Does wireless charging conform to the real wireless technology
At present, smart phones are gradually equipped with the "wireless charging" function. Specifically, the mobile phone can be charged by putting it on the wireless charging base, but the charging will stop once the mobile phone leaves! Can this really be wireless charging?
In fact, we really understand that wireless charging is a mistake. As we say now, as long as the charging line is not connected to the charging port of the mobile phone, charging can be realized. This is obviously not in line with the real wireless charging, wireless charging, because it can not leave the wireless charging transmitting device when charging; back to itself, if it is connected with wireless Bluetooth headset and wireless Internet. Can wireless charging be considered as real wireless?
Why is this charging scheme called wireless charging?
Smart phones can be said to change very fast. Wireless chargers, in addition to some basic functions, also have other functions. Some functions seem to have great differences every time they are upgraded and updated. But in the field of wireless charging technology, it may be a long way to go to break through. But in the face of those wireless devices such as wireless headphones, wireless remote control, etc., wireless charging is comparable. Without the power cord, people call it "wireless charging" by the way.
Should we call it wireless charging?
Wireless charging technology can be understood as induction charging, which is a non-contact charging method. Its principle is to use near-field induction to realize charging, and the wireless charging device will transfer the energy to the battery of smart phone. This forms a more convenient charging scheme than using a charging line, which is today's understanding of wireless charging.
It is more practical to call it "inductive charging". Wireless wireless should have one condition, that is, charging can be realized without restriction in a certain distance range! Obviously it did not. On that day, it is no longer restricted by wireless transmitter, which is the real wireless charging.
"Can't charge without wireless transmitter" becomes its fatal short board!
There was a famous physicist Nikola Tesla who had been involved in the research of this field a few years ago. At last, he thought that Nikola coil can realize wireless power supply. As long as the experiment is successful, there is nothing difficult in the world! But the experiment ended in failure. At present, wireless charging technology is still developing and improving. Although it has many advantages, it can not be mobile charged or separated from the wireless transmitter, which is the most fatal problem.
In the view of foreign media, in recent years, some foreign scientists have been studying this aspect, or will call it an isolated charger. The wireless charging range is within 1 meter. Users can realize wireless charging as long as they do not exceed this area. Presumably, this success should not be too far away. At that time, when users don't need to worry about wireless charging, they have to put the mobile phone on a fixed base.
Advantages and disadvantages of current wireless charging (inductive charging)
Advantages: in terms of safety and convenience, it can be said to have more advantages. Firstly, in terms of safety, wireless charger can avoid unnecessary danger when two ports are in contact; on the other hand, it can charge multiple devices at the same time, and the car wireless charger doesn't need to worry about insufficient sockets, and solves the problem of winding multiple charging wires.
Disadvantages: low charging efficiency, slow charging speed, can not leave the device providing charging, high production cost, serious battery damage, etc.
The real realization of wireless charging is not far away from us. As long as we keep innovating and dare to repeatedly challenge and experiment, sooner or later we will use all wireless devices, mobile power wireless charging, and officially step into a real wireless era.
