Zero-run starting CTC battery technology will be provided free of charge. According to official information, the zero-run C0 1 is indeed the first model to mass-produce CTC battery chassis integration technology. Zero-run starting CTC battery technology will be provided free of charge.
Zero-run start CTC battery technology, will be free to open * * * enjoy 1 At present, more and more car companies are aiming at CTC(cell-to-chassis) technology.
On April 25th, Zero Run Auto officially released CTC technology. By directly integrating the battery cells into the vehicle chassis, the modules in the previous power battery are omitted, and the internal structure of the battery pack is further simplified.
Prior to this, Tesla CEO Musk released a structural battery CTC battery body integration technology on Tesla Battery Day in September 2020; In July, 20021,at the strategic development conference held by Volvo and Volkswagen Group, two 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 Ampere Technology Co., Ltd. revealed that it plans to launch the fourth generation of highly integrated CTC battery system around 2025. The picture shows the CTP technology displayed by Contemporary Ampere Technology Co., Ltd. filmed by reporter Li Shuo.
CTC Technology for Electric Vehicle Enterprises
According to public information, the power battery in new energy vehicles is a three-level package structure of "battery-module-complete package", and the power battery is managed by the battery management system at different levels. But the power battery will inevitably take up too much space and waste space.
In order to make the limited car space carry more batteries without increasing the overall weight, contemporary power battery manufacturers such as Amperex Technology Co, Limited and BYD, as well as companies such as Tesla and Zero Run, are 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." Simply put, CTC technology skips the mechanism of module and battery pack, 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 2020, 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 removed the fuel tank and directly stored the fuel with the wing, so that more fuel could be loaded."
Zero-run cars show that CTC technology can increase the battery layout space without changing the body structure. Taking the upcoming zero run C0 1 as an example, the layout space of 14.5% can be increased. In the case of the same wheelbase, the vehicle can be equipped with more batteries and get longer battery life.
Secondly, due to the simplified battery structure and the integration of the battery and the vehicle chassis, the vertical space of the vehicle body can be increased by 10mm. In terms of battery life, higher battery space utilization efficiency can improve battery life to some extent. On the other hand, due to the reduction of battery structure, an insulating layer can be added between the cockpit and the battery, which can better insulate the battery in winter. Therefore, with CTC technology, the comprehensive endurance of the vehicle can be improved by 10%.
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 CTC technology was released, Zhu, 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 jointly promote the sustainable development of the industry.
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 the skateboarding of chassis system have become new competition hotspots of 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 20021,Contemporary Ampere Technology Co., Ltd. revealed that it plans to launch the fourth generation of highly integrated CTC battery system around 2025, and it is expected to upgrade to the fifth generation of intelligent CTC electric chassis system around 2028.
Contemporary Ampere Technology Co., Ltd. said that CTC technology will not only rearrange batteries, but also be incorporated into three major power systems, and optimize power distribution and reduce energy consumption through intelligent power domain controllers, with the goal of completing technology development by 2030.
In addition, the skateboard chassis that overseas car companies are keen on can also integrate the battery and 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 replaced 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, it is necessary to choose between CTC technologies that can realize the integration of electric chassis and the separation of vehicles and electricity. CTC can improve space utilization, chassis passability and driving experience, but it also faces the disadvantages of high maintenance cost and difficult battery recovery. Tesla's patent shows that after adopting the 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 decline in the price of new energy vehicles. At present, the cost of batteries accounts for about 25% to 40% of the cost of electric vehicles. The separation of electric vehicles from electric vehicles can make the purchase cost of electric vehicles lower than that of the same class of fuel vehicles, 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 OEMs that do not have strong brand technology capabilities to form explosions 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 this regard, contemporary Amperex Technology Co., Ltd. responded to the question whether the research on CTC technology by investors means that the battery replacement mode is not optimistic and whether it will lead to a substantial increase in maintenance costs, saying that new energy vehicles are being explored in many directions, and each technology has its own different characteristics and application scope. The company is optimistic about the future direction of battery replacement and CTC.
Zero Run introduces CTC battery technology, which will be free to enjoy the CTC battery chassis integration technology that Tesla and BYD have not mass produced. Zero runs ahead?
The answer is yes. It is expected to debut in May, pre-sale will begin in June, and Zero Run C0 1 will be launched in August, announcing the first use of CTC battery chassis integration technology and the first realization of 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 enhanced chassis structure, reinforced battery shell and optimized internal space. After adopting CTC technology, the vertical space and battery layout space of the vehicle increased by 10mm and 14.5% respectively, making the interior space layout 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 cruising range is increased by 10%. On the one hand, it can be charged for 5 minutes and has a battery life of more than 200km. In addition, the zero run C0 1 endurance can reach 7 17km.
CTC technology enhances car body rigidity. Zero-run CTC technology improves the torsional stiffness by 25%, and the lightweight coefficient reaches 2.4, increasing by 20%. 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 handling performance and better chassis response efficiency, which can also help NVH performance.
It is reported that BYD's upcoming seals will also adopt CTC battery chassis integration technology, but BYD officials have 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 achieved mass production. According to official information, the zero-run C0 1 is indeed the first model to mass-produce CTC battery chassis integration technology.
The zero-run C0 1 body length is 5 meters, and it is positioned in medium and large pure electric vehicles. It will have a comprehensive working life of 7 17km and a zero acceleration capability of "3 seconds". It is a highlight to adopt borderless doors, hidden door handles and integrated technology with CTC battery chassis.
The models sold before the zero run are mainly cost-effective. It is expected that the price of zero run C0 1 will be quite advantageous. Do you think zero run C0 1 will become an explosion after it goes on the market?
Zero-start CTC battery technology will be open for free * * * Enjoy 3 After the sales volume has entered the explosive stage, the technological revolution of new energy vehicles is developing to a deeper level. The core of the technological revolution focuses on promoting more efficient electrification and a higher level of intelligent networking.
As the heart of new energy vehicles, batteries 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 make a safer and more energy-consuming power battery at a lower cost.
In addition to making a fuss about the raw materials and material state 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 2020, at the Battery Day held by Tesla, Musk said that in the future, Tesla models will adopt CTC (Battery Chassis Integration) technology. By integrating die casting technology, 370 parts can be saved, which will reduce the weight of the car body by 65,438+00% and the battery cost per kWh by 7%.
In addition, automobile giants such as Contemporary Ampere Technology Co., Ltd., BYD and Bosch also indicated that they are increasing the speed of CTC technology research and development.
But what the industry didn't expect was that such an insurmountable technology has been mass-produced by a new force in China. Recently, at the Zero Run CTC Technology Conference, Zero Run announced that it was the first to realize mass production of CTC batteries in China. The battery will be installed on the fourth model of zero-run C0 1 at first, and will be mass-produced 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 to the ground?
The rise of CTC technology
Who will dominate the development of global electric vehicles in the future?
The birth of lithium-ion power batteries dates back to the 1990s. 1997 Nissan manufactured the world's first electric vehicle Prairie Joy EV using cylindrical lithium-ion batteries, with a mileage of more than 200 kilometers after each charge.
Perhaps the grassland Joy EV let everyone see the hope of the rise of electric vehicles. After entering the 2 1 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 2009, after the Japanese commercial giant Panasonic successfully acquired Sanyo Electric, its position in the global battery industry rose rapidly, becoming the only power battery supplier for Tesla for many years.
After 20 10, as China began to vigorously support the new energy automobile industry, the power battery as the core component was highly valued. Domestic battery companies such as BYD and Contemporary Ampere Technology Co., Ltd. have invested heavily in research and development with the support of the state. With the support of the huge domestic market, Contemporary Ampere Technology Co., Ltd. and BYD have rapidly grown into global leading enterprises in the installed capacity of power batteries.
By 20 18, the global installed capacity of Contemporary Ampere Technology Co., Ltd. will reach 23.54Gwh, and that of BYD will be 1 1.6Gwh, ranking first and third respectively. In 20021year, the global installed capacity of Contemporary Ampere Technology Co., Ltd. increased to 96.7Gwh, and that of BYD 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 channels, but the breakthrough of battery material science is not achieved overnight, so manufacturers are pinning their hopes on how to improve the performance on the basis of existing materials, such as improving the battery structure and improving efficiency through control software.
In 20 19, CTP battery, the power battery representing the 2.0 era, began to appear. Compared with the previous power battery, CTP battery removes modules, 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 present, China battery enterprises are at the forefront of the industry by virtue of the advantages accumulated before.
Just one year later, in 2020, 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 (cell -to-chassis) is a brand-new power battery technology, which can be regarded as version 3.0 power battery by directly loading the batteries originally wrapped in battery packs and modules into the automobile chassis.
Mastering the third-generation battery technology has also become a battleground for global car companies and battery companies.
In addition to 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 don't take over the baton of developing power batteries to CTC technology, the technology and market share advantages established by China power battery companies and even China electric car companies in recent years may be subverted by foreign brands with strong battery and vehicle technology, such as Tesla.
China automobile industry wants to achieve the grand goal of overtaking foreign automobile brands in corners with the help of electric vehicles. Under the rhetoric of Musk's "Tesla's annual sales of 20 million vehicles", there is also a little worry.
To the surprise of many people in the industry, it is a China electric car brand that has been doing research and development in a low-key way-Zero Run Car. We say "accident" because in China's automobile industry, there are four traditional automobile enterprises with profound backgrounds, followed by three powerful new forces, Wei Xiaoli. Even BYD, the hottest domestic electric vehicle, has not yet achieved mass production of CTC technology.
At the zero-run smart power CTC technology conference on April 25th, zero-run not only took the lead in releasing mass production CTC technology. At the same time, Zhu Yexuan, chairman of Zero Run Technology, announced that all CTC technologies will be opened for free, and his mind to promote the common development of the whole industry is commendable.
Why is it zero operation?
Compared with BYD, Contemporary Amperex Technology Co., Ltd. and other industry giants, why did Zero Run become the first car company in China to put this technology to the ground?
First of all, it stems from the entrepreneurial spirit that Zhejiang businessmen dare to think and do.
Zhu 20 16, the founder of Zero Run Technology, was inspired by the battery integration of smart phones: Since smart phones can make battery integration thinner without affecting performance, why can't electric vehicles learn from this idea?
At that time, there was no voice about this technology in the industry. However, due to the technical level of the whole industry at that time, it was difficult to integrate the design of 18650 battery, and it was even more difficult to realize the integrated design of the battery body in one step.
Zero runners are not discouraged. First, they conquered the second generation CTP large module technology in the industry earlier on 20 18, and then mobilized many elite soldiers such as battery, chassis, test and verification, technology and so on from 20 19. After two versions of CTC technical verification scheme, they finally finalized the mass production scheme of CTC at the end of 20021,and it was carried out in April 2022.
Secondly, it stems from the strong technical foundation accumulated by global self-research for a long time.
Since the establishment of 20 15, Zero Run has always adhered to the principle of technology, and all the core systems and electronic components of intelligent electric vehicles have been independently developed, designed and manufactured. Not long ago, Zero Car revealed its achievements in various technical fields of automobiles in its listing prospectus submitted to the Hong Kong Stock Exchange.
According to the data, in the most critical component battery, only the battery of the zero sports car has been purchased, and other modules, battery packs, body integration and integrated design have always been completed by ourselves. This is also the fundamental reason why zero-run cars can gain an advantage in the latest generation of battery technology before more professional battery manufacturers.
It is understood that the zero-run CTC technology integrates the battery with the lower body, reducing the number of parts and simplifying the product design and production process. While improving the space utilization rate and specific energy of the battery system, the structure of the car body and the battery is complementary, which greatly improves the impact resistance of the battery and the torsional stiffness of the car body.
CTC technology not only innovates in hardware, but also empowers in software algorithm. Zero-run car said that the AI BMS big data intelligent battery management system independently developed by the company has also begun to be applied to the latest models. Using this technology, the BMS at the vehicle end can be detected online in real time, and the big data management of the battery can be realized in the cloud. Through AI deep learning, full-time active protection of the cloud at the vehicle end can be realized, bringing users a long-life, high-efficiency and high-security power battery system.
As the saying goes, wine is not afraid of the depth of the alley. In 2021-1February, the cumulative delivery volume of zero-running cars was 43 12 1, up 278.6% year-on-year. In the first quarter of 2022, the cumulative delivery of zero-running cars was 29,664, a year-on-year increase of 46,544. As a result, the new power pattern of car-making is changing from "three strong" to "five tigers".
At the historical moment when both technology and sales support the brand upward, C0 1, the next heavyweight model with zero running, is about to enter the "battlefield". Thanks to CTC technology, C0 1 has the confidence to become an explosion. CTC technology cancels the upper structure and redundant components of the battery, and adopts the body structure as the external structure of the battery pack, which not only brings stronger body structure strength to C0 1, but also brings more driving space, stronger handling performance and higher safety guarantee.
