On Battery Day in September 2020, Tesla released a new package technology CTC (Cell to Chassis) in addition to the release of 4680 batteries, that is, the cancellation of the Pack design and the direct installation of the battery or module on the body. Tesla CEO Musk has said that after adopting CTC technology, the new car is expected to lose 10% weight, the battery life is expected to increase by 14%, and the body parts can be reduced by as much as 370.
As an innovative direction in the electric vehicle industry, although CTC technology can effectively reduce manufacturing costs, the threshold for research and development is almost harsh. For OEMs, they need to have the ability to design batteries; for battery factories, they need to have the ability to design and manufacture chassis. In addition, both parties need to have the ability to highly integrate the three-electric system.
In addition to Tesla, there are only a few companies such as BYD that have a layout in the field of complete vehicles and power batteries, and can explore this technology. But to everyone's surprise, after Tesla, another car company has mastered CTC technology, it is a zero-run car!
On the afternoon of April 25, 2022, the "Intelligent Era • Source Force Awakening Zero-Run Intelligent Power CTC Battery Chassis Integration Technology Conference" was opened in the cloud, and triggered widespread concern and hot discussion in the industry.
What is Zero Run Intelligent Power CTC Technology?
Based on the forward-looking insight into the development trend of technology, when the industry is still generally in the transition from the traditional module 1.0 era to the CTP large module technology, zero-run cars have overcome difficulties after 6 years, and finally came out on top in the research and development trend of CTC technology, and developed the first domestic CTC battery chassis integration technology that can be mass-produced.
Zero-run intelligent power CTC technology, or cell-to-chassis, refers to the cutting-edge technology that integrates the design of batteries, chassis and car bodies to simplify product design and production processes. By redesigning the battery bearing tray, the entire chassis structure of the car body is coupled with the battery tray structure, the installation process is innovated, and the Less is more is truly achieved. By reducing the redundant structural design, the number of parts is effectively reduced, and while improving the space utilization rate and system specific energy, the body and the battery structure complement each other, so that the battery impact resistance and body torsional stiffness are greatly improved.
Second, where are the advantages of zero-run intelligent power CTC technology?
As the latest important breakthrough under the zero-run intelligent power system, zero-run intelligent power CTC technology fully empowers products through dual innovation of software and hardware. At the same time, it also has high adaptation and strong expansion attributes, which can achieve rapid and flexible production, and will be compatible with higher voltage platforms and models of various levels and types in the future, with the potential for continuous evolution.
In terms of space, zero-run intelligent power CTC technology reduces the redundant structural design by canceling the battery superstructure, so that the vertical space of the vehicle is increased by 10mm, the battery layout space is increased by 14.5%, and the space layout in the car is more flexible and practical.
In terms of endurance, zero-run intelligent power CTC technology can comprehensively increase the vehicle mileage by 10%. Moreover, with the continuous evolution of zero-run intelligent power CTC technology, the future will achieve "refueling" charging, that is, charging for 5 minutes and lasting more than 200km.
In terms of performance, zero-run intelligent power CTC technology can increase the torsional stiffness of the vehicle by 25% and achieve 20% weight reduction (coefficient of 2.4), resulting in better driving performance, better chassis response efficiency, and better NVH quietness.
In terms of safety, during the development process, Zero Run conducted several rounds of rigorous tests for intelligent power CTC technology, such as bottom ball hitting, extrusion and thermal diffusion, to ensure battery safety. Among them, 8 safety test results far exceed the national standard. At the same time, based on the zero-run AI BMS big data intelligent battery management system, zero-run can provide users with real-time cloud security protection at the touch cell level, further improving battery safety, battery life and battery performance.
It is understood that zero-run C01 will become the world's first model equipped with zero-run intelligent power CTC technology, that is, no independent battery pack, and the car will also debut and debut in the near future.
Refusal to monopolize
Zero-run intelligent power CTC technology is free and open to share
At this conference, in addition to the release of zero-run intelligent power CTC technology, a solemn thing happened. Zhu Jiangming, chairman of Zero Run Technology, announced that it will be free and open to sharing of intelligent power CTC technology, so that global consumers can share the dividends of technological progress. He said that the development of new energy vehicles can not be built behind closed doors, the rise of the industry is not a one-person thing, exchanges, interconnection is the key to China's automobile to catch up with the world.
This kind of courage and boldness, zero-run cars deserve everyone's praise!
Uncle Che summed up
Through the mass production of CTC technology, zero-run cars have proved with practical actions that on the new track of intelligent electric vehicles, Chinese car brands have stood in the C position. It is believed that in the future, the Chinese automobile brand that "wins the market with technology" will certainly be able to lead the development of the global new energy automobile industry and penetrate Chinese manufacturing into every corner of the world.
