What are the deputies concerned about?

Jinhua, Zhejiang: Please comment on the semi-annual report of procuratorial work on the spot on behalf of members.

Deputy Yu Xuewen

Representative Huang Meimei

Representative Fang Qing

Commissioner Liu Huaying.

Representative Wu Yuexiao

"The semi-annual report is very bright! I am very satisfied with Jinhua’s procuratorial work! " "The work of less arrest and cautious prosecution highlights the judicial temperature and maintains social harmony and stability, which is worthy of praise!" "The unchecked work should also increase publicity!" "Intellectual property protection should be good at leveraging!"……On August 2, the Procuratorate of Jinhua City, Zhejiang Province held a press conference. In addition to media reporters, the press conference also invited representatives of the national, provincial and municipal people’s congresses and members of Jinhua CPPCC. After listening to the briefing on the work of the hospital in the first half of the year, five deputies made comments and suggestions respectively.

Less arrest, more caution and more caution.

In order to strictly implement the criminal policy of less arrest and cautious prosecution and cautious detention, in mid-March this year, Jinhua City Procuratorate and the public security organs jointly issued the Guiding Opinions on Reducing Criminal Compulsory Measures in Custody (Trial), clarifying the application scope, standards and scales of compulsory measures, and establishing relevant supporting mechanisms to reduce coercive measures in custody. After the guidance was issued, the pretrial detention rate in the first half of the city decreased by 12.92% year-on-year, and showed a downward trend month by month.

"It is not only an expression of the modesty of the law, but also an effective measure to develop the’ Fengqiao experience’ in the new era. Procuratorial organs should standardize the use of the right not to approve arrest and the right not to appeal, and also perform their supervisory functions, strengthen supervision over this work, and strive to ensure fairness and justice." Yu Xuewen, deputy to the National People’s Congress, director of the village committee of Qingkeng Village, Liucheng She Town, Wuyi County, Zhejiang Province, and chairman of Zhejiang Gengxiang Organic Tea Industry (Base) Development Co., Ltd., took the lead in expressing his views on this highlight.

"It is the judicial policy of the country to arrest juvenile criminal suspects with less caution, which reflects the judicial temperature. Let the minors and parents involved in the crime understand this!" Combined with her case of participating in the procuratorial organs’ assistance and education for minors involved in crimes, Huang Meimei, a deputy to the National People’s Congress and an employee of the comprehensive department of Daoming Optics Co., Ltd., suggested that when carrying out the procuratorial work for minors, the word "caution" should be emphasized, and it is neither possible to arrest them at once nor to let them go at once. We should really make good use of this policy to save minors involved in crimes, but also prevent "deep love" from being abused.

"Help me 885"

"In terms of technology, combined with the key areas and key issues involved in the unchecked work, it is necessary to better achieve the smooth flow and feedback of front desk services and report reception and background clues; In terms of mechanism construction, it is necessary to implement the "two numbers and one yard" mechanism linked by multiple departments; In terms of publicity, in addition to being rolled out on campus, it should be extended to hospitals, education and training institutions, township streets and other places that are in close contact with minors, and the mandatory reporting system should be fully implemented to ensure all-round protection of minors. " Focusing on the procuratorial work of minors, Fang Qing, deputy of Zhejiang Provincial People’s Congress, vice chairman of Jinhua Municipal Committee of the Chinese Revolutionary Committee and principal of Jinhua jindong district Experimental Primary School, put forward three suggestions in one breath.

"Two numbers and one yard" refers to the special number of "88908585" minors’ protection telephone, "Help me 885" WeChat official account and the two-dimensional code for minors’ protection. It is the "885 Jinhua minors’ protection linkage platform" created by Jinhua Municipal Bureau of Letters and Calls, Women’s Federation, Education Bureau and Civil Affairs Bureau. The platform creates a "six-in-one" minor protection pattern of family, school, society, network, government and justice, and provides services such as legal publicity, legal consultation, family education guidance, complaints and reports, and assistance for children in distress, covering all aspects of minor work. Since it was put into operation in mid-April, "Help Me 885" WeChat official account has attracted nearly 70,000 users’ attention, and has received and sorted out more than 20 case clues.

"The procuratorial organs have put a lot of effort into the construction of this platform." "With the implementation of the’ two laws’ for minors, the protection of minors needs the joint efforts of the whole society." "We must constantly optimize and upgrade the platform, strengthen linkage, and let more people participate."……The deputies spoke in succession.

Protect the legitimate rights and interests of enterprises

Corporate protection has also become the focus of the deputies. Yu Xuewen suggested that the procuratorial organs should strengthen the legal supervision of enterprise-related cases and give full play to the functions of protest to protect the legitimate rights and interests of enterprises.

Liu Huaying, a member of Jinhua CPPCC and a partner of Guofeng Law Firm, suggested strengthening the protection of intellectual property rights in an all-round way, advising the court to apply restraining orders and occupational bans to defendants who have infringed on intellectual property rights for a long time, paying continuous attention to the new situation of intellectual property crimes committed by relying on the Internet, continuing to participate in social governance and extending procuratorial functions.

Ding Chengyi, director of the Political Department of Jinhua City Procuratorate, said that since the beginning of this year, the institute has made every effort to ensure the construction of a national innovative city, and actively escorted the development of major projects such as Jinyi Free Trade Zone and China-Europe (Yixin Europe) trains, especially strengthened the protection of intellectual property rights of enterprises, such as sinking a platform for protecting intellectual property rights, building a closed-loop judicial protection chain for intellectual property rights, and carrying out a series of activities such as escorting private entrepreneurs to develop the private economy.

Wu Yuexiao, member of the Judicial Supervision Committee of the Standing Committee of Jinhua Municipal People’s Congress and general manager of Jinzi Ham Co., Ltd., pointed out that while protecting the development of private economy, procuratorial organs should strengthen supervision and management of rights protection, protect the legitimate rights and interests of vulnerable groups and promote social harmony and stability. According to reports, in the first half of this year, Jinhua City Procuratorate safeguarded the legitimate rights and interests of vulnerable groups, launched a special campaign to help solve the problem of wage arrears, and actively communicated with the municipal social security department to obtain more than 1,400 clues about wage arrears.

The press conference also informed the city’s procuratorial organs of "doing a good job in mass letters and visits and responding to mass letters and visits": in the first half of this year, the city’s procuratorial organs accepted a total of 2,186 mass letters and visits, all of which met the requirements for reply were procedural within 7 days and 100% response to the handling process or results within 3 months, while strengthening leadership package and resolving accumulated cases. The deputies pointed out that major, difficult and complicated letters and visits should be followed up properly after the visit, and more ways should be used to explain the law, such as leadership interviews, joint visits by departments, and public hearings. It is necessary to establish an all-weather rapid response mechanism based on the 12309 procuratorial service center platform.

1905 movie network news On May 16th, French local time, the promotion meeting of the 2nd Pingyao International Film Festival was held during the Cannes Film Festival. Director Jia Zhangke, actors Zhao Tao, Xú Zhēng, Huang Xiaoming and artistic director Marco Müller all made their appearances.

The theme of the second Pingyao Film Festival was established and the bonus amount was increased.

Jia Zhangke and Marco Müller announced the theme of the new film festival as — — Movies are back in the market. The reason for choosing this theme is to "let the audience experience the soil when the film was first produced, the connection between the film and the public and daily life, and let everyone return to the familiar market feeling in the setting and atmosphere of the film festival."

Like last year, this year’s film festival will continue to set up the premiere units of Crouching Tiger, Hidden Dragon and Red Carpet, among which the highlight is the Chinese new generation unit. In addition, a special retrospective exhibition of Russian New Wave films will be held, which will be shown on the world’s first films directed in the 1960s and 1970s. All these films have been restored in 4K.

Most notably, the second Pingyao Film Festival increased the amount of prize money, and the best film will receive 20,000 US dollars, half of which will be given to the director and the other half to encourage China publishers. Marco Müller said that the film selection level will be higher than last year, and revealed that the film list will be released in mid-September.

Xú Zhēng didn’t read the whole script before talking about filming.

Xú Zhēng, one of the actors in Children of the Rivers and Lakes, plays the second man in Zhao Tao in the Three Gorges part of the film. When talking about appearing in this play, he said, "The director is just stimulating me. He doesn’t tell me who other people are playing, what their role is, or the whole story. He just said that you should behave well."

When asked about his feelings during filming, Xú Zhēng said, "I think it is particularly interesting. The first scene stood on the platform with Mr. Zhao Tao. When I saw the director, I had a feeling of crossing the times, like returning to Jia Zhangke’s previous works. It was wonderful."

The mainstream car has a moderate size, which can meet all needs well, and the price of the mainstream car is also reasonable, so it is right to buy it! Domestic cars have always been concerned, and today is one of them. Now let’s follow Xiaobian to see what it has done.

Let’s take a look at the appearance of Starway Chasing the Wind. The front face of Starway Chasing the Wind presents a simple design style and is equipped with a layered air intake grille, which looks sporty. Headlights are very in line with the aesthetics of consumers, and the overall look has a certain sense of hierarchy. The car is equipped with LED daytime running lights, delayed shutdown and so on. Coming to the side of the car, the size of the car body is 4538MM*1848MM*1699MM, and the car adopts fashionable and simple lines, which gives people a very calm feeling. With large-sized thick-walled tires, it gives people a very deep feeling. In terms of the rear end, the tail line of Starway Chasing the Wind is comfortable, and the taillights give people a very soft feeling. The layout of the exhaust pipe uses a bilateral double-out shape, which is neat and vivid.

Sitting in the car, the interior adopts a full design, which is very simple and generous. The steering wheel of the car is very simple in shape and made of leather, giving a good grip experience. From the central control point of view, the car decoration has a steady touch-control LCD central control screen, which makes the interior style impressive and gives people a feeling full of exquisiteness. Let’s take a look at the dashboard and seats again, which are very eye-catching. The car adopts imitation leather seats, which are wrapped in place and have good overall comfort.

Starway Chasing Wind matches CVT gearbox, with an acceleration time of 9.7s per 100 kilometers, which has good power performance and is completely OK for daily use.

The car is equipped with remote control key, rear wiper, interior ambience light, traction control (ASR/TCS, etc.), CarPlay support and other configurations, and the configuration performance is quite good, giving drivers and passengers a comfortable car experience.

Summary of the full text: Many people buy SUVs because of its stronger passability. The car is practical and fully equipped, and it is a good helper for home travel.

Recently, Song Joong Ki’s newly photographed pictorial was exposed. Even in the fine retouching, it is not difficult to see that his temperament has changed greatly and he no longer has a sense of youth. The whole person looks very strong, and netizens can’t help but sigh: Time makes people old, and stars can’t resist being fat and ruining everything. In the past, the male god was old!

Song Joong Ki, who was 35 years old, was once one of the most popular male gods in Asia, among which his feelings with Song Hye Kyo attracted much attention. From the TV screen CP to the real love, marriage and then to the end of breaking up, the CP powder of Shuangsong is like riding a roller coaster.

As an actor, almost all of Song Joong Ki’s works can be called masterpieces, such as Sungkyunkwan Gossip, Wolf Boy, Kind Man and Descendants of the Sun. He constantly breaks through himself and tries to challenge different roles, and he is definitely an acting school in acting. Unfortunately, the most brilliant moment in Song Joong Ki’s acting career is not his acting skills, but his life. This is probably the saddest thing for an actor. Private life overshadows his career, which should be the biggest blow to the actor.

After military service, Song Joong Ki was lucky enough to be chosen as the leading actor partner Song Hye Kyo to shoot Descendants of the Sun, which was simply the highlight moment of Song Joong Ki. With Descendants of the Sun, Song Joong Ki not only successfully reached the top of the mountain and won many awards, but also successfully won the famous foreign beauty Song Hye Kyo. Song Joong Ki and Song Hye Kyo were caught off guard by the drama, and they skipped the announcement of their relationship and announced their marriage directly. The rapid progress of Shuangsong CP really shocked fans and netizens, and everyone sent their blessings without stint. Then they made low-key preparations for the wedding and got married. The once double-song CP was really Bai Yueguang in many people’s minds.

But love came and went quickly, and Song Hye Kyo, who got married soon, returned to film Boyfriend with Park Bo Gum. Perhaps it’s because the love of handsome men and beautiful women in the play makes everyone unable to extricate themselves, or it’s possible that netizens know that Song Hye Kyo is very easy to have an affair with actors because of the play. Soon after the play was broadcast, Song Hye Kyo had an affair with Park Bo Gum, knowing that it was getting worse and worse, and then the rumors of the marriage between the two Song couples were rampant.

The news spread for a long time and naturally became true. Sure enough, the Shuangsong couple broke up. At first, Song Joong Ki would clarify the scandal between Song Hye Kyo and Park Bo Gum, but over time, Song Joong Ki and Song Hye Kyo had no interaction. Maybe both of them don’t love each other, or maybe a person’s heart is broken. When Song Joong Ki announced his breakup, he was as decisive as when he announced his marriage. He directly issued a unilateral notice to announce his breakup, and the wording was so decisive and decisive, as if he had no nostalgia for his past lover. In this way, the love story of Shuangsong only lasted for just over a year.

The marriage between the two did not end so gracefully, and the two sides even went to court and completely tore their faces. Judging from their simple marriage, Song Joong Ki is obviously the one who loves more, and judging from the breakup, he is also the one who is hurt more. The past has gone with the wind, and even though both of them were unhappy when they broke up, life still needs to go on.

After breaking up, Song Joong Ki seems to have given up the body management, with a big figure and a fat face, and her sense of youth was gone overnight. Obesity makes him look rather greasy, and even fans can’t help but sigh: The young man who once had cream muscles and risorius has become a greasy uncle!

It is a compact SUV owned by BYD. At present, only the fuel version with 1.5T engine is on sale. The biggest change of DM-i equipped with BYD DM-i super hybrid technology lies in the power system. The use of a new plug-in hybrid system enables the new car to achieve a better balance between fuel consumption and power level.

The brand-new Dragon Face 3.0 design of BYD family is adopted, the front air intake grille is hexagonal, and the middle net adopts array design. The chrome-plated decorative strip running through the front of the car is connected with the LED headlights on both sides, and the upturned eyebrow shape and the large mouth front air intake grille show the dragon face. Daytime running lights are designed in the form of horizontal bars, which are arranged at the heat dissipation openings on both sides of the front enclosure, thus enhancing the overall momentum of the vehicle.

The arc of the roof is very beautiful, and it is matched with a layered waistline design to create a strong sense of movement. The car offers a variety of rim specifications and styles to meet the needs of different consumers. The red brake calipers reflect the fashionable and dynamic modeling concept of the car.

In the rear part, the new car adopts penetrating LED taillights and chrome-plated decorative strips, which greatly enhances the visual width of the rear. The small spoiler at the end of the roof and the silver rear diffuser around it create a very sporty feeling for the new car. In terms of body size, the length, width and height of the new car are 4705/1890/1680mm and the wheelbase is 2765mm respectively.

In terms of interior, the new car adopts a symmetrical central control design, and the air-conditioning outlets on both sides have a sense of design. A bright black decorative panel is also used in front of the co-driver to enhance the sense of luxury. The new car uses a 12.3-inch full LCD instrument and a 12.8-inch rotatable central control multimedia touch screen, and is also equipped with a three-spoke multi-function steering wheel and a lever electronic shift mechanism.

DM-i has two versions with pure battery life of 51km or 110km. The 51km endurance version has an acceleration time of 8.5s at 0-100km/h and a fuel consumption of 4.4L/100km, and the comprehensive endurance can reach 1150km with full fuel and electricity. The 110km battery life version has an acceleration time of 7.9s at 0-100km/h, a fuel consumption of 4.5L/100km, and a comprehensive battery life of 1,200km with full fuel and electricity.

In recent years, a very popular word has appeared: intellectual love.

Contemporary young people’s preferences have evolved from lust and ignorance to high IQ, and the love impulse dominated by intelligence has become the new mainstream of fashion. For young people who are at the forefront of the times, the pronoun of sexiness has long been separated from the body to the mind and brain, which was predicted by irene adler’s famous words in the English drama Sherlock Holmes ten years ago.

“Brainy is the New Sexy.”

Due to the high prosperity of civilization and economy, the orientation of human beings has changed from physical desire to intellectual desire, which is naturally not only reflected in mate selection. In the face of any multiple-choice questions, contemporary young people seem to be inclined to intelligence without hesitation. In the past, their parents’ hobbies for vehicles: massiness, sense of volume, resistance to construction and collision, are no longer core advantages, but intelligence, texture, beauty and sexiness.

Especially in the era of new energy, the intelligence of car brains has almost become an important indicator for them to subjectively judge whether a car is good or not.

To talk about intelligence, we can’t just talk about the wisdom of the car, but about the intelligent experience, the interaction in the cockpit, the knee-jerk reaction of AI, the ecological network brought by the interconnection, the integrity of the intelligent driving scheme, how awesome the radar and algorithm are, the emergency plan behind the automatic driving, the ability of the extrasensory system, and the deepening of the judgment of the whole scene. We must talk about Aouita 12.

Aouita’s cleverness is the superposition of multiple dimensions. The underlying logic is the hardware IQ of configuring the top case and its super execution, and the product EQ and its full emotional value, which are projected on the actual experience as intelligent experience and smart driving.

First of all, the AVATRUST extrasensory system in Aouita is the intuitive realization of IQ benchmark value. The whole system comes standard with 29 intelligent driving sensors, including 3 laser radars, 3 millimeter-wave radars, 11 high-definition cameras and 12 ultrasonic radars. From the data, the friends of the same level are severely hanged. For example, the extremely krypton 001 and even the more expensive Weilai et7 are only 7 cameras in hardware collocation. No matter how OTA, the factory configuration of Qingbei at birth has already made Aouita 12 from.

Intelligent driving NCA that doesn’t rely on high-precision maps is just like learning to draw inferences by formulas without relying on sea tactics. When other people’s intelligent driving needs to be calibrated, Aouita 12 has gradually realized the navigation ability of full scene coverage including main scene and refined scene. NCA can automatically identify traffic lights, automatically choose lanes according to navigation routes, take the initiative to avoid pedestrians and non-motor vehicles, and flexibly handle road conditions at unprotected intersections in cities. It can realize the functions of occupying roads to avoid obstacles, getting out of trouble and changing lanes, turning around at intersections, passing around the island, etc. The refined scenes cover traffic cone identification and avoidance, large-scale special-shaped vehicle perception, lane risk avoidance, detection of faulty vehicles driving slightly to the left to avoid, and blocking roads to prevent queue jumping and following cars.

It is equivalent to realizing the driving experience of old drivers for many years into the function of a car. In the future, we may no longer need the evaluation standard of "car skills" and replace it with "car machines" to empower drivers.

At the same time, Aouita 12 is equipped with urban lane cruise assistance as standard, which can automatically keep the distance between cars, adaptively adjust the speed of following cars, identify lane lines and obstacles, and give corresponding tips and alarms, realize intelligent start and stop of traffic lights at intersections, and support the left and right steering of traffic levers at intersections.

Only NPCs need to enlarge their strokes within the prescribed scope, and the real strong never complain about the environment.

Excellent genes also enable Aouita 12 to demonstrate the same efficient learning ability. Through big data modeling, car owners can participate in the co-creation of intelligent driving strategy, and the intelligent driving system learns 10,000+kilometers every day. BEV Fusion Perception+Road Topology Reasoning Network (RCR) can build a scene from the vehicle side, so that vehicles can further get rid of the dependence on high-precision maps. In the fourth quarter of 2023, Aouita will gradually start the intelligent driving navigation assistance function that does not rely on high-precision maps, and it will be available all over the country in 2023.

A high degree of automation will require a higher level of security. Through the grid network algorithm occupied by GOD and the fusion perception of multi-sensors such as laser radar, millimeter-wave radar and camera, GAEB can help vehicles identify abnormal obstacles outside the "white list", such as mounds, lying pedestrians, rollover vehicles, falling cartons, falling rocks, fallen trees, etc., and take emergency braking in time before the collision risk of vehicles occurs, so as to avoid accidents or reduce accident losses. Million-level 3D point clouds truly restore the road conditions at night, easily deal with high beams, children, "ghost probes" and other scenes, without fear of dark environment, avoid road hidden dangers, and make driving at night safer.

At the same time, Aouita 12 comes standard with 19 active safety functions, including adaptive cruise assist (ACC), front-rear collision warning (FCW/RCW), front-rear transverse collision braking (FCTB/RCTB), door opening warning (DOW), blind ELKA monitoring warning (BSD), low-speed automatic emergency braking (LAEB), automatic emergency braking of special obstacles (GAEB) and emergency lane keeping assistance.

But Aouita is not a nerd who doesn’t understand interest like Sheldon. More often in life, what is needed to get along with people is intimate emotional intelligence:

The HarmonyOS cockpit based on HarmonyOS 4 makes Aouita 12 a full-scene intelligent interactive ceiling, and a large number of applications in the entire HarmonyOS ecological application market are open. Music applications include QQ music, Netease cloud music, cool dog music, Himalayan, national karaoke, singing bar, and video applications include Tencent video, Youku, Beep Beep, Mango TV, Infinitely close to the entertainment supply of smart phones, it also supports the cross-service flow of business data between mobile phones and car terminals. When logging in to Huawei account, you can also control related devices in your home in real time through car terminals, such as sweeping robots, intelligent air conditioners, air purifiers, lights, humidifiers, sockets, switches, etc., to achieve real ecological interconnection.

The multi-window function of one screen meets the interactive needs in different scenes, and there are exquisite and interesting HarmonyOS effects for driving mode, icon micro-effect, 3D simulation, system and other interfaces, which visually meets the needs of users for scientific aesthetics.

It is no exaggeration to say that Aouita 12′ s intelligent voice has reached the knee-jerk response level. It supports the sound source localization of the front and rear four divisions, accurately accepts voice commands, can continuously talk for up to 60s, supports multi-command quick response and continuous listening, and also includes intelligent AI feedback capabilities such as dialect recognition, fuzzy recognition and voiceprint duplication.

But simply falling in love with a sexy brain really exists?

There are many controversies about "intellectual love". For example, some people think that people who like Juan Fu and the hostess are not intellectual love, because they are all very good-looking. Are you sure you don’t like them because of their looks?

Of course, a sexy brain is the best medical beauty, but it does not prevent the audience from adding another filter to Juan Fu’s IQ.

Aouita 12, based on the Future Elegance design concept of future aesthetics, creates an elegant all-angle extreme coupe shape with an extreme proportion, and the front face of the disc wing created by Aouita family design language creates a fully quiet and luxurious hatchback without rear porthole, which achieves a unique appearance recognition with a high degree of design foresight and excellent streamline sense, and creates a futuristic atmosphere full of sci-fi.

The unique HALO interactive screen of the first quarter moon covers eight kinds of scene modes inside and outside the car, including pet mode, charging mode, pedestrian courtesy mode, temporary stop and pick-up mode, welcoming guests, sentry mode, holiday eggs and Autohold mode. It has the ability of continuous OTA iteration, and will push customized modes later. Aouita 12 is creating a colorful romantic atmosphere with light and shadow.

The external environment is minimalist and futuristic, while the indoor details are luxurious. Nappa ingenuity leather covers the seat and steering wheel; Super soft suede exquisite ceiling, providing a multi-level quality atmosphere. It has the first mass-produced real wood mobile phone panel among domestic automobile brands, which is made of real wood imported from Europe, including mother-of-pearl, ash and birch. The number of physical buttons is reduced, and only the essential buttons with high practicality are reserved. It brings clean visual comfort and greatly saves the space inside the car. At the same time, with the blessing of flexible stealth technology, the 35.4-inch 4K integrated remote screen can be integrated with the interior, achieving seamless interaction from the technical dimension, and combining advanced technology and technology to the ultimate balance.

In terms of color vision, Aouita 12, the exterior body, provides eight kinds of natural inspired appearance colors, including six high-gloss car colors of mountain blue, cloud purple, fog green, white, bright gray and obsidian black, and two matte car colors of sunrise purple and ink gray. The matte car paint process has the characteristics of high quality, high difficulty and high cost, and 1mm impurity particles can be reworked. Under more stringent process requirements, the one-time pass rate of high-gloss car paint is 95%. In terms of interior color matching, Aouita also provides three matching natural inspiration interior color matching, namely, jet black, contrast color series-twilight/smoky white and sports series-stone blue.

The advanced coupe image and the cabin experience with five senses created by the design concept of Futurn Elegance, the future aesthetics, show that Aouita 12 not only has a far-ahead super-high IQ, but also has a thoughtful and outstanding appearance, which makes people not only greedy their brains, but also their bodies.

Space must be invincible. Seating space: the seating space is large, quite comfortable and there is nothing wrong with it. There is a lot of space in front, and there is nothing wrong with crossing your legs in the middle space. The seats in the back are ok! When the whole family goes out: when going out, the carriage is too big, the air conditioner is turned on, and the temperature of the whole car is slow. It would be perfect to add two more air outlets in the back row. Luggage: It doesn’t matter how much luggage I put. I usually pull goods. The third row of seats are put down, and the trunk is basically abandoned, but there is still room for luggage at the middle side sliding door! Storage space: the storage space is ok. The front door can’t even hold a bottle of mineral water. It is estimated that the umbrella is designed, and the water cup can only be placed on the middle armrest!

Sometimes, it is more important to take every step right than to take every step well!

From the first chess piece in 2003 to the overall situation in 2021, BYD has completed the phased strategic goal, which is like the first stage of the Marvel universe that has ended. Word of mouth and box office have achieved a win-win situation. Today, let’s talk about BYD’s "DM hybrid system" (Dual Mode is dual-mode technology and BYD plug-in hybrid technology platform).

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.

Vehicles equipped with BYD DM-i hybrid system

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.
