Between SAIC and the future, a "nebula" has been set up

The accumulation of SAIC's accumulation, this time came quite violently.

Unlike many car companies who are keen on marketing, SAIC is more like a "technical house" in the automotive circle. Whether it is due to the rigor of the group company, or because it has implemented the engineer's thinking of excellence from top to bottom, so many years. , "Just do not say" has indeed become a more prominent corporate feature of SAIC.

Therefore, when the "seven major technical bases" "seven swords down the Tianshan Mountains" together, the shock brought to the industry can be imagined.

At the shareholders' meeting in May, SAIC announced publicly for the first time that it would focus on new smart electric vehicles to build "seven major technology bases", including three major vehicle technology bases and four key system technology bases ("Nebula" pure Electric exclusive systematic platform, "Mount Everest" mechatronics architecture, "Galaxy" hydrogen energy exclusive architecture, "Blue Core" powertrain system, platform-based "Cube" battery system, "Green Core" electric drive system, "Galaxy" "Full Stack Smart Vehicle Solutions).

From pure electric to hybrid to hydrogen energy, from traditional powertrain system to battery system to electric drive system and full-stack intelligent solutions, in the current hottest and most forward-looking technology field, SAIC's attitude this time It is very clear that not only all of them are required, but also to let the industry see what is really leading technology.

On June 24, SAIC Innovation Research and Development Institute conducted a more detailed interpretation of the "seven major technical bases". We can first pass a few sets of data to feel SAIC's determination to subvert the industry.SAIC Lanxin Powertrain has created the top ten engines and top ten gearboxes, and the thermal efficiency of the next-generation engine will exceed 47%; the cube battery module can achieve a high temperature of 50 degrees, and two battery cells fail to puncture without thermal runaway (previously in the industry. The same type of test temperature is generally 10-25 degrees, and a single cell fails); the green core drive system has a power bandwidth of 150KW to 600KW, which improves the electric drive efficiency to a new height; in addition, it has caused heated discussions in the industry There is also the Nebula platform. Through this pure electric exclusive systematic platform, SAIC's electrification road has officially entered a new stage, and it is also a higher stage that other brands have not yet explored.

As soon as the shot is launched, it is the first in the industry

"SAIC Nebula" is the first pure electric exclusive systematic platform in China's auto industry.

Under the background of the 'dual carbon' strategy, the development of the domesticnew energy vehicleindustry has ushered in a major opportunity, and the transition to electrification has become the main theme in the domestic automobile market. Before that, many brands have officially announced their own pure electric exclusive platform.Many people here may have a doubt, why is the SAIC Nebula platform the first pure electric exclusive systematic platform in the Chinese auto industry?Faced with this question, Lu Yong, executive vice president of SAIC Innovation Research and Development Institute, gave a standard answer: "The biggest difference from the pure electric exclusive platform of other brands, SAIC Nebula is a systematic exclusive pure electric platform."

How to understand this "systematization"?In simple terms, a platform can be called a pure electric platform only for one or two electric vehicles, but this platform must not constitute a systematic platform.This is also the main reason why many car companies are reluctant to build a pure electric platform. Due to the limitations of insufficient platform power bandwidth and insufficient gradient, after developing one or two cars on this platform, you will find that you cannot continue. To develop the next car, it is necessary to develop another platform. Such a model is a huge burden on the R&D cost and R&D progress of the enterprise.

How to solve the common problems in this industry?SAIC's answer is to be a pure electric exclusive system platform.Then the question comes again. Since this common problem can be solved, why is SAIC the first car company to do so?The reason is actually very simple. To do this pure electric exclusive systematic platform, not only need the enterprise to have a strong technical background, but also need to make forward-looking prediction and layout for future market demand.In other words, the pure electric exclusive systematic platform tests the comprehensive strength of the enterprise in the field of electrification. It needs to invest a lot of capital and human resources. There are not many car companies willing and able to do so.

For SAIC, which started to develop the pure electric market 10 years ago, the profound technical foundation accumulated in more than ten years of unremitting efforts is the major prerequisite for the development of the exclusive systematic platform of Nebula pure electric, and the related technical talents have been cultivated over the years. , which is the foundation for the development of the Nebulas platform.

The SAIC Nebula pure electric exclusive system platform has future-oriented and highly flexible technical scalability. It has an ultra-wide energy matrix of 44-150kWh and an ultra-wide power range of 150-600kW, covering compact cars, medium cars, medium and large cars,luxury cars It can develop various types ofvehicleproducts such as sedans, sports cars, SUVs, MPVs, etc., and is also compatible with high-voltage casting, solid-state batteries, wire-controlled chassis, full-stack electrical architecture, unmanned driving, etc. The cutting-edge technology of software and hardware reflects the highest level of "Made in China" in the automotive industry.

SAIC's "Nebula" and the future

In the official definition, "SAIC Nebula" is the carrier of SAIC's "new four modernizations" strategy and "cloud-pipe-end" technology. The gradient super platform will become the exclusive main platform for SAIC Group to fully realize electrification.

At present, SAIC already owns the high-end brand Zhiji and the mid-to-high-end brand Feifan. Meanwhile, Roewe and MG are also fully promotingnew energy.To empower the four major brands at the same time, what does SAIC Nebula rely on to achieve?

The first is to rely on the accumulation of the past ten years.SAIC is the first company in China to develop platform-based architecture and pure electric vehicles.In 2010, SAIC started the development of the benchmarking MQB architecture. In 2015, when SAIC started the development of the second-generation architecture, it has begun to simultaneously transform to electric drive. Both Roewe and MG have developed a variety of representative models. sexual products.In terms of pure electric vehicles, SAIC launched the first pure electric vehicle in China in 2011, and the electric vehicle Marvel X, which was born in 2018, has set a double benchmark for domestic electric vehicle performance and energy consumption.As Kang Huaping, Vice President of SAIC Innovation Research and Development Institute, said: "Through the development of two generations of architecture and two generations of pure electric vehicles, SAIC has accumulated a lot of experience and data, and has also gained a deeper understanding and understanding of the pure electric exclusive platform. Knowing.” Kang Huaping also pointed out that SAIC has actually started the development of the Nebula pure electric exclusive system platform while building the Marvel X car.

The second is the future-oriented layout.The name "Nebula" itself is very futuristic. In the official introduction, the car continuously iterates itself through the calculation of big data to meet the needs of thousands of users, which is the origin of the name of Nebula.Therefore, Nebula is not only a pure electric platform, but also a platform for SAIC's "software-defined car, data-determined experience".

To sum up, the series of models of the Nebula platform will have the following main features, which will solve the core pain points of electric vehicle users.

bigger space.By lengthening the wheelbase, compressing the front and rear suspension and air conditioning and other technologies, more space will be left for the driver and passengers.Under the premise of the same vehicle length, the wheelbase of the Nebula platform product can be more than 200mm larger than that of the fuel vehicle platform product.

Super long battery life.The ultra-long wheelbase can be equipped with a battery pack with a length of 2023mm, which can achieve an ultra-long cruising range of 1,000 kilometers (according to SAIC's plan, it will achieve an ultra-long cruising range of 1,000 kilometers in 2023).

Super fast replenishment.The 800V fast charge of the Nebula platform can achieve 200 kilometers of battery life in 5 minutes (charge to 80% in 15 minutes); the 400V fast charge can achieve 100 kilometers of battery life in 5 minutes (charge to 80% in 30 minutes).In addition, SAIC Nebula will also provide the function of filling up the battery in 2-3 minutes - quick battery replacement.

Super safe.The security of the Nebula platform covers four aspects, electrical security, structural security, network data security and intelligent active security.In a word, Nebulas is a platform developed on the basis of the world's latest five-star and IIHS index excellence, and every product built based on this platform has the world's highest standard of five-star safety.

Super performance.The overall mode of the vehicle body of the Nebula platform is greater than 50HZ, and the overall torsional stiffness is greater than 40000Nm/Deg.Just looking at the data may have no concept. Let’s make an analogy. The torsional stiffness greater than 40,000Nm/Deg used to only appear on million-dollar luxury cars.

A high degree of intelligence will also be a major feature of the Nebulas platform.The Nebulas platform loaded with the "Galaxy full-stack systematic solution" supports L3+ high-level intelligent driving capabilities, and has "cloud, management, and end" 3-in-one, 3-screen smooth connection, truly realizing thousands of people and thousands of faces.

It can be said that the Nebula platform will be the core weapon for SAIC Motor to sprint in the low-carbon and intelligent direction in the future. While improving user experience, it will also implement SAIC's corporate vision of leading green technology and chasing dreams and wonderful travel.The Nebula platform not only enables SAIC Group to lead the industry in the process of embracing electrification, but more importantly, this pure electric exclusive systematic platform that will re-establish a new industry standard also represents the highest level of its own brand, which can be used in larger On the stage, it has won the industry voice for Chinese car companies.
