Mi Air charge technology
Global technology leader Xiaomi announced Mi Air charge Technology an wireless charging system that the company claims is able to charge devices “within a radius of several meters.” Multiple devices can be charges at 5W at the same time. According to xiaomi and physical obstacles apparently don’t reduce charging efficiency.
Mi Air Charge Technology – 5W remote charging
The core technology of Xiaomi’s remote charging lies in space positioning and energy transmission.
Xiaomi’s
self-developed isolated charging pile has five phase interference antennas
built in, which can accurately detect the location of the
smartphone.
A phase control array composed of 144 antennas transmits millimeter-wide waves directly to the phone through beamforming.
On the smartphone side, Xiaomi has also developed a miniaturized antenna array with built-in “beacon antenna” and “receiving antenna array”.
Beacon antenna broadcasts position information with low power consumption. The receiving antenna array composed of 14 antennas converts the millimeter wave signal emitted by the charging pile into electric energy through the rectifier circuit, to turn the sci-fi charging experience into reality.
Currently, Xiaomi remote charging technology is capable of 5-watt remote charging for a single device within a radius of several meters.
Apart from that, multiple devices can
also be charged at the same time (each device supports 5 watts), and even
physical obstacles do not reduce the charging efficiency.
Future living rooms will be fully wireless
In the near future, Xiaomi’s self-developed space isolation charging technology will also be able to work with smart watches, bracelets and other wearable devices. Soon our living room devices, including speakers, desk lamps and other small smart home products, will all be built upon a wireless power supply design, completely free of wires, making our living rooms truly wireless.
This is a revolutionary innovation of wireless charging. This is also a bold attempt to turn the whole house wireless. It’s not science fiction, it’s technology. This is Xiaomi’s self-developed remote charging technology.
