AI Technical Summary

Problems solved by technology

[0006] The magnetic induction wireless charging device achieves the purpose of wireless energy transmission through the coupling of the electromagnetic field between the coils, but the technology realizes wireless charging at a short distance, and the horizontal movement of the coil will also cause a significant decrease in efficiency, and even charging cannot be realized. The experience is poor; the principle of the magnetic resonance wireless charging device is similar to the magnetic induction method. Although the horizontal displacement has relatively little effect on the efficiency, the charging distance is still relatively short.

That is to say, the use of the wireless charging method of the related technology is greatly affected by the distance, which limits the application of the wireless charging method of the related technology
