In this step, 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 may be used, and when the detected magnetic field change condition satisfies a certain condition, it may be determined that the handshake between the terminal device and the charging device is successful, that is, 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 may also be detected, for example, when the distance is less than a certain value, it may be determined that the handshake between the terminal device and the charging device is successful.
The first unlocking information can be fingerprint information, face feature information, pupil information and the like. Fingerprint information of a user can be collected through a fingerprint module arranged on the charging equipment; or, the face feature information or the pupil information of the user is acquired through a camera arranged on the charging equipment.

If the first unlocking information is successfully matched with the preset unlocking information, it can be indicated that the terminal device is controlled by the owner. Then, can work with first power through controlling the second magnet to make the second magnet produce magnetic field, and possess the magnetic adsorption power, and carry out magnetic force to the first magnet that sets up on terminal equipment and adsorb the counterpoint principle, so that charging equipment and terminal equipment adsorb the counterpoint, and make charging equipment's second charging coil and terminal equipment's first charging coil reach the purpose of adsorbing the alignment, thereby improve charging equipment to terminal equipment's charge efficiency.
Wherein, can work with great first power through controlling the second magnet to increase the magnetic attraction of second magnet to first magnet, thereby make first charging coil and second charging coil reach the purpose of full alignment.
Moreover, the magnetic force adsorption of the first magnet and the second magnet can achieve the purpose of adsorption alignment, reduce the gap between the charging equipment and the terminal equipment, shorten the transmission distance of electric energy and improve the transmission efficiency of the electric energy.
The relative distance between the geometric center of the first charging coil and the first magnet is equal to the relative distance between the geometric center of the second charging coil and the second magnet, and the second magnet on the charging device is arranged corresponding to the position of the first magnet on the terminal device.
And 403, after the charging device and the terminal device are in adsorption alignment, transmitting electric energy to the terminal device through a second coil of the charging device so that the charging device charges a battery of the terminal device.
In this step, the terminal device is provided with a first charging coil, the charging device is provided with a second charging coil, and electric energy can be transmitted to the first charging coil through the second charging coil so as to charge a battery of the terminal device.
And if the charging equipment starts to charge the battery of the terminal equipment, the second indicator lamp can be controlled to be lightened so as to remind the user that the terminal equipment enters the charging state.
Therefore, whether the charging operation of the terminal equipment is executed or not is determined by acquiring and identifying the unlocking information of the user, and the safety and the interactivity of the charging process can be effectively improved; and through adsorbing counterpoint with the first magnet on the terminal equipment and the second magnet on the battery charging outfit to make the first charging coil on the terminal equipment aim at with the second charging coil on the battery charging outfit, can also improve battery charging outfit to terminal equipment's power transmission efficiency, and then improve the charge efficiency to terminal equipment.

In this embodiment, after the terminal device enters the charging state, the second indicator light of the charging device may be controlled to emit light of the first color to remind the user.
Before the terminal device and the charging device perform handshake communication, unlocking information of the owner, such as fingerprint information or face feature information, can be stored on the charging device, and after the owner successfully stores the unlocking information, the second indicator lamp can emit light of a fourth color; then, when the charging device enters a state of starting to charge the terminal device, the light color of the second indicator light may be controlled to be converted from the fourth color to the first color, for example, yellow-charging to green-charging.
Optionally, after the controlling the second indicator light to emit the light of the first color, the method further includes: acquiring second unlocking information acquired by the charging equipment; if the second unlocking information is successfully matched with the preset unlocking information, interrupting the magnetic adsorption force between the first magnet and the second magnet, and controlling the light color of the second indicator light to be converted from the first color to the second color; and if the second unlocking information fails to be matched with the preset unlocking information, increasing the magnetic adsorption force between the first magnet and the second magnet, and controlling the light color of the second indicator light to be converted into a third color from the first color.
In this embodiment, fingerprint information or face feature information may be collected, and comparison and matching may be performed based on the collected fingerprint information or face feature information and pre-stored unlocking information (including pre-stored fingerprint information or pre-stored face feature information), and if matching is successful, it is determined that unlocking is successful; and if the matching fails, determining that the unlocking fails.
If the unlocking is successful, the power supply to the second magnet is interrupted, if the first magnet is also electrified, the power supply to the first magnet can be interrupted simultaneously, so that the magnetic adsorption force between the first magnet and the second magnet is relieved, and a user can take the terminal equipment away; if the unlocking is failed, the current unlocking object is determined to be not the owner of the terminal equipment, and at the moment, the magnetic adsorption force between the first magnet and the second magnet can be increased to prevent the non-owner user from taking away the terminal equipment.
When the unlocking is successful, the light color of the second indicator light can be controlled to be converted from the first color to the second color, for example, from yellow to blue, so as to remind the user that the magnetic attraction force between the terminal device and the charging device is relieved, and the user can take the terminal device away; in case of a failed unlocking, the light color of the second indicator light may be controlled to be switched from the first color to a third color, such as yellow-filled to red, to warn the non-owner user to prevent the terminal device from being taken away by the non-owner user. Through the setting of pilot lamp to according to the change of pilot lamp colour, can remind the specific state of user's battery charging outfit in the charging process, and promote user's the experience of charging.
When the magnetic adsorption force between the first magnet and the second magnet is increased, the working power of the first magnet can be increased, the working power of the second magnet can be increased, and the magnetic adsorption force between the first magnet and the second magnet can be increased by increasing the magnetic adsorption force of the first magnet and/or the second magnet, so that the aim of preventing the terminal equipment from being taken away is fulfilled.
If the unlocking failure times exceed the preset times, the current unlocking user can be warned in an alarm sending mode, meanwhile, the reminding information can be sent to other binding equipment of the owner, the camera can be started to collect the video of the current unlocking user, and the evidence is stored. Optionally, the preset times may be set to 2 times, 3 times, and the like, and the setting of the preset times may be set according to the habit of the user.
Therefore, the problem that the terminal equipment is taken away by a stranger in the charging process can be effectively solved by encrypting the charging equipment; moreover, through in the charging process, encryption and unlocking are added, and the operation experience of a user can be improved.
Optionally, before controlling the second magnet to operate at the first power, the electric quantity of the terminal device may be acquired, and the magnitude of the first power is controlled according to the electric quantity of the terminal device; if the electric quantity of the terminal equipment is detected to be lower than the preset electric quantity, the second magnet can be controlled to work at a higher power, and meanwhile, the first magnet of the terminal equipment is controlled to work at a lower power, so that the magnetic adsorption alignment of the first magnet and the second magnet is realized; if the detected electric quantity of the terminal equipment is higher than or equal to the preset electric quantity, the second magnet and the first magnet can be controlled to work at normal working power so as to meet the requirement of magnetic adsorption alignment of the first magnet and the second magnet. Therefore, the aim of aligning the first charging coil of the terminal device with the second charging coil of the charging device is fulfilled.
Optionally, in the adsorption alignment process of the terminal device and the charging device, adsorption alignment time of the terminal device and the charging device may be set. For example, when the adsorption alignment time is set to 1 second, after the first magnet is controlled to operate at the first current for 1 second, it is determined that the terminal device and the charging device are in adsorption alignment, 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 terminal device and the charging device perform adsorption alignment, the magnitude of the working current required by the first magnet is I1And after the terminal device and the charging 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.
Optionally, information interaction between the terminal device and the charging device may be performed through modes such as two-dimensional code scanning verification, bluetooth communication, WIFI communication, NFC communication, and the like, as long as information interaction between the terminal device and the charging device can be achieved.
It should be noted that, the first indicator light of the terminal device may also be controlled to emit different colors of lights to remind the user of the state of the terminal device, such as the charging state, the abnormal state, or the preparation state, and the implementation manner of the first indicator light is similar to that of the charging device, and is not described herein again.
