The model class introduced today is the most considered class when many people buy their first car, mainly because the size of this class is moderate and the price is reasonable. You must also have a look at this car, which will definitely bring you unexpected surprises.

Rene Liu (left) as Chen? Assistant debut, mentoring strong feelings.

Chen Guofu is currently the artistic director of Huayi Brothers Film Industry in the Mainland.

　　Ambiguous love

　　A few days ago, the reporter witnessed milk tea leaving Mucha’s residence alone. She wore a striped blouse and trousers to dress up casually, and went out with black-rimmed glasses. After staying in a building on Zhongxiao East Road in Taipei for nearly 2 hours, she took a taxi to the East District to pick up the "Glasses Man" and got on the bus. Two people went to a Japanese restaurant in Dunhua South Road Lane for dinner. Two hours later, they went out for a walk together. The reporter found that "Glasses Man" was the director Chen Guofu who had been having an affair with milk tea for more than 10 years. Later, the milk tea stopped the taxi, and two people went directly back to the milk tea residence. The boy got off the station at the roadside, and the milk tea paid the fare. Until 1 am, the reporter did not see Chen Guofu leave.

　　Liu said that he visited the studio.

　　On June 1 ST, milk tea took part in the "512 Caring Action in Performing Arts" in Hong Kong on her birthday, and the reporter finally got in touch with her. When Chen Guofu came into her house late at night, she generously said, "I rarely met the director after the performance of" Double Eyes ".I invited him out for dinner that day. He heard that I had spent a lot of time on the music studio, so I came to see it, not my home."

　　Enlightenment instructors have a close friendship.

　　As for not seeing the director leave late at night, she said that the director took a taxi later. Is there any progress for two people at present? She bluntly didn’t want to respond to this question, but stressed: "He was my first film director, and he won several awards, such as Asia-Pacific Best Actress and Academy Award Supporting Actress. He was an enlightenment mentor, with Zhang Jie,? Brother (Chen? ) The same is a good friend! "

　　She hasn’t had a birthday for many years, and she said happily that the benefit performance in Hong Kong on June 1st was the most meaningful birthday, but there were about eight artists backstage asking her to pay attention to her weight, so it was time to lose weight.

　　Four years ago, it was reported that Chen Guofu suffered from a liver tumor, and he was too ill to finish filming the film Happy Brothers. At that time, Milk Tea said that he would find time to visit him, but two years ago, someone asked Chen Guofu about her health, and she said that she had "little contact with Chen Guofu". It is reported that Chen Guofu lived alone in Beijing in recent years and only returned to Taiwan for one day at the end of May, but he happened to be witnessed by reporters having dinner with milk tea and staying at home for most of the day.

　　Chen pointed out that many people went to her house.

　　Chen Guofu is currently the artistic director of Huayi Brothers Film Industry in the Mainland. He responded yesterday: "It’s no secret that I have dinner with her. See how you handle it, hehe." The reporter asked, "But then you went into her house …?" He replied, "There are more people going to her house." And said: "I live in Beijing now, and it is quite difficult for everyone to meet. It is normal to meet and have a meal." However, he also said that he is in good health and work now. Thank you for your concern.

Extreme Yue and Extreme Krypton are owned by Geely, and their models are also produced in Geely’s vast SEA architecture. In this case, for many people, it is inevitable that the models of the two brands are positioned similarly. For example, the second model of Extreme Yue recently listed, some people think it is the version of Extreme Krypton 007.

Actually, it’s not! Extreme Yue 07 is different from Extreme Krypton 007 in terms of product positioning and product configuration. So, today, I’ll also give you an interpretation of the extreme yue 07 to see if it’s worth buying. Which configuration version should I choose to buy?

As for this car, I think it has some advantages compared with the more and more homogeneous new energy vehicles, such as "no one has me, no one has me". Among them, one of the great advantages is that it comes from Geely’s vast SEA architecture, so that the stability and drivability of the vehicle can be guaranteed. After all, we know that the vast architecture of SEA is the star architecture of the current new energy vehicle market, and the models built based on this architecture are strong enough to compete in the market. This is true except for Extreme Yue 07, Like Krypton 001, 007, etc.

Another big advantage is the advantage in intelligence. The title of "automobile robot" of Yuejie is not for nothing. Like the 07, Yuejie has a 35.6-inch super-large integrated screen, and the brand-new end-to-end perception model has been upgraded in terms of detection ability, tracking ability, mapping ability and scene understanding ability, and the voice assistant SIMO has also been upgraded, as well as the Qualcomm Snapdragon 8295P chip equipped in the whole system, all of which prove its intelligent interaction level to us.

There is also its intelligent driver assistance system, which has also been optimized, adding the curve AEB function, which can stop steadily even if the front car disappears. Extreme Yue 07 is also equipped with ASD Apollo advanced intelligent driving system. It is said that it will be able to drive all over the country before the end of this year, and it is still purely visual perception. This kind of intelligent driving ability is indeed leading enough.

In terms of batteries, all the high-end versions of Extreme Yue 07 use Kirin batteries from Contemporary Amperex Technology Co., Limited. The battery pack has bullet-proof coated armor from Chinese Academy of Sciences at the bottom, which can withstand 3.5 tons of static pressure. This battery has obvious advantages in safety and fast charging performance. For some users who are worried about battery problems, they can obviously put their hearts in their stomachs.

Having said that, which configuration version of Extreme Yue 07 is worth buying? Personally, I recommend the standard version or long battery life version of Extreme Yue 07. After all, the limited-time preferential price of the two models is 199,900 yuan, and the latter is 219,900 yuan, both of which are within the price range of about 200,000 yuan, and the standard configuration like Extreme Yue 07 is completely enough for our users. Of course, if you are really not short of money and want to experience more extreme speed and passion, the performance version of nearly 300,000 yuan is also a good choice.

Generally speaking, the product strength of Extreme Yue 07 is worthy of recognition. Although the brand voice is not high in the market at present, it is blessed by Geely and Baidu. I believe that it will get better and better in the future market, and Extreme Yue 07 will also be favored by many consumers.

Zebra consumes Ren Jianxin

At a time when all industries are seriously involved, no one can win.

On the evening of April 25th, Liangpin Shop, a leisure snack head enterprise, disclosed its annual report for 2023: it realized an operating income of 8.046 billion yuan and a net profit of 180 million yuan. In the case of periodic pressure, the basic disk is generally stabilized.

The first quarterly report of 2024 disclosed on the same day shows that the company’s operating income has returned to the growth track, with a year-on-year increase of 2.79% to 2.451 billion yuan. Because the terminal took the initiative to make profits, the company’s net profit returned to the mother decreased by 57.98% year-on-year to 62.4828 million yuan.

In the last two years, discount snacks have expanded wildly, and the terminal price war has been rolling; Online traffic transfer, a trick can no longer eat all over the sky; Coupled with the return of rational consumption concept. All this makes casual snack players have to re-examine themselves.

Good shops are not hiding anything. Dare to face up to their own problems and have made targeted adjustments one after another. The company does not fight a single-dimensional price war, and insists on actively participating in industry competition through innovation and differentiation, so that the business can return to valuable growth.

Don’t underestimate the difficulties, and don’t underestimate the resilience of this 18-year-old leisure snack leading enterprise.

Tear off the bandage to heal.

The trillion-dollar leisure snack market was not made in one day. Participants in the market should not only be KA, but also brand operators such as good shops and three squirrels, and discount snacks are not destined to be the end of the model.

The continuous innovation of models and channels can stimulate the innovation vitality of the whole industry and jointly expand the market, so that users can finally benefit.

As a leading enterprise in the industry, Liangpin Shop (603719.SH) admits that it is going through a relatively "painful" period. If it is only an explanation for investors, it can be attributed to the impact of discount snacks.

However, looking at the essence through the appearance, the good shop deeply realized that the root cause of the current pressure on the company’s performance is that the brand does not provide users with enough sense of value. Only by facing up to our own problems can we find targeted solutions.

Engaged in the leisure and snack industry for 18 years, the good shop knows that blindly rolling prices and fighting price wars will only affect the benign development of the whole industry.

The competition between enterprises is essentially the competition of supply chain. Only by improving the quality and efficiency of the supply chain can we really provide users with products with high quality and price ratio.

Different from the simple purchasing relationship between discount snacks and suppliers, Liangpin Shop, as a brand, dominates the whole industrial chain and controls the whole process of products from raw material planting and purchasing, product research and development to production and sales.

Therefore, discount snacks and good shops are completely different price logic, and the method of "squeezing water" from the supply chain is also completely different. For good shops, "squeezing water" is by no means an extreme squeeze on suppliers, but through lean management in cost control, production efficiency and commercial efficiency. It can make every supplier in the industrial chain become a participant, contributor and beneficiary of reducing costs and increasing efficiency.

Based on this, in November 2023, Liangpin Store launched the largest price adjustment since its establishment 17 years ago, with an average price reduction of 22% for more than 300 products, with the highest drop of 45%.

How can we reduce the price without degrading the quality?

Taking nuts as an example, in the past, good shops purchased products with specified specifications, and the high grade led to high procurement cost of raw materials. The company made adjustments to this. On the one hand, it incorporated the purchase of bulk nut raw materials into the supplier’s direct mining system, and at the same time changed the acquisition strategy. After the market unified mining, the raw materials were classified.

For example, Hawaiian fruit, the company has built a raw material base and used domestic Hawaiian fruit instead of imported raw materials. At the same time, raw materials with different specifications are used to produce different products such as canned, bagged and comprehensive nuts. By maximizing the use of raw materials, the price of each type of products has dropped by 5 to 10 yuan.

Light sweet dried mango is a very popular product in Liangpin Store. In the past, the company purchased mangoes from abroad and processed them at home, and it was inevitable that there would be a lot of losses when fresh fruits crossed the ocean. In 2023, the company supported suppliers to build factories overseas, and the raw materials were purchased and processed locally, thus reducing the total cost. As a result, the company’s 112g light sweet dried mango dropped from 16.9 yuan to 39.7 yuan/kg in 8.9 yuan, far lower than similar products of well-known Shangchao.

With the continuous deepening of the reform and innovation of the supply chain of each product line and the overall improvement of operating efficiency, the terminal price of products will definitely make users have a more obvious perception.

Gather advantages and seek growth

In the leisure snack industry, Liangpin Shop is the most balanced brand in online and offline development, which is also the biggest difference and advantage between it and competing products in the channel.

In 2023, there were 537 new stores in the four core provinces, and the total number of offline stores at the end of the period reached 3,293, a net increase of 67 over the same period of last year. In the whole year, the revenue from offline channels reached 4.294 billion yuan, up 4.02% year-on-year.

At the 2024 annual meeting of Liangpin Shop, Yang Yinfen, chairman and general manager of the company, particularly emphasized that the store is the most important channel for Liangpin Shop and the main position for brand promotion.

In the future, the improvement of store management and efficiency, updating and model optimization will still be the top priority of good shops. Yang Yinfen emphasized that all channels of the company should be based on the products and prices of stores, and all channels should be close to the products and prices of stores, and resolutely prevent involution from occurring internally.

Many users who often visit good shops have seen obvious changes. With the introduction of new models and new products, the store is younger and has a fireworks atmosphere. For stores in specific scenes, good shops introduce high-frequency consumer goods such as coffee and short-term insurance; Seasonal introduction of innovative sketches such as frozen products, sausages and baked sweet potatoes effectively increased the customer unit price and sales in the quarter.

For the operation of online traffic, good shops get rid of the single money-burning purchase of their peers, and rely on the advantages of their own offline stores to build diversified and unique models such as "city matrix live broadcast", "talent with goods" and "official number live broadcast".

Take a different road

No industry can only have low-end and low price, which can only bring "morbid", and ultimately the users will be damaged. Snacks are closely related to people’s daily life and health, especially so.

Nowadays, users’ consumption behavior is more and more rational, and the requirements for snack products are more demanding, which should be "delicious", "healthy" (light burden), "cost performance" and "emotional value". Only brands and products that can fully meet the needs of users will have long-term survival value.

As a brand owner and industrial chain owner, Liangpin Shop controls the whole chain of raw materials, product research and development, production, etc., and has the advantage of meeting the needs of users.

As early as the second half of 2023, good shops promoted product upgrading with "good raw materials, good formula and good taste" as the anchor point. From wild bamboo shoots with reduced salt and preservatives, non-fried 0 trans fatty acid crisp pancakes, 2.0 version of preserved plum with "nothing added", to toast with 0 preservatives and 60 days shelf life, these seemingly subtle changes all require long-term accumulation of brands to find the optimal solution in taste and health.

As one of the drafting units of General Requirements for Healthy Snacks, Liangpin Shop advocates the concept of "five reductions" (reducing salt, sugar, fat, oil and food additives), focusing on the two research and development directions of making products with pure natural and healthy ingredients and reducing additive products in the production process, so as to make the snack formula simpler and healthier with low burden.

Recently, Shanghai has been the first in China, taking the lead in trying out "nutrition selection" grading label in the beverage industry. ABCD is clearly printed on the packaging of drinks, and it is clear at a glance whether the products are healthy or not.

After the pilot project in Shanghai is completed and the experience is summed up, I believe this model will be further promoted to the whole country and eventually extended to the whole food industry. This is not only the consumer’s demand for a healthy diet, but also the general trend.

In the face of the general trend, enterprises can only take the lead if they plan ahead.

After 18 years of deep cultivation in the leisure snack industry, good shops have witnessed changes in the industry, experienced storms, and developed the physique of differentiated competition.

In 2019, it was tired of the endless price war in the industry. The company decisively jumped out of the Red Sea with low quality and low price competition, set off the banner of high-quality snacks, and embarked on a wave of independent market.

Nowadays, although it is under pressure periodically, the company always insists on high-end unshakable. Return to the initial intention of "the quality of conscience, everyone’s shop", and win users with "quality-price ratio" through the improvement of its own efficiency. Finally, walk out of the good shop’s own path.

　　[car home Information] According to Bloomberg News, IDG Capital is considering buying some shares of Chery Holding Group Co., Ltd. from existing shareholders at a price of RMB 7 billion. Chery Automobile Co., Ltd., a subsidiary of Chery Holding Group Co., Ltd., is planning to submit an initial public offering (IPO) application as soon as 2024, and may seek a valuation of 150 billion yuan. Some media have verified this rumor with Chery Holdings and Chery Automobile, and have not received a response yet.

　　IDG Capital, which was reportedly planning to buy shares in Chery Holding Group, took the lead in developing venture capital business in China since 1993. It is the earliest private equity investment institution rooted in China, focusing on science and technology, advanced manufacturing/new energy, consumption, health and other fields.

　　From January to November this year, Chery Automobile sold a total of 1,665,600 vehicles, up 47.8% year-on-year, exceeding last year’s total.

In a few days, Musk will celebrate his 53rd birthday, and there is evidence that he may be the father of 12 babies. Over the years, Musk has been contributing to the increase of the world’s population, and he has constantly called on human beings to have more children.

Bloomberg recently quoted people familiar with the matter as saying that earlier this year, the third child of American billionaire Musk and the female executive of the brain-computer interface technology company "Neural Connection" was born. According to media statistics, Musk has become the father of at least 12 children during his interaction with many women.

Neither Musk nor Chiris responded to this news.

Musk was born in South Africa on June 28th, 1971. According to media reports, the world’s richest man has been associated with at least four women.

Musk has had three marriages. In 2000, Musk got married for the first time. His wife, Justin Wilson, is a Canadian writer. Their marriage lasted eight years, during which they gave birth to six sons. Alexander, the first child, died unexpectedly at the age of 10 weeks, and then the couple gave birth to twins (Griffin Musk and Xavier Musk) and triplets (Kai, Saxon, Damia) in vitro, all boys.

In 2008, after the divorce, Musk shared the custody of the children with Justin Wilson.

Musk’s remaining two marriages are only related to one woman. In 2010, Musk married westworld actress talulah riley, and they divorced in 2012. In July 2013, the two remarried. In March 2016, the two divorced again.

There were no children in this marriage. Since then, Musk has never stepped into marriage, but the pace of having children has never stopped.

In May 2020, Musk gave birth to a son named X with Canadian singer Grimes. After they broke up, in 2022, Grimes gave birth to Musk’s daughter, nicknamed Y, through surrogacy.

During this period, Musk and Hivon Chiris also gave birth to two children. Chiris is a female executive of Musk’s "neural connection". A court document shows that Musk gave birth to twins with Chiris in November 2021. It is reported that the child was born in a test tube.

In 2023, walter isaacson, a biographer of Musk, confirmed that Musk and Grimes had a third child that had not been reported before. The child’s age has not been made public, and he is nicknamed Tau.

Earlier this year, Musk was exposed and quietly gave birth to a child with Chiris.

It is not clear how many children Musk has. According to public reports, there are 11 children who are still alive.

Musk had previously expressed concern about the decline in fertility rate around the world, especially in developed countries. In June this year, Musk said that the country was "going extinct" and called on everyone to have more children and avoid "population collapse". In addition, the Musk Foundation secretly subsidizes the American civil society organization "Encouraging Birth Movement", which is committed to encouraging birth at the economic and political levels.

Musk’s "population crisis theory" is not recognized by academic circles. According to the prediction of the United Nations, the world population will exceed the peak of 10 billion by 2100. It is generally believed in academic circles that after the world population reaches its peak, it will maintain a stable trend or decrease slowly, and there will be no so-called "population crisis" on the earth in the short term.

The first generation DM hybrid system: the starting point of domestic plug-in hybrid

As early as 2003, BYD began to invest manpower and material resources in the research and development of plug-in hybrid system, and five years later, it launched the first generation DM hybrid system, which was installed on BYD F3DM (officially listed on December 15th, 2008). The historical significance of BYD F3DM lies in:

1. The "plug-in hybrid system" was officially brought into the mainstream market of hybrid vehicles;Compared with the Great Wall and Geely mentioned earlier, BYD’s basic hybrid technology has basically never left the concept of "plug-in hybrid system", so at least in this technical decision, there are not too many detours;

2. The technical concept of a new dual-motor architecture is mass-produced;This sentence is difficult to understand, so let’s take a look at the technical characteristics of the first generation DM hybrid system.

The design concept of "the first generation DM hybrid system" is mainly energy-saving. Through the structure of double motors and single-speed reducer with a 1.0-liter self-priming three-cylinder engine, three driving modes are realized: pure electric, extended range, hybrid (including direct drive) and three driving modes. The structure of "the first generation DM hybrid system" belongs to the classic "P1P3 motor architecture";

The first generation DM hybrid system also has four basic driving modes:

Pure electric mode:The "engine" is not started, the "clutch" is disengaged, and the "drive motor" drives the vehicle;

Series mode (extended range mode):The "engine" starts to drive the "generator" to generate electricity and supply it to the "battery", and the "drive motor" drives the vehicle;

Parallel mode:The "engine" is started and the "clutch" is coupled. At this time, the "generator" and the "driving motor" do work at the same time to jointly drive the vehicle.

Kinetic energy recovery mode:The "clutch" is disconnected and the "drive motor" recovers kinetic energy.

In addition, the "first generation DM hybrid system" is a special working condition during cruising, and two cruising modes are also designed:

Cruise direct drive mode:Clutch coupling, engine direct-drive vehicle, generator and drive motor do not do work;

Cruise power generation mode:The engine is started, the generator generates electricity to charge the battery, and the clutch is combined to drive the vehicle, while the drive motor does not do work.

Working principle of the first generation DM hybrid system (moving picture)

The maximum power of the first generation DM hybrid system is 50kW for the engine, 25kW for the generator and 50kW for the drive motor. The whole system is matched with each other, and the power consumption of pure electricity is 16kWh/100km, and the fuel consumption of comprehensive working conditions is 2.7L/100km. Interestingly, although the "first generation DM hybrid system" is a plug-in hybrid system, it is the same as a pure electric vehicle.Equipped with fast charging interface, you can charge 50% in 10 minutes.

However, the "first generation DM hybrid system" is not without its shortcomings, such as:

1.　Poor transmission smoothness:Because the chain drive is adopted between the "output shaft" and the "main reducer", it has high cost, easy wear, poor transmission stability and extra vibration and noise;

2.　Low upper power limit:Moreover, due to the cost at that time, the two "motors" and "engines" were equipped with low power (when the power was sufficient, the maximum total power was about 80kW), and the acceleration time per 100 kilometers was 10.5s, so the power was weak. In addition, because the "drive motor" is directly connected to the "output shaft", the maximum speed is limited by the maximum speed of the "motor";

3.　High car price:BYD F3DM is about 80,000 more expensive than the fuel version.

I wonder if you can see the similarity between the two.

However, we have to deny the historical significance of the "First Generation DM Hybrid System". This hybrid architecture, which was earlier than the "Honda i-MMD Hybrid System" (listed in 2012), not only affects the future of BYD, but also is a milestone of the whole hybrid car industry. Moreover, the technical concept of the "First Generation DM Hybrid System" is still glowing up to now. In the "BYD DM-i Hybrid System" since then,

The second generation DM hybrid system: performance trend, 542 strategy

The main idea of "the first generation DM hybrid system" is energy saving, but in terms of power, it is really unacceptable to many consumers. Therefore, the "Second Generation DM Hybrid System" released in 2013 has embarked on another concept-Performance trend.

Schematic diagram of the second generation DM hybrid system (Tang DM 2015)

Since the concept has changed, the whole structure has been naturally adjusted: the strategy of using the motor has been changed from the original P1P3 motor structure to the combination of P3P4 motor structure, and the whole hybrid system is the combination of P3 motor +P4 motor+engine, so BYD’s "three engines and four wheels" powertrain was born.

Schematic diagram of the second generation DM hybrid system (Tang DM 2015)

Based on the structure of the second-generation DM hybrid system, its driving modes can be roughly divided into the following categories:

Pure electric mode:"Battery" power supply, "P3 motor" and "P4 motor" jointly drive the car;

Series mode (extended range mode):The "engine" drives the "P3 motor" to generate electricity through the power generation gear of the gearbox, and the "P4 motor" drives the vehicle, and more electricity is stored in the "battery". However, judging from the powertrain composition of the front axle,There is no "series mode" in the "second generation DM hybrid system"In addition, to enter the "series mode", several harsh conditions must be met:

1. The power is less than 5%;

2. The vehicle speed is less than 15km/h and kept for 5 seconds;

3. After entering the mode, the vehicle speed still cannot exceed 20km/h, otherwise it will exit.

Parallel mode:That is, the "engine" and the front and rear two "motors" work at the same time. In this mode, the effect of timely four-wheel drive is realized, but it can be subdivided into two states:

Driving power generation:The "engine" drives the "front wheel" through the "transmission" and drives the "P3 motor" to generate electricity, while the "P4 motor" adjusts the output power according to the working conditions. At this time, from the powertrain of the front axle, it is a mode of "engine direct drive";

Driving without generating electricity:The "engine" drives the "front wheel" through the "transmission" but does not generate electricity. The output power of the "P3 motor" and "P4 motor" is adjusted according to the working conditions only to ensure the strongest power.

Parking power generation:The "engine" drives the "P3 motor" to generate electricity through the "power generation gear" of the transmission.

The second-generation DM hybrid system is the BYD Qin DM (model 2014) for the first time. The power system of this vehicle consists of a 1.5Ti in-cylinder direct injection engine (maximum power of 113kW), a 6-speed dry powershift (DT35) and a P3 motor (peak power of 110kW), and the acceleration of 100 kilometers is 5.9 seconds.

BYD Tang DM(2015 model) with "542" printed under the A-pillar.

Since then, BYD has improved the "second-generation DM hybrid system", continued to increase the power, and installed this system on the "BYD Tang DM" (2015 model). The main changes are as follows:

1.　"Engine" upgrade:1.5T (maximum power 113kW) is upgraded to 2.0T (maximum power 151kW/320N·m)；);

2.　The "transmission" changed from "dry" to "wet";When the 6-speed dry "powershift" is replaced by the 6-speed wet "powershift", the sense of power interruption is further weakened, and the ability to adjust the efficient working area of the "engine" is enhanced;

3.　Add "P4 motor":Add a P4 motor with the same peak power (110kW) as P3 motor.

Tail logo of BYD Tang DM(2015 model)

The overweight "three-engine four-wheel drive" hybrid system can output nearly 400kW of power, and the comprehensive torque can reach 800N·m, which realizes the acceleration of SUV for 4.9 seconds. In order to intuitively let consumers know that "BYD Tang DM" (2015 model) can run for 5 seconds, so BYD directly put "『4.9s』" on the tail label of the car.

Working principle of the second generation DM hybrid system (moving picture)

But for the "second-generation DM hybrid system", the most deadly sentence is nothing more than "a dragon with electricity, a caterpillar without electricity". There are actually several reasons behind this sentence:

1.　Weak feed:As mentioned earlier, from the hybrid powertrain of the front axle, the "second generation DM hybrid system" has no "series mode", that is to say, there is no "P1 motor" or "P0 motor", and there is no "generator" with continuous power supply, so it is impossible to maintain the power for a long time. The power can’t be maintained, and oil will be used if there is no power, which also leads to the decline of fuel economy of the overall hybrid system;

2.　"P3 motor" has low efficiency in some working conditions:Because the P3 motor is located at the output shaft of the transmission, it does not accept the speed regulation of the transmission, but only adjusts the speed through the fixed reduction gear. Therefore, at high speed, the efficiency is low, and the torque provided to the wheels will also be drastically reduced. In addition, when the vehicle speed is low, the P3 motor is running at a low speed and cannot charge the battery with high power.

Let’s find fault together. See the difference?

However, the "second generation DM hybrid system" also has a milestone significance from the technical concept, which has made BYD’s."542 strategy"(5 stands for acceleration within 5 seconds per 100 kilometers, 4 stands for full-time electric four-wheel drive, and 2 stands for fuel consumption within 2 liters per 100 kilometers), and the hybrid technology is separated from the traditional logic of pure fuel saving, just as this series has always reminded everyone that "fuel saving is not the whole of hybrid car technology". In addition, the "second generation DM hybrid system" also laid a solid foundation for the "BYD DM-p hybrid system".

The Third Generation DM Hybrid System: Complementing Shortboards and Improving Performance

Time has come to 2018, and the BYD Tang DM equipped with the "third generation DM hybrid system" has been rejuvenated. From the architecture of the hybrid system, the "third generation DM hybrid system" inherits most of the characteristics of the "second generation DM hybrid system", but it also brings a big improvement.

Schematic diagram of the third generation DM hybrid system structure

That is, at the P0 position in the front section of the "engine", it was added."BSG motor"(P0 motor), this "BSG motor" with a maximum power of 25kW mainly plays several roles:

With the addition of P0 motor, series connection can be realized (theoretical state).

1. Feed functionBy realizing "series connection" in a small power range, the shortcomings of the "second generation DM hybrid system" are made up.

2. Start the "engine"When the "engine" is started, the "BSG motor" intervenes to increase the speed of the "engine" in advance, so as to avoid the ignition of the "engine" in the low-speed area with insufficient combustion and large vibration, and realize the rapid and smooth start and stop of the "engine";

3. Adjust the "engine" speedIn the process of shifting gears, BSG motor can adjust the "engine" to reach the specified speed, thus improving the shift smoothness during driving.

Byd Tang DM(2018 model)

In addition to P0 motor, the third generation DM hybrid system is also equipped with a more powerful P4 motor, which has been increased from the maximum power of the previous generation of 110 kW/250 N m to 180 kW/380 N m. Therefore, the acceleration of 100 kilometers has also been increased from the original 4.9 seconds to 4.3 seconds (BYD Tang DM is 4.5 seconds).

The third generation DM hybrid system has further become a family bucket.

Another major upgrade of the third-generation DM hybrid system is the electronic control system. Through the integration of motor and electronic control equipment, the high-voltage 3-in-1 technology and drive 3-in-1 technology are finally realized, which greatly improves the performance, reduces the weight and reduces the volume. In addition, in addition to the "three-engine four-wheel drive" with oversized cups, BYD also enriched the collocation of the "third-generation DM hybrid system", and introduced the combination of "two-engine four-wheel drive" (P0 motor +P4 motor) and "two-engine front drive" (P0 motor +P3 motor), which were installed on the "BYD Song MAX DM" and other vehicles.

BYD DM-p Hybrid System: Dual Platform Strategy

In June 2020, BYD released the dual-platform strategy of DM hybrid system, namely "DM-p" and "DM-i".

"p" means "『powerful』"Inherited the structural design concept of the second and third generation "DM hybrid system" that pursues power and speed, and meets the consumers who pursue speed;

"I" means "『intelligent』"It inherits the structural design concept of the first generation of "DM hybrid system" that pursues energy saving and high efficiency, and satisfies consumers who pursue car economy.

Among them, the "BYD DM-i hybrid system" has changed greatly from the first generation. We will start later. Let’s take a look at the "BYD DM-p hybrid system" with relatively small structural changes.

The first batch of Han DM equipped with DM-p (June DM(2020)

Since the previous generation has added the 25kW BSG motor, I personally think that the design of BYD DM-p hybrid system takes the optimization of 『NVH』 and ride comfort as the core goal of the upgrade. So we can see:

1. 7-speed powershift.Compared with the previous 6-speed "powershift", the speed ratio difference is reduced and the ride comfort is improved. At the same time, the "transmission" uses more "ball bearings" to replace the original "cone bearings", reducing the friction area and improving the noise;

2. Redesigned powertrainThe engine (1.5T or 2.0T) and the intake and exhaust system of BYD DM-p hybrid system have been optimized and upgraded. For example, the 1.5T engine optimizes the bearing bush to reduce the clearance and friction. At the same time, optimize the "chain" to reduce the noise caused by the "engine" driving the "BSG motor", and for example, put the "CRV valve" outside to reduce the noise caused by the pressure relief of the "supercharger".

Principle of BYD DM-p hybrid system (moving picture)

Of course, the working mode of BYD DM-p hybrid system is relatively complete. Take the structure of "three engines and four wheels" as an example, including:

Pure electric mode: Suitable for commuting in urban road conditions, with pure battery life up to 100km；;

Series mode: "Engine" and "generator" are connected in series to generate electricity, and "drive motor" drives them;

Parallel modeThe "engine" and "driving motor" are driven together, and the acceleration of 100 kilometers is 4.5 seconds;

Cruise modeThe "engine" drives and generates electricity, the expressway runs at a constant speed, and the "engine" drives in a high efficiency range, which not only ensures power but also realizes economy and fuel saving;

Kinetic energy recovery mode: The "engine" and the "motor" of the front and rear axles simultaneously recover kinetic energy.

One more thing to mention here, we can see that the model equipped with BYD DM-p hybrid system has been able to achieve a pure battery life of 100km (battery capacity of 21.5kWh), which is also a bright spot in the strategy of "BYD DM dual platform". So, I will take a good look at how many surprises BYD DM-i hybrid system has brought.

Byd DM-i hybrid system: a master, you are in self-research

If the design concept of the first-generation DM hybrid system is energy-saving and fuel-saving, then the BYD DM-i hybrid system is sublimated. By adding a high-power motor and a high-capacity battery, the engine becomes an auxiliary component of power, and finally the effect of "using more electricity and less oil" is achieved.

Schematic diagram of disassembly of BYD DM-i hybrid system

The biggest advantage of BYD DM-i hybrid system is not the complicated structure, but the core control systems such as engine control system, motor control system and battery management system have been independently developed, including but not limited to:

"Xiaoyun Engine":1.5L and 1.5Ti "special engines for plug and mix";

"EHS system":A "hybrid special transmission" that inherits the design concept of "first generation DM hybrid system";

"Blade battery":High discharge rate and flexible collocation of "hybrid special power blade battery".

Next, let’s take a look at these core components separately.

1. "Xiaoyun Engine": Born only for high efficiency.

At present, there are two types of "engines" in Xiaoyun series, which focus on economy respectively."1.5L Special Engine for Plug-in and Mixing"(hereinafter referred to as "1.5L engine") and high performance, configured on C-class "DM-i" models."1.5Ti special engine for plug and mix"(hereinafter referred to as "1.5Ti engine").

Showcase of Xiaoyun 1.5Ti plug-in hybrid engine

The "1.5Ti engine" has a "compression ratio" of 12.5. The technical highlight is that its "turbocharger" adopts a "variable cross-section" design, which enables the "turbocharger" to supercharge in a wider speed range, thus ensuring the supercharging effect at low speed and not affecting the exhaust pressure at high speed.

Showcase of Xiaoyun 1.5L plug-in hybrid engine

The "1.5L engine" can be said to be "the masterpiece of BYD in the field of hybrid engines", and it has truly been "born for electricity". Compared with the traditional "engine", its overall structure has been greatly adjusted, and finally it has achieved a thermal efficiency of 43.04%. Digging into its technical principle, we can see that:

Schematic diagram of variable valve timing technology

Atkinson cycle ("Miller cycle"):By delaying the closing time of the intake valve through the variable valve timing technology, the energy consumption of the compression stroke in the four-stroke is reduced, and the expansion stroke remains unchanged, so that the mixed gas can do more work, improve the utilization rate of the mixed gas energy and reduce the exhaust loss. This technology can be seen in many "hybrid engines", and most OEMs will call this cycle "Atkinson cycle". The story is in "Really?" Now the "Atkinson" of hybrid cars is fake? I have explained it in detail in the article, so I won’t go into details here;

Conceptual diagram of compression ratio

15.5 Superhigh "Compression Ratio":Generally speaking, we think that the greater the compression ratio, the more work the engine does (that is, the greater the compression ratio, the higher the efficiency of the engine). The "1.5L engine" is designed with an ultra-high "compression ratio" of 15.5: 1, which also reflects its goal of efficiency first. Of course, as far as the compression ratio is concerned, BYD’s Xiaoyun Engine is definitely the best in the industry.

Schematic diagram of EGR valve working principle

Efficient "EGR" technology:In order to improve the overall efficiency of the "engine", an efficient "exhaust gas recirculation system" is essential. By optimizing the "exhaust gas recirculation system", BYD has increased the "EGR rate" to 25%, reducing the intake loss of the "engine" under medium and low load conditions, and also reducing the emission of nitrogen oxides. The "low-pressure water-cooled EGR technology" of Geely’s "Hybrid Special Engine" ("DHE15") mentioned earlier has the same technical logic;

Hybrid special engine after slimming

Cancel the traditional "gear train" and adopt "split cooling technology";Compared with the traditional engine, the biggest change of the 1.5L engine is to cancel the gear train of the engine, including the mechanical compressor, mechanical vacuum pump, mechanical steering booster pump and mechanical water pump. But for the sake of efficiency, the electric water pump is combined with the electronic double thermostat to realize the separate cooling of the cylinder block and the cylinder head.

Showcase of two Xiaoyun plug-in hybrid engines

Generally speaking, this "1.5L engine" (peak power 81kW/ peak torque 135N·m) aiming at hybrid efficiency has achieved the goal of 43.04% thermal efficiency theoretically through many technical optimizations such as 15.5 ultra-high compression ratio, Atkinson cycle, efficient EGR, low friction and cancellation of traditional gear train.

2. "EHS system": the core of BYD DM-i hybrid system

After talking about Xiaoyun Engine, there is another core of BYD DM-i Hybrid System: Hybrid Special Transmission, which BYD calls EHS System or E-CVT.

The structure of "EHS system" is "series-parallel double motors" structure, and its working principle inherits the design concept of "first generation DM hybrid system" with "electric drive as the center" and has been carried out.Overall optimization：

1. Different from the first-generation DM hybrid system, BYD DM-i hybrid system juxtaposes two high-speed motors that can reach 16,000 rpm, thus reducing the volume of the whole hybrid special transmission by about 30% and the weight by about 30%;

2. The "engine" is directly connected to the "generator" (P1 motor or ISG motor), connected to the "reduction gear" through the "clutch", and finally goes to the "output shaft". The "drive motor" (P3 motor) directly passes through the "reduction gear", and finally "power" also flows to the "output shaft", which is more efficient and fuel-efficient.

Schematic diagram of EHS system structure

According to the power of the drive motor, the current EHS system consists of three versions:

· 「EHS132」：The peak power of "generator" is 75kW, and that of "driving motor" is 132kW；;

· 「EHS145」：The peak power of "generator" is 75kW, and that of "driving motor" is 145kW；;

· 「EHS160」：The peak power of "generator" is 90kW, and that of "driving motor" is 160kW.

When the three EHS systems are adapted to the vehicle models, different Xiaoyun engines will be adopted:

"EHS 132" and "EHS145" adopt 1.5L "Xiaoyun Engine";

EHS 160 adopts Xiaoyun 1.5Ti Xiaoyun Engine.

Schematic diagram of working principle of BYD DM-i hybrid system (moving picture)

And "BYD DM-i hybrid system" also has the common working mode of hybrid system:

Pure electric mode:When starting and driving at low speed, the "drive motor" is powered by the "battery" to drive the vehicle;

Series mode:The "engine" drives the "generator" to generate electricity, and the electric energy is output to the "driving motor" through "electronic control" to directly drive the "wheels". When driving at low or medium speed or accelerating, if the "SOC value" is high, the vehicle control strategy will switch the drive to pure electric mode and stop the "engine". If the SOC value is low, the control strategy will make the engine work in the best efficiency area of oil consumption, and at the same time, the surplus energy will be converted into electric energy through the generator and temporarily stored in the battery, so that it is not easy to lose electricity under all working conditions.

Parallel mode:When the driving power demand of the whole vehicle is relatively high (such as overtaking at high speed or driving at ultra-high speed), the "engine" will be out of economic power, and at this time, the control system will let the "battery" intervene at an appropriate time to provide electric energy to the "drive motor" and form a parallel mode with the "engine";

Kinetic energy recovery mode:When braking, kinetic energy is recovered by "driving motor";

Engine direct drive mode:When cruising at high speed, the power of the engine is directly applied to the wheels through the clutch module in the EHS system, so that the engine is locked in the high-efficiency area. At the same time, in order to avoid the waste of the energy of the engine, the generator and the driving motor are on standby at any time, and when the power of the engine is surplus, they intervene in time to convert the energy into electric energy and store it in.

Schematic diagram of BYD flat wire motor

As mentioned earlier, from the complexity of structure and working principle, the "EHS system" may not be so amazing, but there are several key technologies behind this system, including but not limited to:

"Flat wire motor":The "motor" in "EHS system" adopts flat wire winding technology. According to official data, the highest efficiency of "motor" reaches 97.5%, the rated power is increased by 32%, the high-efficiency interval (the interval with efficiency greater than 90%) accounts for 90.3%, and the mass power density reaches 5.8 kW/kg.

The fourth generation "IGBT system" developed by ourselves;According to official data, the comprehensive efficiency of BYD’s "electronic control" is as high as 98.5%, and the "electronic control" high-efficiency area (that is, the area where the "electronic control" efficiency exceeds 90%) accounts for as high as 93%, which greatly reduces the loss of electronic control and improves efficiency.

Schematic diagram of manufacturing process of BYD’s fourth generation IGBT (moving picture)

Generally speaking, the core of EHS system is to make the engine focus on the best efficiency range and play more role as the motor.

3. "Blade Battery": BYD’s wayward capital

According to the official news, the blade battery used in BYD DM-i hybrid system should be slightly different from the blade battery used in pure electric vehicles. The official name is "hybrid special power blade battery", which makes me sigh that the main engine factory that can make its own battery is qualified for willfulness, and its special features are as follows:

Schematic diagram of BYD blade battery

The voltage of a single "battery" reaches 20V;Each battery is connected in series with several (presumably 6) soft package winding batteries, so that the voltage of a single battery can reach more than 20V, ensuring that the battery can still have enough voltage to ensure the driving efficiency of the motor when the power is low.

"Battery pack" can be flexibly matched:A single "battery pack" consists of 10 to 20 "blade batteries", in other words, the power will be between 8.3 and 21.5 kWh, that is, the theoretical pure battery life can be set between 50 and 120 km. Therefore, BYD can match "battery packs" with different capacities on different levels of vehicles;

Simplified structure and high space utilization;This is actually the common feature of BYD’s blade batteries. For example, the batteries are arranged vertically, so that the sampling wires, wires and data wires of the batteries can be placed on one side, thus reducing the structural complexity and improving the unit energy density of the battery pack.

Longitudinal arrangement of hybrid special power blade batteries

Of course, the analysis of the characteristics of other "blade batteries", such as the "discharge rate" and secondary packaging technology of "batteries", will not be expanded here, and we will open a separate article to explain it in detail. In a word, "blade battery" is as important as "Xiaoyun engine" and "EHS system" for the whole BYD DM-i hybrid system, which is indispensable and extremely important.

Byd Qin plus DM-i equipped with BYD DM-I hybrid system

To sum up the BYD DM-i hybrid system in one sentence, I think it can be said as follows:A self-developed hybrid system based on electricity has three core hybrid technologies and four main hybrid modes to create a driving experience with low fuel consumption and high comfort.

With the appearance of many models equipped with "BYD DM-i hybrid system", it is believed that the sales of BYD DM models will increase steadily.

The beginning of recycling: an overview of the technical route of BYD DM hybrid system

When we review the course of BYD’s DM hybrid system, we will find that BYD’s DM dual-platform strategy is a staged victory after nearly 20 years of technology accumulation:

Architectural changes of BYD DM hybrid system in past dynasties (moving picture)

Finally, I summarized the basic parameters and architecture of each generation of "DM hybrid system", and summarized the characteristics and historical significance of each generation:

Parameters & Architecture of the First Generation DM Hybrid System (for reference only)

The "first generation DM hybrid system" determined the hybrid architecture with the design concept of fuel economy, but it failed to open the market due to the factors of "engine", "three power" technology and manufacturing cost at that time. It should be said that the historical significance of the "first generation DM hybrid system" is greater than its market significance.

Parameters & Architecture of the Second Generation DM Hybrid System (for reference only)

The "second generation DM hybrid system" is an attempt by BYD to build a "high-performance hybrid system". Although there are obvious problems in energy consumption and feed capacity, it has raised the upper limit of the performance of this price hybrid model, which has strong industrial significance.

Parameters & Architecture of the Third Generation DM Hybrid System (for reference only)

With the continuous improvement of BYD’s technology in "Three Electricity", the practicability of "the third generation DM hybrid system" has been greatly improved, especially the hybrid solution with high-power "BSG motor", which has surprised many colleagues.

Parameters & Architecture of BYD DM-p Hybrid System (for reference only)

The BYD DM-p hybrid system is a milestone of BYD’s phased solidification of the "three motors+powershift" hybrid scheme. Under the two technical guarantees of "high power motor+large capacity battery", the vehicles equipped with BYD DM-p hybrid system have made another qualitative leap in NVH, power switching smoothness and energy consumption.

Byd DM-i hybrid system parameters & architecture (for reference only)

Of course, "BYD DM-i hybrid system" is the trump card of BYD in the field of hybrid technology at present, and its economy and practicality are self-evident. As summarized before, the most valuable point of BYD DM-i hybrid system is that BYD has the ability to develop and manufacture key components such as battery, electronic control and electronic control chip.

Parameter list of BYD DM hybrid system in past dynasties (for reference only)

If you want to ask me: "Is the current BYD DM hybrid system good? My answer is: After nearly 20 years of development, BYD DM Hybrid System has developed into a school of its own in terms of technology and production, and it is quite mature. As for whether to recommend people to buy it, I still have those two sentences:
