1. The distance between the transmitting and receiving coils of wireless charging is about 8mm. The QI standard is not just the distance between the two, butIt is the standard of frequency and communication protocol for wireless charging. This distance is a maximum distance, beyond which the efficiency of wireless reception is very low. So it doesn't have to be 8mm.
2, the distance of the wireless charger can only be effective within the coil range of the charger, more than the distance can not receive charging, each manufacturer's product is different, can not be universal.
3, it is the first generation of mobile phone wireless charging, the technology is mature, but can only be single-to-single short-range charging (qi standard, within 1cm, within 5 watts), and can not be similar to WiFi single-to-multiple charging. Over the airThe charging area has a strong electromagnetic field energy, and adding some coils here will induce voltage. The induced voltage can be converted into the energy received by the cell phone battery. Now, the wireless chargers on the market, it is the use of electromagnetic induction technology.
4, the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontally placed in the center of the wireless charger base, you can achieve wireless charging, the indicator light will have a breathing effect, 5 seconds after the extinguish, plug and play, convenient and quick.
5, WiFi wireless charging: ten meters away Advantage: go with charge,In line with the concept of wireless charging disadvantages: charging object positioning is not easy, waste of power Ultrasonic wireless charging: effective range close to 5 meters Advantages: the technology is very safe; The receiver is cheap and small; Can be used for data transmission. Cons: The final product may not live up to expectations in terms of price, power, speed, and safety.
1, the core magnet developed by SpurotinResonant long-distance wireless charging can successfully achieve wireless charging within one meter.
2, currently known reports, the farthest distance is 10 meters, using electromagnetic wave technology. The existing wireless charging technology uses magnetic field, electromagnetic wave, laser, ultrasonic and other energy transfer media. The 10-meter technology mentioned above, which uses electromagnetic waves as a medium, remains 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.
3, in fact, the current technology can reach the range of 3 feet to 4 feetFor effective power transmission, but this also needs to be verified by the relevant organization. I believe that in the next 5 to 10 years, or even sooner, long-distance wireless charging will enter everyone's life.
Wireless charging: the standard protective shell of the mobile phone has no effect on wireless charging. If other protective shells are used, it is recommended to remove the protective shell and then wireless charging the mobile phone. Note: The metal protective shell will interfere with the wireless charging signal and affect the wireless charging function. In order to get a good charging experience,Please use non-metal protective shell. Original protective shell is recommended.
Wireless charging can be used with a phone case. The phone case is not affecting wireless charging. Unless your phone case is very thick, it has isolated the thickest limit of the contact between the charging bank and the mobile phone. In addition, you will not be limited in charging, you can directly charge it, and the charging will be very fast, without affecting the charging speed.
Take Huawei nova5 mobile phone as an example, wireless charging can be done with a phone case, but the phone case will affect the wireless charging efficiency of the phone. Wireless charging requires charging distanceShould be able to do. And this is not the public familiar with Qi wireless charging, is magnetic resonance wireless charging, based on the principle of magnetic resonance. Although there are also 1 meter or even farther wireless charging technology, but the current charging power of these are too small, charging speed is too slow, difficult to put into daily use.
The distance of wireless chargers produced by different manufacturers will be different, generally speaking, effective charging can be achieved within 2 to 3 meters.
1, different manufacturers of wireless charger distance willGenerally speaking, effective charging can be achieved within 2 to 3 meters.
2, the distance of the wireless charger can only be effective within the coil range of the charger, more than the distance can not receive charging, each manufacturer's product is different, can not be universal.
3, does not support long-distance charging, may reach this technology in the future, what is wireless charging technology, according to a report in the United States, there have been research institutions out of the wireless charger can be long-distance, this charger includes a transmitter with a plug, an electronic receiver, as long as the power can be transmitted to the installation within a certain rangeTerminal equipment with a receiver.
4, currently known reports, the farthest distance is 10 meters, the use of electromagnetic wave technology. The existing wireless charging technology uses magnetic field, electromagnetic wave, laser, ultrasonic and other energy transfer media. The 10-meter technology mentioned above, which uses electromagnetic waves as a medium, remains 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.
5, heard that core will launch a radius of about 2 meters next year mobile phone wireless charger. The price will probably be set above 10,000.
6. The core magnetic resonance medium and long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
1. This method is considered harmless to human body, but it must be operated at close range. The new system solves the problem of distance by being made of metamaterials that can manipulate higher frequencies of microwaves in a specific way, ensuring that the electromagnetic field covers all small devices in the entire room, and even extends outside the house for up to 10 meters.
2, you mean thingsPhysical distance or social distance? At the social level, wireless charging of mobile phones has been popularized in high-end products, and there is a high probability that the Xiaomi 8 released tomorrow will also support this function, which is quite close to us.
3, the distance of wireless chargers produced by different manufacturers will be different, generally speaking, effective charging can be achieved within 2 to 3 meters.
4, short charging distance: at present, the effective charging distance of wireless charging of standard mobile phones is about 10mm, so the wireless charger on the market generally needs to put the phone on the wireless charging board and align the position to work effectively. The current charging distance of the magnetic resonance isAbout 5~10cm, the charging distance of electromagnetic waves is about 10 m, in short, the further the charging distance, the lower the charging efficiency will be.
