Recently, SAIC Group held a "Smart Coffee Gathering" technology sharing event, showcasing the cutting-edge new energy technologies gathered by its brands in recent years, including the progress and planning of vehicle platform architecture, solid-state batteries, 800V electric drive, intelligent driving, intelligent cabin, and other aspects. The specific landing and concentrated appearance of future automotive forms fully demonstrate SAIC Group's core competitiveness in the new electric intelligent track. These "technological goods" allow users to truly perceive the accumulated and explosive technological strength of SAIC Group in recent years.

Nebula platform shines brightly

The latest pure electric exclusive platform of SAIC Group, Xingyun Platform, is the cornerstone of the construction of the entire new energy track. Zu Sijie, Vice President and Chief Engineer of SAIC Motor Corporation and President of SAIC Innovation Research and Development Institute, stated at a communication meeting that the platform abbreviated as MSP is not only a scalable modular platform independently developed by SAIC based on the exclusive features of pure electric vehicles, but also a gradient super platform.

SAIC Group has a total of 7 technology bases, including 3 vehicle technology bases: SAIC Xingyun Pure Electric Exclusive Systemization Platform, SAIC Zhufeng Oil Electric Integrated Vehicle Architecture, and SAIC Xinghe Electric Hydrogen Integrated Vehicle Architecture, as well as 4 key system bases for intelligent connected vehicles, including Blue Core Powertrain System, Platformized Rubik's Cube Battery System, Green Core Electric Drive System, and Galaxy Full Stack Intelligent Vehicle Solution.

As SAIC Group's first series of systematic platforms exclusively for pure electric vehicles, SAIC Nebula Platform shoulders the heavy responsibility of SAIC's independent electric vehicle research and development base. Its biggest feature is that it has iteration and each system has corresponding gradients. It is reported that on this platform, compact models with a total length of over 4 meters can be developed, as well as high-end cars with a total length of over 5 meters. At the same time, sports cars, sedans, SUVs, and MPVs can also be developed. With the support of "Rubik's Cube" battery technology, the platform can match more than 10 gradient power batteries ranging from 44kWh to 150kWh; Not only that, platform models can also choose multiple energy replenishment methods such as charging or swapping. For today's most core feature of intelligent electric vehicles - upgradability, born on the "Nebula platform", cars can be loaded with SAIC's "Central Computing+Regional Control" full stack 3.0 intelligent vehicle solution, which has been iterated to the third generation, allowing vehicles to have strong self-learning, self evolution, and self growth capabilities, achieving constant use and innovation.

In the past year, SAIC Group has integrated the SAIC Nebula systematic platform from development to mass production, and used it on new energy vehicle models of various brands under SAIC Group, which reflects the biggest highlight of the Nebula platform: gradient, scalability, and iterative upgrading. Born on the SAIC Nebula platform, Zhiji is positioned as a high-end luxury brand. Its features on the L7 and LS7 include a 106 ° wide field of view, a large 5-seater, zero power seats, and a full range of AI cabins; Focusing on the ultimate and extraordinary comfort, the F7 pays special attention to the need for comfort during research and development. It has 8 cabins that conform to the Chinese human body model, providing anti dizziness and 3D effects for the entire vehicle; The MG, which has achieved remarkable results overseas, has high requirements for performance. The Cyberster, which recently debuted at the Goodwood Speed Festival, pursues speed and driving experience. It is expected to sell 150000 MG4 vehicles in Europe this year, with a high safety factor and a zero to 100 km/h acceleration of up to 3 seconds for the four-wheel drive version; In addition, Roewe will also launch the D7 model within this year. In the future, the four major brands will adjust the specific characteristics of their models based on their positioning on the platform.

Solid state batteries create sales of 100000 units

In SAIC Group's view, batteries limit the industrial advantage of electric vehicles that truly form a completely overwhelming advantage. Batteries not only affect the weight of the entire vehicle, but also affect the energy consumption of electric vehicles. What SAIC Group needs to do is to improve the energy density of the battery itself and the energy efficiency of the entire vehicle. To improve the driving experience of electric vehicles, battery and electric drive technology are the core. Every one percentage point reduction in energy consumption and every one percentage point increase in driving efficiency are both manifestations of the deep investment of car companies in technology research and development, and they will also provide a clearly differentiated user experience on the product side.

The most relevant aspect to improving energy efficiency is the battery. At Zhikahui, SAIC Group showcased a solid-state battery jointly developed by SAIC Innovation Research and Development Institute and Qingtao Energy, with a single energy density of 368Wh/kg and a maximum test vehicle range of 1083 kilometers. More importantly, solid-state batteries can effectively solve the contradiction between energy density and safety. It is reported that the solid-state battery can achieve safety performance of L0 level for the entire package in the most rigorous single cell puncture test, ensuring that the entire package will never catch fire or explode after the thermal runaway of a single cell. This solid-state battery also has a cost advantage. "By increasing the range by 10%, the cost of solid-state batteries can be reduced by 10% to 30% compared to traditional lithium iron phosphate batteries," said Lu Yong, Executive Vice President of SAIC Innovation Research and Development Institute.

The 800V silicon carbide electric drive system will also be launched in 2024. Nowadays, the 800V platform is mainly used in battery pack systems, which can significantly improve charging efficiency. However, there are not many car companies that can simultaneously launch the 800V electric drive system. At present, SAIC Group's 800V Sic electric drive system has a smaller internal resistance and higher conversion efficiency due to the addition of silicon carbide, which can improve the overall efficiency of the vehicle by about 3% compared to the current mainstream electric drive system. In terms of structure, this electric drive system uses a combination of flat wire winding motor, oil cooling, four planetary differential, and Boost boost charging module, which can achieve a maximum power of 400kW and peak torque of 500N · m, making it easy for electric vehicles to accelerate from 0 to 100 km/h in less than 3 seconds.

Compared with the current 400V electric drive system, the 800V electric drive system has a higher conversion efficiency, while also considering low energy consumption, which improves the actual range of the product. It is reported that the first Zhiji model equipped with solid-state batteries will be launched in 2024. After iteration, SAIC will also achieve the application of solid-state batteries in entry-level products by 2025, and achieve a sales scale of 100000 vehicles in models such as Zhiji, Feifan, Roewe, and MG.

Intelligent brain fusion across all domains

Among the many technological communication concepts shared by Zhikahui, the author believes that the most important link should be the Zero Beam Galaxy Full Stack 3.0 solution, known as the "Wisdom Brain".

This solution is the third-generation intelligent vehicle full stack technology solution brought by Zero Beam Technology under SAIC Group. Facing 2025, Zero Beam Technology will officially release the Zero Beam Galaxy Full Stack 3.0 solution, adopting a strategy of "central computing+regional control". According to Li Jun, Vice President of SAIC Innovation Research and Development Institute and CEO of Zero Beam Technology, the 3.0 solution plans to integrate cabin, driving, computing, and connectivity into one. In the future, the number of domain controllers will be halved, data bandwidth will be increased by 5 times, harness length will be reduced by 30%, and OTA speed will be increased by 70%; The deep integration of the IoT ecosystem enables vehicles to possess strong self-learning, self evolution, and self growth capabilities, achieving the ultimate intelligent experience of continuous scenes. What makes users happy is that all of this is not just talk on paper. SAIC Zero Beam's Galaxy Intelligent Vehicle Full Stack Solution 3.0, including Zero Beam Galaxy Intelligent Vehicle Operating System ZOS, Zero Beam Galaxy Intelligent Driving Computing Platform ZPD, Zero Beam Galaxy Intelligent Cabin Computing Platform ZCM, and Zero Beam Galaxy Cabin Driving Integration Computing Platform ZXD, will also be the first to be installed on its own models, with plans to mass produce and land in 2025.

The first technology to meet users before the 3.0 solution was Zero Beam Technology, which brought a new technology - VMC vehicle central coordinated motion controller technology. It is based on the central fusion motion control of the entire vehicle, making the cross domain control link of the vehicle shorter. In the state of human or intelligent driving, it can more efficiently control the body and chassis. For example, it can enable vehicles to achieve lateral, longitudinal, and vertical collaborative control, ensuring that the vehicle maintains stability in different driving modes and various road conditions, bringing the ultimate safety and comfort experience. In addition, it can also provide more intelligent scenarios, including the very useful in-situ turning in narrow road conditions and the "crab" mode of four-wheel lateral movement; When turning, the vehicle will more accurately control the different torque releases of the four wheels; In welcome mode, the air suspension actively lowers, making it convenient for users to get on and off, and so on, creating a different intelligent experience for users. It is reported that VMC technology will be first installed on Zhiji models and is planned to be mass-produced and implemented in 2024.

From traditional power to new energy, and then from traditional brands to new forces, it is not an exaggeration to say that SAIC Group should be one of the most flowering and fruiting enterprises. Its subsidiaries include veterans such as Roewe and MG, as well as new generations such as Feifan and Zhiji who have performed outstandingly in the new era. In the future, with the full stack 3.0 of 2025, a high-performance supercomputing platform equipped with cabin and driver integration, deeply integrated with the IoT ecosystem, with strong self-learning, self evolution, and self growth capabilities, SAIC's new products will bring users a seamless integrated intelligent experience in all scenarios.
