On January 17, the Association released an in-depth analysis report on the national passenger car market in December 2021, summarizing 2021 through data. Under the influence of the "new crown" epidemic, the overall retail sales of the narrow passenger car market in the mainland reached about 20.146 million units last year, a slight increase of 4.4% compared with 2020, which is an extremely difficult year .
The reason for this is that if you look at the single-month sales trend, the narrow passenger car market in June has already declined, and retail sales have begun to show negative year-on-year growth. In addition to the good foundation laid in the first five months, the "hot" of the new energy passenger car market has played a more critical role, according to the statistics of the Association of Passenger Vehicles, the retail sales of the market in 2021 exceeded 2.988 million units, an increase of about 169.1% year-on-year. Among them, the fastest growth rate is not a pure electric model, but a plug-in hybrid model, with more than 544,000 new vehicles sold in 2021, an increase of 171.2% year-on-year, and the momentum is the most "vigorous".
■ A technological leap worthy of excitement
Looking back at the past year, many Chinese brands have inserted and mixed technologies, such as BYD's DM-i system, Chery Kunpeng DHT system, Great Wall Lemon DHT system and Geely Lei's Shenzhi Qing Hi· X hybrid system has landed, although the technical path of these technologies is not the same, but in the pure electric endurance, comprehensive fuel consumption and power performance have a qualitative leap, the application of these technologies of the model is also in the market by the majority of consumers attention, which is more exciting and exciting than the sales volume "by leaps and bounds".
For plug-in hybrid technology, the pain point is how to more intelligently and efficiently distribute the power generated by the combustion engine and the electric motor, so that a better "hybrid effect" between them can be formed, and it can continue to provide strong performance in more complex driving environments, while energy consumption can be kept low.
In many plug-in and mixing systems in the past, the traditional engine power system (internal combustion engine + clutch) is usually connected to the motor system (motor + electronic control), and then the power mode of pure electricity, pure oil, oil-electric hybrid is generated, and then the logic of power is continuously optimized to achieve efficient operation and reduce power loss. Like BYD's DM-i system is one of the best, through the excellent mechanical structure technology and intelligent software blessing, so that the model equipped with this technology in most scenarios are sensitive and efficient pure electric power drive, only in individual environments will use oil-electric hybrid or pure oil drive, both to ensure sufficient power and reduce fuel consumption.
Now, with the development of technology, we are seeing some brands to achieve more intelligent and accurate power distribution by adding hybrid-specific multi-speed transmissions (DHTs) to the two powertrains. Like Chery's Kunpeng DHT system, Geely's Thunder God Intelligence Qi· The X hybrid system and the Great Wall lemon DHT system are representatives of this type of plug-in hybrid technology. They are equipped with three-speed and two-speed DHT transmissions, which not only have super acceleration performance and extremely low comprehensive fuel consumption, but also can cope with more driving environments by switching more driving modes.
For example, chery's Kunpeng DHT super hybrid system, which highly integrates the motor controller, dual motors, and transmission, and relies on the 3 physical gears of the DHT transmission to have a wide working range, which allows vehicles to switch power output modes more intelligently and smoothly in the face of starting, medium and low speed, elevated, overtaking, red light, congestion, high speed, long distance, mountain road, high speed steering, ice/mud/sand and other driving scenarios.
Speaking of output mode, most of the current hybrid technology is still only the engine direct drive, motor direct drive, series increase range, parallel increase range four conventional modes, at most there is an energy recovery mode. However, Chery has very "boldly" set up 9 drive modes in the Kunpeng DHT hybrid system, such as single motor direct drive, dual motor direct drive, series extended range, engine direct drive, parallel drive, park charging, driving charging, single motor brake energy recovery, and dual motor brake recovery, to cope with the complex road traffic situation mentioned above.
In addition to the DHT transmission, the power configuration in the Kunpeng DHT hybrid system is also key. In a conventional plug-in hybrid system, there is usually an internal combustion engine and 1 to 2 electric motors to form a drive system, and then a separate generator will be configured to provide power, such a design is not only complex in structure, occupies space, and "special purpose" is not flexible enough, the cost is still very high. The Kunpeng DHT hybrid system has 1 internal combustion engine and 2 motors, but the motor can undertake power generation and drive work at the same time, so it can have three independent power sources at the same time, and the DHT transmission can flexibly generate 11 working gears, which not only allows the power to continue to maintain "high energy and low consumption", but also streamlines and optimizes the structure, so that the space required for this power system is also smaller, and the production cost is lower.
Having said all the technical and structural characteristics, what kind of performance does this hybrid system have after landing? At present, the Tiggo 8 PLUS Kunpeng e+ is the two-wheel drive version of the Kunpeng DHT hybrid system, which has a comprehensive maximum power of 240kW, a maximum torque of 565N·m, only 7s acceleration per 100 kilometers, a pure electric endurance of 100km, a comprehensive fuel consumption of 100 kilometers of 1L, and a fuel consumption of 5.0L. Compared to other plug-in hybrid systems, these performance figures are not inferior and are at the top level.
In addition, the system will also introduce a four-wheel drive version with the addition of a rear axle motor, and the four power sources will be output at the same time, allowing the vehicle to speed up from stationary to 100km/h in less than 5 seconds.
■ Product landing worth looking forward to
Of course, after having leading technology, it is also necessary to land high-quality model products in order to truly transform the "first opportunity" into a "weapon" to seize the market. At present, Great Wall's sub-brands Weipai, Geely and Chery have successively released the first models equipped with DHT hybrid system. Among them, the Tiggo 8 PLUS Kunpeng e+ from Chery is particularly noteworthy, not long ago the official announcement of the price of the new car, a total of two versions are available, after the subsidy first enjoyed the price of 151,800 and 165,800 yuan respectively.
In addition to the power system, the new car is also excellent in terms of technology, intelligence and health, such as the model can be set up through the car machine system and mobile phone APP to book charging. In addition, before each drive out, we can pre-activate the battery heating and air conditioning, so that the vehicle can fully "warm up" and make the interior more comfortable.
In the face of the current headache for consumers - when the vehicle battery is delinquent, the high-voltage system can be awakened through the HCU, and the battery can be recharged through the power battery to ensure that the vehicle can be started smoothly at any time, while effectively avoiding long-term deep power loss and prolonging the battery life. In addition, the car is equipped with Bosch's latest IPB intelligent electronic control dynamic system, engineers use this system to adjust the braking distance, braking comfort, energy recovery efficiency to the best state, so that the car has good handling and comfort.
In addition, the Tiggo 8 PLUS Kunpeng e+ car spares no effort in intelligent configuration and cockpit design. The new car is equipped with a newly upgraded "Xiaoqi Intelligent Car Butler 3.0" system, with deep learning, cloud live entertainment interconnection, enhanced Natural Language interaction capabilities, and the whole series is equipped with a Beidou + GPS dual-mode navigation system with a stronger signal and higher accuracy, and the car also integrates audio and video entertainment applications such as Vibrato/Volcano Video, as well as hybrid special software that can monitor the power status in real time. In terms of user health, the "C-PURE Chery Net Cube Green Cockpit" equipped with Tiggo 8 PLUS Kunpeng e+ adopts The European standard environmental protection technology, ecological design concept and pure respiratory system to achieve the odor of the new car 3.0 level, effectively ensuring the health and comfort of the cockpit.
■ Bang reviews
In fact, the state has long had a strategic layout for plug-in hybrid technology, and in 2016, the Ministry of Science and Technology has launched the key special implementation plan for new energy vehicles in the national key research and development plan, and began to establish a sound electric vehicle power system technology system and industrial chain. Chery Automobile also responded positively, and in 2018, it led the implementation of two national key research and development projects of "new cost-effective passenger car hybrid assembly development and vehicle integration" and "hybrid engine development", and the Kunpeng DHT super hybrid system is the result of three years.
With the maturity of plug-in hybrid technology, the oilable, electric, efficient and anxiety-free car experience will increase consumer trust in such models, and we judge that in the near future, they will replace the "must-choose" status of conventional fuel vehicles in people's minds. This also allows more and more brands to see the opportunity to seize more market share through plug-and-mix models, rather than just competing with other electrified models for the already small number of new energy market "cakes".
Therefore, we expect that the technology and models represented by Kunpeng DHT Super Hybrid Technology and Tiggo 8 PLUS Kunpeng e+ can help Chinese brands such as Chery take the lead in seizing the "highland" of technology and market, while allowing consumers to have more affordable and rich car purchase options, and can help the country achieve the important strategic tasks of "carbon neutrality" and "carbon peaking" as soon as possible.
