aholmesWhat is Wireless Charging?
Wireless charging, also known as inductive charging, utilizes an electromagnetic field in order to transfer energy between two objects. Recently, inductive charging technology has been modified to meet the growing needs of an increasingly technologically reliant generation of consumers. Wireless charging technology is not necessarily a new advancement since its origins can be traced to almost a century in the past, but only recently have businesses been able to harness wireless charging technology in order to create products that consumers will rely on for years to come.
The History of Wireless Charging
Wireless charging may seem like a recent technological advancement, but the science governing inductive charging was discovered in 1891 by Nikola Tesla. Nikola Tesla harnessed the power of wireless inductive charging to bring power to two light bulbs. The light bulbs were placed in close proximity to a grouping of coils that were connected to a power source capable of generating an electromagnetic field. Despite its application in 1891, it was many years before this technology was transitioned into a viable consumer product capable of being sold for profit. The roots of wireless charging are in Nikola Tesla’s original findings, but their application has developed in accordance with the modernization of technology.
While it may seem like wireless technology has only been available in recent years due to mobile electronic device usage, it has actually been being used in consumer products for quite a bit longer. Many people do not realize that common items like electronic toothbrushes, razors, and household wireless phones all utilize wireless charging technology to function. For items in environments that are exposed to water, wireless charging can be a safer option, which is why it was adopted for use in electronic toothbrushes and razors. All of these items utilize a charging dock to remain powered up and available at the discretion of the user. After each use, these items are placed back on their charging dock and this ensures that consumers are never without a charge. As technology has advanced far past household phones and electronic toothbrushes, so have the adaptations for wireless charging technology.
One of the most common devices consumers are used to seeing wireless technology developed for is mobile electronic devices. The majority of people in modern society rely on their handheld mobile phone in order to do much more than just make calls, which makes it vital for individuals to be able to rely on having a constant battery charge. Many people rely on their devices to stay in touch with work, connect with social media, check incoming emails and messages, communicate with loved ones, colleagues, and clients, and utilize apps to find their way and purchase goods. The possibilities of how much a handheld mobile device can mean are truly limitless in our modern technological landscape. Seeing this niche develop, companies have been quick to develop new and advancing technology to accommodate the needs of an increasingly technologically reliant culture. In addition to wireless charging technology being harnessed for mobile devices, it has also been advanced in a number of other diverse fields. Wireless charging has been utilized in everything from transportation to watches to surgically implanted devices. Wireless charging may not be a new technology, but the possibilities of how it can affect the modernization and ease of future technological developments is limitless. Now that you have a brief understanding of how wireless charging has evolved over time, it is necessary to look at precisely how wireless technology works.
The Inner Workings of Wireless Charging
In order to understand wireless charging, it is necessary to examine how the charging current is generated and maintained. Wireless charging utilizes the principle of magnetic resonance to generate the energy to recharge a battery. Magnetic resonance is also sometimes referred to as Inductive Power Transfer (IPT). Inductive Power Transfer occurs when an electrical current is transferred between two objects using coils to create an electromagnetic field. There are five key steps that comprise the process of wireless charging:
The voltage from the transmitter is converted into a high frequency alternating current (AC).
Once the high frequency alternating current is generated, it is directed to a transmitter coil by the transmitter circuit. From there, the alternating current can create a time varying magnetic field in the transmitter coil.
After the alternating current successfully generates a time varying magnetic field within the transmitter coil, the alternating current within the transmitter coil generates a magnetic field that is capable of extending to the receiver coil (provided it is within a specified distance).
Once this magnetic field is generated within the received coil, a current is established within the receiver coil of the receiving device. The process in which the transmitter coil and receiver coil flow energy between them is known as magnetic or resonance coupling. Magnetic or resonance coupling gained its name because in order for this flow of energy to successfully occur, both coils must be resonating at the same frequency.
Once the current is established between the transmitter coil and the receiver coil, the current flowing within the receiver coil is capable of being converted into a direct current (DC) by the receiver circuit. Once this direct current begins flowing into the receiver circuit, the battery of the device will begin to be charged.
How Wireless Charging is Evolving
In recent years, wireless charging has become integrated into a number of different devices and fields. One of the most well-known applications of wireless charging developed is for smartphones and mobile electronic devices. The number of mobile phone companies taking advantage of this new technology has steadily grown in recent years as various brands and businesses have attempted to carve out their own space in the wireless charging sphere. One of the most well-known types of inductive charging systems worldwide is Qi, which is utilized in over 900 products worldwide and was developed by the Wireless Power Consortium. Once you begin delving into the world on wireless charging, it is only a matter of time before you come across Qi and other types of similar technology.
Despite mobile phone technology being one of the most well-known and rapidly growing industries utilizing wireless charging, it is not the only one to consider. In recent years, car manufacturers have been steadily producing more electric cars and are now looking into how electric cars can benefit from wireless charging technology. Imagine a world where you could drive from one place to the next and only ever stop to charge for a short time before continuing on. This is the world that vehicle manufacturers are steadily working towards.
In addition to car companies, wearable technology manufacturers are also looking to capitalize on the substantial benefits that wireless charging technology offers. One of the factors that can prove to be a challenge when developing wireless charging solutions for wearable technology is the much smaller size of most products and the huge spread of different products currently on the market. However, companies are working to make a solution that meets the needs of wearable technology users in the same way that charging pads have increasingly met the needs of electronic mobile device users.
The Benefits of Wireless Charging
Wireless charging offers a number of benefits to consumers which is why it is becoming increasingly popular. One of the most important benefits of wireless charging is that it offers a much higher level of convenience than traditional direct charging. There are many everyday scenarios in which the average person could benefit from having a wireless charging pad. One example of a situation in which wireless charging is much more convenient is when traveling. No one wants to dig through their packed bag to find their charging cable and then search around an airport to find an open socket.
Wireless charging hubs have brought an unprecedented level of convenience to travelers looking to charge up their devices before heading on their way. Another example of how wireless charging adds convenience is when answering a call, text, or email while your phone is charging. Typically, it would be necessary to unplug your phone, then answer your call, text, or email, and then plug back in the cord to begin charging again. Wireless charging pads eliminate the need to do this by having an easy, convenient area where you can pick your phone up and merely set it back down when done rather than fumbling around with a cable.
In addition to being more convenient., wireless charging can also significantly reduce the number of cords you need at any given time. Rather than needing a cord connecting your device to the charger which is connected to the socket, you only need to plug the wireless charging pad into the socket and then set your device down on it. In addition to reduce the need for extraneous cords, wireless charging also gives you the capability to charge multiple devices at once.
Without the need for a mess of cords and tangled confusion, you will be able to charge multiple devices at once without any hassle. In addition to just being more convenient, wireless charging is also considered to be safer due to the elimination of the charging cable. Charging cables can become frayed due to heavy use, which presents a potential fire hazard. When the insulation surrounding the cables becomes frayed from frequent use, the current running between the cables has the potential to arc, which can fray or burn the insulation.
In addition to merely damaging the insulation, these weaknesses can also present a formidable shock risk that could be potentially dangerous. Wireless charging eliminates these hazards and provides a safer alternative option. In addition to this, wireless charging also eliminates the need for many traditional charging cables, which over time will reduce the waste created by the constant need for new charging cables.
The final benefit of wireless charging is its role in the future. Many companies are expanding their enterprises to include wireless charging hubs to draw in customers and keep them satisfied. Wireless charging hubs can make a significant difference in places like airports, universities, major businesses, and libraries, among others. Those businesses with an eye to the future are planning on investing their energy and resources into keeping you charged up and ready to take on the day, which is why they are focusing their efforts in developing wireless charging hubs in convenient locations to help make it unnecessary to ever go without a charged battery.
It is forecasted that technology users should anticipate wireless charging becoming more integrated into the current technological landscape and to begin seeing a phasing out of traditional direct charging methods. Just as before DVD’s there was VHS, now charging is moving steadily away from the methods of the past and charging cables into a future of wireless charging pads and docks.
