Shenzhen City.

Shortly after the meeting on the other side of the sea, Ye Zhou received a special invitation from MWC to invite him as a special contributor to attend MWC of that year.

The organizer of the conference was extremely sincere, but Ye Zhou wanted to laugh.

What has promoted the development of world communication technology, what has used cheap technology to benefit underdeveloped countries, and what has broken the monopoly pattern...

I'm gonna be!

Although the country hosting MWC is not a member of the ranks of the ugly country's hardcore dog licking dogs, 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 the abacus they were about, but he would not be able to attend such exhibitions that needed to go abroad.

What to do? Exchange technical experience?

But the problem is, I am a wall hanging!

What can I communicate? Experience in cheating?

Stop talking nonsense.

Not to mention the huge security pressure that you have to face when you go abroad once as your current identity. Perhaps the money you go abroad once will be enough to build a simple road for some underdeveloped areas.

He himself is a person who is extremely pursuing cost-effectiveness ratio. He doesn't even intend to consider such a significantly low-yield thing.

Seeing him throwing the invitation letter into the wastebasket, Chen Hao asked curiously:

"Don't want to go abroad to see it? Basel, both natural scenery and urban scenery are very charming."

"Now is not the time. When will the Golden Crow start the global cruise? Where can I go? Why are you in a hurry? The country is not enough for me to see? I haven't even finished visiting domestic attractions."

".........I'm right. Do you want to arrange for you to visit the country during this period?"

Ye Zhou glanced at Chen Hao helplessly and said:

"Don't think I don't know what you mean. Isn't it just a disguised vacation? I've really had enough rest. Don't mention this topic in the future. OK, if I really feel tired, I won't drag it. Let's go and check the battery test. The first batch of people should have been off the production line today, right?"

Chen Hao nodded and replied:

"I just got off two hours ago and am now doing a cyclic charging and discharging test. There is actually no need to check it out, just wait for the results."

"Then I always have to find something to do! I have been here for the past two days and have done nothing."

"This is the significance of the establishment of the General Technical Office! If you need to do any trivial matters, what is the significance of the General Technical Office?"

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

Yes, there are still a lot of technology that needs to be produced later. It is impossible to do everything yourself, otherwise you will not be able to keep up with it in terms of time and energy.

The reason why I subconsciously thought this is purely because my previous habits have not been changed.

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

Chen Hao nodded and sat down, opened the pad projection screen in his hand, and began to introduce Ye Zhou to the battery test and release plan.

The General Technical Office with him as the core has made all preparations. Just wait for the battery experiment to be successful, it will be necessary to release the battery from an absolutely shocking way and from an official standpoint.

They want to do not just release batteries, but more importantly, take advantage of this opportunity to completely break domestic concerns about new energy.

......

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

The test results are made into reports and are projected onto the large screen.

"The energy density is between 980 and 1100, and there is a certain fluctuation, but it is likely that the difference caused by immature production process. Judging from the average fluctuation, it should be considered successful, right?"

"Well, I think it's a success. You see, although the performance of this batch of batteries fluctuates, the fluctuation distribution range is very narrow and it is not continuous. It is likely that performance degradation caused by some independent operational error events, which can be said to be inevitable during the first trial production."

"Xiao Liu, go and compare the first trial production results report of 4680 battery to see if the data fluctuates normally."

"Team leader, I'll cast it on the screen next to me."

While speaking, the researcher named Xiao Liu operated on his computer. In a few seconds, another report was cast on the screen in a synchronous display.

"Wow, the energy density of 4680 is only 240wh/kg? What's wrong? I thought 4680 was already very advanced."

"This is probably because it's difficult to go from luxury to frugality. What did we do in the past when we used batteries? Optimizing ctp, optimizing battery cell stacking scheme, optimizing the stacking process, and even optimizing the material of the pack. If you can get a 20-plus, you will be able to get a project bonus."

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

"No... the data error distribution is almost the same, so there should be no major problems."

After reading the analysis report, the researchers finally settled down.

After nearly three weeks of hard work, their work is finally about to be completed.

Now, you only need to wait for the battery cell and magazine battery pack system to be combined and moved to the new energy vehicle, and then you can hand it over to the General Technical Office for release.

They don't know how the other party will release this new battery at the moment, but everyone has actually received some news - or in other words, they have guessed some clues from what they are asking them to do.

"So, this time the battery is directly on the car. The above plan to directly test how far a new battery can go?"

"There is no news, but I think it should be, after all, the official intention of getting a battery this time is very obvious, it is to impact the oil trucks--or the energy market."

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

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

"So, when we started the project, the goal set by the General Technical Office for us was to get the battery on board, and this is probably the purpose."

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

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

"It's hard to say."

The team leader shook his head and continued:

"The specific mileage also requires consideration of the vehicle weight, battery pack layout, power management plan, driving status and even road conditions, etc. How much in the end depends on what method the official needs to use to test it."

"They definitely won't choose a fixed closed section, otherwise there would be no need to go through such a lot of trouble... But no matter what, if this battery cell is placed on the car, it should be easy to run for 2,000 kilometers."

"Even if the charging speed is also extended, the charging calculation of sulfur silicon batteries is very fast, but if the capacity is large, the time will be longer."

"It's not that long, the team leader? According to our estimate, the magazine group is only half an hour long. Compared with the effective driving time, the proportion is not much different from that of the fuel truck."

"This is... forget it, don't worry about this, have the report sorted out? Send it to the leader!"

………

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

The volume energy density is 1900wh/l, the group energy density is expected to be 1000wh/kg, the discharge efficient zone is 30%~80%soc, and the overall parameters fully meet the expected standards.

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

"Is this like the past internal combustion engines replace carriages? Calbenz's two-stroke single-cylinder gasoline engine ended the carriage era. Will our battery also end the era of oil vehicles? Its performance advantages are too obvious. Whether it is mileage or usage cost, it is much lower than that of traditional oil vehicles."

Chen Hao asked with some anticipation.

Ye Zhou shook his head and replied:

"The oil truck is not so easy to replace, it's a slow process."

"What we are going to do is not to overturn all the fuel trucks at once, but to open up a wider road through it."

"And, 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 full-electric systems, mining equipment... In short, new energy vehicles are just the beginning, and there are more applications to be done in the next step."
