One platform, two architectures, a new car, a white paper, a new logo, and a new brand. AutoWiki seems to be attending not just a press conference, but more like a "coming-of-age ceremony". Jiangjiang Automobile Group's 17-year-old "coming-of-age ceremony".
On the inside, every detail of the past 17 years is told, and outside, the fruitful results of the past 17 years are displayed. Especially when you enter from outside the venue, you need to pass through a three-sided building. The corridor built with an LED screen wall flashes with codes and digital symbols, which seems to clearly convey a central idea - Jiangxi Automobile Group must be indispensable in the decisive battle for new energy in the second half.
"5, 4, 3, 2, 1", as the audience at the scene said in unison, on April 12, Jiangxi Automobile Group's new passenger car standard unveiling and new brand strategy conference were officially held in Hefei.
Wait, what is written next to the countdown?
It turns out that there are four small characters next to each number, 5, 4, 3, 2, and 1. They are intelligent strategy, intelligent layout, intelligent development, intelligent manufacturing, and intelligent network connection. Obviously, This is JAC Group’s thinking on intelligence, as Xiang Xingchu, Party Secretary, Chairman and General Manager of JAC Group Holding Company, said: “In such a period of great change, JAC Group should have great potential and will certainly achieve something. As."
Why is it 17 years old?
Perhaps you don’t know that Jiangxi Automobile Group has been adhering to iterative research and development since 2007. After 9 generations of technology and 4 generations of products, it has accumulated leading three-power core technology. Since 2016, , insisting on open cooperation, jointly jointly with Volkswagen and NIO, formed the international competitiveness of vehicle industrialization. Since 2019, it has comprehensively deployed intelligence and strategically cooperated with technology companies such as Huawei and iFlytek. It has built an intelligent ecosystem, and today it has exactly 17 years of industrial technology accumulation and tens of billions of kilometers of market practice.
It is worth mentioning that at the press conference, Auto Wiki also observed two small details, one is the AI ??virtual assistant "Eileen", and the other is the dean of the Intelligent Network Alliance Institute of Jiangxi Automobile Group Technology Center "ChatGPT" mentioned by Liu Jiangbo.
Car Wiki would like to say that maybe "Eileen" doesn't know you best at the moment, and Jiangxi Automobile Group and "ChatGPT" are definitely in a running-in period, but don't worry, this is just a From the beginning, with JAC Group’s insight and execution ability to keep up with the development trend of the industry, we have reason to believe that under the new track and new pattern of the smart car industry, and in the era of the Internet of Everything, it will definitely provide users with Providing safer, freer and more enjoyable mobility solutions. After all, "no cars can be built without intelligence" comes from JAC.
The background is really big
On the spot, Jianghuai Automobile Group officially released the new energy passenger car brand "JAC Ywei", and also brought the world's second-generation pure electric vehicle Platform "DI Platform".
Among them, the background of this "DI platform" is indeed not small. Car Wiki calculated it and Xia Shunli, general manager of Jiangxi Automobile Group New Energy Passenger Vehicle Company, took the stage to introduce it for nearly 30 minutes. There were 15 Minutes have been spent talking about this "DI platform". Just how much effort of Jiangxi Automobile Group is contained here, let's listen to the car wiki to explain it slowly.
1. "0 Thermal Diffusion Honeycomb Battery".
It is understood that JAC Yttrium is based on the bionic design of cylindrical battery cells. After long-term practice and theoretical exploration of 4 generations of technology and 150,000 vehicles, it adopts the three cores of thermal isolation, electrical isolation and thermoelectric decoupling. technology, developed a system-level battery pack thermal runaway solution, and named this solution "zero thermal diffusion cellular battery".
Why choose cylindrical batteries? Xia Shunli explained that because the interface of cylindrical batteries is more stable, safer and easier to control, and in the past 10 years, honeycomb batteries have owned more than 200 invention patents and won the honor of Chinese industrial enterprises. The first prize for innovation achievements, the first prize for provincial science and technology progress, and the provincial gold medal for invention patents are really a reflection of hard work.
Two, "0-power out-of-control safety system".
Through long-term practice accumulation, the DI platform has formed a complete torque safety monitoring and processing strategy system in the software, ensuring that the vehicle will not appear in various usage scenarios such as driving, parking, charging, and remote control. Abnormal, unexpected acceleration and brake failure and other power loss phenomena are ensured to ensure the safety of people and vehicles."
Third, "nine-in-one electric drive".
This level of integration is very It is higher, which means that everything from the motor, motor controller to reducer, from DC/DC, charger, external discharge, to high-voltage power distribution, as well as PTC controller and super flash are all integrated together, and the structure, Hardware and software are integrated with each other, and the electric field, magnetic field, and thermal field are also coupled with each other, which makes its mass power density as high as 5.5 kilowatts per kilogram and the power range of 70-150 kilowatts. Compared with distributed ones, the volume and weight are , the cost is reduced by 30%.
Four, "Super flash charging based on 46 large cylindrical cells"
According to Xia Shunli, "JAC is the first to develop the 46 series of large-scale batteries in China. Cylindrical electrodeless battery cells and precision laser welding group technology achieve an exponential reduction in battery internal resistance and a reduction in charging heat of more than 40%. Coupled with the battery's efficient intelligent temperature control system, it can achieve a battery life of 300 kilometers after 10 minutes of charging, which is twice as fast as ordinary fast charging."
Finally, there is also a "global thermal management system" and "the smallest in its class". Turning radius", "Smart entertainment cockpit", "0-impact driving experience", "Yttrium for Pilot intelligent assisted driving", due to space reasons, the car wiki will not go into details. In short, you only need to remember, "safer, "More efficient, freer, and easier to drive" is the core value of this platform.
Where is the confidence?
In fact, as soon as Auto Wiki arrived at the conference site, they saw the exhibition hall The "Yttrium 3" placed next to the left hand side of the car has to be said that this model is very eye-catching, and the quality is online. It adopts an upper and lower color matching design, round rearview mirrors and petal-style wheels. You can’t help but look at it more.
Is this the end?
Of course not. It is understood that JAC Yttrium will release 4 blockbuster products in 5 years. , in addition to Yttrium 3, there are also Yttrium X3, Yttrium 5 and Yttrium X5. Among them, Yttrium 3 is an intelligent pure electric A-class car, Yttrium X3 is positioned as an intelligent pure electric A-class SUV, and Yttrium 5. Heytrium Wei X5 is positioned as a smart pure electric coupe and SUV. It has an ultra-long battery life of 800 kilometers and a super flash charge of 300 kilometers in 10 minutes.
Hearing this, some people may question it. The first product has not yet been officially launched and delivered. There is not even 1. How did it come about 2, 3, and 4? Don’t worry, let Liu Jiangbo, dean of the Intelligent Network Joint Institute of Jiangxi Automobile Group Technology Center, tell us that as a domestic The earliest car company to start the industrialization research and development of electric vehicles, Jiangxi Automobile Group, what aspects has it been working on in the past ten years?
First of all, according to his introduction, we know that Jiangxi Automobile Group focuses on the environment. With 6 core technologies and 5 revolutionary technologies such as sensing, target detection and tracking, we have created the "Anhui Provincial Key Laboratory of Automotive Intelligent Network Technology". This laboratory is the first intelligent network recognized by CNAS in China. It is also the only designated intelligent driving demonstration operation and test base in Hefei City.
Furthermore, they have joined forces with 7 well-known universities and research institutes, including the University of Science and Technology of China, the Chinese Academy of Sciences, and the Hefei Research Institute. The company has completed 10 major provincial and ministerial scientific research projects, formulated 24 national industry standards, and authorized 194 invention patents.
In addition, in terms of highway safety protection technology, 60 real vehicles have been collected. With more than 10,000 kilometers of data, 5,500 simulation scenarios were constructed. Second, the advanced assisted driving system simulation verification materials were identified as leading in the country. Third, the AEB control algorithm was continuously iterated to achieve high-speed AEB to actively reduce the vehicle speed by 60 kilometers per hour, while the industry is Around 45, it can be said that it greatly reduces the speed of high-speed driving, reducing the risk of vehicle rear-end collisions and the risk of driver injury.
Also, in terms of high-speed piloting auxiliary technology, Jiangxi Automobile Group has invested more than 300 engineers in continuous research and development for 4 years, carried out more than 800,000 kilometers of reliability verification, and achieved 16 core technologies. invention patent. According to Liu Jiangbo: “Our system has 3 kilometers of road detection, 18 driver attention model tracking, three-dimensional human-machine driving mode, and a high-precision of 7 centimeters in the entire highway area of ??the vehicle. Positioning, fast path planning in 7 milliseconds, path tracking accuracy of 20 centimeters, and a user takeover of 277 kilometers, which is more than twice the industry leader.”
Finally, the smart cockpit for human-machine driving. Liu Jiangbo showed us the Volkswagen Anhui Zhifu Logistics Project delivered on April 6. You must know that the self-driving shuttle bus is Ankai’s third-generation L4 self-driving bus that integrates cutting-edge technology. There are 80 self-driving buses. The car can be said to have started the first urban open road demonstration operation in China.
The strongest circle of friends
When building a car, the more friends you have, the better, and the better you are, the better.
Auto Wiki observed that in addition to JAC’s own people attending today’s press conference, there were also iFlytek, Horizon, Huawei, and even Liu, deputy secretary-general of the China Association of Automobile Manufacturers. Yan took the stage to deliver a speech.
As Xiang Xingchu said at the meeting, “We are working with the world’s top intelligent talents and partners to provide users with smart cars with the ultimate experience, and transform our deep understanding of users’ smart information into great products. Brands and classic products will eventually become witnesses and service providers of users’ better lives.”
So, you will see that in the next five years, Jiangxi Automobile Group plans to introduce more than 5,000 experts and technical backbones in the intelligent field through "intellectual introduction actions" based on the existing R&D team. , PhD and other R&D experience, among which, software development talents will be increased to 40.
You will see that in the next five years, Jiangxi Automobile Group’s cumulative R&D investment in the field of intelligent technology will reach more than 12 billion yuan.
You will also see 19 overseas start-up factories established around the world, as well as more than 3,000 sales outlets and 27 smart manufacturing bases.
And this is the biggest confidence that JAC Group has in facing the new energy track in the second half.
