With the development of technology, wireless charging technologies have become a new trend in the mobile phone industry. The iphone, as one of the most popular smartphones in the market, naturally supports wireless charging. So, what exactly is the iphone wireless charging principle? This paper will lift this mysterious veil。
I. Rationale for wireless charging
The rationale for wireless charge is achieved using electromagnetic induction principles. In short, charging is achieved by creating a magnetic field between chargers and mobile phones that generates currents of the wire inside the cell phone. This approach avoids the extraction process when traditional wired charge is used, making charging easier。
Ii. Iphone wireless charging principle
1. Qi standard
To ensure the interoperability and interoperability of wireless charging technologies, apple applied the qi (qualcomm quick challenge) wireless charge standard to iphone 7 and later. Qi is a wireless charging technology alliance initiated and promoted by highcom to develop a global set of wireless charging specifications。
Magnetic chargers
Iphone supports the use of magnetic inhaler chargers for wireless charging. The charger has a loop inside which, when the mobile phone approaches the charger, it senses the magnetic field and produces currents that charge the cell phone. Magnetic chargers have the advantage of being simple to install, but the disadvantage is that users are required to match their mobile phones manually with chargers, which can easily lead to the charge instability。
3. Vehicle-borne wireless chargers
In addition to magnetic chargers, iphone supports the use of vehicle-borne wireless chargers for charging. The chargers are also internalised with a wire loop, which senses the magnetic field and creates currents that charge the phones when they approach the chargers. The advantage of a vehicle-mounted wireless charger is that it does not need to be aligned manually, but the disadvantage is that its scope of application is limited and it can only be used in vehicles with wireless chargers。
4. Magnetic insinuations of wireless filling pads
In addition to magnetic and vehicle-mounted wireless chargers, iphone supports the use of magnetic absorbent wireless chargers for wireless charge. This fast-charging pad contains a wire and a modem, which, when the mobile phone is placed on the fast-charging pad, senses the magnetic field and generates currents to charge the mobile phone. The advantages of a magnetic insinuation wireless filling pad are good compatibility and can be applied to multiple scenarios, but the disadvantages are high costs。
Summary: the iphone principle of wireless charge is based primarily on electromagnetic sensing, which completes the charging process by making current transfer by establishing a magnetic field between chargers and mobile phones. Currently, iphone supports a variety of wireless charging methods, including magnetic inhaler chargers, vehicle-borne wireless chargers and magnetic inhaler wireless chargers. The wireless charge experience of iphone will be further enhanced as wireless charge technology continues to develop and improve。
