talent program. However, the situation of AI brain drain in Germany is not optimistic. The salaries provided by countries such as China and the United States for AI experts often reach two to three times that of Germany, plus considerable research funding. In the future, Germany will still face the challenge of shortage of relevant talents.

　　In terms of strengthening the construction of scientific research centers, Germany focuses on continuing to develop and expand DFKI, especially the four centers in Berlin, Munich, Dortmund and Tü bingen. At this year’s Hannover Messe, DFKI showed its own AI research achievements in the public expectation, including version 4.0 of Human-Machine Collaboration (MRK4.0), interpretable AI system, digitalization and Internet of Things in the construction industry, wearable health equipment for the workplace, autonomous robots in space, adaptive interactive teaching and learning systems, and so on. In the next step, Germany will gradually establish a national innovation network consisting of 12 artificial intelligence research centers on the basis of DFKI talents.

　　Integrating into European Strategy and Developing International Cooperation

　　Germany is fully aware that a successful AI development strategy needs to cross national boundaries, and it cannot keep pace with the ambitious development plans of enterprises and research institutions in the United States and China on its own. Therefore, Germany organically combines its AI strategy with that of Europe, strengthens coordination and gives full play to the advantages of international cooperation and division of labor. With the strong support of Germany, CERTLAB has grown rapidly since it was launched in the summer of 2018. It has been supported by more than 2,800 European scientists and has built a strong network.

　　The second is to strengthen German-French cooperation. In January 2019, Germany and France signed the Aachen Treaty, and the two sides will carry out extensive research and innovation cooperation, including establishing a German-French artificial intelligence research and innovation network, formulating ethical standards for new technologies in the field of digitalization and digital society, and reaching common values at the international level. The German Federal Ministry of Education and Research (BMBF) regards the R&D and application of AI as a priority area for future scientific and technological cooperation between Germany and France, and hopes to jointly set up AI research projects, institutional interconnection and jointly create a new framework for AI technology transformation with France.

　　Once again, it is closely cooperating with Japanese AI research, especially in the field of autonomous driving. In February this year, German Chancellor Angela Merkel visited Japan and reached a consensus with Japanese Prime Minister Shinzo Abe on strengthening cooperation in digitalization and AI between Germany and Japan. On April 16th, Germany and Japan signed a letter of intent to strengthen research cooperation in the field of AI. The German Research Foundation (DFG), the French Research Center (ANR) and the Japan Science and Technology Promotion Agency (JST) jointly funded transnational cooperative research in the AI field, and the first batch of projects will be launched this summer. Germany will also open more AI competence centers to Japan. In the future, Japanese visiting researchers can conduct research in Germany within a certain period of time.

　　Finally, through international cooperation, Germany hopes to solve its own data source problem. At present, Germany does not have a competitive data platform in the world, and the data information available for AI is scattered among many enterprises. The market model determines that it is difficult for Germany to integrate a large amount of data in the future. On the one hand, Germany needs to solve the problem of data dispersion, break down the "data barrier" and increase the research and development of distributed AI; On the other hand, we have to hope for international cooperation, strengthen data exchange and sharing for machine learning, and provide a massive information foundation for our own development of AI.

　　Find another way to enhance their competitiveness.

　　Germany attaches great importance to cultivating the lighthouse effect of AI, actively carries out research in humanities and social sciences, so as to enhance the social influence of AI as soon as possible, emphasizes the necessity of supervision, and conducts social discussions related to AI. With the participation of German experts, on April 8, 2019, the European Commission issued the core requirements for trustworthy AI, hoping that this new ethical norm can enhance people’s trust in the AI industry.

　　Germany starts from the field of testing and certification that it has absolute advantages, and actively promoting trust is the premise for people to widely use AI products. DFKI first launched a joint project with the German testing and certification agency Sü ddeutsche Zeitung to certify the AI system for self-driving cars; Then a new certification and digital sovereignty laboratory was established, focusing on the controllability, interpretability, stability, security and fairness of AI. On April 19th, the German Federal Minister of Education and Research Kalicek further proposed that we should consider setting up a testing certification for the "Made in Europe" credible AI. She thought that such a label was a good selling point even in Europe.

　　In addition, Germany also attaches great importance to promoting the understanding of AI from all walks of life by popular science and improving the social identity of this new technology. The German Federal Ministry of Education and Research has chosen AI as the theme of the 2019 Science Year, hoping that society, science, economy and politics will have more extensive exchanges on AI. The organizers of the Science Year will explore the working principle of AI in various forms, such as movies, seminars and public participation, shape the future mode of man-machine cooperation, and discuss the ethical issues brought by AI technology and its impact on social life.
