Academic tyrant: I have become a prodigy since I was able to pursue my academic career with peace of

"Anyone else have questions?"Chen Fan asked with a smile.

The audience was silent for a while, and then the senior executive of Xia FAW Company spoke,"I would like to ask Director Chen, you said that the battery , including fast charging?"

As soon as this question came out, everyone looked at Chen Fan with interest and wanted to know his answer.

In fact, it has improved to 350kwh fast charging or not. It is no longer very important.

At least for now, it is not important anymore. After all, driving The mileage is the same as that of ordinary cars.

Even if there is less wear and tear due to fast charging, this is something that car owners can accept.

Of course, as long as the loss is guaranteed to be 70% within three years.

Everyone knows that fast charging technology can shorten the service life of the battery and shorten the charging time, which will cause the heat to cause a decomposition reaction between the battery anode and the cathode.

The faster the charging speed increases, the faster the battery will degrade. Improvement. Naturally, the battery loss will be higher, and this is irreversible, so it is best not to charge quickly.

"President Gao of FAW understands this very well." If you use fast charging all 6,000 times, you can only maintain 83.5% of the power when charging for the first time."

"Can all fast charging still maintain so much power?!"Xia FAW's CEO Gao was stunned.

"Yes. Chen Fan affirmed.

There is no way to ignore the problem of fast charging. When everyone is in a hurry, fast charging for too long will affect the customer experience, so he spent a lot of effort on research.

But even if In this way, he can only increase the loss of fast charging to 83%. If it goes up further, various problems will arise.

"Hua Hua Hua——"

The applause rang out again, and Chen Fan shocked them again and again.

Ma Yun glanced at Mr. Ren Fei, who was sitting next to him, and said with a smile,"Today's world is dominated by young people."

Mr. Ren Fei also sighed with emotion,"The world is changing so fast. How can an old man like me... If you catch up with the current world, your life will not be in vain."

They are looking forward to the next product more and more.

This new product launch will definitely include more than just super storage batteries.

"So will the use of air-cooled equipment damage the battery?"Gerry's boss Dong Xiaozhu asked impatiently without waiting for the applause to stop.

The use of air-cooling equipment will cause the battery degradation rate to accelerate. Now many car companies use passive air-cooling systems to replace liquid cooling systems.

Including her Gerry car, This system is used by Xia FAW's Totem III and others, but the problem is also very prominent. The dynamic air cooling system instead of the liquid cooling system will cause internal heating of the battery, and the degradation rate is twice that of the dynamic liquid cooling battery. The pursuit of ultimate energy density, fast charging technology, and air-cooling equipment are the biggest obstacles to electric vehicles.

This is why owners who buy electric vehicles say that electric vehicles are pitiful. The reason is that they need to replace the battery every three years.

Chen Fan is naturally aware of this problem, so he uses a thermal management solution to alleviate the battery heating problem caused by fast charging technology, but it is different from ordinary thermal management. Same, a special technology is added to it to support fast battery charging

"Won't. Chen Fan said with a smile,"There is a special thermal management material added to the battery, so the problem of battery degradation is almost non-existent.""

These three problems were solved, and there was deafening applause in the venue!

The energy conservation and environmental protection of electric vehicles are originally strongly supported by the state. When buying a car, you can enjoy a certain amount of home subsidies, and for such a model The cost of using a car is low. In addition to these, electric cars can still stand out in the sluggish automobile market! Now the battery range is close to that of ordinary cars. If more efforts are made in charging piles , nothing will be possible in the future.

Stop the rise of electric cars!

The business tycoons sitting in the front row looked at each other, and they could see the excitement and determination in each other's eyes!

This is a big cake!

No one wants to be at a disadvantage!

"Mr. Ma Yun, are you interested?"Bill Gates turned around and said with a smile.

"Hmm, quite interested. Ma Yun said with a smile.

He specializes in the Internet and does not have a car company. But he can invest. There are so many car companies, so he can invest in a few.

It just so happens that Gerry Automobile has his shares. He will discuss it with Dong Xiaozhu. A little more investment would be great

"Is Mr. Bill Gates confident?"Ma Yun said with a smile.

Being able to turn her expensive head and take the initiative to talk to him is obviously telling him something.

He also wants it.

But in this business, whoever pays more money is the winner..

Besides, Chen Fan is from the Xia Kingdom, and with the commotion in the Mei Kingdom some time ago, it is not certain that they, entrepreneurs from the Xia Kingdom, will lose.…..
