Generally, the transmission distance of high-power wireless charging can reach 5 meters in about 0.9-2 metersElectrical 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 infrared wireless charging , such as the Qi method of mobile phone charging infrared wireless charging , but ZTE's electric vehicle wireless charging method uses induction.
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 technique mentioned aboveThe use of electromagnetic waves as a medium is now staying 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 core magnetic resonance medium and long distance wireless charging developed by Spurotin can successfully achieve wireless charging within one meter.
1, yesInfrared devices to achieve infrared charging, and in this way can better supply power, but also to allow the battery to get better protection.
2, get rid of the shackles of data lines and wireless chargers The current wireless charging technology is still in its infancy, compared with the traditional charging method, the mainstream wireless charging is just the data line into a wireless charger. Only when the phone is close to the charger, it can be charged normally.
3, I personally think this thing is not practical, because this is an ideal situation, can be 30 meters away equipment for infrared wirelessThe charge, and the 400W power, only 85W reaches the device. I don't know, it's really not practical at this stage.

1, in fact, it is certain to tell you that the harm of wireless charging to the human body is very small, almost negligible. This is like the Wi-Fi, mobile phones, TVS and other electronic products we usually use, and we do not exist between the transmitter and the receiver the radiation level is small, and the main frequency absorbed by the human body is inconsistent with the charging frequency, so we can not worry about the harm of wireless charging. 2, the Ministry of Industry and Information Technology communications Department staff said that wireless chargers have radiation is inevitable, but since it has been listed, it means that it must meet international standardsSure, it will not cause great harm to the human body. For this view, He Guili, director of the Tel Laboratory of the Telecommunication Research Institute of the Ministry of Industry and Information Technology, agreed: "Wireless chargers as long as they are done in accordance with technical specifications, there will be no radiation harm to the human body." But there is a key problem.
3, conclusion: Wireless chargers do produce electromagnetic radiation, although the value is usually small, but should be wary of its possible cumulative effect. With the popularity of wireless charging technology, users are exposed to more and more radiation sources in daily life, such as mobile phones, computers, WiFi, etc., and long-term accumulation may have an impact on health. Wireless charging technologyTechnology and controversy With the development of the mobile Internet, the rise of wireless charging has led to discussions about electromagnetic radiation.
4, for the human body: wireless charging technology is safe and harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
5, wireless charging technology has radiation to the human body? Does it cause cancer? Tests have proved that wireless chargers can indeed produce electromagnetic radiation, but the value is relatively small. Use nowPeople are exposed to more and more radiation: computers, tablets, mobile phones, WiFi, TVS, microwave ovens... The cumulative radiation value is very high, and if the user lives in such a high radiation environment for a long time, it may cause serious harm to the body and mind.
6, there is a little radiation, as long as the person is not between the transmitter and the receiver, the radiation level is very small, and the charging frequency is inconsistent with the main absorption frequency of the human body, the harm is completely negligible.
1, the amount of charging within minutes reaches or exceeds infrared wireless charging 10%, the charging efficiency is even higher than the direct use of wireless chargers. In contrast, the deep blue SL0 Long comfortable Da and Wei brand Blue Mountain DHT-PHEV for Apple iPhone 13 Pro is obviously not very friendly, 15 minutes of charging is 3%, and its infrared wireless charging his test model compared to a large gap.
2, the highest charging efficiency of Xiaomi and Huawei need the mobile phone endSupport their own protocol, so infrared wireless charging We separately tested infrared wireless charging Huawei Mate 30 with Huawei wireless charging mobile phone bracket and Xiaomi 10 with Xiaomi wireless charging mobile phone bracket. The standard test uses the iPhone 11 pro with all wireless charging phone stands, and the rule is to keep the phone lit, and test the time required to charge 10% (from 40% to 50% of the phone charge) on all products under test.
3, storage space,The performance of both cars was satisfactory. Due to the use of the shield design, the two cars have a lot of storage space under the center console, XOPeng P7 is equipped with mobile phone wireless charging function, but Tesla in the cover for the USB charging port harness reservation is more humane, if the Xopeng P7 directly connected in the armrest, the charging cable will be clamped by the cover.
4, in addition to wireless charging, built-in tachograph, as well as the general sign of the active noise reduction, the configuration of CT5 hand advantage. Jaguar's interior is infrared wireless charger I think the best of the three, or the most designed. Sitting in the driver's seat, there is a strong sense of surrounding, everywhere is a leather package, and the two-color color scheme can mobilize the atmosphere. The LCD screen is well integrated in the XEL interior, and the dashboard, air conditioning control area, and rearview mirror are all LCD screens.
5, leather steering wheel and leather seats in the middle and high models are equipped, the leather feel of the steering wheel is better, the leather seat is not looking too simple. The configuration of the two models is quite rich, and we tested the high configuration of the car
