Foreword: After 7 years, the CTC battery chassis integration technology developed by zero-run cars was officially unveiled today. According to the car review agency, this is the latest generation of battery pack packaging technology for the first time in the world, and in the words of zero-running cars, this is also a technology for power batteries to enter the 3.0 era.
Global self-developed software and hardware dual innovation
According to Song Yining, general manager of the battery product line of Zero Run Technology, zero run intelligent power CTC technology, that is, cell -to -chassis, refers to the cutting-edge technology of integrated 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 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.
To put it simply, the CTC battery chassis integration technology is to combine the battery with the body chassis. Compared with the second-generation battery packaging technology, the CTC technology that adopts the one-piece tray structure is actually the transformation of the previous structure of the body and the battery pack into a structure that combines the body and the battery pack.
This is like the "evolution" process of mobile phone electric: the first generation of batteries is relatively simple, just a simple assembly of battery packs; The second generation, the current mainstream battery packaging technology, is the use of integrated large module technology, that is, modular assembly and the addition of intelligent management and other systems of the power battery, this generation of batteries will usually be packaged in a battery module, and with steel plates and other materials for packaging.
Adhere to the zero-run car with all other core technologies in addition to the battery cell, the technical idea includes the three major areas of intelligent driving, intelligent cockpit and intelligent power, and CTC technology is an important part of the intelligent power plate.
At a time when the industry is still generally in the transition from the traditional module 1.0 era to CTP large module technology, zero-run cars have taken a step ahead and developed the first domestic CTC battery chassis integration technology that can be mass-produced. "Inspired by the integrated battery design of smart phones, the zero-run battery research and development team began to develop battery and chassis integration technology from 2016, and after 6 years of overcoming difficulties, it finally came out on top in the research and development trend of CTC technology." Song Yining added.
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.
The zero-run C01 redefines the value standard for medium- and large-sized electric cars
It is reported that the C01 is the flagship model of the zero-run car brand upwards, which will further improve the zero-run car product matrix and will soon open its debut and debut in the near future.
From the perspective of the whole vehicle, the vertical space of the vehicle using CTC technology can be increased by 10mm, and the battery layout space can be increased by 14.5%, which can make the space layout in the car more flexible and practical by eliminating the battery superstructure and reducing the redundant structural design.
In terms of endurance, CTC technology has better airtightness than traditional solutions, which can improve battery insulation performance, battery layout space, etc., and at the same time, based on the energy economy management brought by the innovative software application AI BMS big data battery management system, comprehensively improve the vehicle mileage by 10%.
According to the official, with the continuous evolution of CTC technology, the future can achieve "refueling" charging - charging for 5 minutes and lasting more than 200km.
In terms of safety, Zero Run conducted several rounds of rigorous tests for intelligent power CTC technology during the development process, such as bottom ball hitting, extrusion, thermal diffusion, etc., to ensure battery safety, of which 8 safety test results far exceeded national standards; At the same time, based on the AI BMS big data intelligent battery management system, Zero Run can provide users with real-time cloud security protection at the touch cell level, and has been comprehensively improved in terms of battery safety, battery life and battery performance.
On the whole, the CTC battery chassis integration technology can not only reduce costs, but also bring about a 25% increase in body torsional strength, a 10% increase in cruising range, a 20% reduction in body weight, a 10 mm increase in vertical space in the car, a 14.5% increase in battery layout space, and a follow-up compatible 800-volt high-voltage platform and support for the advantages of 400-kilowatt super fast charging; in addition, zero-sports cars said that this technology can achieve the expectation of charging for 5 minutes and lasting 200+ kilometers.
Regarding the achievements of Zero Run in CTC technology, Zhu Jiangming, Chairman of Zero Run Technology, said: "New technologies should not be barriers, but a ladder to drive industrial breakthroughs. At the same time, Zhu Jiangming also announced at the scene that he would share the intelligent power CTC technology free of charge and share the latest achievements of global self-research with the whole industry.
He further 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.
