while the device utilizing the energy to recharge is deemed the receiver. The most remarkable aspect of wireless charging is that this process can function without the use of a physical connection between the devices.
This allows users to be able to charge their devices without having to rely on a USB charging cable or available port space. In a world that is increasingly on the move both in industry, life, and at home, wireless charging is the future of maintaining battery life and connection to the technological world.
What is Wireless Charging?
Though wireless charging may seem like recent advancement, it has actually been being used for a variety of platforms for many years and is widely believed to have been discovered by Nikola Tesla in the late 1800’s. Despite the discovery of wireless power transfer (WPT) over a hundred years ago, it is only in recent years that the production of wireless charging products has reached a fever pitch. Some industries integrated wireless charging into their products years ago without most people realizing the technology they were utilizing. One of the most common household items people do not realize uses wireless charging technology is rechargeable electric toothbrushes. By harnessing wireless power transfer technology and implementing it into everyday uses that meet the technological needs of an advancing generation of electronics, many companies have been able to capitalize on a uanced utilization of familiar technology.
A Breakdown of How a Wireless Charging Pad Works：
Wireless charging utilizes electromagnetic fields in order to move power from one transmitting source into a specified receiving device to recharge the battery. As mentioned above, when attempting to understand how a wireless charging pad works, it is vital to keep in mind that the charging pad is a transmitter that is responsible for moving its charge into a receiver, such as a mobile device, in order for the receiver to recharge its battery. Wireless charging utilizes the principle of magnetic resonance to accomplish this transfer of power, sometimes referred to as Inductive Power Transfer (IPT). Inductive Power Transfer relies on coils to induce an electromagnetic field that is capable of transferring the electrical current between two objects without them needing to be physically connected. With this in mind, below are the steps that comprise the wireless charging process in order to offer a better understanding of how this technology functions.
Inductive Vs. Resonant Technology：
When discussing wireless charging technology, two terms often govern the discourse, those terms being inductive and resonant technology. From most perspectives, inductive and resonant technology exist in tandem. Inductive power transfer is the overriding principle that is foundational to achieving wireless charging. Inductive power transfer harnesses resonance in order to achieve the coupling between the transmitter and receiver coil, which is key to how the wireless connection can be attained. When the transmitter and receiver coil are coupled, both coils must resonate at the same frequency in order for the current to be established. However, recently there been a new term that emerged, known as resonant wireless charging.
