　　[car home Industry] When people talk about ZF, they must have a high evaluation of its 8AT gearbox. There are countless partners in this star product, especially BMW, which is famous for its control. Most of its models use ZF 8AT gearbox. Today, ZF will no longer be a simple gearbox company, but will gradually evolve into a technology company focusing on the future travel field.

　　"Before 2030, ZF’s contribution to the Asia-Pacific region needs to reach 30% of the group’s income, and the China market will become the main source of growth to achieve this goal." At the strategic cooperation ceremony between ZF and China technology company Tiantong Weishi on June 15th, Dr.Holger Klein, director of ZF Group, said, "This requires us to cooperate with forward-looking partners in the local ecosystem of China."

■Why did you choose Tianqi Weiwei?

　　On June 15th, ZF signed a strategic cooperation agreement with CalmCar to jointly develop cost-effective automatic parking (APA) and automatic parking service (AVP) systems. At the same time, this is the first time that ZF has invested in a local start-up technology company in China.

　　In Ke Haozhe’s view, it is now in an era full of challenges and changes. On the one hand, the travel industry is facing common challenges such as COVID-19 epidemic, chip trade and climate change; On the other hand, software-defined cars, as well as the development of technologies such as autonomous driving, artificial intelligence and 5G, will combine the digital world in the field of travel with the real world. These common challenges and opportunities are complex and interrelated, and ZF should cooperate with upstream suppliers, first-class suppliers and automobile manufacturers.

"Ke Haozhe, Director of ZF Group"

　　In recent years, by actively participating in the domestic ecological circle, ZF has actively deployed its work focus and company resources in the high-tech development of China, and taking a stake in Tiantong Weishi is a major move of ZF. "This year coincides with the 40th year of ZF’s operation in China. At this key node, ZF participates in the China automobile ecosystem and has deeper cooperation with China start-ups. This is also an important performance of the Group’s emphasis on the China market. " Ke Yuzhe said.

　　ZF has made some achievements in the key technical fields of automatic driving, from high-precision sensors and intelligent actuators to high-efficiency on-board central computers and service-oriented software systems. Perhaps the outside world will ask, start-ups are overwhelming, why did ZF choose Tianqi Weiwei?

　　Xing Xun, Engineering Director of China Electronics and Driver Assistance System Division of ZF Group, said, "As early as 2017, ZF cooperated with Tianzhu, and now the technical achievements of our cooperation have been verified in 3-4 years. This also means that this technology is reliable. "

　　"ZF is not willing to invest in a company if it is only famous, rather than the two sides spend time and energy on joint development. This is a starting point for ZF to cooperate with start-ups in China-it takes some time and technical precipitation. " Xing Xun added.

　　At the same time, Damon, founder and CEO of Tiantong Weishi, predicted that in 2023, L2-class and L3-class advanced assisted driving will achieve large-scale development in the China market, and in 2025, China will usher in large-scale mass production of L4-class autonomous driving. Compared with the global OEM layout, China will be two years ahead, among which low-speed assisted autonomous driving has completed 35% assembly rate in 2020.

　　ZF and Tiantong Weishi have come a long way, and now is the right time to strengthen and deepen cooperation.

Wang Runyi, President of ZF China and Senior Vice President of Asia Pacific Operations, and Damon, Founder and CEO of Tiantong Weishi.

■AVP system landed in China on a large scale?

　　"The automatic parking system, whether it is the end consumer or the OEM, has a very strong demand for this function." Asked why ZF laid out the AVP field, Xing Xun said, "Aiming at the problem of parking difficulty, automatic parking service is a product that really comes from the demand side."

　　ZF will start with automatic parking and automatic parking service, and build future-oriented autonomous driving technology to support the next generation of travel modes. If we look back at the Shanghai Auto Show in April this year, ZF released AVP automatic parking service technology for the first time. In fact, this technology is based on the deep cooperation between the two parties.

　　ZF’s specialty in sensor actuators and system integration, combined with the software support of Tiantong Weishi and the crowdsourcing map technology of another partner, this AVP automatic parking service technology can provide an economical and efficient solution for car companies without relying on the transformation of parking lot infrastructure and the prefabrication of high-precision maps of parking lots.

　　"Actually, ZF has a relatively comprehensive layout in L2-level assisted autonomous driving and L4-level autonomous driving on highways. Comparatively speaking, there are shortcomings in the low-speed automatic parking scene." Xing Xun said frankly, "In this field, the working conditions in China are very different from those in foreign countries, including the parking environment and garage construction methods. Cooperation with Tianzhu Weishi is essentially a supplement and improvement to ZF’s construction of autonomous driving map. "

　　Just as the technical route of self-driving cars is divided into bicycle intelligence and vehicle-road coordination, automatic parking service also has two major routes: vehicle end and field end. It is reported that the AVP system jointly developed by ZF and Tianzhu is mainly based on vehicle intelligence.

　　The automatic parking service system is equipped with four fisheye cameras with a panoramic view of 192. By using the fusion of 360 panoramic view perception of Tiantong Weishi and ultrasonic radar perception, the system can effectively identify parking spaces and obstacles, help vehicles locate indoors and outdoors, and plan automatic parking paths in real time.

　　"There are 400,000 paid parking lots in China. If we carry out large-scale field-side renovation, it is actually unrealistic. Therefore, Tianzhu Weishi uses its own unique algorithm advantages and combines ZF’s century-old experience to realize automatic parking service without increasing the cost of the vehicle on a large scale. " Damon, founder and CEO of Tianzhu Weishi, stressed, "Only in this way can the AVP system land quickly and on a large scale."

　　It is understood that ZF AVP system is scheduled to be installed for the first time on the models of China automobile manufacturers at the end of 2022, and the landing scenes are airports, shopping malls and parking lots.

■Meet the new challenges of China market

　　"The cooperation between ZF and Tiantong Weishi is a good start, but such cooperation is definitely not the only cooperation of ZF. We will conduct a very profound and comprehensive investigation in the future to find a partner that complements ZF in culture and technology in the automobile ecosystem, making the overall business model of the group more flexible." Wang Runyi said, "This is our goal, and ZF will carefully and openly choose China partners."

　　2021 is the 40th year that ZF entered China. In these 40 years, ZF has witnessed the rapid development of China automobile industry. From 1981, ZF received its first order in China, to 1994, ZF opened its first factory in Langfang, and now, ZF has nearly 50 manufacturing enterprises and three R&D centers in China. ZF has gone through the process from "sales in China" to "manufacturing in China" and then to "R&D in China".

　　It is worth mentioning that ZF’s sales in China increased by 10.3% in 2020, which is at the same level as that in its home market. In the past two years, as a Tier1 supplier, ZF found that the demand of China OEM changed greatly.

　　"First of all, the OEM’s own research and development capabilities have been significantly improved; Secondly, the technology and services provided by the main engine factory to suppliers need to be faster in response speed; Finally, it is more flexible in technical requirements, and tends to combine the specific needs of OEMs, with a more systematic and deeper understanding. " Wang Runyi told car home.

　　"In the past, a new model was developed for three or four years. This era no longer exists. What we see is the average aging of 6-18 months. This puts higher demands on ZF’s R&D team. " Wang Runyi believes that ZF needs the help of local start-ups in China to respond to customers’ requirements quickly.

　　In fact, at the technical level, the supply mode of black box or white box in the past can no longer meet the needs of OEMs. "OEMs hope that ZF can help tailor the architecture based on them and make technical synthesis according to customer needs." Wang Runyi said.

　　For example, the cooperation between ZF and Tiantong Weishi not only speeds up the R&D process of ZF localization, but also shortens the technology R&D cycle, accelerates the technology iteration speed, and enables the latest technology to be put into the market better and faster. By strengthening technical exchanges, the two sides will jointly build a new platform with complementary advantages and win-win cooperation.

　　As Wang Runyi said, "China is the top priority of ZF’s future development strategy. We will continue to increase investment in China, welcome the deepening exchanges between partners inside and outside the industry with an open mind, look forward to the future together, and explore different cooperation modes. Qi Xin will work together to turn challenges into opportunities, which will make it impossible and possible."

■ Editor’s summary:

　　In addition to the automatic parking service technology launched this time, ZF has continuously expanded its business boundaries in recent years, focusing on the "next generation travel" strategy. For example, the establishment of the electric drive technology division, the integration with the commercial vehicle technology company Webeco, the sales of independent software solutions and the establishment of a brand-new software center. There are no enterprises that are always successful, only enterprises that constantly adapt to the general trend of the times. (Text/car home Peng Fei)

Editor Bailu

Recently, Qi Song, the "assassin in the workplace" in "20 Don’t Confuse 2", made frequent comments on the Internet, and was evaluated by the audience as "everyone’s Internet mouth replacement".

　

Qi Song (Fei Qiming) is smart, creative, romantic and gentle, and warms the person he likes like a little sun, with 100% healing power!

At work, he is an anti-anxiety and anti-involution person.

　

When the project encounters problems, Qi Song will not keep working overtime to put pressure on himself like ordinary people, but will open up new ideas for himself by entertainment.

When the project was completed, but the leader stepped in to grab the work, Qi Song dared to resist the angry leader.

　

In feelings, he is a walking generator.

　

Qi Song and Xiao Guo (Guanjin Bu) look at each other in the power-off office. It’s hard not to be moved by this atmosphere!

Although on the surface, they always quarrel and play like chickens in primary school, in fact, Qi Song has a crush on Jiang Xiaoguo (Guanjin Bu) since high school. When I was in college, I went abroad for further study. After becoming more independent and excellent, I returned to Xiaoguo to provide her with energy.

　

Xiaoguo introduced his name as "small" and "fruit" of fruit.

Qi Song said that it was the other mountains all appear dwarfs under the sky.’s "small" and fruitful "fruit".

This is the so-called "beauty is in the eye of the beholder" ~

　

Xiao Guo’s speech after drinking for a long time was recorded by a willing heart and sent to the company group for "public punishment". Qi Song will immediately use the expression pack to screen the screen to ease her embarrassment.

　

When two people encounter difficulties in a cooperative project, he always tries his best to solve them and become the most solid back of Xiaoguo.

I can not only fight with her, but also struggle with her. When I get along, I am a happy maker. At the critical moment, I am the best partner who is calm and reliable. Please give me a dozen of this kind of boyfriends!

　

Qi Song’s anti-involution and anti-anxiety "workplace assassin" is rare in domestic workplace dramas, and his debut experience as a player, Fei Qiming, is like an "assassin" and unique in the entertainment industry.

　

In 2017, several ten-second videos made Fei Qiming, who was still in college, become the first generation of online celebrity in Tik Tok, and created a unique school grass style with gold-rimmed glasses and boyish smile. However, in the booming era of short videos, Fei Qiming has set his sights on the entertainment industry.

In 2018, Fei Qiming began to "de-online celebrity" and participated in the popular variety "Happy Camp". His popularity on the Internet remained high, and his road to transformation officially began.

　

In the same year, he received an invitation to audition for the school play "I am waiting for you in the future" and partnered with Qian Sun, Xin Yunlai and other new generation actors. In the play, he plays Liu Dazhi, an optimistic boy, who not only won the recognition of Li Guangjie, an old opera player, for his courage of being a newborn calf, but also reversed the questioning voice before the broadcast because of his natural performance and true feelings. This is the first step in his transformation from online celebrity to an actor.

　

But because I devoted myself to filming and didn’t update Tik Tok for a long time, I lost a big wave of fans. For the gains and losses, Fei Qiming is very calm: "I hope I can sink and be seen when I look up."

　

However, the popularity of a drama series didn’t make him completely get rid of the label of Tik Tok online celebrity. What really made Fei Qiming break through was various popular variety shows.

　

From his debut in 2018 to the present, Fei Qiming has won a total of 8 variety shows. Among them, Iqiyi’s parent-child reality show "Super Kindergarten", RV travel reality show "Flower Road of Youth", Tencent’s video beauty program "Prince Lipstick", and now the popular variety "Fifty Kilometers of Peach Blossom House" and other variety shows have his figure.

　

Now, he not only proved his talent and hard work in performance again in "Twenty Don’t Confuse 2", but also a large wave of dramas to be broadcast filled the audience’s expectations.

　

For example, the sci-fi drama Orphan of Mars, adapted from the novel of the same name by science fiction writer Liu Yang, in which Fei Qiming plays the man Guhe.

Although his debut is only four years, and there are only a handful of film and television works, Fei Qiming, who was born in online celebrity, is full of love for acting. When talking about the career of actors, he said that "actors only have a starting point and no end point; The sense of crisis as an actor is everywhere. "

　

There are many people who want to lose weight, but very few people can really reinvent themselves. Fei Qiming is one of them. At the age of 17, Fei Qiming was a little fat man weighing nearly 200 Jin. However, in a few years, he turned into a sunny male god on the university campus. After entering the entertainment industry, he set up a special area at home to study scripts and feel the lives of different roles in order to hone his acting skills.

In line with the image of "little sun in the workplace" on the screen, he is also a versatile big boy in reality.

Not only is he proficient in playing and singing, but he also writes well. A little brother who is handsome and can sing and act ~

From the figure counterattack to the transformation actor, his dedication perfectly explains that down-to-earth talents can accumulate thick hair. I believe that Fei Qiming in the future will make constant progress and realize his dream of "becoming a good actor".

1. Is the battery of electric vehicle a dry battery or a lithium battery?

Dry batteries are generally lead-acid batteries. With the same capacity and voltage, the weight of lead-acid battery is three times that of lithium battery. Lead-acid batteries also have a short life. Current lead-acid batteries can’t go far in two years, while lithium batteries can last for five years. Due to its own weight, the battery life is incomparable to that of lithium batteries. But dry batteries are cheaper. It depends on how you choose. What suits you is a good lithium battery electric car: advantages: high efficiency. The car body is light, the mileage is long, and the requirements for the use and maintenance of users are not strict. Disadvantages: the price is high, and the domestic lithium battery technology is uneven, and the lithium battery used for electric vehicles has potential safety hazards. Lead-acid battery electric vehicle: advantages: high cost performance. The battery is relatively cheap, with large capacity, many battery brands and mature technology. Disadvantages: the efficiency is not very high. The battery pack is bulky, resulting in a heavy body and short mileage, so it is necessary to maintain the battery regularly.

2. Is dry battery or lead-acid battery better for electric vehicles?

Electric bicycles and motorcycles have become important means of transportation in large, medium and small cities and are generally accepted by people. Compared with traditional bicycles, the price of electric bicycles is generally higher, so the service life has become the most concerned issue. In fact, the battery is one of the core components of the electric bicycle, and the service life of the battery largely determines the service life of the electric bicycle. In this regard, Chaowei Battery said that strengthening the maintenance of the battery will extend the service life of the battery. It is understood that the batteries used in electric vehicles are lead-acid batteries! Dry batteries are a scam! In addition, I will send you a message: the starting current of electric vehicles is very large, especially for electric motorcycles with high-power motors. Heavy current will damage the battery plate. The best way is to start the power supply after riding the electric car like riding a bicycle. After the battery is used for a period of time, some active substances will inevitably settle. If the active substance is not activated in time, it will definitely affect the capacity of the battery. Deep discharge the battery once. Judging from the current use of electric vehicle batteries, lead-acid batteries are mature in technology, cheap in price and stable in performance. The dry battery of electric vehicle is mainly lithium battery, which is twice as expensive as lead-acid battery, but its service life is longer than that of lead-acid battery, but with the increase of charging times, its service life will become shorter and shorter. For example, lead-acid batteries need to be replaced once a year, and lithium batteries can be replaced once every two years, but lead-acid batteries can be replaced once a year, and the cruising range of lithium batteries will be shortened in the second year, which will affect their use.Compare their respective prices, calculate the cost and your own usage, and see which is more cost-effective. I recommend lead-acid batteries. Dry batteries are easy to use, durable and small in size, but the price is a bit expensive. It is the future development. Lead-acid batteries will be out of stock. Use lead-acid batteries. The storage capacity is stronger. If you ride it every day, you’d better charge it every day. I know a lot of fake batteries, so it’s unnecessary, right?

3. Is lithium battery for electric vehicle really better than lead-acid battery?

Lead-acid batteries have the largest number. Lead-acid batteries are the cheapest and most commonly used. China is the largest producer of lead-acid batteries in the world. It contains less pollution components and has good recyclability. The disadvantage is that the specific volume is small. In other words, under the same capacity, the weight and volume of the battery are very large. At present, lead-acid batteries are basically developed from floating batteries. Floating battery is not suitable for fast charge and high current discharge. Although technicians have spent a lot of energy on effective improvement and can put it into practical use, its service life is still very long. Colloidal batteries belong to a development category of lead-acid batteries. The simplest method is to add gelling agent to sulfuric acid, so that sulfuric acid can be electrically liquefied into colloidal state. The battery with electro-hydraulic colloid state is usually called colloid battery. In a broad sense, the difference between colloidal battery and traditional lead-acid battery is not only that electro-hydraulic battery is changed into colloid. For example, non-condensed hydrocolloids belong to colloidal batteries in electrochemical classification structure and characteristics. Another example is that polymer materials are attached to the grid, commonly known as ceramic grid, which can also be regarded as the application characteristics of colloidal batteries. Recently, some laboratories have added targeted coupling agents to the polar plate formula, which greatly improved the reaction utilization rate of the polar plate active materials. According to unpublished data, its weight ratio can reach 70wh/kg. These are the current industrial practice and the application examples of colloidal batteries that will be industrialized soon. The difference between colloidal batteries and conventional lead-acid batteries is that from the initial understanding of electrolyte gelation to the study of electrochemical characteristics of electrolyte basic structure,Then to the application and promotion of grid and active materials. Its most important feature is to manufacture better batteries along the road of lead-acid battery industry for 150 years with relatively small industrial cost. Its discharge curve is flat and its inflection point is high, and its specific energy is 20 times larger than that of conventional lead-acid batteries. The battery of electric vehicle must choose lithium battery. Lead-acid batteries used in traditional electric vehicle batteries will produce a lot of pollution and lead vapor after being discarded. According to statistics, a batch of waste batteries of electric vehicles will pollute tens of thousands of tons of water. Lead is not easy to be excreted, and it can also cause diseases such as metabolism, reproduction and nerves. Once the lead content in the human body exceeds the standard, it will lead to mental decline, fetal malformation, and it is easy to induce malignant tumors in children and even lead to death. Compared with lead-acid batteries, lithium batteries have natural advantages in environmental protection. The materials used for lithium batteries do not contain harmful heavy metals such as cadmium, lead and mercury. In the process of production and use, lithium batteries do not produce any pollutants, which ensures human health. Solved the problems of water source and soil. In addition, lithium batteries also have the advantages of large specific energy, long cycle life, low self-discharge rate and no memory effect. The storage energy density of lithium batteries is high, which has reached 460-600wh/kg at present, which is about 6-7 times that of lead-acid batteries. The service life can reach more than 6 years, and the anode lithium iron phosphate battery can charge and discharge 1cdo. Can be used for 10,000 times; It has high power tolerance, and the Ferrous lithium phosphate lithium-ion battery used in electric vehicles can realize the charge and discharge capacity of 15-30c, which is convenient for high-intensity start acceleration;The self-discharge rate is extremely low, which is generally lower than 1% per month at present, less than 1/20 of that of Ni-MH battery; Lithium battery can completely meet the power requirements of electric vehicle batteries, and become an ideal product for electric vehicle applications because of its green and environmental protection characteristics. I hope it will help you.

4. Why are the batteries of electric vehicles all lead-acid batteries?

Of course not, because lead-acid batteries have the following characteristics and advantages: sealed structure, no acid leakage and no acid mist emission. One-way exhaust valve (also called safety valve), the function of this valve is that when the amount of gas inside the battery exceeds a certain value (usually expressed by air pressure value), that is, when the air pressure inside the battery rises to a certain value, the exhaust valve automatically opens, discharges gas, and then automatically closes the valve to prevent air from entering the battery. Compared with ordinary lead-acid batteries used in automobiles, valve-regulated lead-acid batteries have two main characteristics: one is sealing; The second is dry. Sealing means that there is basically no acid mist discharged. Generally, the VRLA battery is "zero emission" during its operation (charging and discharging), and only when the gas pressure in the battery exceeds the opening pressure of the safety valve in the later period of charging can a small amount of mixed gas of hydrogen and oxygen be discharged, and at this time, a small amount of acid mist is filtered out by a filter material. Dry state means that the VRLA battery has no free flowing electrolyte, and can be placed in any direction, not afraid of bumps and collisions, and no acid will leak out even if the shell is broken. During the use of lead-acid batteries, chemical energy is only continuously converted into electrical energy, and electrical energy is also converted into chemical energy, which is repeatedly circulated, thus causing "zero emission" to the external environment and no pollution to the environment, which you do not have with 40 No.5 batteries. 1. Electric vehicle batteries are not all lead-acid. Now there are many lithium-ion electric vehicle batteries, and most of them are composed of many small batteries. The adoption of lead-acid batteries is the result of many considerations such as production difficulty, cost and reliability.2. The basic feature of lead-acid battery is that it does not need to be maintained by adding acid and water during use. The battery has a sealed structure, which will not leak acid or discharge acid mist. The battery cover is equipped with a one-way exhaust valve (also called a safety valve), which is used to prevent air from entering the battery when the gas volume inside the battery exceeds a certain value (usually expressed by air pressure value), that is, when the air pressure inside the battery rises to a certain value, the exhaust valve will automatically open, exhaust gas and then automatically close the valve to prevent air from entering the battery. 3. Compared with ordinary lead-acid batteries used in automobiles, VRLA batteries have two main characteristics: one is sealing; The second is dry. 4. Sealing means basically no acid mist is discharged. Generally, the VRLA battery is "zero emission" during its operation (charging and discharging), and only when the gas pressure in the battery exceeds the opening pressure of the safety valve in the later period of charging can a small amount of mixed gas of hydrogen and oxygen be discharged, and at this time, a small amount of acid mist is filtered out by a filter material. 5. Dry state means that the VRLA battery has no free flowing electrolyte, and can be placed in any direction, without fear of bumps and collisions, and even if the shell is broken, there will be no acid leakage. 6. During the use of lead-acid batteries, chemical energy is only continuously converted into electrical energy, and electrical energy is also converted into chemical energy, which is "zero emission" to the external environment and will not cause pollution to the environment. One reason: cheap. If you change to a lithium battery, the battery will cost thousands ~ now it mainly depends on lead acid to store electricity and generate electricity, and there is no better material to replace it. Besides, this cost is low, which is suitable for the needs first! Not all batteries of electric vehicles are lead-acid.Now there are many lithium-ion electric vehicle batteries. Lithium-ion electric vehicle batteries. Most of them are also composed of many small batteries. The adoption of lead-acid batteries is the result of many considerations such as production difficulty, cost and reliability. Your scheme is feasible in theory, but just accumulating one item based on the quality difference between batteries makes your scheme useless. Not to mention cost and reliability.

5. What kinds of batteries are available for pure electric vehicles? There are two types of batteries for electric vehicles, storage batteries and fuel cells. Batteries are suitable for pure electric vehicles, including lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries, sodium-sulfur batteries, secondary lithium batteries and air batteries. Among them, lead-acid batteries, nickel-cadmium batteries and nickel-hydrogen batteries appeared earlier, and they are also the types of batteries that have been generally eliminated. Nowadays, the mainstream pure electric vehicles are basically lithium batteries, mainly including lithium cobalt oxide batteries, such as products; Lithium manganate batteries, such as (||) and Leaf Wind; Lithium iron phosphate batteries, such as products, (||), etc. Lead-acid battery is the most commonly used new energy vehicle battery. The polar plate of lead-acid battery is a grid made of lead alloy, the electrolyte is dilute sulfuric acid, and both polar plates are covered with lead sulfate. However, after charging, the lead sulfate on the electrode plate at the positive electrode is converted into lead dioxide, and the lead sulfate at the negative electrode is converted into metallic lead. When discharging, the chemical reaction in the opposite direction occurs. The advantage of lead-acid battery is that the electromotive force is stable when discharging, but the disadvantage is that the specific energy is small and it is corrosive to the environment. 1. There are two main types of batteries for electric vehicles, battery and fuel cell.

Among them, lead-acid batteries, nickel-cadmium batteries and nickel-hydrogen batteries appeared earlier, and they are also battery types that have been generally eliminated. Nowadays, the mainstream pure electric vehicles are basically lithium batteries, mainly including lithium cobalt batteries, such as Tesla products;Lithium manganate batteries, such as Toyota Prius and Nissan Leaf; Lithium iron phosphate batteries, such as BYD products, 1E, etc. 3. Lead-acid battery is the most commonly used battery for new energy vehicles. The polar plate of lead-acid battery is a grid made of lead alloy, the electrolyte is dilute sulfuric acid, and both polar plates are covered with lead sulfate. However, after charging, lead sulfate on the electrode plate at the positive electrode is converted into lead dioxide. 4. Lead sulfate at the negative electrode is converted into metallic lead. When discharging, the chemical reaction in the opposite direction occurs. The advantage of lead-acid battery is that the electromotive force is stable when discharging, but the disadvantage is that the specific energy is small and it is corrosive to the environment. For the time being, there are only experimental products for sodium-sulfur batteries for vehicles. 1. There are many kinds of fuel cells, such as hydrogen fuel cells, high-temperature fuel cells, direct methanol fuel cells, methanol reforming hydrogen fuel cells, metal fuel cells and so on. 2. At present, hydrogen fuel cells are the mainstream in the field of passenger cars, and Toyota is the representative factory. The biggest feature is that it can achieve pollution-free throughout the life cycle (from the beginning of raw material manufacturing to the final recycling). 3. The fuel hydrogen used has the characteristics of high energy density and zero pollution. The disadvantage is that the current cost is very high, and the volume power density is limited. Take the representative of the fuel cell vehicle (||) as an example, the volume of the fuel cell system of NO is roughly equivalent to a V6 engine, but the output power is only in the early 100KW, which is about 140 horsepower. The price of the whole vehicle is roughly equivalent to 338 horsepower. In fact, these two kinds of batteries can be said to have their own advantages. At present, lithium iron phosphate batteries are used a little more, because Ferrous lithium phosphate has good cycle stability.The cost is also relatively low. However, the consistency of Ferrous lithium phosphate is not as good as that of ternary battery, and there are still many problems in material stability, safety and processing technology. The specific landlord can check again, and the relevant information is still quite a lot. Personally, I recommend ternary batteries. At present, Ferrous lithium phosphate and ternary batteries are the main ones, and lithium manganate can be ignored. Take our car as an example. ev160 uses lithium iron phosphate battery, which is ternary lithium battery. Ferrous lithium phosphate’s technology is more perfect, but its future development is not as good as ternary lithium. I bought ev160, so I recommend Ferrous lithium phosphate, and I will buy ternary lithium car when ternary lithium technology is mature. Land Ark brought its newly listed pure electric vehicle v5s at the 2015 Energy Saving and New Energy Auto Show. The car was launched on October 15th, 2015, and it is the upgraded version of the first pure electric v5 launched by Land Ark in 2013. According to the staff, the car has a battery life of 150 kilometers and the price is about 75,000 yuan. Compared with lithium iron phosphate battery, ternary lithium battery has several improvements: power increase, energy density increase, charging rate increase, good low-temperature performance, and battery cells are combined and packaged. But lithium ternary is more unstable than Ferrous lithium phosphate, so the good and bad are 50% and 50% respectively.

    Observing two recent comedy films "Mr. Red Carpet" and YOLO, both veteran comedy director Ning Hao and rookie comedy director Jia Ling focus on portraying a hero who impresses the audience in their new works. This is not only an important guarantee for the quality of the two comedy films, but also shows us their respective characterization dilemmas, which is a very meaningful phenomenon. Taking this as an opportunity, we can start thinking about the future development of China comedy films.

    Mr. Red Carpet: How does absurd comedy create characters who can empathize with the audience?

    Starting from Crazy Stone in 2006, Ning Hao-style comedy has gradually become the most representative domestic comedy type after Feng’s comedy. Its basic formula is simply mature type+comedy+nobody. By learning from and mixing various mature types, its plot structure, characterization and artistic innovation ability are relatively strong. With the participation of small people, this comedy can produce works that are extremely suitable for social and cultural needs. It is precisely because of these advantages that Ning Hao-style comedy has led to the emergence of many excellent comedy films, which has contributed to the development of domestic comedy films in recent years.

    However, The Crazy Alien and The Beneficiary in 2019 marked some creative difficulties in Ning Hao-style comedies. The dilemma of Crazy Alien lies in Ning Hao’s desire to push his comedy creation to a new height, but it has raised the audience’s viewing threshold, and some songs are high and low. This made him have to face the confusion and confusion of whether to want art or box office. "The Beneficiary" reveals that there are also problems in the formula of Ning Hao-style comedy. First, there are mistakes and excesses in the borrowing and mixing of mature types; The bigger problem lies in the characterization, in which the little hero loses the real sense of life and is in danger of becoming an empty symbol.

    In the new director’s work "Second-hand Masterpiece" supported by Ning Hao in 2023, a new attempt of Ning Hao-style comedy can be observed, that is, the creation focus is completely on the characterization, and the work has successfully portrayed the image of the writer’s father. The creative thinking of "Mr. Red Carpet" is very similar to that of "Second-hand Masterpiece", and it still focuses on the characterization, which should be Ning Hao’s conscious pursuit of a breakthrough in comedy creation. Moreover, the portrayal of the hero in Mr. Red Carpet is still successful artistically.

    The characters are rarely three-dimensional and complex. In order to challenge and prove himself, Liu Weichi, the hero, started an adventure and showed his complex personality in this adventure. The film grasps the rhythm of plot development well, with both patient and meticulous plot preparation and plot climax. The appearance of one small incident after another pushes the protagonist to the corner of fate step by step and has to face the truth of his personality.

    Audio-visual expression is also very delicate. At the beginning of the film, an attitude towards the protagonist is established through a distant shot, that is, a critical presentation is made with a detached attitude. Many key scenes also show Ning Hao’s excellent audio-visual control ability. But he didn’t show off his skills, but served the characterization completely. The thinking reflected by the characters is more broad and layered. Some of these thoughts are related to the film itself: how to make a film in the era of short video and strong capital? What is the standard of art film? But there are also many thoughts beyond movies, which are related to our times and universal human nature.

    Regrettably, however, the audience did not buy this comedy film, which was so focused and successful in characterization. Among them, the biggest problem is that Ning Hao himself has fallen into a state of both necessary and important creation, which leads to the positioning error of the film. If it is positioned as an art film or an author film, this work can actually be explored more avant-garde in art. Because absurd comedy "is an exaggerated and profound serious comedy with philosophical connotation", on the one hand, it is highly intelligent and difficult to create, which puts forward higher requirements for the creator’s ability. On the other hand, it also means the possibility of innovation, which can help creators to explore the truth of life and the depth of human nature. If the creator’s ability is superior, it is possible to produce excellent works and classics. However, as a result, absurd comedy has a high threshold for viewing, and it is often difficult to become a high-box office movie because of the complexity and depth of thinking.

    Ning Hao’s twist is that he intended to put the film on the Spring Festival file before, which was originally for the box office. However, if we want to achieve high box office, we must make some improvements on absurd comedy. The previous Ning Hao comedies all had some absurd comedies, and an important magic weapon was to shape the image of a little person who was extremely close to the times and made the audience feel good. This makes Ning Hao-style comedies not only have a strong link with social reality, thus reducing the abstraction and despair of absurd comedies, but also enables the characters to form empathy with the audience. The box office success of Ning Hao-style comedies such as "Crazy Stone" and "Happy Flowers" depends on this.

    Mr. Red Carpet, on the other hand, is unwilling to make such improvement, but insists on its completely absurd characteristics and superior elite perspective. Not only is the content very abstract, but it also points the critical edge at everyone. The image of the hero is not only the spokesman of high social status, but also the symbol of abstract spirit, which not only makes the audience feel alienated and disgusted, but also can’t form empathy with the hero. So even if this comedy created a successful character, the audience still didn’t buy it.

    YOLO: How do the characters in autobiographical comedies surpass themselves after empathizing with the audience?

    The uniqueness of Jia Ling’s films is that she has been filming herself all the time. She has integrated her life experience into comedy creation and become a unique autobiographical comedy. This film content with her life experience also gave birth to a unique hero image in her comedies: sincere Jia Ling. This makes it particularly easy for the protagonist of her comedy movie to form empathy with the audience, which has become a weapon for her to win high box office. But this autobiographical comedy creation idea is very limited to commercial comedy:

    The first is the subject matter limit. Judging from Jia Ling’s two works, the first one can be completely original, but the second one can only be adapted from the existing one, because the autobiographical content is limited after all. However, the story and character logic carried by the adapted works will not only create tension with Jia Ling’s autobiographical pursuit, but also expose Jia Ling’s lack of ability as a new director. Love of a Hundred Dollars shows a story of a heroine who has lost hope in life and seeks the meaning of life again from boxing training. This state of life of bereavement and despair is obviously not suitable for comedy. This also leads to YOLO’s need to find new spiritual characteristics for the hostess in the adaptation, and it must also belong to Jia Ling’s own characteristics, so the protagonist in "Hot" is shaped as a flattering personality with Jia Ling’s personality characteristics.

    However, this change of the hero’s spiritual temperament must be supported by reasonable plots and characterization, which exposes the problems of Hot. In order to show the kindness of the heroine, the film portrays all the people around her as villains, and the changes of many characters are too abrupt and illogical. In fact, they are just tools to push the woman to boxing, and their role is to make her fall into a rebellious situation with high-density conflicts. The accumulation of punchline in the film has nothing to do with the main plot, and it is funny for fun. In order to make the audience agree with the female host’s flattering personality, the film even directly uses "two apples", "depending on the mood" and "two people can still hug each other like that. I thought that if you want to get a hug, you have to be kind to people! " Wait for the dialogue scene to output opinions straightforwardly. But in fact, the motivation connection between the female host’s flattering personality and boxing is still unconvincing. All these show that the first two-thirds of the film still has a lot of room for improvement in film quality. The main attraction of the film comes from the final climax, but it also comes from the shock brought by Jia Ling’s physical and mental changes to the audience. Many viewers even think that the final weight loss tidbits of the film are more shocking than the film itself.

    The second is the limit of self-consumption. Jia Ling in Hi, Mom formed empathy with the audience by virtue of her sincere and painful emotional ties with her mother. In YOLO, Jia Ling used the real change of the flesh to express a kind of strength and form empathy with the audience. The real weight change of gaining 40 pounds first and then losing 100 pounds has become the key to shaping the image of the heroine, which also brings the most important drama in the film. To gain 40 pounds first is to change the lovely image of Jia Ling’s fat figure in the eyes of the audience, so as to make the audience feel strange about her. Losing another 100 pounds will not only make Jia Ling’s body bring great visual impact to the audience, but also make Jia Ling’s body become an important carrier of tenacity, tenacity, self-discipline and self-confidence after successfully losing weight. However, this kind of self-consumption is limited to Jia Ling, both as a director and an actress, and it is difficult to continue. This also means that there is still great uncertainty about how to create a high-quality character image in Jia Ling’s next film.

    Where is the future of characterization in China’s comedy films? China’s comedy film creation has been relatively weak in recent years, and the lack of attention to characterization is one of the great reasons. Both Ning Hao and Jia Ling put their creative focus back on characterization, which has brought good enlightenment to China comedy films to get rid of the current creative dilemma. If we look at the characterization of the two works comprehensively, we can find a way out for the future characterization of China’s comedy films. Jia Ling’s success inspires the creators that creating comic characters that can make the audience empathize must be the basis and bottom line of commercial comedy. Ning Hao’s efforts show that empathy alone is not enough, and we need to work hard on the three-dimensional complexity of characterization, the synergy of plot and audio-visual, and the depth of characters. If we can focus on creating high-quality characters that make the audience empathize, there may be great hope for China comedy films to get out of the current bottleneck.

　　On the morning of the 2 nd, Ms. Lin, who lives in a community in Longchi Street, Liuhe District, Nanjing, went out early in the morning and found a teenager in school uniform squatting in the grass next to the unit building; When Ms. Lin came home at 5 o’clock in the evening, she still saw the child sitting there, with almost no change in posture. She called him and he ignored him. The abnormal behavior of the teenager worried Ms. Lin, and she called the police for help. The police arrived at the scene and learned that the teenager was a junior three student, and his uncle lived in this building. On that day, he stayed here in cut class for one day to play mobile games on his uncle’s WiFi, which made the mother who came to the scene angry with Ms. Yu.

　　The reporter’s investigation found that the popularity of smart phones and children becoming "mobile phone controllers" have become a common worry for many families. Yangzi Evening News All-Media Reporter Ren Guoyong Correspondent Lu Gongxuan

　　A crazy teenager.

　　Sit in the grass and rub my uncle’s wireless network to play games.

　　Cut class, a teenager, squatted down to numb his legs and feet one day.

　　"There is a big boy I don’t know downstairs who has been sitting in the grass all day. I don’t care if I call him. Come and have a look." At 5 o’clock in the evening on the 2 nd, Ms. Lin reported the police.

　　After receiving the police, the police of Longchi police station arrived at the scene to check that a teenager was sitting downstairs in a unit of the community. He sat under his schoolbag cushion and held his mobile phone intently.

　　"He has been sitting here in this posture. I saw him when I went out in the morning. I didn’t expect him to be here when I came back in the evening. I don’t know what happened. I called him and he ignored me." Ms. Lin said that she noticed that the child was also enthusiastic and worried about what bad things would happen to him.

　　The policeman walked next to the teenager, and he was still absorbed in playing with his mobile phone, unaware that the policeman was approaching. The policeman patted him on the shoulder, and the boy suddenly got up, but he almost fell down because of numbness in his legs and feet. "What are you doing here?" In the face of the police’s question, the child bowed his head and did not answer, only saying that he had something to do.

　　After repeated inquiries by the police, he said that his surname was Cao, and he was in the third grade of a nearby middle school. His uncle lived in this building, and he squatted here to play games on the Internet with his uncle’s WiFi. "I didn’t do anything bad, I just wanted to surf the Internet." He said.

　　Subsequently, the police contacted Cao’s mother. Cao’s mother was surprised when she received the phone call, saying that she didn’t expect her son to go to cut class to play games, and spent a day squatting downstairs in her brother’s house for surfing the Internet.

　　Soon, Cao’s mother rushed to the scene angrily, and immediately scolded him for being unprincipled again and again in order to surf the Internet. Cao’s mother said that her son secretly bought a mobile phone with a birthday red envelope given to him by his elders a month ago. After the parents found out, they criticized him and advised him to return the mobile phone, which was awkward. Later, the parents confiscated the mobile phone, but I didn’t expect him to take it away from his family and come here to play. "He must know that my brother went out these days before he came here to surf the internet. The senior high school entrance examination is coming soon, and he is still so confused."

　　The police also persuaded and educated Cao, and Cao said that he would make up his mind to quit playing mobile phone addiction and prepare for the exam carefully. The police also reminded Cao’s mother to communicate with her children more often, divert his attention from playing mobile phones, and persuade her in time if she has bad habits. After the exchange between the two sides, Cao followed his mother home.

　　Parents’ troubles

　　Smashed the phone, and both girls cried sadly.

　　Do you want to buy it for your daughter now? Mom is very entangled.

　　"I want to use regret to describe my current mood. Now I am in a dilemma!" Ms. Zhang from Laifeng Community in Nanjing told the Yangzi Evening News reporter that her daughter had bought a children’s mobile phone in order to facilitate contact, and she could only answer the phone.

　　But later, my daughter always said that all her classmates used smart phones, and they used smart phones to check their study materials online. Ms. Zhang was hesitant at first. After discussing with her husband, she felt that the times were developing and her daughter’s ideas were reasonable. It might be helpful to use smart phones to access information. Later, I bought my daughter a smart machine with a price of more than 1,000 yuan. After using the smart phone, my daughter quickly played on WeChat and Weibo.

　　"We think there is nothing wrong with sending WeChat Weibo, but now the situation is getting worse and worse." Ms. Zhang said that her daughter’s grades plummeted and the teacher even found her playing mobile phones in class.

　　After discovering the problem, Ms. Zhang began to control her daughter to use her mobile phone. But when my daughter does her homework, she asks her for a mobile phone to consult the information from time to time, but sometimes she finds that she is using QQ or WeChat.

　　Ms. Zhang asked her daughter how to chat? The daughter’s answer is to exchange learning problems with her classmates. In this way, the daughter’s learning efficiency is getting lower and lower. Not long ago, I found my daughter playing small games until the early hours of the morning, and there were novels in the trace of mobile phone search. I clicked and found that my daughter was reading a "messy" article. In this way, the mother and daughter quarreled many times for the mobile phone, and in the end, she smashed the mobile phone.

　　"I smashed my daughter’s mobile phone, and both girls cried. She ignored me for two weeks, and I was heartbroken." Ms. Zhang said that recently, her daughter repeatedly assured her to study hard, proposed to buy a mobile phone again and promised to use it only for consulting materials and communicating with classmates. "I am very entangled, I am afraid to buy it for her, and she can’t control it." Ms. Zhang said.

　　Online small survey

　　Children are forbidden to use smart phones? Not all are objections.

　　In two examples, children have become "mobile phone controllers", which annoys parents. So, at the moment when smart phones are so popular, should children use smart phones? The reporter made a small survey through his circle of friends.

　　Should primary and secondary school students use smart phones?

　　The online survey lasted for one hour, and 51 people voted.

　　A: About 84% are against it.

　　Some parents who indicate the reasons think that underage students are addicted to their opponents’ opportunities, which are difficult to control, and most of them are used for entertainment.

　　B There is one case in which the parents fully agree with the opinion.

　　This parent believes that smart phones are the general trend, otherwise they will be out of touch with society.

　　C about 14% supported by conditions.

　　This part of parents believe that children need to attach conditions to the use of smart phones. If they want to use them, they must know what their children’s purpose is, and it is ok to check the study materials.

　　Teacher’s opinion

　　Every time a parent-teacher meeting is held, many parents complain to the teacher. Children can’t live without mobile phones all day. Should they use them? How can I quit cell phone addiction? Jiang bo, a senior teacher and grade leader of a senior middle school in Nanjing, said — —

　　Even using a mobile phone to check information has great disadvantages.

　　Jiang bo thinks that the only advantage for students to use smart phones is that they are easy to contact.

　　"Access to information is a cover. I found that the questions and answers of some so-called learning software are copied from each other, and there are many mistakes and typos. Students who are used to finding answers online lose the ability to think independently. I strongly appeal to students from primary school to high school to stay away from smartphones." Teacher jiang bo thinks that students who are used to finding answers through the Internet will have a decline in their habit and ability to use reference books, and their learning efficiency is very poor. Usually, they click on a window and another one pops up on the Internet. Students are so curious that they can’t control their reading that they can’t concentrate on completing their homework. Indulging in mobile phones is not good for health, typically, the eyesight drops, and you can only see farther if you look up. Holding mobile phones all day long causes some students to have poor face-to-face communication skills; Some parents are afraid that their children will be out of touch with society without using smart phones. This kind of worry is unnecessary. Mobile phones, like computers, can be learned as soon as they are learned, and there is no need to hold them every day. The mobile phone network has a search function, so it is difficult for parents to monitor whether the content they read is healthy or not.

　　Parents should set a good example for children to quit cell phone addiction.

　　How to quit cell phone addiction? Teacher jiang bo said that depending on the situation, some parents are strong and radical. If they don’t agree to their children’s demands, they will not agree, confiscate their mobile phones and shut down the Internet. Some students have problems in their early education, and their parents have not established an authoritative image at home, and they can’t do the three chapters of the contract. Even if their mobile phones are confiscated and the network is cut off, the effect is not good. Some parents can’t stand the soft grinding and hard foam, but still return their mobile phones to them. When the mobile phone is smashed and the network is closed, it will stimulate such children’s rebellious psychology and stronger curiosity about smart phones. A better way is for parents not to hang their heads all day playing with their mobile phones, but to turn off the home network skillfully, such as changing passwords, limiting traffic, limiting phone bills, and reading famous books on paper. Let children know that mobile phones are just tools and toys, and do not deny that mobile phones are getting more and more fun, but there are more exciting things in life. Parents should take their children to participate in colorful outdoor activities on rest days to divert their attention from mobile phones.

　　● Children’s voice

　　Hungry for respect, disgusted parents smash mobile phones.

　　Yangzi Evening News reporter also communicated with some middle school students. Some students also admitted that mobile phones are basically used for entertainment except making phone calls and finding answers. Sometimes parents will get angry with them after playing for an hour or two.

　　"I am more disgusted with my parents’ tough tone, and it is even more unacceptable to smash my mobile phone." Liu Tong Jr. said that sometimes it was late at night when he was playing with his mobile phone, and he knew that it was not good for him, but the momentum of his father rushing in made people sad.

　　Liu Tongxue Jr. said that even if he made a mistake, he hoped parents could communicate in an equal tone. "Confiscation when you come in is disrespect and distrust," Xiao Liu told reporters.

　　The teacher’s truth is in place, and the child’s voice should also be heard. But have you noticed that children are actually concerned about the same problem at a different level from us adults? They are more concerned about the attitude of parents when dealing with the use of mobile phones than whether they use the mobile phones themselves.

　　Therefore, we want to remind parents that every child has his own personality characteristics, and parents should consider their children’s situation comprehensively, find a communication method suitable for them, and handle this "mobile phone problem" well.

　　Hello, everyone, the busy day will be over again. We have compiled the highlights of the day for you in the evening paper for your quick review.
