1, the basic principle of wireless charging is to convert the current into a magnetic field, which is transmitted through the air and converted into a current to be transmitted to the intelligent terminal. System operating hoursThe input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V DC end 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.
2, wireless charging system mainly uses 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.
3, wireless charging is also known as inductive charging or non-contact inductive charging, based on the principle of electromagnetic induction, it is not necessary to transmit electricity to the device like the traditional wired charger, but the device that needs to be charged can be charged by contacting the wireless charging base.
Apple mobile phone general we are better with direct charging wireless charging self , its charging effect is also a direct point, wireless charging is now a relatively newThe way, but I still accept the wired charge is better. I always feel that the money will charge the efficiency of the battery will be higher. The iPhone12 can be charged wirelessly or via wired.
Apple straight. Direct charge can be charged fast, but also can play at the same time, wireless charging time is long and slow, and wireless charging can be done at night when the mobile phone is not used. However, the conversion efficiency is best at about 80%, and the remaining electric energy can only be converted into heat energy, so the heat of wireless charging has been a big problem. So are high-powered wireless chargersNeed to be equipped with an active cooling fan.
Apple cable charge well. The advantage of magnetic suction is that it can be adsorbent close to the adsorption can be charged, the charger is automatically aligned with the position of the charging coil, solving the problem that the traditional wireless charging requires manual alignment; But it is still a wired form, and the power is not as good as wired charging, so the key moment or wired charging is more realistic. If the MagSafe magnetic charger wants to turn into a regular one, it will depend on when the iPhone removes the charging port.
Apple straight. Direct charge is fast charge, andCan play at the same time, wireless charging time is long and charging is slow, and wireless charging can be done at night when the mobile phone is not used. The iPhone uses lithium-ion batteries, which have the advantages of fast charging, long lasting use, higher power density and the ability to provide longer battery life in a lighter volume.
I think Apple mobile phone or wired charge is better, or more convenient, if you use wireless charging, in fact, in the wireless charging device to the back but also plug a wired charge power line, it can be powered, so I think wireless charging is still a chicken side of a product, onlyIt's that you don't have to plug your phone into the charging port every time.
"Wireless charging" uses a special device to convert power from an electrical outlet into rechargeable airwaves, before the wires are droppedAfter discarding, you can charge your electronic devices directly. Wireless charging basically transfers energy through a magnetic field.
Mobile phone wireless charging refers to the meaning that the charger and the electrical device can be connected to the phone without wires.
Wireless charging refers to the charger on 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, magical transmission of electrical energy, inductive coupling technology will become a bridge connecting the charging base station and equipment. How to use: Connect the USB cable and plug it into the socket.
2, Apple cable charge well. The advantage of the magnetic magnet is that it can be adsorbated near, and the adsorption can be charged. The charger is automatically aligned with the position of the charging coil, which solves the problem of manual alignment for traditional wireless charging. But it is still a wired form, and the power is not as good as wired charging, so the key moment or wired charging is more realistic. If the MagSafe magnetic charger wants to turn into a regular one, it will depend on when the iPhone removes the charging port.
3, cable charging is good. inIn the case of the same charging time, the power of the commonly used wired battery charger after charging is 93%, and the power of the wireless charger after charging is 88%. Obviously, there is still a gap in the charging efficiency of wireless chargers, and there is still room for further improvement in technology.
4, the second kind of wireless charging, its working principle is the most used electromagnetic induction, wireless charging less line bondage, each charge with the release, compared with wired charging, it does not plug and unplug the data cable cumbersome, so charging is more safe, more fast, its disadvantage is that the charge is relatively slow.
5, wire faster, althoughWireless charging is a very practical function, but only some users, wired charging faster, wireless charging more flexible, get rid of the bondage of the wire, pick up and put down, without alignment, you can quickly charge. Both sides have their advantages and disadvantages and can make up for each other.
