Chapter 243 Play with an individual exoskeleton?
deep city.

Not long after the meeting over the sea ended, Ye Zhou received a special invitation letter from MWC, inviting him to participate in that year's MWC as a special contributor.

The meeting organizer's words were extremely sincere, but Ye Zhou wanted to laugh.

What promoted the development of world communication technology, what benefited underdeveloped countries with cheap technology, and what broke the monopoly pattern
I bother!

Although the countries hosting MWC do not belong to the ranks of hard-core dog-licking ugly countries, they still belong to the same camp.

Since he belongs to the same camp, he has no reason to brag about himself like this.

Ye Zhou didn't know what they were planning, but it was impossible for him to participate in such an exhibition that required going abroad.

What are you going to do?Exchange technical experience?
But the problem is, I am a wall hanger!

What can we communicate?Hacking experience?
Stop bullshitting.

Not to mention the huge security pressure he would face if he left the country once with his current status, maybe the money for a trip abroad would be enough to build a simple road for some underdeveloped areas.

He himself is a person who is extremely cost-effective, and he doesn't even intend to consider such an obviously low-yield matter.

Watching him throw the invitation letter into the wastebasket, Chen Hao asked curiously:

"Don't want to go abroad to see it? Barcelona, ​​whether it's natural scenery or urban scenery, it's very charming."

"Now is not the time. When will the Golden Crow start cruising around the world, and I can't go where I want to go? Why are you in such a hurry, the great rivers and mountains in China are not enough for me to see? I haven't even finished visiting the scenic spots in China."

"That's right. Shall I arrange for you to go shopping in the country during this time?"

Ye Zhou looked at Chen Hao helplessly, and said:
"Don't think that I don't know what you mean, isn't it just a vacation in disguise? I really have enough rest, so don't bring up this topic again. Well, if I really feel tired, I won't procrastinate. Let's go and see the battery test, the first batch should have rolled off the production line today, right?"

Chen Hao nodded and replied:

"I just downloaded it two hours ago, and now I'm doing a cycle charge and discharge test. In fact, there is no need to look at it, just wait for the result."

"Then I have to find something to do! I've been here for two days and I haven't done anything."

"This is the meaning of the establishment of the General Technical Office! If you need to do all the trivial things, then what's the point of the General Technical Office?"

Ye Zhou was taken aback for a moment, then sat down again.

Yes, there are still a lot of technologies that need to be brought out in the future, and it is impossible to do everything by myself, otherwise I will not be able to keep up in terms of time and energy.

The reason why I still have such thoughts subconsciously is purely because the previous habits have not been changed.

"Okay, you're right, let's talk about the follow-up plan first."

Chen Hao nodded and sat down, turned on the PAD in his hand to cast the screen, and began to introduce the battery test and release plan to Ye Zhou.

The General Technical Office with him as the core has already made all the preparations. Once the battery experiment is successful, it will release this battery in an absolutely shocking way and from an official standpoint.

What they have to do is not only to release batteries, but more importantly, to use this opportunity to completely break the domestic concerns about new energy sources.

While the two were chatting about the next step, in the laboratory, the engineers had also completed the last test of the sulfur-silicon battery.

The test results were made into reports and projected on the big screen.

"The energy density is between 980 and 1100, and there are certain fluctuations, but the difference is most likely due to the immature manufacturing process. Judging from the average fluctuation, it should be considered a success, right?"

"Well, I think it's a success. You see, although the performance of this batch of batteries has fluctuated, the fluctuation range is very narrow and not continuous. The high probability is that some independent operating errors caused the performance to decline. , which can be said to be unavoidable during the first trial production process."

"Xiao Liu, go and compare the results of the first trial production of the 4680 battery to see if the data fluctuations are normal."

"Leader, let me cast it on the screen next to me."

While talking, the researcher named Xiao Liu was operating on his computer, and within a few seconds, another report was projected onto the screen in a synchronous display.

"Hey, the group energy density of 4680 is only 240WH/KG? What's wrong, I thought 4680 was already very advanced."

"This is probably the difficulty of going from extravagance to frugality. What did we do with batteries before? Optimizing CTP, optimizing the stacking scheme of cells, optimizing the stacking process, and even optimizing the material of PACk, can have a 20% improvement. Enough to issue project bonuses.”

"What about now? It suddenly went from a small three-digit number to a four-digit number, and looking back, I really don't like it."

"That's right...the distribution of data errors is similar, so there shouldn't be any major problems."

After reading the comparison of the analysis reports, the researchers finally settled down.

After nearly three weeks of hard work, their work is finally complete.

Now, we only need to wait for the combination of the battery cell and the magazine battery pack system, and after it is moved to the new energy vehicle, it can be handed over to the General Technical Office for release.

They still don't know how the other party will release the new battery for the time being, but everyone has actually received some wind --- or guessed some clues from what they were asked to do.

"So, this time the battery is directly put into the car, and the above is planning to directly test how far a new battery can run?"

"No news, but I think it should be. After all, the intention of the government to develop batteries this time is obvious, which is to impact gasoline vehicles—or impact the energy market."

"It's useless for you to tell consumers about those technical indicators, and they don't understand. The best way is to build the car and throw it in front of them for them to see."

"I don't understand what density and capacity are, but you can always understand the mileage, right? How far a car can run, how many times it needs to be charged, and how long each charge takes, is this intuitive enough?"

"So, when we first started the project, the goal set by the General Technical Office was to put the battery on the car, and that's probably the purpose."

After listening to his analysis, the other researchers nodded one after another. After a short pause, someone asked again:

"This time the energy density of the battery cell has soared, how much can it be converted into mileage?"

"Hard to say."

The team leader shook his head, then continued:
"The specific mileage also needs to consider the weight of the vehicle, the layout of the battery pack, the power management scheme, the driving status and even the road conditions, etc. In the end, it depends on what kind of method the official will use to test."

"They definitely won't choose fixed closed road sections, otherwise there is no need to go through such a lot of trouble... But, no matter what, if this battery is put in the car, it should be easy to run [-] kilometers. "

"Even the charging speed is also extended. Originally, the charging of sulfur-silicon batteries is considered very fast, but with a large capacity, the time will also be prolonged."

"It's not too long, is it, Team Leader? According to our estimation, it only takes half an hour to fully fill the magazine group. Compared with the effective driving time, the ratio is not much different from that of a gasoline truck."

"Forget it, don't worry about it, has the report been sorted out? Send it to the leader!"

.........

A few minutes later, Ye Zhou received the latest performance test report of the sulfur-silicon battery from the laboratory.

The volume energy density is 1900WH/L, the group energy density is expected to be 1000WH/KG, the discharge high-efficiency area is 30%~80%SOC, and the overall parameters fully meet the expected standards.

According to this data estimate, the energy storage performance of silicon-sulfur batteries has been improved by more than 4 times compared with existing products in the market.

"Does this look like the internal combustion engine replaced the horse-drawn carriage? Karl Benz's two-stroke single-cylinder gasoline engine ended the era of the horse-drawn carriage. Will our battery also end the era of oil vehicles? Its performance advantage is too obvious, whether it is mileage or usage. The cost is much lower than that of traditional oil trucks."

Chen Hao asked with some expectation.

Ye Zhou shook his head and replied:

"Oil trucks are not that easy to replace, it's a slow process."

"What we have to do is not to overthrow all oil trucks at once, but to open up a wider road through it."

"Moreover, this battery is not only designed for new energy vehicles, it can be used in many fields, such as aircraft, submarines, wind power, ship all-electric systems, mining equipment... In short, new energy vehicles are just the beginning, the next step There are many more applications to be done."

"For example, with such a large energy density, why don't we try to make an individual exoskeleton armor for fun?"
