Mobile charging car, emergency charging cabin … Accurate and scientific layout to alleviate the "charging tide"

  CCTV News:In the past few days, many places in the country have ushered in the peak of returning home. According to the data of the smart car networking platform of the State Grid, as of February 5, the charging amount of new energy vehicles in the expressway service area on the platform has increased by more than 60% compared with the same period of last year. With more and more new energy vehicles joining the returning army, the "travel tide" has formed, and the "charging tide" of new energy vehicles has also appeared.

  The data shows that in the 11 days from January 26th in Spring Festival travel rush to February 5th, the charging amount of new energy vehicles in the expressway service area reached 34,089,100 kWh, and the charging times reached 1,519,400, which were 67.06% and 48.42% higher than that in Spring Festival travel rush in 2023, respectively.

  According to the platform data, during the Spring Festival travel rush in 2024, the peak period of the whole high-speed busy index reached 30%— 40%, which shows that among all the stations on the expressway, there are 30%— 40% of the stations are fully charged. At ordinary times, the charging busy degree of these stations is only about 10%, and the busy degree has doubled or tripled, showing an obvious tidal phenomenon.

  Emergency charging compartment of mobile charging vehicle should deal with "charging tide"

  In view of the "charging tide" brought by the "travel tide" of new energy vehicles, during the period of Spring Festival travel rush, many places in China took various measures to solve this problem.

  It is predicted that during the Spring Festival in 2024, the average daily charging capacity of Jiangsu expressway service area will reach 600,000 kWh, a year-on-year increase of 70%, a record high. In order to alleviate the charging pressure, Taizhou power supply department has reformed 7 service areas and 14 charging stations within its jurisdiction, and equipped mobile charging vehicles. In Qinhu service area on Yanjing Expressway, a 120kW mobile charging vehicle is specially equipped, which can provide uninterrupted charging service for four electric vehicles at the same time.

  In Pingwang Service Area, Wujiang District, Suzhou City, there are 16 charging parking spaces in the north-south direction. Since Spring Festival travel rush, affected by high-speed tidal phenomenon, eight charging parking spaces on the north side of the service area are basically full every day, but there are vacant parking spaces on the south side. Local staff guided some cars on the side with large traffic flow to the opposite idle service area for charging through the two-way culvert, which effectively improved the bearing capacity of the service area.

  In Tianjin, in order to reduce the waiting time for new energy vehicle owners to charge on expressways, the local electric power department started the emergency charging cabin in the expressway service area on the one hand, and upgraded the charging facilities of 46 busy high-speed charging stations in advance. After the renovation, the average charging time was shortened by nearly 30%.

  Scientific layout to ease the expressway "Charging tide"phenomenon

  China has been speeding up the layout of charging piles, so that electric vehicles can alleviate the "energy-filling anxiety" of expressways. In the future, this phenomenon of "charging tide" is expected to be alleviated with the increasingly intelligent and efficient energy-replenishing network of expressways being gradually woven.

  According to the data of the Ministry of Transport, at present, there are more than 20,000 charging piles in expressway service areas nationwide, covering nearly 50,000 parking spaces for minibuses. The coverage rate of charging facilities in expressway service areas in Beijing, Liaoning, Jilin, Shanghai, Zhejiang, Hunan and Xinjiang has reached 100%.

  According to the data of China Electric Vehicle Charging Infrastructure Promotion Alliance, at present, the increment ratio of piles to vehicles is 1:2.5, and the construction of charging infrastructure can basically meet the rapid development of new energy vehicles. Experts say that highway charging piles are usually idle and not enough for holidays. To solve this "tidal" problem, we should not just consider the increment, but also improve the quality to ensure its economy.

  In Liaoning, for new energy vehicle users, the local high-speed charging travel guide has been issued, so that drivers can check the layout of charging piles in advance, so as to better plan the charging line. At the same time, the local power department also accurately grasps the status of each charging pile, such as pile body, display and charging cable, through the digital platform, and problems can be solved in real time.

June net text book list | Daily dog food, fierce medicine to save the book shortage

[Editor’s note]Through the superficial phenomenon of "little white" in online literature, many works with equal emphasis on entertainment and ideology have been born. This book list will introduce a more diverse online world, from the unpopular to the popular, from the small crowd to the public, and those outstanding works of various types.

Uneasy Daily Lazy Angel

Comprehensive daily city youth

The story tells the story of the protagonist of the fun man, as a social terrorist, who engages in daily activities in the world of spring things. The story line is mainly about spring things, including bunnies and ice cakes, and there are some super-power elements (not many), which are unique in the development of the original work. Through the protagonist’s epileptic behavior, he psychologically persecutes all the cartoon characters and promotes the emotional progress of the characters.

The protagonist’s personal design should be the biggest highlight of the novel. The whole process is full of joy, self-release, willingness to spoof, epilepsy but not infatuation, and constant coquettish operation. It is like a social terrorist to solve the problems and contradictions between the original characters and solve others. It can be called a blow to reduce the dimension.

The controversy lies in: the background setting of the same person and the integration of a large number of secondary elements in the writing set a high reading threshold to some extent. If you don’t have a certain understanding of the secondary elements, it seems that you will still be confused.

The recommendation index, from three stars to five stars, is recommended to book lovers who like fun, have requirements for writing, like daily plots and don’t dislike two-dimensional light novels. From the feedback point of view, two-dimensional readers must see it, and non-two-dimensional readers are also worth a try. There are many fragrant parties. After all, there is no lack of such feedback: "Even people who don’t know who the original male owner of Spring Things is can enjoy it with relish", and it’s really the whole journey if they can get the radio waves.

"The King" New Sea Moon 1

Low Magic and Western Fantasy, Lord Farming, Ancient Morning Wind and Bai Shuangwen

The background is the sword and magic version of the coexistence of all ethnic groups in the Middle Ages. The protagonist dressed as the second son of a noble, obtained the qualification of counterinsurgency with excellent negotiation skills and social skills, became a baron of fiefs in the war, embarked on the road of land reclamation for hegemony by the lords, struck a balance among the nobles, exerted great tricks, constantly made achievements, and integrated many elements, writing the feeling of gradual upgrading and step by step.

The setting and the plot are as ancient as the wind, and the words are humorous and not bitter. The author has his own understanding of the interests of western nobles. The description of the background of medieval rules and the struggle of aristocratic tactics (intrigue) with sophisticated human feelings are the highlights. The descriptions among the nobles are relatively real, and the leading and supporting actors have their own set of behavioral logic, which truly describes the shameless and brutal of the nobles. The feeling is the infighting, lords disputes and kings in the Middle Ages.

The problem is that the style of writing is dry, the words are not fastidious or fantastic, the description of characters is big and empty, the description of war is broken down, the setting of fantasy part is very old-fashioned (dreaming back twenty years ago, you dare to believe in quarrelling), the stitching is also very general, neither fish nor fowl, the space of tactics part is more, a lot of space is used to play Tai Chi with politicians, and the tension of plot is mostly described by the language of characters, which is monotonous and mediocre, some take it for granted, lacking rationality and reality.

Recommended index, 2.5 stars to 4.5 stars, should not expect too much, no poison is not recommended to read. Finally, I want to emphasize this sentence. The controversial book with constant heat must be worth a try.

"Firepower is king" is like water.

In recent years, the rare high-level urban mercenary military literature monthly good review book

Gao Guang, the protagonist, is a military fan who practiced martial arts since childhood, majoring in foreign languages at the university. He was kidnapped by drug dealers when traveling to Mexico. In order to survive, he fought against his opponent, cooperated with mercenaries who happened to rescue hostages, started to get in touch with all kinds of firearms, and set foot on the journey of legal mercenaries (private military contractors) based in beautiful countries. From then on, he began to experience the flames of war, sell information, participate in wars and devote himself to providing war-related peripheral services.

The language is simple, the leading role and supporting role are flesh and blood, the team plot is very happy, the task plot is tense and exciting, and it is clean and vivid. The description of the battlefield is incisive and interspersed with well-informed military knowledge and popular science. Compared with the previous plot that focuses on fighting, there are many more political and conspiracy developments, and the writing style has been greatly improved.

It should be noted that there is little difference between the protagonist template and the previous work. From the previous work, the daily plot is a sub-item, and the emotional drama is also a sub-item. However, if you look at the military literature, these issues are not the focus.

Recommended index, three to four stars. Many book lovers think that this is the author’s work to return to the peak, and the theme is rare. It is suitable for book lovers who are tired of watching Xianxia fantasy and Dihua simulator, for a change and to find feelings.

Henghua is bright and bright.

Family immortal writing

The protagonist is dressed as a member of the family of cultivating immortals, just as the family’s bodhi old zu has not yet broken through, with only ten years left. The surrounding forces are eyeing up and the family is tottering. Fortunately, the protagonist is born with wisdom and amazing understanding, and is good at deducing the family’s achievement methods, so he becomes the family’s acting master, responsible for deducing the family’s achievement methods, helping people tailor-made personalized achievement methods suitable for personal physique, and assisting his grandfather to create suitable Yuan Ying achievement methods, which is similar to that of coaches to athletes.

The style is fresh and the setting is interesting. The protagonist has a partial counselor’s wits, and the Golden Finger is a step-by-step self-created achievement method based on the cultivation formula in the last The Journey to the West. The family atmosphere belongs to unity and friendship, and the writing style and world outlook are somewhat similar to tahoe’s Ming Zun. The theoretical system is relatively complete, and it is not a kind of underworld cultivation. At the end of the chapter, the author will summarize the plot content of this paragraph by means of history books, which is well received.

Controversy lies in the fact that the plot is well-behaved, everyday dull, multi-line, messy and sloppy, the writing ink, the description of the fight is dry, the overall cool point is insufficient, and the plot is particularly jumping. One second it is still saying A, and the next second it is already saying D, and it is easy to lose key information with ten lines.

Recommended index, three to four stars. If you like tahoe, it is worth a try. For me, the biggest attraction is the fresh style, interesting settings and all kinds of strange spells, which makes my setting party very satisfied.

"The Rise of House" Hushan Small Farmers

Fairy Tales, Urban Fantasy, Leisure, Wind and Buddhism, Farming Literature

I don’t know if there are any old book lovers who remember this 16-year-old house masterpiece. The whole plot idea is very different, which can be said to be incompatible with the mainstream online text upgraded to the core. The protagonist is bent on staying at home as a salted fish, with no dreams and no goals, which is very consistent with the current feeling of lying flat. It took a little fire for a while, but it passed like a meteor, and the subsequent works have no such influence.

The hero of the otaku who returned to his hometown woke up to the power of seeing the second dimension, and was able to transform the comic books and movies in the second dimension into the third dimension. So he planted a lovely Macey person, brushed tasks, collected materials, and built an animation comic game studio necessary for otaku. From time to time, he went out to take a risk with the villain of the second dimension, steadily developed farming, developed his own second dimension village, and gradually became the king in his own small world, with a sense of little luck.

Generally speaking, it is a kind of house-writing with no house smell, which is leisurely and interesting, not monotonous, unique in style, and the cool point of the protagonist is different from that of the public. The kind of one who enjoys himself does not pursue the sage before others, sticks to his own local world, and pays attention to his own happiness is the most important.

It should be noted that the whole is not cool in the usual sense, but rather self-satisfied in the later period, and there is not much cool point in business, or it is not refreshing enough. There is no in-depth development of business lines related to games and animation in the works.

Recommended index, three stars to four stars, book lovers who want to see the upgraded works had better be cautious.

Frank, the handsome dog in Dawn Trail of Beautiful World

Meiman infinite flow

With the proficiency system, the protagonist crossed the beautiful world and dressed as a minion of the DC Gotham villain organization. He wanted to jump ship to Batman but mistakenly entered the evil organization (Stars Club), and was forced to pick up garbage in the HP world where the doomsday collapsed. Fortunately, knowing the relationship between the characters, the captain died, and successfully got rid of the control of the cat hunters by using the ability of the golden finger. Later, in order to stop the doomsday, he led the team to shuttle through the world, recruiting and constantly backstab.

The novel is a multi-universe worldview based on beauty, with infinite flow elements, the copy is mainly in the western fantasy world, mixed with behind-the-scenes story puzzles. The main world is Batman, the protagonist is neutral in order, kind to decency and evil to villains. The author has his own understanding of big events, and does not copy comic books. The interaction of each world has its own characteristics, the main line is clear and not procrastinating, and the small subplots are also touching, so the deduction is reasonable.

It should be noted that as a beautiful fan, it is not qualified. Basically, the popular characters are background boards. There is no sense of surprise in writing a large section about the struggle between the protagonist and the original villain. The update is fast, which leads to a rough plot (insufficient details), many loopholes, and a mix of multi-world systems. The level is slightly chaotic, and there are disputes with some female characters’ ambiguous plots, but the conclusion is still decisive and the landing is relatively smooth.

The recommendation index is three stars. On the whole, it has outstanding advantages and disadvantages, and it is worth a try. In the words of book lovers, "The audience and the previous wow should be highly consistent, the game is beautiful, there will be no obstacles to understanding, and the setting is old, but it is very capable."

"Unemployment at the beginning, I let the singer return" Cheng Yanqiu

Entertainment circle daily copy class

When the mood swings violently, there will be corresponding music works played on the earth, but only the female host can hear it. The female host, who was originally a minority singer, became attached to the male host on campus because of her songs, so she took the initiative to chase after her brother and sister, and finally came together. Because of these songs from the earth, she became a legend in the music world.

From the perspective of novel career line, it is a literary copying type. First, the female protagonist becomes a legend in the field of music. While the male protagonist gives her assistance, she copies novels, plans, advertisements, plays and other multi-line developments, while the female protagonist provides financial support for the male protagonist’s career. The whole description is warm and smooth, and there is no particularly fierce conflict. Both the development of love and friendship are written naturally and healthily.

It should be noted that: "the female host feels a little far-fetched in explaining the origin of the work to the male host, and tells the male host that it is a song sung by the male host when he is asleep;" Secondly, the male owner’s career line has a large span, many threads, and the overall idealization, which makes it look very fragmented and relatively scattered. Many plots appear to be mentally retarded. Of course, it doesn’t matter if you come to the dog food. By the way, the man was only a freshman when he first wore it, and he passed through the woman who met five years later, so he was naive and mature. "

Recommended index, 3.5 stars to 4.5 stars. Sincere and plain, very harmonious, there is an indescribable sweetness, which is suitable for reading when you want to relax. Children’s shoes like "This star comes from the earth" and "The actor has no holiday" can be tried.

Lost moral integrity in Abnormal Ji

Wuxia Kesulu

The new book "Portrait of the Mask" and "Beyond the Burning Burnt" by the author is an old author in the late stage of Wenqing Cancer. The style is unique, and the whole protagonist is neurotic and brainwave. It can be said that they are all crazy people, and they love to let go of themselves. It may be that the sentence "Extraordinary people do extraordinary things" should be answered. The plot trend never avoids the minefield of online writing, such as the death of the hostess and seeing her off.

This time, it can be regarded as a martial arts fantasy version of "Portrait of the Mask", which continues the world outlook of maggots and flies, ghosts and immortals, and degenerate songs. The protagonist is a perverted martial artist, and because he is in a state of immortality at a price, he needs to forget martial arts to maintain immortality. In order to obtain martial arts, he is all kinds of grovelling, talking with rainbow farts, full of flattery, and playing the clown. As the saying goes,

It should be noted that after marriage, the author has converged a lot, with less crazy content, less hair knives, less toxic points, and no change of mistress in the middle. He poured water into the plot crazily, so that he can read it. In the words of book lovers, "The highlight of his book has always been the protagonist’s dressing up as a pig to eat a tiger, but there is no feeling of pretending at all. On the contrary, there is a little meaning that others laugh at me for being too crazy and I can’t wear it."

Recommended index, two stars to 4.5 stars. If you have a serious book shortage and are tired of reading online routines, you need strong medicine to save the book shortage cancer. You can also try to fight poison with poison and cure cancer with cancer.

Far pupil of Deep Sea embers

Mysterious Epic Works of 2022

Similar to the water world after the end of the dark sea, the world is destroyed and the old days are gone. The remaining human beings live on scattered islands and communicate by ships. The protagonist of a middle school teacher wakes up one night dressed as a ghost captain, and inherits a small part of his original memory. His body is similar to an evil spirit. He can take risks by randomly attaching himself to human beings through consciousness projection and explore the truth of this strange world.

The style of writing is relaxed and humorous, interspersed with various interesting stalks, the style of painting is quite smooth, the story unfolds and the bedding is set, with a secret sense of coolness, the world outlook is as grand as ever and full of suspense, the elements are complete, the dull sea, Cthulhu and so on are basically a little bit, and the techniques of Dihua flow are integrated. Through the protagonist’s exploration experience, the world structure, from the ocean to the polis, from reality to the spiritual world, is slowly unveiled like a curtain, with a sense of suspense.

The overall background setting is rich, the plot is compact, and the adventure wind is quite strong. Although it is of a patriarchal style, it does not suppress the gloom. The author uses humorous writing style to hedge the cruel reality of the world in the book. There is not much innovation in characterization, but it still gives strength. The combination of frighteners captain and garbage-talking Gothic doll miss and noisy tool, Mountain Sheep Head, looks interesting. In the words of book lovers: "This is a boundless sea adventure full of love and courage, warmth and laughter."

It should be noted that the controversial points come down in one continuous line with the previous works, and the homogenization of characters and the animation of words and deeds are the biggest persuasion points for readers who don’t like the second-generation style. If it is changed to pure western fantasy, it will be more pleasing to the Chinese, the old and the white. Secondly, the plot is slow and hot. Although the opening has consciously accelerated the pace, the story is still slightly slow and hot, giving people a feeling of water and needing some patience.

Recommended index, four to five stars. It can be said that the progress of Yuantong is very obvious, and all levels are surpassing the previous work. However, this book is even more tiring, and it is suitable for saving dozens of chapters to read together. If you read it once a month, you can borrow the words of book lovers: "The painting style of Cthulhu and Xiling has completed a historic meeting."

Industry 4.0: Three Directions of Digital Supply Chain

  Focus on cutting-edge scientific and technological innovation and upgrading of traditional industries

  The Industrial 4.0 Revolution sweeping the world has affected almost every industry, including the supply chain management of all industries.

  In the past, supply chain management was a headache for all industries, because the traditional supply chain involved a lot of fuzzy and inaccessible data, which swallowed up cost, time and patience like a "black hole". Industry 4.0 will give birth to a new digital supply chain and realize more complex and streamlined supply chain management.

  Digital supply chain is an important direction of industrial solutions and business processes in the future, including not only logistics, warehousing, transportation, but also engineering, research and development, manufacturing and asset management.

  With the application of many innovative technologies such as artificial intelligence, Internet of Things and blockchain in the supply chain, the traditional supply chain management is rapidly moving towards digitalization, intelligence and controllability.

  1. Cross-platform asset tracking that connects everything

  At present, GPS positioning is a mature technology with low price and low management cost, which is widely used in various fields. Through sensors connected to various assets or vehicles, the location and general time planning of assets can be obtained.

  Enterprises can track assets through bar codes and tracking numbers, and know where products and goods are being shipped. However, this kind of tracking and monitoring is far from accurate, and it will still bring many problems and inconveniences.

  For example, after shopping on the e-commerce platform, the logistics information shows that "the courier is delivering the goods", but we can’t know whether the courier will deliver it within the next hour or within three hours.

  In the industrial field, this inaccurate or delayed logistics distribution will bring some confusion to the production of enterprises, and even cause the production line to stop. Especially for manufacturers who pursue zero inventory, zero inventory not only refers to the timely delivery of final products, but also includes the inventory management of raw materials and equipment needed for production.

  Therefore, more accurate asset tracking technology will be an important direction of digital supply chain in the future. Hans Thalbauer, senior vice president of SAP, said, "We should not only create connections for goods, but also create connections for business partners. We need to connect not only suppliers, but also suppliers of suppliers. "

  The future digital supply chain should not only connect all links in the supply chain, but also connect all factors that affect logistics distribution, such as weather, natural disasters, road infrastructure, regional economy and even political influence, so as to minimize risks.

  For example, last year’s hurricane, which caused great damage to the American economy, affected the distribution of some suppliers’ goods, causing some automakers to shut down production. If we can get the news from the supply chain that "my supplier’s factory in Japan is affected by the earthquake and will stop production in the next two weeks", manufacturers can purchase products from suppliers in other parts of the world in time.

  2. Timely production and forecast monitoring

  As early as several decades ago, Toyota Motor Corporation initiated the concept of just in time to alleviate the problem of lack of cash, land and large inventory. Through the accurate management system, the response time of suppliers is shortened and the investment in process inventory is reduced.

  But the basis of timely production is that all parts and raw materials must arrive on time. On the automobile assembly line, the shortage of any part will affect the normal production of the production line. If the distribution of parts is delayed, it may lead to product quality problems or even downtime; If the delivery is too early, the factory is not ready to receive it, which will increase the cost of inventory management.

  In order to meet the production needs of large manufacturers, OEM will have strict delivery response time to ensure that parts can arrive at suppliers on time. However, this will bring great production pressure to suppliers. On the one hand, suppliers have to invest a lot of money in expedited transportation, and at the same time, in order to avoid the penalty of downtime caused by delayed transportation, suppliers must also maintain a certain amount of spare parts inventory.

  Therefore, timely production can improve the production efficiency of OEM manufacturers, but it will lead to low efficiency of suppliers, thus increasing the cost of parts.

  This requires the future digital supply chain to have the machine learning ability of real-time prediction. Through digital connection, it can realize predictive quality management, predictive manufacturing and predictive maintenance, improve the efficiency of production and distribution, and reduce costs.

  3. Blockchain and traceability

  The advantages of security, trust, traceability and controllability make blockchain one of the most potential new technologies. By creating a safe and transparent ledger system, all relevant stakeholders in the supply chain, such as manufacturers, retailers, logistics service providers and regulatory agencies, are brought into the same management platform, making the whole management process credible and transparent.

  In recent years, many start-ups that use blockchain technology to reshape supply chain management have been born. At the same time, traditional logistics giants have also begun to explore the application path of blockchain.

  For example, the shipping giant Maersk cooperated with IBM to develop the TradeLens blockchain platform, aiming at improving logistics efficiency and simplifying the documentation of global container transportation. After testing, the handling capacity of shipping documents is reduced by 10 times, and the transportation time is reduced by 40% on average. At present, nearly 100 partners around the world have joined the platform.

  Through opening up, blockchain technology can effectively prevent price fraud, transportation delay and payment delay, eliminate middlemen and effectively reduce transaction costs.

  In the industrial field, although the blockchain is still in the experimental and exploratory stage, once it is deeply integrated with industrial production, it will play an important role in future industrial production and digital supply chain.

  In the future, all kinds of new technologies will allow us to look at every link of the whole supply chain more rationally from the digital point of view, and help us to continuously improve our production, analysis, maintenance and forecasting capabilities.

  As Hans Thalbauer, Senior Vice President of Supply Chain and Internet of Things of SAP Company said, "This is a digital mirror. It is the digital twin of products, the twin of assets and a mirror of the world. This allows us to start the dynamic adjustment process. We hope to create a digital mirror image of the real world in this environment. "

How to charge new energy vehicles scientifically, do you understand?


Nowadays, there are more and more new energy sources. For many concerned car owners, how to carry out car maintenance, especially battery maintenance, has become a hot topic. Broadly speaking, charging is divided into three categories.

First, slow charging: almost all household charging piles belong to this category, because considering the overall voltage distribution of the community, it is generally controlled below 10w (Tesla is slightly higher). This method has relatively slow charging speed and takes a long time to fully charge the battery, but it has high charging efficiency and less loss on battery life.

The second is fast charging: the charging speed is very fast, and it usually takes about half an hour to fully charge the battery. However, the fast charging method has a great loss on battery life and needs to be used with caution.

Third, intelligent charging: intelligent charging is a charging method that can be automatically adjusted according to the battery state, charging voltage and charging current. This charging method can avoid the problems of overcharge and overdischarge to the greatest extent and protect the life of the battery.

The practice of stopping charging when charging to 80%-90% or the remaining 20% is mainly aimed at battery maintenance. In this case, keeping the battery in the range of 20%-80% is beneficial to the health of the battery. Because in this range, the state of charge (SOC) of the battery fluctuates little, which can effectively avoid deep discharge and full charge storage, thus delaying the aging speed of the battery.

For some new battery management systems, charging to 100% and discharging can give full play to the performance of batteries. The function of this management system includes actively balancing the battery charge to ensure that the SOC of each battery cell is consistent. In this way, the overall performance of the battery can be better played. For example, some electric bicycles feel that their battery life drops after being placed for a period of time, but after being used for a period of time, they feel that their battery life is back, which is the same reason. In the final analysis, new energy trams are electrical appliances, and for electrical appliances, they still need to be maintained frequently.

The correct charging method depends on your usage scenario and the function of the battery management system. If you pay attention to the life of the battery, it is a better choice to control the battery charge at 20% to 80%. But if you pursue the performance of the battery, charging to 100% and discharging it are more suitable for you.

At the same time, it is also very important to ensure that the charging environment of electric vehicles is dry, well ventilated and free of sundries, and to avoid charging in high temperature environment. Try to use original chargers, and avoid using poor quality chargers or non-original chargers. Inferior chargers or non-original chargers may have safety problems, which may lead to battery explosion and spontaneous combustion.

It is helpful to maintain the battery by deep discharge on a regular basis. In addition, frequent disassembly and assembly of the battery may lead to improper use of the battery and shorten its service life.

Grammy Madonna milks her breasts and shows her hips, and then Sam runs with her, becoming the winner.

    1905 movie network news The 57th Grammy Awards Ceremony was held in Los Angeles on February 8th, US local time and February 9th, Beijing time.

Katy Perry, the fruit elder sister, did not exaggerate the fruit shape, but dyed her purple hair instead. kaya jones was unwilling to be lonely, and combed her red buns to steal the camera. Those who don’t have "milking and dyeing their hair" can only wear an oversized long skirt to steal the mirror, but accidentally stealing the mirror is unsuccessful. Just like Princes Harris, wearing a black gauze skirt is like a black crow.

    Apart from female stars, this year’s male stars are really not worth watching, but they are still worth watching for the audience in China. Lang Lang, the "Piano Prince", won glory for his country and is expected to perform at the Grammy Awards this year. Although the shape on the red carpet show is not as "stunning" as that of Zhang Jiebao, who has gone abroad before, people in this country are still very much looking forward to it.

Sam smith won four prizes and became a big winner "Fruit Sister" to accompany Grammy 7 times.

    The opening song of the award ceremony was performed by Australian rock group AC/DC, and "Rock or Bust" and the classic single "High way to Hell" were played live! If ginger is still old and spicy, the audience will bring a bright little red corner to help when playing, which will stir up the atmosphere at the scene. The first award was announced by Taylor Swift, and finally sam smith won it. He was the biggest winner in this Grammy. In addition, as we all know, "Mouldy Mould" is a superstar on the stage, but it becomes a small fan in a second under the stage. No matter who performs, it is very popular to swing with the music, and this time is no exception, and it is still awkward. Later, Farrell teamed up with Lang Lang to perform the hit single "Happy". After the performance, Lang Lang also communicated with Madonna and took a photo with Jay Z. In addition, Ariana Grande, a popular female singer, performed a new single Just A Little Bit of Your Heart, which was included in her second album My Everything last year. Katy Perry, the fruit sister who accompanied the Grammy for seven times, sang a lyrical new single "By the Grace of God". After reading it, she really wanted to say, "Ask the judges for an award".

    Grammy regulars Lady GaGa and old artist Tony Bennet performed the theme song Cheek to Cheek in the Top Hat by Fred Astaire, the king of jazz dance. "Ga Jie" was elegant and jazz this time, and it was retro and unplugged. Hosted by Miley and Spicy Chicken, Madonna "Tianhou" appeared on the stage, making her debut in the new album Rebelhart, featuring the first single Living For Love. Grandma Mai is now 57 years old, but her singing and dancing are still hot and sexy, and her voice is still so great! Rihanna performed their new single "Four Five Seconds" together with "Kanye" Kanye Omari West. It is worth mentioning that "Japanese woman" wore a men’s interpretation of the single. Although the pink dress was fresh on the red carpet, the performance revealed Rihanna’s nature, and the men’s clothing was still cool and cool. At the end of the day, Beyonce made a stunning finale, singing the classic gospel song "Take My Hand Precious Lord" and singing the soundtrack song "Glory" with other singers who attended the tribute.

    In this Grammy nomination, British newcomer sam smith and American diva Beyonce led the way with six nominations. Among them, sam smith, who just released her first solo album, swept all the nominations for four general awards. In the last six nominations, he won four awards, including single of the year, production of the year, new artist of the year and pop album of the year, and was the biggest winner of this year’s Grammy Awards. In addition, when this year’s nomination list was first exposed, it was surprising that Lady GaGa’s "Art Pop" only appeared in the nomination for the best traditional pop album, but after learning that she was nominated for only one award, Lady Gaga still shared her joy on twitter. Give her a compliment for her generosity. At least she didn’t angrily announce that she wouldn’t attend the awards ceremony because her album wasn’t nominated for the album, as justin timberlake did last year.

    Except for Lady GaGa, Fruit Sister was nominated for the Best Pop Album Award by Prism this year, but it was finally won by sam smith, and the Best Pop Group Award nominated by Dark Horse with Juicy J was also won by A Great Big World. However, since 2011, "Sister Fruit" has been nominated by Grammy every year, but missed the "Little Horn" award every year. She still runs with me this year, and has become the "Little Plum" Leonardo DiCaprio in music. After 7 years of professional running, it is no wonder that BiBi Zhou has to "swear" to defend his idol in Weibo, saying, "Damn it. Don’t hack my fruit sister again. If you don’t give a prize after running for seven years, you will summon the dragon next year. "

Sam smith’s fame experience

    Born in London, England on May 19th, 1992, he joined the British Youth Music Troupe in 2007 and participated in "Oh! Carol "performance. In 2012, the single Latch by Sam and Decryption Brothers was released, and on May 19th, 2013, the single La La La Sam and Naughty Boys was released, reaching the top of the UK singles charts and ranking 11th in the UK singles charts. In January, 2014, Sam became the champion of BBC TV’s "Voice of the Year". Since then, like his predecessors, he has stepped towards Grammy with solid singing skills and unique style. In May 2014, Sam officially came out, admitted that he was gay, and said that his first album was about his unrequited love.

Financial observation: trade policy is "fiercer than tiger". American enterprises are miserable and embarrassed

  Xinhua News Agency, Washington, June 13 th, financial observation: Trade policy is "fiercer than tiger" and American enterprises are miserable and embarrassed

  Xinhua News Agency reporter Xu Yuan

  The destructive trade policy of the American government is becoming the biggest threat to the development of American enterprises. In recent days, from enterprises to trade associations, from large companies to small and medium-sized enterprises, business people have criticized the US government’s protectionist measures.

  On behalf of 661 American enterprises and trade associations, the American lobbying organization "Tariffs Hurt the Hinterland of the United States" sent a letter to US President Trump on 13th, urging the US government not to impose tariffs on goods imported from China, and to return to the negotiating table to reach a solution with China.

  The open letter warns that American enterprises and trade associations are worried about the situation of tariff escalation. The increase in tariffs and the uncertainty surrounding Sino-US trade negotiations have caused market turmoil and posed a threat to the US economy.

  According to the survey released by the Business Roundtable composed of executives of large American enterprises on the 12th, the "Economic Outlook Index" fell by 5.7 points to 89.5 points in the second quarter. This index reflects the sales expectations, capital expenditures and recruitment plans of American business executives for the next six months, and shows that American business circles are increasingly uneasy about the direction of US trade policy.

  "(The US government’s trade policy) is increasing the risk of bad economic results," said Jamie Dimon, CEO of JPMorgan Chase and chairman of the Business Roundtable at the press conference that day. "The uncertainty of trade policy, the weak global economic growth and the inaction of the US government on other urgent public policy issues are worrying."

  Tom Linebarger, chairman and CEO of Cummins, an American engine manufacturer, said that "trade (policy) is the most terrible threat to enterprise growth". He said that imposing tariffs on China’s goods exported to the United States would increase consumers’ costs and reduce the competitiveness of American enterprises.

  American financial data software company predicts that due to the uncertain tariff policy and global economic prospects, for those multinational companies whose sales are more than half from outside the United States, their profits in the second quarter may drop by 9.3%. The company expects that Apple’s profit may drop by 14.6% in the second quarter, and Boeing’s profit may drop by as much as 43.7%.

  The U.S. government previously announced that the tariff rate on the $200 billion list goods imported from China will be increased from 10% to 25% from May 10, 2019. The U.S. government also threatened to impose a 25% tariff on the remaining about $300 billion of goods exported from China to the United States, involving many end consumer goods.

  Lorraine Hutchinson, an analyst at Bank of America Merrill Lynch, predicts that tariff escalation will lead to growth risks for American retail enterprises such as clothing. According to the semi-annual survey recently released by institute for supply management, about 59% of American enterprises indicated that increasing tariffs would lead to higher product prices. Wal-Mart, an American retail giant, also said that tariffs will force it to raise the retail price of goods.

  Tariffs not only hit large enterprises, but also make life more difficult for small enterprises. USA Today reported a few days ago that the negative impact of tariffs has exhausted the energy of many small American enterprises because their cost digestion ability is worse than that of large enterprises. Adjusting the supply chain will cost hundreds of thousands or even millions of dollars, which is unbearable for many small enterprises.

Dare to try, dare to break through, and change independently! Ten-year exploration of free trade zone leads to a new pattern of opening up

  In September 2013, the Shanghai Pilot Free Trade Zone was formally established and set sail. In September 2023, the construction of China’s Pilot Free Trade Zone ushered in its 10th anniversary. Starting from Shanghai’s 28.78 square kilometers, it has been continuously expanded to about 38,000 square kilometers. In the past ten years, after six expansions, there have been 21 free trade zones and Hainan Free Trade Ports across the country, forming an innovative pattern of reform and opening up covering the east, west, north and south, and coordinating the coastal, inland and border areas, which has effectively explored and accumulated valuable experience for comprehensively deepening reform and opening up.

  Ten years of hard work has yielded fruitful results, and it has accumulated a lot of brilliance. In the past ten years, the Pilot Free Trade Zone has launched a large number of basic and pioneering reform and opening-up measures in line with international common rules, formed many landmark and leading institutional innovations, cultivated a number of internationally competitive industrial clusters, stood at the forefront of China’s high-level opening-up, actively served major regional strategies, coordinated regional development strategies and jointly built the "Belt and Road", and achieved remarkable results.

  In the past ten years, a total of 302 institutional innovations have gone from the China Pilot Free Trade Zone to the whole country, and more than 2,800 have been promoted and copied by various provinces, autonomous regions and municipalities, giving full play to the demonstration, leading and driving role of the Pilot Free Trade Zone, forming a good situation of sharing reform dividends and opening up the fruits to all. In 2022, the actual use of foreign capital in 21 pilot free trade zones was 222.52 billion yuan, accounting for 18.1% of the country. Among them, the actual use of foreign capital in high-tech industries was 86.34 billion yuan, a year-on-year increase of 53.2%. The total import and export volume of 21 pilot free trade zones reached 7.5 trillion yuan, up 14.5% year-on-year, accounting for 17.8% of the country; In the first half of this year, 21 pilot free trade zones accounted for 18.4% of the country’s foreign investment with a land area of less than four thousandths, and the actually used foreign capital reached 129.66 billion yuan, an increase of 8.2% year-on-year.

  Since its establishment, China Pilot Free Trade Zone has been guided by high-level opening, and has made great efforts to explore an institutional system linked with international economic and trade rules. It has also made important breakthroughs in trade, investment, finance, and transformation of government functions, including taking the lead in implementing the national treatment plus negative list management model before foreign investment access, taking the lead in establishing a trade facilitation model centered on the "single window" of international trade, taking the lead in promoting the comprehensive opening of the service industry represented by the negative list management model of cross-border service trade, and taking the lead in implementing the "license separation". … In the past ten years, a number of firsts have been practiced and explored in the Pilot Free Trade Zone and copied to the whole country, creating a vivid model of China’s opening up and development, becoming the "vanguard" leading the country’s deepening reform in the new era, injecting stabilizers and providing new impetus for China’s economic stability and prosperity.

  Bold trials, bold ventures and independent reforms, the fruitful results achieved in the Pilot Free Trade Zone in the past ten years come from innovation and opening up. Through a series of pioneering practices, the Pilot Free Trade Zone has continuously promoted the liberalization and facilitation of trade and investment and continued to lead the opening up. Since 2013, the negative list of foreign investment access in the Pilot Free Trade Zone has been reduced seven times, from 190 to 27 today, realizing the clearing of manufacturing items and the continuous expansion of service industry opening. Hainan Free Trade Port launched the first negative list of cross-border service trade, which realized the fundamental change of service trade management mode.

  In addition, 21 pilot free trade zones across the country actively strengthened collaborative innovation, explored and promoted coordinated development, amplified the comprehensive effect of reform, and achieved positive results. For example, Beijing, Tianjin and Hebei Pilot Free Trade Zone established the Beijing-Tianjin-Hebei joint conference system, launched 153 items of "colleagues with the same standard" in government services, and implemented regional general office to serve the coordinated development of Beijing-Tianjin-Hebei. Shanghai, Jiangsu, Zhejiang and Anhui Pilot Free Trade Zones have established the Yangtze River Delta Pilot Free Trade Zone Alliance to create a mechanism for seeking common development, promoting innovation and sharing results, and achieved institutional innovation results in building a "single window" for international trade in the Yangtze River Delta and building an integrated oil and gas trading market. The Yellow River Basin Pilot Free Trade Zone Alliance will be established along the nine provinces of the Yellow River, and four cooperation mechanisms will be established, including "integrated construction" of social credit system, "integrated management of administrative examination and approval services", "integrated cooperation" of intellectual property protection and "integrated and smooth logistics and transportation services". Guangxi Pilot Free Trade Zone actively builds the most convenient seaport in the western region, effectively strengthens the connection with the backbone channels in southwest, northwest and central south, and serves the western development. Yunnan, Guangxi, Heilongjiang and other pilot free trade zones along the border plan to jointly promote the development and opening up along the border. The joint development of these pilot free trade zones has expanded the breadth and depth of institutional innovation, enriched the application scenarios of free trade policies, and expanded the dividend effect of free trade.It is of great significance for improving the efficiency of reform and innovation, serving to build a new development pattern, and effectively supporting the high-quality development of the free trade pilot zone.

  Standing at a new starting point in ten years, the Pilot Free Trade Zone has ushered in new tasks. At the end of June this year, the State Council issued a document, taking the lead in conducting pilot projects in five qualified free trade pilot zones and Hainan Free Trade Port, such as Shanghai, Guangdong, Tianjin, Fujian and Beijing, connecting with international high-standard economic and trade rules, promoting institutional opening, and exploring ways for comprehensively deepening reform and opening up. The Ministry of Commerce will also work with relevant localities and departments to formulate a list of key tasks in the Pilot Free Trade Zone, clarify 164 key tasks to be independently promoted by the relevant pilot free trade zones in the next three years, further strengthen classified guidance, and promote the deepening of reform, practice and innovation in each pilot free trade zone according to local conditions.

  Sharpen a sword for ten years and stride forward again. This year marks the tenth anniversary of the construction of China Pilot Free Trade Zone, and it is also the first year to implement the "strategy of upgrading the Pilot Free Trade Zone". On the new journey, on the basis of comprehensively summing up ten years’ construction experience, we should thoroughly implement the promotion strategy of the Pilot Free Trade Zone, carry out exploration in a wider field and at a deeper level, and strive to build a higher level pilot free trade zone. For example, we should speed up the pilot work of comprehensively docking international high-standard economic and trade rules, and further promote the institutional opening of rules, regulations, management and standards; Promote a reasonable reduction of the negative list of foreign investment in the Pilot Free Trade Zone, promote the introduction of a negative list of cross-border service trade, and lead the country to continue to expand and open up; Strengthen the overall planning and system integration of reform, thoroughly implement the upgrading strategy of the Pilot Free Trade Zone, and focus on launching a number of leading and integrated reform measures in key areas; Support their respective trade pilot zones to further deepen differentiated exploration and promote the innovative development of the whole industrial chain around key areas … … Let the seeds of institutional innovation in the Pilot Free Trade Zone take root and bear fruit nationwide, promote economic growth to rely more on innovation, and lead China’s high-quality economic development!

Chen Hualan: the "flu detective" who stopped the virus.

Cctv newsVirus is a word that makes people turn pale and avoid it. However, there is such a scientist who, despite difficulties, has played a key role in successfully stopping the avian influenza epidemics such as H5N1 and H7N9 in China. She is Chen Hualan, director of the National Avian Influenza Reference Laboratory and academician of the Chinese Academy of Sciences.

The National Avian Influenza Reference Laboratory of Harbin Veterinary Research Institute of Chinese Academy of Agricultural Sciences, which she led, built a safety "epidemic prevention wall" by relying on a number of international leading achievements independently developed, and contributed China’s wisdom and strength to the prevention of avian influenza in many countries around the world.

Where is the initial heart?

In 1999, as a postdoctoral fellow, Chen Hualan went to the Influenza Sub-center of the Centers for Disease Control (CDC) in the United States to conduct cooperative research on avian influenza. After the exchange, the other party kindly retained him, but Chen Hualan resolutely embarked on the road of returning home.

"It doesn’t matter if the conditions are backward, we can build it slowly." Chen Hualan said that China is a big country for raising poultry. Once bird flu breaks out, it will inevitably suffer great losses if it lacks effective means. "Since the knowledge and technology I have mastered are urgently needed by the country, why don’t I come back?"

Highly pathogenic avian influenza is a class A infectious disease. Once the bird flu epidemic is found all over the world, the common way is to cull all the poultry in a certain range. Doing so not only consumes huge human and financial resources, but also brings disaster to the aquaculture industry.

"Why not seek a better solution?" Chen Hualan, who has just returned to China, boldly proposed, "It is ‘ to develop a new and efficient vaccine for prevention and control; Four or two thousand catties ’ The best choice. " The laboratory she led was designated as the "National Reference Laboratory for Avian Influenza" by the Ministry of Agriculture, responsible for the epidemic diagnosis, epidemiological monitoring and prevention and control technology research of highly pathogenic avian influenza.

At the beginning of 2004, H5 subtype highly pathogenic avian influenza raided 14 provinces in China. The National Reference Laboratory for Avian Influenza receives samples from all over the country for final identification every day. In a short time, more than 50 cases of highly pathogenic H5N1 avian influenza were diagnosed, which played a key role in controlling the epidemic in time. 

Chen Hualan led the team to speed up the pace of vaccine research and development. In more than a year, they completed the research on the new avian influenza vaccine in the laboratory. The successful development of H5N1 and H5N1 avian influenza vaccines has greatly improved China’s ability to prevent and control avian influenza and saved tens of billions of yuan for the country.

Re-war virus

In March 2013, there were cases of human infection with H7N9 avian influenza in China. The rapid spread of the virus caused a lot of panic in the country and attracted great attention from the international community.

The epidemic situation is like military intelligence, and Chen Hualan has once again started a race against the virus. She and her colleagues sent a number of teams to take samples at the first time, and then immediately conducted research and analysis.

Less than 48 hours after the first infected case was announced, Chen Hualan’s team isolated a similar virus from the samples collected in the live poultry market. According to the research results, Chen Hualan suggested that the live poultry market in infected areas should be closed immediately. After her suggestion was adopted, the number of new infections decreased rapidly.

"Although the H7N9 virus that appeared in 2013 can infect people, it is not pathogenic to poultry, and chickens do not show any clinical symptoms after infection, which makes it difficult to find the virus in time." Chen Hualan later said.

The H7N9 avian influenza virus caused a total of 5 waves of human infections, resulting in 1,567 infections, of which more than 600 people were killed. From October every year to March the following year, it is a high incidence period of human infection with H7N9 avian influenza.

Chen Hualan said: "At the thought that H7N9 avian influenza virus is threatening the lives of thousands of people, we dare not relax for a moment."

In the four Spring Festival after the emergence of H7N9 virus, Chenhualan was spent in the laboratory. But the virus is a tough opponent.

"In January 2017, we found in the monitoring that the H7N9 avian influenza virus had a key mutation, and poultry began to get sick and died in large numbers after infection." The situation that Chen Hualan is most worried about has emerged. "The mutated virus is more harmful to people, and the mortality rate can reach more than 50%."

From January to September, 2017, the "race" between team Chen Hualan and the virus entered a sprint stage: intensify on-site sample collection and pathogen monitoring nationwide, speed up virus analysis and research, formulate prevention and control measures, put forward prevention and control suggestions, speed up the process of creating efficient vaccines, and accept evaluation and testing & HELIP; … Miracle happened like this. Before the arrival of the virus epidemic season in autumn and winter of 2017, Chen Hualan team successfully launched the bivalent inactivated vaccine of recombinant avian influenza virus (H5/H7).

The popularization of the vaccine has effectively controlled the spread of H7N9 avian influenza virus in poultry and successfully blocked the infection of H7N9 avian influenza virus in people.

be as usual

Behind the first-class scientific research is the unimaginable contribution of ordinary people. Team Chen Hualan conducts large-scale avian influenza virus monitoring twice a year, and members go to farms and live poultry markets across the country to take samples from live poultry and bring them back for analysis. When sampling, researchers should use swabs to take samples from the deep throat and cloaca of chickens respectively. In 2017 alone, the team members sampled 53,000 copies. After returning to the laboratory, they must isolate the virus as soon as possible and do further analysis and research.

In addition to epidemic diagnosis and vaccine research, Chen Hualan also led the team to strengthen the active surveillance of avian influenza epidemiology in China and explore the biological characteristics of the virus. By giving full play to the individual strengths of team members, a full chain and systematic influenza research layout has been formed. At the same time, it shoulders the responsibility of providing scientific reference for the prevention and control of bird flu epidemic and early warning of human influenza.

In 2013, Chen Hualan was selected as one of the top ten scientific figures in Nature, and Nature called her "the one fighting in the front line ‘ Influenza detective ’ " . In 2016, Chen Hualan won the "World Outstanding Female Scientist Achievement Award" awarded by UNESCO.

Even though Chen Hualan has stood in the leading position in the world, he and his team are always in a state of "preparing for war". Chen Hualan said: "Avian influenza virus can infect not only poultry, but also migratory birds. Migratory birds who migrate across borders are very free, and they don’t need to fly to any country ‘ Passport ’ . If they carry the virus, an epidemic may occur as soon as they come into contact with local poultry. We must always be vigilant and respond to emerging epidemics at any time. "

Now, the word "avian influenza" has quietly faded out of the sight of ordinary people, while Chen Hualan remains vigilant. "The highly pathogenic avian influenza virus has evolved rapidly, and we can’t relax at all". Some people ask, is it worthwhile to give up many pleasures in life for work? Chen Hualan replied slowly: "Is it more fun and worthwhile for researchers engaged in the prevention and control of infectious diseases to nip the highly dangerous bird flu epidemic in the bud?"

Bombing Macron "stupid", Trump released a meaningful sentence.

  [Global Network Reporter Li Dongyu] "Although I don’t drink, I always prefer American wine to French wine." On July 26, local time, when Trump once again issued a tariff threat to French-made wines, he used this sentence to express his support for domestic wines.

  As a response to France’s recent announcement to levy a digital service tax on global technology giants, according to The New York Times, Trump first said on Twitter on the 26th, "France has just imposed a digital tax on our great American technology companies. If someone wants to tax them, it should also be their motherland — — America. "

  Then, he added, "We will soon announce substantive reciprocal action against Macron’s foolish behavior."

  Interestingly, Trump did not explicitly say what to do, but then meaningfully threw out a sentence, "I have always said that American wine is better than French wine!"

  The New York Times said that shortly afterwards, Trump made another speech at the White House that day, further expounding the threat to France, saying that the French tax was "wrong" and his government was studying a possible wine tax. Trump told reporters, "Although I don’t drink, I always prefer American wine to French wine."

  The New York Times said that this week, French President Macron signed a bill to impose a new digital tax on technology giants, and global Internet giants such as Facebook, Google and Amazon became potential targets. The tax rate is as high as 3%. The US Consumer News and Business Channel (CNBC) said that the Trump administration subsequently launched the 301 investigation under the Trade Act of 1974.

  CNBC said that if after the investigation, the United States determines that this new tax is discriminatory or unreasonably targeted at American companies, Trump may respond with tariffs. Trade experts believe that Trump’s most likely response is to the French iconic product — — There is a 100% (import) tariff on wine.

  "The Trump administration has always stated that it will not stand by and tolerate discrimination against American companies." This is what White House spokesman Judd Deere said in a statement on the 26th local time. The statement criticized France’s tax policy, but did not give any new details about what retaliatory measures the United States might take. Deere said that the government is "closely watching all other policy tools" except the investigation, so as to decide how to respond to France.

  In the face of the tough stance of the United States, according to Agence France-Presse reported on 26th, French Economy Minister lemerre once said that Paris was not scared. "A universal tax on digital activities is a challenge for all of us. We hope to reach an agreement within the G7 and the OECD. At the same time, France will implement its own national decisions. "
