According to the data released by the Centers for Disease Control and Prevention (CDC) on June 7, local time, as of June 7, local time, only 13 states in the United States had reached the goal set by Biden’s government, that is, 70% of American adults were vaccinated with at least one dose of COVID-19 vaccine before July 4. Data show that at present, more than 171 million Americans (accounting for 51.6% of the total population of the United States) have received at least one dose of COVID-19 vaccine, and nearly 140 million Americans (accounting for 42.1% of the total population of the United States) have completed two doses of vaccination.

　　Nearly half of the people aged 12 and above who meet the vaccination conditions have been vaccinated. However, the current vaccination rate has started to slow down. In the past week, an average of about 560,000 people in the United States were vaccinated every day, and the highest number of people vaccinated in a single day reached about 4.3 million on April 1. In the report, CNN pointed out that under such circumstances, it may be difficult for the United States to complete the Biden administration’s vaccination target on July 4. (CCTV reporter Xu Wei)

　　【PConline talk】 Since the popularity of smart phones, their endurance performance has become the main factor for everyone’s criticism. Although the current mobile phone has a large battery of three or four thousand mAh, it still cannot escape the situation of heavy users rushing every two days or even every day. At present, limited by the development of electrode materials/structures, the energy density of lithium batteries cannot be increased indefinitely. Therefore, charging has become an essential part of our daily life. So what is the knowledge of charging mobile phones? Today, the author talks to you about "how to charge correctly and safely."

Brief introduction of charging principle of mobile phone lithium battery

　　Charge first①In the constant current stage, the actual battery voltage is lower than the charging voltage (mostly 4.3v), and the battery voltage rises during the constant current charging process. When it rises to about 4.3v (the battery charge is about 85%), it enters.②Constant voltage mode, charging current gradually decreases, charging is about to be completed, and then enter.③Trickle charging mode, charging with pulse current, extending battery life.

　　Let’s start with a charging process diagram of mobile phone charging (lithium battery):

Battery charging curve

　　It doesn’t matter if you don’t understand the above one. In fact, in simple terms,The whole charging process of smart phone can be divided into three parts.：

　　①Constant current stage, when the actual battery voltage is lower than the charging voltage. The battery voltage (red solid line in the figure) gradually rises from a low value to a fixed value, but the current (blue solid line in the figure) remains unchanged. This is the constant current process of lithium battery charging.

　　②In the constant voltage stage, after the battery voltage reaches a fixed value, the current output to the battery gradually decreases, and the charging efficiency also begins to decrease. And this process is a constant pressure process.

　　③Trickle charging mode, finally, when it is close to full, enter the trickle charging mode and charge with pulse current until it is completely full, and the battery charging is completed.

Have you tried all these wrong charging methods?

　　1. Buy a new machine and charge it for 12 hours to "activate" the battery.

　　Many friends around me like to charge their new mobile phones for 12 hours, saying that this will activate the battery. In fact, the activation of lithium battery is not so troublesome. After long-term storage, lithium battery will indeed enter a "dormant" state, and its capacity is lower than normal. At this time, it only needs to be charged normally for 3~5 times (without deliberately charging/discharging) to activate the lithium battery and restore it to its normal capacity.

　　So you don’t need to drain the battery and charge it continuously for 12 hours when you buy a new machine.

　　2. Plug in the charger and play with your mobile phone while charging.

　　We often hear in the news that someone’s mobile phone explodes or gets an electric shock while charging. The final investigation results show that most of them are caused by shanzhai chargers, so if you need to buy a non-original charger, you must buy a product that has passed the national 3C certification, and the input/output parameters are correct, and the manufacturer information is available.

　　Simply put, when choosing a charger, you need to pay special attention to the following situations:

— — （1）.The input voltage is preferably a broadband voltage, that is, 100~220v/50~60Hz.In some areas, the charging head only has 110v input. If you take it back to China, you can burn the charger directly, or burn the mobile phone!

— —（2）.The output voltage is about 5v (4.9/5.1), and the larger the output current, the better (if it is too small, the charger often heats up at full load and the output is unstable), but if one end of the wire is a microUSB port, it will basically not exceed 3a, and the Type-C port may have more than 3 A.The amperage here only represents the allowable output current, not the real output current.

— —（3）.National 3C certification is a must.

— —（4）.Manufacturer information must be available.

— —（5）.The work of the cottage charger is rough (especially the beard insertion and the sealing edge of the shell) and the font is fuzzy, which must be distinguished.

— —（6）.Mobile phones that support fast charging are not recommended to use too thin wires for charging. VOOC flash charging can only use original wires, and QC fast charging wires must ensure the integrity of D+/D- lines (that is, connecting computers can identify devices).

　　In addition, we should not play while charging. After all, when charging, the battery and charging related circuits will emit a lot of heat. If the Soc of the mobile phone runs at high load, the body temperature will be too high. The mobile phone with too high temperature will also control the heat by reducing the performance and charging speed, which will lead to the slow charging experience.

　　3. Charge only when there is no electricity, and it will be full as soon as it is charged.

　　Don’t wait until the battery of your mobile phone is completely exhausted, and there is no need to fully charge the battery every time.Most of the current mobile phones are lithium batteries, and the emphasis is on "eating less and eating more meals". The life of lithium battery is measured by the charging cycle, not the charging times as everyone thinks. The charging cycle refers to the process that all the battery charges from full to empty, and then from empty to full. If there is a 2000 mA battery, you will be fully charged after every 200 mA, then you have to charge it 10 times to calculate a charging cycle (2000 mA =200mAh times 10 times).

　　The lithium battery that the mobile phone is now equipped with has no so-called memory effect. There is no need to worry about the impact of insufficient charging on battery life.Fill it if you want, and pull it out if you want.

　　4. When charging, the fever is obvious. Still wearing a mobile phone case.

　　Nowadays, almost everyone on a smart phone will give him a gorgeous "coat". I don’t know that lithium batteries will be hot when charging. These gorgeous "coats" will hinder the heat dissipation when charging the mobile phone, thus affecting the charging speed and even accidents.

　　If the user finds that his mobile phone is not obviously hot when charging, there is no need to take off the mobile phone case. If the mobile phone is hot when charging, he will take it off decisively.

Tip: How to charge quickly?

　　1. Shutdown charging/flight mode charging

　　　Many people know that the screen and processor are the most power-consuming places of mobile phones, but in fact, the RF module of mobile phones also consumes a lot of power, that is, even if you turn off the screen, if the mobile phone is still synchronizing data (for example, WeChat is still receiving messages), then your charging speed will not be fast.

　　So, when needed,urgentWhen charging, turning off the power of the mobile phone is the fastest charging method. In addition, we can also switch the mobile phone to flight mode, cut off the synchronization of data and improve the charging efficiency.

　　2. Make the phone cooler

　　In addition, too high/too low temperature will also affect the charging efficiency of lithium batteries. Apple said that the iPhone has the highest charging efficiency at room temperature of 22℃.

　　Android phones also use lithium-ion batteries or lithium-ion polymer batteries, so the appropriate charging room temperature should be close to iPhone. Therefore, avoiding too high or too low temperature during charging is also a way to improve the charging efficiency of mobile phones.

　　3. Avoid using computer USB port to charge.

　　When choosing a charger, many people will plug their mobile phones into the USB port of the computer conveniently, but the current output from the USB port of the computer is usually less than 1a(USB 2.0 500mA, 3.0 900mA). Therefore, it is recommended to use an independent power adapter, and the output current of the power adapter (charger) is suitable to be larger, so that the charger can output more current when the mobile phone has greater charging power demand, and it also avoids the unstable output caused by the long-term high-load operation of the charger (the one with small output current).

How to store the lithium battery of mobile phone?

　　1. Occasionally fully charge and discharge, and reserve a certain amount of electricity.

　　Although there is no memory effect in lithium batteries, there is no need for deep charging and discharging every time, lithium batteries, like other batteries, will have an "inert effect". If the chemicals in the batteries often do not participate in the reaction (that is, they are often not fully charged), they will also lose a certain capacity. Therefore, if the mobile phone is not used for a long time, it needs to be fully charged/discharged occasionally (once every 3 months or so), while lithium battery storage should avoid full charge/zero charge, and it is best to have about 40% power.

　　2. Avoid high temperature storage and physical impact.

　　Mobile phone lithium batteries that have not been used for a long time should be placed in a cool place to avoid electrostatic fire caused by being too dry, and should not be placed in a place that is too humid, because temperature and humidity will make lithium batteries self-discharge. The recommended ambient temperature for storage is 0℃~20℃. In addition, metal hard objects should be avoided to be stored together with lithium batteries, because the shell of lithium batteries is more likely to be pierced by hard objects and damage the batteries.

Summary: mobile phone charging can be done at will without entanglement.

　　Although there are many tips for charging mobile phones, and the knowledge about lithium batteries is not only those in the article, for ordinary mobile phone users,Pay more attention when choosing a charger and pay attention to the fever of the mobile phone when charging, which can basically ensure the battery life and safety.Besides, smart phones are getting cheaper and cheaper now, and many people have changed their phones before the batteries break down, so why do we have to worry so much?

　　June 25th is the National Land Day, and this year’s theme is "saving intensive land and strictly observing the red line of cultivated land".

　　Cultivated land is the most precious resource in China. General Secretary of the Supreme Leader pointed out that cultivated land is the lifeblood of grain production and the foundation of the sustainable development of the Chinese nation.

　　China has raised nearly one-fifth of the world’s population with 9% of the world’s arable land and 6% of fresh water resources. The basic national conditions of our country, with a large population and a small land, determine that we must protect the cultivated land which is important for more than one billion people to eat, and there must be no mistakes.

　　How to protect cultivated land?

　　"The requirements for the protection of cultivated land should be very clear. 1.8 billion mu of cultivated land must be deserved. Farmland is farmland and must be fertile land." At the The Politburo Standing Committee (PSC) Conference held at the end of 2021, General Secretary of the Supreme Leader expounded the core requirements of cultivated land protection from three dimensions: quantity, quality and use — — Strictly observe the red line of 1.8 billion mu of cultivated land, turn the existing cultivated land into fertile land, curb "non-agricultural", prevent "non-grain" and ensure "fertile land for grain use".

　　Every inch of land is related to the national economy, and a ridge and an acre carry people’s livelihood. Protect cultivated land and improve the quality of cultivated land, and our rice bowls will be stable, firm and good.

　　"Take ‘ Long teeth ’ Hard measures "

　　To protect cultivated land, we must first ensure the quantity.

　　As early as the Central Rural Work Conference in 2013, the General Secretary of the Supreme Leader emphasized: "Stick to the red line of 1.8 billion mu of cultivated land, and everyone has made a military order, which must be done. There is no room for bargaining!"

　　Everything is born in the soil. If the land does not exist, how will the food be attached?

　　Data from relevant departments show that China’s population of more than 1.4 billion consumes 700,000 tons of grain, 98,000 tons of oil, 1.92 million tons of vegetables and 230,000 tons of meat every day.

　　To meet such a huge consumer demand, the cultivated land must be kept at 1.8 billion mu, which is the bottom line that can’t be lower.

　　"Protect cultivated land like a giant panda" and "Take ‘ Long teeth ’ Hard measures "… Since the 18th National Congress of the Communist Party of China, the General Secretary of the Supreme Leader has repeatedly given important instructions on the protection of cultivated land.

On June 14th, 2023, in Linzi Town, Linyi County, Shandong Province, the combine harvester was harvesting wheat.

　　At the National People’s Congress this year, General Secretary of the Supreme Leader warned when attending the deliberation of the Jiangsu delegation: "The red line of cultivated land is investigated for life, and it must be investigated after retirement. This is all ‘ The great man of the country ’ 。”

　　Over the years, the legal system related to farmland protection in China has been continuously improved, and the bottom line of food security has been firmly established — —

　　The Land Management Law and the Regulations on the Implementation of the Land Management Law have been revised and implemented successively, and the Law on the Protection of Black Land came into being. The target of farmland protection was strictly assessed and the responsibility was compacted at different levels, and the systems of "balance between import and export" and "balance between occupation and compensation" were constantly consolidated. The "field-length system" put the responsibility of each field on people, and the protection target and task of 1.865 billion mu of cultivated land and 1.546 billion mu of permanent basic farmland clearly required to remain unchanged until 2035.

　　As of April 16 this year, the cultivated land area in China reached 1.914 billion mu, achieving a net increase in the total cultivated land for two consecutive years.

　　"Farmland is farmland"

　　"No one will be allowed to be flexible or tamper with the protection of cultivated land, ‘ Tian Xin doesn’t hurt ’ 。” When it comes to farmland protection, the Supreme Leader General Secretary earnestly warned.

　　In recent years, with the development of industrialization and urbanization, cultivated land is facing a series of challenges.

　　"Over the years, I have been cleaning up and renovating greenhouses, illegally building villas, building houses by occupying cultivated land indiscriminately and curbing cultivated land ‘ Non-agriculturalization ’ , prevent ‘ Non-food ’ When the request was made, the relevant departments played a combination boxing. " On December 28th, 2020, General Secretary of the Supreme Leader exhorted all provinces, autonomous regions and municipalities at the Central Rural Work Conference, "Land should be used for building cities, engaging in industry and protecting ecology, and it must be carefully calculated and prioritized, and it is absolutely forbidden to occupy cultivated land and engage in afforestation and greening in violation of natural laws."

　　In April this year, the Ministry of Natural Resources notified 67 inspectors of cultivated land protection to find major typical problems of violating laws and regulations. On the notification list, there are many cities and counties in the main producing areas.

　　Since the State Council issued a document in 2020 to resolutely stop the "non-agricultural" and prevent the "non-grain" of cultivated land, the illegal occupation of cultivated land has been curbed to some extent, but this phenomenon still exists. The existence of problems reflects ideological deviation, loopholes in responsibility and lax management, which also urges the provinces in the main producing areas to include the issue of cultivated land protection in the "list of problems" of theme education.

　　"Cuncha village change! Check inch by inch, change village by village! " In Shangqiu, Henan Province, a special campaign to control all kinds of illegal occupation of cultivated land is under way. This year, Henan has rectified 145,000 mu of cultivated land occupied by various illegal activities since 2019, with a rectification rate of 90.08%.

　　On June 14th, Jiangxi Province and the Eighth Steering Group of the Central Theme Education jointly held a special rectification meeting on outstanding issues in the field of cultivated land protection and a forum for soliciting opinions on "Several Opinions on Strengthening Cultivated Land Protection" to further promote the rectification of problems.

　　In view of 13 major grain-producing provinces and 5 provinces with large cultivated land, the Ministry of Natural Resources will carry out two sub-meter remote sensing image monitoring on the full coverage of cultivated land this year.

On September 2, 2022, the rice field painting in the 10,000-mu rice science and technology demonstration park in Fujin City, Heilongjiang Province.

　　Cultivated land, as a strategic and basic resource related to the national economy and people’s livelihood, is different from other resources and cannot be treated as a general commodity, let alone simply measured by economic value.

　　At the Central Economic Work Conference held at the end of 2021, the General Secretary of the Supreme Leader profoundly pointed out: "In some places, a lot of fertile land does not grow food, or farms are built, or flowers and fruits are planted. What about food?"

　　Stabilizing grain planting area is the premise of ensuring food security. To this end, in 2022, the No.1 Document of the Central Committee proposed that "cultivated land is mainly used for the production of grain, cotton, oil, sugar, vegetables and other agricultural products and forage". This fully reflects the central government’s firm will to control the use of cultivated land and the principle of proceeding from reality, and retains the resilience of the policy.

　　"Farmland must be fertile land"

　　To protect cultivated land, we should not only ensure quantity, but also improve quality.

　　"Building high-standard farmland is an important starting point. We must unswervingly grasp it, improve the construction standards and quality, and truly realize drought and flood protection and high and stable yield." "Farmland must be fertile land. It is necessary to build a national food security industrial belt, strengthen farmland water conservancy construction, implement black land protection projects, classify and transform saline-alkali land, and strive to build 1 billion mu of high-standard farmland." The General Secretary of the Supreme Leader made a clear request.

　　The Party’s Report to the 20th CPC National Congress proposed that "all permanent basic farmland should be gradually built into high-standard farmland".

　　On May 11th this year, General Secretary of the Supreme Leader came to Cangzhou City, Hebei Province, and inspected the dry and alkaline wheat fields in Xianzhuang District, an old town in Huanghua City, to learn about the saline-alkali land improvement, the cultivation, promotion and industrialization of dry and alkaline wheat. He pointed out that it is necessary to base on the fact that there are many saline-alkali land and great development potential in China, give play to the key role of scientific and technological innovation, intensify the transformation and upgrading of saline-alkali land, strengthen the development and popularization of crop varieties suitable for saline-alkali land, effectively expand the planting area of suitable crops, actively develop deep processing, and do a good job in the characteristic agriculture of saline-alkali land.

　　Insist on paying equal attention to protection and development, popularize the improvement technology of saline-alkali land, and expand the breeding area of drought-alkali wheat … … Today, Cangzhou is gradually building a regional agricultural production system and scientific and technological support system that adapts to the characteristics of saline-alkali land.

On June 15, 2023, in graphite village, Zhongdu Town, Luzhai County, Liuzhou City, Guangxi Province, villagers harvested beans in high-standard farmland.

　　The Central Committee of the Communist Party of China insists on the concept of system, and puts forward the idea of storing grain in the land and technology with overall vision and strategic thinking. Its core essence lies in cherishing resources and relying on science and technology to take the road of connotative development.

　　Consolidate the foundation of cultivated land and make it better. As of April 16th this year, the Ministry of Natural Resources has incorporated cultivated land into the integrated protection and systematic management of mountains, rivers, forests, fields, lakes, grass and sand in the comprehensive land improvement work, and has established 446 pilot projects in 28 provinces, autonomous regions and municipalities across the country with townships as the basic implementation unit.

　　Consolidate the foundation of cultivated land and let fertile land achieve high-quality development. By the end of 2022, a total of 1 billion mu of high-standard farmland will be built nationwide, ensuring a stable grain production capacity of more than 1 trillion Jin. This year, we will continue to strengthen the construction of high-standard farmland, build 45 million mu and upgrade 35 million mu, creating more favorable conditions for consolidating the foundation of food security in all directions and accelerating the construction of an agricultural power.

　　Today’s arable land is tomorrow’s rice bowl, farmland is farmland, and it must be fertile land.

　　As General Secretary of the Supreme Leader said when he was in the delegation of the two sessions last year, "A big country like us must absolutely rely on itself." "We must have a bottom-line thinking and never forget the danger. Born in sorrow, died in happiness. "

　　On the new journey, we should protect cultivated land like giant pandas, so that every inch of land can become fertile ground for harvest.

A few days ago, the online auto market obtained a set of preview pictures of Mercedes-Benz’s new generation GLC. The new car will be officially released in overseas markets on June 1, and it is expected to be the first to be listed and sold in overseas markets before the end of this year. At the same time, Mercedes-Benz’s new GLC domestic models are also expected to be released one after another before the end of this year, when its product strength will also be greatly improved, and it will continue to compete with BMW X3, Audi Q5L, Cadillac XT5 and other peers.

It is reported that Mercedes-Benz’s new generation of GLC power will continue to be equipped with a 2.0T low-power turbocharged engine, the transmission system will match the 9-speed automatic manual transmission, and a four-wheel drive system will be provided, and a 48-volt light mixing system will be added for the first time. At the same time, the new car will also introduce a 2.0T plug-in hybrid vehicle in the replacement model for consumers to purchase. The cruising range of the new car in pure electric mode can reach 100km, and the AMG GLC 43 model will also be replaced with a 2.0T engine.

In addition, Mercedes-Benz’s new generation of GLC domestic models will join the 1.5T turbocharged model for the first time, and its market starting price will also be slightly lowered, which is more cost-effective than BMW X3 and Audi Q5L models.

As can be seen from the published preview picture, Mercedes-Benz’s new generation GLC tail is equipped with the same LED taillight group as Mercedes-Benz GLE, and the bilateral single-outlet exhaust layout will continue to be selected below. In addition, the new car will be built on the same platform as the mercedes benz c Class, and its body size will be greatly improved after the new car is officially launched. It is worth mentioning that the new generation GLC of Mercedes-Benz has also greatly improved the interior, adopting the same design elements as the C-class model, equipped with a 12.3-inch LCD digital instrument and an 11.9-inch inclined LCD central control screen.

On March 16th, Xiaomi officially announced that the original "Xiaomi Sports" application was renamed as "Zepp Life", which became the sports health application of Huami, and was subsequently operated independently by Huami. At the same time, Xiaomi launched a brand-new application "Xiaomi Sports Health" as the official application of subsequent Xiaomi wearable products, and the new application will gradually support users’ original data migration.

The announcement also shows that zepp Life application will continue to support the connection and use of existing mi band 1st-6th generation products, Xiaomi weighing scale series products and Xiaomi body fat scale series products, and the course data, sports health and other data generated during the use process will be kept on Huami server on the premise of ensuring the privacy and safety of users.

At the same time, Xiaomi will continue to deepen cooperation with Huami in product development, self-developed chips and algorithms in the wearable field, and jointly provide high-quality and leading wearable software and hardware services for rice noodles.

It is worth noting that the renaming of Xiaomi Sports APP is only the epitome of Xiaomi’s eco-chain enterprises in the eyes of the industry, because besides Huami, Roborock, Yunmi and No.9 Company have started to "stand on their own feet", get rid of the embarrassing position of being a millet agent and build their own product lines.

It is understood that as early as 2014, Xiaomi and Huami jointly launched the first generation of mi band. From 2015 to 2016, Xiaomi products contributed 97.1% and 92.1% of the current income to Huami.

Also in 2015, Huami started its "Demining Plan", released its own brand Amazfit, and then acquired the smart wearable brand Zepp in 2018, and successively launched the Huangshan series self-developed wearable device chip and the open platform Zepp OS, which were installed on smart wearable products such as Amazfit GT3.

The financial report of Huami Technology in the third quarter of 2021 shows that the shipment of its own brand increased by 89% year-on-year, while the shipment of wearable products such as OEM mi band decreased by 45.3%.

Although the shipments of private brands have increased significantly, the sequelae of "de-rice" have also followed. The financial report shows that in the third quarter of 2021, Huami Technology’s revenue was 1.6 billion yuan, down 28.1% year-on-year; Product shipments dropped from 15.9 million units in the same period last year to 9.9 million units, down 37.7% year-on-year; Net profit decreased from 81.1 million yuan in the same period last year to 49.3 million yuan, a year-on-year decrease of 39.2%.

Huang Wang, the founder, chairman and CEO of Huami, once said in a telephone conference that the revenue and profit in the third quarter dropped significantly, mainly due to the 45.3% year-on-year decline in shipments of wearable products such as mi band, which was contracted by Huami Technology.

As a star of science and technology innovation board, Roborock is also a member of "going to Xiaomi". In 2016, Roborock’s first intelligent sweeping robot product was customized for Xiaomi. A year later, Roborock began to launch independent brands such as "Stone" and "Xiaowa" series. During 2016 -2020, the proportion of private brand sales in Roborock was 0.9.64%, 49.83%, 66% and 90.72% respectively. In the first half of 2021, the sales proportion of Roborock’s own brand products has increased to 98.23%.

Roborock’s identity after "Demihua" will also be transformed into a new rival of Xiaomi in the field of car making. It is reported that Roborock has started the smart electric vehicle project Luotuo Automobile by the end of 2020, and completed the financing of 100 million US dollars by the end of 2021. Tencent and Sequoia both participated in the investment.

It is worth noting that similar "reincarnation" has also been staged in Xiaomi ecological chain enterprises such as No.9 Company and Yunmi. Even Company No.9 explicitly mentioned in science and technology innovation board’s prospectus that "the company does not belong to the typical ecological chain enterprise defined by Xiaomi."

Some industry analysts said that the eco-chain enterprises such as Sushi Technology, Yilai Intelligent and Fun Sleep Technology, which will be listed next, will still repeat the practices of their predecessors and resolutely "go to Xiaomi". At the beginning of the venture, Xiaomi’s strong supply chain integration ability and brand power can indeed provide a huge market and reputation endorsement for enterprises; However, if the enterprise has reached the stage of development and growth, and still relies too much on the ecological chain of Xiaomi, it will face the risks of reducing procurement and order quantity. If it wants to gain a bigger market or impact a higher-end market, it will tear off the label of Xiaomi to accommodate more labels and possibilities.

At the past Chengdu Auto Show, the first Kunpeng DHT hybrid model, Tiggo 8 PLUS Kunpeng e+, was launched, and the heat was still quite high. Since then, people around Kung Fu Car have been asking what the hybrid strength of Kunpeng DHT is. After all, it is the latest masterpiece of "Technical House" and whether it has surpassed the DM-i super hybrid system.

Kung fu car didn’t want to answer this question, but in fact, strictly speaking, the two are not a divination. DM-i is a HEV architecture made of PHEV, while Kunpeng DHT hybrid is a traditional PHEV architecture, adding some functions of HEV, which sounds a bit circuitous.

Let the Kung Fu car explain it to everyone. I can only say that these two can’t really hit each other.

(1) The biggest advantage of DM-I super hybrid is fast, economical, quiet and smooth.

First of all, it must be admitted that before DM-i, it has actually been mixed for many years, and it has also produced super-performance monsters with an acceleration of less than 5 seconds, but its influence is not the same as that of today’s DM-i, mainly because some key points have not been opened.

Let’s take a look at this ugly picture drawn by Kung Fu car. There are only six parts in total, which looks very simple, and this is the working schematic diagram of DM-I.

There are three driving paths, one is that the engine drives the generator and then drives the driving motor, the other is that the power battery drives the driving motor, and the third is that the engine directly drives the wheels through the clutch. Of course, it can also be driven by two sets of oil-electric drive chains at the same time, which is only used at ultra-high speed and rapid acceleration.

Very simple, in pure electric mode, it can be directly driven by battery, but at high speed with low motor efficiency, the engine will be directly driven. In most other hybrid modes, the engine drives the motor to work through the generator.

This is actually what we are trying to get through. The engine is more often used as a "charging treasure". It only uses the boring head to drive the generator to generate electricity, and then the motor only uses the boring head to drive the wheels. If there is excess electricity, it will be delivered to the battery. In this mode, the function of the power battery is greatly weakened, and it becomes an "energy pool". Of course, another point is that the engine can have average performance but high efficiency. After all, its biggest function is to generate electricity.

When driving in urban areas, 99% of DM-i vehicles are driven by motors, while 88% and 82% of DM-i vehicles are driven by motors under NEDC and WLTC conditions respectively. In other words, if you drive in the city, it is basically equivalent to a tram.

And what are the advantages of motor drive? First of all, it is fast. After all, it can output the maximum torque in the first time. Taking Qin PLUS as an example, its 0-100km/h acceleration time is 7.3 seconds, which is definitely fast enough. In fact, it is enough to save, not to mention pure electric driving. The fuel consumption in the state of power loss is 3.8L/100km. After all, the thermal efficiency of the engine is as high as 43%, while the conversion efficiency of the generator and the driving motor is above 95%. Then there is quietness and smoothness, which is also the inherent advantage of motor drive. After all, the acceleration of motor is absolutely linear, and the noise is much smaller than that of an engine with unstable speed.

Of course, in addition to being fast, economical, quiet and smooth, the DM-i system also has an advantage of being "green". The advantage of being able to get a green card allows it to reduce the dimension and attack electric vehicles. After all, the DM-i model has a comprehensive cruising range of more than 1200 kilometers, and just refuel, which fundamentally eliminates mileage anxiety, but it can still get a green card.

(2) Kunpeng DHT hybrid, dual-motor drive is the highlight.

Kun Peng DHT hybrid is the only hybrid system driven by dual motors in its own brand. It uses a special hybrid gearbox with multiple gear ratios to coordinate the work of engine and motor.

The core of this system is its hybrid gearbox, in which the engine supports three-speed transmission, plus the generator and driving motor, its generator itself can be driven, which is equivalent to three power sources. They cross out 11 gears, which can adapt to various road conditions. At the same time, it can also work in nine working modes, such as single and double motor drive, extended range, parallel connection and direct engine drive. The official saying is "three gears, nine modes and eleven speeds".

Theoretically, when a car has enough gears, its work will be more precise. After all, different gears correspond to different road conditions, but at the same time, the problem is that its control will be more complicated. In addition, although more gears can make the power output smoother, it is the coupling of oil and electricity through the gearbox, and it is impossible to be smoother and more linear than pure electric drive.

According to the data released by Tiggo 8 PLUS Kunpeng e+, the output power of its 1.5T hybrid special engine is 115kW, the maximum output power of the four-wheel drive version is 330KW, and the maximum output torque is 510Nm, even the output power of the two-wheel drive version is 240KW. This is still very powerful. The 0-100km/h acceleration time of its four-wheel drive model is 4.9 seconds, which is quite powerful.

Although no specific data has been released, it is revealed that the loss of electricity and fuel consumption of Tiggo 8 PLUS Kunpeng e+ is also good. After all, it also has a generator and has its own "hematopoietic" ability.

However, Kung Fu car is not optimistic that its power loss and fuel consumption will reach the same level as DM-i, because this generator is used for both power generation and driving. Considering the arrangement of its own three engines and four engines, the power generation will not be too large, but the power consumption capacity is quite strong, and the power conservation capacity is naturally not as good as that of DM-i with simpler structure.

In fact, the architecture similar to Tiggo 8 PLUS Kunpeng e+ has already been done before. It has more advantages in performance, relatively insufficient power-saving ability and higher cost. The result proves that the market influence is limited.

(3) Is the competitor of DM-I actually a fuel car?

At present, Tiggo 8 PLUS Kunpeng e+ has not been listed yet, which is actually not suitable compared with DM-i, which has a large number of systems.

Moreover, in Kung Fu car’s view, the biggest rival of DM-i model is actually not other hybrid models, but fuel vehicles.

Because other hybrid models can’t compete with DM-i at all, take the Tiggo 8 PLUS Kunpeng e+ as an example. It has three motors plus an engine, plus a quite sophisticated hybrid special gearbox. The DM-i has only two motors and no gearbox.

Both of them have their own advantages. The performance of DM-i is better due to power loss and fuel consumption, while that of Kun Peng DHT is stronger, but the cost of DM-i is much lower. It can make a hybrid car with a size close to Class B reach 100,000, which is unimaginable for Kun Peng DHT. And the simpler the architecture and the simpler the control logic, the less likely it is to go wrong, which is also common sense.

Furthermore, even if the architecture similar to DM-i can be achieved, it can’t be beaten. After all, in a world dominated by electricity, our advantages are too great. It is one of the largest power battery manufacturers, and also an excellent motor manufacturer. It is also a self-developed control chip, and its core technologies are still at an excellent level. If it is to fight for costs, other manufacturers have nowhere to start.

Therefore, if other hybrid cars want to compete with DM-i, I’m afraid they can only eat some relatively niche markets. For example, I don’t value price and reliability, so I want to speed up for a few seconds. Or the brand blessing is relatively large, and users are more willing to pay a premium. Even if the completion is not as good as DM-i and the price is higher, users are willing to pay the bill, but these are a minority after all. At least for now, DM-i is completely sweeping in the hybrid market.

And if you want to say that the model with the same dimension PK as DM-i is actually a fuel vehicle. After all, the fuel truck has simpler structure and more mature technology. Although the acceleration is not fast enough, smooth enough and quiet enough, many people don’t care so much about it. As for the higher fuel consumption, it can be offset by the difference in car prices.

Therefore, after DM-i came out, it has been promoting the subversive of fuel vehicles. This is its goal, that is, to change people’s car habits and make them pay more attention to driving experience, so as to tilt towards hybrid cars.

The voice of Kunpeng DHT is very high, but now it can’t compete with DM-I. It has its own advantages, for example, the engine has three gears, and dual motors can work with the engine at the same time to achieve stronger performance. However, its structure and control logic are a little too complicated, which is a great test for its working stability and will also push up the cost.

Therefore, the DM-i model with high probability will still be killed. As for Kunpeng DHT, let’s wait for it to be officially listed.

Recently, media reports on the latest developments in the wealth of China’s richest man, Wang Jianlin, pointed out that his wealth has shrunk from 220 billion yuan at its peak to 47 billion yuan at present, a decrease of nearly 5 times. Despite the huge decline in wealth, Wang Jianlin’s achievement is still particularly outstanding in China’s real estate industry. Looking back at the changes in China’s real estate industry in recent years, many peers such as Sunac’s Sun Hongbin and Evergrande’s Xu Jiayin are facing more severe challenges, and their companies have encountered debt defaults and broken capital chains.

Wanda Group, at the helm of Wang Jianlin, has shown forward-looking decision-making at a time when China’s real estate industry is facing difficulties. Six years ago, he foresaw the latent risks in the industry and decisively announced a business transformation. Wanda Group’s move to package up a large amount of land and projects was considered bold at the time, but from today’s perspective, it is a rather successful "escape" in business history.

The history of China’s market economy is relatively short, especially in the real estate sector, and many companies lack sufficient risk management experience in smooth sailing. It is this over-expansion that has led to the breaking of many companies’ capital chains and financial crises. In this context, Wanda’s transformation can be said to have successfully avoided the situation of total annihilation. However, transformation is not easy, especially for a large-scale commercial real estate company. Wanda’s transformation faces many challenges, including a bet agreement with investors of up to 30 billion yuan, and various uncertainties in the context of the changing economic macro environment.

Although Wang Jianlin’s wealth has shrunk, in such a market environment, he still shows the wisdom and persistence of entrepreneurs. Although Wanda faces challenges, it is not broken, but is trying to find a new way to survive and develop. The future development of Wanda Group is still full of variables, but Wang Jianlin’s experience and decision-making undoubtedly provide important inspiration for Chinese entrepreneurs: in the fluctuation of the market, predictive decision-making and flexible adaptability are the keys to the survival and development of enterprises. As Wanda Group continues its transformation path, we have reason to believe that there will always be more solutions than difficulties, and there will always be hope in the future.
