Wireless Charging Technology (WCT) is not an emerging technology. As early as 1819, Danish scientist Erst observed that if there is current on a wire, a magnetic field will be generated around it, which can deflect the north arrow. . Later generations further discovered that the wire is enclosed in a ring shape, even wound into a coil, and the generated magnetic field will be stronger and more concentrated. This is called "current magnetic effect".
In 1831, Faraday discovered that a magnet or other source of magnetic field was placed close to a coil without current, and an "inductive current" was generated on the coil, called "electromagnetic induction."
In 1890, Croatian inventor and physicist Nikola Tesla proposed a bold idea: using the Earth as a conductor, establishing a low-frequency resonance between the Earth and the ionosphere, using surround Earth's surface electromagnetic waves transmit power over long distances.
In 2004, Shuangfeiyan introduced a wireless mouse that was connected to the computer's USB interface via a wireless transmitter to obtain power.
In 2005, BYD applied for a patent for a non-contact inductive charger using electromagnetic induction technology. The City University of Hong Kong has developed a wireless charging platform for portable communication devices such as mobile phones and MP3s based on ICPT. Amway Home Water Purifier is the first to adopt Fulton wireless charging technology.
In September 2010, the Global Wireless Charging Alliance introduced the international standard for wireless charging in China.
In January 2013, Harbin Institute of Technology released a magnetic resonance wireless charging technology other than 1 m.
Wireless charging will gain more attention until 2018, and the recent MWC2018 (2018 World Mobile Congress) is the beginning. With the increasing number of smart devices and the popularity of wireless charging mobile phones, the construction of wireless charging infrastructure has also begun to be on the agenda. At present, wireless charging infrastructure in foreign countries has already reached a considerable scale. In China, we have also seen pilot airports in some places, airports, hotels, cafes and libraries. With the mass production of more mobile phones that support wireless charging, more wireless charging infrastructure will be built, when the mobile phone is immediately charging.
