Great Wall Motors has made new moves on the road to technological empowerment for brand improvement.
On December 15, Great Wall Motors officially launched the "Lemon Hybrid DHT" technology at the Haval Technical Center in Baoding, becoming the latest development after Great Wall Motors' new high-end electric vehicle brand (SL project) surfaced this month. Another signal released by the new energy market.
At the press conference, Mu Feng, Vice President of Product Strategy and Technology R&D of Great Wall Motors, introduced that for the "Lemon Hybrid DHT" that focuses on urban travel and takes into account the needs of high-speed travel scenarios, it can be summarized as "1- 2-3", that is, a hybrid system, two power architectures, and three sets of powertrains.
From a consumer's perspective, this system has a minimum fuel consumption of 4.6L per 100 kilometers in both HEV and PHEV power modes, a PHEV pure electric range of 200km, and the fastest 100-mph time in 5.2 seconds. Technical Highlights.
As for the brand, in addition to refreshing the technical image of Great Wall Motors, the lemon hybrid DHT system will have Japanese hybrid "pacesetters" such as Toyota and Honda in the front, and independent camps such as Geely and Changan in the future. The hybrid market continues to be on the offensive. Great Wall Motors, which is "testing the waters" for the second time after the WEY P8, seems to be ready for change.
Judging from the lemon hybrid DHT technology released this time, Great Wall Motors has solved at least two problems, namely user rigid needs and technological innovation.
Taking users’ immediate needs as an example, the most significant difference between hybrid vehicles and fuel vehicles is fuel consumption. However, in the face of pragmatism at this stage, low fuel consumption is no longer the traditional single consumer demand of users. Performance considerations have gradually become an advanced requirement for hybrid users.
Therefore, for Great Wall Motors’ lemon hybrid DHT technology, its biggest feature is the technical balance between efficiency and performance, and the official “1-2-3” password is exactly It is a concentrated summary of the technical features of lemon hybrid DHT.
To put it simply, Lemon Hybrid DHT is a highly integrated gasoline-electric hybrid DHT system. The password "1" refers to the dual-motor hybrid topology used by Lemon Hybrid DHT. The working modes include pure electric, hybrid, series, energy recovery, etc.
The password “2” refers to the two power architectures of HEV and PHEV; the password “3” refers to the HEV hybrid architecture (1.5L?+DHT100) and PHEV hybrid architecture (1.5T?+ DHT130), and PHEV four-wheel drive hybrid architecture (1.5T+DHT13P4) three powertrains.
Specifically, under the HEV hybrid architecture solution focusing on energy efficiency, the total power of the system is 180kW, of which the A-class SUV equipped with the system has a minimum fuel consumption of 4.6L per 100 kilometers; in the PHEV that focuses more on performance solutions In the architecture mode, the total power of the two-wheel drive system is 240kW, and the total power of the four-wheel drive system is 320kW. The B-class and C-class SUVs built based on this solution can accelerate to 100 kilometers in 7.2 seconds and 5.2 seconds respectively. In addition, the 45kWh large-capacity battery It also brings a pure electric range of up to 200km.
It can be said that from technical highlights to power features, various advantages presented in numbers point to the rigid needs of users. But what is the difference between the lemon hybrid DHT technology, which is entering the hybrid market for the second time, and the hybrid technology logic of Toyota THS-II and Honda i-MMD?
From the perspective of technological innovation, first of all, this petrol-electric hybrid DHT system is a hybrid technology system constructed with a "seven-in-one" high-efficiency multi-mode hybrid assembly. It is composed of 1.5L and 1.5T hybrid special engines, dual power generation/drive motors, fixed-axis gearbox, dual motor controllers, and integrated DCDC.
In addition, judging from the existing hybrid strategies in the domestic hybrid market, there are currently power split (motor speed regulation, speed coupling), single-speed hybrid (rigid coupling), series range extension and oil Electric transfer, etc.
Among them, Toyota THS-II and Honda i-MMD, two Japanese hybrid strategies, can be classified as power-split heavy hybrid systems, and their characteristics are more focused on the economic performance of the system. , but the strategic power of this technical route and single-speed hybrid will be slightly insufficient compared to the economic performance, and the power performance of the series extended range will directly depend on the power of the motor.
In other words, the consideration of the balance between energy efficiency and performance is not only the technical highlight expected by consumers, but also the main technical focus of Lemon Hybrid DHT.
It is worth mentioning that since the current mass-produced models equipped with lemon hybrid DHT have not yet been officially determined, Yi Ge, after a simple test drive experience and trial installation of the car, started from the EV mode intelligently selected according to the system load, Features such as series mode, engine power gear direct drive mode and engine economy gear direct drive mode found that the lemon hybrid DHT using two-speed hybrid is more similar to Honda SPORT?HYBRID?e+ hybrid logic from the perspective of hybrid strategy , so the detailed test drive interpretation of the two related products will wait until the production vehicle equipped with lemon hybrid DHT is officially released.
The release of Great Wall Motors Lemon Hybrid DHT has once again made the promising prospects of the hybrid vehicle market clear. From the Japanese brands that laid out hybrid routes earlier in the country, to the independent car companies that are now vying to be the first to launch efforts, the hybrid offensive is particularly prominent at the turning point of the electrification transformation of the auto market. With the help of lemon hybrid DHT, Brother Yi believes that Great Wall Motors has released three major signals.
First, it is a policy-oriented signal. According to Dong Yang, Vice Chairman of the China Electric Vehicles Association of 100, it is urgent for independent brands to take off in the field of hybrid vehicles. This is not only because joint venture brands have earlier strategies and increasingly complete technical reserves on the hybrid technology route, but also because domestic new brands Changes in the energy market structure have also made hybrid technology one of the most important development routes currently and even in the future.
According to the analysis of "Energy Saving and New Energy Vehicle Technology Roadmap 2.0", "It is expected that by 2035, all traditional energy-powered passenger vehicles will be converted into hybrid models, and hybrid models and new energy vehicles will (Pure electric vehicles, plug-in hybrid vehicles, and fuel cell vehicles) each account for 50% of the annual sales, thereby realizing the comprehensive electrification transformation of the automobile industry. ”
Therefore, the future development of the domestic new energy vehicle market will be achieved. Following the trend, the lemon hybrid DHT technology released by Great Wall Motors can be said to be "just in time" in terms of time. The implementation of more and more hybrid technologies not only emphasizes the future trend of the domestic new energy vehicle market, but also accelerates the pace of change of car companies on the new energy technology route.
Second, it is a signal for the Great Wall to take the lead in strategic layout. Through the lemon hybrid DHT technology of "one hybrid system, two power architectures, and three sets of powertrains", Great Wall Motors once again completed the acceleration on the new energy track and further implemented the market segment strategy. With the corresponding release of three sets of powertrains and three models, Great Wall Motors will lock in the future market position of related products "in advance", thereby improving the layout of new energy technology routes and strengthening the overall brand strength and product competitiveness.
Third, it is a signal that Great Wall continues to launch a technological offensive. 2020 is the year when Great Wall Motors, which is "standing at thirty", launches its own "soul torture", from "lemon platform" and "coffee intelligence" to "big dog", "good cat" and "tank". to new smart electrified high-end brands, etc., all of which demonstrate Great Wall Motors' actions and determination to launch a reform offensive from the front and side.
Therefore, the arrival of Lemon Hybrid DHT is undoubtedly one of the boosters to "awaken" the brand as a whole. No matter from the perspective of technological innovation or multi-product layout, Lemon Hybrid DHT technology will It is a "launching board" for accelerating Great Wall Motor's blueprint for the new energy market, and it is also an important booster for its technical image.
Written at the end
The domestic hybrid vehicle war situation will continue to evolve in the future. However, judging from the results of a series of changes in the brand this year, the hot sales of the tank and Big Dog series, as well as the continuous innovation in marketing and other aspects, it seems that these have laid the foundation for Great Wall Motors to rush to the next battle.
