What Is Qi Standard for Wireless Charging?
Introduction to Qi Standard
The Qi standard, also known as Wireless Power Consortium (WPC), is a widely adopted technology for wireless charging. It enables devices to be charged without the need for cables, making it a convenient and user-friendly solution for consumers. The Qi standard is an open standard, meaning it is available for anyone to use, and it has become the de facto standard for wireless charging.
The Qi standard is a significant innovation in the field of wireless charging, and it has revolutionized the way we charge our devices. With the Qi standard, consumers can charge their devices on a wireless charging pad or surface, eliminating the need for cables and reducing clutter. The Qi standard is also backward compatible, meaning that devices that support the Qi standard can be charged on any Qi-compatible charging pad or surface.
History of Qi Standard
The Qi standard was first introduced in 2008 by the Wireless Power Consortium (WPC), a non-profit organization that aims to promote the adoption of wireless power technology. The Qi standard was developed to provide a common interface for wireless charging, enabling devices from different manufacturers to be charged on the same charging pad or surface.
The Qi standard has undergone several revisions since its introduction. The first version of the Qi standard, known as Qi 1.0, was released in 2009 and supported charging at a maximum power of 5W. In 2012, the WPC released the Qi 1.1 standard, which increased the maximum charging power to 10W. In 2014, the WPC released the Qi 1.2 standard, which added support for resonant charging and increased the maximum charging power to 15W.
How Qi Standard Works
The Qi standard uses a technology called magnetic induction to transfer energy between a charging pad or surface and a device. The charging pad or surface contains a coil of wire that generates a magnetic field when an alternating current (AC) is applied to it. The device to be charged contains a receiver coil that is designed to be sensitive to the magnetic field generated by the charging pad or surface.
When a device is placed on a Qi-compatible charging pad or surface, the receiver coil in the device detects the magnetic field generated by the charging pad or surface. The receiver coil then converts the magnetic field into an electrical current, which is used to charge the device’s battery. The Qi standard uses a feedback loop to regulate the amount of energy transferred between the charging pad or surface and the device, ensuring that the device is charged safely and efficiently.
