When the terminal device is located in the charging area of the charging device, the magnet change condition detected by the terminal device or the charging device can be used, and when the detected magnetic field change condition meets a certain condition, the handshake success between the terminal device and the charging device can be determined, namely the terminal device is located in the preset area of the charging area. The distance between the terminal device and the charging area of the charging device can also be detected, for example, when the distance is less than a certain value, it can be determined that the handshake between the terminal device and the charging device is successful.

In this case, the first magnet may be controlled to operate at a first power with a first predetermined power value, so that the first magnet has a certain magnetic attraction force. In addition, in this case, the charging device may further send first information, where the first information is used to indicate that the second magnet, which is an electromagnet, operates with power whose power is a third preset power value, and the third preset power value is set to be greater than the first preset power value, that is, the second magnet generates a larger magnetic attraction force, so that a strong attraction alignment is performed between the second magnet and the first magnet, and the purpose of aligning the first charging coil and the second charging coil is achieved.
When the electric quantity of the terminal equipment is higher than or equal to the preset electric quantity, the first power is set to be the second preset power value, so that the first magnet works with the first power with the power being the second preset power value, the first magnet and the second magnet are subjected to once strong adsorption alignment, and the aim of aligning the first charging coil and the second charging coil is fulfilled.

For example, when the adsorption alignment time is set to 1 second, after the first magnet is controlled to work at the first current for 1 second, the adsorption alignment of the first device and the second device is determined, and then the adsorption current of the first magnet is reduced, so as to reduce the unit energy consumption of the first magnet in the charging process of the terminal device.
For example, when the first device and the second device perform adsorption alignment, the magnitude of the working current required by the first magnet is I1And after the first device and the second device are in adsorption alignment, the magnitude of the working current required by the first magnet is I2Wherein, I2Is less than I1Thereby reducing the unit energy consumption of the first magnet in the charging process.
