Chapter 725 Wireless Charging Technology (more explanations)
[Wireless charging technology] in the real world is a technology that uses magnets to charge devices without using wires at all.

[Wireless charging technology], derived from wireless power transmission technology, uses magnetic resonance to transmit charges in the air between the charger and the device, and coils and capacitors form resonance between the charger and the device to achieve efficient power transmission technology.

It's a technology that looks very nice.

【Wireless Charging】It is not only convenient but also safe. There is no wire-type charger, which completely avoids safety hazards such as electric leakage, and will not bring radiation and harm to the human body and the environment when charging.

Compared with wired chargers, wireless charging has the function of self-stopping when fully charged, which reduces energy consumption and is very power-saving.

[Wireless Charging] It can also automatically recognize the difference in equipment and charging capacity requirements, and carry out intelligent and personalized work.

[Wireless charging technology] has a wide range of applications.

For example, mobile phones, earphones, laptops, etc. in electronic communication products; for example, TVs, washing machines, refrigerators, air conditioners, etc. in smart furniture and household appliances; for example, new energy vehicles, electric vehicles, high-speed trains, etc. ; For example, aircraft carriers and satellites in the military field.

Basically, as long as it uses electricity and needs to be charged, wireless charging can be used.

Another point is that the traditional charger can only charge one device, and has the limitation of the charger model. The charger of each device is different. However, wireless charging can charge all devices, and it can charge multiple devices together. .In the future, wireless charging equipment will be installed in public places, and users can charge at any time without worrying about the situation that the power supply of the device is exhausted and cannot be turned on. It is very convenient to use.

Of course, this is the ideal scenario.

In the real world where Wu Siyuan lives, the development of wireless charging technology is still very slow.

Just because [wireless charging technology] is mainly realized by two devices, one is the charger connected to the power supply, and the other is the "tray" that transfers with the charger, as long as the distance between the device and the tray is within the specified range, Then the device can be charged automatically.

However, the distance between the equipment and the pallet is relatively short at present, and the requirements for the distance are very high.

Although this charging method does not require direct contact between the power and the device, the charging effect is the same as the traditional data cable charging, and there is no difference in the use time.

Take wireless charging for mobile phones, which is currently the most widely used.Mobile phones that can support wireless charging need to rely on the [base] to charge, and this [base] needs to be plugged in.

And the speed of [dock charging] is very slow.

The power of dock charging is generally within 10W, and what's more, it will consume.

In contrast, most mobile phones now have a fast charging function with a power of about 18W.

The mobile phone can be fully charged or rushed to the ideal power value in no time.

But [Dock Charging] is different, your mobile phone must be placed there all the time, charging quietly.

It's not as good as wired charging!

At least it can be used while charging.

Most modern people suffer from [mobile phone addiction]. You can let him not take a bath for a few days, but if you let him not touch his mobile phone for a few hours, he will inevitably feel restless.

I always wonder if anyone called you during the time I was away from my phone!

Actually, you are far less popular than you think!

Although [wireless charging technology] is still developing, the market has introduced near-magnetic field wireless charging technology, and is also developing long-distance wireless charging technology, but in the foreseeable future, the real [wireless charging technology] is still far away .

What is the real [wireless charging technology] in the minds of consumers?
Take the mobile phone as an example.

It just doesn’t need a chassis, you can rush while walking, and you can rush as much as you want [Wireless Charging Technology]!

But to do this, there are many technical difficulties that need to be overcome.

For example, the power conversion loss problem of wireless charging technology, the distance problem of wireless charging technology, and the interference problem of wireless charging technology.

These problems have been properly solved in the technology given to Wu Siyuan by the scientists of the heavenly beings.

For example, the [wireless charging technology] in the real world where Wu Siyuan works has a large energy loss, and the transmission efficiency is not high, which easily causes waste of electric energy.

The conversion rate of wireless chargers can only reach up to 85% at present, and as the distance increases, the loss will be greater.

But at this point, the heavenly people have used composite technology, not only the traditional [electromagnetic induction technology], but also [magnetic field resonance technology], which is composed of an energy sending device and an energy receiving device. When the two devices are adjusted to The same frequency, or resonate at a specific frequency, they can exchange energy with each other.

In this case, the conversion rate of [wireless charging technology] can reach 98%, and it can support long-distance wireless charging, and the power can be adjusted accordingly.

It can be said.

If Wu Siyuan adds controllable nuclear fusion technology after this technology is launched in the real world, fossil energy will be eliminated! Of course, fossil energy, such as petroleum, also has chemical uses, such as making plastics What.

Fossil energy will not really disappear from the stage of history, but the consumption will definitely be greatly reduced.

Those resource countries, one counts as one, will all go to the street!

Even if Wu Siyuan did not simultaneously launch controllable nuclear fusion technology due to some scruples, the combination of this long-distance [wireless charging technology] and solar power generation technology can have a strong impact on fossil energy.

Among other things, the photovoltaic industrial park in the desert can be further expanded.

Because an important difficulty that restricted the photovoltaic power generation industry in the desert before was how to transport the generated electricity.

There are not many places in the desert that need electricity.

If the electricity is sent out through the construction of a large number of grids, this also means more expenses, covering a desert with solar panels, plus the combined cost of the west-to-east power transmission project, a conservative estimate will cost about five trillion US dollars.

This cost is too high.

But it will be different if there is the [wireless charging technology] of the heavenly beings.

[Four-Armed King Kong] has been preliminarily evaluated. If this kind of technical equipment is used to [transmit electricity], the cost will be less than one percent of the construction of the power grid.

According to the estimation of the grid construction cost of 500 trillion US dollars, it is less than 3000 billion US dollars, which is more than [-] billion yuan when converted into RMB.

Compared with the possible output, this amount of money invested is nothing short of water!
And what is the power generation potential of the entire desert?
