Step to select the most appropriate position, be careful not to let the part of the connection line warped phenomenon.
2, question six: How to do wireless charger wirelessThe charger is connected to the mobile phone through two coils, and as long as there is coupling current, the mobile phone can be charged normally. Question seven: Self-made simple wireless charger transmitter is now common QI solution, you can search a lot on a treasure, find the basic module, and then built into their own products.
3, two meters temporarily impossible, personal production needs to consume a lot of power, the loss is also very large, centimeter level can buy their own on Taobao touchstone modification.
4, wireless charger can use the kind of Apple universal, the receiving end with a thin made of cardboard thatThe kind is directly attached to the back of the mobile phone, the charging head is stuck into the inherent charging interface of the mobile phone, and then a mobile phone case or mobile phone cover is very perfect to achieve self-made desktop wireless charging .
5, now common is the QI solution, you can search a lot on a treasure, find the basic module, and then built into their own products. There are also A4WP solutions, which are relatively rare at present, but because the charging distance and area have been greatly improved, it is considered to be the second generation of wireless charging technology.
1, it is best not to change the homemade desktop wireless charge , because homemade desktop wireless charge you both are output, afraid of problems, you will buy a set of USB male and female connector, Put your original wireless charger on homemade desktop wireless charger To the mobile phone homemade desktop wireless charge The charging line is broken for two connected to your male and female connection head it is not good to use homemade desktop wireless charge .
2. The installation operation is very simple, users only need to connect their own charging board cable to the Lightning interface, as shown below: The following is the test diagram: Wireless charging refers to the device that uses the electromagnetic wave induction principle to charge, the principle is similar to the transformer, and there is a coil at the sending and receiving end. The sending coil is connected to the wired power supply to generate electromagneticThe receiving coil senses the electromagnetic signal at the sending end to generate a current to charge the battery.
3, convenient: charging does not need to be connected with wires, as long as it is placed near the charger, there is no need to occupy multiple power sockets, there is no trouble of multiple wires winding each other. The disadvantages of wireless charging are slightly lower in efficiency: the general charger also has a transformer, but the wireless charging transformer composed of the transmitting coil and the receiving coil is limited in structure, and the energy transmission efficiency is theoretically slightly lower than that of the general charger.
4, if you use vivo mobile phone, wireless charging is also known as inductive charging or non-contactInductive charging, based on the principle of electromagnetic induction, the device that needs to be charged can be charged by contacting the wireless charger after being energized.
5, prepare the accessories needed for charging, Qi wireless charger, wireless charging receiving coil. With these ready to go, we're ready to operate. Plug the wireless charging receiver coil into the phone port, just like you normally charge. Plug in the receiving coil, after the link is good, the wireless charging receiving coil is finally placed on the back of the phone, without affecting the use of the case.
6, the use of wireless magnetic induction charging equipment can be invisible, equipment wear rate is low, a wide range of applications,The area of public charging area is relatively reduced. High technical content, easy to operate, can implement relatively long distance radio energy conversion. Disadvantages of wireless charging: Although the technical content of the equipment is high, the economic cost of the equipment is high and the maintenance cost is large.
Two meters is not possible, personal production requires a lot of power,The loss is also very large, centimeter level can buy their own on Taobao touchstone modification.
Wireless charger is actually the use of electromagnetic induction principle for charging equipment, similar to a transformer, there is a coil at both ends of the sending and receiving, the sending end of the coil connected to the wired power supply to generate electromagnetic signals, the receiving end of the coil induction of the sending end of the electromagnetic signal to generate current to the electrical equipment. As shown in the figure below, current flowing through the coil creates a magnetic field. The proximity of other unenergized coils to a magnetic field generates an electric current.
Wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, noA transmission cable is needed to transmit electricity to the device like a traditional wired charger, but the device that needs to be charged can be charged by touching the wireless charging base.
Generates a magnetic field through the coil and then passes through the receiving coil to convert the magnetic field into electricity, which is why this wireless charging device often carries a thick base and "phone case".
Convenient: no need to connect with a wire when charging, as long as it is placed near the charger, there is no need to occupy multiple power sockets, there is no trouble of multiple wires winding each other. The disadvantages of wireless charging are slightly less efficient: there is also a transformer in the general charger, but wireless chargingThe transformer composed of the transmitting coil and the receiving coil is limited in structure, and the energy transmission efficiency is theoretically slightly lower than that of the general charger.
General charger also has a transformer, but wireless charging to transmit coil and receive coil composed of transformers due to structural limitations, energy transmission efficiency in theory will be slightly lower than the general charger. Therefore, there will be no loss caused by mechanical wear and flaring during connection and separation. When charging, there is no need to connect with a wire, as long as it is placed near the charger, there is no need to occupy multiple power sockets, and there is no trouble of multiple wires entangling each other.
