Huawei has invested heavily in cutting-edge scientific research, and the return is difficult to see in the short term. Ren Zhengfei said:
"Let the bullets fly for a while".
Today, the energy-saving and new energy technologies of major car companies have blossomed. Tracing its origins, competitive, are "bullets that have flown for a long time". Great Wall Motors, hybrid, pure electricity and hydrogen energy three-way go hand in hand, the products have been on the road, to see the sales of sales, to see the effect of the effect. They are all "bullets that have flown for a long time" of Great Wall Motors:
Pure electricity: at the beginning of the 21st century, we began to pre-develop models, pushed pure electric concept cars in 2008, and pre-developed battery cell projects in 2012;
Hybrid: Layout research and development began in 2012, and the development of DHT system was officially opened in 2018;

The Great Wall is known as the king of SUVs and the king of pickup trucks. Its scientific research main channel, in addition to the traditional engine, gearbox, transmission, body... It has always included energy-saving and new energy vehicle technologies.
At a time when the whole industry and the whole society are focusing on the peak and carbon neutrality of automobile carbon, these technical reserves of Great Wall Motors have been transformed into products and become a weapon to enhance sales and profits.
01
Pure electricity first
In 2021, Euler sold another 135,000 units, up 140% year-on-year.
Euler began selling cars in 2018, benefiting from Great Wall Motors' energy-saving and new energy vehicle technologies at the earliest.
In fact, at the 2008 Beijing Auto Show, Great Wall Motors exhibited the concept car Euler pure electric and began to try to productize pure electric technology.
In the past decade, Great Wall Motors has established a number of technology research and development centers in North America, Europe and Asia, bringing together intelligent electric vehicle R&D experts from more than 40 countries to divide labor research and development. On the power battery alone, it has invested more than 1 billion yuan to build a battery cell, mechanism analysis, PACK, BMS trial production laboratory, etc.
In terms of battery pack technology, Great Wall Motors continued to develop and released Dayu battery technology. As the name suggests, "Dayu Battery" adopts the thermal management strategy of the battery pack that is "blocked as bad as thin", which can make the battery pack have excellent safety performance of not firing and not exploding at a high temperature of 1000 °C.

In terms of the other two items of Sanden - motors and electronic control, Great Wall Motors is also independently developed, and its cost performance is internationally leading. The products can meet the power needs of A00 to D class passenger cars, as well as pickup trucks and logistics vehicles.
The "bullet" flew for ten years, and once it was launched, the results were amazing.
Nowadays, in terms of pure electric brands, the Sales volume of The Great Wall's Euler is at the forefront of the industry, and the explosion of models continues, and the brand is grand.
In addition, at the 2021 Guangzhou Auto Show, Great Wall Motors launched a pure electric high-end brand - Salon, and released the first high-performance mech battle sports mecha dragon.
The Salon brand has also been continuously empowered by the pure electric technology of Great Wall Motors, and the first model, the Mecha Dragon, uses Dayu battery technology.
Under the blessing of such technology, the mecha dragon not only has excellent safety performance of 1037 °C high temperature no fire and no explosion, but also has zero hundred acceleration 3.7s, CLTC endurance of 802km, the world's leading 800V/480kW high-efficiency energy replenishment technology and associated APA wireless charging function, etc., which will raise the performance of electric vehicle products to a new high.
Cobalt-free batteries are already on the market
It can be said that in the three major energy-saving and new energy vehicle technical routes of Great Wall Motor's pure electricity, hybrid and hydrogen energy, the pure electric route is the earliest to blossom and bear fruit.
02
Hybrid technology is scenario-based
At the 2021 Guangzhou Auto Show, the Great Wall Motor Wei brand released a smart mix strategy.
On the same day, Macchiato DHT-PHEV was launched.
On January 14, 2022, Mocha DHT-PHEV was released for pre-sale.
The latte DHT-PHEV is expected to be released in the first half of 2022.
Wei brand three major models: latte, mocha, macchiato all series of hybrid development step by step.
In 2021, Weipai sold 58,400 vehicles in the whole year. In particular, in December, driven by lemon hybrid DHT products, Wei brand sold well in the new energy market, helping the total sales volume reach 10,065 units, an increase of 60% month-on-month.
The official development of Great Wall Motor's lemon hybrid DHT system began in 2018, but the application was released in 2020, and it took only 2 years.
Why so fast?
Huang Zhenyang, chief engineer of the hybrid system of Great Wall Motors, replied: "Because the Great Wall has laid a very good foundation. ”
The so-called foundation can be seen from time - Great Wall Motors began to layout hybrids in 2012.
Wei Jianjun, the founder of Great Wall Motors, hopes that one day China's hybrid technology can catch up with and surpass Japanese hybrids. It was also in 2012 that he decided to formally set up a project to develop hybrid technology.
In the past eight years, Great Wall Motors has completely relied on independent design and completely independent research and development, and launched hybrid technology with completely independent property rights.
The lemon hybrid DHT technology developed on a good basis is a blockbuster.
The technical characteristics of lemon hybrid DHT can be summarized as "1-2-3":
1 set of highly integrated hybrid system, according to the working conditions, automatically switch pure electricity, series, mixed, energy recovery and other working modes;
2 power forms, HEV and PHEV two power architectures, can meet the power manufacturing needs of different models;
3 powertrains, 2-wheel drive HEV, 2-wheel-drive PHEV and 4WD PHEV.
Take the latte DHT as an example, its DHT hybrid is the industry's first two-stop hybrid system, 0-60km/h acceleration time only 3.9 seconds, 100 km acceleration 7.5 seconds, 100 km comprehensive fuel consumption of 4.9L. The comprehensive mileage exceeds 1000 kilometers, which completely helps users bid farewell to endurance anxiety, and the cost of comprehensive vehicles is close to pure electric models, and the real sense of "the same price of oil and electricity" has been achieved.
Speaking of hybrids, it must be compared with Toyota hybrids.
In the most traditional skills - engines and gearboxes, Great Wall Motors Lemon Hybrid DHT is not at all inferior.
Like the engine in the 1.5T lemon hybrid DHT system, the maximum power is 115kW, which can be matched with the 130kW DHT module, and the system has a comprehensive power of 180-240kW. It features Miller cycles and is equipped with a VGT supercharger, which improves dynamic responsiveness by 30 percent, low-speed torque levels by 16 percent, and enables a quick warm-up function due to the integrated exhaust manifold on the cylinder head, better adapted to the technical needs of hybrid vehicles.
The outstanding performance of the engine in the 1.5T lemon hybrid DHT system made it win the "Heart of China" award for the top ten engines of the year in 2021.

In addition, the lemon hybrid DHT module acts like a gearbox on a fuel vehicle, and inside the DHT module, there is an integrated reducer, clutch, shift mechanism and dual motors, and for the first time, a dual-gear design is used.
This innovation has enabled Great Wall Motor's lemon hybrid DHT to win the honor of "World's Top Ten Transmissions".
In addition, Great Wall Motor Lemon Hybrid DHT has the following advantages over Toyota Hybrid.
First, compared with Toyota's hybrid, Great Wall Motor's lemon hybrid DHT has an advantage in the total power of the system, so the acceleration is faster;
Second, in the lemon hybrid DHT plug-in system, the battery pack of the PHEV has a large amount of power, so it has a long pure electric endurance, far exceeding the Toyota plug-in hybrid;
The Lemon Hybrid DHT transmission integrates a double-speed transmission, allowing the engine to run in more efficient scenarios and be more efficient...
As Weipai CEO Li Ruifeng said: "Different from the Japanese hybrid improvement idea, Lemon Intelligent Hybrid DHT technology has truly achieved leading innovation and structural change, and achieved efficient operation of the full-speed domain." ”
From the perspective of "Electric Vehicle Observer", the Great Wall Lemon Hybrid DHT system not only makes up for the shortcomings of Chinese brands in the field of engines and gearboxes, but also uses the combination of pure electric technology and dimensionality reduction applied in China to create a hybrid solution that is more suitable for Chinese scenarios. Its use experience is closer to pure electricity, and it has the advantage of energy consumption while also giving abundant power.
In addition to the intelligent DHT hybrid system already applied on Weipai's "three cups of coffee", Great Wall Motors has also developed an extreme performance hybrid system and a powerful off-road hybrid system.
The extreme performance hybrid system adopts the front-wheel drive system of 2.0T high-performance engine + 9HDCT and the high-performance rear wheel pure electric drive axle to make full use of the extreme adhesion of the four wheels to provide the ultimate sports experience.
The powerful off-road hybrid system adopts V6 3.0T engine, 9HAT gearbox, 4L/4H two-speed intelligent four-wheel drive system, with a climbing ratio of 57.2:1 and a fuel saving rate of more than 25%, which can provide users with a strong power experience and off-road fun.
The hybrid technology of these three scenarios can make all kinds of models of the Great Wall - SUVs, hardcore off-road vehicles and pickups - reduce fuel consumption and meet the needs of different users under the premise of abandoning power.

Hydrogen energy: laying out the future
In 2016, a German named Tobias Brunner came to Baoding.
Tobias Brunner was in charge of hydrogen fuel cell development at BMW. He joined Great Wall Motor as Vice President, with the goal of developing hydrogen energy technology.
Since then, Great Wall Motors has successively invested 2 billion yuan in research and development expenses for hydrogen energy technology, and established a global R&D center in Baoding, Shanghai, Canada, Japan and Germany, with a core team of 430 people.
In 2018, Great Wall Motors also acquired the old fuel cell technology company Shangburn Power to further consolidate its research and development strength.
On-combustion power beyond - Shenzhou 200 fuel cell system
In March 2021, Great Wall Motors held a global press conference on hydrogen energy strategy, unveiling the veil of Great Wall Motor's hydrogen energy strategy.
Great Wall Motor's hydrogen energy strategy is not limited to hydrogen fuel cell vehicles, but covers the integrated supply chain ecology of "production-storage-transportation-addition-application", and at the same time launches a set of vehicle-level "hydrogen power system" full-scenario application solution - hydrogen lemon technology.
In terms of R&D investment, Great Wall Motors will invest another 3 billion yuan in research and development in the field of hydrogen energy to achieve 10,000 sets of production capacity.
In the upstream of the industrial chain, Great Wall Motor's new generation of perovskite solar photovoltaic technology has a world record-breaking 20.01% photoelectric conversion efficiency, marking a large-area perovskite photovoltaic module conversion efficiency officially entered the "2.0 era". In terms of large-scale energy storage applications, the industry's leading hydrogen + electric energy storage system provides solutions for large-scale renewable energy storage, laying the foundation for the comprehensive utilization of mobile and stationary energy.
Perovskite photovoltaic modules
In the downstream of the industrial chain, Great Wall Motors has joined the four demonstration pilot city clusters of Beijing-Tianjin-Hebei, Yangtze River Delta, Henan and Hebei, with more than 1,000 demonstration vehicles planned, involving passenger cars, heavy trucks, logistics, buses, ships, rail transit and other application scenarios, drawing a broader market blueprint.
These R&D layouts and investments will help Great Wall Motors realize its hydrogen energy strategy in three steps:
The first stage, 2021-2025, will open the hydrogen era and focus on hydrogen demonstration.
The second stage, 2025-2035, is to develop a hydrogen economy and open up the hydrogen ecology.
The third stage, 2035-2050, is to build a hydrogen society and contribute to carbon neutrality.
Eventually, Great Wall Motors will become an ecological operator for hydrogen energy production, storage and comprehensive utilization.

Three ways go hand in hand, the road leads
The pressure on the environment and energy is increasing, and the perception of the people is getting deeper and deeper.
All car companies are facing consumers' experience demand for energy-saving and new energy vehicle technologies, cost reduction needs, and also face the needs of carbon reduction in industry management.
For Great Wall Motors, because the products are mainly pickup trucks and SUVs, the use scenarios are rich and diverse, so the energy saving and emission reduction solutions required cannot only be one.
As a result, Great Wall Motors has invested heavily in the three technical routes of pure electricity, hybrid and hydrogen energy to provide a wide range of solutions.
Among the private car companies, Great Wall is the only one to do so.
Its effectiveness can be said to be three ways to go hand in hand, and the road is leading:
In the key indicators of pure electric technology - safety, energy density, fast charging performance, supply stability, Dayu battery technology, honeycomb high-nickel ternary battery, 800V/480kW high-efficiency energy replenishment technology, cobalt-free, lithium iron phosphate battery have given the industry's most competitive solutions, some are still the industry's first.
In terms of the key indicators of hybridization - efficiency, performance, and scene adaptability, the Great Wall hybrid efficiency is in line with Toyota, the performance is better, the scene adaptability is richer, and it can better meet the needs of consumers in a variety of car scenes.
In terms of the key elements of hydrogen energy - independent controllability, industrial application and ecological support, Great Wall Motors has not only mastered the core technology, but also vigorously promoted the commercial application of hydrogen energy vehicles, and also has a wide layout in the upstream and downstream of hydrogen energy, and will become a full ecological supplier of hydrogen energy in the future, with a far-reaching pattern.
Previously, the main channel of Great Wall Motor's research and development of energy-saving and new energy vehicles was wide and clear. The bullets produced by these research and development will also continue to provide explosive power to break through the siege for Great Wall Motors' carbon peak and carbon neutrality after flying for a while.
