Climate change is a common challenge facing human society. In 2015, nearly 200 countries and regions around the world reached the Paris Agreement to address climate change.
As of September 2021, 121 countries around the world have proposed to achieve carbon neutrality by the middle of the 21st century, while mainland China has proposed the development goal of "striving to peak carbon dioxide emissions by 2030 and striving to achieve carbon neutrality by 2060".
Although it seems that there are still nearly 40 years to go, China, as the world's largest carbon emitter, is imminent to promote "carbon neutrality" as soon as possible. Among them, the road transportation sector has become one of the important sources of carbon emissions in China, and the total number and increment of motor vehicle ownership in China are also the first in the world.
Therefore, whether China's automotive industry can complete the "carbon reduction" task on schedule or even ahead of schedule plays a crucial role in the realization of the strategy of the whole country.
On March 18, the "2022 International Summit Forum on Vehicle Powertrains" guided by the Passenger Vehicle Powertrain Professional Committee of the China Internal Combustion Engine Industry Association was held in the form of digital connection cloud live broadcast. At this forum, the guests unanimously agreed that whether China's automotive industry can complete the "carbon reduction" task on schedule or even ahead of schedule plays a vital role in the realization of the strategy of the whole country, and hybrid is an important path to "break the game and double carbon".
(1) Why hybrid?
From the current trend, electrification is still the mainstream in the future, but it is not fully mature at present. Especially from the perspective of the general environment, the rise in battery raw materials that began last year has interrupted the downward trend of new energy costs that has lasted for many years, making the power electrification path begin to trend towards the direction of "sustainable cost reduction".
In this case, hybridization becomes the optimal solution for the moment.
From the data point of view, the cost of hybrid is half or less of the cost of pure electric, and it has the advantage of long endurance, there is no mileage anxiety, and it is the solution that best meets the dual needs of the market and the environment.
In addition, due to the severe international situation this year, the price of nickel metal and other materials has been exacerbated, and the cost of lithium batteries has further increased. The sharp rise in oil prices and the increased pressure on the cost of fuel vehicles have also made the consumer market more enthusiastic about fuel-saving models. Hybrids are in the best part of development.
"Hybrid is not only a fuel-saving machine, but also a comprehensive pursuit of economy, power, comfort, convenience and intelligence." In the view of Lin Xiaozhe, vice president of Geely Power Research Institute, oil-electric hybrid is an excellent solution for environmental friendliness in the process of industry transformation, which can not only drive the upgrading and emission reduction of fuel vehicles that account for the majority of market demand, but also help promote the development of electric technology.
In fact, in 2021, mainstream independent brands have laid out the DHT-PHEV hybrid technology route. Among them, the most representative technology is the LeiShenZhi Qing Hi · X Hybrid System.
(2) Far beyond "Two Fields", Ray's Mind Qing Hi · What are the advantages of X?
On October 31 last year, Geely Automobile officially released the global power technology brand - Leishen Power, and the world-class modular intelligent hybrid platform - Leishen Zhiqing Hi · X。
Among them, "X" means that it can support different hybrid forms such as HEV oil-electric hybrid, PHEV plug-in hybrid, REEV extended range hybrid, and support coverage from A0 class models to C class models.
In terms of efficient engines, Ray's Mind Power Hi · X offers two hybrid engines, the DH15 and DHE20, and the gearbox is available in DHT (1st gear transmission) / DHT Pro (three-speed transmission). It is worth noting that the first mass-produced 3-speed hybrid electric drive transmission DHT Pro, the hybrid special engine DH15 thermal efficiency of up to 43.32%, fuel saving rate of more than 40%, is a FOTA upgradeable hybrid system.
The choice of battery pack is a HEV battery pack with 1.8kWh, and a PHEV battery pack that supports 200 km of pure electric endurance, which supports full coverage of A0-C class models, and covers a variety of hybrid technologies such as HEV, PHEV, and REEV. Currently, Ray's Mind Ishi · X has comprehensively surpassed the Japanese "Ryota" in key technologies.
In the next three years, it will provide a variety of power combinations including strong hybrid, long-endurance plug-in hybrid and extended range hybrid, which will be installed on more than 20 models of Geely, Lynk & Co and other brands. It can be said that Thor Power and Thor's Intelligence Hi · X brings Geely into a new era of electrification of Power 4.0 technology. In addition, Geely has also formed a global R&D system layout in terms of pure electricity ecology, power exchange and new fuels.
(3) Kung Fu shooting
From Ray's Mind Tohi X and other technologies, we can see that Chinese companies represented by Geely are taking the "double carbon" as an opportunity to make a breakthrough in intelligence and electrification to achieve accelerated overtaking on the new track.
In the exploration of energy diversification, brands such as Geely and Hongqi have also gradually solved the technical problems in the application of methanol and hydrogen fuels in internal combustion engines. These attempts are also accelerating the transformation of the mainland from traditional energy to new energy power, and boosting the continuous upward movement of Chinese brands.
