Wan 'an Technology (002590) : The participating company Evatran has the qualification advantage through ETL certification, and the charging efficiency of the charging system exceeds 90%.
New three board stocks. The "New third Board" market specifically refers to the Zhongguancun Science and Technology Park unlisted joint stock Limited company entering the agency share system for transfer pilot, because the listed enterprises are high-tech enterprises and different from the delisted enterprises in the original transfer system and the original STAQ, NET system listed companies, so the image is called "new third board". The new third board concept stocks are the Shanghai and Shenzhen stock markets with the above-mentioned new third board marketsIn the relevant stocks.
Ophil (002456) : global infrared cut-off filter head; Core technology of holding flat resistive touch screen; 800 million yuan to acquire 100% of the German investment, the main business of the target company includes mobile terminals, desktop streaming media solutions, its core technology is the self-developed TIVC video compression and decoding technology.
Feida Environmental Protection (600526) : The company is the vanguard of China's atmospheric environment treatment industry, mainly engaged in the development, production, sales, installation and other engineering services in the fields of electric dust removal, flue gas purification, pneumatic conveying, etc.The current, thereby transferring energy from the transmitting end to the receiving end.
Technology that uses magnets to charge devices. Wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transmit charge in the air between the charger and the device, and the coil and capacitor form resonance between the charger and the device to achieve efficient transmission of electric energy technology.
1, wireless charger refers to the charger that does not use the traditional charging power cord to connect to the terminal device that needs to be charged, using the latest wirelessCharging technology, through the use of magnetic fields generated between the coils, magical transmission of electrical energy, inductive coupling technology will become a bridge connecting charging base stations and devices. 2, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
3, wireless charging is also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, is the use of near-field induction, that is, inductive coupling, by the power supplyThe standby (charger) transmits energy to the electrical device, which uses the received energy to charge the battery and at the same time for its own operation.
4, mobile phone wireless charging refers to the charger and the electrical device between the two can charge the mobile phone without wire connection.
5, Nikola Tesla invented the "Tesla coil", opened the door to the era of wireless power transmission. Wireless charging market has great potential in the future, not only mobile phones, but also a variety of digital, smart home, automotive and other fields can be developed, so it is very important.
6, finally realize wireless chargingElectricity. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, and ZTE's electric vehicle wireless charging uses induction mode. High-power wireless charging usually uses resonance (most electric vehicles are charged this way) to transfer energy from the power supply device (charger) to the electrical device. The device uses the received energy to charge the battery and at the same time provide energy for the battery's own operation.
1, wireless iPhoneCharging uses the principle of electromagnetic induction. What is the principle of wireless charging for Apple mobile phones? The principle of wireless charging technology is actually the principle of electromagnetic induction. Children who have learned high school physics, I believe that everyone is very clear that electromagnetic waves have energy, can be obtained through the electromagnetic coil, and then the coil will form a current, and finally through the integration of the circuit can be charged.
2, the above is the schematic diagram, the principle is the principle of electromagnetic induction.
3, first you need to have an Apple phone that supports unlimited charging, such as iPhone X, iPhone iPhone PhoThen you need to buy wireless chargers from formal channels, and it is recommended to buy them from APPLE official dealers. Then power on the wireless charger, make sure there are no magnetic objects around before connecting the power. Then place it in a flat place to prevent the phone from slipping off it.
