Abstract

The invention provides a wireless charging self-learning control method for long-distance self-adaptive FSK communication modulation and a wireless charger. A first characteristic value Q1 and a second characteristic value Q2 of a transmitting coil in a standby state are obtained, and when the first characteristic value Q1 is smaller than a certain set value, it can be determined that a repeating coil exists in a system. Then, the distance D1 between the transmitting coil and the repeating coil is calculated through an ingenious fitting formula D = b * eax, an FSK communication modulation depth parameter Tw capable of enabling a receiving end to accurately obtain the charging capacity of the transmitting end is obtained under the condition of D1, a weight value FTw corresponding to the Tw is increased, and D1, Tw, FTw and Q2 at the moment are recorded and set as a first mapping data set so as to be called and applied preferentially. When wireless charging is carried out again, charging parameters in the first mapping data set can be rapidly called to adapt to an EPP architecture, so that the wireless charging system can operate more quickly during wireless charging, the charging speed is increased, the charging time is saved, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of wireless charging, in particular to a wireless charging self-learning control method for long-distance self-adaptive FSK communication modulation and a wireless charger. Background technique [0002] Wireless charging is becoming more and more popular among household consumers because it can realize the wireless connection between the charging power supply equipment and the power receiving equipment, so that it can solve the problem of many and messy power lines on the desktop. However, the current wireless charging systems on the market are all based on Qi’s wireless charging system. Some wireless charging products need to drill holes under the desktop to embed the wireless charger into the table to solve the problem, but the drilling not only destroys the structure of the table, affects the appearance, but also consumes manpower and man-hours. At the same time, the need to drill holes on the desktop to...
