The special envoys have seen the work of this [wireless magnetic field resonance electric pile] with their own eyes. Huang Yuping did not lie. This is like a charging pile, which can transfer electricity without going through traditional wires.
However, what the envoys observed was that wires were needed to introduce electricity at the input end, and wires were also needed to output electricity at the output end.
Can’t you directly wirelessly charge electricity into various devices?
A special envoy asked this question, "This technology of [Chaoqun Group] can only be used to transmit electricity, and cannot be directly used for wireless charging?"
"Of course we have taken this into consideration and started research. However, due to some technical difficulties, we can currently only support wireless charging of low-power electrical devices. These electrical devices that support wireless charging must also have specialized
Resonance control core chip and induction coil." Huang Yuping explained.
"The induction coil is used to generate frequency resonance, and the resonance control core chip is the resonance principle control center of wireless charging technology, which is very important. Precise radiation range control, magnetic field frequency size, and other controls are all implemented by the chip."
Several envoys listened silently.
Huang Yuping added, "I know what the leaders are saying. They want to ask if this technology of our group can support cars or other large-scale electrical equipment, and it can be used while charging, right?"
"It's a pity that it's not possible yet! But the research and development of mobile phone charging while using is already underway." Huang Yuping shook his head and said.
Several special envoys were a little disappointed when they heard this.
If [Chaoqun Group] really develops wireless charging technology that can support large-scale electrical equipment such as cars while charging in real time, then the domestic new energy vehicle industry will usher in truly explosive growth.
Despite the rapid development of new energy vehicles, in fact, the gap with fuel vehicles is still huge.
For the whole year of 2021, the cumulative sales volume of domestic automobiles was 26.275 million units, a year-on-year increase of 3.8%. In the passenger car field, the cumulative sales volume for the whole year of 2021 was 21.482 million units, a year-on-year increase of 6.5%. Among them, the growth rate of new energy models was the most obvious, with 2021
The cumulative sales volume for the whole year was 3.521 million vehicles, a year-on-year increase of 157.5%.
The data on new energy vehicles seems to be very good, but looking at the specific values, in the field of passenger cars, in 2021, the sales volume of new energy vehicles was 3.521 million units. The sales volume of non-new energy vehicles, that is, traditional fuel vehicles,
Reached 17.961 million vehicles.
The difference between the two is as much as 5 times.
If the new energy automobile industry wants to replace the traditional automobile industry, it can only be said that there is still a long way to go.
There is of course a reason why the higher authorities attach so much importance to and vigorously develop the new energy automobile industry.
The first is to reduce dependence on imported oil.
Our country is a country "rich in coal, short of oil, and short of gas". However, my country, which is short of oil, is the world's second largest crude oil consumer and the world's largest crude oil importer.
In recent years, the gap between my country's oil production and consumption has continued to expand, and the gap can only be filled through oil imports.
As the world's largest oil importer, my country's oil import volume growth has remained at a high level for many years, and its dependence on oil imports has reached more than 70%.
At the same time, my country's coal reserves rank among the top in the world, and the current power grid is dominated by "coal power". The development of pure electric vehicles can solve the problems caused by "lack of oil and gas", so it is the country's "leverage to leverage strengths and avoid weaknesses" Considered results.
As a secondary energy source, electric energy is not limited by petroleum resources. In addition to coal, nuclear energy, wind energy, hydropower, solar energy, tides, and geothermal energy can all be used to convert into electric energy. Therefore, strategic security will be greatly improved.
Second, the energy utilization rate is higher.
Traditional automobiles rely on internal combustion engines to convert the chemical energy of gasoline and diesel into kinetic energy. However, the thermal efficiency of internal combustion engines, that is, automobile engines, is only 20% to 40%. Coupled with crude oil mining, refining, processing and other processes, the average energy utilization rate of crude oil is only
About 14%.
Relevant data shows that even if heavy oil is used to generate electricity, and then the electricity from the power plant is output (during which it goes through heavy oil refining, power plant thermoelectric conversion, power transmission, battery charging and discharging, motor loss, etc.), the motor output shaft of the electric vehicle can also
About 20% of the energy is obtained. If instead of using heavy oil to generate electricity, other power generation methods are used, the energy utilization rate will be higher.
Relevant calculations show that if electric energy converted from new energy sources is used, pure electric vehicles can save up to 70% more energy than fuel vehicles, and can also save about 50% in costs.
The third is green, low-carbon and environmentally friendly.
In the last 20,000 years when human civilization was born and the population increased dramatically, the global temperature was very stable. The fluctuation was about one degree. But now human activities have caused the temperature to rise by 2 degrees by 2050 and by 4 degrees by 2100.
The trend is changing.
Such a drastic change in temperature is likely to bring unprecedented disaster to mankind!
So environmental protection is indeed something worth considering.
It's just that China didn't develop in the past, so we kept silent about environmental protection and the so-called carbon emission rights.
After all, environmental protection is of paramount importance, and it is not as important as having enough food for the Chinese people.
But now that domestic development has reached a certain stage, and after the emergence of the new energy vehicle industry, the country has seen new opportunities, carbon emissions and environmental protection can also be discussed.
Another important reason why my country is vigorously developing the new energy automobile industry is that our country has great advantages in new energy.
my country is much richer in resources in the electric vehicle industry chain. The core technologies of electric vehicles are "battery, motor, and electronic control", and my country has very abundant reserves of the two key resources required for the production of batteries and motors.
At present, most of the main power batteries for electric vehicles are lithium batteries, and my country is also the third country with the world's largest lithium resource reserves. As for motors, electric vehicles currently generally use permanent magnet synchronous motors, which require the use of rare earth permanent magnet materials to make the rotor of the motor. my country's rare earth resource reserves rank first in the world, accounting for half of the world's total reserves. In the current rare earth product market, my country's output accounts for more than 90% of the world market. Therefore, in terms of resources, my country has a natural advantage in developing electric vehicles. .
New energy vehicles have allowed the country to see an opportunity to overtake in the automotive field. Otherwise, given the current domestic situation, it would be difficult to compete with established foreign car companies that have been immersed in this field for dozens or hundreds of years.
A large number of patented technologies are in the hands of these foreign car companies. The more domestic cars are sold, the more foreign car companies are actually making money.
Just like the VCD industry in the past.
Because they did not master the core technology, foreign movement manufacturers joined forces and used patents to harvest them.
Finally, it was discovered that domestic factories assemble a VCD worth several thousand dollars for sale, and the profit earned on the last one is less than $2.
