Chapter 983 Why do they feel like they are not products of the same era?

In the video, Chen Changliu said that the packaging technology and electronic control technology of Zhonghuajia Power's lithium battery are the best in the world. Those who watched the video had different expressions.

Ordinary people had excited expressions on their faces, because Chen Changliu dared to express his position in public, which meant that the flower grower should be the first.

Because in many people's minds, since the establishment of flower growers, they have rarely boasted about how powerful their products are.

It should be said that a flower grower that has been established for 5 years does not promote its own products with as much intensity and intensity as Xikang, which has only been established for more than half a year.

The flower growers said that their technology was the best in the world only three times, and each time they were questioned, but in the end they slapped everyone in the face.

The first time was capacitive screen technology. Now all mobile phone manufacturers around the world are using capacitive screens as the direction of mobile phone development. Maybe some backward areas are still using feature phones, so capacitive screens have not been used yet.

The second time was when Feng Xiao said at the Jade Bird 4 product launch conference that the dual-camera imaging effect of the Jade Bird 4 was the best in the world. At that time, a group of people complained about the low pixels of the dual lenses of the Jade Bird, and the pixels did not reach the top in the industry. Why? There may be such a possibility as 1+1\u003e3.

But after the Jade Bird 4 was finally launched, the functional coordination model of the dual lenses used by flower growers was completely different from others, making the imaging effect really far superior to other brands.

The camera module of the main lens plus the depth of field lens has now become a plan for the entire industry to follow up. It can be said that the technologies claimed by the two cities to be the best in the world have led the trend, allowing not only domestic brands but also foreign brands to keep up.

This time, Chen Changliu said that the lithium battery packaging process and the electronic control system of new energy vehicles of the flower growers are the best in the world. If there is no one, they have to believe it.

After all, to put it bluntly, only flower growers in the world have achieved mass production of pure electric vehicles, so there is really no way to refute his claim that he is the best in the world.

Regardless of whether it is a new thing or not, the technology is not perfect yet, but you can just say that it is the best in the world, right?

The boatman brother who was also watching the video had a dark face and cursed:

"Fart, you weren't even established when we started researching in 2003, why should we say you are number one?"

But he soon became a little tired. The other party had already mass-produced pure electric taxis and had delivered thousands of them. This meant that the flower growers had obtained a large amount of data, which would definitely greatly improve their technology. improve.

As a flower grower, the system is indispensable for mobile phones, so their progress in developing electronic control systems is not comparable to that of ordinary companies.

So after all this calculation, the boatman didn't have that much confidence in his own technology, so he curled his lips and continued watching the video.

"We flower growers have invested a lot of research and development to deal with these causes of spontaneous combustion. We dare not say that we can solve the problem of spontaneous combustion, but we certainly will not spontaneously ignite easily, let alone deflagrate and prevent people from escaping.

First of all, we use a large amount of aerogel in the packaging process.

Aerogel is a solid material with a nanoporous network structure and the pores are filled with a gaseous dispersion medium. It is the lightest solid in the world.

Aerogel is a lightweight nano-porous amorphous solid material with excellent fireproof and thermal insulation properties. After hard work by our team of basic laboratory engineers, we have produced aerogel that meets our needs.

Having said so much, many people must not understand these terms. To put it simply, airgel is a new generation of high-efficiency, energy-saving insulation materials. Compared with traditional insulation materials, the insulation performance of airgel insulation felt is 2-2 times that of traditional materials. 8 times.

Moreover, airgel materials have the characteristics of low density, large specific surface area, and high porosity. These excellent internal structures make it have special properties such as high temperature resistance, low thermal conductivity, low refractive index, and low sound propagation speed. acoustic performance.

As a thermal insulation material, airgel also has good compression properties and can be used as a buffer material between battery cells to adapt to the expansion and contraction of the battery cells during charging and discharging.

And when we package the power lithium battery, we not only place airgel inserts between the cells, but also set mica sheets between the module and the upper cover...

Therefore, these processes can provide continuous cooling technology for the battery, ensuring that the battery always works at a suitable temperature, greatly reducing spontaneous combustion caused by thermal runaway of power lithium batteries.

The cost of the aerogel we use in the encapsulation process reaches thousands of yuan.

It can be said that if you want to reduce the spontaneous combustion of power lithium batteries, the investment cost must not be less..."

In the video, while Chen Changliu was explaining, someone was doing experiments on the insulation effect of aerogels and mica sheets by roasting them with fire. Sure enough, they had the same effect as Chen Changliu said.

At this time, the melon-eaters were confident, but Brother Boatman was different. He stared closely at the piece of aerogel used for experiments in the video. It had higher technological content than their laboratory and was insulated. The effect is better.

“We adopt an isolation design for the battery cells, with a protective plate in the middle, which effectively blocks the spread of thermal runaway battery cells.

When our electronic control system detects abnormalities in battery cell voltage or temperature, it automatically activates the battery rapid cooling system to cool down the battery.

After being punctured by a needle, only the punctured cell module will run out of thermal control without spreading to other cell modules, thereby achieving a high level of safety that prevents the battery system from catching fire.

In summary, our electronic control system can achieve automatic warning, millisecond power off, active cooling, barrier-free exhaust..........

Although our products have not yet been launched, I promise you here that our new energy vehicle three-electric technology has a lifetime warranty..........."

Brother Boatman is a little confused. From the video, Chen Changliu's electronic control system functions and effects, and then think about his own electronic control system, how can this not feel like a product of the same era?

"Finally, the shell of our battery pack is safely protected by the ultra-high-strength steel tic-tac-toe battery shell. The high-strength tic-tac-toe structure, high-strength steel and ultra-high-strength steel account for 98.5%, and the whole pack has super compression resistance. Strong..."

Brother Boatman sat there for a long time without saying anything, because he had no desire to speak, he was a little shocked.

He has always insisted on the strategy of new energy vehicles, and feels that his company's technical reserves in new energy vehicles are definitely the ceiling in China.

But today, from some clues in the video released by Chen Changliu, there is no ceiling. Objectively speaking, he found that his technology in all aspects has lagged behind the flower growers by at least 2 years.

Brother Boatman, who came to this conclusion, took a breath of cold air, and his determination to insist on the new energy strategy almost collapsed.

But he is not an ordinary person, and he finally slowly became firm again.
