The autumn, Samsung expected to release a wireless charging kit for its Galaxy S3 phone. After years of scrutiny, wireless is the latest plan to save the dying power cable of the phone.
Wireless charging, in fact, also known as inductive charging, its core is a conductive coil. That coil creates a magnetic field. If placed in close to a coil of similar size, the two resonance, creating a current without wires. This is the inductive charging.
Wireless power can reduce the demand for power cable, but also increase more durability of the product, eliminate the need of disposable batteries. “This is a very promising technology,” said Farouk Balouchi, an analyst for Pike, “is not a green technology, but it’s something that can help mobile devices become more energy efficient, environmentally friendly and sustainable.”
Here are several ways that wireless power transmission could change the world.
1) Kill the Power Cord.
Obviously, the advantages of wireless charging is, when go outside or at home, or away from the power supply can get rid of the power cord.
Power transmitter is usually installed on the surface. People take a long time to recharge. At first, just a few inches, the equipment in 5 watts of power or less work, such as bluetooth headsets. With the passage of time, the technology is more and more progress, so could be extended and energy.
Balouchi said:”Retail agencies may one day provide wireless charging as amenity free Wi-Fi, that was called ‘snacks charging’, could appear in airports, coffee shops , Banks and retail stores.”
From then on, power cord will never be used, never need to be processed, thus eliminating the sources of electronic waste.
2) Subvert the Disposable Battery.
Consumers have never use Battery charging equipment. You can’t beat the convenience of alkaline batteries, however, every year there are billions of cells into the landfill. Compared with wireless power, environmental protection rechargeable batteries will win against disposable products.
3) Make Charging an Electric Car Easier than Pumping Gas.
Some people suspect the electric car can withstand the long distance driving, or worry about electric power. Compared with the gas station work pressure, wireless power may alleviate this doubt. Several companies are developing a wireless hub for electric vehicle charging, including Witricity and Plugless Power.
Witricity has put the technology licensed to Delphi, the auto parts maker. More exciting, Stanford University and Utah State University researchers are working on a new project, that is embedded in the streets resonant coils, let your car drive itself. Wireless power, therefore, is not environmental protection, but it may become easier.
