Today to share with you the knowledge of the principle of wireless charging, which will also explain the wireless charging project, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>Simply put, the wireless charger is actually a charging mode that relies on the energy of electromagnetic waves to convert electromagnetic waves into electrical energy.
Wireless charging technologyThere is still a lot of room for development, electromagnetic induction is just one of them, and there are theoretical technologies such as magnetic resonance to support the space charging, interested in their own understanding. Finally, if you are using wireless charging, be sure not to put the bus card with a chip, bank card, etc. near the wireless charger, which may be degaussed and bring unnecessary trouble.
Wireless space charging technology is a wireless charging technology that enables electronic devices to achieve wireless charging technology through electromagnetic induction, magnetic resonance and other principles without plugging wires. The principle is to transmit electromagnetic wave signals through the transmitting end (charger), and then receiveLevel spatial positioning, accurate detection of mobile phone location. A phase control array of 144 antennas transmits millimeter waves to the phone through beamforming. On the mobile side, Xiaomi has self-developed the miniaturized design of the antenna array, with built-in beacon antenna and receiving antenna array.
Xiaomi's air separation charging technology is actually realized by relying on the air separation charging pile developed by Xiaomi. Its built-in 5 phase interference antennas can conduct millisecond spatial positioning of the mobile phone and accurately detect the position of the mobile phone. The phase control array composed of 144 antennas can transmit the millimeter wave to the mobile phone through beamforming, and the mobile phone passes the micro beaconThe antenna receives, and then realizes 5W long-distance charging within a few meters.
October 29, Lei Jun in the personal public number announced that millet officially released the space charging technology, and took the lead in the millet 11 to achieve in Lei Jun's personal micro blog, he disclosed the principle of millet space charging technology, is to install a space charging pile in the room, the mobile phone through the micro beacon antenna to receive the millimeter issued by the charging pile.
Yes, January 29, millet technology founder Lei Jun announced on social media, millet officially released the space charging technology, can achieve a single device 5 watts long-distance charging. Lei Jun is on social mediaThe body said that the air separation charging technology is mainly achieved by millet self-developed air separation charging pile.
A: The role of space charging just place a space charging pile in the room, holding the mobile phone into the room can achieve space charging. In the space within a few meters of the radius of the air charging pile, the power of 5W can be achieved. Not only does it support charging in a static state, but you can also keep charging while holding the phoneElectricity. Even if there is a foreign body between the phone and the air charging pile, it will not affect the air charging.
The technical principle behind millet wireless wireless charging is physical electromagnetic induction. The so-called electromagnetic induction principle refers to the part of the conductor of the closed circuit in the magnetic field to cut the movement of the magnetic induction line, the conductor will produce current, this phenomenon is called electromagnetic induction phenomenon. The current generated by electromagnetic induction in the closed circuit is called induced current. It is the inductive current that replaces the alternating current transmitted by the power adapter to complete the mobile phone charging process.
From the official information released by Xiaomi, just in the roomPlacing a space charging pile, looks a bit like an air humidifier and other household appliances, holding a mobile phone into the room can achieve space charging in the space within a few meters of the radius of the space charging pile, can achieve power up to 5W space charging not only supports the static state.
What principle of millet 11 space charging: The technical principle of space charging is released from the energy source, there is a fixed frequency of radio waves and mobile phone receiving frequency match, so as to transmit electric energy and charge. Due to the power loss efficiency of this technology is about 70%, but the stable power of 5 to 10w is already the limit.
1, space charging technology is actually a wireless charging technology. Wireless charging technology is a technology that uses non-physical contact to achieve power transmission. At present, there are three common wireless power transmission technologies, respectively: electromagnetic induction: the working principle is: install the transmitter coil on the wireless charging base, install the receiving coil on the back of the mobile phone, when the mobile phone is near the charging seat to charge, the transmitter coil will generate alternating magnetic field due to access to alternating current.
2The principle of empty charging is to install the transmitter coil on the wireless charging base and install the receiving coil on the back of the mobile phone. When the mobile phone is charged near the charging base, the transmitting coil will generate alternating magnetic field and induced current due to the access of alternating current, thus transferring energy from the transmitting end to the receiving end and completing the charging.
3, mobile phone space charging is the electromagnetic induction form of the transmitting device has a transmitting coil, the receiving device has a receiving coil, through the electromagnetic induction between the two coils of energy transmission principle is through electromagnetic conversion, to achieve the purpose of the transmission of electricity in the space mobile phone space charging device is a ROHS requirementsThe wireless charging and transmitting scheme is adopted.

5, the principle of wireless charger Wireless charger is a device that uses the principle of electromagnetic induction to charge mobile phones. At the sending end and the receiving end, the wireless charger has a coil. Send a single coilThere is an electromagnetic signal sent, and the receiving single coil can receive the electromagnetic signal sent, and then the electromagnetic signal is converted into current, and the current enters the mobile phone, so as to achieve the effect of wireless charging.
