After having a simple meal at noon, we continued to sit in the conference room in the afternoon. The director of the power department originally thought that he would have nothing to do in the afternoon, so he was about to leave, but he was stopped by Zhou Wan unexpectedly.

Come down.

Zhou Wan said with a smile: "Since new energy vehicles use electricity, there must be some electricity-related problems. You can also provide some technical support if you stay."

Zhou Wan said this, what else could he say, he could only nod and agree.

From whether a wide range of new energy vehicles can be launched to what energy sources new energy vehicles should use, the scope is shrinking little by little, and the scope is getting smaller and smaller.

In the afternoon, it was about the technical possibilities of new energy vehicles, such as what kind of battery is more suitable for using electricity, how to solve the problem of charging points, the construction of charging piles, and other supporting facilities.

There is also the issue of supporting the Internet and new energy vehicles. The domestic Internet has developed well in the past two years, although the current domestic Internet development is not comparable to that of later generations.

However, the development of the Internet in China is also good. It is not as bad as abroad, but it is not far behind. New energy vehicles that use electricity are inherently connected to the Internet.

The two sides began to have in-depth discussions on this aspect. Throughout the afternoon, Zheng Qingyun began to feel sleepy at the end.

Because he really doesn't understand these things, and he can see it, Jiang Xiaobai doesn't need to escort him, or do anything else.

Judging from how satisfied Zhou Wan is with the new energy vehicles proposed by Jiang Xiaobai, Zhou Wan is probably a staunch supporter of new energy vehicles, needless to say, he is against it.

Zhou Wan is busy with a lot of work. In fact, he is also busy with a lot of things. He is just afraid that Jiang Xiaobai's temper will rise and he will have conflicts with the technology department, which will end badly, so he has turned down a lot of things.

, I have been accompanying you for the past two days.

But now that he is no longer needed, Zheng Qingyun stopped spending time here and took advantage of the break to say goodbye.

"No, I'm leaving now. We just want to have dinner together in the evening." Jiang Xiaobai also persuaded him to stay.

Zhou Wan did the same, and said hurriedly: "Yes, Director Zheng, you must not leave. This trip has caused you so much trouble, and you haven't thanked me properly. How can you leave?"

The two of them strongly tried to persuade him to stay, but Zheng Qingyun stood up, waved his hands and said with a smile: "Okay, we will still have opportunities in the future. We can't see each other until we lower our heads, let alone thank you or anything like that.

It's all for industrial development and domestic enterprise development. Our goals are the same, so I won't be involved in the next thing. You can just talk about it. I'll leave first."

Jiang Xiaobai and Zheng Qingyun were not polite. Since Zheng Qingyun had already said so, he would not stop them.

Zhou Wan also nodded. Of course, he knew that Zheng Qingyun still had some untruths. Not to mention other things, Zheng Qingyun was definitely not just for this. The relationship between him and Jiang Xiaobai was also the reason why Zheng Qingyun appeared here.

reason.

Or it is the main reason. Otherwise, whether it is the industry or the automobile industry, Zheng Qingyun is not in charge of it. What is Zheng Qingyun doing here?

And after arriving, I stayed there for two days, wasn't it because I was afraid that Jiang Xiaobai would suffer a loss?

But seeing through it, Zhou Wan nodded and sent Zheng Qingyun downstairs with Jiang Xiaobai.

Before Zheng Qingyun left, he wanted to have a private chat with Jiang Xiaobai, but the time was not very suitable, so he stopped talking. Anyway, there was still a chance to meet Jiang Xiaobai before Jiang Xiaobai left.

Jiang Xiaobai also saw that Zheng Qingyun had stopped talking, nodded slightly, and just made an appointment later.

Zheng Qingyun got in the car and left. Jiang Xiaobai and Zhou Wan then returned to the office and continued to talk.

In fact, there are still many difficulties and technologies that need to be overcome to replace fuel with electric energy, because many things under the existing fuel vehicle chassis are fixed and cannot be changed casually.

New energy vehicles must be developed based on the technology of original fuel vehicles, rather than comprehensive innovation.

Therefore, the layout of this new energy vehicle still requires some thought and there are some technical issues.

But these things are nothing, just technical issues.

But the only problem is the battery. The fuel tank of the fuel vehicle stores energy. There is nothing to say about this. But the energy source of the electric vehicle is electricity. You can't use the fuel tank to store electricity. Then you must use the battery.

But when using batteries to store electricity, how big and what kind of batteries are needed to store enough electricity to drive a car?

What's more, there is another problem, which is the repeated use of the battery, including the battery life of the tram, etc.

All these problems are concentrated on the battery.

When the electric power director introduced low voltage, medium voltage and high voltage in the morning, he gave an example using an ordinary battery.

The voltage of low-voltage 220v is equivalent to 147 AA batteries connected in series for a total of meters, which is about the height of two floors. This car is so big and needs space and safety. Where should I put so many batteries?

.

Of course, when the director of the power department made the analogy, he was definitely talking about the most common manganese-zinc battery. Other alkaline batteries, lead-acid batteries, lithium batteries, etc. are all stronger than manganese-zinc batteries.

But no matter how powerful the performance is, it is not powerful enough to be placed in a car to provide kinetic energy and endurance to the car.

Zhou Wan knew that one of the difficulties facing new energy vehicles was the battery problem.

When Zhou Wan looked up, it was dark again.

The two of them were in a lively conversation, so of course they had dinner together as a matter of course.

Two people opened a bottle of wine.

Jiang Xiaobai knew that it was time to get down to business. It had been a day and a half. He had already said what he needed to say, and it was also time for Zhou Wan to express his stance.

In the evening, there were only Zhou Wan and Jiang Xiaobai in the private dining room, and not even the secretary came over. Jiang Xiaobai was planning to pour the wine.

But Zhou Wan was asked to hold down the bottle.

Zhou Wan personally took the bottle and poured wine for Jiang Xiaobai. Jiang Xiaobai opened his mouth and wanted to say something, but in the end he held back and poured the wine.
Chapter completed!
