Late at night, Baoshan Base.

"Mr. Luo has been in the office all day long, right?"

"No, when I brought him lunch, I saw him closing his eyes and resting, looking frowning, as if thinking. When I delivered him supper, I saw him writing formulas quickly in his notebook."

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

"Really or not?"

"Of course it's true. You haven't seen Mr. Luo in the past, most of the project departments below. Now he has already come on stage in person, keep writing complex formulas that I can't understand, and drawing a lot of circuit design drawings."

Several employees from the administrative department were whispering, talking about the changes in Luo Jia’s recent days.

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

Luo Jia wants to eat something and find the administrative department. He wants to print some documents and send a few express delivery, but he still needs to find the administrative department. So they are very clear about Luo Jia’s recent changes.

In the past, Luo Jia was like an inspector. Today he went to this project team to take a look and led everyone to think about ideas on how to overcome difficulties. Tomorrow he went to another project team to listen to their work progress.

When he encountered difficulties, he convened a brainstorming team to hold a meeting.

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

Unlike other people's way of working, Luo Jia needs to be absolutely quiet because when designing a plan, he has to constantly query information, and the information is in his mind.

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

What he is currently trying to solve is the consistent problem of lithium battery backend, that is, large-scale electronic control systems.

This thing is one of the lifebloods of electric cars and is even more important than battery packs.

In the past few days, Luo Jia has worked at least sixteen hours a day. In addition to thinking in the office, she is sleeping in the meditation center. The only entertainment is to call parents far away in Russia and ask about their travel situation.

Despite Luo Jia's repeated instructions, Comrade Luo Ning still had something to do.

The day after arriving in Vladivostok, Comrade Luo Ning fought with the Russians.

When he learned that the Russian name of Vladivostok in Vladivostok, which means conquering the East, and erecting a sculpture on the beach to point to the land of China, he seemed very unhappy and glared at the local tour guide fiercely.

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

Comrade Luo Ning said that Vladivostok, Hailanpao, and Lake Baikal were all robbed of our China. From 1926 to 1937, you had large-scale anti-China and killed nearly 200,000 Chinese. The account will be settled sooner or later!

The Russian tour guide became anxious on the spot, and the two of them fucked together 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 bottle of wine. The two of them were beaten so fierce that the battle was shocked, which scared Luo Jia's mother.

Fortunately, in addition to arranging local pickups, the travel agency also arranged for a full-time accompanying and a driver, and they quickly persuaded the person to leave.

It is said that it is so unpleasant, Comrade Luo Ning will go home quickly.

As a result, Comrade Luo Ning said he would not leave anything and kept yelling that this was our land, so why should I leave?

There was no choice but to send Comrade Luo Ning and Luo Jia's mother to Lake Baikal overnight, afraid that local snake tour guides would find an opportunity to retaliate, and urgently arranged two large-sleeved and round bodyguards among Comrade Luo Ning's accompanying staff.

When Luo Jia and Comrade Luo Ning were on the phone, he was not finished yet, and he was clamoring to meet again next time, so he must be beautiful.

Anyway, Comrade Luo Ning's trip to Russia began in this vigorous atmosphere.

Luo Jia can't do anything to his father. He has a straightforward personality all his life and hates evil, so he has to repeatedly tell him and his mother to be safe.

Shenzhen Stock Exchange, BYD Group.

It is rumored that major battery factories and Luo Jia have already had a stumble, but in fact it is just an illusion.

After getting the diaphragm and machines of Xingchen Technology, major battery factories have been working overtime to rush to make the first batch of products.

On May 5, the first batch of 18650 high-capacity batteries were officially launched, and then they conducted consistency testing on this batch of products.

What is consistency detection?

It means to detect whether all batteries have the same performance, and the detection process is extremely complicated and requires hundreds of tests.

From physical characteristics to chemical characteristics, from internal resistance to voltage, from electrolyte injection amount to the width and density of the electrode sheet, from charging curve to discharge curve.

All in all, this is a super complex project.

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

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

If there are 3.6 drops and 3.8 drops, there will be big problems in the end.

This is the strict standard for power lithium batteries. All lithium batteries, whether ten thousand or 100 million, must be consistent, and the error rate must be strictly controlled.

After all, power batteries are used for electric vehicles. There are 7,000 or even tens of thousands of batteries on an electric vehicle. It is necessary to ensure that no problems occur in each battery.

People who don’t understand this industry always think that batteries are just, how difficult can they 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, and even Panasonic, the world's number one, cannot do it.

Tesla, which uses Panasonic's top-notch battery, cannot be said to be unadvanced and the price is also very high.

But even Tesla will have spontaneous combustion.

The fundamental reason is that the front and back end electronic controls are not perfect. After using them for a period of time, some batteries age too quickly, resulting in catastrophic consequences.

BYD's engineering team repeatedly tested the first batch of offline batteries, and then placed the test report on the desk of the big boss Mr. Wang.

After reading it, Mr. Wang was stunned!

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

Mr. Wang was stunned, took off his glasses, quickly wiped them with the glasses cloth, and then picked up the report again and read it 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 next to him, "All 100,000 batteries are the same, I'm not wrong, right?"

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

Boom ~

Mr. Wang's head exploded directly. When Luo Jia sold the machine and the diaphragm to BYD that day, he did not mention consistency.

Mr. Wang felt that everyone's level should be similar. There are seven or eight products that do not meet the standards in 10,000, which are also allowed by the industry, so I didn't ask too much.

At this moment, he realized that the defective rate of batteries made with Xingchen Technology's machines was zero in 100,000! There were no defective products at all!

Liao Anhai said in a deep voice, "Mr. Wang, this time the problem is big. People in this industry are very clear. The so-called inferior products are like students who have taken 50% of the exam. But in such a big class, not only are there 50% of the exam, but also 60% of the exam and 80% of the exam. Anyway, as long as they are above 60% of the exam, we are considered passing."

"But all the products made by Xingchen Technology are 100 points! This is no longer an exam, but a machine answering question! Our engineering department feels that the test results are completely incredible, and I really don't know how they did it!"

"Damn it!"

Mr. Wang rarely swears. He is a master's degree from the Nonferrous Metals Research Institute and a senior intellectual among businessmen, so he knows too well how terrible the technology of Star Technology is.

Have a perfectly consistent lithium battery?

What is the situation!

To be honest, he was a little scared now. The problem that even Panasonic could not overcome was solved by Star Technology in one fell swoop?

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

“Subscribe to the air ticket now!”

Mr. Wang stood up from his seat, his face flushed and said to the secretary, "I want to go to Shanghai."

The manufacturer who has bought diaphragm and machine from Xingchen Technology, their boss came to Shanghai Capital at the same time, because they were shocked by the test results.

I thought Xingchen Technology solved the battery density problem, but who would have thought that they also solved the consistency, the most terrifying problem!

From Mr. Wang of BYD to Mr. Huang of CATL, these lithium battery tycoons entered Luo Jia's office with an anxious look on their faces.

After hearing their words, Luo Jia smiled and scratched her head, "I think I've said this question?"

Mr. Wang waved his hand quickly, "I didn't say it, I remember it very clearly. I knew you had even solved the consistency problem, would we come here overnight?"

Mr. Huang from CATL also said, "Yes, that day we all thought that you had a battery technology that was one-sixth of a density higher than Panasonic. Now it seems that your technology is not only powerful, but it is simply amazing!"

Luo Jia recalled, "You remembered it wrong. 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 stunned. A technological revolution such an important relationship was actually mentioned by Luo Jia and did not take it as a key point!

What is this called saying?

You should know that for the lithium battery industry, consistency problem exceeds density problem.

After all, a lower density will not kill people, and consistency problems will cause vehicles to burn or even explode, which will cause death.

"We solved it through the mold temperature machine," said Luo Jia. "I don't want to tell you the specific technical details, but our mold temperature machine has added three new indicators to the traditional four technical indicators."

"Anyway, what I sell to you is not just a machine, but a complete set of solutions. If you don't use our mold temperature machine and change to other manufacturers' machines, don't look for me if you have any problems."

So that's how it is!

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

Luo Jia did not have any problem with the mold temperature machine, but secretly sold the mold temperature machine to BYD and others.

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

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

Just as everyone was ecstatic and expressed their intention to expand production immediately. When the lithium battery industry was making a big move, An Ran suddenly rushed in.

He didn't even have time to say hello to Luo Jia, but turned on the TV and adjusted to the news channel.

"It's explode!"
Chapter completed!
