How does Wireless Charging Work for Mobile Phones?
I also watched a lot of people’s disassembly videos, including the wireless charging base, and when I removed it, I saw a circle of coils, and this coil range is very large, which is also to better let the mobile phone contact with the wireless charger, so as to form the purpose of charging!
Mobile phone wireless charging technology is a technology that uses magnets to charge mobile phones without the help of wires. Mobile phone wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transmit charge in the air between the charger and the mobile phone, and the coil and capacitor form a resonance between the charger and the mobile phone to achieve efficient power transmission technology.
Nowadays, wireless charging has also begun to be used in Bluetooth headsets, and wireless charging has also begun to appear DIY to the car, to the desktop directly to achieve customization! I saw a master, bought a lot of materials to make wireless charging equipment, and made a hole in his desk to achieve the goal of wireless charging pile!
According to the relevant information, they use the magnetic force of the magnet to complete the charging, and the iPhone also has magnetic wireless charging! But in the daily charging process, we did not find a sense of magnetic damping. In addition to Apple’s launch of magnetic wireless charging, this is more obvious, what is going on?
It turns out that wireless charging is electromagnetic inductive! Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, because the charger and the power device use a magnetic field to transmit energy, the two do not need to be connected by wires, so the charger and the power device can be exposed without conductive contacts.
On the market, wireless charging is divided into: electromagnetic induction, electromagnetic resonance, radio wave three solutions! Of course, the mobile phone uses electromagnetic induction, and the QI standard is used! So what is the QI standard.
Qi is the world’s first standardization organization to promote wireless charging technology; He introduced two characteristics: convenience and versatility. First of all, products of different brands, as long as there is a Qi logo, can be charged with Qi wireless chargers. Secondly, it overcomes the technical bottleneck of the “versatility” of wireless charging, and now it has realized that mobile phones, cameras, computers and other products can be charged with Qi wireless chargers, providing possibilities for large-scale applications of wireless charging.
Now get it? Summary: Mobile phone wireless charging is achieved through electromagnetic induction, without the data line can make the charger and the mobile phone contact can be charged, his charging method is the use of QI standardization, and disassembled, he is with chips and resistors and other equipment and coils to achieve unlimited charging function, do you understand?
