Xiaomi Mi Air Charge Technology

Xiaomi Corporation is a Chinese multinational electronics company. The corporation makes and invests in smartphones, mobile apps, laptops, home appliances, bags, shoes, consumer electronics, and many other products. Xiaomi Corporation has just unveiled the “Mi Air Charge Technology”. This Mi Air Charge creates a wireless charging system that’s claiming to charge various electronic devices, “within a radius of several meters”.

Xiaomi’s blog post also states that the system can charge multiple devices at a rate of 5W per device. The technology is said to work not only with smartphones, but also with smartwatches and other wearables. The company said it has self-developed an isolated charging pile that has five phase interference antennas built-in. It can “accurately detect the location of the smartphone.” A company spokesperson said Xiaomi won’t be deploying this new system to consumer products this year.

The Air Charge helps to free up smartphones and associated wearables by doing away with cables and docks altogether. The charging system also includes other devices such as speakers, desk lamps, etc for a completely wireless area experience. It works by using five phase interference antennae in the base unit to “accurately” locate the charging device . Wireless charging itself done through a phase control array comprising 144 antennae bombarding millimeter waves directly at the device.

The process is somewhat similar to beamforming used in modern 5GHz capable wireless routers, except Xiaomi uses it for charging. The air charging system is only for Xiaomi devices because it will not work without the presence of a proprietary “miniaturized antenna array”. This array relays positional information to the base station. And  also converts the incoming millimeter waves into electrical energy that provides charging. Xiaomi claims that the wireless charging system works efficiently even through physical obstacles.
