As the world’s first exclusive intelligent body control system for new energy, Yunqi has been receiving much attention since its release in April. Nowadays, the cloud system has been gradually installed on various models of BYD, allowing more users to experience the power of cloud technology. The cloud system was developed by BYD, which made BYD the first enterprise to master the 3-way 6-degree-of-freedom body control technology. BYD’s first product matrix of Yunqi, which currently includes Yunqi -C, Yunqi -A, Yunqi -P and other products, can greatly enhance our driving experience in many aspects such as comfort, handling, safety and off-road.

　　It is luxurious to carry, and Yunnian -C creates a new experience of driving and leaping forward.

　　Yunqi -C intelligent damping body control system can realize rapid and continuous variable adjustment of damping through thousands of signal inputs per second. At the same time, with the cloud algorithm, the optimal damping control scheme can be output in real time to meet the needs of users in different scenarios.

　　During the test drive of Han DM-p Ares Edition, it can be clearly felt that Yunqi -C makes the chassis "hard" by adjusting the damping, which provides greater support for the body and makes the driving and handling feeling of the whole vehicle more stable. At the same time, in the face of bumpy road conditions such as speed bumps and gravel roads, Yunxiao -C can make the chassis "soft", effectively buffering the impact of the road surface on the whole vehicle and greatly improving driving comfort. Whether it is a test of the sense of control or an experience of comfort, Yunqi -C’s performance is amazing.

　　Exercise and comfort are perfectly compatible, and Yunnian -A sets a new benchmark for luxury and comfort.

　　Yunqi -A intelligent air body control system can give consideration to both driving maneuverability and comfort, and at the same time, output precise control strategies through Yunqi Intelligent Computing Center to realize dynamic adjustment of vehicle stiffness, height and damping, and bring more detailed and diversified control to the whole vehicle.

　　In the process of experiencing Tengshi N7 equipped with the standard version of Yunqi -A, the most intuitive feeling is convenience, comfort and luxury. It can realize the functions of welcoming guests and taking things conveniently by adjusting the height, which makes it more convenient for us to get on and off the bus and move things in our daily life. In case of sudden acceleration or sudden braking during driving, the iCCT intelligent comfort control technology carried by Yunqi -A can achieve stronger anti-pitching ability, effectively restrain the vehicle from raising its head and nodding, and greatly reduce the discomfort of the passengers.

　　However, when faced with the scene of high-speed steering such as Panshan Highway, Yunqi -A can not only restrain the roll of the car body, but also integrate suspension, braking and driving through iCVC intelligent vector control technology. Even in the face of the difficult continuous mountain curve, it can easily enter and exit the curve with a very steady posture, and it is handy to control. With the help of iADC intelligent drift control system, drift is no longer the exclusive skill of "high-level players", and even ordinary people can enjoy drift with one click. Yunqi -A has achieved a perfect integration between luxury driving and interesting handling, and the overall experience is impressive.

　　Let cross-country have no threshold, and Yunqi -P brings subversive experience.

　　Yunqi -P intelligent hydraulic body control system integrates three core technologies of machinery, hydraulics and electronic control to fully meet the off-road needs of users. Yunqi -P can adjust the height, damping and stiffness. When driving U8 in mountain road, you can obviously feel that the road vibration is filtered completely, and the support is also in place in the corner. It is not like the traditional hard-core SUV, and there will be no many small vibrations. For Yunnian -P, this kind of comfort experience on unpaved pavement is unprecedented.

　　Looking up at U8 and Equation Leopard 5 under the blessing of Yunnian -P can not only realize the long suspension adjustment stroke, but also have the "hidden function" ultra-high and ultra-low mode. Therefore, even a behemoth like U8 can "hold the bottom" in extreme off-road conditions and "touch the head" in the urban restricted highland basement. At the same time, Yunqi -P with strong off-road performance has also added intelligent genes. The four-wheel linkage function can intelligently distribute the oil pressure through the central control cylinder, so that the four wheels can keep touching the ground at all times, which greatly improves the off-road passability. When parking in the wild, you can also keep the vehicle absolutely level by camping leveling function, so that the rest in the car will no longer be disturbed by terrain. It can be said that Yunqi -P greatly lowered the cross-country threshold, allowing Xiaobai to cross-country easily, bringing unprecedented experience to drivers and passengers.

　　BYD leads the industry with cloud technology.

　　Most importantly, Yunqi started from the systematic control of the vertical direction of the whole vehicle, and realized the safety of the whole vehicle. On the one hand, it can greatly reduce the risk of vehicle rollover and increase the safety of passengers by restraining the change of body posture; On the other hand, the cloud system can adjust the posture of the car body at any time through 3-to-6-degree-of-freedom fusion control under complex road conditions such as snow, mud and water. The cloud chariot system can not only effectively protect the safety of passengers, but also effectively protect the car body, and truly realize the dual protection of people and cars.

　　In the future, BYD will also launch Yunqi -X, which represents the highest level of the global body control system. At the press conference, BYD had already demonstrated the power of Yunqi -X by looking up to U9 for dancing and three-wheeled driving. Recently, Porsche Active Ride, the new hydraulic active suspension system of Porsche’s third generation Paramera, has also earned enough attention in the form of "dancing". Different from Porsche, BYD Yunqi -X is more advanced in system design ideas and realizable functions through innovative new energy architecture. This also proves that BYD has been at the forefront of the industry in the field of body control, and will continue to lead the development direction of the industry with forward-looking technical layout.

　　Through the experience of the whole family of Yunqi, we can clearly feel the overall improvement of the comfort, handling and off-road performance of Yunqi. There is no doubt that Yunqi is a super technology with the ultimate experience and safety. As BYD’s cutting-edge black technology, Yunqi’s birth not only fills the gap in the field of domestic body control technology, but also enables more domestic users to experience the high-end driving and control experience, and further realizes the technological transcendence of established western car companies and promotes the world’s automobile technology to a new height.

China automobile brands have never given up on the impact on the high-end market. Especially in recent years, with the "Matthew effect" of the automobile market becoming more and more fierce, the leading independent brands have become more and more brave, and they have independently developed and established technical highlands to launch more competitive products in the market.

With the accumulation of sales volume, the market has proved that the high-end models launched by China brand will not lose joint venture models, whether it is Yan value power or configuration quality control. Among them, the most outstanding performance is undoubtedly Han, and the cumulative sales volume in one year has exceeded 100,000 units.

It is worth mentioning that in the past year, there were 1,127 models on sale in China, of which only 43 models sold more than 10,000 yuan a month. Among them, there are only 8 high-end cars with an overall price of more than 200,000 yuan, of which 4 models are C-class cars, which are,, and Han. In the case of chasing after the tigers, Han was able to stand firm in the market segment of medium and large C-class high-end cars, which gradually proved consumers’ recognition of independent high-end models.

Why does Han stand out from the encirclement?

In fact, there are many independent brands that introduce new models to the high-end market every year, and even some car companies spend a lot of money to invite world-class design and management teams, but few independent brands have successfully squeezed into the high-end market, but why did Han succeed?

Everyone who knows it knows that Wang Chuanfu’s ideas and ideas have always been very advanced. When most independent brands earned their heads off for fuel vehicles, they entered the new energy vehicle market more than ten years ago. It is also Wang Chuanfu’s advanced strategic vision that has been leading the rapid development to become the leader of new energy vehicles today.

Twenty years ago, it was impossible for people to imagine that a battery manufacturer had become the only leader in the field of new energy vehicles. As a car company that started with batteries, it is indeed at the forefront of independent car companies in the new energy vehicle market.

With the continuous investment in R&D and innovation, we have mastered the core technologies of the whole industrial chain of new energy vehicles, such as batteries, motors and electronic controls, and are the only car companies in the world with the core technologies of "Three Electricity", which cannot even be achieved. At the same time, in the current global chip shortage, it is also one of the few car companies that are not troubled by the chip shortage, because they can make chips themselves and do not need to rely on foreign imports.

It is also with strong technical strength as a support that its Hanergy has made great efforts in the new energy vehicle market and even begun to seize the market share of fuel vehicles. In July, the total sales volume was 56,975 vehicles, up 89.4% year-on-year and 14.5% quarter-on-quarter, setting a new brand sales record. Among them, the sales of new energy vehicles accounted for 87.85% of the total sales, which further increased compared with June, reaching 50,057 vehicles. As a representative of autonomous medium and large cars, Han also captured the perfect data of 8,522 cars in July, and in June, the cumulative sales volume exceeded 100,000 cars, which was fully recognized by consumers.

At present, the cumulative sales volume in the new energy market has already exceeded 1 million vehicles, making it the only car company in its own brand that has exceeded 1 million vehicles. From this series of sales data, it is not difficult to see that it has successfully changed from a fuel vehicle enterprise to a new energy vehicle enterprise.

Technical strength is the key to breakthrough.

The core technology is the survival of car companies. Knowing this truth, in the past two years, the research and development of new technologies has constantly subverted the outside world’s perception of the industry. From last year’s "blade battery" to this year’s DM-i super hybrid technology, the advent of each new technology has brought subversive effects.

Chairman Wang Chuanfu once said, "Safety is the greatest luxury of electric vehicles". As one of the core components of electric vehicles, the safety of batteries largely determines the safety performance of electric vehicles. The emergence of "blade batteries" has raised the safety of batteries to a new height, and at the same time, it has made Han stand out in the highly competitive automobile market.

As we all know, the traditional power battery produces the battery core in the form of winding, while the "blade battery" adopts the lamination process. Compared with winding structure, laminated structure has more uniform current density, excellent internal heat dissipation performance and is more suitable for high power discharge. This is like a box of the same size, one full of ping-pong balls and the other full of straightedge. We can easily imagine the help of lamination technology to space utilization. Therefore, the blade battery has better cycle characteristics, safety characteristics and energy density.

Among more than 300 safety tests of power batteries, acupuncture test is recognized as the most demanding test, which can be called the "Everest" of battery safety test.

The acupuncture test removes all the outer garments of publicity packaging, so that the true safety of the battery is naked in front of consumers. No one wants an unstable and explosive battery sitting under his ass. Blade battery became famous by acupuncture test in World War I, and its natural safety skill was promoted to a unique position through the acquired technological blessing.

Self-cultivation of flagship models

It has been a year since Han went public. After nearly a year’s investigation, Han did hand over an answer sheet worthy of the flagship model.

However, with the intensification of competition in the automobile market, the range of consumers’ choices has gradually expanded, so while digging deep into demand, they are also constantly striving to meet the consumption upgrade. For example, the newly listed 2021 Han EV standard endurance luxury model, compared with the 2020 Han EV ultra-long endurance luxury model, only reduces the battery capacity, and other configurations have not changed, but the price has dropped by 20,000 yuan, which is enough to be seen, bringing consumers unexpected product value and charm.

From the perspective of positioning and selling price, the direct competitor of Han EV is undoubtedly that the listing of the 2021 standard endurance luxury version of Han EV has not caused much pressure, because the comprehensive strength ratio of Han EV is better.

From the price point of view, the price of the 2021 Han EV standard endurance luxury model after subsidy is only 209,800 yuan, but the comprehensive cruising range can reach 506km；; The starting price after subsidy is 235,900 yuan, which is not only 26,100 yuan higher, but also the comprehensive cruising range is only 468km.

In terms of charging time, even if it is fast charging, it takes 1 hour to wait, while the fast charging time of the 2021 Han EV standard battery life version is only 0.42 hours, which is about 25 minutes. In other words, compared with Han EV, it not only runs farther, but also has a shorter waiting time for charging, which is especially critical for pure electric vehicles. Another point that has to be mentioned is that the safety in China is well known to all, and consumers have their own opinions on who is safer between the two.

Faced with the continuous price reduction, from the new forces of car-making to traditional car companies, most of them avoid their sharp edges and do not confront them head-on, while Han EV chooses positive hard steel, which is undoubtedly supported by strong technical strength.

Write at the end:

As a well-deserved leader of independent new energy vehicles, the road to transformation is not easy. Behind this is decades of technical research, which gives you a proud technical idea and a competitive capital.

The launch of the 2021 Chinese EV standard endurance luxury car further extends the benchmark product advantage of the Chinese EV industry to the market segment of 200,000+mid-to-high-end pure electric cars, and demonstrates the strength and confidence of China New Energy flagship car to continue to lead the market.

With the approaching of the listing date of M9, more and more information is exposed. Recently, a person close to the supply chain revealed that the innovative composite current collector of lithium battery is expected to be applied in the M9.

The composite current collector is a sandwich structure of "metal -PET/PP polymer material-metal", which replaces the original pure metal foil. It has the application advantages of high safety, long life, high energy density and low raw material cost, and is expected to replace the traditional current collector and become the mainstream material of lithium battery current collector in the future.

Guangzhou Automobile Ai ‘an released magazine battery 2.0, which is the first battery in China to announce the adoption of composite current collector. The first model is Haoplatinum GT. At the launch conference of the car, Ai ‘an also announced the test report of the bullet shooting fully charged battery pack. The results showed that the bullet penetrated three batteries, which caused the battery pack to be short-circuited and burst in an instant, but the battery pack just smoked and did not catch fire, and the temperature dropped to room temperature after standing for 24 hours.

In addition, Contemporary Amperex Technology Co., Limited Kirin battery has adopted a composite current collector, which is mounted on pure electric MPV Krypton 009.

According to the research report of CITIC Jiantou, the composite current collector is both safe and economical, which is a major innovation in lithium batteries. In 2023, the industrial trend has gradually become clear and accelerated significantly, and equipment manufacturers, new copper foil factories, battery factories and end users have accelerated their layout; At the same time, the technology continues to break through, promoting the composite current collector to mass production, and 2023 is expected to become the first year of mass production.

Wen | Buer Research Institute Yi Xin Zi Qing

Following the price reduction of Tesla at the beginning of the year, in August this year, new energy vehicles once again set off a new wave of price reduction. Brand officials, such as Zero Run and Weilai, announced the price reduction, and the ideal was to "reduce the price in disguise" by releasing new cars.

On August 8th, LI (02015.HK) announced the second quarterly report of 2023. Although the net profit of the second quarter increased, its share price showed the opposite trend.

On the day of the financial report, its US stock price closed down by 8.62%; The next day (August 9), Hong Kong stocks closed down 5.52%.

As of August 14th, LI closed at HK$ 160.90 per share, corresponding to a market value of HK$ 335.4 billion (about RMB 311.1 billion).

According to the latest data released by Ideal, its delivery volume in the second quarter reached 86,533 vehicles, up 201.6% year-on-year and 65% quarter-on-quarter. In July, the delivery volume was 34,134 vehicles, up 227.5% year-on-year and only 4.7% quarter-on-quarter.

According to the announcement of LI, it is estimated that the delivery volume in the third quarter is only 100,000-103,000, equivalent to 33,000-34,500 vehicles per month. Based on this data, it is speculated that the growth of ideal monthly delivery volume may stagnate.

According to its second quarterly report, "Buer Research" found that in the second quarter of this year, LI’s revenue was 28.65 billion yuan, a year-on-year increase of 228.1%; The net profit was 2.31 billion yuan, turning losses into profits year-on-year, up 147.4% from the previous month.

In the second quarterly report, the ideal revenue doubled, but the strategy of re-marketing may continue. The R&D expenditure in the ideal second quarter was 2.43 billion yuan, up 58.4% year-on-year and 31% quarter-on-quarter. Sales, general and management expenses were 2.32 billion yuan, up 74.3% year-on-year and 40.4% quarter-on-quarter.

At present, LI’s production capacity is limited to 8,000 vehicles per week, and the production capacity of parts suppliers has fallen into a bottleneck, which is also a challenge it faces in the second half of the year.

According to the financial report meeting in the second quarter, due to the development of economic situation and the upgrading of enterprise organization matrix at the beginning of the year, it is ideal to lower the planned annual sales target of 360,000 vehicles to 300,000 vehicles.

Today, the new energy vehicle has entered the second half, and the industry volume has been intensified; Although LI turned losses into profits year-on-year, how long can the story of its profitability be sustained and increased?

In March of this year, the new forces of building cars suffered a double crit.

The first crit comes from the continuous price reduction war of peer TSLA, and the second crit is the government-enterprise subsidy jointly initiated by Hubei Dongfeng. The fuel vehicle market is "chaotic", which makes new energy vehicles suffer crit.

As one of the Three Musketeers, a new force in car-making, LI has previously published the 2022 annual report and the first quarterly report in 2023. Although the revenue in 2022 has achieved substantial growth, it is still at a loss.

According to its financial report, "Buer Research" found that in 2022, LI’s revenue was 45.29 billion yuan, a year-on-year increase of 67.7%; In the same period, its net loss was 2.03 billion yuan, up 531.42% year-on-year, making it the most serious year since the listing of US stocks in 2020.

Among them, the ideal automobile sales revenue in 2022 is 44.106 billion yuan, accounting for 97.39% of the total revenue. According to "Buer Research", due to the increase in R&D investment and rising operating costs in 2022, the automobile sales revenue failed to catch up, which led to the further expansion of LI’s net loss.

Under the new energy automobile track, it still takes time to accumulate and reserve funds to transform R&D investment into automobile production capacity.

Although the capital reserve has been expanded after the dual listing, more and more car-making competitors and intensified competition in sub-sectors seem to be shortening the ideal "new" time window.

01 landing in Normandy

In 2015, after leaving office in car home, Li wanted to start a business again, aiming at the field of new energy vehicles. At that time, Tesla was in the limelight, and many Tesla "fans" emerged in China.

Source: LI founder-Li Xiang-LI Guan Wei

Since then, Li Xiang’s brand ideal of new energy vehicles has stood out, and he, together with Weilai Automobile and Xpeng Motors, has been called "Three Musketeers".

In 2019, when the ideal first car, Li ONE, was officially launched, Li Xiang said frankly, "I have been in business for 20 years, and today is my most nervous day, and it is also the Normandy landing day of the company".

In July 2020, above the new energy outlet, it was ideal to land on Nasdaq in the United States, and the IPO was priced at $11.5 per share, with the highest increase of more than 50% on the first day of opening.

On August 12, 2021, LI landed on the Hong Kong Stock Exchange, becoming the second new car-making force to achieve dual listing in Hong Kong stocks after Xpeng Motors.

Although the new energy outlet is still there, the competition of the Three Musketeers, a new force to build cars, is intensifying. Compared with the increasingly full product matrix of Weilai and Tucki, the outside world is quite worried about the ideal car-making pace: the 2020 Li ONE that landed in Normandy has been sold for nearly three years, and the ideal finally got the new 2021 Li ONE.

Source: official website, LI

According to the ideal quarterly report in 2023, its total revenue in the first quarter was 18.79 billion yuan, up 96.5% year-on-year and 6.4% quarter-on-quarter. In the same period, the net profit was 934 million yuan, turning losses into profits. In addition, the ideal annual gross profit margin in the first quarter of 2023 is still declining.

According to "Buer Research", the ideal main revenue source is vehicle sales, and its vehicle sales revenue in the first quarter of 2023 was 18.33 billion yuan, accounting for 97.55% of the total revenue.

The increase in sales revenue in LI is mainly due to the increase in delivery volume in the first quarter and the increase in the average selling price of ideal L series models. In addition, the revenue and delivery have been greatly improved, which has also enabled LI to turn losses into profits.

Entrepreneurship means choosing the path of extended-range technology and relying on an extended-range electric vehicle to conquer the world. The ideal can be described as a different kind among the three musketeers, a new force in building cars. However, the increasingly strict policy supervision is like the sword of Damocles hanging overhead, and it is ideal to make up for the autopilot technology.

Li Xiang once said frankly, "In terms of autonomous driving, compared with Tesla and Tucki, we have to make up lessons." According to the plan, this year’s ideal research and development is continuously invested; In the first quarter, its R&D expenditure was 1.85 billion yuan, up 34.8% year-on-year; In the second quarter, its R&D expenditure was 2.43 billion yuan, a year-on-year increase of 58.4%.

When the market structure of the new force of car-making is initially determined, the competition of new energy vehicles has entered the second half: the sales and mass production targets of 280,000-300,000 vehicles, and the fierce competition of autonomous driving technology.

As a supporter of the "10,000-hour Law", Li Xiang once wrote in Weibo, "I have trained more than 60,000 hours in the automobile industry since 2004, and I am more confident in my major".

It seems that the capital market that votes with its feet is not satisfied with Li Xiang’s "10,000-hour law".

By comparing the PE value (P/E ratio) and the PB value (P/B ratio) of the Three Musketeers, a new car-making force, it was found that by the close of the US stock market on August 12th, EDT, except LI, the PE values of the new car-making force were all negative, with the PB values of Tucki 2.81, Ideal 6.23 and Weilai 7.63 in turn, while the PB value of Tesla was 15.06.

Among the three musketeers, the ideal PB value ranks second, which is about 1/10 of Tesla PB value. The higher the PB value, the higher the valuation of enterprises in the capital market.

As of August 12th, EST, the US stock market closed, with an ideal market value of $42.18 billion, while Tesla’s market value has passed the $700 billion mark.

02 on the new speed.

On May 25th, 2021, Ideality released the 2021 Li ONE in Beijing, which was different from the enthusiastic conference site. The capital market reacted coldly and fell immediately after the opening of the day. Only one day later, it is ideal to announce the financial report for the first quarter of 2021, from profit to loss.

"Li Xiang, you owe an explanation to the owner who picked up the car in April and May." After the release of the 2021 Li ONE, Li Xiang’s Weibo was overwhelmed by the owner’s doubts.

According to the ideal plan, after the production and sales of the 2021 Li ONE model begin, the production of the 2020 model will stop. The car owner who just bought the old model of Li ONE soon felt that he had been "cleared of inventory" by routine. Although it is ideal to provide four paid upgrade schemes for old car owners, it still cannot satisfy the skeptics.

In August of the same year, a similar scene was once again staged in the ideal riders group: the prospectus revealed that the ideal will launch a new full-size SUV in 2022, and compared with the existing products, the size, hardware and intelligent configuration have been improved in many aspects.

Source: LI Guanwei

To some extent, the rapid iteration of new energy vehicles is accelerating the depreciation of the value of the previous generation models. Anxiety, confrontation and other emotions spread between riders waiting for a full-size new car and owners who have already picked up the car.

According to "Buer Research", the innovative technology of new energy vehicles is both a spear and a shield. Compared with traditional cars, the product cycle of new energy vehicles is shorter; How to balance customer perception and product iteration has also become an ideal test.

However, the other side of the coin is the risk brought by the thin product line, and any fluctuation in Li ONE may trigger a chain reaction.

In order to change this situation, it is ideal to replace Li ONE with L8 and L9 from the second half of 2022.

In the fourth quarter of 2022, the ideal delivery volume was 46,319 vehicles, a year-on-year increase of 31.5%; In the same period, Weilai and Tucki delivered 40,052 vehicles and 22,204 vehicles respectively, both of which increased year-on-year.

By the end of 2022, it is ideal to deliver 133,246 vehicles throughout the year, up 47.2% year-on-year; Although it did not reach the expected goal of LI, it was slightly ahead of Weilai Automobile’s 122,486 vehicles and Xpeng Motors’s 120,757 vehicles in terms of the number of deliveries in 2022.

By the end of January this year, LI’s monthly sales even exceeded the combined monthly sales of Weilai Automobile and Xpeng Motors.

In the first quarter of this year, the ideal delivery volume was 52,584 vehicles, a year-on-year increase of 65.8%; The deliveries of Weilai and Tucki in the same period were 31,041 and 18,230 respectively.

The outbreak of black swan is only a small probability event. If compared with the same industry, to some extent, the large data fluctuation of ideal sales revenue is related to its single product structure.

In the view of "Buer Research", in the early stage of starting a business, the 2020 Li ONE solo combat can unite all the superior resources; However, due to the lack of product matrix, ideal is losing its position in the price range, and it is easy to fall into the situation of weak subsequent growth.

Expanding the product matrix is imminent. On August 3 this year, it officially launched the ideal L9 Pro. According to the ideal plan, it is expected to launch the first pure electric vehicle MEGA； by the end of 2023. And in 2024, four new cars will be released, including an extended-range SUV and three pure electric models.

It is not easy to "upgrade" new energy vehicles, and R&D investment is similar to "arms race"; Only from the number of patents and invention patents in 2020, the ideal is relatively backward.

Intelligent driving is the focus of LI’s current layout. This year, the ideal plan is to land the "NOA" function in 100 cities.

At present, LI has successfully opened the urban NOA internal test in Shanghai and Beijing, and completed the first test drive of urban NOA and commuter NOA in Beijing. It is expected that in the third quarter, Ideal will also open the commuting NOA function to "early bird users".

In the view of "Buer Research", when the potential of new energy vehicle track is highlighted, attracting many car-making forces to enter the market, the competition in market segments will become more intense.

Regardless of the technical path, ideally, the time window of the new product matrix is limited, and it is urgent to find a balance between iterative novelty and customer perception.

03 Flag of Li Xiang

In February 2021, Li Xiang said in an internal letter that by 2025, it is ideal to win 20% of the market share and become the first intelligent electric vehicle enterprise in China; In 2030, it will go further and become the first intelligent electric vehicle enterprise in the world.

In the second quarter of this year, Li Xiang set a new Flag: the ideal total sales this year will exceed the target at the beginning of the year by 10%-20%. The ideal target at the beginning of the year is annual sales of 306,000 vehicles, and the adjusted sales volume is expected to be 336,000-366,000 vehicles.

According to the latest data released by Ideal, its delivery volume in the second quarter reached 86,533 vehicles, up 201.6% year-on-year and 65% quarter-on-quarter. And delivered 34,134 vehicles in July.

In terms of production capacity closely related to the delivery volume, the "Buer Research" found that the annual production capacity of the ideal Changzhou factory in 2020 will be about 100,000 vehicles, and the annual production capacity of the factory will increase to 200,000 vehicles after upgrading.

After the release of Q3 financial report in 2022, Shen Yanan, the ideal co-founder and president, announced his resignation. He helped LI choose to build his own factory in Changzhou. This adjustment is regarded as a large-scale change since the establishment of Ideal.

At the ideal second-quarter financial report meeting on August 8, Li Xiang said that at present, due to the influence of supplier supply, the production capacity is in a bottleneck.

Earlier, there were media reports that Ideality was contacting Beijing Hyundai and hoped to receive its first factory that had stopped production. At present, the Beijing base is expected to be officially put into production at the end of this year. In addition, it is reported that the production plan of the ideal third factory, Chongqing production base, has stopped.

According to "Buer Research", if we want to achieve production and sales of 1.6 million vehicles in 2025, we need a strong production capacity reserve. The only Changzhou factory and Beijing factory may not have enough production capacity to carry their delivery demand, so the construction of new factories is imminent.

Previously, compared with the other two new car-making forces, the ideal offline layout was not dominant and is currently accelerating.

By June 30, 2023, LI had operated 331 retail stores covering 127 cities. In addition, LI operates 323 after-sales maintenance centers and authorized car body and painting centers in 223 cities.

When Internet companies such as Baidu and Xiaomi went off to build cars one after another, the war of new energy vehicles intensified. Regarding the cross-border showstopper, Li wants to speak frankly about the car, saying that the car sales can’t be faked, and the final development depends on the final product.

Although LI is speeding up its running, will Li Xiang’s Flag fall down under many skinny realities?

"Ideal" meets the cold reality

Although the ideal delivery volume since 2023 has been leading the new domestic car-making forces, LI still considers 2023 as "Alexander". In particular, the head car companies headed by Tesla started a price war, which caught the industry off guard.

However, as a "hardware for traffic portal, software for charging service", Tesla model seems to bring new imagination space for new energy vehicles.

When the income of Tucki XPILOT software and Weilai NIOPILOT software increased, Li Xiang declared: "The new Li ONE autopilot is standard, and the future ideal will not charge for autopilot".

"With the development of smart cars, there will be more and more usage scenarios for users and more and more business models." Li wants to put his hopes on another possibility of business model innovation, but it needs to be built on the basis of ownership.

Che Gewana once said, let’s be loyal to our ideals and face reality. On the increasingly crowded track, Li wants to be loyal to his ideals, but he also needs to face reality: the day after tomorrow of new energy vehicles is beautiful, and today is very difficult. The key is whether he can survive tomorrow.

　　BEIJING, Oct. 14 (Xinhua) Recently, the popular anchor Ti mo Feng sent Weibo, saying: "The contract with DouYu has expired, and future cooperation is still under negotiation … … 。” Weibo, who is less than 100 words, caused a hot discussion among netizens, and once pushed Ti mo Feng to a hot search in Weibo.

　　Netizens are guessing, where is Ti mo Feng’s next stop? Where to? This may be a difficult choice for online celebrity anchors represented by Ti mo Feng in their career development.

　　From Ti mo Feng’s announcement of her freedom to her negotiation with Tik Tok Platform, all the signs show that Ti mo Feng wants to make a leap from online celebrity to a star. Her subsequent development will also become a typical sample for the outside world to observe the development of online celebrity anchor.

　　Ti mo Feng won a large number of fans on the live broadcast platform with her beautiful voice. Not long ago, she also held a solo concert in her hometown of Chongqing and attended variety shows such as talk shows. After moving to Tik Tok, Ti mo Feng has reached more than 30 million fans, trying to compete with first-line traffic stars such as Show Lo, Joker Xue and Yang Mi for fans and attention.

　　Although he occasionally ranks in the TOP10 of Tik Tok’s celebrity love dou list, Ti mo Feng may still have a long way to go to achieve the leap from online celebrity to celebrity.

Screenshot from the network Weibo

　　What is the work and commercial value?

　　For example, Show Lo, who ranks in the forefront of Tik Tok, has made numerous films and TV songs for more than 20 years, and his hosting programs are deeply rooted in the hearts of the people. Joker Xue won numerous music awards and was very popular. These stars also have commercial value, such as the release of Jay Chou’s new song, which earned 15 million music revenues overnight, which fully reflects the strong commercial appeal of the stars.

　　On the other hand, Ti mo Feng has gained some fans with several music works since her debut, but it is also confined to the live broadcast circle, far from reaching the popularity of first-line stars. More importantly, she didn’t come up with bright works to establish her star status.

　　In terms of revenue, in September 2019, Ti mo Feng’s data of small gourd ranked 38th on the fighting platform, with 895,000 monthly active fans in the live broadcast room and an average monthly reward of 209,000. Its income index ranks 30th in Betta platform, popularity index ranks 75th in Betta platform, and powder increasing index ranks 57th. The three indices in August ranked 43rd, 52nd and 28th respectively. Thus, Ti mo Feng’s commercial value is far from matching her status as a "fighting fish elder sister".

　　Does online celebrity anchor have strong entertainment system support?

　　A online celebrity wants to become a star, which requires not only his own professional ability, but also a perfect entertainment system. This entertainment system is rooted in the entertainment market, and it continuously supports a star’s popularity and market recognition through a series of means such as artist training, brand packaging, resource promotion, exposure and publicity. However, online celebrity anchor is rooted in the live broadcast soil and lacks the support of this entertainment system. It is very difficult to achieve the leap from anchor to star.

　　Then there is the short life cycle of online celebrity anchor. There is even a saying in the industry that online celebrity’s life cycle is only two years. For the predictable aesthetic fatigue of users, most anchors may not escape this fate. Fans like anchors that provide novel perspectives and unique experiences. When people get used to this method, they will get bored and finally start to pursue the next online celebrity. Therefore, under such circumstances, online celebrity anchor should extend his life cycle in the fields he is familiar with and good at. However, online celebrity anchor’s pursuit of stardom still faces great challenges.

　　What is the geometry of the anchor winner of job-hopping

　　If Ti mo Feng moves to Tik Tok, will it bring her a leap forward? On the contrary, many anchors have switched to other platforms, but few have developed better than before. For example, Brother Snake, the anchor of the fighting fish Jedi survival plate, quickly became popular because of his sharp play, handsome face and fighting fish flow blessing. However, in the end, Brother Snake broke his contract and left Betta, and went to Huya for live broadcast. His popularity declined and gradually became a second-line anchor. In addition, there are anchors such as Hyun Shen, Du Ji, Bai Yinfei, Bao Zi, etc. After they left the original platform, their status and popularity were not as high as before.

　　Industry analysts believe that this is related to the anchor not adapting to the new environment. On the original platform, the anchors are familiar with the ecological environment of the platform, and it is easy for the anchors to achieve the best live broadcast state. Once you switch to other platforms, the unfamiliar environment will affect the performance of the anchors. Secondly, this is related to the platform operation strategy. The anchor switched to other platforms, and these platforms hope that the anchor can bring fans to the new platform. But now the high-quality content of the platform leads to very high stickiness of fans. Only a few will migrate to other platforms with the anchor. Once the platform finds that these anchors can’t bring the expected traffic and revenue, it will reduce resource support and anchor revenue, and some anchors even return to the original platform.

　　Where should Ti mo Feng go? No matter how Ti mo Feng chooses, it shows the career development dilemma of online celebrity anchor. Faced with such a dilemma, Ti mo Feng may be the best choice to stay in Betta. After all, Ti mo Feng has been fighting fish for five years, Ti mo Feng and her fans are familiar with the ecology of fighting fish, and fighting fish has also made Ti mo Feng. The cooperation between the two sides may give Ti mo Feng more room for imagination in the future.

Recently, "tourism partners are accused of being involved in pornography" has attracted attention.It is reported that some netizens found on a social platform that "all-inclusive travel expenses" is becoming a code word. Under the eye-catching title of such posts, it is usually indicated that "girls only, each takes what he needs". In response to this matter, on the 30 th, the relevant staff of the social platform said that at present, a full-scale review has been carried out for the notes related to the "travel partner" in the station, and the problems reflected by the users mentioned in the article have not yet been located. Once the illegal content is verified, the illegal users will be seriously dealt with according to the law.(August 31st.　China News Network)

With the fiery travel, young people are eager to complete a beautiful trip with the partners who resonate with the same frequency, and the "travel partner" comes into being. Behind the "tourism partner", it reflects the new needs of the younger generation in social and tourism consumption. They find travel companions through social media platforms or specific applications and reach a consensus on travel. This way encourages people to get out of the comfort zone, establish contact with strangers and create a unique and unforgettable travel experience together. However, the beautiful vision of sharing travel experiences has changed in social media platforms.

The emergence of new things is bound to be accompanied by some new problems, and the disadvantages of social interaction are gradually emerging. Some lawless elementsBorrowThe name of the child, the fact of illegal transactions, makes the original pure travel contract a tool for illegal crimes. Social networking with partners is plagued by abuse and misleading on social media platforms: for example, words such as "all-inclusive expenses, optional location" or "girls only, each with his own needs" appear from time to time in the copywriting, and some users even mentioned that they were asked if they were looking for a "green partner". The dissemination of this information not onlyGedaSub-socialization itself casts a shadow, which raises people’s concerns about their privacy and security. The existence of this kind of behavior has undoubtedly pushed the social interaction of partners to the forefront of morality and law, and the future development of social interaction of partners has become vague and uncertain.

The response of the platform involved has taken a positive step.DandaThe abuse of sub-socialization exists not only in one platform, but also in other social platforms. Therefore, all major social platforms should strengthen the audit mechanism, strengthen the monitoring and control of platform content, and contribute to optimizing the network ecological environment. Government departments also need to continue to exert their efforts in supervision, formulate relevant laws and regulations, and severely punish the abuse of social partners for illegal transactions. In addition, the public’s own risk awareness and moral values are equally important. Virtual identities on the Internet are often difficult to distinguish, and it is not uncommon to transmit illegal information through obvious words and expressions. In social networks, users should be rational, keep their eyes open while holding a group to keep warm, and not be blinded by superficial information to prevent the infringement of criminals.

In today’s society full of alienation and social pressure, partner socialization provides a unique and beneficial way for some people to interact. We can’t let the behavior of a few abusers,And denyThe positive value of social interaction. Therefore, all sectors of society need to work together to protect the purity and legitimacy of partner socialization, and strive to ensure that partner socialization is not distorted as a tool for illegal transactions while meeting people’s social needs, so that partner culture can continue to radiate warmth and friendliness and bring positive energy to society.

After crouching

The high temperature in various places continues to spread.

Some people don’t pay attention to it after heatstroke.

Wait until after severe heatstroke

The tragedy is irreversible …

In the past week, the emergency department of Sandun Hospital of Zhejiang Hospital has received many cases of heatstroke every day. A 30-year-old female patient with heatstroke (severe heatstroke) did not turn on the air conditioner at home, and the electric fan was given to the child. By the time the family found out that she was not in the right condition, the patient had fallen into a deep coma.

What took you so long? Her husband explained that "she is not afraid of heat at ordinary times". In the end, the doctors tried their best, but there was nothing they could do.

The doctor stressed that heatstroke is severe heatstroke, and the mortality rate is very high if the rescue is not timely. However, heatstroke usually does not happen suddenly. If there is threatened heatstroke or mild heatstroke, we must intervene in time, otherwise the symptoms will continue to worsen, such as heatstroke and even death.

On the social platform, related topics also rushed to the hot search.

Netizens said

"Poor inherit the wind"

Some netizens don’t understand her husband’s words.

Xiao Bian reminds that in high temperature weather, whether in production or life, we should guard against the personal safety risks caused by summer heat.

Eight Mistakes of Heat Shock Disease

Misunderstanding 1

Heat stroke is heatstroke, so it is not life-threatening.

Heat stroke is the most serious type of severe heatstroke. Heat stroke is not as simple as raising body temperature, but produces a series of terrible physiological reactions. Patients will have multiple organ failure, central nervous system dysfunction, disseminated intravascular coagulation and so on. If it is not properly treated in time, the death rate of heat stroke is very high, and the general death rate can reach 50%-70%, and the death rate of elderly patients over 70 years old will reach 80%.

Myth 2

If you have symptoms of heatstroke, you can cool down at home.

Heatstroke is extremely dangerous once it develops to the stage of heatstroke. When the patient has symptoms of heatstroke such as high fever, no sweat, blurred consciousness, convulsion, or even no response, don’t hesitate to call 120 in time and send him to the hospital as soon as possible.

Misunderstanding 3

Indoor, there will be no heat stroke.

Heat stroke is not exclusive to outdoor, and indoor small environment with high temperature and poor ventilation may also cause heat stroke. Decoration workers and workshop workers who stay in a closed space for a long time belong to the high-risk group of heat stroke; Some elderly people live in old houses with poor ventilation and no air conditioning, and are also prone to heat stroke.

Misunderstanding 4

If you don’t do strenuous exercise, you won’t get heatstroke.

Heat stroke can be divided into labor type and non-labor type, the former refers to strenuous exercise in summer and high-intensity physical activity; The latter is common in the elderly, infants, pregnant women and other people with slightly weaker physique. In the summer of 2022, there was an incident in Shandong where a woman suffered from fever during the confinement period and eventually died of heatstroke.

Myth 5

If the temperature is not high, it is not heatstroke.

Elevated body temperature is the main feature of heatstroke, and the core body temperature of patients is mostly above 40℃. The core temperature mentioned here is often reflected by rectal temperature. Our daily measurement of axillary temperature or ear temperature can only be used as a reference, and can not be used as a basis for the diagnosis of heatstroke.

Myth 6

Only in summer will there be heatstroke.

Heat stroke is not exclusive to summer. For example, workers who work in unventilated high-temperature factories for a long time, firefighters who face raging fires, and even people who steam saunas in winter may suffer from heat stroke.

Misunderstanding 7

In hot weather, eating more cold drinks can prevent heatstroke.

The most important thing to prevent heatstroke is to drink plenty of water, including white water, salt water and drinks containing electrolytes such as potassium, sodium and chlorine. Eating a lot of cold drinks will increase the burden on the stomach. Alcoholic drinks and high-sugar drinks will make the body lose water and are not recommended.

Misunderstanding 8

Women with weak constitution are more likely to get heatstroke.

Generally speaking, women’s heat adaptability is weaker than men’s, but a large number of clinical data show that there are more men suffering from heat stroke than women, which should be related to men’s more outdoor work and heavy physical activities. Such as outdoor high-temperature workers, steel workers, firefighters, athletes, soldiers participating in training, etc. are all high-risk groups of heat stroke.

Diffusion reminds people around you

The heat is scorching

Be sure to watch out for heatstroke!

　　"Stand up straight and stride." Under the guidance of medical staff, Xiao Chen, a running friend, is conducting exercise treadmill experiments in Beijing Hejia Hospital. In the Beijing Half Marathon in April this year, Xiao Chen had a cardiac arrest. Fortunately, he was discovered by the volunteers of Hejia AED, and was successfully rescued through cardiopulmonary resuscitation and AED (External Automatic Defibrillation Transporter) electric defibrillation. After months of recovery, doctors need to re-evaluate his heart function.

　　The start of the 2019 Beijing Marathon is just around the corner, and even senior runners may "stumble" and face the great risk of sudden cardiac death.

　　Cardiology experts remind that six types of patients, such as those who have a history of myocardial infarction, those who have been diagnosed with heart diseases and have undergone surgery, and those who have a history of unexplained syncope, are generally not suitable for marathon. If you want your heart to be safe in high-intensity events, you need scientific cognition and pre-competition heart evaluation.

　　Senior runner’s cardiac arrest AED successfully rescued

　　"I was more excited when I finally sprinted. I shouted and rushed over. After a few steps, my feet were soft and I suddenly lost consciousness." Xiao Chen, a runner who suffered an accident in this year’s semi-Marseille in Beijing, said that he has ten years of long-distance running experience and participated in eight or nine marathons, which is a senior runner. I didn’t expect that this time he became the object of "first aid".

　　At that time, it was Yuan Tong, an emergency nurse in Beijing Hejia Hospital, one of the medical security units of Beijing Half Horse Race, who was present to defibrillate Chen Jinxing AED. She said that the timely discovery of the support staff and the skilled use of AED pulled Xiao Chen back from the death line, otherwise once the cardiac arrest was not treated for 4 to 6 minutes, the brain would be irreversibly damaged, and even if the heartbeat was restored, it might become a vegetative state.

　　Wang Dezhao, chief physician of the Department of Cardiology, Beijing Hejia Hospital, said that cardiovascular system accidents that often lead to cardiac arrest and sudden death in marathons are usually sudden acute myocardial infarction or malignant arrhythmia. Although the probability of occurrence is low, once it appears, it is the most dangerous. It is the most effective way to rescue patients with cardiac arrest and sudden death by using artificial chest compressions and AED defibrillation in the early stage. Beijing United Family Hospital is the official and exclusive designated medical service provider for Beijing Marathon. All AED volunteers have passed the cardiopulmonary resuscitation training organized by the American Heart Association (AHA) and obtained the certificates of Basic Life Support (BLS) and Advanced Life Support (ACLS), so they have the ability to find and rescue runners with cardiac arrest in the first time.

　　Six groups of people should have a heart evaluation before the game.

　　How to run a horse safely? Wang Dezhao said that runners must first have a clear understanding of their physical condition, and the following groups of people are not suitable for participating in such high-risk events.

　　First, patients who had a history of myocardial infarction in the past, especially 6 months after myocardial infarction; Followed by patients who have been diagnosed with angina pectoris, or have undergone coronary stenting, coronary artery bypass grafting and installed pacemakers; Third, it is a patient who has a history of unexplained syncope or has done electrical cardioversion; The fourth is patients with severe arrhythmia or taking antiarrhythmic drugs; In addition, patients with a history of congenital heart disease, cardiomyopathy or cardiovascular malformation, and patients with special ECG manifestations, such as Brugada syndrome, long QT syndrome and preexcitation syndrome (all three groups have special ECG manifestations), are not suitable for high-risk events similar to marathon.

　　In addition to people who are not suitable for horse racing, there are six groups of people who can participate in the marathon, but they need to be evaluated before the race. The first category is people with risk factors of coronary heart disease, including smoking, hypertension, diabetes, hyperlipidemia, family history of premature coronary heart disease (male < 55 years old, female < 65 years old), heavy drinking, sedentary, obesity, staying up late and working under great pressure; The second category is people with family history of sudden cardiac death; The third category is people who have had severe diarrhea or used diuretics recently, and it is very likely that there are abnormal levels of potassium, magnesium and calcium ions; The fourth category is people who have arrhythmia without drug treatment, including sinus arrhythmia, various premature beats, sinus bradycardia, etc. The fifth category is people who have had discomfort in the area below the jaw and above the umbilicus related to activities, or have palpitations and shortness of breath; The sixth category is people who are anxious, hypochondriac and have had a history of panic attacks. Most of these people do not have the typical symptoms of organic heart disease, but they belong to high-risk groups. If there is no heart assessment, there may be unexpected situations in extreme sports such as marathon.

　　Three types of heart assessment help runners stay away from accidents

　　Wang Dezhao introduced that marathon is an extreme sport with certain potential risks. However, as long as the heart function is scientifically evaluated before the game and the physical condition is known in advance, accidents such as cardiac arrest can be avoided to the maximum extent.

　　"If the heart is compared to a house, then it has three systems, including waterway system, circuit system and structural system." According to Wang Dezhao, heart evaluation is also divided into three categories according to three systems: the first category is the evaluation of the "waterway system" of the heart, and the "waterway system" refers to the blood vessels of the heart itself &mdash; &mdash; Coronary artery. If the runner has chest tightness, shortness of breath, chest pain, pressure, burning pain, pain in the left upper limb or left shoulder and back, which suggests that angina pectoris is possible, it should be evaluated by exercise treadmill test to observe whether the runner will have myocardial ischemia when he reaches the limit heart rate, which is also a simple and effective means to screen coronary heart disease. If the exercise treadmill test is abnormal, further coronary CTA or coronary angiography is needed.

　　The second kind of evaluation depends on the "circuit system" of the heart, that is, the evaluation of cardiac electrical activity. If the runner has palpitation, irregular heartbeat, too slow or too fast heartbeat, it suggests that the cardiac electrical activity is abnormal, and it is necessary to do ECG monitoring for 24 hours, 7 days, 1 month or even longer. By monitoring the ECG changes at the onset of symptoms, the disease can be diagnosed and whether it is suitable for the competition can be evaluated.

　　The third category is the evaluation of heart structure. If the runner has heart murmur, myocarditis, cardiomyopathy, congenital heart disease, etc., it is necessary to evaluate the morphological structure of the heart by heart color Doppler ultrasound. If you have serious structural heart disease, especially hypertrophic obstructive cardiomyopathy or aortic stenosis, you are not suitable for marathon.

　　How to predict and save yourself when you suddenly feel unwell in the game? Wang Dezhao said that first of all, runners should stop exercising, rest in a comfortable and relaxed posture, and seek help from medical staff; If the heartbeat suddenly accelerates, fast and even, it may be supraventricular tachycardia. You can hold your breath and cough hard, which may stop the tachycardia. If the pain in the chest or other suspicious parts (back, upper limbs, pharynx, etc.) persists, the attack of acute myocardial infarction cannot be ruled out. It is best to lie on your back, relax as much as possible, take a deep breath slowly and wait for rescue. (Reporter Chen Si)
