Chapter 42： Wireless power transmission technology

Chapter 42 Wireless Power Transmission Technology

As these automobile industries and related manufacturing industries are paying attention to He Xingzhou’s next live broadcast, He Xingzhou is studying wireless charging technology with the research team in the institute.

Their wireless charging is not short-distance wireless charging for portable electronic products like mobile phones, but a more powerful technology to charge metal air-powered batteries.

He Xingzhou envisions that his electromagnetic floating car can be charged in a variety of ways.

One is the most traditional, using charging piles for charging. This will undoubtedly reduce the efficiency of logistics and transportation, so the improvement plan includes replacing the battery cell. As long as the battery cell of the metal-air battery is replaced, it takes less than ten seconds to make the battery "full of blood and resurrection"!

They can do both of these methods, but He Xingzhou is still not satisfied.

He hopes that maglev vehicles can be fully and seamlessly charged, which is high-power wireless charging technology.

"It consumes 100 units of energy and has unlocked short-distance wireless power transmission technology." On the technology tree, He Xingzhou unlocked this technology.

In this technology, there are medium-distance, long-distance, and even ultra-long-distance energy transmission technologies that take light years as the distance.

For example, the use of "waves" such as light to transmit energy and so on. This kind of technology is also a kind of energy transmission technology needed to build the Dyson ball in the future.

He Xingzhou unlocks the short-distance energy transmission using electromagnetic field energy.

After absorbing and mastering this knowledge, He Xingzhou held a research meeting.

"Everyone." In the meeting room, there are power engineers and scientists, most of whom come from the National Grid and the Institute of Electricity and Electromagnetism.

"I think that since the maglev vehicle needs to be laid with magnetic materials on the road, we can further transform the road magnetic materials." He Xingzhou took out his own design plan and showed it to everyone.

"As early as 1890, Nikola Tesla did a wireless power transmission experiment. He once imagined using the earth as the inner conductor and the earth’s ionosphere as the outer conductor, and by amplifying the transmitter in a radial electromagnetic wave oscillation mode, A low-frequency resonance of about 8 Hz is established between the earth and the ionosphere, and the surface electromagnetic waves surrounding the earth are used to transmit energy."

"This idea was too avant-garde. Although it could not be completed, later scientists calculated from theory that if a free-space waveguide beam is used, a transmission efficiency of nearly 100% can be achieved."

"What I envision now is to lay a layer of equipment on the magnetic road surface, which can make the magnetic field between the electromagnetic float and the road resonate. This section of the road is connected to the power grid and transmits electrical energy to the electromagnetic float in the form of electromagnetic field resonance. The wireless power receiver converts it into electrical energy and then stores it in the battery."

"In this way, our maglev car does not need to stop to charge or change the battery! It can be charged while driving, maximizing logistics efficiency!"

At this time, no one responded to his words, because all the experts were reading the materials he distributed, which read "Design Scheme of Short-distance Electromagnetic Coupling Induction Wireless Power Transmission System".

It took a full half an hour before someone continued to speak.

"From a theoretical analysis, there is no problem at all!" An electric power expert muttered to himself.

"We have been researching wireless power transmission technology, but it is based on electromagnetic waves that transmit microwave energy and convert it into a small amount of electric energy. This kind of electric energy can only fully charge the battery of the mobile phone. The wireless power transmission power in Mr. He's plan is at least It's a thousand times ours!" The engineer of the power grid was shaking with excitement while holding the project file.

"According to this plan, not only can we make wireless power transmission between the road surface and the electromagnetic floating car, but also can make a short-distance wireless power transmission device!"

“In some special areas of our country, laying wires and power grids is very troublesome. If we design a wireless power transmission tower based on this technology, wouldn’t it reduce us costs by more than 80%?”

These experts have begun to think divergently, thinking of various application scenarios of this technology.

"Yes, once this technology is promoted, traditional electric vehicles can also be used. There are other electronic products that can be fully extended to family life if their safety performance is guaranteed."

"In a residential community, you don’t even need to sign wires. To build a wireless power transmission tower in the community, you only need to install a wireless power receiving device at home to have electricity!"

"All electrical appliances and smart devices will be changed as a result! Become more convenient and easy to use!"

……

The more they talked, the more excited they were, and they even began to discuss how to build a nationwide wireless power transmission network.

He Xingzhou smiled, this was the effect he wanted to achieve.

The manufacture of electromagnetic floats is only a phased goal. In the process of reaching the goal, the various technologies developed are his real goal.

These technologies can be used in all aspects to drive the overall technological progress of the entire country!

"Ahem." He Xingzhou interrupted their discussion and said, "Everyone, please don't get too busy."

"This short-distance wireless power transmission is still not up to the level of building a power grid, and safety and the like need to be studied and improved."

"You can continue to study in depth, but before that, we have to do a section of the laboratory wireless charging magnetic road."

"Yes, yes, yes! You can't be fat with one bite. Let's get the wireless charging of this electromagnetic floating car first, and it will be a technical reserve for us to build a national radio network!"

They reminded He Xingzhou that the construction of a wireless power transmission grid across the country should be added to their plan! Even the planetary radio network that surrounds the entire earth!

I have to unlock the medium-distance wireless power transmission technology, and then discuss with the Xuanwu executives.

Everyone accepted their hearts and began to carefully analyze and discuss how to charge the electromagnetic floating car during driving.

"It is unrealistic to pave the charging road on all roads, and the cost is too high. We can set a certain stage as the charging road. When the electromagnetic float enters the road section, the charging state will be automatically turned on, and a charging protection mode will be installed to ensure all kinds of safety. facility."

"If it is a thunderstorm, will the charging be disturbed by the thunderstorm, should you stop charging?"

"How to avoid a single vehicle accident that affects the charging of other electromagnetic floating vehicles on the road or on the road?"

……

Even if they have the technology, they have to make a complete plan to implement it.

At the same time, in the unmanned driving technology group, researchers are also improving the unmanned driving system.

At present, unmanned driving technology is divided into L0 (no automatic driving); L1 (driver-assisted driving); L2 (partially automatic driving); L3 (conditionally restricted automatic driving); L4 (highly automatic driving) and L5 (Fully automatic driving) Six levels.

The experts in the He Xingzhou team, combined with their existing research results, have been able to achieve L4 highly automated driving.

There is still a gap between L5 fully automatic driving, but L5 level fully automatic driving on electromagnetic floating vehicles is easier than traditional cars.

Because the electromagnetic floating vehicle must currently drive on magnetic roads, which isolates many complex driving scenarios; its speed, regulation, etc., make it necessary to be integrated into the intelligent transportation network for unified control. In this way, the electromagnetic floating vehicle is realized. L5 autonomous driving has become the simplest research in this project, but it does not require He Xingzhou's personal participation.

Everything is going on tensely and orderly, He Xingzhou’s electromagnetic float is about to come out!

Thank you for the reward of your Royal Highness Bubble Teapot and Crimson Wind.
