Interpretation in the industry: breaking the new scheme of double carbon, hybrid technology has become a new choice for independent brands

Easy Car News On March 18, the "2022 International Summit Forum on Automotive Powertrain" guided by the Professional Committee of Passenger Car Powertrain of China Internal Combustion Engine Industry Association (hereinafter referred to as SCP) was successfully held in the form of digital internet cloud live broadcast.

Guests from industry associations, scientific research institutions, well-known universities, automobile manufacturers, spare parts and fuel suppliers conducted in-depth discussions on topics such as energy structure reform, industry development trend, hybrid technology and China brand cohesion around the theme of "Breaking Double Carbon".

It is an arduous task for the automobile industry to achieve "carbon neutrality" and "carbon emission reduction" in 2060.

In 2020, China officially put forward the development goal of "carbon dioxide emissions should reach the peak by 2030 and strive to achieve carbon neutrality by 2060". At present, China is the largest carbon emitter in the world, and road traffic is one of the important carbon emission sources in China. China ranks first in the world in terms of vehicle ownership and increment. Therefore, whether China's automobile industry can complete the task of "carbon reduction" as scheduled or even ahead of schedule plays a vital role in the realization of the national strategy.

Wang Ruiping, Senior Vice President of Geely Automobile Group, Chairman of SCP and Chairman of APS, believes that there is still a lot of room for the development of China brand in terms of volume, and the window opportunity of electrification transformation of automobile industry is fleeting, so enterprises must seize the opportunity to follow up the changes. The realization of the goal of "double carbon" in the automobile industry requires the joint efforts of the main engine factory and the whole industrial chain of road traffic.

The theme of this forum is "Breaking the Double Carbon". The main purpose of this forum is to discuss the diversified and hybrid technical route of vehicle power system under the transformation and upgrading of China automobile industry during the implementation of the "Double Carbon" goal.

The improvement of the weight of hybrid technology has become a new direction for the development of car companies.

Although authoritative organizations in the industry have different assessments on the contribution of hybrid electric vehicles and electric vehicles in reducing carbon emissions, the view that hybrid kinetic energy can significantly reduce carbon emissions of fuel vehicles is the same. At the same time, the travel experience of hybrid electric vehicles is more in line with the actual car demand of China consumers.

In addition, from the macro environment, the rapid rise of battery raw materials since last year has interrupted the downward trend of new energy costs that has lasted for many years, triggering the power electrification scheme may change the path and tend to the direction of "sustainable cost reduction". At the same time, the conflict between Russia and Ukraine this year led to a sharp rise in the price of nickel metal, which made the cost of lithium batteries worse. Coincidentally, with the long-term conflict between Russia and Ukraine, oil prices have also risen one after another, and the increasing pressure of oil cost has stimulated consumers to choose new energy vehicles, which has increased the weight of hybrid technology in the layout of automobile enterprises.

The cost of hybrid power is half of that of electric vehicle or less than 65,438+0/4, which has the dual advantages of new energy, fuel economy and convenient energy supplement for fuel vehicles. Hybrid power is not only a fuel-efficient machine, but also an all-round pursuit of economy, power, comfort, convenience and intelligence.

In general, the hybrid technology that was once marginalized by various car companies has returned to the right track. At present, the domestic BYD DM-i hybrid model is extremely hot, and several products under the Great Wall lemon DHT hybrid platform also have good attention. The brand-new Raytheon hybrid sedan Xingyue L built by Geely will also be listed soon. In addition, hybrid technologies such as Changan i-DD and Chery Kunpeng DHT are in full swing, which indicates that hybrid technology has returned to the embrace of the industry.

Who can break the Japanese monopoly under the new hybrid circuit?

For a long time, when it comes to hybrid technology, many people think of the hybrid technology of two fields in Japan for the first time. Whether it is Toyota THS power shunt technology route or Honda i-MMD power series-parallel technology route, it basically represents the mainstream form of hybrid technology. So how can independent car companies achieve transcendence?

On June 3rd, last year, KLOC-0, Geely Automobile officially released the global power technology brands Raytheon Power and the world-class modular intelligent hybrid platform Hi X. It can be said that it has completely surpassed Japan's "two fields" in key technologies and set a new benchmark for global mixing.

Its first mass-produced 3-speed hybrid electric drive gearbox DHT Pro is by far the most compact hybrid gearbox in the world. Through the third speed ratio, DHT Pro has a maximum output torque of 4920N·m and a torsional mass ratio of 41N m/kg, which is the highest in the world! P 1 generator has no inductance switching, which brings silky smoothness; P2 drive motor+three-gear combination, power is on call. Hi X can enter parallel mode when the vehicle speed is above 20km/h, and realize the ejection start, which is much lower than the parallel speed of Japanese cars at least 70km, and the system efficiency is improved by 20%. Accelerate at 80- 120km/h, release 60% of reserve power, and quickly achieve high-speed overtaking.

Figure: DHE 15, the second hybrid engine of DHT Pro 2, is the world's first mass-produced supercharged direct injection hybrid engine. It adopts four advanced technologies: high-pressure direct injection, supercharged intercooling, Miller cycle and low-pressure EGR. The thermal efficiency is as high as 43.32%, which is better than the highest level of hybrid power in Japan (465,438+0%), and its maximum torque reaches 225N.m, and the torque increase exceeds that of Japanese competitors (765,440). The displacement of 1.5L and the performance of 2.5L bring more than 40% fuel saving efficiency.

Finally, the hybrid system that FOTA can upgrade is also the only one in the industry. There are as many as 20 intelligent working modes, which are infinitely iterative and often used.

In addition, Ray Shen Qing Hi X also includes a 1.5TD/2.0TD hybrid engine and a DHT/DHT Pro hybrid gearbox, which supports the full coverage of A0-C models and covers a variety of hybrid technologies such as HEV, PHEV and REEV, and is highly scalable.

It is understood that Lei Shen Qing Hi X will be carried on the "China Star" for the first time, and the first model, Xingyue L Raytheon Hi X hybrid version, will also be listed soon. In the next three years, it will provide a variety of power combinations including strong hybrid, long-life plug-in hybrid and extended-range hybrid, and carry them on more than 20 models of Geely, Lectra and other brands.

In addition, Geely has also formed a global R&D system layout in pure electricity ecology, power exchange field and new fuels. ?

Editor's comment: In recent years, China brand has also shown an overall upward trend in the field of power system research and development. After going through the process of running together, it even reached a local leading trend. Many car companies have been at the forefront of the world. In the field of hybrid special engines, the thermal efficiency of power brands such as Geely and BYD has exceeded 465,438+0%; In the field of new energy, brands such as Geely and Hongqi have gradually overcome the technical problems in the application of methanol and hydrogen fuel in internal combustion engines. All these show the world leading position of domestic engine research and development level, and sweep away the backward traditional technology and people's impression. From catching up to following, China brand is speeding up overtaking on the new track. Taking the opportunity of "double carbon" and the breakthrough of intelligence and electrification, I believe that the goal of "double carbon" in automobile industry will be realized faster.
