What are the benefits of wireless charging and what are the pros and cons of wireless charging for m

The advantage of wireless charging is that you can do without restrictions, and you can charge it if you want to. And it's particularly convenient, the disadvantage is that the charge is not particularly much, and if this happens, that's the explanation. His charge is not particularly adequate.

Not far away. When it encounters metal, it heats up. The efficiency is not as high as that of a direct connection.

It is impossible to hurt the battery. Instead, it protects the battery. Because it is not limited by oxidation.

There is no need to connect the interface to cause aging. If the control is not done well, the battery will explode. Currently, only Silicon Tek has an anti-metal solution.

I can do it in the battery. Nothing else is safe.

The most troublesome thing about wired charging is the problem of wires, and it is easy to clutter the desktop or space if there are too many wires, but if you use wireless charging, you can solve these problems, and now there are some wireless charging pads that can support charging multiple devices at the same time.

The advantages of wireless charging are: reducing losses, high adaptation rate, etc., and the disadvantages are: the distance is too small, just a transition technology; I can't play with my phone while charging, etc., the details are as follows:

1. The benefits of Jingqiao wireless charging.

1. Reduce loss.

As we all know, when using wireless charging, you only need to connect the wireless charging pad to the power supply first, and then place the device that supports wireless charging on the wireless charging pad. Although wireless charging still needs to be connected to the power supply, it can reduce the use of data cables, avoid a lot of loss and waste of data cables, and is relatively environmentally friendly charging methods.

2. High adaptation rate.

Since the data cables used by different brands of mobile phones are not universal, such as Huawei and Apple, Huawei uses Type-C, while Apple uses Lightning, the two cannot be mixed. If you are using wireless charging, even if you are not using the same charging cable, as long as you support wireless charging, you can charge on the same wireless charging pad.

Second, the disadvantages of wireless charging.

1. The distance is too small, just a transition technology.

Because the magnetic field decays quickly in the air, the distance of the wireless charging technology of today's mobile phones is generally very small, and the general effective charging distance is only 3 8 mm. Counting the thickness of the charger + mobile phone shell + mobile phone protective case, the mobile phone charging must basically be close to the charger in order to effectively charge wirelessly. This limitation dooms this wireless charging technology to a transitional state.

2. You can't play with your phone while charging.

Most of the wireless chargers for mobile phones on the market today are laid flat, and the phone must be close to the charger. With this charging posture, you basically can't play with your mobile phone, and you have to use headphones to connect and listen. Even if Xiaomi has a vertical wireless charger, it can't change this situation.

Fundamentals of wireless charging:

1. Wireless charging technology: electromagnetic induction.

The alternating current of a certain frequency in the primary coil generates a certain current in the secondary coil through electromagnetic induction, thereby transferring the energy from the transmission end to the receiving end. At present, the most common charging solution uses electromagnetic induction, in fact, the electromagnetic induction solution in the technical realization does not have too much mystery and fierceness, China's local BYD company, as early as December 2005 applied for a non-contact inductive charger patent, the use of electromagnetic induction technology.

2. Magnetic field resonance of wireless charging technology.

Consisting of an energy-sending device and an energy-receiving device, when two devices are adjusted to the same frequency, or resonate at a specific frequency, they can exchange energy with each other, is a technology currently being studied, and a research team led by Marin Soljacic, a professor of physics at the Massachusetts Institute of Technology (MIT), used the technology to light a 60-watt light bulb two meters away and named it WitriCity.

The advantages of wireless charging for mobile phones include convenience, flexibility, and protection interfaces, while the disadvantages include low charging efficiency, slow charging speed, and high cost.

1. Benefits. 1. Convenience: Wireless charging of mobile phones eliminates the trouble of using charging cables. Users only need to place their phone on the charging dock and start charging without plugging and unplugging the charging cable. This makes the charging process much easier and faster.

2. Flexibility: Wireless charging eliminates the dependence on a specific charging cable. Users no longer need to carry and connect a specific type of charging cable, and can charge at any time on multiple charging docks that support wireless charging. This increases the user's charging options in the same scenario without teasing the liquid.

3. Protection interface: Wired charging requires frequent plugging and unplugging of the remaining charging cable, which may lead to damage or wear of the interface after long-term use. And wireless charging eliminates this problem, and the phone interface can stay in good condition for a longer time, extending the life of the phone.

Second, the disadvantages. 1. Low charging efficiency: Compared with wired charging, wireless charging has lower efficiency.

This means that it will take longer for the user to fully charge. In addition, since wireless charging requires energy conversion between transmitting and receiving, it can lead to shorter battery life.

2. Slow charging speed: Due to the low efficiency of wireless charging, the charging speed is relatively slow. This makes it necessary for users to wait longer for charging to be completed.

3. High cost: Wireless charging technology is still relatively new compared to wired charging technology, so its cost is high. This also means that wireless chargers may have higher ** than wired chargers.

Introduction to the principle of wireless charging of mobile phones

The principle of wireless charging of mobile phones is to use the principle of electromagnetic induction to transmit electrical energy from the transmitter to the receiver. Specifically, the wireless charger has a transmitter and a receiver inside. The transmitter converts electrical energy into radio waves through an electromagnetic field, which is then sent to the receiver.

The receiver converts radio waves into electrical energy through electromagnetic induction and stores it in a battery.

During wireless charging, an electromagnetic field needs to be established between the transmitter and receiver. This electromagnetic field is generated by the transmitter, and it can travel through the air to the receiver. When the distance between the receiver and the transmitter is close enough, the electromagnetic fields between them interact to transmit electrical energy to the receiver's battery.
