Vol 2 Chapter 532: Power wireless remote directional transmission technology

Latest URL: New Technology? The crowd under the stage couldn't help wondering.

Wu Hao's technological breakthroughs in battery energy have been very bright, and several major technology launches have shocked the world.

So what is the new technology in Wu Hao's mouth this time, everyone looks forward to it.

Wu Hao, meanwhile, looked at the crowd and continued, "Because the space available for the whole pair of glasses is very limited, we can only make an article in the hollow position of the limited frames and legs .

Except for installing a large number of electronic components, the space reserved for the battery is very small. Although the latest super solid state battery is not available, we have developed a new generation of commercial batteries based on the original new lithium battery. The performance of this battery is 30% higher than the original new lithium battery.

And this time, we are also the first to apply this latest lithium battery to this smart AR glasses. Although the battery placed in it is small, it has reached an amazing 800 milliamps. "

Oh, slap slap slap ... When everyone on the stage saw the data on the big screen, they couldn't help cheering and applauding.

In addition to some of the specially invited fans, the professional media and guests of the audience also nodded and praised. It's really amazing to be able to fit a 800 mAh battery in such a small space.

"It can't be more, it won't fit any more, and the weight will increase, which will affect our wearing experience. Time will make everyone feel tired.

Therefore, after repeated experiments, we set it at the balance of 800 mA.

There is no room to upgrade, but there is actually. It's just that we use it to place other parts, and it also has a crucial impact on the life of this smart AR glasses.

Why do you do that? "

Wu Hao raised a question, then paused to give everyone some time to think, and then continued: "Because the power of this smart AR glasses is relatively large, it is simply too expensive. Even if equipped with these 800 millimeters An battery can only support it for six and a half hours.

The reason why it costs so much electricity is mainly because of its transparent display screen, and the power consumption of various lens sensors and other parts all over it.

The first is a transparent display screen. In order to have sufficient display brightness and color saturation, as well as high-definition image quality and ultra-high refresh rates, it is relatively power-hungry, and it can be said that it is the number one power consumer in the entire device.

Then there are these lenses. Unlike the mobile phones we use, these lenses must work all the time, so they consume more power.

A little understanding knows that whether you use a mobile phone or a camera to take pictures, it is the most power-consuming.

So even if we equip this smart AR glasses with a 800 mAh battery, it still cannot meet its long-term use.

Of course, under normal circumstances, the battery life of six and a half hours is already very good, which can meet our most basic use requirements.

but……"

Wu Hao replied heavily, then shook his head and said, "I'm not satisfied because it's not perfect. For many moderate and heavy users, this time is far from enough, so we must solve this problem."

"How to deal with it?"

"Our R & D team and designers have thought of many ways, such as sacrificing aesthetic appearance and wearing experience, and adding larger and heavier batteries with longer battery life.

Alternatively, an interface is provided on the temple part of the smart AR glasses, and then a part similar to a headphone cable is connected to another power supply device for continuous power supply.

This solution is good or good, and there is no need to change the appearance and weight of the smart AR glasses, but it has an extra line, which is troublesome and annoying. I don't like it, so can I remove this line? "

how can that be? This is the first answer in the minds of the vast majority of the audience who heard Wu Hao's question. And a small number of people are in front of them, staring at Wu Hao in anticipation of his next answer.

Wu Hao did not let everyone wait for a long time, but nodded with a smile: "In fact, it is possible. We have already used a lot of daily wireless charging technology to meet this requirement.

Some people have asked, the current wireless charging technology is charging close to the object. What is the difference between this and plugging in? It still hasn't solved the problem. "

In a different tone, he continued: "It did not solve the fundamental problem, but provided our engineers with a solution. Is it possible for us to come up with wireless charging technology that can perform remote charging?"

"Remote charging?"

"Wireless charging technology?"

"crazy?"

"how can that be……"

The audience immediately became very noisy, and everyone was talking head-to-head. It was obviously startled by Wu Hao's statement.

Not only the live audience, but also domestic and foreign audiences who are watching the live broadcast also quarreled. At one time, this issue was discussed in various live broadcast rooms, forums, communities, and even social software.

But Wu Hao did n’t give everyone much time for discussion, but pressed his hands to calm everyone down and said with a smile: "Yes, many people were shocked when they first proposed this plan. One after another felt that this was simply impossible.

But I like this solution very much, because it is creative enough, and I don't like to challenge these impossible things that everyone says. "

"In fact, the principle of wireless charging technology is very simple. At present, there are several relatively mature technical solutions, such as electromagnetic induction type, electromagnetic resonance type, radio wave type ~ www.readwn.com ~ electric field coupling type and so on.

However, all of these wireless charging technologies have a common problem, that is, long-distance power transmission cannot be achieved, or the loss during the long-distance transmission is too large to meet the practical requirements.

There are many reasons why this is the case. The most important ones are that the power of the transmitter and receiver is too low, and the electromagnetic wave is not concentrated enough.

And our R & D team worked together with our battery and energy power research laboratory. After experiencing difficulties, we finally overcome this technical problem and developed the wireless wireless remote directional transmission technology. "

coax! The noise is much louder this time than just now, and the same is true on the Internet.

The live media is the first time to report on the front page of the website in black font, the title is "Haoyu Technology released major scientific and technological achievements, wireless remote charging technology was born, or it will change the entire world."

Wu Hao, who was standing on the stage, watched the sensational crowd show his white teeth, then nodded solemnly, and announced loudly: "Yes, we have come up with wireless remote charging technology."
