Technology has developed a lot in the past decades but we cannot use any of these cutting edge devices if you don’t have the power to run it. Power is not a problem for devices that don’t run on a battery but have to be plugged in like desktops, TVs etc. But nowadays portable devices like smartphones, tablets, laptops, smart watches, which need a battery are more popular than ever. And we always struggle to last a day without charging these portable devices and need to find a charging port to charge our devices.
The world is waiting for a battery breakthrough. The energy that you store in batteries is limited and you cannot expect a battery to supply power for weeks. For decades consumer electronics battery run on Lithium-Ion battery because these batteries are easy to recharge. But experts say that now lithium-ion batteries are close to its saturation and scientists and engineers are working on finding out new methods to have a long sustainable battery.
Today we have methods through which we can charge our phone quickly. Qualcomm has introduced Quick Charge which charges the battery that can last 3-4 hours in just 5 minutes. Qualcomm has recently announced Quick Charge 4.0 that is 20% more efficient and 30% more efficient than Quick Charge 3.0. While Samsung has introduced Adaptive Fast Charging that not only is speedy, but it knows when to stop charging to prolong the life of your battery. Also, OnePlus came up with Dash Charging that, as the company claims, gives you a day’s power in half an hour”. This is the current scenario about charging your devices through cable and plug.
Now let’s talk about wireless charging.
Present State of Wireless charging.
Wireless charging is nothing but charging your device without plugging it in cable.
Wireless charging have officially entered into the market, companies like Samsung have started shipping wireless charging pads for their flagship devices.
QI wireless a tech company is selling its wireless charging pads and so many smartphone companies have their smartphones capable of charging wirelessly even if the company hasn’t officially announced it.
At the CES 2015 AirCharge announced an extended partnership with Mc Donald’s UK to install 600 QI Wireless charging hotspots around 50 Mc Donald’s store across UK.
Different types of Wireless Charging Methods.
There are 3 types of wireless charging methods:
Close range charging or the commonly known as inductive charging is the type of wireless charging which is commercially available in the market and it is highly efficient, cost-effective and easy to design. Typically close range wireless charging needs a charging pad on which the device is kept to charge.
Medium range charging uses resonance charging and it is expected to ready and available in the market very soon. This will be the next step to the larger future of wireless charging. Leading wireless charging companies like QiWireless and AirFuel Alliance are working on resonance charging.
3. Long Range
Long range charging is still under development and researchers are using a variety of different technologies like infrared rays and radio frequencies to make it successful. One of the tech company actually came up with a device which can charge your device wirelessly 15 feet’s away. Tech Giant Apple has been filing patent on wireless charging. Also the company announced a $200 million investment check here to find on what it was made!
Future of Wireless Charging
Other companies are taking the multi-mode approach much further, by supporting resonance on top of both inductive standards. NuCurrent is leading the way with components that supported Qi, PMA and AirFuel Alliance, and announced the world’s first 10 watts inductive and resonant charging antenna. At CES 2017, the company unveiled a number of new charging products designed for wearables, which support Qi and AirFuel standards at low and high frequencies.
Wireless charging is also branching out from its main purpose to become even more useful to consumers. The technologies have communication protocols built-in to ensure the correct power transfer between devices and this is being used for communication with other systems. For example, it can be used with smart home solutions, such as controlling lights or temperature.
So With all of these technologies on the horizon, we all are very excited about what the future holds and how these technologies will change our interactions with our devices and the environment around us.
Despite all of these why should consumers choose it over the convenience of a bedside USB cable?
