Understanding Wireless Charging Technology
How Wireless Charging Works
Wireless charging, also known as inductive charging, relies on the principle of electromagnetic induction. It involves two key components: a transmitter coil and a receiver coil. The transmitter coil, located in the charging pad, generates a fluctuating magnetic field when an electrical current is passed through it. This magnetic field induces an electrical current in the receiver coil, which is embedded in the device being charged. This induced current is then used to power the device’s battery.
Qi Standard: The Universal Language of Wireless Charging
To ensure compatibility between different wireless charging devices, a global standard called Qi (pronounced “chee”) was developed. The Qi standard defines the technical specifications for wireless charging, including the frequency of the magnetic field, the power output, and the safety protocols. Devices that comply with the Qi standard can be charged using any Qi-certified wireless charger.
