Chapter 931 Professional Opinion

The NEXTDOOR Park under construction still looks like a big construction. Most of the buildings have already taken shape, but that's all.

If it were our domestic construction colleagues, the construction of the park should have been completed by at least half, not 80% now. However, who says that these American construction workers are all noble workers? The efficiency is definitely not high.

Feng Yiping rarely comes here, and several bosses of the construction company personally accompany him. There are also several designers who are also dressed in suits and leather shoes even on the construction site.

"Feng, according to the current progress, we will definitely be able to complete the project on time as agreed in the contract," the construction bosses said.

Although Feng Yiping is dissatisfied with the speed of the domestic construction industry - you know, if the park is completed one day ahead of schedule, he can save a lot of rental fees, but he can't do anything about it.

American workers are like this, doing things slowly, which is their fatal flaw.

But at the same time, they all have certain professional skills and do things in a very methodical way. In addition, professional construction companies have all kinds of professional equipment, so everything on the construction site is in order.

Compared with the construction sites in China, which are bustling with people and full of enthusiasm, but the on-site management is extremely casual, the construction sites abroad have fewer people, and everything is done slowly and in a very orderly manner. They are definitely two extremes.

One is like a young person who has just entered the workplace, full of energy, willing to work, motivated, willing to treat work as a career, but not paying much attention to details, and has no experience.

The other is a veteran who has been immersed in the workplace for many years, experienced and professional, but it is difficult to mobilize his enthusiasm. He is completely a monk who does not do his job well.

But there is a good thing in the United States. The owner does not have to worry about safety.

For these construction companies, if a safety accident that causes casualties occurs, the consequences will definitely be devastating, even if they do not go bankrupt. Therefore, they are more nervous about this matter than Feng Yiping.

Feng Yiping does not have to worry about things like cutting corners. If a safety accident occurs, the construction company will still have a way out, but if it is maliciously cutting corners, once it is verified, there will be no way out.

Of course, it is not to say that there are no such builders abroad, but because the cost of doing so is very high, such things are still rare - at least less than in China.

"Thank you, everyone," in this country where everything is about contracts, Feng Yiping was dissatisfied, but it was difficult to say anything, "Please do as you please, I'll go over there to take a look."

Only one corner of the park has been completed, that is the battery laboratory of ** Straubel and Mark Tarpenning.

As soon as he said this, no one followed him. The workers on the construction site had consciously regarded the area around the independent small building as a forbidden area.

This was also Feng Yiping's first time to come to their laboratory. He clearly saw that there were traces of smoke on the specially set ventilation vents next to it. Is it really that exaggerated?

It is really that exaggerated. After swiping the access card and entering the building, Feng Yiping found that the layout of this office was very professional. The outer room was the control room with many instruments. Through the glass, you can clearly see the laboratory inside.

It seems that this glass must also be specially made, because there are really many traces left by intense reactions on the walls of the laboratory inside.

At the alloy workbench, Stella and Mark, wearing masks and gloves, and their assistants, were "stuffing" lithium batteries into a large frame.

Looking at the marks on the wall inside, Feng Yiping didn't want to go in and participate, so he called out on the loudspeaker in the control room, "Hi,"

They looked up and saw Straus and Mark happily coming out to greet them, "Feng, why are you here?"

"I came to see you specially to see if there is anything I can help with,"

"Feng, we saw the news, you did a great job," Stella took off her mask and gloves and hugged Feng Yiping enthusiastically.

"Haha, that can't be compared with the work you do," Feng Yiping pointed inside, "What stage is it now, what progress have you made?"

"We did a lot of comparative experiments in advance, and the results showed that your battery and Panasonic's battery have better comprehensive performance,"

Feng Yiping had expected this, "If you have any problems, you can directly report to Professor Jiang, and he will organize relevant improvements," It is naturally difficult to say that you don't need to consider Panasonic now, just use your own lithium batteries.

His own company strives to provide supporting services for his own company. For such business, Feng Yiping is also very confident according to procedures.

He specifically reminded Professor Jiang of the importance of this matter.

"You don't know yet? That person is the employee sent by Professor Jiang," Straus pointed to one of them.

Oh, Professor Jiang's arrangement is really good, Feng Yiping praised in his heart, if there are conditions, we should use them. He knew that Panasonic would definitely not be able to enter this laboratory, and Panasonic now probably didn't know how big this order would be in the future.

"Can you tell me what your plan is?" Feng Yiping pointed to the busy crowd inside and asked.

Regarding Tesla, he knows the general technology, but he is not clear about the specific projects below. The only exception is its battery management method.

In this regard, Tesla has promoted it many times, and its competitors have also violently dismantled it many times. It can be said that he can still be an expert in this area.

"This is our plan," Straw brought over a drawing. "Use a very strong glue to stick all the batteries together to make a battery board. For the key cooling, we plan to use air cooling. method, because this method is the lowest cost, but we are still comparing whether it is duct air cooling, fan air cooling, manifold air cooling or other air cooling methods.”

"A whole battery panel?" Feng Yiping entered the performance time, "Straw, Mark, have you ever thought about whether there is a problem with a few batteries in the panel, whether it will affect the entire output, or even bring down A chain reaction?"

"For example, one battery overheated severely, causing a fire, and finally ignited all the batteries?"

"Well," Straw glanced at Mark, "this possibility cannot be ruled out, but we will find ways to avoid it. Feng, do you have any ideas?"

This guy is indeed on his way!

"I think there is a method we can learn from. You also know that for companies like Google, servers are very critical. Not only do we need to reduce the chance of major failures, but our servers are all hosted by professional companies. How can we reduce the risk of major failures? The rent of the venue is also an issue that needs to be considered,”

"In order to reduce the chance of failure and reduce rent, Page and the others have thought of many ways. Our current servers are all customized, reducing unnecessary chassis, and are divided into spaces like bookshelves. One cell, insert a server,"

"We have also designed a program to monitor the operation of the server. If a certain server fails, the control program will respond quickly, shut down the server immediately, and transfer the work it undertakes to other redundant servers. This will have a positive impact on the overall There will be no impact,”

This is indeed a pioneering work of Google, although it was forced out. At this time, Feng Yiping used it as an analogy.

"Then I wonder if our batteries can also be assembled together in this way?"

Feng Yiping casually drew a simple schematic diagram on the paper, "The overall picture is the same as a bookshelf, which is divided into many grids."

"Then, the batteries are divided into units such as boards, cells, and groups based on scale. Each level is uniformly monitored through the chip. At the same time, an independent monitoring and insurance system is set up for the battery units at each level."

"In this way, if a fault occurs on a certain level, the monitoring system will immediately disconnect the insurance of the unit to ensure the stable operation of the remaining levels and other battery units at the same level and prevent the damage from expanding. Is this feasible?"

"Although it sounds like the management and control system will be complicated, this happens to be the advantage of our Silicon Valley. It should be easier to grab an engineer on the road and design such a management system than to ask him to replace the spark plug of the engine. "

"This," Straw and Mark looked at each other, somewhat speechless.

At least the method Feng Yiping mentioned is much more scientific than the method they currently use to glue it into one piece.

Both of them are not ordinary people. If you think about it carefully, it is really feasible. Straw has already added to Feng Yiping's casual sketch, muttering something in his mouth, "A whole, but relatively independent, if there are problems individually, , will not affect the overall situation, and can be monitored in detail,”

He slapped his hands fiercely, "Feng, you are a genius! I think this is a very reliable idea,"

It was necessary to give Straw such an impression from the beginning, "Do you think it's really feasible? What do you think, Mark?"

"It's very feasible, Feng, your idea is indeed genius," Mark said sincerely, "You must come to our laboratory often in the future."

"This is also an idea that came up by chance. Is it really helpful to you? That's great! Haha, it seems that although I am not strong in hands-on skills, I can still provide you with some help."

"Feng, we don't lack people with strong hands-on skills. What we lack are people with genius brains like you. Thank you, you helped us solve a big problem. Now we are confident that the battery section will definitely be the first to produce results." Straw was so happy that he lifted Feng Yiping up.

"Stop, stop," Mark rushed into the laboratory with a smile on his face, "Everyone stop, we have a better idea."
