On April 17th, a car owner posted a video on the Internet saying that the metal nameplate of Xiaomi SU7, which he bought, had fallen off. In the video, the netizen introduced it with a metal plate engraved with the number "1089", which was the exclusive nameplate of the car. It was stuck on the steering wheel with double-sided adhesive tape. Because the outermost layer of the nameplate was very sharp, some scratches were drawn on the steering wheel after the nameplate fell off.

"Food partner" and "ball partner" …

More and more "partners"

Become popular among young people

"Partner" is a kind of

Because of a common interest or need

And a social relationship

For railway people,

Due to the particularity of jobs and posts

Many jobs must be done by two people.

Or many people can cooperate to complete it.

Let’s meet.

Those "iron partners" in Wu Tie people’s work

No.1

Scheduling "partners"

In the station dispatching work, station attendant is responsible for receiving and dispatching trains without interruption. In order to ensure the efficient operation of the train, it is inseparable from the cooperation with the assistant attendant (field).

Usually, station attendant will organize the operation according to the stage plan, and inform the assistant attendant (field) of the number of trains, track occupation, arrival and departure, etc. through the train dispatching wireless communication equipment. The assistant attendant (field) will set up a post at the specified place to receive (send) the train, and will report any situation to station attendant in time.

No.2

Driving a "ride"

To drive a locomotive safely, the locomotive driver and the locomotive assistant driver must cooperate closely. When driving a motorcycle, the driver is in charge of driving, and the assistant driver needs to do a good job of looking out for him in operation and inspecting the machinery room on the way.

With the cooperation of the driver and the assistant driver, the safe running of the locomotive and the smooth and comfortable travel experience of passengers can be ensured.

No.3

Welding "partner"

During the rail drilling operation, the operator of the rail welder should check in advance to confirm that the rail verticality reaches the standard, synchronize the drilling grate, and confirm that the eye distance and hole distance meet the standard before drilling operation can be carried out.

In order to control the hole spacing standard perfectly, the assistant must use the water injector to inject water into the drill bit to cool the drill bit during the operation, so as to ensure that the one-time drilling meets the standard.

No.4

Measure the "partner"

When the lineman manually checks the geometric dimensions and track structure of the line, an inspector is responsible for operating the equipment and measuring the geometric dimensions such as track gauge, level, height and track direction of the line.

The recorder on the side will record and analyze with him synchronously, and at the same time help him observe the state of the ballast bed to ensure a comprehensive inspection of the line and not miss a hidden danger.

No.5

Tool "saddle"

When the electrician replaces the equipment clamp of the disconnector rod of the through line of power equipment, the rod-boarding hand is responsible for the maintenance operation and the treatment of equipment diseases such as broken disconnector clamp and loose insulator.

The assistant hand on standby on the ground needs the operator to climb the pole to provide the corresponding tools and assistance for the air operator after confirming the disease, so as to ensure the efficient treatment of the disease in the limited working environment.

No.6

Check the "partner"

When the signalman carries out the check on the consistency of interlocking drawings, one person issues an instruction to find the number of cables according to the drawings, and the other person verifies cables according to the instruction, confirms the whereabouts of cables, checks the integrity of cables, and checks the number of cables with the person who issues the instruction.

Through double verification, the safety and accuracy of cable verification are ensured, and the interlock safety is ensured.

No.7

Overhaul the "saddle"

When the catenary operator adjusts the catenary compensation device, one person is responsible for adjusting the length of the compensation rope at the falling weight of the catenary compensation device and making the compensation rope back.

Another person must use a hand hoist above the anchor post to help him tighten and unload the weight, so as to ensure that the compensation device can be adjusted quickly and standard.

Help each other, promote each other and improve together.

This is the "partner" of railway people.

　　[Pacific Auto Network] Recently, Auto announced its revenue and profit in 2021. According to the official, consumers’ demand for the car is still strong despite the continuous shortage of spare parts in the automobile industry.

　　Specifically, Volvo Car’s revenue in 2021 increased from SEK 262.8 billion in the previous year to SEK 282 billion, an increase of 7%. Operating profit increased from SEK 8.5 billion in the previous year to SEK 20.3 billion, up 138% year-on-year, and the operating profit margin was 7.2%. Net profit increased from SEK 7.8 billion to SEK 14.2 billion, an increase of 82%.

　　"2021 is a proud year for Volvo Cars," said H? Kan Samuelsson said, "Despite the continuous shortage of parts and components in the automotive industry, our global market share has increased and we have achieved unprecedented high income and profit margin."

　　According to official information, in the last quarter of 2021, Volvo Car’s revenue was 80.1 billion Swedish kronor, down 6% year-on-year. Although consumer demand and orders have been strong, automobile production was limited due to the shortage of chips. The operating profit for the quarter was SEK 3.7 billion, and the operating profit rate was 7.1%.

　　Compared with the same period in 2020, the sales of Volvo Cars in the fourth quarter of 2021 decreased by 20%. The company’s electrification series products continue to be welcomed by the market. In the fourth quarter of 2021, the series vehicles accounted for 34% of the company’s global sales, plug-in vehicles accounted for 28% of Volvo’s total sales, and pure electric vehicles accounted for 6% of the total sales.

　　As Volvo Cars increases the annual production capacity of pure electric vehicles to 150,000 vehicles, the proportion of pure electric vehicles in the total sales will double compared with 2021. Looking ahead, Volvo officials said that the uncertainty of the automobile industry is still high. Although the shortage of spare parts has eased, the supply chain is expected to remain a constraint. At the same time, Volvo Cars continues to see strong customer demand and predicts that the growth rate of electric vehicles will be faster than the overall market, which will enable the company’s sales to continue to grow in 2022.

　　BYD’s Electric 2015: Taking "Tang" as "Ming"

　　From 19: 38 to 20: 58, Wang Chuanfu talked about solar energy from oil, smog from disease, and the South China Sea issue from the Straits of Malacca … … For a whole hour and 20 minutes, during the seemingly casual chat, he set the tone for BYD in 2015 at the macro level through his feelings: focusing on new energy.

　　This scene took place at the Yantian Sports Center in Shenzhen on the evening of January 20th, the scene of BYD’s first Difen Conference. In fact, this conference has another name — — BYD’s "World-class Technology Analysis Conference" is held once a year. Presumably, at the last conference, a 70-page brochure, which listed almost all BYD’s technologies, still made the experienced media people remember it vividly.

　　This year’s conference, in addition to changing the name, the theme seems to have changed a little. Don’t talk about electronics, interconnection, cloud and technology … … Just talk about new energy. Starting from the pre-sale price of 300,000 yuan in Tang Dynasty, Song, Yuan and even Ming were mentioned in turn. The 6-engine 4-drive technology killer and the 3.9-second 100-kilometer acceleration time were indeed enough to support the gold content of the most important conference in BYD’s eyes.

　　BYD’s vision of a new energy empire is gradually coming to fruition, starting from the field of public transportation and finally cutting into the personal consumption market. Wang Chuanfu said, "When all this is done, I can retire.".

　　"Tang" at the beginning

　　Last year, BYD Qin accidentally caught fire again. The annual sales volume of 14,747 units, in addition to firmly sitting on the throne of new energy vehicle sales champion, is a real test of BYD’s production capacity. The phenomenon of demand exceeding supply, led by Shanghai, frequently appears in eight cities where Qin landed.

　　Compared with Qin’s dual-engine and dual-mode, after adding a motor, Tang evolved into a three-engine four-wheel drive — — A 2.0TI engine with two motors in front and rear, and four-wheel drive. It is worth mentioning that in terms of four-wheel drive technology, BYD Tang is not equipped with a transfer case and a transmission shaft like the traditional four-wheel drive model, but drives the front and rear axles independently by two motors, and then the power is distributed by a unified control system to realize four-wheel drive. With the peak torque of the front and rear motors of 250Nm and the maximum power assistance of 110kw, Tang’s 100-kilometer acceleration performance after technical optimization increased from 5.9 seconds in Qin Dynasty to 4.9 seconds.

　　In order to highlight Tang’s acceleration performance, BYD specially arranged the test drive experience of the car on the morning of the conference. Although due to the limited number of vehicles, not every media and Difen has the opportunity to experience it, according to the participants who experienced it, Tang’s sense of acceleration is somewhat similar to Tesla Model S, with a strong sense of pushing back and even a brief dizziness. Judging from the results of the 200-meter linear acceleration, Tang’s performance was basically stable at around 7.9 seconds when he took four people in the car.

　　In the driving mode, Tang offers the choice of HEV (four-wheel drive+sports+hybrid mode) and EV (four-wheel drive+economy+pure electric mode). The former focuses on performance, and the engine and motor work together, with the best power; The latter focuses on economy, and the power battery provides electric energy to drive the vehicle with the power supply machine.

　　If the vehicle is short of power in EV mode, the system will automatically switch from EV mode to HEV mode, and use the engine to drive. When the vehicle is driving at a relatively stable medium and high speed, part of the torque output by the engine will drive the front motor to generate electricity, and the rear motor will drive, giving consideration to economy and four-wheel drive.

　　As the highlight of the conference, Tang announced the pre-sale price of 300,000 yuan and 600,000 yuan. Interestingly, when BYD was the first to announce the pre-sale price of 600,000 yuan, the friends at the scene were all shocked into a cold sweat. Later, when everyone looked intently, it turned out to be the extreme version of Tang. This price can’t explain the problem, but only show the attitude. The pre-sale price of the ordinary version of Tang is 300,000 yuan, which Che Yun thinks is reasonable. With the subsidies from each city, the sales volume of this car is expected to surpass that of Qin.

　　Interestingly, within 12 minutes after the official acceptance of the reservation at 5: 42 on January 21, the first batch of 100 Tang cars, including 98 regular models and 2 extreme models, were quickly declared sold out.

　　"Song and Yuan Dynasties" Follow-up

　　In April last year, BYD released the "542 Strategy", in which "5" means that all models are accelerated within 5 seconds at 0-100km/h, 4 represents all-round four-wheel drive and 2 represents fuel consumption within 2L per 100 km. As the first model of this strategy, Tang is just the beginning.

　　Lian Yubo, senior vice president of BYD Co., Ltd. and chief engineer of automobile industry group, said that after Tang Dynasty, Song and Yuan will join the "542 Strategy" vehicle camp in the second and third quarters of this year, because both Tang, Song and Yuan models are SUVs, and 2015 will be BYD’s "SUV Year".

　　At the press conference, Song Heyuan’s model parameters were also announced for the first time.

　　It is reported that Song is located in a compact SUV, equipped with a dual-mode full-time electric four-wheel drive system. The powertrain consists of 1.5TI+DCT+ motor, with a vehicle mass of 2000kg, a length, width and height of 4,565/1,830/1,720 mm respectively, and a wheelbase of 2,660 mm. Yuan’s size is smaller than Song’s, and it is also equipped with a dual-mode full-time electric four-wheel drive system. The vehicle’s mass is 1850kg, its length, width and height are 4320/1765/1650mm respectively, and its wheelbase is 2520 mm.

　　Of course, don’t forget the business. Although it is not an SUV, this MPV model, which was unveiled at last year’s Beijing Auto Show, is also part of BYD’s lineup of new energy vehicles. The company is equipped with dual-engine dual-mode technology, and its hybrid system consists of a 1.5L gasoline engine with a maximum power of 80kW and a 110kW motor, with a combined maximum power of 190kW. It is reported that the car’s comprehensive fuel consumption per kilometer is 2.24L, and the acceleration time of 100 kilometers is only 7.5 seconds, which is MPV… … ..

　　In addition, in the interview after the press conference, a model named Han was also revealed by Wang Chuanfu, but he did not further disclose the specific parameters and launch time of the car.

　　The "Ming" of the finale

　　In Wang Chuanfu’s view, BYD’s limit in the field of new energy vehicles is far more than that, and they are "making big moves". BYD said last year that "Tesla was built in minutes", and now this car is really coming.

　　At the press conference, Lian Yubo said that BYD will launch the first six-engine four-wheel drive model "Ming" in 2017, which is equipped with an engine and five motors. The five motors are one series motor and four motors that drive four wheels respectively. In BYD’s eyes, this is a six-engine four-wheel drive dual-mode "big killer", and the acceleration time of 100 kilometers will reach 3.9 seconds.

　　Wang Chuanfu introduced that in addition to performance optimization, the biggest feature of "Ming" is safety. "Traditional mechanical vehicles are single-point. In the electronic age, they can be driven in a distributed way. Each wheel corresponds to a motor to achieve a negative 100% torque. In 600 milliseconds, many actions can be done to stop traffic accidents by electronic control."

　　In addition, Wang Chuanfu revealed that with the technical support of six-engine four-wheel drive, BYD will develop an active safety system, including the functions of car body self-balancing, braking failure prevention, steering failure prevention, rollover prevention and side slip prevention, all of which are intelligently adjusted by driving the wheels of the motor.

　　Charging matching

　　In addition to the product itself, BYD also publicly displayed the charging tower of pure electric vehicle in the air and the 3+3 circulating stereo charger in Shenzhen Pingshan factory for the first time on the morning of the conference, and released relevant data.

　　BYD Tower has 10 floors, and adopts a rotating tower structure. 40 cars can be parked on a single floor, and 400 cars can be parked and charged at the same time on the 10th floor. The 40kW fast charging equipment can fully charge BYD E6 within 2 hours. It is reported that the total power of the entire charging tower is 14400kW. In the charging tower, users can observe the charging status of vehicles in real time through the LED screen in the lounge.

　　In addition, the total parking capacity of the 3+3 circulating stereo charger is 72 sets, and there are 2 sets of parking devices consisting of 3 units, each unit can park 12 cars. It is reported that each parking space is equipped with charging equipment with a power of 40kW and a total installed capacity of 2950kW (including lighting and air conditioning). According to the charging time, 216 vehicles can be served every day.

　　Che Yun summary:

　　Since it set foot in the automobile industry, BYD has always been questioned, speculated and criticized. It is true that we must recognize its problems, such as the matching of vehicle workmanship details with core technologies, such as the capacity problem after the expansion of new energy vehicle product line this year, and so on. However, we should not deny its advantages, such as its corporate engineer culture.

　　By the way, in addition to the product itself, BYD has made some progress this time. They gradually realized the value of Difen to themselves. This is a group of people who know BYD better than BYD himself and the media. This conference set up a link where Di Fen represented Wang Chuanfu as a gift. This gift was nothing but a suggestion made by Di Fen to BYD. When Wang Chuanfu received this heavy gift, he choked when he spoke.

　　

　　Original title: BYD Han EV test drive evaluation: luxury and technology live up to the name of flagship

　　Beijing, September 6 (Reporter Zhang Xu) Since the listing of Han EV, it has become BYD’s hottest pure electric car. As a flagship model, it integrates all new technologies and technologies. Brand-new design language, luxurious interior atmosphere, blade battery, IPB intelligent brake and Dillink 3.0 intelligent network connection system are all applied to Han EV, and they live up to the name of flagship.

　　Another Deduction of Oriental Aesthetics

　　Han EV adopts the latest EV Dragon face family design language. Compared with the previous EV models, it simplifies the exaggerated big mouth grille design and replaces it with this widened matte metal trim. The flat design is not only simple and elegant, but also improves the sense of the whole front.

　　The shape of the headlights is slender and magical, and its light source adopts a matrix LED light group. When you unlock the vehicle, LED daytime running lights and LED headlights light up in turn, just like waking up a sleeping dragon, which is very sci-fi. At the same time, the inner folding line design of the lower part of the front bumper with the figure-eight diversion duct not only enriches the shape of the front face, but also brings a strong sense of movement. This brand-new design style has become a unique symbol of BYD EV models.

　　From the side, the first impression of Han EV is long, very long. As a flagship model, its body length reaches 4980mm, its width is 1910mm, and its height is only 1495 mm. Together with the wheelbase of 2920mm, it makes the whole look very long and narrow. The through waistline creates a dive posture, and the design that the arched lines at the rear fender are combined with the tailgate cover shows the car’s sense of strength and movement to the fullest.

　　In fact, there are some hidden design details and technical configurations on the side of the car body. The first is the hidden electric door handle, which increases the sense of ceremony and also reduces the wind resistance. In addition, the extended door handle is engraved with the LOGO of "Han". This detail is handled very delicately, which always shows the identity of the flagship model.

　　Secondly, the exterior rearview mirror similar to the shape of water droplets can further support the reduction of wind resistance. NFC function logo is also marked on the exterior rearview mirror. When you forget to bring your car keys when you travel, you can easily do it with your mobile phone, which is convenient and practical. In addition, thanks to the smooth body lines of the whole vehicle and these fine designs, Han EV can have a drag coefficient of 0.233.

　　The design of the rear of the car is still simple and clear. The rear is formed by multiple horizontal lines, which makes the overall visual width even better. The through taillights are decorated with silver chrome, which looks very delicate. The most special thing is that the taillights incorporate the design elements of the dragon claws, and the red light strips inside are very beautiful after lighting.

　　Luxury and technology coexist.

　　The center console of Han EV is still a familiar dynasty series style. The rotatable central control screen is eye-catching. The leather package that can be reached everywhere is matched with wooden decorative boards and leather stitching, which creates the texture and luxury atmosphere of the whole interior in a very good position.

　　In fact, sitting in the car, the first impression is not this luxurious and scientific center console. It’s the seat of Han EV, which is really comfortable. The seat is made of perforated leather, which is in place for leg support, waist support, wrapping on both sides and head support, and the padding of the seat is very soft, just like sitting on a soft and supportive leather sofa. In addition, the seat is also equipped with ventilation and heating function, which can bring high-quality riding experience in winter and summer.

　　The steering wheel is designed with a flat-bottomed Shuang Fu, with excellent grip and reasonable layout of multi-function buttons on both sides, making it easy for people to find the corresponding functions.

　　It is not surprising that the 12.3-inch full LCD dashboard appears on BYD models, and the information that can be displayed is also very rich, and it provides three theme modes: classic, concise and sports. However, with the switching of ECO/SPORT driving modes, each theme will also present two different color backgrounds.

　　BYD’s latest DiLink3.0 car system is installed in this 15.6-inch rotating screen. The brand-new UI design is the biggest change of the new system. Its design is inspired by Tai Chi and ancient jade elements, and with high resolution and good response speed, the central control screen has excellent visual sense and practicality.

　　Han EV’s gear area was officially named "BYDHeart Dragon’s Heart". Its brand-new gear is small and full to grasp, and the layout design of surrounding buttons also improves the convenience of operation. This area is equipped with multiple function buttons such as automatic parking, volume adjustment, driving mode adjustment, kinetic energy recovery adjustment, etc. However, there are also some regrets. Bright black is seriously reflective in the case of sufficient light, and it is still difficult to operate this area while driving.

　　Sitting in the back row, the comfort of the seat is as good as that of the front row. The head, back and legs are well supported and wrapped, and the padding in the seat is soft enough. In addition, the boss key, the co-pilot, and the independent air conditioning control panel in the back row are standard in all the EV systems.

　　Beyond the driving experience of the same level

　　The model we tested this time is the distinguished version of Han EV with long battery life. It adopts the power layout of single motor precursor, and is equipped with a permanent magnet synchronous motor with the maximum power of 163kW and the maximum torque of 330N·m, and the acceleration from 0 to 100 km/h is 7.9 seconds. Although it is not as fast as 3.9 seconds per 100 kilometers of the four-wheel drive high-performance flagship model, it can only make a choice in order to have a battery life of 605KM.

　　BYD’s blade battery is the highlight, and the space utilization rate inside its battery pack can be improved by 60%-80% compared with the traditional battery pack. This also makes the battery capacity reach 77kWh and the energy density reach 140Wh/kg.

　　In daily driving, the accelerator pedal and brake adjustment of Han EV are more like a fuel car. When the vehicle starts to accelerate, the power output of the motor is linear and uniform without any sudden feeling. When braking, the vehicle will stop linearly according to the driver’s braking force. It is worth mentioning that when the vehicle decelerates at low speed, the initial braking force is slightly stiff, but the situation has improved after the adjustment of the comfort of the brake pedal.

　　The new car offers three driving modes, except snow mode, ECO and SPORT are the two most commonly used modes. Because it is a single motor model, when driving in ECO or SPORT mode, I feel that there is not much difference between them, but the dynamic response of the latter is faster.

　　In addition, the car also provides standard and large two-stage kinetic energy recovery adjustment. When the kinetic energy recovery is in the standard mode, after releasing the accelerator pedal, the vehicle will slow down like a fuel truck without any dragging feeling; When the kinetic energy recovery level is high, although the vehicle will obviously slow down, it does not bring a strong sense of drag, and the whole kinetic energy recovery process is smooth and natural.

　　Han EV has excellent control over NVH. In terms of wind noise, thanks to the double-layer glass in the front row, almost no obvious noise can be heard within 100km/h, and the interior quietness is very satisfactory. Compared with the former, the performance of tire noise is slightly inferior. When the vehicle passes through some rough sections, the noise is more obvious, but it is within the acceptable range.

　　The car adopts the combination of front McPherson independent suspension and rear multi-link independent suspension, and the chassis suspension is set with toughness, which ensures the comfort of the car and has certain support. In the face of bumps such as speed bumps, manhole covers and damaged roads, it is handled properly without unnecessary shaking, but the vibration filtering effect is slightly not calm enough for continuous fine vibration.

　　summary

　　On the whole, the performance of Han EV is quite outstanding. Whether it is the appearance value, interior materials, high configuration and technical strength, it is well-deserved as BYD’s flagship car. And it can meet the needs of many consumers for space, quality and configuration at a price of less than 300 thousand yuan, which may be the secret of keeping sales of Han EV.

Recently, the car announced that,
(
get away
) The car was officially rolled off the assembly line. The car has been put on sale at this year’s Shanghai Auto Show. There are three models with 52km and 112km pure battery life, and the price range is 189.8-21.68 million yuan. According to the official introduction, as a new derivative version of the Tang family, the comprehensive fuel consumption of new cars equipped with the new DM-i plug-in system will be as low as 5.3(5.5)L/100km.

After several months of fermentation, we should already be familiar with the Tang DM-i, which is a brand-new high-end SUV model on the MD-i platform. The internal and external design and the cash Tang,
-P Similar, the family-style Dragon Face design language is still fashionable and avant-garde, and the design elements such as blue-eyed LED headlights, penetrating taillights and the "Build Your Dreams" logo at the tail are highly recognizable.

In terms of size, the "measurements" of 4870/1950/1725mm and the wheelbase of 2820mm also fully established its status as a luxury seven-seat SUV, and the 20-inch thin banner wheel hub and blackened components surrounded by the front and rear further highlighted the dynamic temperament.

In the interior part, the central control layout is still a familiar family-style design idea. Symbolic elements such as two-spoke steering wheel, full LCD instrument panel, rotatable central control panel and electronic shift lever are all reflected, and vertically arranged air conditioning outlets are also very distinctive.

In the power system, the new car is equipped with BYD’s newly developed DM-i super hybrid system, which consists of a 1.5T hybrid engine (Miller cycle, variable cross-section turbine, 350Bar direct injection, electric drive compressor, electric drive oil pump/water pump), two off-axis dual motors and EHS electromechanical coupling mechanism. Among them, the maximum power of the engine is 102kW, and the front axle motor can output an additional power of 145kW or 160kW. The 0-100km/h acceleration time of EHS160 version is 8.5 seconds.

As a plug-in hybrid car, the new car is also equipped with blade batteries with capacities of 9.98kWh and 112kWh respectively, and its pure electric cruising range is 52km and 112km respectively. According to official data, the overall fuel consumption of the vehicle is only 5.3L/100km and 5.5L/100km； without charging at all. The NEDC cruising range of a new car with full fuel and electricity can reach 1010km and 1050km, which is significantly ahead of all pure fuel vehicles or pure electric vehicles.

　　When you browse the latest news of the Nobel Prize with your mobile terminal, do you think of the power supplier of your mobile terminal — — Lithium battery is the result of this year’s Nobel Prize!

　　On the afternoon of October 9th, Beijing time, the Royal Swedish Academy of Sciences announced that it would award the 2019 Nobel Prize in Chemistry to Professor John Goodenough, Professor Stanley Wittingham and Dr. Yoshinoya for their outstanding contributions in the field of lithium batteries.

　　How can lithium batteries, which are widely used in people’s daily lives, become Nobel Prize achievements? This has to start with the study of "batteries replacing oil".

　　In 1973, the fourth Middle East War caused the first oil crisis. The developed countries such as the United States realized the importance of getting rid of oil dependence and began to invest in battery research — — Battery can not only replace oil as a new energy source for automobiles, but also be an energy storage device for renewable energy such as solar energy and wind energy. Therefore, the enthusiasm of countries to develop this kind of battery is unprecedented.

　　The first breakthrough was Stanley Whitingham. He drafted the initial design scheme of lithium battery: titanium sulfide as cathode material and lithium metal as cathode material — — This proved to be a rechargeable battery. The energy density problem of battery materials, which has puzzled scientists for more than one hundred years, has also been solved by Wittingham one by one.

　　However, with the passage of time, it has been found that it is not safe to use metallic lithium as the negative electrode. The lithium battery will continuously precipitate dendrites with the increase of usage times, which will eventually cause the battery to spontaneously ignite.

　　Is there a solution to this problem? Professor Goodenough, who is 97 years old and the oldest winner in the history of the Nobel Prize, has made great contributions.

　　In 1980, Goodenough team proposed and found layered oxide cathode material — — Lithium cobalt oxide, which is still used in all kinds of mainstream consumer electronic products, and the negative electrode of lithium aluminum alloy, has brought mankind into the era of portable mobile phones and notebook computers.

　　In 1997, 75-year-old Goodenough and his team developed another more stable and safe cathode material, Ferrous lithium phosphate. It is the mainstream material for batteries used in electric vehicles, electric buses, electric ships, large-scale energy storage, communication base stations, data centers and so on.

　　Only a wider application can promote the further development of lithium batteries. How to integrate the experimental battery materials into usable devices and really apply them to small objects? Japanese scientist Akira Yoshino did it.

　　In 1990, after 10 years’ research, Akira Yoshino, then a researcher in a company, successfully used carbon instead of lithium alloy as the negative electrode of the battery. Combined with the lithium cobaltate positive electrode of Goodenough, this battery became safer and greatly reduced the risk of spontaneous combustion.

　　According to Yoshino Akira’s research, Sony officially launched the world’s first commercial lithium battery in 1991. Subsequently, they replaced the carbon cathode with graphene, which further improved the safety, energy density and cycle life of the battery.

　　Compared with lead-acid battery and nickel-silicon battery, lithium battery has the advantages of high energy density, long life and no memory effect, and is an excellent battery.

　　Back then, the invention of electric vehicles was much earlier than that of internal combustion engines. However, with the continuous improvement of internal combustion engine efficiency, the battery energy density is not high enough, which makes electric vehicles fade out. Now, electric vehicles have returned to people’s field of vision. An important premise is that lithium batteries, which were originally used to replace oil, have finally assumed an important historical mission.

　　At present, the global lithium battery industry is close to 50 billion dollars, and it is growing at a rate of more than 10% every year. Lithium battery has penetrated into all aspects of human life, and its invention has supported the continuous development of high technology in human society.

　　Obviously, lithium batteries have become the result of the Nobel Prize, and they deserve it!

　　Sino-US tariffs welcome new news.

　　Late at night on December 26th, Beijing time, the Office of the US Trade Representative announced that it would further extend the 301-clause tariff exemption period for 352 imported goods from China and 77 imported goods from China related to epidemic prevention in COVID-19, from December 31st this year to May 31st, 2024.

　　Huawei successfully screened the screen today!

　　Look at the detailed report!

　　The Office of the United States Trade Representative announced that

　　On December 26th, local time, the Office of the US Trade Representative announced that it would further extend the 301-clause tariff exemption period for 352 imported goods from China and 77 imported goods from China related to epidemic prevention in COVID-19, from December 31st this year to May 31st, 2024.

　　Prior to this, on September 6th, the Office of the US Trade Representative also announced that it would further extend the 301 tariff exemption period for 352 imported goods from China and 77 imported goods from China related to epidemic prevention in COVID-19, and the period would be extended from September 30th to December 31st this year. On September 7th, China’s Foreign Ministry spokesperson Mao Ning said that as a matter of principle, we have always opposed the fight against tariff war, thinking that there is no winner in tariff war. The unilateral imposition of tariffs by the United States on China violates WTO rules, which is unfavorable to China, the United States and the world.

　　According to previous media reports, during Trump’s administration, he invoked Section 301 (commonly known as Section 301 of the US Trade Act of 1974) in the name of "national security" to impose tariffs on China’s imported goods. During the Trump administration, there were more than 2,200 goods exempted from tariffs, of which 549 products were extended for one year, but all exemptions expired at the end of 2020. In October, 2021, the Office of the United States Trade Representative announced that it planned to re-exempt 549 imported goods from China, and solicited public opinions on this. After a lapse of nearly half a year, the Office of the US Trade Representative issued a statement on March 23, confirming 352 of the 549 imported goods from China that were to be exempted from tariffs again. This tariff exemption period has been extended many times so far.

　　In March 2022, Shu Jueting, spokesperson of the Ministry of Commerce, said at the press conference that China noticed that on March 23, the Office of the US Trade Representative announced that it would resume exempting 352 items of goods imported from China from additional tariffs, which would help the normal trade of related products. China has always believed that the unilateral tariff increase measures of the United States are unfavorable to China, the United States and the world. Under the current situation that inflation continues to rise and global economic recovery is facing challenges, it is hoped that the United States will cancel all tariffs on China as soon as possible from the fundamental interests of consumers and producers in China and the United States, and push bilateral economic and trade relations back to normal track as soon as possible.

　　The M9 in Wenjie is selling like hot cakes.

　　On December 26th, Yu Chengdong, managing director of Huawei, CEO of BG, and chairman of BU, a smart car solution, officially released the M9 at the press conference of the world of inquiry and the whole scene of Huawei in winter, with the price starting from 469,800 yuan.

　　With the launch of new cars, there are three models under the brand of Wenjie: M5, M7 and M9. Together with the Zhijie S7, which cooperated with Chery not long ago, Huawei HarmonyOS Zhixing currently has two brands, namely Wenjie and Zhijie, and four models are on sale. In the future, Huawei will also work with BAIC andCooperate with new "Jie" generation brands and new models.

　　It is understood that intelligent car selection is the deepest cooperation mode between Huawei and automobile companies. Huawei not only provides key technologies such as intelligence, but also deeply participates in product definition and development, and also opens its own terminal channels to help sell cars. Previously, Huawei upgraded the smart car selection mode to HarmonyOS Zhixing.

　　It is the first partner of Huawei HarmonyOS Zhixing, and released the first intelligent car selection product in April 2021. In 2022, the sales volume of the brand series products created by both parties reached 75,000, which was once the fastest growing in China.Brand. However, in the first half of this year, the world encountered Waterloo, and the monthly sales volume once fell to more than 3,000 vehicles.

　　According to Blue Whale Financial News, it was learned from insiders close to Huawei that AITO will launch the new M5 in the first half of next year, and the brand-new M8 between M7 and M9 will also be launched in the second half of next year.

　　A-share "Huawei" want to be embarrassed again?

　　In the secondary market, this year,Concept stocks have been active repeatedly. Although they have been adjusted with the broader market recently, the Wind index still rose by more than 11% during the year, significantly outperforming the broader market index. In terms of individual stocks,The increase during the year exceeded 440%., Cyrus rose by more than 100%,、Wait for the increase to exceed 40%.

　　Recently, Huawei Technologies Co., Ltd. applied for registration of "Zunjie" and "Qingjie" trademarks, which are internationally classified as means of transport and scientific instruments, and the current trademark status is awaiting substantive examination. Previously, Huawei had applied for a series of trademarks related to the world, including Wen, Zhi, Yong, Hui, Zhu, Ao, Zhi and Yi. Not surprisingly, most of these "Jie" trademarks are prepared for HarmonyOS Zhixing Ecological Alliance. The above news once triggered a rise in concept stocks.

　　Recently, it was pointed out that Huawei vigorously laid out its automobile business, and the three models enabled automobile enterprises to build and sell good cars from simple to deep. Since 2023, the automobile business map has accelerated. Under the background of the rapid development of smart car industry, Huawei is expected to rise with the advantages of core technology, ecology, brand and channels. It is suggested to pay attention to the cooperative car enterprises in Huawei’s automobile industry chain and the core manufacturers in related fields such as intelligent driving, intelligent cockpit, three-electric system and traditional parts.

　　HuaxinIt is also indicated that the M9 is fully ahead in terms of safety, maneuverability and intelligence, and it is expected to become a new generation of explosive models, which will drive the flexibility of supply chain enterprises. It is suggested to focus on supply chain investment opportunities.He also said that he is optimistic about Huawei’s automobile industry chain.

　　Guosheng recently pointed out that the M9 in the world is expected to become another explosion of Huawei’s intelligent selection system, and it continues to verify that Huawei’s intelligent selection and empowerment car companies bring high growth. Continue to be optimistic about Huawei’s smart car industry chain. Smart car is a subdivision track with clear competition pattern and excellent medium-term logic. Considering Huawei’s industry-leading effects in autonomous driving, intelligent cockpit and intelligent safety, Huawei’s cooperative ecology is expected to enhance its product strength in the environment of intensified competition in the whole machine factory, and companies related to the industrial chain are expected to benefit from the development dividend of domestic smart cars by relying on ecological advantages, forming a pre-paid card position. At the same time, it is necessary to pay attention to the industrial changes brought by technology leaders, and autonomous driving is expected to accelerate its landing, forming an overall opportunity for the industry.

　　Why is the balance insufficient?

　　After investigation, there were more than 490 pieces of information during the period from September 14, 2019 to October 26, 2019, all of which were "expenditures". The column of "transaction type" was mainly displayed as "quick" and "consumption", with the lowest amount in 1 yuan and the highest amount in 1000 yuan.

　　Where did the savings go?

　　Mr. Zeng said that although Ermei deleted all the transaction records in the short video software and the game, she inquired about Alipay payment records, of which about 50,000 yuan was used for "rewarding" and about 20,000 yuan was used for buying equipment in the game.

　　Why are you spending like crazy?

　　The girl told so-and-so that every recharge is voluntary and rewarding the anchor is voluntary. The reason for frequent recharge is: First, because it can be upgraded, there is pride in front of students who also play this game; Second, because you buy "skin" by recharging, you can have many beautiful clothes.

　　In order to upgrade the game and reward the anchor, a 13-year-old girl from Zigong, Sichuan, recharged a short video platform, "Fifth Personality" and "Mini World" in China for more than 490 times in 43 days, and stopped her "crazy games" … …

　　His mother, Wen Qingshu, said that this deposit of more than 70,000 yuan is the only savings saved by the family in the past two years. When this happened, she blamed herself, saying that she didn’t discipline her children well on weekdays. At the same time, she also hopes that the platform can be refunded.

　　On November 10th, Wen Qingshu reported to the local police station in Fushun, Zigong for help. A few days ago, the Chengdu Business Daily-Red Star journalist also contacted the short video platform involved, and the other party responded that if the minor rewards without the consent of the guardian, once verified, the platform will give a full refund.

　　Insufficient balance

　　Mother’s bank withdrew more than 70,000 yuan and her savings were "missing"

　　At 3 o’clock on the afternoon of November 10th, Wen Qingshu, 51, from Fushun County, Zigong City, went to the bank to withdraw money to pay the rent. The counter staff told her that "the balance of your card is insufficient", which surprised her: the card clearly has more than 70,000 yuan. How could it be missing?

　　Through further inquiry, it was found that the savings card was artificially bound to Alipay, and almost all of the 74,242.58 yuan in the card was spent through Alipay, leaving only 0.46 yuan.

　　Wen Qingshu and her husband have three daughters. The eldest daughter has worked, and the second and third daughters are still in primary school. For many years, her husband worked in other places, and Wen Qingshu spent most of her time at home taking care of her two daughters’ diet and daily life. Wen Qingshu’s education level is limited, and she has little contact with new things. She has never used online payment methods such as online banking, Alipay and WeChat. For the sake of economy, even the simplest bank card SMS prompt function has not been opened.

　　So, who moved the savings deposit at home? Wen Qingshu hurriedly called her eldest daughter and asked her to come back and find out.

　　Checklist

　　More than 490 expenditure records　Once at most, 1000 yuan.

　　Knowing that the money in her mother’s bank card was "missing", the eldest daughter called her husband to the lady and hurried back to Fushun from Zigong City. With the help of her daughter and son-in-law, Wen Qingshu printed the running list in the bank and then took it home to check it carefully.

　　After consulting, the running list information from September 14, 2019 to October 26, 2019 is really surprising.

　　According to the inventory records, there are about 508 pieces of transaction information in the whole year, among which only more than 10 pieces of transaction information were recorded from November 11, 2018 to September 7, 2019, while more than 490 pieces of information were recorded from September 14, 2019 to October 26, 2019, all of which were "expenditure", and the column of "transaction type" was mainly displayed as "quick" and "consumption".

　　After the transaction on October 26, 2019, Wen Qingshu’s bank card had no transaction record. Until the afternoon of November 10, she went to the bank to withdraw money and found that the balance in the card was only 0.46 yuan.

　　Through speculation and repeated thinking, the family included their second daughter Xiang Moumou as a suspect.

　　family meeting

　　The second daughter admitted spending Cary’s money.

　　Used to recharge games and reward anchors.

　　Mr. Zeng, the son-in-law, told the Chengdu Business Daily-Red Star journalist that at 6 pm on November 10th, a family meeting was held at home, and the second daughter admitted that she had moved her mother’s bank card.

　　The second daughter confessed to her family that the money in the bank card was used by her, but it was not clear how much she used, except that after the last payment at the end of October, she could no longer use it. These 490 expenses totaled more than 74,000 yuan, all of which were used for game recharge and rewarding anchors.

　　Under the family’s questioning, the second daughter also admitted that the money was mainly used in two aspects, one was to buy "skin" in the game, and the other was to "reward" the anchor when watching the live game in the short video software. Mr. Zeng said that although Ermei deleted all the transaction records in the short video software and the game, she inquired about the payment records of Alipay, of which about 50,000 yuan was used for "rewarding" and about 20,000 yuan was used for buying equipment in the game.

　　The reporter looked at the contents of the games played to XXX, mainly role-playing games. In one of the game interfaces named "Fifth Personality", the role information played by XXX shows that the recharge data is 156,490, and the recharge amount is 15,649 yuan (without deducting the gift score) according to the rule that 1 yuan money is exchanged for 10 points set in the game.

　　According to Mr. Zeng, most of the deposits in the bank card are used to "reward" many live anchors in short video software, and almost all of them play role-playing games live. According to his incomplete statistics, the amount used to reward someone is about 50,000 yuan.

　　The girl involved

　　Recharge and reward are voluntary.

　　For "pride" and "nice clothes"

　　The girl told the reporter that she probably started to contact role-playing games at the beginning of last year, mainly focusing on the game of "fifth personality". She plays with her mobile phone every day when she comes home from school. Under normal circumstances, she plays games for two or three hours every day, and on weekends, she spends more time.

　　In the game, you can upgrade to someone by "fighting", and at the same time, you can purchase points by recharging cash to achieve rapid upgrade and buy different types of "skins" in the mall. Judging from the running list, the first recharge time to XXX was September 14th, 2019, and the recharge amount was 1 yuan money, and then it was increased one after another until it was expanded to watch live video and reward live anchors.

　　Xiang said that the mobile phone number she used was registered with her mother’s ID card, and then she quietly found her mother’s bank card, and registered Alipay through self-study, and then began to recharge.

　　From 1 yuan to 10 yuan, to 68 yuan, and then to 198 yuan, the highest single recharge of 1000 yuan … … After trying again and again, I found that my mother would not find out after each recharge, so the amount of recharge was increasing. In her opinion, Cary’s money is inexhaustible.

　　To say that every recharge is voluntary, and rewarding the anchor is voluntary. The reason for frequent recharge is: First, because it can be upgraded, there is pride in front of students who also play this game; Second, because you buy "skin" by recharging, you can have many beautiful clothes.

　　For the reporter’s question "Do you know how many clothes you can buy with the money you recharged in reality", I said "I don’t know" to XXX; The reporter asked, "Do you know what the money is for your mother and family?" He also said, "I don’t know."

　　Mother blames herself.

　　It is also responsible for not disciplining your daughter well.

　　I hope the platform will refund.

　　Wen Qingshu, the mother, blamed herself very much. She said frankly, "I don’t understand these high technologies", but the fact that her second daughter spent all her savings playing games at home also blamed her for not disciplining her daughter well on weekdays and should bear part of the responsibility.

　　Wen Qingshu said that this 70,000 yuan was accumulated in the past two years, when her husband worked outside the home and saved money. So much money was saved at home, and she hoped to save more for her second daughter and third daughter to study. Suddenly, all my savings are gone, and I feel very sad. I don’t know what to do. I hope the platform can get a refund.

　　At 9 o’clock on the evening of November 10, Wen Qingshu, accompanied by her eldest daughter and son-in-law, went to the local police station to report the case. On November 11th, Mr. Zeng, the son-in-law, took his second sister to the local cultural department to reflect this situation, and called the cultural department where the relevant game software was registered to tell the story and put it on record.

　　Mr. Zeng told reporters that they hope more parents can take warning, correctly guide and manage their children to play games, and avoid similar situations from happening again. At the same time, they also want to seek help through the media to understand the legal ways to recover related losses, hoping to get a refund.

　　Platform involved

　　If the minor rewards without the consent of the guardian

　　Once verified, a full refund will be made.

　　A few days ago, the Chengdu Business Daily-Red Star journalist also contacted the short video software platform used by Xiang Moumou. According to the relevant person in charge of the platform, first of all, the platform does not approve of minors to recharge their rewards when watching live broadcasts. If minors reward without the consent of their guardians, once verified, the platform will refund them in full. In addition, when minors use the software platform, parents can first turn on the youth mode in the interface. After this mode is turned on, content suitable for teenagers will be presented, and it is impossible to recharge the live broadcast.

　　In addition, the relevant staff of the production platform of the "fifth personality" game said that in the event of similar situations, parents are advised to make corresponding complaints through the "caring platform" of the platform. In addition, the platform suggests that parents can communicate with their children more and educate minors to play games reasonably. The platform will also work with parents to jointly protect the growth of minors.

　　Lawyer’s statement

　　A 13-year-old girl is a person with limited capacity for civil conduct.

　　Can declare a refund to the operating platform.

　　But guardians are also at fault.

　　Lawyer Zhang Shouyao of Sichuan Fangce Law Firm believes that the General Principles of Civil Law stipulates that minors over the age of eight are persons with limited capacity for civil conduct, and they can perform civil legal acts on their behalf or with the consent and ratification of their legal representatives, but they can independently perform civil legal acts that are purely beneficial or that are suitable for their age and intelligence.

　　Zhang Shouyao said that as far as the incident is concerned, the 13-year-old girl recharged the game and rewarded more than 70,000 yuan, which is no longer a civil act commensurate with her age and intelligence. If the legal representative does not ratify it, the act is invalid and she can request to return all the recharge and rewards. On the one hand, it can be solved through negotiation, and if necessary, it can seek help from the Consumers Association; If negotiation fails, it can be settled through litigation.

　　Lawyer Feng Jun, a member of the Rights Protection Committee of Sichuan Lawyers Association, said that the 13-year-old girl is a minor and a person with limited capacity for civil conduct in civil law, and she can make judgments on life matters corresponding to her current age. It is generally understood that it is ok for girls to play games such as video game city if they spend hundreds of dollars to buy game coins, but it is invalid to use more than 70 thousand yuan for game recharge one after another. Based on this, the game operator should return the prepaid money to the girl’s parents "because the girl’s big recharge behavior has not been approved by her parents".

　　Feng Jun said that as parents, they should fix evidence to prove that their parents are unaware of the large recharge behavior, and then report to the customer service phone of the game operation platform. If the platform refuses to accept it, they can file a lawsuit in the name of their parents and recover the money through judicial procedures. In addition, Feng Jun also said that in this incident, the girl’s parents, as guardians, failed to fulfill their guardianship responsibilities and bank card custody responsibilities, and they also had certain faults.
