What Is Qi Wireless Charger?
A Brief History of Wireless Charging
Wireless charging, also known as inductive charging, has been around for several decades. The concept of wireless charging dates back to the 19th century when scientists discovered that an alternating current (AC) could be generated by a coil of wire when it was placed near another coil of wire. However, it wasn’t until the 1990s that the first wireless charging systems were developed for use in industrial and commercial applications.
The technology behind wireless charging is based on the principle of electromagnetic induction, which was discovered by Michael Faraday in 1831. When a coil of wire is placed near another coil of wire and an alternating current is passed through the first coil, it generates a magnetic field that induces an electric current in the second coil. This is the basis for wireless charging, where a transmitter coil is used to generate a magnetic field that induces a current in a receiver coil, which is connected to a device that needs to be charged.
The first wireless charging systems were developed for use in industrial and commercial applications, such as powering devices in factories and warehouses. However, it wasn’t until the development of the Qi wireless charging standard that wireless charging began to be used in consumer electronics.
The Qi Wireless Charging Standard
The Qi wireless charging standard was developed by the Wireless Power Consortium (WPC) in 2008. The WPC is a non-profit organization that aims to promote the development and adoption of wireless charging technology. The Qi standard is an open standard that allows devices from different manufacturers to be charged wirelessly using a common interface.
The Qi standard specifies a set of requirements for wireless charging systems, including the frequency range, transmission power, and receiver sensitivity. The standard also includes guidelines for the design and testing of wireless charging systems to ensure interoperability between devices from different manufacturers.
The Qi standard has been widely adopted by the mobile industry, with many smartphone manufacturers, including Apple, Samsung, and Google, incorporating Qi wireless charging into their devices. The standard has also been adopted by other industries, including automotive and medical, where wireless charging is used to power devices in vehicles and medical equipment.
How Qi Wireless Charging Works
Qi wireless charging works by using a transmitter coil to generate a magnetic field that induces a current in a receiver coil. The transmitter coil is connected to a power source, such as a wall adapter or a USB port, and is designed to transmit a specific frequency of electromagnetic energy.
The receiver coil is connected to a device that needs to be charged, such as a smartphone or a smartwatch. The receiver coil is designed to be sensitive to the specific frequency of electromagnetic energy transmitted by the transmitter coil and is able to induce a current in the device.
The process of wireless charging using Qi technology is as follows:
- The transmitter coil generates a magnetic field that induces a current in the receiver coil.
- The current induced in the receiver coil is then used to charge the device connected to it.
- The charging process is continuous, with the device being charged as long as it is in contact with the transmitter coil.
