However, wireless charging systems in the market at present are based on Qi, the charging distance of the Qi wireless charging system is only 5mm-8mm, and most of thicknesses of table tops are generally between 15mm-30mm, so that the existing wireless charging products can be solved only by drilling holes under the table tops and embedding the wireless charger into the table, but the drilling holes not only damage the structure of the table and affect the appearance, but also consume manpower and man-hours. Meanwhile, the wireless charger is required to be arranged in a desk hole, so that popularization and application of the wireless charger in the aspects of office and home are greatly influenced. In addition, if the mobile phone is to be charged quickly, the transmitting end and the receiving end are required to complete authentication or binding, for example, the existing EPP architecture requires the transmitting end and the mobile phone end to complete both sides' identification and make a charging protocol, so that the quick charging (high power) can be realized. Under normal conditions, the modulation widths of bit "0" and bit "1" demodulated by the ASM are the same, but under abnormal conditions, the demodulated signal is easy to distort, and coils are different due to different mobile phones. The same coil has a high possibility of causing distortion of the demodulated signal if the charging distance or the charging placement position is different, resulting in slightly different demodulated signals. The traditional wireless charger cannot adapt to the differences, communication abnormity often occurs, the phenomenon that wireless charging cannot be achieved or charging is disconnected is caused, and charging experience is affected.
