Before 2020, if we want to buy a hybrid model, we can probably only consider the Japanese two fields. It was not until the end of 2020 that the state released the new energy route 2.0 and independent brands successively released hybrid strategies and technologies that consumers had more choices.
In the past year, the DHT hybrid model launched by Great Wall Motor has become the first choice of many consumers. "SUV experts" in the field of new energy to achieve explosive growth, Great Wall Motors "buried in hard work" what?
Lemon hybrid DHT technology, "tip of the iceberg"
In the eyes of many people, lemon hybrid DHT technology is "born out of nowhere". After the official release in December 2020, Great Wall Motors launched five new hybrid models in a row in the following year, including the WEY brand mocha DHT-PHEV, Macchiato DHT/DHT-PHEV, latte DHT, Haval brand H6S-DHT, and Red Rabbit DHT. With the help of lemon hybrid DHT technology, the WEY brand has also completed the hybrid transformation of the entire series.
A number of hybrid models have entered the field of vision of consumers, and everyone has found that Great Wall Motors has been "competing" in this technology for a long time, but this is only the "tip of the iceberg" of Great Wall Motors' technical assets.
Lemon Hybrid DHT is a highly integrated multimode oil-electric hybrid system that supports HEV oil mixing and PHEV plug-in hybrid; compact and mid-level vehicles apply 1.5L hybrid and 1.5T hybrid respectively, and medium- and large-sized vehicles such as WEY Mocha DHT-PHEV also provide high-performance 1.5T plug-in hybrid four-wheel drive. A set of systems derives a variety of power combinations and adapts to different levels of models, which is a full-scenario and efficient application scheme proposed by Great Wall Motors after studying the diversity of Chinese consumer cars.
The drive system is the basic strength of the lemon hybrid DHT. Great Wall Motor's self-developed hybrid 1.5L and 1.5T engines cover the 140-240kW power range, and the overall efficiency is as high as 50%. The 1.5L engine is mated to a 100kW hybrid transmission and can achieve fuel consumption as low as 4.6L/100km on compact SUVs. The 1.5T engine is mated to a 130kW hybrid gearbox, optimizing both performance and energy savings on mid-range vehicles. Taking WEY Latte DHT as an example, zero hundred acceleration of 7.5 seconds, 100 km fuel consumption is only 4.9L, compared with the same level of models, the advantages are obvious.
Hybrid mode is where the differences and advantages lie. The Lemon Hybrid DHT innovatively uses a two-speed transmission, which can realize the free switching of pure electricity, series, parallel, and energy recovery modes based on different scenarios and different speed domains. For example, under urban conditions, pure electricity or series mode is directly driven by the motor, which maximizes energy saving effect and driving comfort; while the parallel mode under high-speed or climbing and large load conditions is directly driven by the engine and adjusted by motor assistance, taking into account power and fuel consumption.
To put it simply, Great Wall Motor's lemon hybrid DHT allows a hybrid vehicle to obtain a variety of hybrid effects - the engine energy efficiency is poor to the motor, and when the motor is not working well, let the engine join, the system intelligent control mode switching, in various driving scenarios, lemon hybrid DHT can provide a perfect balance of power and fuel consumption.
Therefore, when several models equipped with lemon DHT enter the terminal market, consumers are quickly surprised to find out from close contact that Great Wall Motors' hybrid technology has reached such a mature point. Different from the Japanese hybrid improvement route, the full speed domain of the lemon hybrid DHT operates efficiently, providing a performance and energy-saving experience that is more suitable for Chinese consumers.
But lemon-blended DHT is much more than that. In the past many years, China's hybrid market has been dominated by overseas, especially Japanese brands, from R & D and production to terminal products, and Chinese brands are almost invisible. Today, Great Wall Motor's lemon hybrid DHT has taken the lead in getting rid of this situation and establishing a set of innovative solutions belonging to Chinese brands, thus pushing the entire industry into a new blue ocean of hybridization. With the new progress of Great Wall Motors breaking through the technical barriers of hybridization, China's automobile industry has also moved to the next round of technological change, with the ultimate goal of making up for the shortcomings in the field of hybrid.
In addition, there is a point that hybrid energy saving is not only China's route, but also a global consensus. Under the international development plan of Great Wall Motor's "going global", the technical support of lemon hybrid DHT is indispensable.
"Reserves" below the surface of the water
In the past year, lemon hybrid DHT has gained a lot, in addition to the sales of several new cars, there are affirmations from professional fields: the 1.5T hybrid system won the "Chinese heart" annual top ten engines, and the DHT hybrid gearbox was named "the world's top ten gearboxes".
With the launch of lemon hybrid DHT, the strength accumulated by Great Wall Motors in new energy technology has been successively presented. Around 2018, Great Wall Motors began to develop the hybrid system, during which they won 199 technical patents, 80 core patents, in a long-term monopoly of overseas brands, lemon hybrid DHT became the first Chinese brand to launch a dual-motor hybrid hybrid architecture product, which is not an easy task.
In the eyes of many people, lemon hybrid DHT and new energy route 2.0 coincide in time and direction. Behind the luck is Great Wall Motor's forward-looking layout of new energy technology. Hybrid power is only one of them, and the hot sales of Euler brand models in 2021 and the appearance of high-end brand salons present us with the accumulation and outbreak of Great Wall Motors in the field of pure electricity.
At last year's Guangzhou Auto Show, Great Wall Motors launched a high-end pure electric brand salon, and the first mass-produced car, the Mech Dragon, was a high-performance electric vehicle priced at up to 480,000. Many people are surprised by this, because before this, Great Wall Motors' pure electric products were only the small car Euler in the mainstream household market.
Regarding the mech dragon car, in addition to the labels of 3.7 seconds acceleration and four lidars, we also saw a very important safety highlight: 1037 ° C high temperature does not ignite, does not explode. This thermal runaway safety technology comes from Dayu Battery Technology, which Great Wall Motors released last June.
In recent years, we have seen Great Wall Motors actively build technical barriers in the field of new energy, and Dayu Battery Technology has paid attention to a major pain point of electric vehicles: safety.
Power battery failure, thermal runaway and other issues are the most concerned by consumers, but also the most worried, Great Wall Motor launched the Dayu battery technology borrowed from the Dayu zhi water "change blockage to thin" thinking, put forward heat source partition, two-way exchange, heat flow distribution, directional discharge, high temperature insulation, automatic fire extinguishing, positive voltage oxygen resistance, intelligent cooling and other 8 innovative designs, through advance control, risk diversion to deal with battery safety risks. In a series of rigorous tests, this technology has achieved "any position in the battery pack" and "single or multiple cells" without fire or explosion in the case of triggering thermal runaway.
When consumers buy new energy vehicles, safety is the most basic consideration. Great Wall Motors was the first to carry Dayu battery technology on the high-performance mecha dragon, and will continue to install this technology on all new energy models. At that time, the safety of Great Wall Motors in the field of new energy will rise to another dimension.
The technical height obtained by long-term investment has brought self-confidence and responsibility to Great Wall Motors. Considering the urgent need to improve the safety of new energy vehicles, Great Wall Motors decided to open dayu battery technology patents to industry applications free of charge.
There are actually two layers of significance, Dayu battery technology represents the highest level of power battery safety protection at this stage, once open for use, the safety of the entire new energy field will be rapidly improved; at the same time, a number of technical patents of Dayu battery can also be studied by peers, and even innovated and upgraded, which is of great significance for promoting the industry forward. All this is based on the selfless contribution of Great Wall Motors, behind which is the development pattern and social responsibility of a large enterprise.
Larger "glaciers" beneath the surface of the water have long since formed
Maybe we don't pay much attention to a detail, Great Wall Motors mentioned when releasing the 2025 strategy last year that they want to achieve 80% of new energy vehicles in 2025 and fully achieve carbon neutrality in 2045.
The transformation and electrification of traditional car companies is the trend, but in 2025, the proportion of new energy vehicles will reach 80%, which is not an easy goal to achieve. To this end, Great Wall Motors invested and accumulated energy early, which allowed us to see the rapid popularization of lemon hybrid DHT models in 2021, the Euler brand sitting firmly in the first camp of new energy vehicles, and the birth of high-end electric brand salons.
From the perspective of the entire industry, the new energy route 2.0 affirms the inevitability of the long-term coexistence of hybrid and electric routes, Great Wall Motors holds the hybrid and pure electric product lines, and has core technologies such as lemon hybrid DHT and Dayu battery technology, which is enough to support its multiple brands to respond well to industry changes and complete the double carbon target. However, as a car brand that is ahead of the curve, Great Wall Motors obviously thinks more and does more. Is there any other path to reach the "carbon neutral" destination in 2045 besides hybrid and electric?
Great Wall Motors set its sights on hydrogen and released its hydrogen strategy in March last year. As a Chinese brand that has invested in hydrogen energy research and development for a long time, Great Wall Motors has 21 years of accumulation in this field, and now successfully breaks the core technical barriers in the field of hydrogen energy and obtains fully autonomous product intellectual property rights, which is also the first time in the industry. At present, Great Wall Motor's hydrogen energy technology has opened up the upstream and downstream industrial chains, forming a set of international-level "production-storage-transportation-plus-application" supply chain ecology.
We are in a resource-rich energy country such as wind energy and solar energy, and making full use of them to obtain hydrogen energy will have great promise in the future, but no Chinese car brand has enough technical strength to devote itself to it before. In 2021, while Great Wall Motors released its hydrogen energy strategy, it has begun to apply technology and products, including 100 49-ton hydrogen energy heavy trucks entering the commercial market, and the world's first C-class hydrogen fuel cell SUV will soon be unveiled.
The mass production of hydrogen fuel cell vehicles is a great test of supply chain layout and verification capabilities, and the development and landing of hydrogen energy in the field of commercial vehicles and passenger cars of Great Wall Motors is so rapid, mainly due to a set of "hydrogen capacity system" full-scenario solution - hydrogen lemon technology. In this set of vehicle-level R&D system, covering hydrogen power (HE), stack (HS) and hydrogen storage (HP) three technology platforms, and from the terminal experience, use scenarios and other aspects of consideration, Great Wall Motor's hydrogen lemon technology has reliability, durability, safety, environmental adaptability, high power, high power density characteristics, so that a hydrogen energy vehicle can truly release high efficiency, high performance, long endurance, all-climate driving and all-field application of technical advantages.
There is one piece of information about hydrogen energy strategies that deserves attention. Hydrogen lemon technology, like lemon hybrid DHT, belongs to the core technology route of Great Wall Motors' lemon platform. We can regard the lemon platform as the "technology iceberg" of Great Wall Motors, which involves many aspects such as power system, body safety, and lightweight, and almost covers the needs of technology upgrades of many brands under Great Wall Motors.
In 2021, Great Wall Motors mainly presents us with their various route layouts in the field of new energy, in addition to the original high-efficiency internal combustion engine, Great Wall Motors has completed the technical application of hybrid, pure electric and hydrogen energy. Moreover, when Great Wall Motors develops and designs a variety of power routes under the lemon platform, it takes into account the adaptability of the global market, which is also a manifestation of Great Wall Motors' advanced planning and comprehensive consideration in the technical field.
Asteron summary
Whether it is the 2025 strategy or the 2045 vision, these are The Great Wall Motors' thinking on future competition and the driving force for the development of enterprises, but to truly realize the formation of a technology iceberg, it is not a cold day. We now see that Great Wall Motors has entered the technology harvest period, from a lot of exploration and accumulation in the early stage.
As the head of the Chinese brand, Great Wall Motors has come up with hybrid, pure electricity, and hydrogen energy technologies, which are of course inseparable from talent reserves and a large amount of capital investment, but the human and financial resources are not enough for Great Wall Motors to form today's competitive advantage. Great Wall Motor's new energy products have quickly gained the affirmation of users since their perennial attention and research on user needs, thinking about problems from the perspective of users, solving problems, and finally presenting products that have won the hearts of the people.
Holding technology in hand, having users in mind, basing on the present, and focusing on the future, Great Wall Motors can always do the right thing at the right time. This is true of the lemon hybrid DHT, and even more so for the hydrogen energy strategy. For a long time, we only paid attention to the product diversity of Great Wall Motors in the end market, and rarely paid attention to the technical support behind rapid product updates. Today, standing in the current era of electrification transformation, long-termists are reaping the fruits, and we see the growth and self-confidence of a Chinese brand, and have the strength to go to the global market. With the passage of time, a huge "technology iceberg" gradually surfaced, and the technical image of Great Wall Motors will be clearer.
