After Luo Jia sent her partner away, An Ran asked anxiously why he predicted that there would be an accident in Samsung batteries, which felt very magical.

An Ran's question also attracted the attention of others. They quickly surrounded Luo Jia in the middle, as if he would not give up until he told the truth.

"I'm not a wizard, so I can't have the ability to predict the uncertainty." Luo Jia said with a smile, "Let's go, go to my office, I'll explain it to you."

So, the group returned to Luo Jia's office.

Luo Jia spread a few pieces of white paper on his desk and used a pencil to draw sketches on it.

They are the structural diagram of lithium cobalt oxide batteries, discharge characteristic curves, charging characteristic curves, and structural diagrams of existing charging piles, power time-sharing diagrams, etc.

Although the simple strokes are crooked, everyone can understand Luo Jia's general meaning.

"Every design looks like no problem, but when combined together, it will create a big and small problem. I didn't see the solution announced by Samsung and LG. They made plans for this problem, so they probably underestimated its destructiveness." Luo Jia said.

An Ran and others lay on the table to study. They were also one of the most powerful brains in the company, and even on the earth. If Luo Jia directly told them the answer, it would be meaningless and it would be even more satisfying if he could think of it.

Luo Jia sat on the sofa beside her, soaked a cup of coffee, and continued to close her eyes and ponder.

It is completely different from the early stage of entrepreneurship. The pressure is getting bigger and bigger. The cruel real environment is like a race. There are Bolt-level opponents around, and even Bell Labs have ended in person.

So Luo Jia also has to do his best, and he has to spend a lot of time reading and researching every day.

As the leader of the Tough Man Group, his work is like drawing a blueprint, making accurate top-level designs, and then handing over the specific details to his employees, turning the blueprint into reality step by step.

This work is very important. After all, sailing in the sea depends on the helmsman. If the helmsman is crooked, the ship will directly drive to the Mariana Trench.

After only ten minutes passed, Luo Jia exclaimed when she heard An Ran exclaim.

As a genius, An Ran could understand Luo Jia's meaning so quickly, which made Luo Jia a little unexpected.

The ink pen quickly calculated on the white paper, and finally An Ran obtained a string of very complex data. He pointed to the string of data and said to Luo Jia, "The explosion was because the electrolyte interface thickened!"

Luo Jia nodded with a smile, "You continue to say."

Anran said in a quick speech: "Lithium cobalt oxide battery has the highest capacity among the six major lithium battery systems, but it has one defect, which is its service life."

"The negative electrode of the lithium cobalt oxide structure is structured in a layered manner. During discharge, lithium ions move from the positive electrode to the negative electrode; on the contrary, the flow rate goes from the negative electrode to the positive electrode."

"In order to increase the life of lithium batteries, Samsung and LG have injected mixed materials of nickel, manganese and aluminum into the lithium battery."

"The idea of ​​increasing mixed materials and solving the life problem is not a problem in itself, but this time their design density is extremely high, which means that their charging power must also be improved accordingly. The anode lithium plating problem in the fast charging process will be amplified by geometric multiples. When the critical point is broken, the anode lithium plating problem will cause the sei thickening problem."

"The lithium cobalt oxide structure is just layered. When the SEI thickening reaches a certain level, it will increase the internal pressure and cause the lithium battery module to expand during charging."

After An Ran said his conclusion, everyone applauded at the same time, with clear ideas and conciseness. He deserves to be a genius who won a double doctorate at the age of 23.

Luo Jia was also very happy. Assuming that An Ran had obtained the alien heritage, this guy would definitely do better than himself. Unfortunately, there is no option in this world.

Luo Jia and An Ran were calculating quickly on the calculation paper, watching them use their pens to fly, and calculating the things that they originally needed powerful scientific computing programs to do with their pens and brains is definitely a pleasure.

Everyone shook their heads, it was really unparalleled to compare with people.

Luo Jia and An Ran are like two biological computers, and their thinking speed is too fast. If the brainstorming group is composed of a group of monsters, they are the two most vicious.

The time is not long, and the result is coming out. The two people's calculation conclusions are completely consistent. The problem of SEI thickening will only occur during high-power and high-density fast charging and discharging. In addition, the design of Samsung and lg is actually perfect.

The Thousand Mile Dike collapsed from an ant hole, and now it is a very real example.

With the explosion in Ulsan, Samsung, LG, and even the future of South Korea were all blown up.

The others applauded warmly, and were excited by Luo Jia and An Ran's genius performance.

Luo Jia still put the ink pen on the table and shrugged, "Actually, there is also a component of luck here. Although I thought that their design might have problems, I didn't expect that it would explode so tragically."

Everyone nodded. Science requires not rigor, but absolute rigor. Everything you do in the future requires a few more calculations.

"Let's just stop here today." Luo Jia said, "It is imperative to get on the lithium battery into the car. We don't have much time left for us. Although the front-end electronic control has been solved, we still have to solve the back-end electronic control, which is also a huge problem."

As Xingchen Technology intends to enter the automotive industry, Luo Jia also began to feel the sourness of the liver, and was tortured by the back-end electronic control system.

How does the front-end electronic control make high-quality and highly consistent batteries, while how does the back-end electronic control scientifically manage tens of thousands of batteries.

It would be fine to manage tens of thousands of batteries at a time, but we also need to study how the battery pack cooperates with the transmission system to improve the efficiency of discharge and charging, and output the maximum power with minimal energy consumption.

How to ensure that the temperature of each battery is consistent, if one or two batteries in the battery pack are decaying too fast, how to repair it, repair cannot be completed, and how to shield the damaged battery.

Anyway, in general, the rear-end electronic control is also related to the lifeblood of the entire vehicle's safety, and it is also related to the range, vehicle maintenance costs, etc.

Luo Jia and the entire hardware army are both in pain and joy. As a new company that has just been established for a year, they lack experience accumulation in the huge and profound automobile industry. Although talent introduction has been underway, it is still difficult to make up for the lack of experience in the short term.

Luo Jia maintains work intensity for sixteen hours a day, and her office is filled with coffee and Red Bull, as well as a lot of calculation paper and design sketches.

Although he is promoting paperless office work, he is still a little unaccustomed to it and is more willing to believe in the pencils and draft paper in his hand.

After two more days of busyness, Xu Chunbiao finally returned from South Korea.

He did not go there alone, and he also brought eight brothers from the security office.

Every employee of the Security Department was carefully screened by Luo Jia with the Eye of the Sky. They retired from the field troops or the reconnaissance troops, and their history is innocent, their personality and character are impeccable.

The security department does not stand guard at the doorman. They have a special office, with 173 monitors in the office, which can clearly observe the entire base.

They also patrol the company, but they dress like everyone else, but their eyes are exquisite, constantly looking at the dark corners, looking for suspicious intruders.

Anyway, Xu Chunbiao and the more than 50 retired soldiers from the Security Department are the entire defense force of Xingchen Technology now.

They are divided into five classes, ensuring that there are about ten people in the company at all times. The salary is in the top domestic level. There are additional overtime pays for overtime, and the food and accommodation company is inclusive.

China is extremely safe in the world.

Luo Jia feels that these defense forces are enough at present, and they are not Mexico with bullets. There is no need to do it, just like in the movie, to recruit a large group of men wearing black suits and sunglasses. If something really happens, it is better to hit 110.

Luo Jia asked Xu Chunbiao to sit on the sofa, then brewed two cups of black tea, and handed him a cigarette.

Xu Chunbiao seemed a little depressed. He did what Luo Jia said. After arriving in South Korea, he immediately divided his troops into three groups and went to the three major test yards in South Korea. He used a telephoto lens to shoot every move of the test yard.

This is not a rare thing. Many car magazines and websites will send people to stare at the test parking lot. Once Hyundai has a new model to test, they can take first-hand spy photos and put them on magazines and websites for car enthusiasts to read.

Luo Jia once read in a car magazine that even Alaska, Iceland, Norway, those test yards that specialize in testing cars in extreme cold conditions, there are also paparazzi who are not afraid of the cold and stay in the long term.

In addition to the media, major car manufacturers around the world also need information about their competitors' new models, and they will also send people to keep an eye on them.

In short, Xu Chunbiao, according to Luo Jia's arrangement, mingled with the car paparazzi, gathered on a hillside, waiting to film the scene of the Hyundai car explosion.

But due to the shooting angle, they didn't take anything, and they didn't know where so many pictures and videos came from, so Xu Chunbiao was very disappointed.

Luo Jia smiled. Do you still need to guess those videos and pictures? It must be the power of the authorities of various countries. If they had known that they were so enthusiastic, they would not have let Xu Chunbiao go to this trip in vain.

After comforting Xu Chunbiao, Luo Jia asked him to go back and rest.

The brothers who went to Korea on this business trip all took a vacation. After all, they had no credit and worked hard. For a whole week, three people took turns to be on duty, aiming the test yard with telephoto, and observing without slacking off for a moment, consuming a lot of energy and physical strength.

The Ministry of Administration recently established a travel office. As Xingchen Technology is getting bigger and bigger, it is no longer possible for the entire company to travel like in the early stages of its business.

The role of the travel department is to help employees arrange holidays reasonably and make good use of the free travel benefits provided by the company.

Luo Jia insists on letting everyone go out for more trips. After all, only by experiencing the world personally can we better understand our opponents.

All employees travel twice a year for public expenses, regardless of destination. You can find a traveling office wherever you want to go and ask them to arrange visas and accommodation on their behalf. Such generous conditions are also the only one among domestic high-tech enterprises.

Time flies, and Luo Jia continues to think hard to get the back-end electronic control. At the same time, the three major car manufacturers have begun plans to board lithium batteries.

At present, Luo Jia has two troubles, both of which are big troubles.

High-energy electric vehicles with a range of more than 600 kilometers have strict electrical control requirements and need to use brand new and higher-level electrical control systems.

Why is Luo Jia obsessed with the new generation of electronic control?

Because it is only the first generation of Star Technology's product, with a range of 600 kilometers just now, and higher-energy batteries will be released in the future. If the electronic control problem is not available, you must prepare for the future.

Even Xingchen Technology has not done high-energy electronic control, the three major manufacturers are even more difficult, and they are in a hurry to turn their electrical engineers around.

Another problem is the anger of domestic giants.

They were shocked to see Luo Jia give the world's best lithium battery to BYD, Great Wall and Geely, three small and medium-sized factories, but not to them.
Chapter completed!
