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 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.
Wherein, under the successful condition of shaking hands with the battery charging outfit at terminal equipment, through the electric quantity that detects terminal equipment to judge whether the electric quantity of terminal equipment can satisfy that first magnet carries out once strong adsorption counterpoint, and then confirm the operating power of first magnet.
In this step, the target power of the first magnet may be determined based on the electric quantity of the terminal device, for example, if the electric quantity of the terminal device cannot satisfy the requirement that the first magnet performs strong adsorption alignment once, the first magnet may be controlled to operate at a lower power, and at the same time, indication information is sent to the charging device to indicate that the second magnet of the charging device operates at a higher power, so as to satisfy the requirement that the first magnet and the second magnet perform magnetic adsorption alignment; if the electric quantity of the terminal equipment can meet the requirement that the first magnet carries out strong adsorption alignment once, the first magnet is controlled to work with the power strength capable of meeting the requirement of magnetic adsorption alignment.
In the step, the first magnet is controlled to work at the target power so as to generate a magnetic field, and the first magnet has magnetic adsorption force so as to realize magnetic adsorption alignment of the second magnet of the charging equipment, and further realize adsorption alignment of the terminal equipment and the charging equipment.
Wherein, can work with great power through controlling first magnet, increase the magnetic attraction power of second magnet to first magnet to make first charging coil and battery charging outfit's second charging coil reach the purpose of full alignment.
And 504, after the terminal device and the charging device are in adsorption alignment, transmitting electric energy through the first charging coil so that the charging device charges a battery of the terminal device.
In this step, after the terminal device and the charging device are adsorbed and aligned, electric energy can be transmitted to the first charging coil of the terminal device through the second charging coil of the charging device, so that the battery of the terminal device can be charged.
In this embodiment, the working power of the first magnet can be determined according to the electric quantity of the terminal device, so as to avoid the problem that the alignment of the first magnet and the second magnet is not accurate enough when the electric quantity of the terminal device cannot meet the requirement of performing strong adsorption alignment for the first magnet.
Optionally, the determining the target power of the first magnet based on the electric quantity of the terminal device includes: if the electric quantity is lower than a preset electric quantity, setting the power value of the target power as a first preset power value; if the electric quantity is higher than or equal to the preset power value, setting the power value of the target power to be a second preset power value; wherein the first preset power value is smaller than the second preset power value.
In this embodiment, the working power of the first magnet may be determined by determining whether the remaining capacity of the terminal device can satisfy the requirement of performing the one-time strong adsorption alignment on the first magnet. Wherein, when can set for terminal equipment's electric quantity for predetermineeing the electric quantity, terminal equipment's electric quantity just in time can satisfy first magnet and carry out once the strong adsorption counterpoint to realize the alignment of first charging coil and second charging coil, improve terminal equipment's charge efficiency.
When the electric quantity of the terminal equipment is lower than the preset electric quantity, the residual electric quantity of the terminal equipment is not enough to perform strong adsorption contraposition once. In this case, the first magnet may be controlled to operate at a target power having a power level equal to a first predetermined power level, 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 target power of which the power is 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.
Optionally, in the process of charging the battery of the terminal device, if unlocking information is detected, whether unlocking is successful is judged, and if unlocking is successful, the magnetic adsorption force between the first magnet and the second magnet is interrupted; and if the unlocking fails, increasing the magnetic adsorption force between the first magnet and the second magnet.
In this embodiment, the fingerprint information or the face feature information may be detected, and the detected fingerprint information or face feature information is compared and matched with the pre-stored unlocking information (including the pre-stored fingerprint information or the pre-stored face feature information), and if the matching is successful, the unlocking is determined to be successful; and if the matching fails, determining that the unlocking fails.
Wherein interrupting the magnetic attraction force between the first magnet and the second magnet means terminating the magnetic attraction force of the first magnet to the second magnet. If the unlocking is successful, the power supply to the first magnet can be interrupted, if the second magnet is electrified, the power supply to the second magnet can be interrupted, 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.
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 terminal equipment; moreover, through in the charging process, encryption and unlocking are added, and the operation experience of a user can be improved.
