Our company decided to join the wireless charging alliance, introduce QI wireless charging technology, and develop the wireless charging market

Stepping into June 2013, in order to better supplement products, our board of directors decided to join the Wireless Power Consortium and become an ordinary member.

The Wireless Charging Alliance is a cooperative organization formed by a number of independent companies. The Wireless Charging Alliance is governed by the Alliance Charter, which stipulates confidentiality, intellectual property rights and decision-making.

The alliance is managed by a steering committee, and each permanent member has a seat in it. The chairman of the steering committee is Menno Treffers.

The technical specifications were created by the specification working group, and the working group meeting was chaired by the chairman Scott Mollema.

The Promotion Working Group is responsible for the communication between the alliance and the outside world, and its chairman is Camille Tang.

The technologies that have achieved wireless power transmission can be divided into three categories

Electromagnetic induction type.

Capacitive sensing type.

Magnetic resonance type.

Electromagnetic induction is the most mature technology. Its basic principle is to use the induction between two coils to complete the transmission of electric power. The cost is low, and it can be miniaturized.

The advantage of the capacitive induction type is that it is not sensitive to changes in the horizontal position of the electrical device, but due to the use of high frequency (several hundreds of KHz) and high voltage (1500V) currents to complete the transmission, the cost is high and it is not easy to achieve miniaturization , Not suitable for the use of micro-power wireless transmission.

Magnetic resonance technology can achieve long-distance power transmission, but its essential principle is to use the principle of induction between coils with extremely high Q values. Since it is impossible to produce coils with extremely high Q values, it cannot be realized in the short term. Commercialized and extremely large.
