Wireless charging technology has a very long history, speaking of this technology dates back to 1901. In that year, there are two inventors get financier John Pierpont Morgan grant in New York, Long Island set up 187 feet (about 57 meters) high tower wireless charging - Worden Clif tower. Before this, they had conducted field trials in Colorado, successfully lit 25 miles (40 kilometers) outside the 200 lights. According to eyewitnesses, they can see in the feet and the ground electric spark jumps, in turn on the tap, but also a current with the water outflow. Although the project ended in failure, Tesla went bankrupt, but the charge is a pioneering work in the history of.
After a century of wireless charging technology thus ushered in a new source of power, the application range is very wide, small electric toothbrush, remote control, intelligent mobile phone, to electric vehicles, oil rigs. When it comes to the principle of wireless charging technology, has not many mysterious things, in some of the intelligent mobile phone has been achieved and commercialized. The principle of wireless charging is also very simple, in the transmitter converts electrical energy into electromagnetic wave and transmitted to the receiver, after receiving electromagnetic wave, and then convert it into electrical energy, it can be charged. There are three ways of realizing: electromagnetic induction, radio waves and magnetic resonance, three ways also have advantages and disadvantages.
