On the 30th anniversary of the Great Wall, I gave myself three gifts-lemon, tank and coffee intelligence, which respectively correspond to the global high-intelligence modular technology platform, the global intelligent professional off-road platform and the intelligent system for future travel.
Among them, the lemon platform, as a global high-intelligence modular technology platform, lasted for 5 years and cost 20 billion yuan to build. Focusing on the future 10, it has four power schemes, including four high-efficiency fuels/hybrid/hybrid electric/hydrogen energy, and three hybrid special engines.
Near the end of the year, Great Wall Motor lemon platform once again made a big move-lemon mixed DHT. This is a highly integrated, efficient and multi-mode hybrid power system, which adopts the series-parallel hybrid power technology of two motors. This technology can be applied to HEV and PHEV, covering three powertrains and supporting all levels of vehicles.
What are the advantages of lemon hybrid DHT, how is it different from Japanese hybrid technology, and how does it affect the development of independent brand hybrid field? These three questions can be found in this paper.
Lemon hybrid DHT is a "seven-in-one" hybrid power system consisting of 1.5L/ 1.5T hybrid engine, fixed-axis gearbox, integrated DCDC, GM/TM dual motors and dual motor controllers. It can realize EV, series connection, parallel connection and energy recovery, and has three characteristics of high integration, high efficiency and multi-mode oil-electricity mixing.
Lemon hybrid DHT can be divided into two hybrid forms: HEV (Hybrid Electric Vehicle) and PHEV (Plug-in Hybrid Electric Vehicle), which can support flexible matching of different classes of vehicles. Specifically, HEV focuses on the ultra-low fuel consumption of urban road conditions and the instantaneous acceleration ability of medium and high-speed road conditions, and the comprehensive efficiency of the power system can reach more than 50%.
Among them, the power of 1.5L hybrid engine +DHT 100 power system is 140kW, and the comprehensive fuel consumption of A-class SUV is as low as 4.6L/100km; 1.5T hybrid engine +DHT 130 power system can reach 180kW, used in? On the B-class SUV, compared with the fuel products, the fuel saving rate can reach 35~50%, and the acceleration time of 0- 100km/h is greatly shortened 1.5s, only 7.5s, which realizes both fuel consumption and power.
I guess the third generation Haval H6 and Haval Big Dog are based on the Great Wall Lemon Platform, and they are also the third generation Haval H6 in the test drive. These two cars are expected to launch a hybrid version first.
In addition, PHEV has "1.5T? The +DHT 130+P4 "four-wheel drive powertrain uses a battery with a larger capacity (the battery with a maximum capacity of 45kWh), and the system power also reaches 320KW. It is understood that the acceleration time of the model equipped with this power system is only 5.2 seconds, and the pure electric cruising range will exceed 200km, which will be applied to higher-level models in the future.
When it comes to hybrid electric vehicles, we always think of Toyota THS and Honda i-MMD. In China market and even the whole world, Nida hybrid electric power is excellent and a benchmark in the industry. Because THS and i-MMD are excellent hybrid power systems, latecomers can't surpass them (no better solution can be found). What are the advantages of Great Wall lemon hybrid DHT?
Compared with Toyota's THS hybrid system, the Great Wall lemon hybrid DHT is closer to Honda's i-MMD hybrid system in working mode, but the former has better performance.
The direct drive part of the Great Wall lemon hybrid DHT engine was changed to two gears, and a set of shifting mechanism was added, which obviously emphasized the direct drive ability and the timing of the engine, mainly reflected in the comprehensive efficiency output of the power system.
In other words, the Great Wall lemon hybrid DHT will give the engine more protagonist performance (the opportunity to directly drive the wheels), instead of playing a supporting role in most cases (generating electricity by driving the generator motor, and then driving the wheels by the driving motor). Its advantage is not only that the power performance will be stronger, but also that the fuel consumption performance will be more impressive due to the reduction of loss.
According to the Great Wall official introduction, this hybrid system was developed three years ago. It is completely designed and developed by Great Wall Motor, with completely independent intellectual property rights, and has accumulated 199 patents, including 80 core patents.
According to this statement, Great Wall Motor bypassed the patents of hybrid technology in Japan and Tianjin, and achieved a breakthrough in HEV technology in another way.
Although independent brands have developed well in the field of new energy, and pure electric and plug-in hybrid electric vehicles are in the forefront of the industry, they are still in a state of "waiting to start" in the field of hybrid electric vehicles (HEV).
Great Wall Motor released lemon hybrid DHT technology, which can be said to be a breakthrough of domestic brands in the field of oil-electricity hybrid from scratch, and will also drive other powerful independent brands to accelerate research and development, thus driving the entire independent brand to achieve technological progress and brand progress.
For Great Wall Motor, there is no doubt that there is another trump card in hand. Playing this trump card, China's oil-electricity hybrid market may be changed. In other words, the hybrid of oil and electricity is no longer the world of Toyota and Honda, and Great Wall Motor will come in and share a piece of it. Of course, the premise is that the actual performance of the Great Wall lemon mixed DHT should be as good or better than what was said at the press conference.
At the same time, although Great Wall Motor has a high sales volume and a good comprehensive reputation, its fuel consumption has remained high. When lemon hybrid DHT technology is fully introduced into fuel vehicles, it will turn all the previous disadvantages into the most eye-catching advantages and help its product sales continue to climb.
In addition, in June of this year, 5438+ 10, the Technical Roadmap for Energy-saving and New Energy Vehicles 2.0, which was directed by the Equipment Industry Division I of the Ministry of Industry and Information Technology and organized by the China Automotive Engineering Society, was officially released. It was clearly mentioned that by 2035, all traditional energy-powered passenger cars will be converted into hybrid vehicles, and the annual sales of hybrid vehicles and new energy vehicles (pure electric vehicles, plug-in hybrid vehicles and fuel cell vehicles) will each account for 50%.
The Great Wall lemon mixed DHT also has a policy guarantee. It can even be said that in the next 15 years, hybrid technology will be very popular.
With the release of Great Wall lemon hybrid DHT, its lemon platform models will also introduce this technology one after another to comprehensively enhance the market competitiveness of products.
Of course, the Great Wall with rapid technological upgrading is a microcosm of the upward development of independent brands at present. At this time, independent brands have not only relied on high-value design and rich configuration forms to enhance their brand strength, but also turned to the research and development strength of core technologies, and achieved brand progress through hard core and advanced technologies. Today's independent brand should be worthy of our thumbs-up!
