Automotive Black Technology Chapter 1043: ：The original dream

In fact, although Li Fanyu's thoughts may appear open and bright, his thoughts are quite simple.
"In the past, there was nothing we could do. Of course we had to pursue and fight if we had nothing. Now that I have a position in the Chinese market, of course I have to fight with them!" Li returned to Tiancheng and joined the I8 project. Fan Yu told the engineers this.
During this period of departure, several components of I8 have begun to take shape.
According to the previously set R&D plan, Xu Fufang has led the team to roughly finalize the chassis part, and based on Li Fanyu's cost control and other requirements, the overall cloth and battery, electronic control, and body weight ratio Made further optimizations.
The power aspect should have been completed by Liu Qing's team, but because the R&D center already had a ready-made wheel hub motor. Therefore, Liu Qing's team had to temporarily split and allocate a part to combine with Xu Miao and others who had previously started the development of "gyro" hub motors. Because of Li Fanyu's structural design using his design expertise, a set of finished products has been manufactured and is now being tested.
According to everyone’s original research and development goals, the weight of the I8 vehicle needs to be controlled within 2000KG. The acceleration time is at least within 0-100KM/h6.5S. Because it is a sports car, the loading performance requirements are low, and it is considered to be within 800KG. In this way, the maximum allowed weight is 2800KG.
The battery is readily available. According to the body layout standards, the I8 pure electric battery can be loaded with a battery space with a maximum length of 0.8m, a width of 1.2m, and a maximum volume of 0.56 cubic meters. However, this space needs to be considered for the placement of the radiator, so according to Xu Fufang's design, it is initially planned to be equipped with two sets of super molten metal battery packs.
Based on the current hub motor power, the I8 can have a maximum range of 320KM when the battery pack is fully charged and the body is fully loaded.
With this kind of battery capacity, when equipped with a 400V, 16A standard electric pile, the charging time can be shortened to 15 minutes for 60% fast charging, and the 0-100% charging time can be 60 minutes. Under 200V10A household power, the two battery packs can be fully charged within 3 hours through the household power conversion charger that Wang Yu's team has previously designed for super molten metal battery packs.
This is basic performance.
On this basis, in order to implement the principles of "green environmental protection, easy-to-use innovation and customer use economy" formulated by the team. On the electronic control system, the R&D team did a lot of tricks.
According to the group marketing department’s user survey of pure electric models on the market, especially the two TSL models, 86% of the users who choose pure electric models are restricted by license plates such as Beijing, Shanghai, Guangzhou and Shenzhen. Lottery bidding is used to obtain first-tier city users who have difficulty traveling and have green channel policies for new energy vehicle license plates.
As we all know, these four international metropolitan cities with a population of more than 10 million are all areas hardest hit by traffic congestion.
In response to such characteristics, as the I8 is positioned the same as Pallwy, the electronic control R&D team has carried out a series of model innovations;
For example, to cope with traffic jams, a low-power consumption mode similar to the automatic sleep and wake-up of a mobile phone is added. Electronic control solutions such as energy-saving mode at low speed to reduce power consumption and improve battery life.
Furthermore, according to market research reports, approximately 54% of pure electric car users are female users aged 22-32 years old.
In order to win the "hearts" of this type of users, the R&D team has further optimized the I8's control mode;
In addition to integrating Baiwei Entertainment’s pattern recognition technology previously used on high-end models such as A4, 6, and 8 Mini into the I8, it also adds basic intelligent control functions such as automatic parking. It also relies on the power layout plan driven by 4x4 wheel hub motors, which is designed to greatly increase the turning angle in a small space, and even make U-turns on the spot for female users who are familiar with "stream of consciousness driving".
Li Fanyu, who returned to Tiancheng, was quite satisfied after seeing the progress of the R&D team and the results achieved at this stage.
In the small conference room of the R&D center.
Li Fanyu put down the information on the current research and development progress in his hand and smiled at the three top students sitting opposite: "Well done. The current progress and results are really beyond my expectation."
Hearing Li Fanyu's praise, Liu Qing raised her nostrils, "That's right, you don't even look at who is leading this project. Our three brothers have been separated by you and the group's business for a long time, and we are reunited this time. Of course, the whole small universe must explode."
Xu Fufang laughed, "Actually, the more important thing is that the meaning of the I8 car is different. Think about that time in Germany, when we five students with no reputation and had not yet left school, when we came up with this design The cold looks and treatment I received made me feel angry."
Wang Yu obviously agreed with this statement, "My enemy. To be honest, when we were accused of plagiarism in Munich, the competition side so easily believed what those people from Dongda University said about knocking off our I8. I will never forget it in my life. To this day, I can still remember the kind of thing that the competition team was like at that time... Although we can't find too conclusive evidence, based on the ability of you Chinese students, you probably plagiarized. Attitude. After our Zhengxin developed, I wanted to suggest to you several times that we should reshape our original dream of I8 and put it on the market to prove ourselves again. Now that we finally have the opportunity, of course I feel full of energy. ! ”
"Oh, it feels like yesterday just thinking about it." After Wang Yu and Xu Fufang said this, the scene in Munich reappeared in Li Fanyu's mind.
Although only three years have passed, so many things have happened in the past three years. Thinking about it now makes Li Fanyu feel as if a world has passed, and as if things only happened yesterday.
In three years, I went from a poor student with nothing to where I am today. Zhengxin also started from scratch until it became a behemoth with fixed assets exceeding 150 billion and total assets exceeding 200 billion.
Among the five people who went to Germany together, and the related people. Professor Zhang has now become a big boss in the education and automobile industry. In addition to presiding over the training of Zhengxin senior technicians, he also leads the Zhengxin R&D Center. Basically, every time Tiancheng University of Technology communicates with other universities at home and abroad, it has to invite him to come over to help.
The three academic masters have also grown from technical geeks to senior engineers who can lead their own way.
Cheng Ke has grown from a middle school girl to a person who can lead a research and development team to fight against projects internally, lead a convoy to kill everyone outside, and is very good at fighting battle royale... A sick girl.
Myself, let alone that.
His eyes were blurry for a while, then he came to his senses and smiled at the three of them, "Okay, let's work harder. Now the pure electric car market has changed, and I8 must be completed as soon as possible. You can go there later Tell the team and ask them to speed up. But don’t worry about it for a while. Let’s go out to get together tomorrow. We will start to catch up on the progress! ”
"Okay!" After hearing Li Fanyu say that he wanted to treat a guest, the three top students cheered.
