This article gives you a talk about magnetic resonance wireless charging technology book, as well as wireless charging black technology magnetic resonance technology reading understanding corresponding knowledge points, I hope to help you, don't forget to collect this site. < / p > < h2 > the article directory list: < / h2 > < ul > < li style = 'margin - bottom: 3 px; list-style: none'>1, What is the magnetic resonance charging technology, and what is the difference between electromagnetic induction charging
Now the common wireless charging is the use of magnetic induction charging, magnetic induction charging and magnetic resonance charging between the main areaIn particular, the latter is able to obtain power from the charger over a short distance. This doesn't mean you can charge your smartphone from anywhere in the room, but LG's current technology has a range of up to 7cm, which means you can charge your smartphone next to an MRI charger.
Magnetic resonance is the coupling of energy through the coil, and the transmission of electrical energy is achieved through the current generated by the electromagnetic coil. The key devices for wireless charging are power transmitters and power receivers, namely induction coils, including high-current FPC coils and precision metal coils. FPC has good consistency and flexibility while precisionThe wireless charging standard launched by the er Consortium (hereinafter referred to as the Alliance) has two characteristics: convenience and versatility. First of all, different brands of products, as long as there is a Qi logo, can be charged with Qi wireless charger.
2, Qi is a Wireless charging standard created by the Wireless Power Consortium (WPC), its biggest feature is based on electromagnetic induction technology, strong compatibility, can realize the charging between different brands, different designs of equipment. In addition, the Qi standard also supports multiple devices charging at the same timeThe characteristics of dynamic control charging power and charging protection improve charging efficiency and safety, and bring convenient, efficient and reliable experience for people to charge.
3, Qi wireless charging, in short, is a use of electromagnetic induction principle, through the Qi standard for mobile phones, cameras and other small equipment wireless charging technology. This standard is formulated by the world-renowned organization Wireless Power Alliance (WPC), and has been widely accepted and applied by the industry, including Apple, Samsung, Nokia and other global giants have adopted Qi as the wireless charging standard for their devices.
4, QI technology, using electricityMagnetic induction principle, contact charging; Wireless charging technology, magnetic resonance principle, no contact, range charging. (Since the energy is transmitted between the charger and the electrical device by inductive coupling, the two are not connected by wires, so the charger and the electrical device can be exposed without conducting contacts.) Prior to this, wireless charging technology has been only related to "small" mobile devices such as smartphones and small-size tablets.
1, wireless charging blackThe function of the technical expository topic of scientific and technological magnetic resonance is to arouse the reader's attention and thinking. Exposit topics can vividly reveal the object, in the order of time and space, from the phenomenon to the essence, from the main to the second, some according to the process sequence, some according to the nature of things, function, principle and other order.
2, electric field induction technology Electric field induction technology uses space electric field as the medium for wireless charging of equipment. Simply put, the energy transmitting device and the receiving device can be regarded as the two plates of the capacitor. Under the action of AC electric field, the two plates of the capacitor will have alternating current flow, so as to achieve electrical energyWireless delivery.
3, charging equipment support low voltage power supply, compatible with ordinary USB power supply; Achieve low temperature charging, effectively ensure the use of equipment and battery safety and life. Wi-Po technology is a Wi-Po magnetic resonance wireless charging technology, which uses a high-frequency constant amplitude alternating magnetic field generation device to generate a resonant magnetic field of 78MHz to achieve a longer transmission distance.
4, the use of magnets to charge the device technology. Wireless charging technology, derived from wireless power delivery technology, uses magnetic resonance to transfer charge in the air between the charger and the device, and coils and capacitors are in the charger and the deviceThe technology of forming resonance between devices to achieve efficient transmission of electrical energy.
