Seeing Fang Xiaoguang's eager eyes, Zhao Tian didn't hide it, and said directly: "Huawei has officially announced that a new breakthrough has been made in graphene battery technology. ”

After a pause, as if after some consideration, he said cautiously: "I have confirmed this with Mr. Ren..."

Fang Xiaoguang interrupted: "Ren Feifei?"

Zhao Tian glanced at him, Fang Xiaoguang suddenly shrank his head, he just couldn't hold back. After all, a legend like this has heard a lot of people, so I can't help but be a little curious.

Zhao Tian continued: "However, the news given by Mr. Ren is not very good. ”

Lao Chang said with a serious expression: "Could it be that their announcement is just a publicity stunt?"

Then he muttered, "It shouldn't be..."

Zhao Tian waved his hand and denied: "That's not it, what Mr. Ren means is that the graphene battery results researched by Huawei have not fully reached the ideal value set by themselves, and the limitations are relatively large." ”

Fang Xiaoguang's expression was solemn, and he nodded: "These are also one of the dilemmas faced by most graphene research organizations at present. There are too many technical problems in graphene, and the current application scope is also very limited, and it is normal for various technical difficulties to be overcome. ”

"It's just that," Zhao Tian's eyebrows furrowed slightly, and his eyes looked at Fang Xiaoguang, "Although the graphene technology has not yet been perfected, according to Mr. Ren, the current development of small-capacity battery pack test data, the charging speed has reached more than dozens of times that of ordinary batteries, and in addition, the density of batteries of the same quality is also higher than that of ordinary batteries." ”

Fang Xiaoguang's eyes lit up, and he didn't have time to be happy, but he heard Zhao Tian Zhao Tian continue: "But at present, in terms of unit price, it is too expensive. ”

"How much?" Fang Xiaoguanglian asked.

"Under the same capacity, it is more than ten times the cost of ordinary batteries. Zhao Tian grimaced, not knowing what he was thinking.

Fang Xiaoguang's eyes darkened.

Such a price may be possible for scientific research purposes, but it is almost unrealistic if it is used for mass production and sales.

But soon Fang Xiaoguang's mind turned back, since Zhao Tian called the two of them over, and mentioned the matter of graphene, he would definitely not just tell him how expensive that thing was, there must be a following.

Sure enough, after saying this, Zhao Tiancai entered the topic: "I have already agreed with Mr. Ren that I will first ask them to provide two sets of batteries with a capacity of 20Ah for the research and development of our new energy vehicles." ”

Fang Xiaoguang's eyes suddenly lit up again.

He knew that his chairman would not be idle and bored to popularize these things for him.

But immediately, Fang Xiaoguang recovered from the surprise and was a little dissatisfied with the battery capacity that Zhao Tian said.

At present, the battery pack capacity of mainstream electric vehicles on the market is between 50Ah and 60Ah, and 20Ah is inevitably too small.

Even if the graphene battery theoretically stores three to five times the power of ordinary batteries, from Zhao Tian's introduction just now, Huawei's research and development results this time are obviously still far from this result.

This almost means that 20Ah is 20Ah, without any expansion.

According to the highest voltage conversion, the two sets of batteries can reach 8Kh, which is only half of the power of mainstream cars on the market.

If it is converted into mileage, based on the consumption of 10 to 15 kilowatt-hours of electricity per 100 kilometers, such a battery capacity cannot even reach 100 kilometers.

What is the use of it.

Before Fang Xiaoguang could complain, Zhao Tian gave the answer: for research.

Hearing Zhao Tian say this, Fang Xiaoguang had no choice but to ask sullenly: "Then this battery will be used in the design of the finished model this quarter?"

"Finished model?" Zhao Tian looked puzzled.

Lao Chang hurriedly interjected: "Yes, Mr. Fang has planned to design a finished model this quarter, so as to make progress in the new energy vehicle business." ”

Fang Xiaoguang glanced at Lao Chang with slanted eyes, he had already tasted the meaning of this.

Seeing that Lao Chang said this, Zhao Tian nodded in agreement, "Well, the new energy vehicle should also come up with something." ”

With a subtle smile, Lao Chang glanced at Fang Xiaoguang lightly.

After a few more words, the two of them left Zhao Tian's office.

After the two left, Zhao Tianfang felt a little painful.

These two humble sets of batteries alone cost him nearly seven figures.

You know, it's just two sets of batteries.

In addition, this kind of large-capacity graphene battery was only obtained by Zhao Tian after using his previous favors.

Otherwise, no matter how high the price is, Huawei may not be able to give it.

For the time being, the matter on Lao Chang's side was over, and Zhao Tian began to set his eyes on Huang Houcai again.

As mentioned at the board meeting, the electrical business has begun to stagnate, and intends to solve it by opening up new markets, Zhao Tian is ready to inquire about the preparation and progress of Huang Houcai's related matters.

"Zhao Dong. As soon as Zhao Tian's phone rang twice, Huang Houcai's voice came.

Zhao Tian didn't ink, and went straight to the point and asked, "How is the research and development of the new security system?"

Naturally, he asked about Wu Yan's mention, expanding the electrical business from the original only for sedan models to all other models, the most important of which is naturally truck models.

Huang Houcai's bitter voice came from the phone: "Zhao Dong, this is really hard to say!"

Zhao Tianxia subconsciously frowned, "Let's talk about the situation!"

Huang Houcai said: "Regarding the safety system of the truck model, our technical team has also had relevant research topics before, but we have not paid too much attention to it. But now that I have gone deeper, I find that there are many difficulties. ”

He then explained: "Unlike the built-in systems of sedan models, the new safety systems of truck models must be designed in the form of a combination of interior and exterior due to the large size and the exposure of related components. ”

"In addition, one of the ICCs we originally applied in the sedan model is completely unsuitable for the truck model, and in the latest research results, at least three branch ICCs must be used, and finally merged into a general ICC system to meet the use of various functions. ”

Listening to Huang Houcai's complaints on the phone, Zhao Tian touched his chin and fell into thought.

According to what Huang Houcai said, not to mention the rest, the cost of the safety system for truck models alone has increased several times.

In addition, the driving safety system is used as an auxiliary function on the use of car functions, if the cost is too high, many car companies in production, considering the market sales situation, will inevitably consider the cost, the safety system PASS directly.

In this way, even if it is developed, it is useless and purely superfluous. ()
