As Wei Jianjun, chairman of Great Wall Motors, wrote in "Can Great Wall Motors survive next year?" 》said:
“If we think we have succeeded, every successful past may hinder the future; if we still cannot see disruptive changes, those who have been subverted will It must be us; if we dare not break the rules, then the rules will soon become a prison for creation."
Great Wall Motors has always been committed to continuous innovation in core technologies, from lemons to tanks. From the release of the three major coffee smart technology brands to the rollout of the new generation powertrain, Great Wall Motors has been making continuous breakthroughs and upgrading.
On December 15, Great Wall Motors officially made its world premiere at the Haval Technical Center in Baoding. The "Lemon Hybrid DHT" technology for the full speed range and all scenarios is aimed at the highly influential company in the hybrid field. Japanese Ryota represents independent brands and breaks the monopoly of joint venture technology.
"Lemon Hybrid DHT" stands for "Dedicated Hybrid Technology". It uses dual-motor hybrid technology, one for power generation and one for drive, and two-speed transmission gears. It covers almost all travel scenarios such as medium and low-speed travel on urban roads, long-term parking, high-speed/urban loops, etc., and can bring users lower fuel consumption, stronger power, and a more comfortable travel experience.
For reference: Toyota Twin Engine: No direct drive capability. Honda immd: high-speed first gear direct drive. Great Wall DHT: two-speed direct drive.
From a technical perspective, the forward-looking and advanced technology of Lemon Hybrid DHT is reflected in the "1-2-3" (one hybrid system, two power architectures, three sets of powertrains) into) on.
Mu Feng, Vice President of Product Strategy and Technology R&D of Great Wall Motors, explains the "Lemon Hybrid DHT" technology strategy
A hybrid system refers to the "Lemon Hybrid DHT" using dual The motor hybrid topology has multiple working modes such as pure electric, hybrid, series, and energy recovery. Through intelligent switching of the control system, it can achieve a perfect balance of high efficiency and high performance in the full speed range and in all scenarios.
The two power architectures refer to the two power architectures of HEV/PHEV based on the dual-motor hybrid topology and in the face of different consumer demands.
HEV architecture, compared to Toyota, Great Wall's HEV not only focuses on fuel economy, but also emphasizes power performance. It focuses on ultra-low fuel consumption in urban road conditions and instant acceleration capabilities in medium and high-speed road conditions. The comprehensive efficiency of the power system can reach more than 50. The comprehensive fuel consumption of an A-class SUV powered by HEV is as low as 4.6L/100km.
In actual tests, taking the HEV architecture B-class SUV as an example, compared with fuel products, the fuel saving rate can reach 35~50, and the 0-100km/h acceleration time is significantly shortened by 1.5 seconds, only 7.5s, achieving victory in both fuel consumption and power.
Schematic diagram of the main components and operating modes of the "Lemon Hybrid DHT"
PHEV architecture, equipped with a large-capacity and high-efficiency hybrid battery of 45 kilowatt hours. The battery is indeed large, unlike other Plug-in hybrid models place the battery on the rear axle, but place the battery under the floor like an electric vehicle. The most direct benefit is simple and crude: its PHEV model has a pure electric range of up to 200km!
What is this concept?
Leave aside the fact that the EV range of PHEV models in the existing market can only hover around 50km. Even for pure electric models, there are still models with an EV range of less than 200km!
Great Wall Motors’ PHEV is really amazing!
Three sets of powertrains refer to the two architectures of HEV/PHEV. The engine has two hybrid-specific Atkinson cycle models, one 1.5 self-priming and one 1.5T. According to Three types of hybrid power systems are composed of different engines. The total system power ranges from 140kW to 320kW, which can provide high coverage for A-B-C class vehicles.
The first type: 1.5L hybrid dedicated engine DHT100 (100kW highly integrated hybrid transmission), which can realize HEV/PHEV two power sources and is mainly used in A-class models;
The second type: 1.5T hybrid special engine DHT130 (130kW highly integrated hybrid transmission), which can realize HEV/PHEV two power sources, and is mainly used in B-class models;
The third type: 1.5 T hybrid special engine DHT130 P4 (135kW three-in-one two-speed electric drive rear axle), which can realize PHEV power and is mainly used in C-class models;
Based on this, "Lemon Hybrid DHT" can serve It has a high degree of flexibility for users in different regions and with different needs around the world.
After thirty years of hard work, Great Wall Motors has grown from a small local factory in a corner to a leading Chinese automobile company with annual sales of one million for four consecutive years. It dares to think and fight hard, is good at finding light in adversity, and is even better at finding shadows in good times.
In an era when the global economy is in recession, dividends are about to run out, and foreign brands and new car-making forces are fighting each other, Great Wall Motors has prepared for a rainy day. As early as two or three years ago, it had laid out this hybrid technology and worked with it. The recently released "Energy Saving and New Energy Vehicle Technology Roadmap 2.0" emphasizes "increasing hybrid investment and expanding the hybrid market" and is highly consistent with it.
The entire set of technology is completely independently designed and developed by Great Wall Motors, and has completely independent intellectual property rights. It has 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 enjoy the technical division of labor and cost-effectiveness dividends brought by the global division of labor, but also avoid being stuck in key technologies and ensure Iterative updates and sustainable development of technology research and development.
Its release completely broke the long-term monopoly of joint venture brands in the hybrid field, set a new benchmark for China's hybrid technology, rectified the name of the "Great Wall of Science and Technology" and "Created in China".
Shan Hongyan, Vice President of R&D of Great Wall Motors, and four industry experts*** discussed the present and future of hybrid technology
This also means that Great Wall Motors has once again made great progress in core technologies. Ushered in a historic breakthrough, which further consolidated the technological foundation of Great Wall Motors' global development and became an important support in the globalization strategy.
After thirty years of hard work and hard work, Great Wall Motors has always insisted on leading the brand with technology and driving development with innovation. Today, when the automotive industry is undergoing rapid changes, "Lemon Hybrid DHT" reflects Great Wall Motors' comprehensive consideration of the coordinated development of energy, environment, and people and vehicles, and shows that Great Wall Motors is at the forefront of the global wave of hybrid technology research and development.
Everything is ready. Relevant personnel revealed that hybrid models equipped with "Lemon Hybrid DHT" will be launched next year. Currently, Haval H6 has a Hev hybrid version in road testing. Interested If you are a cyclist, you might as well join me and take a look. I believe the Great Wall will not let you down.
