For things like speeches and meetings, Luo Jia is now familiar with it.

He walked up to the stage with a relaxed look and made some polite remarks such as a welcome speech.

Then he changed his words, "I would like to invite experts from major automobile companies to come to the stage to introduce to us the electronic control system that you are currently using." ”

As a result, the technical teams of major car manufacturers took the stage to speak.

The electrical engineer of a car factory proudly announced that the electronic control system they are using now comes from Neon Denso, which is specially designed by Denso for their factory, how good is the performance, how wide the dynamic management range is, what standard is the durability and so on.

In addition, there are car factories with Continental products, Bosch products, or Freescale, Toshiba.

The electronic control system produced by domestic manufacturers is not unused, but engineers have said that domestic electronic control is mainly used in low-end models to reduce costs.

After listening to their speeches, Old Man Ouyang furrowed his eyebrows.

It's not that he doesn't know the current status quo of the electronic control industry, but it is still a little desperate to hear that domestic automobile companies have reported so many foreign manufacturers in front of him.

Denso, Continental, Bosch, and the three giants of auto parts are naturally extremely powerful, but I didn't expect that Lianming Electric House and UQM have also entered the supply chain of major car companies.

In the electronic control system used by domestic car factories, there was a wonderful scene of a hundred flowers blooming by overseas manufacturers, which is really a result that makes people laugh and cry.

At the end of the speeches of the major automobile manufacturers, as soon as Luo Jia came to the stage, he directly pointed out unceremoniously, "Actually, it is not necessarily how much Neon Denso attaches importance to it and how eager it is to serve you, but because the major shareholder of Denso is Toyota, and you have cooperated with Toyota for so many years and helped Toyota make so much money. ”

This is quite faceless, but it is true, the company named by Luo Jia sells millions of Toyota cars every year, and they and Toyota make a lot of money.

After a pause, Luo Jia said, "Bosch is also based on the same reason, because everyone here has also sold a lot of Volkswagen, Mercedes-Benz, BMW. ”

Hearing this, Old Man Ouyang was slightly stunned, he seemed to feel something from Luo Jia's words, could it be

Luo Jia began to write quickly on the whiteboard, "Toyota, Honda, Hitachi, Bosch, Ford, General Motors, Meidensha, Toshiba, UQM, ACA, Freescale, MM, Yaskawa." ”

"The current field of electronic control systems is the world of the above 14 giants, and I will not list Denso and the like, because they are Toyota's vest factories, 14 international giants, accounting for more than 90% of the global share."

"And China has Inovance, Blue Ocean Huateng, Hudu Electric Drive, Dajun, Songzheng, Wuzhoulong, CSR Times, these seven major manufacturers of electronic control systems."

"The situation has just been explained very clearly, international giants do high-end, and these factories in China are mainly low-end."

"The electronic control market is very large, even if you buy a 3,000 yuan electric bicycle, there will be a small electronic control box inside, although the grade difference is a little far, but it is indeed a kind of electronic control, and there are elderly electric vehicles running around on the street, which is also electronically controlled."

"The automotive electronic control mainly refers to the VCU, that is, the two categories under the vehicle management system, the PCU motor management system, and the BMS battery management system."

"I invite you here today mainly to explain the research we have done in the PCU system and BMS system, so as to facilitate more in-depth cooperation in the future."

Luo Jia's opening remarks ended, and he began to give a more in-depth technical explanation to the experts present.

At the beginning of this lecture, the scene immediately became silent, because Luo Jia and An Ran had stayed for a long time and learned his problem of speaking quickly.

Especially when talking about technology, Luo Jia seems to enter a state of selflessness to block all the interference around her.

As his emotions are mobilized, he will become more and more excited, and whoever does not listen carefully will not understand.

The ink pen quickly drew the design on the whiteboard, Luo Jia started from the water cooling system of the battery module, why the parallel structure is used instead of the series structure, the efficiency data of the coolant, the new explosion-proof valve that has been patented, and even the glue that fixes the insulating board is also re-developed by Xingchen Technology.

Everyone is really dumbfounded, what is the situation?

Xingchen Technology even makes its own glue?

But think about it carefully, they have a subsidiary called Xingchen Chemical, which can make the world's only seventh-grade modified fully synthetic photoresist, and it seems to be quite normal to develop special glues by themselves.

This is no longer an improvement of the BMS system, but they have thrown away the past and redesigned a whole set!

Then Luo Jia began to talk about communication again, using dual backup measures to communicate with BMU through SPI bus.

It turns out that BUM, that is, the general controller, is also independently designed by Xingchen Technology!

If you think about it carefully, Xingchen Technology has a semiconductor design department, and the semiconductor design department led by Fang Yuanchu has developed a perverted technology such as quadruple drive display IC, and they do have the ability to design BUM by themselves.

"Is this a technical explanation? They're flexing their muscles, aren't they? ”

"me, they've also designed a pre-charged contactor!"

"Wouldn't it, three MCUs? Is this the rhythm of going to heaven safely? Tesla only used two sets. ”

"They also designed their own BMB monitoring module!"

At the scene, these engineers from major automobile factories finally understood why Xingchen Technology was called a tough guy group.

One is because they do have strength.

Second, these guys are too upright, okay!

They are not satisfied with the electronic control system in the past, what should they do if they are not satisfied?

Roll up your sleeves and do it yourself, of course!

This group of madmen turned the complex electronic control system upside down, rebuilt all the furnaces from the inside out, made it unrecognizable, and rebranded it with Xingchen Technology!

"Look at Professor Ouyang."

The engineers saw that Professor Ouyang was lying on the table taking notes, all of whom were over seventy years old, but at this moment they looked excited and struggling to write.

Just when everyone was excited, Luo Jia suddenly stopped speaking, threw the fountain pen on the table, and said with a smile, "It's almost one o'clock before you know it, you haven't had lunch yet, let's go to our canteen and eat something." ”

Only then did everyone realize that their stomachs had indeed begun to growl, and although they were still unsatisfied, they still had to eat.

So they went to the canteen of Xingchen Technology to have lunch, and were immediately shocked by the luxury canteen.

A combination of Chinese and Western, eight major cuisines, everything.

Look at the canteen of Xingchen Technology, and then think about the big pot dishes of your own company, don't talk about it, it's all tears when you talk too much.

Luo Jia and Professor Ouyang sat at the same table, the old man was old, and the amount of food was very small.

He was not interested in eating, but he was deeply fascinated by what Luo Jia said today, and if he didn't understand something, he asked Luo Jia and An Ran to explain it again, and then he added his notes while listening.

"I didn't expect that even the motor control chip was designed by yourself." Closing the note, Professor Ouyang said with emotion: "Infineon has been dominating electronic control chips for many years, and I really hope you can break their monopoly." ”

Luo Jia hurriedly said, "It's not me, but the credit of our entire team, and Infineon doesn't actually dominate the electronic control chip, STMicroelectronics, Texas Instruments, Freescale, they are also doing it, but at present, Infineon is doing the best." ”

Luo Jia then made an analysis of the electronic control chip market, what is the proportion of Infineon's AURIX, how much is the market share of Texas Instruments' 28335 and so on.

Professor Ouyang's eyes lit up suddenly, but he didn't expect Luo Jia to understand not only technology, but also the market.

This is the characteristic of Luo Jia, who likes to spend a lot of time researching competitors in various fields and doing in-depth market research.

After lunch and a short break, the afternoon seminar continued.

After Luo Jia finished speaking, the ministers of various project departments came to the stage to answer various questions.

At this point, even Professor Ouyang can see it, what kind of seminar, this is simply Xingchen Technology to show off its muscles!

Enron, a double Ph.D. from MIT.

Dongning Zhang, Ph.D. in Chemistry, University of Berlin, is the highest credit holder in history.

Ling Feng, a former colleague of Professor Ouyang, is the top student in the college entrance examination and a well-known electrical expert at Tsinghua University.

Ji Ming, Ph.D. in Materials Science, University of Cambridge, has presided over the Cambridge Nanomaterials Laboratory.

Zhang Yuechuan, Ph.D. in optics from the University of Colorado, former technical director of Da Liguang, don't look at the University of Colorado It seems that it is not well-known, but their optical engineering and Massachusetts are tied for the first place in the world.

The hardware corps is currently nearly 1,300 people, and doctors account for one-third, of which more than sixty percent are elites who have returned from overseas.

And the members who can enter the brainstorming team are the best among such a large number of doctors, and they report their identities and mentors, which is simply scared to death.

The people sent by the major corporate giants are not weak, they are all electrical engineering directors, or directly technical directors and so on.

But they are really weak in front of such a strong lineup.

No matter how Xingchen Technology chooses in business, at least their technology is really good, and they have independently developed a complete set of electronic control systems, and even the chips are designed by themselves!

The electronic control system is not yet complete, and once it is completed, it will definitely be an uproar in the field, with a very high level of technology, designed for the next generation of electric vehicles.

Before I knew it, it was already dark, Luo Jia announced the end of the seminar, and also sent souvenirs to everyone, a set of home astronomical telescopes jointly launched by Phoenix Optics and Xingchen Technology Optics Department.

Although it cannot be compared with a professional astronomical scope, it is very suitable for primary school or middle school students, only more than 2,000 yuan a piece, and the performance is comparable to a high-end product of tens of thousands of yuan.

After dinner, Luo Jia sent them to the hotel.

Professor Ouyang said to Luo Jia, "Originally, there was one more thing I wanted to talk to you about, but I can't do it today, I'm really tired, so let's go to the hotel tomorrow to find me, I have something to say to you." ”

Luo Jia nodded and agreed, and made an appointment with him to meet tomorrow.
