Great Power Technology

Chapter 243: Make a personal exoskeleton for fun?

Deep city.

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

The organizer of the conference spoke very sincerely, but Ye Zhou wanted to laugh.

What has promoted the development of world communications technology, what has benefited underdeveloped countries with cheap technology, and what has broken the monopoly pattern

I bother!

Although the countries hosting MWC do not belong to the ranks of hard-core 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 their plan was, but it was impossible for him to attend such an exhibition that required traveling abroad.

Go for what? Exchange technical experience?

But the problem is, I am a wall hanging!

What can we communicate? Cheating experience?

Stop talking nonsense.

Not to mention the huge security pressure he would face if he went abroad in his current capacity. Maybe the money spent on one trip abroad would be enough to build a simple road in some underdeveloped areas.

He himself is a person who extremely pursues cost-effectiveness. He has no intention of even considering such a significantly low-yield thing.

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

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

"Now is not the time. When will the Golden Crow start a global cruise? Where can't I go where I want to go? Why are I in such a hurry? There are not enough beautiful places in the country for me to see? I haven't even visited the domestic attractions yet."

"That's right. Do you want to make some arrangements for you to go shopping in the country during this time?"

Ye Zhou glanced at Chen Hao helplessly and said:

"Don't think that I don't know what you mean. Isn't it just a disguised vacation? I've really rested enough. Don't bring up this topic again in the future. Okay, if I really feel tired, I won't procrastinate. Let’s go and check out the battery test, the first batch should have rolled off the production line today, right?”

Chen Hao nodded and replied:

"I just took it off two hours ago, and I'm doing a cycle charge and discharge test now. There's actually no need to see it, just wait for the results."

"Then I have to find something to do! I've been here for two days and 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 stunned for a moment, then sat down again.

Yes, there are still a lot of technologies that need to be used in the future. It is impossible to do everything by yourself, otherwise you will not be able to keep up in terms of time and energy.

The reason why I still have such thoughts subconsciously is simply because I haven't changed my previous habits.

"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 project the screen, and began to introduce the battery testing and release plan to Ye Zhou.

The General Technical Office with him as the core has made all preparations. As soon as the battery experiment is successful, the battery will be released in an absolutely shocking way and from an official position.

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

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

The test results are made into a report and projected on the big screen.

"The energy density is between 980 and 1100. There is a certain fluctuation, but the difference is most likely caused by the immature production 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 fluctuates, the fluctuation range is very narrow and there is no continuity. There is a high probability that the performance is degraded due to some independent operating errors. , which can be said to be inevitable during the first trial production process.”

"Xiao Liu, go get the first trial production report of the 4680 battery and compare it to see if the data fluctuation is normal."

"Team leader, let me cast it on the screen next to you."

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

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

"This is probably because it is difficult to go from luxury to frugality. What did we do in the past when making batteries? Optimizing CTP, optimizing cell stacking scheme, optimizing lamination process, and even optimizing the material of PACk. If we can achieve a 20% improvement It’s enough to issue project bonuses.”

"What now? It suddenly jumped from a small three-digit number to a four-digit number. Looking back, it's really a bit disdainful."

"No...the data error distribution is similar, so there shouldn't be any big problem."

After reading and comparing the analysis reports, the researchers finally calmed down.

After nearly three weeks of hard work, their work was finally completed.

Now, we only need to wait for the battery cells and magazine battery pack system to be combined and moved to the new energy vehicle before they can be handed over to the General Technical Office for release.

They don't yet know how the other party will release this new battery, but everyone has actually received some rumors - or, in other words, guessed some clues from what they were asked to do.

"So, this time the battery is put directly into the car. The plan is to directly test how far a new battery can run?"

"There is no news, but I feel it should be. After all, the official intention of developing batteries this time is very obvious, which is to impact oil trucks - or to impact the energy market."

"It's useless for you to tell consumers about the technical indicators. 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 understand the mileage, right? How far can a car run, how many times does it need to be charged, and how long does it take to charge each time? This is intuitive enough, right?"

"So, when we first started the project, the goal set for us by the General Technical Office was to put the battery on the car. This is probably the purpose."

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

"This time the battery cell energy density has soared. How much can it be converted into mileage?"

"Hard to say."

The team leader shook his head and continued:

"The specific mileage also needs to consider the vehicle weight, battery pack layout, power management scheme, driving status and even road conditions, etc. The final mileage depends on what method the official uses to test."

"They will definitely not choose to fix the closed road section, otherwise there is no need to go to such trouble... However, no matter what, if this battery is placed in the car, it should be easy to run 2,000 kilometers. "

"Even the charging speed is also being extended. Originally, sulfur-silicon batteries can be charged very quickly, but with a large capacity, the time will also be lengthened."

"That's not too long, right, team leader? According to our estimates, it actually only takes half an hour to fill the magazine group. Compared with the effective driving time, the ratio is actually not much different from that of a gasoline truck."

"Forget it, don't worry about it. Have you compiled the report? 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 volumetric energy density is 1900WH/L, the group energy density is expected to be 1000WH/KG, and the discharge efficiency area is 30%~80%SOC. The overall parameters fully meet the expected standards.

Based on this data, it is estimated that the energy storage performance of silicon-sulfur batteries has been improved by more than four times compared to existing products on the market.

"Is this like the internal combustion engine replacing horse-drawn carriages in the past? Karl Benz's two-stroke single-cylinder gasoline engine ended the era of horse-drawn carriages. Will our battery also end the era of oil cars? Its performance advantages are too obvious, both in terms of mileage and use. The cost is much lower than that of traditional oil trucks.”

Chen Hao asked with some anticipation.

Ye Zhou shook his head and replied:

"Oil trucks are not easily replaced. This is a slow process."

"What we want to do is not to overturn all the oil trucks at once, but to open up a wider road through them."

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

"For example, with such a high energy density, why don't we try to build a single-soldier exoskeleton armor for fun?"
