　　Cctv newsThe 2022 Winter Olympic Games will be held in China, and the China government has once again made a promise of "Green Olympics". Around this goal, it is an important link to realize green transportation during the Olympic Games. On August 31st, Beijing Institute of Technology and other research teams released an achievement: the all-weather battery product was successfully developed, that is, the battery of electric vehicles can still work normally under all climatic conditions, including extreme low temperature.

　　In the cold environment, electric vehicles will face challenges.

　　After investigation, during the Beijing Winter Olympics, vehicles will face a low temperature of -20℃ to -30℃, and the use of new energy vehicles will face the following challenges ↓ ↓

　　The charging and discharging characteristics of the power battery become worse!

　　Battery capacity and life will also decay!

　　These will lead to a significant decline in vehicle driving range and vehicle dynamic performance!

　　Sun Fengchun, Director of the National Engineering Laboratory of Electric Vehicles of Beijing Institute of Technology and Chief Expert of the Expert Group of Beijing New Energy Vehicle Association:

　　Now the electric vehicle (cruising range) has reached more than 300 kilometers, but it may only run for dozens of kilometers at MINUS 10℃.The farthest distance between the two venues of Beijing Winter Olympics, that is, the Chongli distance from Wukesong in Beijing to Zhangjiakou is 260 kilometers. How to last the electric vehicle at low temperature is a problem that must be solved.

　　New technology, let electric vehicles break through the low temperature forbidden zone

　　The team led by Professor Sun Fengchun developed the world’s first all-climate battery product by using the rapid thermal conductivity generated by metal heating inside the battery. The key technologies are as follows ↓ ↓

　　A layer of nickel-platinum sheet was added to the existing lithium battery.

　　Connect the power supply, and the battery can be heated quickly!

　　Sun Fengchun:

　　At MINUS 30℃, the temperature of our battery rises to above zero in twenty seconds, so it can work very well and has no influence on the life of the battery. This is the core technology. In other words, there is no forbidden area for electric vehicles, which is a milestone principle and technology in this respect.

　　Low temperature environment, all the key technologies of new energy vehicles are overcome.

　　In addition, key technologies such as vehicle system integration and control in low temperature environment have also made breakthroughs. The cooperative control technology of automatic driving and automatic charging has laid a solid foundation for the application of new energy vehicles during the Winter Olympics.

　　Sun Fengchun:

　　From the battery cell, battery system to the system integration of the whole vehicle, it should be said that the technology has been completely overcome.Our core key components are required according to the standard of low temperature of MINUS 45℃ to ensure that there will be no problems during the Winter Olympics.

　　At the end of this year, all-weather electric vehicles will be launched.

　　According to reports, the first batch of all-weather electric vehicles in the world will be released at the end of December this year, and then they will go to Mohe and other alpine regions for experiments at around MINUS 45 C. It is estimated that in 2020, the development of 11 product prototypes of four types of vehicles will be completed, and the demonstration operation will begin.

　　Zhang Jihong, Deputy Director of Beijing Municipal Science and Technology Commission:

　　We should further integrate some technologies from Beijing, China and even foreign countries to tackle key problems in Industry-University-Research. Whether it is low-temperature battery technology or driverless technology, a complete and comprehensive presentation can be obtained during the 2022 Winter Olympics.

Live on November 3 rd, in the second stage of the Olympic preliminaries, the Korean women’s football team advanced to the top of Group B, while the Chinese and Korean women’s football teams were out of the group. As for the reasons for the gap between the strength of Korean women’s football team and that of China’s women’s football team, as well as the candidates for the women’s football coach position in China in the future, Football Daily published an analysis and gave some suggestions.

The living environment of Korean women’s football team is not clear to the outside world, but we know that there are no players studying abroad, and they all play in local leagues. One question is, is the level of Korean leagues higher than that of women? If so, doesn’t that mean that the league we have worked so hard to build is just a show?

But that’s the answer. Although the women’s super clubs didn’t get the bonus of "Jinyuan Football" in those years, most of them can survive now with government background. Moreover, because they undertake the task of the National Games, they are still valued to some extent, at least they won’t be easily abandoned. But the cruel fact is that the training level of the clubs, including women’s super clubs, is really not good, or even worse than that of the sports teams in those years.

The root cause is closely related to the level of coaches. An insider said: China’s local coaches prefer the men’s Super League, China A, China B and the echelon, and only when there is no place to go will they choose the women’s football team. Their level is not high, and even the coaches in the women’s football team are even lower. Even so, these coaches are highly mobile and can’t stay. So, will the players taught by this kind of coach have a future? Or "usable"?

At present, there are several options for the future women’s football coach. One is to keep water to celebrate the summer; The second is to hire foreign coaches; The third is to choose local male coaches.

The three choices have their own reasons and disadvantages, but what the China Football Association should remember is that the women’s football team has been tossing and turning, and foreign coaches have invited it. The men have Bruno and Eyjolfsson, and the women have domanski and Elizabeth. The only successful one is Bruno. Unfortunately, because of the poor record in the warm-up match, the China Football Association and others dismissed it, resulting in FIFA; Local men’s coaches have also been used, such as Zhang Haitao and Pei Encai in the early days, Li Xiaopeng and Hao Wei later, and Jia Xiuquan recently. It is true that Ma Yuanan and Ma Liangxing have found the right pulse and are close to success, but what they do now may not be suitable.

Therefore, the future China women’s football team, the coach must "fit" or "adapt", but what kind of fit? This requires Song Kai and representatives from all aspects of the women’s football community to conduct in-depth research and communication, and listen to opinions widely. If Shuiqingxia does not stay, Japanese coach is actually a good choice.

As a naturalized player in Chinese football, Garatt has dismissed the contract with the Guangzhou team and returned to his hometown of Brazil to find a new playing opportunity. There is no exact news about whether Gaunt will retain Chinese nationality in the future. However, for the return of the former Brazilian international, many Brazilian fans have unexpectedly "interest".

Earlier, it was reported that Gaunt attracted the attention of the Brazilian Furniture, including Barona, Flaglo, and Palmeras. But in the Corinthian forum, most fans oppose the team’s introduction of Gaunt.

Some fans said: "Gaurat used to be a good player before, but now his knee cartilage has been removed. It is difficult for this player to play high -level football in the future. When I left, Parmeras was like a pig who hit the Universiade because they got rid of this high salary burden. "

There are also fans believe that since Gaunt has joined Chinese, it seems a bit awkward to play in Barn: "He used to be absent for more than five months due to injuries. And he has joined the Chinese nationality. He is equivalent to wasting a place for foreign aid. "" I don’t know what he is now. I mean, don’t he already have a Chinese state? In Brazil, he is a foreign aid, so what does it mean to come back? "

In addition to doubts about the problem of Gaurart’s nationality, more fans are not optimistic about Gaunt’s competitive status today. "Even from an optimistic perspective, Gaunt is mostly similar to the current Dordinho, and it will even be even worse. When he returned from China, his performance had begun to decline. And say. "" God bless you not sign Gaunt, he can no longer play in Brazil. Now he is no longer three years ago. "
