Nowadays, the darling of the new energy vehicle market is not just pure electric.
On June 5438+ 10 this year, the Technical Roadmap 2.0 for Energy Saving and New Energy Vehicles (hereinafter referred to as Technical Roadmap 2.0), which was guided by the Ministry of Industry and Information Technology and revised by China Automotive Engineering Society, was released in Shanghai. Technology roadmap 2.0 shows that by 2035, all domestic traditional energy vehicles will be converted into hybrid vehicles, with hybrid and new energy vehicles accounting for 50% respectively. In the future, China's new energy vehicles and energy-saving vehicles should develop simultaneously.
In this context, hybrid technology has also become another direction of the layout of car companies after pure electricity.
65438+February 65438+May, Great Wall Motor officially launched the full-speed domain and full-scene "lemon hybrid DHT" technology in Baoding Haval Technology Center. It is reported that "lemon hybrid DHT" is a set of highly integrated, efficient and multi-mode hybrid electric power system, and it is also the core technical route in the Great Wall hybrid technical route.
"lemon mixed DHT" was launched in the world
It is worth mentioning that at present, independent brands actively seeking layout in the field of hybrid power include BYD, GAC and Geely.
It can be seen that hybrid technology has become another commanding height of the automobile industry, especially independent brands.
What is the technology of "lemon mixed DHT"?
What is "lemon mixed DHT"?
"'Lemon Hybrid DHT' is a high-integration, high-efficiency and multi-mode hybrid electric system designed and developed by Great Wall Motor. It has completely independent intellectual property rights, with a total of 199 patents and 80 core patents." Great Wall Motor said.
It is understood that this technology also adopts the dual-motor series-parallel hybrid technology, which can achieve a perfect balance between high performance and high performance in full speed domain and full scene.
Song, Vice President of Great Wall Motor Technology, explains the technical characteristics of "lemon mixed DHT"
"'lemon mixed DHT' pays attention to the needs and experiences of consumers, and its biggest advantage is fast, economical, quiet and smooth." Song, vice president of Great Wall Motor Technology, said at the press conference.
In July this year, Great Wall Motor released three new scientific and technological brands, namely, global high-intelligence modular platform lemon, brand-new intelligent platform coffee and intelligent professional off-road platform tank, covering the whole industrial chain value innovation technology system of automobile R&D, design, production and automobile life. The "lemon mixed DHT" released this time is an important part of the "lemon" platform technology. Its application covers almost all travel scenarios such as low-speed driving on urban roads, long-time parking, high-speed/urban loop. It can bring users lower fuel consumption, stronger motivation and more comfortable travel life.
At the same time, Feng Mu, vice president of commodity strategy and technology research and development of Great Wall Motor, also said: "Its forward-looking and advanced nature is also reflected in'1-2-3', that is, a hybrid power system, two power architectures and three powertrains."

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.
Two power architectures, that is, facing different consumption demands, derive two power architectures, HEV/PHEV. HEV architecture focuses 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 compact SUV powered by HEV is as low as 4.6L/ 100 km. PHEV architecture has the highest performance in the industry, with a pure battery life of 200km and 80% in 30 minutes. In the actual test, the fuel saving rate of medium-sized SUV models under the framework of HEV can reach 35~50% compared with fuel models.
Three powertrains, namely 1.5L+DHT 100, 1.5T+DHT 130,1.5t+DHT130+under HEV/PHEV architecture.

Know China's hybrid technology best.
In contrast, it is not too early for independent brands to develop hybrid technology.
Judging from the overall development of the hybrid vehicle industry, Japanese brands represented by Toyota and Honda almost occupy most of the hybrid vehicle market, except Ford and GM, which were the first American car companies to participate in the research and development of hybrid technology.
Statistics show that as of 20 17, more than 100 hybrid vehicles have been developed in the world, most of which are from American and Japanese automakers.
It was like this three years ago, not to mention now?
However, with the release of Great Wall Motor's "lemon hybrid DHT" technology, the slow layout of independent brands in the field of hybrid technology will undoubtedly be improved.
In this regard, Great Wall Motor is also more confident. "There is a saying in the Great Wall:' Only China people know the mixture of China people best.' Because we are independent brands, we are both car developers and users, and we know what the general working conditions of China people are like, unlike Japanese or Europeans. "Feng Mu said.
Fu Shuo, honorary chairman of China Automotive Engineering Society, said: "Developing hybrid power is a national mission and imperative. Great Wall Motor's move is of great significance, and the release of lemon mixed DHT is worth learning and learning from the industry. "
When talking about the strength of "lemon hybrid DHT" technology, Shan Hongyan, vice president of Great Wall Motor R&D, compared "lemon hybrid DHT" technology with mainstream Japanese hybrid technology. She said: "Compared with Nissan series, Honda series-parallel connection and Toyota power split, lemon hybrid DHT has advantages in alertness and power in full speed range and full scene road conditions."
Shan Hongyan, vice president of Great Wall Motor R&D, and four industry experts discuss the present and future of hybrid technology.
Regarding the release of Great Wall Motor's "lemon mixed DHT" technology, Li Qingwen, president of the Automobile Evaluation and Research Institute, said: "China brand must have excellent technical strength if it wants to go global. Obviously, Great Wall Motor is working hard in this direction. "
