On the afternoon of April 25, Zero Run Technology officially released the first mass-produced CTC battery chassis integration technology in China, which can increase the battery layout space of the vehicle by 14.5% and comprehensively increase the mileage of the vehicle by 10%. This technology will be the first mass production application on the zero-run C platform electric medium and large sedan zero-run C01, and the zero-run C01 will soon open its debut and debut.
From CTP to CTC
As the core component of an electric vehicle, the importance of power batteries is self-evident.
The performance improvement of power batteries basically follows two routes, one is the material route, through the breakthrough of basic disciplines such as physics and chemistry, bringing about an increase in energy density; the other is the engineering route, based on the existing battery technology, through engineering means, to achieve the performance of electric vehicles.
In terms of materials, the current electric vehicles are generally equipped with lithium-ion batteries, it is difficult to improve the performance of batteries through material innovation, although now batteries such as sodium-ion batteries have also begun to sound, but there is still a long way to go from the real scale mass production applications.
Improving battery performance through engineering means has become a more realistic and effective method chosen by most battery companies and car companies, such as the current CTP (Cell To Pack) technology, that is, module-free technology, which is applied in large-scale applications.
The original power battery installed on the car is composed of three layers of battery cells, modules and packages, while CTP technology skips the intermediate mitigation of the battery module, and integrates the battery cell directly into the battery pack, thereby improving space utilization and production efficiency, bringing about an increase in energy density, and reducing the manufacturing cost of power batteries.
CTC technology is a step closer to CTP technology and a major trend in the development of electric vehicles. CTC, or cell-to-chassis, refers to the integrated design of batteries, chassis and car bodies, simplifying product design and production processes.
Song Yining, general manager of the battery product line of Zero Run Technology, said: "Zero Run Intelligent Power CTC Technology has innovated the installation process by redesigning the battery bearing tray, coupling the entire chassis structure of the car body with the battery tray structure, and truly achieving Less is more. By reducing the redundant structural design, the number of parts can be effectively reduced, and while improving the space utilization rate and system specific energy, the body and battery structure complement each other, so that the battery impact resistance and body torsional stiffness are greatly improved. ”
What does zero-run CTC technology bring?
The model equipped with zero-run intelligent power CTC technology will be the C platform electric medium and large sedan zero-run C01, which will soon open its debut and debut, and take the lead in mass production application. Zero-run C01 is the flagship model of the zero-run car brand upwards, and it will also further improve the product matrix of zero-run.
It is worth mentioning that the zero-run intelligent power CTC technology applies the body structure as the external structure of the battery pack, canceling part of the structural design of the battery pack, in this sense, the zero-run C01 equipped with zero-run intelligent power CTC technology will become the world's first electric vehicle without an independent battery pack.
CTC technology also brings a full range of improvements in space, endurance, performance and safety to the zero-run C01 and models equipped with this technology after zero-run.
First of all, CTC technology reduces redundant structural design by eliminating the battery superstructure, so that the vertical space of the vehicle is increased by 10mm, and the battery layout space is increased by 14.5%.
Secondly, zero-run intelligent power CTC technology has better airtightness than traditional solutions, and based on the energy economy management brought by the innovative software application AI BMS big data battery management system, the vehicle mileage is comprehensively improved by 10%. In the future, it can also achieve fast charging performance of charging for 5 minutes and a battery life of more than 200km.
In terms of performance, it can bring a 25% increase in torsional stiffness and a 2.4% reduction in weight factor for the entire vehicle, an increase of 20%. The higher the torsional stiffness of the body, the stronger the resistance to resonance, which means that the vehicle can have better driving performance, better chassis response efficiency, and can also contribute to NVH performance.
Finally, in terms of safety, zero-run intelligent power CTC technology has undergone nearly 30 rigorous tests such as bottom ball hitting, extrusion, thermal diffusion, etc., of which 8 safety test results far exceed national standards to ensure battery safety. In addition, the intelligent battery management system based on zero-run AI BMS big data can provide users with real-time cloud security protection at the battery cell level, and comprehensively improve battery safety, battery life, battery performance and other aspects.
The first batch of "eating crabs" will also be free and open to share
CTC technology is highly valued by the industry, CATL has said that it will launch the technology in 2025, volvo and Volkswagen also regard it as an important technology route. At present, only Tesla in the world has used CTC technology in production cars, and the time is on the Recently Opened Texas factory.
As a new second-tier force in China, the delivery volume of Zero Run in March has just exceeded 10,000, why can it become the first batch of car companies to mass-produce and apply CTC technology? This is inseparable from the "global self-research" route that Zero Run has always adhered to, and Zero Run believes that this is a short-term difficult and long-term correct path.
I am an engineer myself, attach importance to research and development, like innovation, zero run since the beginning of its inception, it has established a global self-development route in the field of core technology to take the integration of software and hardware. Build smart electric cars as an electronic product. Zhu Jiangming, chairman of Zero Run Technology, said so.
In 2016, Zhu Jiangming was inspired by the transformation of mobile phone batteries from separate to fuselage integration, and took the lead in proposing the CTC concept. As one of the first people to eat crabs, Zhu Jiangming set up an inter-departmental project team to personally supervise the progress of the project.
From 2019 to 2020, after two versions of the engineering practice program of CTC technology, Zero Run initially completed the concept of CTC program. At this time, the space utilization rate increases by 5%-10%, and the stiffness of the vehicle increases by 10%.
After continuous testing, demonstration and improvement, by this release, Zero Run officially became one of the earliest enterprises in the industry to realize the integrated mass production technology of CTC battery chassis.
What is more noteworthy is that zero running will be free and open to intelligent power CTC technology, so that global consumers can share the dividends of technological progress. Zhu Jiangming 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 catch-up with the world.
Che Yun Summary:
Once upon a time, Zero Run was accused of empty talk and satellites for surpassing Tesla's rhetoric in the field of intelligent driving within three years. Nowadays, Zero Run has kept up with Tesla's pace on the mass production application of CTC technology, so that the outside world has to look at it with surprise.
The "global self-research" strategy that Zero Run has always adhered to is also entering the stage of blossoming and bearing fruit.
