Chapter 532: Power wireless remote directional transmission technology
New technology? Everyone in the audience couldn't help but become curious.
Wu Hao and his team’s technological breakthroughs in battery energy have always been outstanding, and the launch of several major technologies has shocked the world.
So what is the new technology Wu Hao is talking about this time? Everyone is looking forward to it.
Wu Hao, on the other hand, looked at the people in the audience and continued unhurriedly: "Because the space available on the entire pair of glasses is very limited, we can only make fuss about the hollow space in the limited frames and temples.
.
In addition to installing a large number of electronic components, there is very little space reserved for batteries. Although the latest super solid-state batteries cannot be used, we have developed a new generation of commercial batteries based on the original new lithium batteries. This battery has
Each performance 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 inside is small, it reaches an astonishing 800 mAh."
Oh, bang bang bang bang... After everyone in the audience saw the data on the big screen, they couldn't help but cheer and applaud.
In addition to some booing specially invited fans, the professional media and guests in the audience also couldn't help but nod in admiration. It is really amazing that an 800 mAh battery can be installed in such a small space.
"No more. If it's too much, it won't be able to fit, and the weight will increase, which will affect our wearing experience. Everyone will feel tired after a long time.
Therefore, after repeated experiments, we set it at the balance compromise point of 800 mA.
Is there any room for upgrade? In fact, there is. It’s just that we use it to place other components. It also has a crucial impact on the battery life of this smart AR glasses.
Why do you do that?"
Wu Hao asked a question, then paused to give everyone some time to think, and then continued: "Because the power of this smart AR glasses is relatively high, simply put, it consumes too much power. Even if it is equipped with these 800 millimeter
The battery can only support its operation for six and a half hours.
Why it consumes so much power is mainly because of its transparent display screen, as well as the power consumption of various lens sensors and other components all over it.
The first is the transparent display screen. In order to have sufficient display brightness and color saturation as well as high-definition image quality and ultra-high refresh rate, it consumes a lot of power. It can be said to be the leading power consumer in the entire device.
Then there are these lenses. Unlike the mobile phones we use, these lenses must be working all the time, so they consume more power.
Anyone who knows a little bit knows that taking photos with a mobile phone or camera consumes the most power.
So even if we equip this smart AR glasses with an 800 mAh battery, it still cannot meet its long-term use.
Of course, under normal circumstances, six and a half hours of battery life is already excellent and can meet our most basic usage requirements.
But……"
Wu Hao emphasized, then shook his head and said: "I'm not satisfied because it's not perfect enough. 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 the beautiful appearance and wearing experience and adding a larger, heavier battery with longer battery life.
Or, set an interface on the temple part of the smart AR glasses, and then use a part similar to a headphone cable to connect to another power supply device for continuous power supply.
This solution is good, and it doesn’t need to change the appearance and weight of the smart AR glasses, but it does add an extra wire, which is very troublesome and annoying. I don’t like it, so can this wire be removed?”
How is this possible? This was the first answer that came to the minds of the vast majority of the audience who heard Wu Hao's question. As for a small number of people, their eyes lit up and they stared at Wu Hao, looking forward to what he would do next.
Answer.
Wu Hao, as for Wu Hao, did not keep everyone waiting, but nodded with a smile and said: "In fact, it is possible. The wireless charging technology that we have widely used in daily life can meet this requirement.
But someone asked, the current wireless charging technology is to charge close to objects, what is the difference between this and plugging in a wire? The problem still has not been solved."
In a different tone, he continued: "It does not solve the fundamental problem, but it provides our engineers with a solution, that is, can we develop wireless charging technology that can perform remote charging."
"Remote charging?"
"Wireless charging technology?"
"crazy?"
"How can this be……"
The audience immediately became noisy, everyone was whispering among themselves, obviously shocked by Wu Hao's statement.
Not only the live audience, but domestic and foreign viewers who were watching the live broadcast also started arguing. For a while, various live broadcast rooms, forums, communities, and even social software were discussing this issue.
But Wu Hao didn't give everyone much time to discuss. Instead, he pressed his hand to calm everyone down and said with a smile: "Yes, when this plan was first proposed, many people were shocked.
Everyone felt that this was completely impossible and could be said to be a fantasy.
But I like this plan very much because it is creative enough, and I don’t like to challenge what everyone says is impossible.”
"In fact, the principle of wireless charging technology is very simple. There are currently several relatively mature technical solutions, such as electromagnetic induction type, electromagnetic resonance type, radio wave type, electric field coupling type, etc.
However, these wireless charging technologies have a common problem, that is, they cannot achieve long-distance power transmission, or the loss during the long-distance transmission process is too large to meet practical requirements.
There are many reasons why this is the case, the most important of which are that the power of the transmitter and receiver is too low, the electromagnetic wave dispersion is not concentrated enough, etc.
Our R&D team, together with our battery and energy power research laboratories, worked together to overcome many difficulties and finally overcame this technical problem and developed power wireless remote directional transmission technology."
Huh! This time the noise in the audience was louder than before, and it was the same on the Internet.
The live broadcast media immediately reported it in bold font on the front page of the website, with the title "Haoyu Technology releases major scientific and technological achievements, wireless remote charging technology turns out, and may change the entire world."
Wu Hao, who was standing on the stage, looked at the crowd in the audience and showed his white teeth. Then he nodded solemnly and announced in a loud voice: "Yes, we have developed wireless remote charging technology."
