WCT( Wireless Charging Technology) is not a new technology.
In 1890, Nicola Tesla, who was a great inventor and physicist from Croatia, proposed a bold idea: Using the Earth as a conductor to establish low-frequency resonance between the Earth and the ionosphere. Using surface electromagnetic waves around the Earth to transmit electricity over long distances. And he tried to put this idea into practice.
Although the study was eventually terminated due to the withdrawal of funds and excessive risk factors, it opened the door to wireless charging technology.
In the following decades, the researchers followed Tesla’s footsteps and had a lot of exploration of this technology, and also made some achievements.
In June 2007, the MIT research team used electromagnetic resonators to light up a 60-watt electric bulb that was 2 meters away.
Japan Showa Aircraft Industry Corporation displayed a non-contact power supply system based on the principle of electromagnetic induction wireless transmission of electricity at 2009 AT International Exhibition.
In September 2010, Fujitsu Corporation of Japan wirelessly charges devices by magnetic resonance technology.
In July 2011, the first wireless charging electric vehicle was commissioned in Seoul Park, South Korea.
In September 2012, Nokia released two smartphones: the Lumia 920 and the Lumia 820, enabling wireless charging and sparking public attention to it.
At the Finnish Capital Airport in 2013, it provided free wireless chargers for passengers.
In March 2013, an Apple patent application entitled “Integrated Inductive Charging Technology for Protective Jacket” was published.
Now, wireless charging technology has made a quantum leap by the efforts of research teams and companies in major economic powers.It has evolved from the initial concept idea to the practicality of today’s life.
