The logic behind the wireless charging technology applied by Germany's WIFERION, which Tesla acquired, in the modified Model 3 is electromagnetic induction wireless charging. The current modified Tesla Model 3 can achieve a maximum of 12KW wireless charging power, the mostIt's 80 kilometers an hour fast, and it could take about six hours to fill up.
Wireless charging opens up a new charging mode for smart phones, getting rid of the shackles of traditional charging data cables. Although it will be difficult to shake the status of direct charging in smart phone charging for a while, I believe that wireless charging will replace direct charging as the mainstream charging method in the future, and continuous technical optimization will bring users a perfect experience. If wireless charging is not a fire now, it is estimated that it is difficult to fire up in the future.
This technology, which they call "wireless power", has been successfully tested for a two-meter distance60 watt light bulb power. This huge breakthrough quickly promoted the research and application of wireless charging, and soon formed different wireless charging technologies to play a role in different fields.Wireless charging refers to the charger on the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, magical transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. How to use: Connect the USB cable and plug it into the socket.
This water purifier is applied for wireless technical reasonsIt uses electromagnetic wave propagation to convert electromagnetic energy into electric energy and realize remote charging. Electric toothbrushes were the first products to apply wireless charging technology, appearing in the 1990s.
State unchanged direct current, only wire propagation. State changes, such as pulsating direct current, alternating current, etc., can propagate in addition to wires, and magnetic field induction can propagate. Transformers, for example, are not transmitted by wires, but by magnetic fields, which can make the secondary generation of 5 volts.
I have friends who have invented it. But I wanted to see it. I never got to see it. Without wires, electricity has to be converted into other forms of energyHydrogen, for example, is then piped, which of course costs more. Less efficient. When converted into light energy, it's even less efficient. So I don't believe him.
When a radio broadcast is transmitted, most of the energy is scattered in the air, and this technology is to use a non-radioactive field to concentrate this energy. As we all know, electromagnetic waves of a specific frequency will cause vibrations of objects, and two objects with the same natural frequency can transmit this vibration, thus transferring energy. We can have an object, such as a copper antenna, emit electromagnetic waves, which are picked up by a receiver and converted into energy.
Some Samsung mobile phones support wireless charging function, to achieve the function requires a separate charging kit, wireless charging and wired charging effect is the same, but the wireless charging time is relatively longer, no impact on the phone.
The function of chicken ribs, and can not achieve the true meaning of "wireless" : free from bondage. Charging still need to put the phone on the charger, and there is direction, can not lie down ~~. The charging power is small, and the current mobile phone line charge is generally full for 1 hourElectricity, the battery is about 4000MAH. Wireless charging is not so wonderful. It takes four hours to fill up, which isn't great for people who use their phones a lot.
Wireless charging technology still needs continuous development, at present, the wireless charger is not practical, and itself is not convenient, so it needs continuous development and technical improvement.
Most importantly, the cost of wireless charging is not high. QI electromagnetic induction is high school physics, technology has been very mature, add a metal coil to the mobile phone also do not need much money. The phones of Apple, Samsung, Huawei and Xiaomi did not increaseAdding wireless charging adds a hefty price tag. And even Xiaomi's 20W wireless fast charge, the price is less than 100 yuan. In theory, wireless charging technology is safe and harmless to the human body, the resonance principle used by wireless charging is magnetic field resonance, which is only transmitted between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
1, the development of Apple mobile phone canIt is summarized as the process of continuous innovation and gradually establishing market leadership. The development of the iPhone can be traced back to 2007, when Apple launched the first iPhone. The phone revolutionized the mobile phone market with its revolutionary touch screen operation, simple design concept and powerful features.
2, only the development trend of mobile phones in the future: First, the market pattern of brands will be quickly rewritten. Because the highly integrated upstream industry chain means the advent of the era of generalization and standardization, the scale effect will soon overwhelm the cost disadvantage of small and medium-sized brands. Product line will alsoBeginning to streamline, the high-end will already maintain high quality, but the low-end will enter standardization, product level competition will be transferred to brand level competition.
3. Huawei's innovation includes: technological innovation, institutional innovation of "workers own shares", product micro-innovation, and organizational innovation of market and research and development. Technological innovation: Huawei's success in developed markets such as Europe is due to two major architectural disruptive product innovations, one called distributed base station and one called SingleRAN, which is called "sexy technological invention" by Vodafone's technical experts.
4. Jobs led Apple's innovationJobs, with his original innovative thinking, is not limited by traditional frameworks. He didn't set up a dedicated innovation center or system at Apple, but he always set the trend in the tech world. Akio Morita and the birth of the SONY Walkman: Morita noticed that even though portable recorders existed, people still wanted to be able to listen to music whenever and wherever they wanted.
