The distance of wireless chargers produced by different manufacturers will be different, generally speaking, effective charging can be achieved within 2 to 3 meters.
The transmission distance of high-power wireless charging is generally 0.9-2 metersThe 5-meter wireless charging technology can be divided into two ways: low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
①, about the charging induction distance of the above wireless charger, to the wireless charger his [induction distance is generally: 8mm].
-10mm, the best distance is generally 3mm, which is the distance that includes the thickness of the product shell.
At present, the maximum distance of wireless charging is still difficult to determine, shouldElectromagnetic wave as the medium, now stay in the laboratory stage. At present, the commercial technology on the market is mainly magnetic field as the medium, which is divided into magnetic induction and magnetic resonance 2 technologies.
2, the core magnetic resonance long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
3, that needs to be placed next to the transmitter), at the same time, they are also studying long-distance wireless charging, which will be an emerging market. In fact, the current technology can achieve effective power transmission in the range of 3 to 4 feet, but this needs to be verified by the relevant organization. Believe in the futureIn 5 to 10 years, or even sooner, long-distance wireless charging will enter everyone's life.
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.
There is still a lot of space for the development of wireless charging technology, electromagnetic induction is only one of them, in addition, there are theoretical technologies such as magnetic resonance to support the space charging, interested in their own understanding. The mostAfter reminding, if you are using wireless charging, be sure not to put the bus card with chip, bank card, etc. near the wireless charger, it may be degaussed, bringing 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 that the electromagnetic wave signal is emitted through the transmitter (charger), and then the electromagnetic wave is received by the receiving end (electronic device), and the received energy is converted to achieve charging.
Compared with traditional wired charging and wireless charging,There is no need to plug in the cable or touch the charging device, you only need to place the phone near the charging device to charge. This not only improves the convenience of charging, but also avoids the trouble of cable bondage and plugging. At the same time, the air separation charging technology also has a higher charging efficiency, which can fully charge the phone in a short time.
1, its core feature is 20W wireless fast charge, effective induction distanceUp to 4mm away, even if the phone is covered with a protective case, it can be charged quickly. In addition, it has intelligent compatibility and wide versatility, whether you are using Xiaomi Mi 9 Pro, or Apple, Samsung, Huawei and other brands of mobile phones, you can enjoy different degrees of fast charging services. Security performance is also a highlight of the millet vertical wireless charger. 2, generally does not affect, the thickness of the phone case is generally 1mm, which is acceptable in wireless charging, the phone case is generally plastic, it will not affect the charging induction, as long as there is no metal or other conductive materials on the line.
3, the maximum power of millet vertical wireless charger can reach 20W, support wireless fast charging technology, its effective induction distance is amazing, even if the phone is wrapped in a protective case, it can easily complete the charge. In addition, the compatibility of this charger is excellent, intelligent identification of various devices, whether it is Xiaomi Mi 9 Pro, or Apple, Samsung, Huawei and other brands of mobile phones, can enjoy different degrees of fast charging services.
4, can. The Mi 12 case can be charged wirelessly, and the mobile phone's standard protection case has no impact on wireless charging. Xiaomi Technology Co., Ltd. was founded on March 3, 2010, is a companyA global mobile Internet company focusing on the research and development of smart hardware and electronic products, it is also a company focusing on high-end smartphones.
cm. Xiaomi has 19 built-in coils, each of which supports 20W wireless charging, and can choose the right coil according to the placement of the product.
The mobile phone wireless charger is probably about 50mm in diameter of the mobile phone end coil, and the charger end is about 46 to 48mm in diameter, which may be different due to different mobile phone modelsDifference, but the best transmission method is the phone end and the charging end of the coil size is the same.
Coil diameter about 100 mm, wire diameter about 0.5 mm.
1, the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is placed (vertical) or horizontally in the wireless charger base left and right center position, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
2, the mobile phone standardThe charger and the data cable are connected to the wireless charger, and then the phone is placed in the center position of the wireless charger base, you can realize wireless charging, the indicator light will have a breathing effect, and the lamp will be extinguished after 5 seconds, plug and play, convenient and quick.
3, the mobile phone uses wireless charging, you need to buy wireless charging base or wireless charging back shell can be used. Connect the charger to the wireless charging base, and then place the phone or a phone with a wireless charging back case on the wireless charging base. Remove the holster If the phone's holster is too thick or not the original charging holster, it may affect the charging effect, it is recommended to remove the holsterAfter charging attempt.
The introduction of wireless charging coil distance design is here, thank you for taking the time to read the content of this site, more information about wireless charging coil voltage, wireless charging coil distance design don't forget to find oh in this site.
