Vol 5 Chapter 65: professional advice

The NEXTDOOR park under construction still looks like a large-scale construction project. Most of the buildings have already taken shape, but that's all.

If our domestic construction counterparts and the construction of the park are now not said to be 80% completed, at least half of them should have been completed. But who is the construction workers in the United States, who are all noble workers? Efficiency is never higher.

Feng Yiping is a rare visit. Several bosses of the construction company personally accompanied him. There were also several designers who were also suits and shoes even on the construction site.

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

After taking care of the rapid pace of the domestic construction industry, Feng Yiping was dissatisfied-you know, if the park is completed a day earlier, he can save a lot of rental fees, but he has no alternative.

This is how American workers are doing things without urgency or slowness. This is their fatal flaw.

But at the same time, they all have certain professional skills, and they are very well organized. In addition, professional construction companies have various professional equipment, so everything on the construction site is in order.

Compared with domestic construction sites where there is a lot of enthusiasm, but the on-site management is extremely casual, foreign construction sites have fewer people and are not hurried or slow to do anything. They are very orderly, and on-site management is extremely orderly. It is absolutely two extremes.

A young man who has just entered the workplace is full of energy, hardworking, motivated, and willing to treat his work as a career, but he does not pay much attention to the details and has no experience.

One is an old fried dough stick who has been immersed in the workplace for many years. He is experienced and professional, but it is difficult to mobilize his enthusiasm. It is completely a monk for a day to hit the clock.

But there is a good case here in the United States. There is no need for the owners to worry about safety.

For these construction companies, if there is a safety accident that causes casualties, the consequences, even if they don't go bankrupt, will definitely hurt their lives. Therefore, they are more nervous than Feng Yiping.

With regard to cutting corners and materials, Feng Yiping does not have to worry. If there is a safety accident, the construction company will still have a way to survive, but if it is maliciously cutting corners, once it is verified, there is really no way to survive.

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

"Thank you," in this country where all contracts are talked about, even though Feng Yiping is dissatisfied, he can't say anything. "Please feel free to let me go over there."

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

He said that, as expected, no one followed. The workers on the construction site had consciously regarded the area around the independent small building as a forbidden area.

This was also the first time Feng Yiping came to their laboratory. He clearly saw that there were really traces of smoke on the specially set vent next to it. Is it really such an exaggeration?

It’s really such an exaggeration. After swiping the access card, Feng Yiping discovered after entering the building that the layout of this office is very professional. The outside is a control room with many instruments. Through the glass, you can clearly see the inside. Between laboratories.

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

By the alloy workbench, Stella and Mark, wearing masks and gloves, and their assistants, are "plugging" lithium batteries into a large frame.

Looking at the traces on the wall inside, Feng Yiping didn't want to go in and participate in it. He greeted the loudspeaker in the control room, "Hi,"

When they looked up, Straw and Mark greeted them with joy, "Feng, why are you here?"

"I made a special trip to see you guys and see if there is anything I can help,"

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

"Hehe, it can't be compared with the work you are doing," Feng Yiping pointed inside, "Which step is it now, and what progress is there?"

"We have done a lot of comparative experiments in advance, and the result is that your battery has better overall performance than Panasonic's battery."

Feng Yiping anticipated this, “If you have any problems, you can directly report to Professor Jiang, and he will organize related improvements.” Now it is hard to say that you don’t need to consider Panasonic and use your own lithium battery.

Feng Yiping is also very confident in his own company's efforts to provide matching services to his own company.

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

"Don't you know? That is the employee sent by Professor Jiang," Straw pointed to one of them.

Oh, Professor Jiang’s arrangement is really good. Feng Yiping said in his heart that he should use it if possible. He knew that if Panasonic wanted to enter this laboratory, he would definitely not be able to enter. Besides, the current Panasonic did not know this. How big the list can be in the future.

"Can you tell me what you plan to do?" Feng Yiping asked, pointing to the busy crowd inside.

About Tesla, he knows the general technology, but he really doesn't know the specific projects below. The only exception is its battery management method.

In this regard, Tesla later publicized it many times, and competitors violently dismantled it many times. It can be said that in this area, he can still be an expert in gesticulation.

"We planned this way," Straw brought a drawing. "Using a very strong glue, all the batteries are glued together to make a battery board. The key is to cool. We plan to use air cooling. Because this method has the lowest cost, we are still making comparisons as to whether it is duct air cooling, fan air cooling, manifold air cooling or other air cooling methods."

"A whole battery board?" Feng Yiping entered the performance time, "Straw, Mark, have you ever thought about whether a problem with a few batteries in the battery board will affect the entire output, even with Come chain reaction?"

"For example, a severe overheating caused a fire, and finally ignited all the batteries?"

"This," Straw glanced at Mark. "This possibility cannot be ruled out, but we will try to avoid it, Feng, do you have any idea?"

This guy really hit the road!

"I think there is a way to learn from, and you also know that for companies like Google, servers are very important. Not only do we want to reduce the chance of major failures, but we also choose to entrust our servers to professional companies for hosting. How to reduce The rent of the venue is also an issue that needs to be considered."

"In order to reduce the probability of failure and reduce rent, Page and the others have thought of a lot of ways. Our current servers are all customized, reducing unnecessary chassis, but like a bookshelf, divided into a grid of space. One grid, plug in a server,"

"We have also designed a program to monitor the operation of the server. If a server fails, the control program will respond quickly, shut down that server immediately, and transfer the work it undertakes to other redundant servers. Will not cause any impact,"

This is indeed a pioneering work of Google, although it was forced out, it was compared by Feng Yiping at this time.

"Then I think, can our batteries be assembled in this way?"

Feng Yiping casually drew a simple sketch on the paper, "The whole is like a bookshelf, with many grids inside."

"Then, the battery is divided into units such as board, fast, and group according to the scale. Through the chip, each level is uniformly monitored, and an independent monitoring and insurance system is set up for each level of battery cells."

"In this way, if a certain level fails, the monitoring system will immediately disconnect the insurance of the unit to ensure the stable operation of the remaining levels and other battery units of the same level~www.wuxiaspot.com~ to prevent damage from expanding, is this right? feasible?"

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

"Here," Straw and Mark stared at each other, somewhat speechless.

At least the method Feng Yiping mentioned is far more scientific than the method they are using to glue them together.

Neither of them are ordinary people. If you think about it carefully, it is really feasible. Straw has added Feng Yiping's hand-drawn sketch, saying, "A whole, but relatively independent, individual problems , Will not affect the whole, but can also monitor the details,"

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

Just from the beginning, Straw should have this impression, "Do you think it is really feasible? Mark, what do you think?"

"Very feasible, Feng, this idea of ​​yours is indeed very genius," Mark said sincerely, "You must come to our laboratory often in the future."

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

"Feng, we have no shortage of people with strong hands-on skills. The few are people with talented brains like you. Thank you. You helped us solve the big problems. Now we are confident that the battery section must be the first section to produce results." Straw was so happy to lift Feng Yiping up.

"Stop, stop," Mark rushed into the laboratory with a smile, "Everyone stop, we have a better idea," (to be continued.)
