Technology? Everyone in the audience couldn't help but be curious.

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

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

As for Wu Hao, he looked at the audience and continued unhurriedly: "Because the space that can be used on the whole pair of glasses is very limited, we can only make a fuss in the limited frame and the hollow position in the temple.

In addition to the installation of a large number of electronic components, there is very little space reserved for the battery. Although the latest super solid-state batteries are not usable, we have developed a new generation of commercial batteries based on the original new lithium batteries, which are 30% better than the original new lithium batteries.

And this time, we are also the first to apply this latest lithium battery to this smart AR glasses. Despite the small size of the battery that was placed inside, it reached a staggering 800 mAh. ”

Oh, pop, bang...... After everyone in the audience saw the data on the big screen, they couldn't help cheering and applauding.

In addition to some coaxing special fans, the professional media and guests in the audience also nodded in admiration. To be able to fit an 800 mAh battery in such a small space is truly remarkable.

"We can't put any more, we can't put it down, and the weight increases, which affects our wearing experience. Time is a game, and everyone will feel very tired.

So, after repeated experiments, we settled on the balance compromise point of 800 mAh.

There is still room for upgrades, in fact, there is. It's just that we use it to place other parts, and it also has a crucial impact on the battery life of this smart AR glasses.

Why? ”

Wu Hao threw out a question, then paused, giving everyone some time to think, and then continued: "Because the power of this smart AR glasses is relatively large, simply put, it is too much electricity." Even with this 800 mAh battery, it can only support it for six and a half hours.

The reason why it consumes so much electricity is mainly because of its transparent display screen, as well as the power consumption of various lens sensors and other components all over its body.

The first is the transparent display screen, which consumes more electricity in order to have sufficient display brightness and color saturation, high-definition image quality and ultra-high refresh rate, and can be said to be the largest power consumer in the entire device.

Then there's the lenses, which, unlike the phones we use, have to work all the time, so they're more power-hungry.

Those who know a little bit know that whether you use a mobile phone or a camera to take pictures, it is the most power-hungry.

So even if we equip this smart AR glasses with an 800 mAh battery, it still can't meet its long-term use.

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

But ......"

Wu Hao said in a heavy tone, then shook his head and said, "I'm not satisfied because it's not perfect." For many moderate and heavy users, this is not enough, so we have to solve this problem. ”

"How to fix it?"

"Our R&D team and designers have come up with a lot of ideas, such as sacrificing aesthetics and wearing experience to add larger, heavier batteries with longer battery life.

Alternatively, set up an interface on the temples of the smart AR glasses, and then connect it to another power supply device with a part similar to a headphone cable for continuous power supply.

This solution is good, and it doesn't need to change the appearance and weight of smart AR glasses, but there is an extra line, which is very troublesome and annoying, I don't like it, so can you remove this line? ”

How is this possible? This is the first answer that comes to mind in the minds of the vast majority of viewers who hear Wu Hao's question. As for the other small number of people, their eyes lit up, staring at Wu Hao, looking forward to his next answer.

Wu Hao didn't let everyone wait for a long time, but nodded with a smile: "Actually, it's possible, we have used a lot of wireless charging technology in daily life to meet this requirement."

But someone asked, the current wireless charging technology is close to the object for charging, what is the difference between this and plugging in the cable, or it has not solved the problem. ”

In a different tone, he continued: "It doesn't solve the fundamental problem, but it provides our engineers with a solution, that is, can we come up with wireless charging technology that can be charged remotely." ”

"Remote charging?"

"Wireless charging technology?"

"Crazy?"

"How is this possible......"

The audience instantly became noisy, and everyone was talking about it one after another, obviously startled by Wu Hao's statement.

Not only the live audience, but also the domestic and foreign viewers who were watching the live broadcast also quarreled. For a while, this issue was discussed in various live broadcast rooms, forums, communities, and even social software.

But Wu Hao didn't give everyone too much time to discuss, but pressed his hand to calm everyone down, and said with a smile: "Yes, after this plan was first proposed, many people were startled, and they all felt that this was impossible, it can be said to be a fantasy.

I, on the other hand, love the idea because it's creative enough, and I don't really like to challenge the impossible. ”

"In fact, the principle of wireless charging technology is very simple, and there are several relatively mature technical solutions, such as electromagnetic induction, electromagnetic resonance, radio wave, electric field coupling, etc.

However, these wireless charging technologies have a common problem, that is, they cannot realize long-distance power transmission, or the loss is too large in the process of remote transmission, which cannot meet the practical requirements.

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

Our R&D team, together with our battery and energy power research laboratory, finally overcame this technical problem and developed the wireless remote directional transmission technology of power. ”

Coax! This time the noise in the audience was louder than it had just been, and it was the same on the Internet.

The live media reported in black font on the front page of the website for the first time, with the title of "Haoyu Technology released major scientific and technological achievements, wireless remote charging technology was born, or will change the whole world." ”

Wu Hao, who was standing on the stage, looked at the sensational crowd in the audience and showed his white teeth, then nodded solemnly and announced: "That's right, we have come up with wireless remote charging technology." ”
