In the peak era of internal combustion engines, Nissan VQ series engines have won the title of "Ward's Top Ten Engines" for 14 consecutive years, and are known as a generation of god engines.
With the replacement of technology, the era of internal combustion engines has come to an end, and new energy has risenPerhaps Thor Power has this responsibility.
From December 7th to 9th, the 2023 World New Energy Vehicle Conference was held in Haikou. At the conference, Leishen Power's high-performance inverter hybrid platform won the 2023 "Global New Energy Vehicle Innovation Technology" award. There may be friends who are not clear about the gold content of this award, let's briefly popularize science.
Since 2019, the World New Energy Vehicle Conference has organized the global selection of cutting-edge and innovative technologies for new energy vehicles for four consecutive years, and has selected a total of 33 innovative technologies and 28 cutting-edge technologies, which have received great attention from all walks of life at home and abroad. The results of the scientific and technological selection have played an important role in guiding the direction of new energy vehicle technology research and product development, promoted the gathering of innovative elements and industrial resources, and has become the vane of global new energy vehicle innovation and development.
Wan Gang, Chairman of the China Association for Science and Technology and Chairman of the World New Energy Vehicle Conference, presented the award to Wang Ruiping, Senior Vice President of Geely Automobile Group and President of the Power Research Institute.
In addition to the 2023 "Global New Energy Vehicle Innovation Technology" award, Leishen Power's new-generation Leishen electric hybrid engine BHE15 PLUS and Leishen electric hybrid 8848 hybrid system were also successfully selected as the "China Heart" 2023 Top Ten Engines and Hybrid Systems. Leishen Power's "Key Technology and Industrialization of New Generation Hybrid Power System" project won the first prize of the "Science and Technology Award of the Society of Automotive Engineers of China" Science and Technology Progress Award. So far, Leishen Power has won the first prize of scientific and technological progress twice, and has been awarded the top ten engines and hybrid systems of the "China Heart" for ten consecutive years.
A set of self-developed domestic hybrid powertrain can defeat a number of joint venture competitors and repeatedly win the highest awards in the field of domestic automotive power systemsAnd what does China's hybrid technology bring to Chinese automobiles?
Top-notch technical solutions must be both and beyond
Time flies, and the large-scale marketization of hybrid vehicles has gone through more than 20 years. In 2003, the second-generation Toyota Prius was imported into China, and then produced by FAW Toyota in 2005, allowing Chinese consumers to experience a novel concept of "not only horses running, but also horses eating less grass".
For the next decade, the hybrid market was largely dominated by the Japanese. Toyota, Honda, Nissan and other Japanese brands continue to iterate on hybrid technology, and they have a common advantage, that is, fuel efficiency. The concept of "Japanese hybrid fuel saving" was deeply rooted at that time.
However, the Japanese hybrid's blind pursuit of low fuel consumption has led to poor power performance, even if it is equipped with a 2. like the Lexus ES300HThe 5L large-displacement engine and THS hybrid technology model can accelerate to 100 kilometers per hour in nearly 10 seconds. Talking about being full of motivation is far from qualified.
On the other side of the world, Europe, a few years after the Japanese launched hybrid technology, the European system has also embarked on the road of hybridization. But instead of being fuel-efficient, they're aiming for another KPI – power. When the internal combustion engine of fuel vehicles is started, it is often due to the slow rise of the speed that leads to insufficient power, and there is a low torque weakness, and the motor is explosive when the motor is energized, which has become a good medicine to solve this problem.
Add a motor between the engine and the gearbox, and when you step on the accelerator, the engine is still half-asleep and half-awake, and the motor has dragged the vehicle dozens of meters away. But this does not have much benefit to fuel consumption, and the overly complex structure also greatly reduces the stability of the vehicle, and even the strange phenomenon that the Mercedes-Benz S400 Hybird is cheaper than the S300 in the second-hand car market.
Is there a hybrid system that takes into account the fuel consumption of the Japanese and the power of the European system?
Yes, Thor Power is!
The product is the award-winning high-performance inverter hybrid platform of Leishen Power, and we start with the representative Leishen electric hybrid 8848.
The core of the LEISHEN electric hybrid 8848 is a three-speed inverter electric drive DHT PRO. Compared with the popular single-speed hybrid transmission, its biggest feature is that it has three gears, and the advantage of multiple gears is also very obvious. The vehicle can find the corresponding gear matching under various power needs to achieve excellent performance of "all-weather and all-road conditions".
In addition, the three-speed inverter electric drive DHT Pro also has a dual-clutch and dual-braking design between the three gears, which can bring 20 different working modes through permutation and combination.
In actual driving, real-time analysis can be carried out according to the dynamic data provided by navigation data, weather information, real-time road conditions, driving Xi and even vehicle adas, etc., and the most cost-effective gear combination can be selected to ensure that the power system achieves fuel consumption and power balance.
Don't look at the multi-function of this three-speed inverter electric drive DHT Pro, but the size is very small. The dual-planetary multi-gear coaxial electromechanical coupling technology pioneered by Leishen Power realizes a variety of working modes of "engine 3 gears + motor 3 gears" through clutch combination switching. Compared with the same type of gearbox, it has three technical highlights: the smallest size, the largest output torque, and the most working mode, and always allows the engine to run in the high-efficiency range.
Let's look at the Raytheon electric hybrid engine BHE15 Plus. With a maximum output of 120 kW and a maximum torque of 252 Nm, it provides stable and continuous high-efficiency power output. As the power source of the Thor electric hybrid 8848, it has 44Ultra-high thermal efficiency of 26%. Toyota, which has decades of experience in the development of internal combustion engines, has only a little more than 40% thermal efficiency in its hybrid models. The extremely high performance of the BHE15 Plus has also earned it the title of "Energy Efficiency Star" awarded by CAERI Huacheng Certification.
The BHE15 PLUS+ three-speed inverter electric drive DHT Pro electric hybrid engine can achieve simultaneous output of three power sources in the case of urgent power needs such as rapid acceleration and high-speed overtaking. Taking Geely Galaxy L7 as an example, the engine + P1 motor + P2 motor = 120KW + 60KW + 107KW, so that this system has a total drive power of 287KW, which is 27% higher than the power before the upgradeAt the same time, the WLTC fuel consumption is only 5The 23L 100km truly achieves the perfect balance between European power and Japanese energy saving.
Ten years of sharpening a sword, put in the burning
In the 21st century, talent is the most expensive!”
This line of Ge You in the movie "No Thieves in the World" unexpectedly hit the core of the development of China's automobile industry in the next 20 years. The most intuitive embodiment of talent is technological innovation.
Looking through the historical materials, there is a surprising discovery: gasoline-electric hybrid technology has a history of 100 years, as early as the Guangxu period of the Qing Dynasty, the world's first gasoline-electric hybrid car has been launched. However, at that time, this technology was not introduced to save fuel, but was limited by the low level of engine development and manufacturing, and the traditional internal combustion engine was not powerful enough and needed to rely on the electric motor to help.
It is Toyota that is actually mass-producing and promoting the gasoline-electric hybrid technology. In 1994, Toyota convened 10 technical backbones around 30 years old from various fields such as body, chassis, and engine to form the G21 project team.
The research project of domestic automobile manufacturers on this technology is also earlier than we imagined.
Speaking of which, we have to mention the cradle of Leishen Power - Geely Power Research Institute, although it was established in 2013, but as early as the year has a professional team began to develop hybrid technology. After nearly 20 years of continuous exploration, finally in 2018, the first hybrid engine was mass-produced, GHS 1The 0 hybrid system also officially opened the Geely hybrid era. Awarded the title of "China Heart's Top 10 Engines in 2019", this set of dynamic motorsport was installed in the Lynk & Co 01 HEV model and exported to Europe for the first time, with a cumulative export volume of more than 40,000 units.
Geely Power Research Institute has also become the power R&D base of Geely Holding, with the world's leading R&D capabilities in engines, transmissions, and electric drives in addition to hybrid systems.
Up to now, there are nearly 2,000 R&D personnel. Among them, there are nearly 500 international talents, experts and doctors. The output of engines and gearboxes has exceeded 12.5 million units, and the output of more than 3.5 million gearboxes has been developed, and with Geely, Lynk & Co, Proton and many other brand products, it has been sold well in more than 60 countries and regions around the world such as Sweden, the United Kingdom, and Malaysia.
Throughout the ten-year development process of Geely Power Research Institute, it can be summarized in four eras:
1.0 era, independent research and development of naturally aspirated engines and automatic transmissions, to fill the domestic gap;
2.In the 0 era, the company independently developed a direct-injection supercharged engine to complete the transformation of the power system from existing to strong
3.0 times, launched 15TD+7DCT high-performance power platform, and realize the world's first comprehensive technical route covering multiple powers with a single platform, and achieve the grand goal of going global
4.In the 0 era, Leishen Power was released, fully moving towards a new era of electrification of power technology, and began to realize the great dream of China's power world.
Behind the R&D results, there is real gold**. In the 10 years since its establishment, Geely Power Research Institute has built a series of test centers with world-class standards. For example, the new energy power test center is currently the largest investment scale, the most advanced equipment, the most complete functions of the same kind of test center. It is also the industry's first full-coverage, full-simulation, full-development "virtual + physical" verification test center. Support the power verification test work of luxury, high-performance, supercar and other models.
Looking at the powertrain extreme climate environment simulation cabin, it is the first laboratory in China to cover complex environmental factors such as temperature and humidity, light, and altitude. The test range covers extreme climate conditions such as -40 to 60 ambient temperature, 5-5000m altitude pressure, 10%-90%RH ambient humidity, 300-1200W sunlight illumination, etc.
The advanced Thor power did not fall from the sky, but the fruit of Geely Automobile Group's investment of manpower, material and financial resources and long-term transformation. What's more, instead of giving high premiums to excellent products, they dilute R&D costs through mass production of many brands for the benefit of all consumers.
The market is the litmus test of technology
Whether the product is good or not, the sales volume has the final say!
It seems like a simple sentence, but many car brands just can't figure it out. Taking Mazda as an example, it has invested heavily in the research and development of gasoline engine compression ignition technology, which has attracted cheers from the people. However, after being put on the market, sales were dismal, and this kind of self-motivated research and development that disregarded the market was equivalent to suicide in the commercial society.
On the other hand, the Raytheon series products have been widely used in HEV PHEV hybrid models of several brands of Geely Automobile Group, with a total of more than 14 models launched, covering compact sedans and medium and large SUVs.
Taking the Galaxy L7, the first model of Geely Galaxy launched in June this year, as an example, it is equipped with the Thor electric hybrid 8848 system, and its sales exceeded 10,000 units in the second month of its launch, setting a new speed record for China's hybrid SUV "monthly sales exceeding 10,000". With the successive launch of Galaxy L6, Lynk & Co 08 and other models, the popularity of Leishen Power in China continues to increase.
Since its birth, Leishen Power series products have sold nearly 830,000 sets, and it is expected to save 1500 million liters.
As a proof of technical strength, Leishen Power will also realize technology going overseas through cooperation.
In July this year, Geely Holding Group and Geely Automobile Holdings*** and Renault Group announced the establishment of a joint powertrain technology company. The new company will develop and manufacture world-leading hybrid and gasoline powertrains on a global scale. The annual production capacity will exceed 5 million sets, which can cover 80% of the global market demand for fuel-powered and hybrid vehicles, and meet the needs of international brands such as Volvo and Renault for hybrid systems.
The rivers and lakes that belong to the Japanese hybrid have long been old, and now the world's hybrid looks at China.
The emergence of the new generation of LEISHEN electric hybrid system, with the "double degree" advantage of performance and fuel consumption, has helped China's hybrid technology to win a leading position in the international market.
Conclusion
Do you still remember the guide price of the domestically produced Toyota Prius when it was just launched in 2005?
25.980,000 yuan!
With the rise of China's own brand hybrid systems such as Leishen Power, the first hybrid has been rewritten to benefit countless consumers.
The best of hybrid technology has pulled down the altar, and it has also pulled Toyota, Honda, Nissan and other joint venture hybrid brands into the quality war. The essence of quality warfare is technical strength warfare.
Therefore, even Japanese hybrid car owners should be grateful to the domestic hybrid technology represented by Raytheon Power, which is the one who pulls down the joint venture hybrid. This is the greatest return to ordinary consumers.
