Lee Dong Hyuk is very interested in this very complex magic circle, as a layman who doesn't know much about these things, Lee Dong Hyuk always feels that the more complex the pattern and the larger the inscription, the more powerful this thing is.

Because this is also true in traditional fields, such as large hydraulic forging machines, or keel machine tools and the like. These are all huge and technically complex.

There is an old saying that a big man is beautiful. This is not unreasonable. In terms of human aesthetics, almost everything that is huge will give people a complex and beautiful feeling.

Lee Dong Hyuk already had a lot of conjectures about this large magic array in his mind. What the hell is this thing for?

Could it be the so-called teleportation magic that often appears in his son's watching anime?

It would be great if there was a teleportation magic array, and it is quite important for a big country like China to solve the transportation problem, even if it can't solve the long-distance traffic. It is also good to be able to solve the short-distance traffic in the city.

Just when Li Donghyuk was thinking about it, Zhang Tong smiled over there and said, "This is a large charging pile." ”

"What?" Lee Dong-hyuk didn't react for a moment.

"Large charging pile. To put it simply, this is a super-large wireless charging device, which is used to charge these flying swords. ”

Li Donghe was a little incredulous, looking at this huge magic array, his hand trembled and pointed: "This is a charging pile?"

This disappointed Lee Dong-hyuk, because this thing looks quite advanced, but it seems to be very low-functional.

It's a bit disappointing that something that looks so advanced is just a charging pile.

Zhang Tong obviously noticed Li Donghyuk's disappointed expression, this is not a good phenomenon, he still has to fool Li Donghyuk, cough cough, he still has to get some reasonable investment from Director Li.

So when he saw Li Donghyuk's disappointed appearance, Zhang Tong immediately said that this magic array was more unusual.

"Director Li: Although this is a charging pile, it is not just a charging pile. In fact, we returnees have done some research and improvement on modern technology. ”

Zhang Tong exerted his eloquence as much as possible, because in his opinion, this is his most important foundation, and a martial artist who can't talk cannon in this era can't become a good chef.

"I know that electricity is the most important energy source in the world right now. I see that many cars on the road now start to use electricity instead of burning gas. But for charging, it's actually quite troublesome. ”

As a chef with a deep research foundation in electricity, Zhang Tong actually has some research on electricity.

He had bought some electronic equipment from Taobao before. Although it is said that he first engaged in these electronic equipment, it was not for the purpose of studying magic arrays or anything.

However, with the help of Zhang Tong, the two groups of returnees, immortal cultivators and magicians, have become more and more adept at how to recharge.

Although the magicians of the Wizards Guild did consider the use of electricity to supply various magic arrays in the past, their conversion ratio was not very high. And the conversion speed is also slower.

When Zhang Tong became the leader of this association, he considered the basic way out for his subordinates.

He was secretly making a little effort. When the immortal cultivators and magicians didn't pay attention, they quietly helped them improve some small details about the magic circle charging project.

And Daoist Wang and Master Xiao thought that those flashes of inspiration were the result of their efforts with their members.

Just like the large passenger flying sword, it can fly at such a high speed, carry 40 passengers, and count 10 kilometers round trip. It only needs a quick charge and can be fully charged in 15 minutes.

This is quite a powerful fast charging technology.

Zhang Tong quietly uses his power to change the products of the Returnee Mutual Aid Conference, which will also improve the living conditions of these association members, and will also help improve the technology of the world.

Because now this world. In fact, there is still a very, very large amount of electricity.

But fast charging is actually a serious problem. Whether it's mobile phone charging or car charging, this has always been a very big problem.

Among the applied science and technology, fast charging has always been a popular project for venture capital.

For example, for example, the most criticized thing about electric vehicles is power anxiety caused by insufficient battery life.

And a very important reason for this anxiety is that charging is not like refueling. Refueling, just drive the car to the gas station, and a few minutes will solve all the problems. Fill a tank of gas and hit the road.

And if an electric car is depleted, it will not be fully charged in three to five minutes. Basically, it takes several hours to do it.

It is also because of such a long charging time that electric vehicles have become a means of transportation that many people do not consider at all.

In fact, now the better electric vehicles in the market can already achieve a range of three to five hundred kilometers. This range is not much of a disadvantage compared to conventional cars.

The most important problem of electric vehicles is that fast charging cannot be solved, if you need to use the car temporarily and the car is out of power, it will be very embarrassing.

"All of our flying swords are recharged. Director Li, you can take a look. Although the flying sword is restrictive and has quite high requirements for the consumer, it is necessary to reach at least LV level 1 and use this rechargeable flying sword with auxiliary energy to fly. ”

"But from a certain point of view, it can meet the needs of three-dimensional transportation. And a large charging pile like ours is particularly easy to use. It can charge 100 solo flying swords at the same time. It only takes 20 minutes to charge a single flying sword to reach a range of 200 kilometers. ”

Zhang Tong said these data seemingly indifferently, as if he was trying his best to sell his flying sword plan to Director Li.

But Director Lee Dong-hyuk thought about it and said, "Wait, are you saying that you can fully charge a flying sword in 20 minutes, so that they can fly 200 kilometers? How many kilowatt-hours can you charge it in 20 minutes?"

"The flying sword still consumes more electricity, and it can probably give the flying sword about 100 kilowatt-hours of electricity in 20 minutes. Zhang Tong reported one such data.

100 kWh can only last 200 kilometers. This is actually very energy-intensive. However, considering that the flying sword needs to fly in the air, and it also needs to be equipped with various magic circles, this consumption is still acceptable.

However, Director Lee Dong-hyuk heard something else: "Can you fully charge a Tesla in 20 minutes?" As the current leader in the electric vehicle industry, Tesla is the benchmark for almost all electric vehicles, and its battery capacity is 85 degrees Celsius and has a range of more than 400 kilometers.

"That's right. Zhang Tong smiled, his smile was very honest, which made people feel very relieved at first glance.

Lee Dong Hyuk slapped his face: "Chairman Zhang, can your fast charging technology be applied to other power fields? ”

"If it can be used in other industries, whether it is automobiles, aircraft, ships or industrial manufacturing. As long as this fast charging technology can be applied, then I can tell you here that I can directly grant you the amount you want to apply!"

So far, Lee Dong-hyuk has not seen the garbage sorting array, but this charging array alone is enough to make him make up his mind to invest, of course, this charging array must be something that can really work and not be a piece of paper.

In the field of new energy vehicles and new energy vehicles, the country has invested a lot of money. Even the prime minister of a country has been fooled. After seeing the real new energy vehicles in Toyo, he was angry and cut all the previous new energy subsidy projects in China. Because those who don't fight are all cheating subsidies.

Whether new energy has a head or not, it is natural that there is a head, but the technology is not up to par and is not mature.

And if Zhang Tong's fast charging technology can really be applied to these aspects, then maybe overtaking in corners will really be successful. At that time, Tesla was waiting to sell cabbage at a price, or it would go out of business.

After all, in many cases, as long as a product is made Chinese, then the global price will fall in response. It's like a balance bike that was all the rage in the past. The price of one is seven or eight thousand yuan, and after the appearance of the Xiaomi balance car, the price of the balance car has dropped to 2,000 yuan. And now, the balance cars of three or five hundred on Taobao have been seen everywhere.

And Zhang Tong didn't seem to know Li Donghyuk's thoughts at all, he just grabbed his hair and smiled innocently: "Is there such a big business opportunity here?"

Lee Dong-hyuk shook his head: I'm still an honest man.
