What is the principle of wireless charging?

Principle of wireless charging: electromagnetic induction. The charging base and the mobile phone terminal have built-in coils respectively. When the two are close, the generating coil generates a certain current in the mobile phone receiving coil based on a certain frequency of alternating current through electromagnetic induction, thereby transferring the point energy from the originating end to the receiving end, and then starting to supply power to the mobile phone from the charging seat. Magnetic resonance.

Wireless charging, also known as inductive charging, non-contact inductive charging, from wireless power transmission technology, 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 energyThe battery is charged and at the same time used for its own operation.

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 end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. 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.

Devices that use the principle of electromagnetic induction for charging, the principle is similar to that of transformers, by setting coils at the transmitting and receiving ends,The transmitting coil sends out an electromagnetic signal under the action of power, and the receiving coil receives the electromagnetic signal and converts the electromagnetic signal into current, so as to achieve the purpose of wireless charging.

Apple 13 wireless charge good or direct charge good

Apple straightened. 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. This wired charging will be better, some, because you wired charging, it will charge more efficiently, wireless charging, it will be slower. noWhat's good and bad. As long as the battery is used, the battery life will be lost, which is a common problem of every mobile phone, and it is inevitable.

Apple wireless charging is good or wired charging is good, each has its own advantages and disadvantages. Because the built-in lithium battery capacity of the Apple phone is relatively small, although it is optimized from the hardware and software, it is still inevitable that the need for two charges a day is multi-charge, and the use of wireless charging can be charged at any time without feeling, and can be charged at will, of course, the disadvantage is that it can not be used over charge. Wired charging can be used while charging but must be bound by the charging cable.

This wired charging will be better, oneSome, because if you have wired charging, it will charge more efficiently, and wireless charging, it will be slower.

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 of the plug a wired charge power line, it can be energized, so I think wireless charging is still a chicken fin a product, It's just that you don't have to plug your phone into a charging port every time.

According to user feedback, the wireless charging function of the Apple 13 series is still relatively convenient and easy to useFuck. Since the Apple 13 series supports the Qi wireless charging standard, it can be charged using a wireless charger that complies with the Qi standard. All you need to do is place the iPhone 13 on a wireless charger to start charging. Compared with the traditional wired charging method, wireless charging can be more convenient to use, without worrying about cable damage or power failure.

iPhone13 official is not equipped with wireless charger, and the official website does not have wireless charger accessories to buy, you need to buy their own. iPhone13 Buy wireless charger, preferred MagSafe magnetWireless charging, higher power, faster charging speed.

Is it better to charge an iPhone directly or wirelessly?

1, direct charge that can charge 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. This wired charging will be better, some, because you wired charging, it will charge more efficiently, wireless charging, it will be slower. There is nothing good or bad. As long as the battery is used, the battery life will be lost, which is a common problem of every mobile phone, and it is inevitableYes.

2, 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. 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.

3, Apple mobile phone general we are better with direct charging, its charging effect is also a direct point, wireless charging is now a more novel way, but I still accept wired charging is better. Total perceptionIf you have money to charge it, the battery will charge it more efficiently. The iPhone12 can be charged wirelessly or via wired.

4, Apple mobile phone general we are better with direct charging, its charging effect is also a direct point, wireless charging is now a more novel way, but I still accept wired charging is better. I always feel that the money will charge the efficiency of the battery will be higher.

5, 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. But conversion effectPull out the charging cable and simply place the device on the charger to start charging, which is very convenient. Aesthetic: Wireless charging will not damage the shell design of the device, making the overall device look more beautiful.

2, wireless charger is good, convenient, safe and durable; The disadvantages are bondage, high price and low efficiency. Advantages of wireless charger: Convenient: wireless charging belongs to one-to-many charging, which solves the problem that the interface is not applicable, and also avoids the phenomenon of poor contact caused by repeated plugging and unplugging of the mobile phone interface, which can better protect the mobile phone interface.

3, high charging efficiency modern wireless chargingThe device usually has a fast charging function, and its charging efficiency is not inferior to that of wired charging. At the same time, wireless chargers can also adapt to different equipment needs to meet the charging needs of a variety of devices. This can be very beneficial for multi-device users.

4, different, the wireless charger will have a loss when charging, the loss is between 30-40 percent. So the ordinary charger is faster than the wireless charger. There are already fast chargers and fast wireless chargers, but the results are the same. For example, the fast charging Samsung S8 takes 90 minutes, then the fast wireless charger takes 190 minutes, which is meThe result of my own actual test.

5, hello, of course, flash charger is fast, VOOC flash charge: VOOC flash charge is the world's first mass-produced commercial fast charge scheme, compared with other fast charge schemes, the technical threshold is higher, VOOC flash charge requires a customized adapter and battery use. OPPO customized a special adapter, battery, data cable, circuit, interface, and for this in-depth development of intelligent all-end five-level protection technology, security is impeccable.

6, the pursuit of higher portability and comfort, you can choose wireless charging; Pursue faster charging speed andFor a wider range of applications, wired charging can be selected. The advantage of wireless charging is that it provides higher portability, which is especially suitable for wearable devices, smart home and other fields. However, the charging speed of wireless charging is relatively slow, and the distance between the charger and the device will affect the charging effect.

Is fast charging technology as fast as possible?

1, now the charging speed of smart phones is getting faster and faster, and some can even be full in 15 minutes. For battery anxiety, this means quick blood flow, especially in the rushGames, when you're in a hurry to go out. Although the impact of charging speed on the battery and mobile phone is almost negligible, but the user's concern is also increasing, mobile phone charging faster and faster is safe? Mobile phone manufacturers will not blindly increase the charging power regardless of safety.

2, in fact, fast charging is not the faster the better, although the fast charging speed is fast, it also has a certain impact on the service life of the mobile phone battery. At the same time, it is also necessary to solve the problem of battery life, which cannot be happy speed and short battery life. Fast charging of mobile phones is very harmful to the battery life of mobile phones and is unsafe, and fast charging is just one step closer to changing the name of the technologyBut still need to win steadily. Mobile phone fast charging technology is not the faster the better, the most important thing is to match with the mobile phone.

3, of course, the higher the charging efficiency of the mobile phone, the better, but the charging power is not so, because the higher the charging power, the faster the charging speed in theory, but this is not proportional. And the charging power is too large, it will also have some safety problems, it should be controlled in a reasonable range.

4, slow charge is more beneficial to the battery. Charging, whether normal or fast, will lead to the loss of battery power, but fast charging will accelerate the process,The maximum capacity percentage of the battery drops faster. Fast charging requires a dedicated data cable and charging head. For example, OPPO mobile phones need to use the original data cable and charging head to support fast charging, and other non-original devices may not be able to achieve fast charging.

5, the answer is yes, although fast charging can improve the charging efficiency of the mobile phone, it also has an impact on the battery life. Therefore, if you are used to changing a mobile phone in one or two years, or are willing to replace a new battery, the impact of fast charging mobile phones is minimal for you, it is recommended that this part of the user is preferred to consider fast charging mobile phones, bringing a better experience. But if you want toIf you do not replace the battery and use the phone for 2-4 years, you can consider mobile phones that do not support fast charging.

6, w faster than 66w and no harm, in general, the higher the power of the charger, the faster its charging speed, according to this standard, if the charging speed of 100 watts and 66 watts, in the case of the same technical principles and standards, 100 watts of charging speed much faster. The higher the number, the faster the charging speed, the better.
