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.
is generally 0.9-2 m leftRight high-power wireless charging transmission distance up to 5 meters Wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways. 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.
The core magnetic resonance medium and long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter. The WattUp Mid Field transmitter, developed by SAN Jose startup Energous, is a long-range wireless charging systemIt can charge devices up to 3 feet away. This is a significant improvement over current smartphone wireless chargers, which require the device to be in direct contact with the charger, limiting utility.
Non-contact inductive charging is the use of near-field induction, that is, inductive coupling, by the power supply device (charger) to transmit energy to the power device, the device uses the received energy to charge the battery, and at the same time for its own operation. The advantage of wireless charging technology is that it has high technical content, easy operation, and can implement long-distance radio energy conversion, but high-power wireless chargingM?? '> What is the maximum distance of the wireless charger??
Generally about 0.9-2 meters high-power wireless charging transmission distance up to 5 meters wireless charging technology can be divided into low-power wireless charging and high-power wireless charging two ways. 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.
The core magnetic resonance medium and long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
Currently known reportsThe longest 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.
The current wireless charging technology can only reach a maximum transmission distance of 7 meters.
The distance of the wireless charger can only be effective within the coil range of the charger, and the charge cannot be received beyond the distance, and each manufacturer's product is notSame, can not be generalized.
1, the wireless charger distance produced by different manufacturers will be different, generally speaking, within 2 to 3 meters can achieve effective charging.
2, Do you mean physical 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, generally about 0.9-2 meters of high-power wireless chargingWireless charging technology can be divided into two ways of 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.
4, we often say that wireless charging actually has great limitations, the effective distance is generally only 8 mm -15 mm, in this range can be normal wireless charging, the so-called space is separated by a mobile phone shell empty only. If there is a metal interval, it will affect the normal charging.
5, hear coreNext year, Kotai will launch a mobile phone wireless charger with a radius of about 2 meters. The price will probably be set above 10,000.
6, the effective charging distance is 0cm, just do not use the line. Wireless charging is a special metal plate added to the back of the phone, which can be charged once it touches a dedicated charger.
