Just as Wei Jianjun, Chairman of Great Wall Motor, wrote in "Can Great Wall Motor survive next year? Said:
"If we think we have succeeded, every successful past may be tripped over by the future; If we still can't see subversive changes, it must be us who are subverted; If we dare not break the rules, then the rules will soon become a cage of creation. "
Great Wall Motor has always been committed to the continuous innovation of core technologies. From the release of lemon, tank and coffee smart brands to the off-line of the new generation powertrain, Great Wall Motor has been constantly breaking through and upgrading.
12 On June 5438+05, Great Wall Motor officially made its world premiere in Baoding Haval Technology Center? The "lemon hybrid DHT" technology for full speed domain and full scene refers to two major fields in Japan with great influence in the hybrid field, which broke the technology monopoly of joint ventures on behalf of independent brands.
"lemon mixed DHT" is called "dedicated? Half-breed? Technology's "special technology for hybrid power" adopts the series-parallel hybrid power technology of two motors, one generating one driving and two shifting gears. Covers almost all travel scenarios such as low-speed travel, long-term parking, high-speed/urban loop. On urban roads, it can bring users a travel life with lower fuel consumption, stronger power and more comfortable experience.
FYI: Toyota twin engines: no direct drive capability. Honda immd: high-speed first-gear direct drive. Great wall DHT: two-speed direct drive.
From a technical point of view, the technical foresight and advancement of lemon hybrid DHT are embodied in "1-2-3" (one hybrid system, two power structures and three powertrains).
Feng Mu, vice president of commodity strategy and technology research and development of Great Wall Motor, explained the technical strategy of "lemon mixed DHT"
Hybrid power system means that "Lemon Hybrid Power DHT" adopts a two-motor series-parallel topological structure, and has various working modes such as pure electricity, series connection and energy recovery. Through the intelligent switching of the control system, the perfect balance between high performance and high performance is achieved in the full speed domain and the whole scene.
The two power architectures refer to HEV/PHEV, which are derived from the series-parallel topology of two motors to meet different consumption requirements.
HEV architecture, compared with Toyota, Great Wall HEV not only pays attention to fuel economy, but also emphasizes power performance. The emphasis is on the ultra-low fuel consumption of urban road conditions and the instantaneous acceleration ability of medium and high-speed road conditions. The comprehensive efficiency of power system can reach more than 50%, and the comprehensive fuel consumption of A-class SUV powered by HEV is as low as 4.6L/ 100km.
In the actual test, taking the B-class SUV with HEV architecture as an example, compared with fuel products, the fuel saving rate can reach 35-50%, and the acceleration time of 0- 100km/h is greatly shortened by 1.5s, which is only 7.5s..
Schematic diagram of main components and operation mode of "lemon hybrid DHT"
PHEV architecture, equipped with 45 kWh high-capacity and high-efficiency hybrid battery, is really big. Unlike other plug-in hybrid vehicles, the battery is placed under the floor like an electric car. The most direct benefit is simple and rude: the pure electric cruising range of its PHEV model is 200km!
What is this concept?
Let's not talk about the current situation that the battery life of PHEV models in the existing market can only linger at 50km. Even if it is a pure electric vehicle, there are still models with EV battery life below 200km!
Great Wall Motor's PHEV Bull X really surprised me!
Three powertrains refer to two special Atkinson cycle modes in HEV/PHEV, one is 1.5 self-priming and the other is1.5t. According to different engines, three kinds of hybrid power systems are formed, and the total power of the system ranges from 140kW to 320kW, which can be A.
The first type: 1.5L hybrid engine +DHT 100( 100kW highly integrated hybrid gearbox), which can realize HEV/PHEV power and is mainly used for A-class vehicles;
The second type: 1.5T hybrid engine +DHT 130( 130kW highly integrated hybrid gearbox), which can realize HEV/PHEV two kinds of power, mainly used for B-class vehicles;
The third type: 1.5T hybrid engine +DHT 130+P4( 135kW three-in-one two-speed electric drive rear axle), which can realize PHEV power and is mainly used for C-class vehicles;
Based on this, "lemon hybrid DHT" can serve users with different needs in different regions of the world and has a high degree of flexibility.
Over the past 30 years, Great Wall Motor has grown from a small local factory to a leading domestic automobile enterprise with annual sales of one million for four consecutive years. It dares to think and fight, is good at finding light from adversity, and is better at finding shadows from prosperity.
In the era of global economic downturn, dividends will be exhausted, and foreign brands and new car-making forces will kill each other, Great Wall Motor will take precautions. As early as two or three years ago, it has laid out this hybrid technology, which is highly consistent with the "increasing hybrid investment and expanding hybrid market" emphasized in the recently released roadmap of energy-saving and new energy vehicle technology 2.0.
The whole set of technology is completely independently designed and developed by Great Wall Motor, with completely independent intellectual property rights, with a total of 199 patents, including 80 core patents.
Having a global supply chain and independent control of key components can not only ensure that consumers can enjoy the technical division of labor and cost-effective bonus brought by the global division of labor, but also avoid getting stuck in key technologies and ensure the iterative update and sustainable development of technology research and development.
Its release completely broke the long-term monopoly pattern of joint venture brands in the field of hybrid technology, and set a new trend of hybrid technology in China, and renamed it "Great Wall of Science and Technology" and "Created by China".
Shan Hongyan, vice president of Great Wall Motor R&D, and four industry experts discuss the present and future of hybrid technology.
This also means that Great Wall Motor has once again ushered in a historic breakthrough in core technology, further consolidating the technical foundation of Great Wall Motor's global development and becoming an important support in the globalization strategy.
After 30 years of hard work, Great Wall Motor has always insisted on leading the brand with technology and driving development with innovation. Today, with the changes in the automobile industry in full swing, "lemon hybrid DHT" embodies the comprehensive consideration of Great Wall Motor on the coordinated development of energy, environment, people and vehicles, and shows that Great Wall Motor is at the forefront of the global hybrid technology research and development wave.
Everything is ready. According to relevant personnel, the hybrid car equipped with "lemon hybrid DHT" will be listed next year. At present, Haval H6 has a hybrid Hev version for road testing. Interested riders may wish to have a look with me. I believe the Great Wall won't let you down.
