Wireless charging technology breakthrough interference bottleneck efficiency as high as 85%

According to foreign media reports, complex charging line often annoyed.

Fortunately, this problem is resolved from the source. Recently, in Osaka University of electronics, information and Communication Engineers convened a meeting, a research agency announced that Japan Wireless charging technology have made significant progress, the technology can also offer a variety of portable device charger.

Researchers have been trying to solve the Wireless charging technology, and has proposed a different solution.

However most of the programme only in a test phase, there are many technical problems cannot be resolved. The most popular of the two solutions is the electromagnetic induction and nuclear magnetic resonance. Electromagnetic induction relies on power transmission between the client and the receiving coil magnetic flux generated by. Although this is a future for electric vehicle charging of cutting-edge technology, but because it's small, but the scope for energy-and receive-side must be in the same line location, therefore greatly reducing the application flexibility. In comparison, the magnetic resonance method seems to be more flexible, because it can be from a single supply of electricity to multiple receivers provide energy, but not to consider the relative position of both parties.

Magnetic resonance method is good in theory, but in the actual design or had a great deal of trouble.

Not only parasitic capacitance and external magnetic fields, or even connect to your device can be disrupted and sufficient to electromagnetic fields, thus affecting charging efficiency. In addition, the smaller the more the device will be affected by external factors, makes this technology is very difficult to apply to the mobile phone.

Although a good charging system can reduce the impact of these factors, however, impede the Wireless charging technology development is the system design and analysis of related problems.

By their very nature, research institutions, researchers developed a model to coil and magnetic resonance of complex Simulator. The Simulator can help manufacturers set the charging system for the various parameters to improve charging efficiency.

Using this technology, Wireless charging cell phones can transmitter coverage anywhere charger, charging efficiency as high as 85%.

The research institutions that will use this technology to develop a wireless charger for mobile phone and other portable devices, and input in 2012.

The company also plans to develop a computer chip and electric vehicle wireless charging technology.
