Chapter 216: Electricity transmission channel

phone-reading
Bi Ye heard Li Hao's instructions, and he said easily: "After the development was completed, we had a scientific research team to design the drawings of the equipment. They are now experimenting with which components can make a more stable equipment.
Our laboratory only requires performance and does not require component life. But when it comes to industrial production, it cannot be done.
This project uses known components, and its structure is not complicated. After finding the right components, industrial production is not difficult at all. "
When Li Hao heard Bi Ye say this, he felt relieved. Since Bi Ye said so, he has enough confidence that he can complete the preparation for industrialization of this equipment when the ferrous graphene battery is put into production.
The three main scientists of the company have different personalities.
Du Xianyu is steady, and he is not impatient when encountering anything. Bi Ye is careful and good at finding problems from small details. Guo Jianzheng is patient, and even if he does not produce results for a long time, he will carry out many experiments according to his own ideas.
Li Hao asked Bi Ye: "Director Bi, is there a small device? I try wireless charging and experience its advanced level."
Graduation took out a palm-sized box directly from the lab bench. He said to Li Hao, "This is our small charging device. You can think of it as a charging treasure made of iron graphene batteries.
I started preparing experiments with smartphones, but after experimenting, I found that the software and hardware of smartphones and iron graphene batteries do not match at all.
As soon as fast charging is turned on, the circuits inside will be burned. I can only make a power bank by myself. Their charging principles are the same, and this technology is not difficult. After manufacturers get the parameters of the iron graphene battery, they can easily design the conversion circuit.
In fact, it is very simple to make a low-voltage low-current charging device, but mainly to match the iron graphene battery, I did not invest in this direction. "
After Bi Ye finished speaking, he remembered another question and said, "When I introduced the wireless transmission technology just now, I forgot to say a key parameter.
The maximum effective transmission distance of our equipment is 8 kilometers, but the effective transmission distance of this device is directly proportional to the complexity of the equipment.
Our medium-sized equipment has an effective transmission distance of only one kilometer. And this small device, the effective transmission distance is shortened to 80 meters. "
Li Hao said with a smile: "I already guessed that its effective transmission distance must be related to power. The power has dropped sharply, and it should be allowed to maintain the original effective transmission distance. This must not be a law of conservation of energy."
After speaking, he walked to the lab bench to pick up the power bank, and then picked up the small wireless charger.
Li Hao surpassed them, only to see that after plugging the charger into the power supply, the charging indicator of the power bank turned on, and then turned off after a few seconds.
Li Hao said in amazement: "So much time, the charger has been fully charged, or it has failed."
Bi Ye explained: "Its charging speed is so fast. Of course, this small charging treasure does not need a rod of iron graphene battery. Instead, it uses very few parts and the charging speed is of course fast.
We have customized the detailed feedback circuit in detail, as long as the charging capacity of the charged device is less than 30% as long as it is not forced to turn on charging. It automatically sends a signal to the charger and starts to fill up instantly.
When the device is fully charged, it sends another signal. Stop the charger. "
Seeing this charging process, Li Hao thought of another extremely important issue.
Frowning, he asked Bi Ye: "Director Bi, the electromagnetic spectrum responsible for charging transmits electricity to all around.
This will not cause my home to use wireless charging devices. Other people, without my permission, used the receiving end to steal our electricity, which led to a sharp increase in my electricity bill. "
Bi Ye said with a smile: "This problem also bothered me for a long time in the early stages of project development. I have never found a good solution.
For example, like our predecessor Tesla, he envisioned using the ionosphere for global power transmission.
This technology is theoretically possible to succeed, just like the AC technology and radio technology he developed. Many of the techniques predicted are successful.
But one thing that cannot be resolved is how to receive the power after it has been output. Because anyone can install a device, they can receive power from others.
As long as the world's energy does not reach the situation, no one will go to great lengths to make this transmission technology. "
While Director Bi Ye and Li Hao discussed, he activated the screen on the wall and used animation to introduce their solution to this problem in detail.
Li Hao looked at this simple animation. In the picture are two iron towers, one representing a power transmission device and one representing a receiving device.
First, a special electromagnetic wave is emitted by the power transmission device. The two iron towers then establish a connection through this electromagnetic wave.
Later, the transmission tower emitted electromagnetic waves with a blue lightning icon. This is an electromagnetic wave that carries electrical energy.
This blue lightning icon has a peculiar electromagnetic wave. It actually transmitted electricity according to the path of the special electromagnetic wave transmission at the beginning, but did not drive to the side.
After this animation is finished, a second animation is displayed.
A very tortuous total reflection tube is used in the laboratory. A 30 cm diameter channel with a length of 30 meters is arranged at one end of the total reflection tube and there is a wireless power transmission receiver. There are more than ten wireless power transmission receivers outside the total reflection pipeline.
After the experiment started, only the receiver on the side of the total reflection tube received electrical energy. The other receivers did not receive any charging power.
After Bi Ye turned off the animation, he asked Li Hao: "With this simple science popular animation, Li should always understand our solution."
Li Hao nodded and said, "You seem to use carrier wave or composite wave technology. First use a set of electromagnetic waves without energy transmission function as a channel, let the two devices verify each other, and establish a power transmission channel.
This kind of electromagnetic wave that transmits electric energy has a characteristic, it will transfer energy along with the special electromagnetic wave channel established. This solves the problem of device verification. "
Bi Ye confidently said: "We just use this method to solve this problem.
In an unexpected experiment. Find this set of effective electromagnetic waves, which has a property we haven't figured out. It can constrain the electromagnetic waves that carry energy and walk along its path.
But it does not prevent us from using this newly discovered phenomenon to establish device verification through it. In this way, the power can be transmitted to the designated target.
If this technology is not loaded, it is an open type wireless power transmission device. After other receiving devices turn on the public mode, they can freely receive the transmitted power. "
Li Hao saw Bi Ye's eagerness to try, and wanted to understand the deep theory of this phenomenon.
He was somewhat admired by real scientists like Bi Ye. They have a strong curiosity about the world and always want to explore the unknown.
After the establishment of modern civilization, modern civilization reached this level in just a few hundred years. This is inseparable from the push of scientists.
