1, the test results show that the wireless transmission distance is about 15 centimeters, but Fujitsu says that the wireless transmission distance can eventually be achieved several meters. It should be pointed out that the further away from the device, the more power lost in transmission.Fujitsu's system is similar to technology developed by Witricity, an American company, which also uses magnetic resonance to transmit electricity over distances of several meters.
2, the principle of wireless charging is that through near-field induction, the wireless charging device conducts the energy to the charging terminal device, and the terminal device converts the received energy into electrical energy stored in the battery of the device. The principle of energy conduction is inductive coupling, which can ensure that there is no exposed conductive interface, which can not only save the messy transmission line between the equipment, but also be safer for electronic devices such as electric toothbrushes that are often in contact with conductive media such as liquids.
3, the principle of wireless charging technology is electromagnetic induction, magnetic field resonance, radio wave and so on. Electromagnetic induction type primary coil a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain current, thereby transferring energy from the transmission end to the receiving end.
4, 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 wireless2 >

2. In addition to supporting super wired fast charge, some high-end mobile phones of Huawei can also support wireless charging, and wireless chargers need to be purchased separately to use wireless charging. How to use Huawei wireless charger? Connect the charger (the charging tip that came with your phone or was purchased separately) to a power source. Connect data cableUse a data cable to connect the charger to the wireless charger. Place the phone Place the rechargeable area of the phone in the center of the upper surface of the wireless charger, and the phone shows that it is charging.
3, Huawei p40 wireless charging operation method Huawei wireless charging only for some mobile phones have this function, not all mobile phones have. This section describes how to enable and operate Huawei p40 wireless charging. Turn on wireless charging First, tap on [Settings] on the desktop of your phone.
4, this article will give you a detailed introduction to the whole process of millet 11 wireless charging, so that you can easily open wireless charging mode. viewFirst, open "Settings", go to "Battery and Performance", and look for the "wireless charging" option. If you see it, it means that your Mi 11 has wireless charging superpowers! Choose Qi standard charger Secondly, choose a wireless charger that is in line with Qi standard.
5, wireless charger usage: the mobile phone standard charger and data cable connected to the wireless charger, and then the mobile phone is/horizontal 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.
Traditional wireless charging solutions: In general, the traditional way of charging is to use electromagnetic induction to complete. That is to say, when the current flows through the charging coil of the charger, a corresponding magnetic field will be generated. The receiving coil in the mobile phone can generate current by sensing changes in the magnetic field, thus realizing wireless mobile phone charging. This charging method is indeed more convenient, at least to solve the problem of charging line loss, but also saveA lot of space.
MOTOROLA built a breakthrough system based on Qi technology that not only makes charging wireless, but also automatically recharges in the background, even in the pocket. However, this technology requires extremely high spatial accuracy, and any object that intervenes will interrupt the charge. To address this challenge, MOTOROLA joined forces with GuRu, an innovative company focused on improving charging efficiency.
Wireless charging sounds great in theory, but it's just a little more convenient than wired charging. You insert the puck or stand on the wall with a wire, and then place the device on the puck. Now,MOTOROLA said it will partner with Guru Wireless to move away from tablets and go truly wireless. Well, it's almost real wireless. Guru Wireless refers to its technology as OTA (over-the-air) wireless.Or increase the heat dissipation of the active fan, and use the fan to cool the motherboard and coil, which can achieve the delay power reduction time. As long as the temperature on the NTC inside the phone does not reach the set critical point, it can keep the phone charging quickly.
The wireless charging solution proposed by GuRu mainly uses millimeter wave,It can achieve wireless charging over long distances, and according to its introduction, it can achieve charging at a distance of several feet (1 foot =30.48 cm). If the pain point of near-distance wireless charging is solved, even if the user holds a mobile phone, the desire to use the device at any time may be realized.
The basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and then converted into a current to be transmitted to the intelligent terminal. When the system works, the input terminal will be rectified by AC mains through the full bridgeThe circuit is converted into direct current, or the 24V direct current terminal is used to supply power directly to the system. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charger refers to the charger that does not need to be connected to the terminal device that needs to be charged without the traditional charging power cord, using the latest wireless charging technology, through the use of the magnetic field generated between the coils, the magic transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment.
