Technological Hegemony

Late at night, Baoshan base.

"Boss Luo has been in the office all day, right?"

"That's right, when I brought him lunch, I saw him closing his eyes and resting his mind, his brows were tightly furrowed, as if he was thinking. When I brought him dinner, I saw him writing formulas quickly in his notebook." .”

"It's not easy. After all, after the hardware department has finished the battery, the next step is the car project."

"real or fake?"

"Of course it's true. Didn't you see that Mr. Luo used to point out the project department below, but now he's on the stage in person, writing complex formulas that I can't understand, and drawing a lot of circuit design diagrams."

Several employees of the administration department were whispering about Luo Jia's changes in recent days.

In Star Technology, the administrative department is equivalent to the function of the logistics headquarters.

Luo Jia wanted something to eat and went to the administration department, wanted to print some documents, send a few couriers, or go to the administration department, so they were very aware of Luo Jia's recent changes.

In the past, Luo Jia was like an inspector. Today he went to this project team to see and lead everyone to think of ideas on how to overcome difficulties, and tomorrow he went to other project teams to hear their work progress.

When he encountered difficulties, he called a meeting of the brainstorming group.

But now, Luo Jia locked herself in the office and didn't come out all day, as if she was trying her best to solve some problem.

Different from other people's way of working, Luo Jia needs to be absolutely quiet, because when he is designing a plan, he has to constantly search for information, and the information is in his brain.

This is a bit of a communication between heaven and man. On the one hand, it is to extract useful parts from the massive data, and on the other hand, it is necessary to integrate these technical materials into a feasible solution.

What he is currently trying to solve is the back-end consistency problem of lithium batteries, that is, large-scale electronic control systems.

This thing is one of the lifeblood of electric vehicles, even more important than the battery pack.

In the past few days, Luo Jia worked at least 16 hours a day. Apart from thinking in the office, he slept in the meditation center. The only entertainment was to call his parents in Russia and ask them about their travels.

Despite Luo Jiaqian's exhortations, Comrade Luo Ning made trouble.

On the second day after arriving in Vladivostok,

Comrade Ronin fought with the Russians.

When he learned that the Russian name of Vladivostok is Vladivostok, which means to conquer the East, and there is a sculpture on the seashore pointing to the land of China, he was very unhappy and stared at the local The tour guide has two eyes.

The local tour guide is Russian and can speak. He asked Comrade Luo Ning, what are you looking at me for?

Comrade Luo Ning said that Vladivostok, Hailanpao, and Lake Baikal all robbed us of China. From 1926 to 1937, you massacred Chinese and killed nearly 200,000 Chinese. This account will be settled sooner or later!

The Russian tour guide became anxious on the spot, and the two of them went straight to each other without saying a word.

Comrade Luo Ning was punched in the face, and the Russian tour guide was opened by Comrade Luo Ning with a wine bottle. The two fought fiercely, and Luo Jia's mother was shocked.

Fortunately, in addition to arranging the ground pick-up, the travel agency also arranged a full-time escort and a driver, and they quickly persuaded him to leave.

It is supposed to be so unpleasant, Comrade Luo Ning should go home quickly.

As a result, Comrade Luo Ning didn't say anything and kept yelling that this is our land, so why let me go?

There was no other way, the travel agency had no choice but to send Comrade Luo Ning and Luo Jia’s mother to Lake Baikal overnight, fearing that the land snake tour guide would find an opportunity to retaliate, and urgently arranged two bodyguards with big waists among Comrade Luo Ning’s entourage.

When Luo Jia was on the phone with Comrade Luo Ning, he was still in the middle of the conversation, yelling that we would meet again next time, and that the Russian guy must be nice.

Anyway, Comrade Luo Ning's trip to Russia started in such a vigorous atmosphere.

Luo Jia couldn't do anything about his father. He had an upright personality all his life and was jealous of evil, so he had to repeatedly ask him and his mother to pay attention to safety.

Shenzhen, BYD Group.

It is widely rumored that the major battery factories and Luo Jia have fallen out, but in fact that is just an illusion.

After receiving the diaphragm and machines from Star Technology, major battery factories have been working overtime to produce the first batch of products.

On May 5th, the first batch of 18650 high-capacity batteries officially rolled off the production line, and then they conducted a consistency test on this batch of products.

What is consistency detection?

It is to test whether all batteries have the same performance, and the testing process is extremely complicated, requiring hundreds of tests.

From physical characteristics to chemical characteristics, from internal resistance to voltage, from electrolyte injection amount to pole piece width and density, from charging curve to discharging curve.

All in all, this is a super complex project.

The purpose of the consistency test is to ensure that all batteries are exactly the same.

After 10,000 batteries are fully charged and discharged 100 times, the capacity drops by 3.7%, so all of them must be 3.7%.

If there is a drop of 3.6 or 3.8, there will be a big problem in the end.

This is the harsh standard for power lithium batteries. All lithium batteries, no matter 10,000 or 100 million, must all be consistent, and the error rate must be strictly controlled.

After all, power batteries are used for electric vehicles. There are usually seven to eight thousand or even tens of thousands of batteries in an electric vehicle. It is necessary to ensure that each battery will not go wrong.

People who don't know this industry will always think that it's just a battery, how difficult can it be?

However, in fact, the lithium battery industry is really difficult and belongs to the absolute top technology.

So far, no manufacturer in the world can completely solve the problem of battery consistency, even the world's number one Panasonic can't do it.

Tesla, which uses Panasonic's top batteries, cannot be said to be advanced, and the price is also very high.

But even Teslas can spontaneously combust.

The fundamental reason is that the front and rear electronic controls are not perfect. After a period of use, some batteries age too quickly, which leads to catastrophic consequences.

BYD's engineering team repeatedly tested the first batch of off-line batteries, and then put the test report on the desk of the boss, Mr. Wang.

After Mr. Wang finished reading it, he was stunned!

According to the test report, the total number of the first batch of batteries is 100,000, and all the performances are exactly the same!

Mr. Wang was taken aback for a moment, took off his glasses, wiped them quickly with a cloth for glasses, then picked up the report again, and started to read from the first page.

After a long time, he put the report on the table, took a deep breath, and said to Liao Anhai, the chief engineer who had been waiting beside him, "The 100,000 batteries are all consistent, am I right?"

Liao Anhai nodded vigorously, "No, it's really 100% consistent. We've never seen this kind of situation before."

Boom~

Mr. Wang's head exploded immediately. When Luo Jia sold the machine and diaphragm to BYD that day, he didn't mention the consistency.

Mr. Wang felt that everyone's level should be about the same. There are seven or eight substandard products out of 10,000, which are allowed by the industry, so he didn't ask too much.

At this moment, he discovered that the defective rate of batteries made by Xingchen Technology's machines is actually zero among 100,000 batteries! There are no defective products at all!

Liao Anhai said in a deep voice, "Mr. Wang, this time there is a big problem. Those of us in this industry know very well that the so-called inferior products are like students who have scored 50 points in the exam. Those with fifty points, and those with sixty points and eighty points, anyway, as long as they are higher than sixty points, we will consider them as passing."

"But the products made by Xingchen Technology are all 100%! This is no longer a test, but a machine answering the question! Our engineering department thinks that the test results are completely incredible. I really don't know how they do it!"

"Damn it!"

It is rare for Mr. Wang to swear a bad word. He is a master of the Nonferrous Metal Research Institute and a senior intellectual among businessmen, so he is too aware of the terrible technology of Xingchen Technology.

Lithium batteries with perfect consistency?

what is happening!

To be honest, he is a little frightened now, the problem that even Panasonic failed to overcome, Star Technology actually solved it in one fell swoop?

If I had known this was the result, Mr. Wang would not have cheered and applauded when he was in Changzhou that day. He should have worshiped him!

"Book your flight now!"

President Wang suddenly stood up from his seat, his face flushed, and he said to the secretary, "I'm going to Shanghai."

The bosses of manufacturers who have bought diaphragms and machines from Xingchen Technology came to Shanghai by coincidence, because they were all shocked by the test results.

Thinking that Star Technology has solved the problem of battery density, who would have thought that they also solved the most terrible problem of consistency!

From Mr. Wang of BYD to Mr. Huang of Ningde era, these lithium battery tycoons entered Luo Jia's office one after another, looking eager.

After hearing what they said, Luo Jia scratched his head with a smile, "I seem to have mentioned this question before?"

Mr. Wang quickly waved his hand, "I didn't say anything, I remember it very clearly, if I knew that you had even solved the consistency problem, why should we rush here overnight?"

Mr. Huang from the Ningde era also said, "That's right. That day we all thought that you had developed a battery technology with a density one-sixth higher than that of Panasonic. Now it seems that your technology is not only powerful, but also a god!"

Luo Jia recalled, "You remember wrongly. I said that day that Xingchen Technology has completely opened up the lithium battery technology chain, and this technology chain obviously includes consistency issues."

Everyone was dumbfounded. The technological revolution, which is so important to emotions, was brought up by Luo Jia in one stroke, and it was not regarded as the main point!

How do you say this?

We must know that for the lithium battery industry, the consistency problem exceeds the density problem.

After all, a lower density will not kill people, but consistency problems will cause the vehicle to burn or even explode, which will kill people.

"We solved it through the mold temperature controller." Luo Jia said, "It's not convenient for me to tell you the specific technical details, but our mold temperature controller has added three new indicators in addition to the traditional four technical indicators."

"In short, what I sell to you is not just a machine, but a complete set of solutions. If you don't use our mold temperature controller and replace it with another manufacturer's machine, don't come to me if you have any problems."

So this is ah!

Everyone suddenly realized that the mold temperature machine is a machine used in the coating process of lithium batteries, in order to keep the raw materials uniform and highly consistent.

Luo Jia did not mention the mold temperature machine to the public, but secretly sold the mold temperature machine to BYD and the others.

Thinking about it now, there is actually a reason why Luo Jia didn't mention the mold temperature controller.

It turns out that the mold temperature controller manufactured by Xingchen Technology is completely different from the previous products, and has undergone major technological upgrades!

Just when everyone was ecstatic and expressed that they would immediately expand production and make a big splash in the lithium battery industry, An Ran suddenly rushed in.

Before he even had time to greet Luo Jia, he turned on the TV and tuned to the news channel.

"exploded!"

"Ten minutes ago, South Korea really exploded!" An Ran shouted excitedly.
