Today is the second article of our "Great Wall Motor 2021" article, we will sort out the layout and thinking of Great Wall Motors in the field of new energy.
In 2020, the world's automotive industry can be said to have reached a consensus on full electrification, and in 2021, domestic new energy vehicle sales reached 3.521 million units, an increase of 1.6 times year-on-year, and China's new energy vehicle market completed the transformation from policy-driven to market-driven.
The dual-carbon target of "achieving carbon peaking by 2030 and carbon neutrality by 2060" established by the mainland has further accelerated the pure electric trend of the industry.
Under the background of the mainstream automobile enterprises in the world today, great wall motors have adopted a multi-track route - pure electric, hybrid, hydrogen power three mainstream technology directions full coverage.
In another area that cannot be ignored - the field of internal combustion engine, in 2021, Great Wall Motors released a 3.0T+9AT/9HAT super powertrain, and the performance data is comparable to the world's first-class engine, and even surpassed.
Great Wall Motors promotes four power routes at the same time, and is one of the few automobile brands in the industry with multiple tracks. The active layout of the new energy industry chain has made it one of the enterprises with the widest layout in China.
Multi-track layout, "pragmatic" but also "courageous"
Why does Great Wall Motors have such a choice? In the eyes of zhi qijun, there are two reasons.
First, based on the pragmatism of "technical strategic security", on the basis of a clear understanding of its own development stage, plan an electrification route;
Second, based on the innovation wave of the transformation of China's auto market, we use our own fortress and capital market to boldly lay out.
Pragmatically, Great Wall Motors realized that the internal combustion engine is still the core technology that determines the performance of a car. In the past six years, Great Wall Motor's annual sales have exceeded one million consecutively, and in 2021, it exceeded 1.28 million units, of which the sales volume of new energy vehicles reached 136,900 units, accounting for 10.7%, achieving a record high.
However, at this stage, the "cash flow" mainly comes from fuel vehicles, which are still the foundation of Great Wall Motors, and every improvement in its internal combustion engine performance indicators will strengthen its competitive advantage with the joint venture brand.
Therefore, It is pragmatic and fundamental for Great Wall Motors to maintain continuous large-scale investment in internal combustion engines.
But the timetable for carbon peaking and carbon neutrality is at hand, the time is equally tight, the future of the internal combustion engine is clearly visible, will the simultaneous promotion of fundamental and electrification divide the limited resources of Great Wall Motors?
This reflects the "courage" side of Great Wall Motors.
On the one hand, the upgrading of internal combustion engine technology has laid the cornerstone for hybrid technology, making full use of the transition cycle and reducing carbon emissions;
On the other hand, the full-line layout of the new energy vehicle industry chain has overcome the core technology and made the product line from the economy to the high-end market.
Carbon neutrality is system engineering, which requires all automotive companies to carry out a comprehensive energy-saving and emission-reduction planning layout around the whole life cycle of the vehicle.
On the one hand, Great Wall Motors builds zero-carbon factories and adopts the "automobile industry recycling system", on the other hand, it accelerates the construction of new energy core technologies and related industrial chains with a more strategic layout.
In the field of core technology, Great Wall Motors has demonstrated its independent research and development strength in the three directions of pure electric, hybrid and hydrogen power, and has demonstrated many new technological achievements that break many technical barriers.
Hybrid architectures are diverse, led by Lemon Hybrid DHT
In the field of hybrid technology, Great Wall Motors has launched lemon hybrid DHT technology, which has been mass-produced and installed on Wei brand Macchido DHT, Wei brand latte DHT, Haval Chitu DHT and other models.
Using the two-motor hybrid technology of lemon hybrid DHT, the comprehensive fuel saving rate of urban working conditions has reached 50%, the comprehensive fuel consumption of the whole vehicle is as low as 4.6L/100km, and it covers both HEV and PHEV architectures. Among them, the pure electric mileage of PHEV models can reach 200km, and the total cruising range can reach 1100km, which has obvious advantages in the current car market.
According to the plan, the second generation of lemon hybrid DHT is expected to be released in 2023, through engine thermal efficiency upgrades, hybrid system configuration and parts optimization, can further reduce the vehicle fuel consumption by more than 15%, increase power by 20%, and increase cruising range by 50%.
In addition, on the tank platform of Great Wall Motor's off-road platform, in 2022, it will also launch a longitudinal P2 hybrid architecture, equipped with a self-developed 3.0T engine (3.0GDIT engine + 9AT P2 PHEV). The thermal efficiency of this power combination reaches the highest level of 38% of the same displacement, and together with the high-efficiency motor system, the maximum power reaches 380 kW and the maximum torque is up to 750 Nm. In off-road 4L mode, the climbing ratio can reach 57:1 and the fuel saving rate can reach 25%.
By then, tank platforms are expected to be the most powerful off-road platforms in the world.
This technology can ensure that Great Wall Motors obtains sustained and stable cash flow for a period of time, and establishes an economic foundation for its comprehensive electrification transformation.
Pure electric technology to achieve closed-loop, the core technology of the whole chain of self-research
In terms of pure electric drive technology, Great Wall Motors has a layout in the fields of battery, electric drive and electronic control. Its Hive Energy has advanced technologies such as L-type long batteries and LCTP moduleless technology.

It is worth pointing out that Great Wall Motors has opened dayu battery technology to the society for free technical patents, reflecting its responsibility to promote the development of technology in the whole industry.
At the same time, in order to completely solve the problem of thermal runaway battery, Great Wall Motors has also created a safer "jelly battery" through innovative technology combinations such as safety coating, flame retardant electrolyte, and jelly electrolyte in battery technology.
Solves the battery safety problem that is most concerned in the new energy vehicle market.
Focusing on the four dimensions of "integration, high voltage, high speed and high efficiency", Great Wall Motors already has 35kW to 220kW series products in the field of motors, which can cover A00 to D-class models.
According to official information, its newly developed 220kW high-power T-type bridge adopts 13 key technologies such as dry oil pan and circulating oil channel, with a maximum efficiency of up to 95% and a power density of 2.4kW/kg, which has reached the current industry's outstanding level.
While developing the three-electric system, Great Wall Motors has also prospectively laid out power battery recycling technology to cope with the environmental challenges brought by the popularization of new energy vehicles.
At present, Great Wall Motors has built a perfect battery recycling system, decommissioned batteries and battery production process of scrap batteries, polar coil waste, can be recovered through the Great Wall Motors recycling network, disassembled and broken, through hydrometallurgy to extract sulfate, lithium carbonate, and then made into precursor and cathode materials, forming a recycling closed loop.
With this system, it will provide a reference model for the new energy automobile industry, greatly alleviate the pressure on environmental protection caused by the increasing number of waste batteries, and promote the benign development of the industry.
At the market end of pure electric vehicles, Great Wall Motors already has two pure electric brands, one is Euler, and the other is the salon that debuted at the Guangzhou Auto Show on November 19, 2021.
Among them, Euler has exceeded the annual sales of 135,000 vehicles in 2021, and the annual sales of its good cats and black cats have exceeded 50,000 and 60,000 vehicles respectively, and are moving towards the goal of "achieving global production and sales of 1 million vehicles by 2023".
Sharon is positioned in the high-end market, the goal is to become the first brand of luxury pure electricity in China between 400,000 and 800,000 yuan, and will adopt the Internet-based enterprise operation model to pursue a higher-end, more luxurious and more intelligent.
Its first model will be launched in 2022, and will cover sedans, SUVs, sports cars and other categories in the future.
Hydrogen power breaks through technical barriers and helps Great Wall Motors blossom at multiple points
In the field of hydrogen power technology, Great Wall Motors has also landed a series of new technologies and achievements in 2021.
In March 2021, Great Wall Motors officially released its hydrogen energy strategy, and Great Wall Motors announced the establishment of an international-level "production-storage-transportation-plus-application" integrated supply chain ecology.
At the same time, the vehicle-level "hydrogen power system" full-scenario solution - hydrogen lemon technology was also officially released; in August 2021, the world's first 100 49-ton hydrogen energy heavy truck project was put into operation, and successfully joined the national fuel cell vehicle demonstration city cluster such as Beijing and Shanghai; in October 2021, the completely self-developed new high-performance membrane electrode achieved mass production, promoting the large-scale application of fuel cell technology; in December 2021, the "Beyond - Shenzhou 200" high-power fuel cell engine was unveiled. And released a new generation of hydrogen magic box, fuel cell intelligent detection technology "NORDS (NODS) cloud doctor", 70MPa multi-functional integrated pressure reducing valve group "Iogenjik" series of products.
Such an intensive technology release is rare in Chinese car companies, and its technical strength can be seen from this.
Among them, the most concerned is undoubtedly the release of hydrogen lemon technology, which has realized the complete autonomy of six core technologies and product intellectual property rights of "stack and core components, fuel cell engines and components, four-type hydrogen storage cylinders, high-pressure hydrogen storage valves, hydrogen safety assessment, and liquid hydrogen process".
With these new technologies breaking through technical barriers, it means that in the field of hydrogen fuel, China's key technologies are no longer subject to people, and Great Wall Motors has officially entered the international front-line camp in terms of hydrogen power.
At present, Great Wall Motor's Untax Energy claims to have mastered a full set of key hydrogen energy technologies such as fuel cell engines, stacks, membrane electrodes, and hydrogen storage systems, and has set the goal of "reaching the top three in the global hydrogen energy market share by 2025".
