Wireless charging board and wireless charging method and system

Abstract

The invention provides a wireless charging board and a wireless charging method and system. The wireless charging board comprises a detector and a controller. The detector is used for obtaining wireless charging information corresponding to an external charging device when detecting that the external charging device is placed on the wireless charging board, and the controller is used for generating a charging coil matched with the external charging device below the external charging device according to the wireless charging information and wirelessly charging the external charging device. According to the wireless charging board, the wireless charging method and the wireless charging system, the wireless charging efficiency can be improved, and the power consumption waste can be reduced; the matching of the charging coil and the external charging device can be automatically realized without user operation, so that the user experience can be improved; and when a plurality of external charging devices are placed on the wireless charging board, a plurality of charging coils matched with the external charging devices can be generated according to the wireless charging information of the external charging devices, the process is simple, and wireless charging of the external charging devices can be achieved.

Description

technical field [0001] The present application relates to the technical field of charging, and in particular to a wireless charging board, a wireless charging method and a system. Background technique [0002] Wireless charging technology is a technology based on the principle of electromagnetic wave induction, applying AC induction technology, and using corresponding coils at the sending and receiving ends to send and receive induced AC signals for charging. The principle is as follows: figure 1 As shown, in practical applications, the user only needs to place the charging device on a wireless charging pad to charge it. [0003] In related technologies, in order to ensure the effective power of the wireless charging process, the coil of the wireless charging board will be made much larger than the coil of the charging device, resulting in waste of power consumption; in order to reduce the coil of the wireless charging board, some designs will be on the wireless charging boa...

Problems solved by technology

[0003] In related technologies, in order to ensure the effective power of the wireless charging process, the coil of the wireless charging board will be made much larger than the coil of the charging device, resulting in waste of power consumption; in order to reduce the coil of the wireless charging board, some designs will be on the wireless charging board Draw the charging area, but this requires the user to manually adjust the position of the charging device and the wireless charging pad to ensure optimal charging, but this process will increase user operations and poor user experience; in addition, most wireless charging pads only support a single coil for charging. Charging a single device cannot charge multiple devices. Even if the wireless charging board is equipped with multiple coils to support charging multiple devices, how to place the charging device to cooperate with the wireless charging board for charging will be more complicated.
