Concept of Wireless charging
Wireless charging is a technology which works on the principle of Electromagnetic induction. Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. The charger uses an induction coil to create an electromagnetic field, which the receiver coil in the phone converts back into electricity which is to be fed into the battery. Wireless charging is also known as cordless or inductive charging.
Key points for Wireless charging
- Wireless charging works by transferring energy from the charger to the receiver without any physical contact between charger and receiver.
- For wireless charging, a charger is required. Charger acts as a transmitter and smartphones or any other accessories like Cars, watches acts as a receiver.
Benefits of wireless charging
- Easily charge up the device without plugin into electricity board.
- Multiple devices can be charged simultaneously if devices have the same compatibility (same standard), also known as the Qi standard.
- Qi is an open interface standard that defines wireless power transfer using inductive charging over distances of up to 4 cm, developed by the Wireless Power Consortium.
- Easy to use i.e we have to simply put the gadgets or smartphone on the charging pad.
- Protected connections.
Is Wireless charging better than Wired charging
- Wireless charging takes more time to charge a device as compared to Wired charging due to this Power consumption of wireless charging is more as compared to wired charging.
- The difficulties of using smartphones while charging are less in Wired charging as compared to wireless charging. For example-if, we have to use our phone while charging we can easily use in case of wired charging but in case of wireless, we can’t use it more.
- Power consumption of wireless charging is high as compared to wired charging.
- Wireless charging is easy to use but slower as compared to wired.
Xiaomi introduced Mi Air Charge wireless technology
- This kind of charging has nothing to do with the Qi standard. The smartphones need to be outfitted with a “miniaturized antenna array with built-in ‘beacon antenna’ and ‘receiving antenna array’”. The smartphone has 14 antennas to convert a millimetre-wave signal that’s emitted by the charging pile. The signal is converted into electric energy through a rectifier circuit.
- Wireless charging technology requires the user to place their device or gadgets on a charging pad to charge but in Air charge wireless technology there is ‘remote charging pile’ that can detect the location of your smartphone and beam energy over to it through thin air.
- Air charge wireless technology can also charge multiple devices concurrently while you’re gaming, watching videos or doing anything else.
- Air charged wireless technology is more efficient than Wireless charging.
We’re excited to bring you the remote charging technology – Mi Air Charge Technology! Charge multiple devices simultaneously while you’re gaming, walking around or even when something’s in the way, no strings attached.
