The NEXTDOOR park under construction is still under construction, and most of the buildings have already taken shape, but that's all.

If we are our domestic construction counterparts, the construction of the park should be completed by 80 percent, not to mention that it is 80 percent complete, but who calls these construction workers in the United States are also aristocratic workers?

Feng Yiping came once, and several bosses of the construction company accompanied him personally, accompanied by several designers who were also suits and leather shoes even on the construction site.

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

After taking care of the speed of the domestic construction industry, Feng Yiping was dissatisfied - you must know that the park was completed one day ahead of schedule, and he could save a lot of rental costs, but he was helpless.

Workers in the United States are like that, they are unhurried, and this is their fatal flaw.

But at the same time, they all have certain professional skills, and they are very disciplined, plus a professional construction company, with all kinds of professional equipment, so everything on the construction site is in order.

Compared with the domestic construction sites that are busy and energetic, but the on-site management is extremely casual, the foreign construction sites have few people, do everything unhurriedly, and the on-site management is extremely orderly, which are definitely two extremes.

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

One is an old fritter who has been immersed in the workplace for many years, experienced and professional, but it is difficult to mobilize his enthusiasm, and he is completely a monk for a day and hits the bell for a day.

But there is a good case in the United States, about safety, the owner does not have to worry about it at all.

For these construction companies, if there is a safety accident that causes casualties, the consequences, even if they do not go bankrupt, will definitely hurt their bones, so they are more nervous than Feng Yiping.

Regarding such things as cutting corners, Feng Yiping doesn't have to worry, if there is a safety accident, then the construction company still has a way to live, but if it is malicious to cut 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 abroad, but because of the high cost of doing so, such things are still rare - at least less than at home.

"Thank you," in this country where everything talks about contracts, although Feng Yiping was dissatisfied, he couldn't say anything, "Everyone, please take care of yourself, I'll go over there and have a look,"

Only one corner of the campus has been completed, and that is the battery lab of Straubel and Marc Tarpenning.

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

This is also the first time Feng Yiping has come to their laboratory, and he can clearly see that there are really traces of smoke on the specially set vents next to him, is it really such an exaggeration?

It's really such an exaggeration, swiped the access control card, and after entering the building, Feng Yiping found that the layout of this office is very professional, the outside is the control room, there are many instruments, through the glass, you can see the laboratory inside very clearly.

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

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

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

They looked up, and Straw and Mark happily greeted them, "Feng, why are you here?"

"I've come to see you guys if there's anything I can do to help,"

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

"Hehe, that can't be compared with the work you do," Feng Yiping pointed inside, "Where are you now, and what progress is there?"

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

Feng Yiping expected this, "If there is any problem, you can directly respond to Professor Jiang, and he will organize relevant improvements," Now it is naturally difficult to say that you don't need to consider Panasonic, just use your own lithium battery."

His own company strives to support his own company, such a business, according to the procedure, Feng Yiping is also very confident.

He specially told Professor Jiang about the importance of this matter.

"You don't know, that's the employee sent by Professor Chiang," Straw pointed to one of them.

Yo, Professor Jiang's arrangement is really good, Feng Yiping praised it in his heart, he should use it if he has the conditions, he knows that Panasonic wants to enter this laboratory, but he will definitely not be able to enter, and the current Panasonic, it is estimated that I really don't know how big this list can be in the future.

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

He knows about Tesla's general technology, but when it comes to the specific projects below, he really doesn't know, the only exception is its battery management method.

In this regard, Tesla has been promoted many times later, and competitors have also violently dismantled many times, so it can be said that in this area, he can still be an expert in pointing fingers.

"That's how we planned," Straw brought a drawing, "with a very strong glue, all the batteries are glued together to make a battery panel, the key cooling, we plan to use air cooling, because this method is the lowest cost, but whether it is pipe air cooling, fan air cooling, manifold air cooling or other air cooling, we are still making comparisons,"

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

"For example, one had a severe overheating, which caused a fire and eventually ignited all the batteries?"

"This," Straw glanced at Mark, "can't rule out the possibility, but we'll find a way to avoid it, von, is there anything you can do?"

This guy is really on the road!

"I think there is a way to learn from, and as you know, for a company like Google, the server is very important, not only to reduce the probability of major failures, but also to choose to hand over our servers to professional companies to host, how to reduce the rent of the site, is also a problem to consider,"

"In order to reduce the probability of failure and reduce the rent, Page and they have thought of a lot of ways, our current servers are all customized, reducing unnecessary chassis, but like bookshelves, divided into a grid of space, each grid, inserted into a server,"

"We also designed a program to monitor the operation of the server, and if one server fails, the control program will respond quickly, immediately shut down that server, and transfer the work it undertakes to other redundant servers, without any impact on the whole."

This is indeed Google's initiative, although it was forced out, and it was compared by Feng Yiping at this time.

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

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

"Then, the battery is divided into plates, fast, groups and other units according to the scale, and each level is monitored in a unified manner through the chip, and an independent monitoring and insurance system is set up for the battery cells at each level."

"In this way, if there is a failure in one level, the monitoring system will immediately disconnect the insurance of that unit to ensure the stable operation of the rest of the level and other battery cells in the same level, and prevent the damage from expanding, is it feasible?"

"Although it sounds like the management and control system will be complicated, this happens to be our advantage in Silicon Valley, and it should be easier to just 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, a little speechless.

At least the way Feng Yiping said is much more scientific than the method they now take to glue it into a whole piece.

Both of them are not ordinary people, think about it, it is really very feasible, Straw has already added it to Feng Yiping's sketch drawn casually, and there are words in his mouth, "A whole, and relatively independent, if there is a problem individually, it will not affect the whole, and it can also be monitored,"

He slapped his face hard, "Feng, you're a genius! I think that's a very solid idea."

It's to get Straw to have the impression from the start, "Do you think it's really possible?" 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 out of nowhere, but it really helps you? That's great! Hehe, it seems that although I am not very hands-on, I can still provide you with some help,"

"Feng, we don't lack people with strong hands-on ability, what is missing is people with genius brains like you, thank you, you helped us solve a big problem, and now we are confident that the battery section must be the first to produce results," Straw was so happy that Feng Yiping was lifted.

"Stop, stop," Mark said with a smile on his face, "everyone stops, we have a better idea," (to be continued.) )
