After Luo Jia sent his partner away, An Ran anxiously asked why he predicted that the Samsung battery would have an accident, which felt amazing.

Enron's question also attracted the attention of others, and they quickly surrounded Luo Jia in the middle, and he vowed not to give up if he didn't tell the truth.

"I'm not a wizard, so I don't have the power of an unpredictable prophet." Luo Jia smiled and said, "Let's go, go to my office, and I'll explain it to you." ”

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

Luo Jia spread out a few blank sheets of paper on her desk and sketched them with a pencil.

They are the structural diagram of lithium cobalt oxide battery, the discharge characteristic curve, the charging characteristic curve, and the structural diagram of the existing charging pile, the power time-sharing diagram and so on.

Although the stick figure is crooked, everyone can still understand Luo Jia's general meaning.

"Every design looks fine, but when combined, it creates a big problem, and I don't see it in the solutions announced by Samsung and LG, and they plan for it, so it's likely that they underestimated how damaging it is." Luo Jia said.

An Ran and the others were lying on the table to study, they were also one of the strongest brains in the company, and even on this earth, if Luo Jia told them the answer directly, it would not be interesting, and it would be more enjoyable if they could think of it.

Luo Jia sat on the sofa next to her, made a cup of coffee, and continued to close her eyes and meditate.

It's completely different from the early days of the business, the pressure is getting bigger and bigger, the brutal reality is like a race, surrounded by Bolt-level opponents, and even Bell Labs has gone down in person.

So Luo Jia also has to go all out, he spends a lot of time reading and researching every day.

As the leader of the tough guy group, his job is like drawing a blueprint, making a precise top-level design, and then handing over the specific details to his employees, turning the blueprint into reality step by step.

This is a very important job, after all, the helmsman is the one who sails the sea, and if the helmsman is crooked, the ship will sail directly to the Mariana Trench.

Only ten minutes later, Luo Jia heard An Ran exclaim.

is worthy of being a top genius, An Ran was able to understand Luo Jia's meaning so quickly, which made Luo Jia a little unexpected.

The fountain pen quickly calculated on the white paper, and finally got a very complex string of data, which he pointed to and said to Luo Jia, "The explosion is due to the thickening of the electrolyte interface!" ”

Luo Jia nodded, smiling, "You go on." ”

An Ran said in a fast voice: "Lithium cobalt oxide battery has the highest capacity among the six lithium battery systems, but it has a flaw, that is, service life. ”

"The anode of the lithium cobalt oxide structure is constructed in layers. During discharge, lithium ions move from the positive electrode to the negative electrode; When charging, the opposite is true, and the flow goes from the negative to the positive. ”

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

"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 increased, and the problem of anode lithium plating in the fast charging process will be magnified by geometric multiples, and when the critical point is broken, the problem of anode lithium plating will cause the problem of SEI thickening."

"The structure of lithium cobalt oxide is just layered, and when the SEI thickens to a certain extent, it will bring about an increase in internal pressure, which will make the lithium battery module expand during the charging process."

After An Ran finished his conclusion, everyone applauded at the same time, his thinking was clear, concise and clear, and he was worthy of a genius who got a double doctorate at the age of twenty-three.

Luo Jia is also very happy, assuming that he gets the extraterrestrial inheritance safely, this guy will definitely do a better job than himself, but unfortunately there is no such option in this world.

Luo Jia and An Ran carried out rapid calculations on the calculation paper, watching the two of them move their pens like flying, and it was definitely a pleasure to use the pen and brain to calculate those things that would have required powerful scientific algorithms.

Everyone shook their heads, people are more popular than people, it's really incomparable.

Luo Jia and An Ran are like two biological computers, their thinking speed is too fast, if the brainstorming team is composed of a group of monsters, they are the two most murderous among them.

The time is not big, the results are out, the calculation conclusions of the two people are completely consistent, the SEI thickening problem, will only occur in the process of high-power and high-density rapid charging and discharging, in addition, the design of Samsung and LG is actually perfect.

The collapse of an anthill is a real example of this.

With the explosion in the direction of Ulsan, Samsung and LG, and even the future of the entire South Korea, were all blown to pieces.

The others applauded enthusiastically, cheering up Luo Jia and An Ran's genius performances.

Luo Jia put the fountain pen on the table and shrugged his shoulders, "Actually, there is also an element of luck in this, although I thought that their design might have problems, but I didn't expect that it would explode so badly." ”

Everyone nodded one after another, what science needs is not rigor, but absolute rigor, and everything you do in the future will have to be calculated a few more times.

"That's all for today." Luo Jia said, "lithium battery on the car, it is imperative, there is not much time left for us, although the front-end electronic control has been solved, but we also have to solve the back-end electronic control, that is also a huge problem." ”

......

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

The front-end electronic control is how to manufacture high-quality and highly consistent batteries, while the back-end electronic control is how to carry out the scientific management of tens of thousands of batteries.

It is not enough to manage tens of thousands of batteries at a time, but also to study how the battery pack works with the transmission system to improve the efficiency of discharge and charging, and output the maximum power with the least energy consumption.

How to make sure that the temperature of each battery is consistent, in case one or two batteries in the battery pack decay too quickly, how to repair it, how to repair it if it can't be completed, how to shield the damaged battery.

Anyway, in general, the back-end electronic control is also related to the lifeblood of vehicle safety, in addition to the mileage, vehicle maintenance costs and so on.

Luo Jia and the entire hardware army are painful and happy, as a new enterprise that has just been established for a year, it lacks experience accumulation in the huge and profound automotive industry, although the introduction of talents has been ongoing, but in the short term, it is still difficult to make up for the lack of experience.

Luo Jia maintains a sixteen-hour work intensity, and her office is filled with coffee and Red Bull, in addition to a large number of calculus papers and design sketches.

Although he is implementing a paperless office, he is still a little unaccustomed to it, preferring to trust the pencil and scratch paper in his hand.

After two more busy days, Xu Chunbiao finally came back from South Korea.

He didn't go alone, but he brought with him eight brothers from the guard.

Every employee of the security department is carefully screened by Luo Jia with the eye of the sky, they have retired from the field army or reconnaissance unit, and their history is innocent, and their character and morality are impeccable.

The security guards are not guarded, they have a special office, and there are one hundred and seventy-three monitors in the office, which can clearly observe the entire base.

They also patrol the company, but they are dressed like everyone else, but they are superb, constantly looking at dark corners for suspicious infiltrators.

Anyway, Xu Chunbiao and the more than 50 retired soldiers in the security department are all the defense forces of Xingchen Technology now.

They are divided into five shifts to ensure that there are about ten people on duty in the company at all times, the salary belongs to the domestic super-first-class level, overtime and additional overtime pay, food and accommodation are all inclusive of the company.

Huaxia is extremely safe in the world.

Luo Jia feels that these defense forces are enough at present, and it is not a Mexico with a rain of bullets, there is no need to recruit a large group of macho men in black suits and sunglasses like in the movie, if there is really anything, it is most reliable to play 110.

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

Xu Chunbiao looked a little frustrated, he did what Luo Jia said, and after arriving in South Korea, he immediately divided into three ways and went to the three major test sites in South Korea, and used a telephoto lens to shoot every move at the test site.

This is not an uncommon thing, many car magazines and websites, will send people to keep an eye on the test site, once there is a new model test on the Hyundai side, they can take first-hand spy photos, put them in magazines and websites, for the majority of car enthusiasts to read.

Luo Jia once read in automobile magazines that even Alaska, Iceland, Norway, those test sites that specialize in testing the performance of cars in extreme cold conditions, there are also car paparazzi who are not afraid of the cold and stay for a long time.

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

In short, Xu Chunbiao, according to Luo Jia's arrangement, mixed with those car paparazzi and gathered on a hillside, waiting to shoot the scene of the explosion of the modern car.

However, due to the problem of shooting angles, 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, I knew that they were so enthusiastic, so I wouldn't let Xu Chunbiao run this trip in vain.

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

The brothers who went to South Korea on this business trip, all took a holiday, after all, they had no credit and hard work, for a whole week, three people took turns on duty, aimed at the test site with a telephoto, and spent a lot of energy and physical strength for a moment of lax observation.

The Administration Department has recently set up a travel department, and due to the increasing scale of Xingchen Technology, it is no longer possible for the whole company to travel as it did in the early days of the business.

The role of the travel office is to help employees arrange their holidays reasonably and take advantage of the free travel benefits provided by the company.

Luo Jia insisted on letting everyone go out and walk more, after all, only by experiencing the world in person can we better understand the opponent.

All employees travel twice a year at public expense, regardless of destination, and can find a travel office wherever they want to go, so that they can arrange visas and accommodation on their behalf, which is the only one among domestic high-tech enterprises.

Time flies, Luo Jia continues to think hard in order to get the back-end electronic control, and at the same time, the three major car manufacturers have started lithium battery on the car plan.

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 electronic control requirements, which require a new, higher-level electronic control system.

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

Because it is only the first generation of Xingchen Technology's products, the battery life of 600 kilometers has just started, and there will be higher energy batteries in the future.

Even Xingchen Technology has not done high-energy electronic control, and it is even more difficult for the three major factories to turn their electrical engineers around.

Another problem is the anger of domestic giants.

They were shocked to see that Luo Jia gave the world's best lithium battery to BYD, Great Wall, and Geely, but did not give it to them.
