Is Wireless Charger Hurting The Phone?

The wireless charger will not harm the mobile phone under normal circumstances. The current working frequency of wireless charging is below 1M, so it will not affect the signal of the mobile phone. Wireless charging also has no impact on the battery life of mobile phones. It is basically the same as wired charging and the wireless charger's electrical energy conversion rate is still very high, resulting in more energy-saving. Wireless chargers mainly use inductive coupling technology. Because of the coupling technology, mainly through the coil's magnetic field to generate current, the battery's internal components can not constitute a magnetic field, so the internal structure of the battery will not be damaged during the power-on process. Most of the current mobile phones in the market conform to the QI wireless charging standard. A built-in wireless receiver has a rated voltage and current, so the wireless charger has no effect on the mobile phone

Future Technology Of Wireless Charging

Wireless charger has a wide range of use in the mobile phone charging range Work and experimentation is currently underway in designing this technology to be applied to electric vehicles. This will be implemented by using a predefined path or conductors that would transfer power across an air gap and charge the vehicle on a predefined path such as a wireless charging lane. Vehicles are already on the road that could take advantage of this type of wireless charging lane to extend the range of their on board batteries. Some of the issues that are currently preventing these lanes from becoming widespread is the initial cost associated with installing this infrastructure that would only benefit a small percentage of vehicles currently on the road. Another complication is tracking how much power each vehicle was consuming /pulling from the lane. Without a commercially way to monetize this technology many cities have already turned down plans to include this lanes in their public works spending packages. However this doesn’t mean that cars are unable to utilize large scale wireless charging. The first commercial steps are already being taken with wireless mats that allow electric vehicles to be charged without a corded connection while parked on a charging mat. These large scale projects have come with some issues which include the production of large amounts of heat between the two charging surfaces and may cause a safety issue. Currently companies are designing new heat dispersion methods to combat this excess heat this includes most major electric vehicle manufactures such as Tesla, Toyota, and BMW.

Why Wireless Charging Tech Is Up In The Air

As our dependence on smartphones escalates, we become slaves to their batteries. They beg for our attention as their power dwindles, and we come running with cables, chargers and power banks. Over the past few years, wireless charging pads have sought to relieve some of that stress by helping us repower batteries without having to plug anything in, but their development has been marked by problems: competing standards, incompatibility issues and slow charging times. In the past six months, however, there have been a number of shifts within the industry that could transform wireless charging from a neat gimmick into a crucial element of future technology. A pivotal moment happened in September, when Apple announced that AirPower, its own wireless charging pad, would be released in 2018. That product still has not been given a release date, but its announcement revealed that Apple had chosen a wireless charging standard known as Qi (pronounced “chee”) over its main competitor, AirFuel. “It reduced uncertainty for everyone,” says Menlo Treffers, chairman of WPC, the consortium of companies behind Qi. “With Apple and Samsung both supporting the same standard, this was a message of compatibility.” Qi was henceforth crowned the winner of that particular format war, and consumers can now be confident that if their device supports wireless charging, and there is a wireless charging pad near by, then the two will probably work together. AirPower is something of a misnomer, as all Qi chargers work via a process of electromagnetic induction rather than “over the air”. Both the device and the charging pad are equipped with coils that interact when placed next to each other, creating a current that allows the transfer of wireless power. Back in 2010 that power could reach only about 2.5W, but 5W is now common – ie, the same as a standard phone charger. With the advent of 7.5W and even 10W systems by the likes of Samsung and LG, we now have wireless chargers that are not only convenient, but work faster than the charger supplied with the phone. According to Treffers, such improvements will come thick and fast as more companies join the consortium (it’s up from 220 in September last year to 526 today). “It has introduced a lot of momentum, new initiatives and new features,” he says. On the surface, the ability to charge a phone without a cable seems like a hyper-convenience that has minimal value. “Don’t underestimate the psychological effect of not having to use two hands to connect a charger,” Treffers says. “It appears to be marginal, but once you start doing it, it feels really different.

Here's How Wireless Charging Will Cook Your Steak

Picture this: You scoop some grains into your rice cooker, and press start. The rice bubbles away. You haven't plugged the cooker into a wall outlet at all. This kind of culinary black magic is the Wireless Power Consortium's (WPC) vision for a high-power wireless charger made specifically for kitchen appliances. Shown off at the CES show in January, the unnamed standard will supply up to 2,400 watts of power through inductive charging built into -- or beneath -- the countertop. wpc-qi-inductive-ktichen-charging Look closely and you can see the Qi logo on the charging surface below these appliances. World Power Consortium If this sounds at all familiar, it's because WPC is the organization behind Qi wireless charging -- pronounced "chee" -- the protocol supported by phones from Samsung, Apple and LG. While wireless charging has been available to phones for years, companies want to take the technology beyond your handset, using wireless charging to power up laptops, fitness bands and yes, even kitchen appliances. Although we're seeing a push in the wireless charging space for transmitters that will recharge your devices over the air -- wireless power over distances of 15, 30 and even 80 feet -- the Wireless Power Consortium believes that its magnetic inductive charging, which only works over distance of a few millimeters, will deliver the strongest, safest surge of energy to a device.

Wireless Charging Is Meh, But It's Going To Get Way Better

This year's advances in wireless charging will help us ditch the cable. Advancement 1: One standard, with double the speeds Specifically, there is a company working on a new wireless charging standard that can power up phones more than 2.5 times faster than they do now. Today, we're looking at a maximum 15-watt output to wireless charging pads. Soon, we'll be able to charge phones at a maximum of 40 watts. This type of traditional wireless charging -- also referred to as contactless or inductive power -- is riding a big wave of momentum, thanks in large part to Apple's adoption of the Qi inductive power standard (pronounced "chee"), joining Samsung, LG and others. Up until last month, Powermat was Qi's biggest rival. But after Apple made its choice, Powermat decided that if it couldn't beat Qi, it would at least support it. Advancement 2: Charging at a distance Imagine that instead of sitting all the way on one side of the sofa so you can use your phone while it's tethered to a charger, you could sprawl out anywhere and still see your power reserves fill while you tap away? Companies are starting to bring over-the-air wireless charge to a bunch of devices. That means that your phone, fitness band, laptop and tablet could get a top-up just by passively resting on the shelf -- so long as it's a paired device, within range and in need of a top-up.

Are Inductive Wireless Chargers Safe?

We have a tendency to be scared of anything that emits ‘waves’ and ‘signals’, and we invariably presume that they must be harmful to us in some way (like a microwave oven, WiFi router, and even wireless phone charger). However, like most of the things listed here, inductive chargers are absolutely safe. safer-than-regular-smartphone-chargers-even-meme The electromagnetic field that an inductive charger creates is not strong enough to do any harm to humans. In fact, these chargers might even be safer than the regular ones, since they don’t operate with any wires, which means that you’re protected from even the tiniest chances of sustaining an electrical shock. Eminent scientist Nikola Tesla pioneered the idea in the late 1800s that power could be transmitted through an electromagnetic field between two objects. In effect, he had envisioned the concept of inductive charging almost two centuries before it came into existence. No wonder he’s dubbed ‘the man who invented the 20th century’!

Medical Implications Of Wireless Charger

Wireless charging is making an impact in the medical sector by means of being able to charge implants and sensors long term that are located beneath the skin. Researchers have been able to print wireless power transmitting antenna on flexible materials that could be place under the skin of patients.This could mean that under skin devices that could monitor the patient status could have a longer term life and provide long observation or monitoring periods that could lead to better diagnosis from doctors. These devises may also make charging devices like pacemakers easier on the patient rather than having an exposed portion of the device pushing through the skin to allow corded charging this technology would allow a completely implanted device making it safer for the patient. It is unclear if this wireless charger technology will be approved for use more research is needed on the safety of this devices. While these flexible polymers are safer than ridged sets of diodes they can be more susceptible to tearing during either placement or removal do to the fragile nature of the antenna that is printed on the plastic material. While these medical based application seems very specific the high speed power transfer that is achieved with these flexible antenna is being looked at for larger broader applications.

Is It Bad To Fully Charge Your Smartphone?

With greater ease of charging via wireless technology, the question becomes: Is it bad for your mobile device battery to be fully wireless charged all the time? Venkat Srinivasan, director of the Argonne Collaborative Center for Energy Storage Science (ACCESS), said that while you cannot overcharge a smartphone or tablet battery, as the electronics will not allow it, keeping it fully charged will hasten its degradation. "Frankly, the higher you are in the [wireless charging] state, as you creep up to 90%, 95% to 100% charge, the more degradation the battery will see," he said. As a lithium-ion battery charges and discharges, ions pass back and forth between a positive electrode (made of lithium-cobalt oxide or lithium iron phosphate) and a negative electrode (made of carbon graphite). As a battery charges, the positive electrode gives off lithium ions that move to the negative electrode and are stored as energy. As the battery discharges, those ions move back to the positive electrode to be used as electricity. As those lithium ions move back and forth, the electrolyte that acts as the transport medium degrades over time. The higher the state of charge, the faster the electrolyte degrades, Srinivasan said. Therefore, it's best not only to keep your smartphone below its top charge, but also to keep the charging and discharging pendulum from swinging wildly. "In general, if you swing the battery charge from top to bottom, that's the worst thing you can to for the life of the battery. If you can cycle the battery between 45% and 55% that's the best thing you can do," Srinivasan said. "But, in general, just make sure you don't keep it fully charged." Srinivasan also cautions against being too sensitive to your smartphone or tablet charging. Most smartphone manufacturers design batteries to last two to three years, so if you're a consumer who typically replaces your phone after that amount of time, you don't need to be overly concerned with charging rates.
