How Wireless Charging Pads Work
Wireless charging pads, also known as inductive charging pads, use electromagnetic fields to transfer energy between a transmitter and a receiver. This technology has been around for over a century, but it wasn’t until recent advancements in materials and design that it became efficient and safe enough for widespread use in consumer electronics.
The Science Behind Wireless Charging
The principle behind wireless charging is based on the concept of electromagnetic induction. When an alternating current (AC) flows through a coil of wire, it generates a magnetic field. If a second coil is placed within this magnetic field, an electromotive force (EMF) is induced in the second coil, causing a current to flow. This is the basic principle behind many electrical devices, including generators, motors, and transformers.
In the case of wireless charging pads, the transmitter coil is usually embedded in the charging pad, and the receiver coil is built into the device to be charged, such as a smartphone. When the device is placed on the charging pad, the transmitter coil generates a magnetic field, which induces a current in the receiver coil. This current is then used to charge the device’s battery.
Types of Wireless Charging
There are three main types of wireless charging: Qi (pronounced “chee”), PMA (Power Matters Alliance), and AirFuel. Qi is the most widely used standard, supported by companies like Samsung, Apple, and Google. PMA is used by companies like Starbucks and Powermat, while AirFuel is a newer standard that claims to offer faster charging speeds.
Qi wireless charging uses a resonant coil in the transmitter and receiver to improve efficiency and increase the distance over which energy can be transferred. This allows for faster charging speeds and the ability to charge devices through thicker materials, such as phone cases.
Benefits of Wireless Charging
