What Is Wireless Charging Technology?
A Brief History of Wireless Charging
Wireless charging technology has been around for several decades, with the first patent for a wireless charging system filed in 1896 by Nikola Tesla. However, it wasn’t until the 1990s that the first commercial wireless charging systems were developed. These early systems used electromagnetic induction to transfer energy between two coils, one in the transmitter and one in the receiver. This technology was primarily used in industrial applications, such as powering electric toothbrushes and other small devices.
How Wireless Charging Works
Wireless charging technology works on the principle of electromagnetic induction, which is the process by which an electric current is generated in a conductor when it is exposed to a varying magnetic field. In a wireless charging system, a transmitter coil is used to generate a magnetic field when an alternating current (AC) is passed through it. This magnetic field induces an electric current in a receiver coil, which is typically located in a device such as a smartphone or a smartwatch.
The process of wireless charging involves several key components:
- Transmitter coil: This is the coil that generates the magnetic field in the transmitter.
- Receiver coil: This is the coil that induces an electric current in the receiver.
