What Is Qi Standard Wireless Charging?
Qi (pronounced “chee”) is a widely adopted wireless charging standard that enables the transfer of electrical energy between a transmitter and receiver without the need for cables or wires. The Qi standard, developed by the Wireless Power Consortium (WPC), is designed to provide a safe, efficient, and convenient way to charge devices such as smartphones, watches, and earbuds.
How Qi Wireless Charging Works
Qi wireless charging uses a technology called electromagnetic induction, which involves the transfer of energy between two coils: a transmitter coil in the charging base and a receiver coil in the device to be charged. When a Qi-enabled device is placed on a Qi-compatible charging pad, the transmitter coil in the pad generates an alternating magnetic field, which induces an electromotive force (EMF) in the receiver coil of the device. This EMF is then converted into electrical energy, which is used to charge the device’s battery.
