At present, more and more car companies are aiming at the power battery CTC(cell-to-chassis) technology.
On April 25th, Zero Run officially released CTC technology. By directly integrating the battery cells into the chassis of the vehicle, the module in the previous power battery was omitted, and the internal structure of the battery pack was further simplified.
Prior to this, Tesla CEO Musk released the structural battery, namely CTC battery body integration technology, on Tesla Battery Day in September 22. In July 221, at the strategic development conference held by Volvo and Volkswagen Group, both traditional car giants mentioned CTC in unison, and more and more car companies took CTC as the key direction of their future technical route.
At the end of last year, Contemporary Amperex Technology Co., Limited revealed that it planned to launch the fourth generation highly integrated CTC battery system around 225.

Electric vehicle enterprises aim at CTC technology
Public information shows that the power battery in new energy vehicles is a three-level Pack structure of "battery-module-whole package", and the power battery is managed by the battery management system in a hierarchical way. However, it is inevitable that the power battery will occupy too much space and waste space.
In order to make the limited car space can carry more batteries without increasing the overall weight, power battery manufacturers such as Contemporary Amperex Technology Co., Limited and BYD, and car companies such as Tesla and Zero Run are all looking for new solutions-CTC technology.
Song Yining, general manager of Zero Run Technology battery product line, explained: "CTC technology, that is, cell-to-chassis, refers to the cutting-edge technology that integrates the battery, chassis and lower body to simplify product design and production process." To put it simply, CTC technology skips the module and battery pack mechanism, and directly integrates the battery into the automobile chassis, with the upper and lower plates of the chassis as the battery shell and cover plate, so that the battery directly becomes a part of the chassis structure.
On Tesla Battery Day in 22, Musk explained the CTC technology with the image of the wing: "Originally, the plane would put the fuel tank in the wing, but in order to make greater use of the space, it took off the fuel tank and directly stored the fuel with the wing, which could hold more fuel."
According to the zero-run car, CTC technology can increase the battery layout space without changing the body structure. Take the soon-to-be-released zero-run C1 as an example, the layout space can be increased by 14.5%. In the case of the same wheelbase, the vehicle can be equipped with more batteries and get more battery life.
Secondly, because the battery structure is simplified and the battery and vehicle chassis are integrated, the vertical space of the vehicle body can be increased by 1 mm.. In terms of battery life, higher battery space utilization efficiency can improve battery life to a certain extent. On the other hand, due to the reduction of battery structure, an insulation layer can be added between the cockpit and the battery, which can better insulate the battery in winter. Therefore, after equipped with CTC technology, the comprehensive endurance of the vehicle can be improved by 1%.
TF Securities believes that CTC technology is an important development direction of battery technology for electric vehicles in the future. With the increasing demand for convenience and lightweight of electric vehicles, CTC will gradually become an important direction of technology research and development and application.
It is worth mentioning that when the CTC technology was released, Zhu Jiangming, the chairman of Zero Run Automobile, announced that Zero Run Automobile would open CTC technology to the whole industry, hoping that more players would participate and promote the continuous development of the industry together.
CTC is not suitable for all car companies
At present, with the gradual maturity of body design, intelligent cockpit, assisted driving and other technologies, the competition of electric chassis technology is becoming increasingly fierce, and the integration of battery system and drive system and skateboarding of chassis system have become new competition hotspots for electric passenger cars. Among them, the highly integrated battery technology of CTC is one of the core technologies of the new round of electrified chassis.
At the end of 221, Contemporary Amperex Technology Co., Limited revealed that it plans to launch the fourth generation highly integrated CTC battery system around 225, and it is expected to upgrade to the fifth generation intelligent CTC electric chassis system around 228.
Contemporary Amperex Technology Co., Limited said that CTC technology will not only rearrange the batteries, but also be incorporated into the three-electricity system, and optimize power distribution and reduce energy consumption through intelligent power domain controller, with the goal of completing technology development by 23.
in addition, the skateboard chassis that overseas car companies are keen on can also integrate the battery and the electric drive system needed by the whole vehicle on a relatively thin chassis. It is understood that under the skateboard chassis technology, the body above the chassis can be changed at will, and the performance parameters of the chassis can be adjusted according to different customization requirements (passenger cars, commercial vehicles and special vehicles), which has strong compatibility and expansibility.
for car companies, they need to choose between CTC technology which can realize the integration of electric chassis and vehicle-electric separation. CTC can improve the space utilization and chassis passability, and improve the driving experience, but it also faces the disadvantages of high maintenance cost and difficult battery recovery. Tesla's patent shows that after adopting CTC scheme, the battery pack, as a structural part, has higher requirements for rigidity and thermal runaway management.
The most intuitive feeling given to consumers by the vehicle-electricity separation scheme represented by Weilai is the drop in the price of new energy vehicles. At present, the cost of battery accounts for about 25% to 4% of the cost of electric vehicles. The separation of electric vehicles and electric vehicles can make the purchase cost of electric vehicles lower than that of fuel vehicles of the same level and solve the problem of expensive car purchase. This is also more conducive to promoting the sales scale of the main engine factory and further reducing the cost.
some analysts believe that it is extremely risky for the OEM that does not have strong brand technical ability to form explosive models to choose CTC. The market has verified that the battery capacity density is constantly improving, and the high efficiency mode of using a standard battery pack for different models is an inevitable choice for OEMs.
In response to investors' questions about whether the research on CTC technology means not optimistic about the battery replacement mode, whether it will lead to battery replacement and a substantial increase in maintenance costs, Contemporary Amperex Technology Co., Limited said that new energy vehicles are currently being explored in many directions, each technology has its own different characteristics and application scope, and the company is optimistic about the future direction of battery replacement and CTC.

CTC battery chassis integration technology that Tesla and BYD have not mass-produced. Is zero-run ahead?
the answer is yes. It is expected to debut in May, start the pre-sale in June and go on the market in August. Zero Run C1 announced that it will be the first to use CTC battery chassis integration technology and realize mass production of CTC technology.
CTC technology (cell -to -chassis) refers to the scheme that the battery, chassis and lower body are integrated, the body structure is used as the external structure of the battery pack, and the original module and battery pack shell are cancelled. The advantages are that the chassis structure is enhanced, the battery shell is reinforced, and the interior space is optimized. After adopting CTC technology, the vertical space of the whole vehicle is increased by 1mm, the battery layout space is increased by 14.5%, and the interior space layout is more flexible and practical.
CTC technology improves endurance performance. Zero-run CTC technology has better air tightness and improved battery insulation performance. At the same time, based on AI BMS big data battery management system, energy consumption management is more economical and the cruising range is increased by 1%. On the one hand, it can be charged for 5 minutes, and the battery life exceeds 2km. Moreover, the battery life of zero-run C1 can reach 717km.
CTC technology enhances car body rigidity. Zero-run CTC technology improves the torsional stiffness by 25%, and the lightweight coefficient reaches 2.4, an increase of 2%. The higher the torsional stiffness of the car body, the stronger the ability to resist * * * vibration, which means that the whole car can have better driving and control performance and better chassis response efficiency, which can also help NVH performance.
It is reported that BYD's upcoming seal will also adopt CTC battery chassis integration technology, but BYD has not officially announced that Tesla's factory in Europe is also preparing to mass-produce Model Y equipped with CTC battery chassis integration technology, but it has not yet been mass-produced. According to the official announcement, the zero-run C1 is indeed the first vehicle with integrated CTC battery chassis technology for mass production.
the zero-run C1 has a body length of 5m, and is positioned as a medium-sized and large-sized pure electric car. It will have a comprehensive working life of 717km and a "3-second" zero-acceleration capability. It is a highlight to use borderless doors and hidden door handles, and equipped with CTC battery chassis integration technology.
all the models on sale before the zero-run are mainly cost-effective. It is expected that the price of the zero-run C1 will be quite advantageous. Do you think the zero-run C1 will become an explosion after it goes on the market? Zero-run starting CTC battery technology will be open for free * * * Enjoy 3
After the sales volume enters the explosive stage, the technological revolution of new energy vehicles is developing towards a deeper level. The core of the technological revolution focuses on promoting more efficient electrification and higher-level intelligent networking.
As the heart of new energy vehicles, batteries have naturally become the most concerned "role". Whether it is a battery manufacturer or an automobile manufacturer, one of the core tasks now is to do everything possible to build a safer and more energy-intensive power battery at a lower cost.
in addition to making a fuss about the raw materials and material states of power batteries (mainly referring to the electrolyte of batteries), its structure and intelligence have attracted more and more attention from the industry. In September 22, at the Battery Day held by Tesla, Musk once said that in the future, Tesla models will adopt CTC (Battery Chassis Integration) technology, and with integrated die casting technology, 37 parts can be saved, which will reduce the body weight by 1% and reduce the battery cost per kWh by 7%.
In addition, Contemporary Amperex Technology Co., Limited, BYD, Bosch and other automotive giants have also indicated that they are increasing the speed of CTC technology research and development.
but what the industry didn't expect was that such a difficult-to-conquer technology has been mass-produced by a new force in China. Recently, at the zero-run CTC technology conference, zero-run announced that it has taken the lead in mass production of CTC batteries in China. The battery will be first installed on the zero-run C1, the fourth model of zero-run, and mass production will be carried out simultaneously.
So, what is CTC technology? Why are many industry leaders scrambling to develop CTC technology? Why does a zero-run car become a car company that puts technology on the ground?
the rise of CTC technology
who will dominate the ups and downs of global electric vehicle development in the future?
the birth of lithium-ion power batteries dates back to the 199s. In 1997, Nissan manufactured the world's first electric vehicle, Prairie Joy EV, which uses cylindrical lithium-ion batteries. The mileage of this vehicle exceeds 2 kilometers after each charge.
Perhaps Prairie Joy EV let everyone see the hope of the rise of electric vehicles. After entering the 21st century, LG Chem, an internationally renowned company in the materials industry, and BYD, a domestic car company that was not well-known at that time, began to develop vehicle power batteries.
in 29, after the Japanese commercial giant Panasonic successfully acquired Sanyo Electric, its position in the global battery industry rose rapidly, and it became the only supplier of power batteries for Tesla for many years.
after 21, as China began to vigorously support the new energy automobile industry, the power battery as a core component was highly valued. Domestic battery companies such as BYD and Contemporary Amperex Technology Co., Limited, with the support of the state, have invested heavily in research and development. Supported by the huge domestic market, Contemporary Amperex Technology Co., Limited and BYD have rapidly grown into global leading enterprises in the installed capacity of power batteries.
by 218, Contemporary Amperex Technology Co., Limited's global installed capacity will reach 23.54Gwh, and BYD's global installed capacity will reach 11.6Gwh, ranking first and third respectively. In 221, Contemporary Amperex Technology Co., Limited's global installed capacity increased to 96.7Gwh and BYD's global installed capacity increased to 26.3Gwh, ranking first and fourth respectively.
For many years, battery manufacturers all over the world have been trying to improve the energy density of power batteries through various ways, but the breakthrough of battery material science is not an overnight success, so manufacturers are counting on how to improve the performance by improving the battery structure and improving efficiency through control software based on existing materials.
in 219, CTP battery, the power battery representing the 2. era, began to appear. Compared with the previous power battery, CTP battery removes the module, which improves the space utilization rate inside the battery pack, thus improving the comprehensive performance of the battery. Nowadays, CTP has become the mainstream power battery technology in the world. At this stage, China battery enterprises are at the forefront of the industry by virtue of the advantages accumulated before.
just one year later, in 22, Tesla announced that the future Tesla models will adopt CTC (battery chassis integration) technology. Other battery factories and car companies have also begun to study CTC technology.
CTC is cell -to-chassis, which is a brand-new power battery technology that directly loads the batteries originally wrapped in battery packs and modules into the automobile chassis, and can be regarded as the version 3. power battery.
Mastering the third-generation battery technology has also become a battleground for global car companies and battery companies.
besides battery technology, CTC technology is more closely related to the structural design and manufacture of the whole vehicle, especially the chassis. Therefore, after the third generation of power batteries, China power battery giants who only have battery technology will encounter great challenges in the integrated design and manufacture of batteries and chassis because they do not have the ability to design and manufacture the whole vehicle.
at the same time, if China car companies didn't take over the baton of the development of power battery to CTC technology, the technology and market share advantages established by China power battery companies and even China electric vehicle companies in recent years may be subverted by foreign brands with strong battery and vehicle technology, such as Tesla.
China's automobile industry wants to achieve the grand goal of overtaking foreign automobile brands in corners with the help of electric vehicles. Under Musk's rhetoric that "Tesla will sell 2 million vehicles a year", there is also a little worry.
To the surprise of many people in the industry, it is a China electric car brand-Zero Run Car that has been doing research and development in a low-key way. Say, "Accident
