China's new energy automobile industry has experienced eight years of rapid growth and has entered the second half of the competition.
With the closing of the window period, unprepared enterprises lost their tickets to participate in future competition. The protagonists in the second half will be those brands with strong technical reserves and ready industrial layout.
Qiu Xiandong, Director, General Manager and Deputy Secretary of the Party Committee of China FAW Group Corporation
On April 8th, Hongqi held the "Huiqi Technology-Hongqi New Energy Technology Conference" in Changchun. In the introduction of Qiu Xiandong, director, general manager and deputy secretary of the Party Committee of China FAW Group, HMP(HQ Modular Power), the third platform under the "Flag" super architecture, was officially unveiled.
Qiu Xiandong said: "China FAW and Hongqi brand will go all out to' all in' new energy, persist in shaping with' technology', cast souls with' technology' and seize the PHEV track."
According to the plan, two vehicles equipped with HMP platform will be put into mass production in Hongqi in the second half of this year. In the future, Hongqi will gradually introduce a variety of hybrid models to the market on the new platform.
Technical red flag, mixed feelings "show muscles"
In the past quarter, China's new energy vehicles increased by 25% year-on-year, and it is estimated that the new energy penetration rate will exceed 30% in the whole year. Among them, the increase of plug-in hybrid power is obviously higher than that of pure power, and it has become the most powerful new energy technology route at present.
This is not only the direction of the market, but also the choice of national new energy strategy. Gao, an academician of the Chinese Academy of Sciences and vice chairman of China Electric Vehicle committee of 100, believes that China has a vast territory and a complex environment for the use of automobiles, so it is impossible for one energy source to dominate. In the future, China automobile will inevitably move towards the road of multi-energy development.
Plug-in hybrid technology combines the advantages of fuel vehicles and pure electric vehicles, but the complexity of system integration also restricts the early development of plug-in hybrid. With the continuous breakthrough of plug-in hybrid technology, the current plug-in hybrid models have formed a subversive advantage.
The plug-in hybrid platform released this time is the latest achievement of FAW Hongqi in the field of new energy.
At the 5438+10.8 June this year, Hongqi released the "Flag" High-end Electric Intelligent Super Architecture (FMEs), which is a super architecture that integrates the eight technical fields of FAW Group and the key technical fields of 1 15, with all major breakthroughs, and has nearly/kloc-0.
The "Flag" super architecture consists of an electrified and intelligent integration platform HME and an intelligent and experiential integration platform HIS. This time, the newly released Red Flag hybrid platform HMP has become the third largest platform under the super architecture.
As the first hybrid platform of Hongqi, HMP has been built for five years, breaking through 526 key core technologies, many of which are world-class. The plug-in hybrid vehicle developed from this will have strong market competitiveness.
Hongqi HMP platform is composed of four core systems: hybrid transmission, hybrid engine, intelligent electric drive and safety battery, and intelligent energy control model, which fully constructs the technological leading edge of Hongqi plug-in hybrid vehicle.
Qiu Xiandong said: "Under the guidance of the new strategy, FAW Hongqi will continue its pursuit of safety, comfort and excellent quality, continue to innovate, create products with better performance and more extreme experience, and work with users to control their dreams and create a better future."
Through this "muscle show", Hongqi told the outside world what she had been "busy" with in recent years and what achievements she had made. More importantly, in the complicated technological changes, the "national team" not only has sober insight, but also has lasting and vigorous innovation energy.
Four cores and one module
Solve the pain points of mixed applications
Compared with product design, this red flag focuses more on what kind of experience upgrade technological innovation can bring to users. Focusing on the characteristics of safety, low carbon, pleasure and strong platform, Hongqi hybrid technology solves the application pain of plug-in hybrid technology through four core systems and a set of intelligent energy control models, which is a comprehensive upgrade of plug-in hybrid technology.
Safety is the foundation of Hongqi brand-HMP platform builds multiple safety barriers to completely eliminate the risk of battery thermal diffusion.
Low-carbon is the direction of Hongqi Technology-supporting pure endurance of more than 200km and "zero" fuel consumption in daily traffic; The fuel consumption of the B-class car is less than 4 liters per 100 kilometers, and the cruising range exceeds 1400km, making it easy to travel long distances.
Pleasure is the promise of Hongqi products-relying on comprehensive vibration isolation and noise reduction design and intelligent control strategy, providing a quiet and stable driving environment, supporting various high-end equipment such as steer-by-wire and active suspension to meet the needs of the whole scene.
Strong, is the characteristic of the red flag model-both horizontal and vertical models, covering all models of red flag A to C+; All models support four-wheel drive with a maximum power of 495kW.
Quad-core HMP high efficiency hybrid power transmission system;
Adhering to the concept of "luxury quality, integrated innovation and extreme exquisiteness" and relying on original configuration, high integration and extreme lean design, Hongqi has built an efficient, powerful and silent hybrid transmission. The comprehensive efficiency is above 90%, the output torque of longitudinal transmission is above 4500n·m, the output torque of transverse transmission is above 3900n·m, and the global order noise is below 65 dB.
LDU45 is the world's first vertical front-drive dual-motor multi-speed hybrid transmission, which is applied to hybrid vehicles above Class C. It integrates drive axle, transmission, motor and controller, and solves the technical difficulties of traditional vertical transmission in transmitting power forward, achieving the shortest transmission path and the lowest system loss. The multi-gear design keeps the engine speed below 2000 rpm during high-speed cruising, which is in a high-efficiency and low-noise area, effectively solving the problems of high-speed noise and high fuel consumption of most hybrid electric vehicles at present.
In addition, Hongqi has also developed a very compact and efficient transverse hybrid transmission HDU35, which is applied to A-class and B-class hybrid vehicles with the shortest axial length of 376mm in the industry. Medium voltage silicon carbide inverter and multi-layer flat wire oil-cooled motor are used for the first time, which reduces the assembly weight by more than 10kg compared with similar products. At the same time, the newly developed dual-pump hydraulic system has reached the ultimate efficiency of HDU35 products, and the power consumption of the system is reduced by 80% compared with similar products.
Quad-core HMP high performance hybrid engine system;
Pursuing high efficiency, comfort and intelligence, Hongqi has built two hybrid engines, 20TD and 15TD, with the thermal efficiency reaching the highest in the industry of 44.3% and 45.2% respectively. The hybrid engine has solved the international problems of "cleaner" and "stronger" at the same time. Under the premise of ensuring high thermal efficiency, it can still achieve ultra-high power above 60kW/L, which is at the international leading level.
The 20TD hybrid engine adopts many technologies, such as high compression ratio Miller cycle and distributed exhaust gas recirculation, and is equipped with a two-axis balance system, which makes the operation more stable. Aiming at the frequent start-stop working scene, piston self-positioning technology is adopted to reduce vibration and noise 12%, reaching the best level in the same level in the world.
15TD hybrid engine adopts two industry-first technologies of integrated intake and separated exhaust pressurization, which can reduce intake resistance and exhaust interference and make the engine breathe more smoothly. At the same time, it is equipped with a newly developed dynamic lubrication control technology, which reduces the friction loss by 28% and further saves energy consumption.
Moreover, Hongqi has reserved the next generation lean-burn engine, and the measured thermal efficiency has exceeded 47%. In the future, it will become an important force to further push the hybrid engine to break through the thermal efficiency barrier at full speed.
Quad-core HMP power decoupling electric drive system;
Let the driving control follow your heart and let the power surge. Hongqi launches power decoupling electric drive system. With the innovative structure of intelligent disconnection and electric auxiliary drive, the four-wheel drive and two-wheel drive modes can be automatically switched within 100ms, so that there is no resistance loss when the vehicle runs economically, and the energy consumption of four-wheel drive reaches the level of two-wheel drive, which overcomes the industrial difficulty of high no-load energy consumption of new energy four-wheel drive electric drive at present.
Hongqi power decoupling electric drive system can output more than 200kW, and the speed reaches 18000 rpm. The latest generation of high-performance customized magnetic steel and multi-layer square conductor technology are adopted to realize extreme miniaturization and light weight, and the material consumption is reduced by 17% and the weight is less than 74kg；; The breakthrough of global deep frequency conversion and super overmodulation technology makes the vehicle provide better dynamic response and acceleration performance when driving at high speed.
Moreover, the power decoupling electric drive also has excellent mute performance, and the global order noise of silent packaging is less than 65 dB, which is the benchmark level of the international electric drive industry.
HMP four-core high-safety low-temperature resistant battery system;
Around the full-scene safety and all-weather enjoyment of the battery system, Hongqi has achieved double safety protection and improved low-temperature performance. Resistant to external damage, the lightweight all-composite box has the strength as high as 1000 MPa and the material characteristics of non-embrittlement, which gives the battery armor-like structural protection when the weight is reduced by more than 15% compared with the metal box; High temperature resistance 1000℃, full insulation, forming three-dimensional electric heating protection, completely eliminating risks such as short circuit and arc.
In order to effectively avoid internal anomalies, high-stability battery materials and cell structure safety technology are adopted to improve the safety of the cell body; Real-time monitoring and active maintenance of battery health through cloud housekeeper big data drive technology. With the high-safety battery technology, the whole life cycle safety control is implemented to protect users' safety anytime and anywhere!
At the same time, Hongqi has also developed a low-temperature active battery and developed a multi-source intelligent heating technology. Combined with the low thermal conductivity of the fully composite box, it effectively solved the user's pain point of battery performance degradation in the low-temperature environment of electric vehicles. According to the actual measurement on the bench, the available energy is 8% higher than that of the metal box battery when it is placed at minus 20℃ 12 hour, and the power output capacity is more than 25% higher than that of the metal box battery. Really let users travel freely without fear of low temperature.
HMP exclusive intelligent energy control model;
On the basis of the four core systems, Hongqi is also committed to developing its own smart energy control model to accurately control and fully release the system potential, and provide users with the ultimate energy-saving and beautiful driving experience.
This algorithm means that by giving the red-flag car self-awareness, it can identify itself and adapt itself, ensuring the unity of thinking and synchronization of each system, and achieving the best effect with the least energy consumption; Let the red-flag car clearly understand the external environment, predict the action, and let each system meet the challenge in the best state at any time.
The core of the model is the global energy flow intelligent management algorithm and the intelligent perception energy-saving planning algorithm. The global energy flow intelligent management algorithm, which integrates the transient characteristics of each factor and the user's personalized usage habits, can instantly identify the state of each system and the driver's intention, make the best judgment and issue the best instructions, and meet the dual demands of users for economy and power experience; Intelligent energy-saving planning algorithm, based on cloud big data and road network information, applies machine learning and global optimization to realize the optimal dynamic adjustment of energy without wasting a trace of energy.
For example, when there is traffic jam in the city, the algorithm can automatically identify and enter the pure electric drive and series priority mode, and the motor efficiency is always at the best through torque adjustment. After entering the highway with smooth traffic, the algorithm can actively identify the driver's style, intelligently distribute the electric drive and engine output torque, accurately control the battery SOC level, and prepare for the next road in advance, completely breaking the inertia logic of using electricity and oil instead of electricity.
Through multi-sample measurement, the intelligent energy management algorithm of Hongqi can reduce the fuel consumption of skilled drivers by more than 8% on average, and realize the intelligent control of machine brain far beyond that of human brain.
In the urban life circle, HMP platform models can bring longer pure electric mileage, reduce vehicle costs with the characteristics of strong economy, fast energy replenishment and low energy replenishment frequency, thus saving energy and labor in commuting and truly realizing "zero" fuel consumption and no burden travel.
In long-distance driving scenarios such as cross-city, outing and self-driving trip, HMP platform models can be called "energy management experts", achieving lower fuel consumption and longer battery life with excellent energy distribution. But also gives consideration to the strong power output to meet the comprehensive needs under various road conditions.
Write at the end:
Different from the past, this red flag has brought an almost pure technology release. After the meeting, some participants said with emotion: "Although I don't know anything, I was greatly shocked."
In fact, this is a brand breakthrough that Hongqi needs now. From the red flag of domestic cars in the past, to the red flag of the market in the renaissance period, and then to the red flag of technology in the new energy era. In the technological fission period, Hongqi needs to respond to consumers' expectations with this solid and hard-core technical force supported by data, and once again become the leader of the new era.
In the era of new energy, it is also the era of younger cars, and the information gap between car companies and consumers is constantly being erased. For the cognition of a brand, consumers should not only look at its propaganda slogan, but also care about its technical details.
In the past, consumers generally believed that Red Flag was a brand with more feelings than technology. But in fact, the reason why Hongqi can become a national car has always relied on excellent technology and quality.
The release of the red flag hybrid platform is only a vertical transmission, which solves the problem of "difficult to carry" such as active suspension and large-capacity battery, and brings plug-in hybrid to the real luxury car field above class C.
This is a high degree of innovation! It is precisely because of a series of such high-level breakthrough innovations that we have the confidence to release the new energy strategy of Hongqi.
From the release of HMP hybrid platform to the launch of two hybrid models in the second half of the year, not only did the outside world see the hidden real strength of Hongqi in the new energy field, but also people were full of imagination and expectation for the future development of Hongqi.
