The communication mode of present mainstream wireless charging technology has two main types of Carrier Modulation and Bluetooth Low Energy (BLE for short) technology. However, Carrier Modulation is very sensitive to circuit technology and electromagnetic environment, it is easy to be disturbed, thus easily leading to cannot charge the device properly； and BLE technology is mainly used in medium and long distance communication, it would generate false connection in short distance communication, also easily leading to cannot charge the terminal properly.
SUMMARY
The present disclosure provides a method for charging wirelessly, a device for charging wirelessly, a terminal and a computer readable storage medium, being capable of solving the problem that the terminal is not charged correctly because Carrier Modulation is easy to be disturbed and BLE technology is easy to generate false connection in present mainstream wireless charging technology.

DETAILED DESCRIPTION
Reference will be made in detail to embodiments of the present disclosure. The embodiments described herein are explanatory, illustrative, and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure.
What needs to be illustrated is: the terms “first” , “second” , etc. in Description, Claims and Description of the Drawings are used to distinguish similar objects, are not used to describe a particular order. In addition, the wireless charging of the present disclosure is near field tight coupling or loose coupling wireless charging.
A method for charging wirelessly provided by an embodiment of the present disclosure, based on a side of a device for charging wirelessly, includes followings as shown in Fig. 1.
102, a device for charging wirelessly transmits encoded authentication information to a terminal, in which, the authentication information includes a first identification code.
In some embodiments, the first identification code can be a string of numbers generated randomly by the device for charging wirelessly. The device for charging wirelessly generates and stores the first identification code.
104, the device for charging wirelessly receives feedback information transmitted by the terminal, in which, the feedback information includes a second identification code obtained by the terminal from decoding the authentication information received.
In some embodiments, after receiving the authentication information transmitted by the device for charging wirelessly, the terminal decodes the authentication information received so as to obtain the second identification code, then the second identification code is fed back to the device for charging wirelessly in the feedback information.
What needs to be illustrated is: if the terminal adopts the decoding mode corresponding to the encoding mode adopted by the device for charging wirelessly, the second identification code obtained by decoding the authentication information correctly is the same as the first identification code, and if the terminal decodes incorrectly, the second identification code may be different from the first identification code.
106, the device for charging wirelessly authenticates the second identification code according to the first identification code.
In some embodiments, the device for charging wirelessly can carry out comparing and matching the second identification code and the first identification code. What needs to be illustrated is that a possible mode of matching to authenticate is judge whether the first identification code is the same as the second identification code, but the present disclosure is not limited to this, there is another possible mode, for example, adding the two corresponding bits of the first identification code and the second identification code together, then judging whether the sum is the predetermined results, etc.
108, if the authentication success, the device for charging wirelessly begins to charge the terminal.
In some embodiments, when both sides of the device for charging wirelessly and the terminal interact through the authentication information and the feedback information, after the completion of the authentication process, the device for charging wirelessly begins to start a power transfer module for transmitting energy to terminal.
Furtherly, 102 can specifically include:
102a, the device for charging wirelessly encodes the authentication information.
In some embodiments, the device for charging wirelessly encodes the authentication information by a predetermined encoding mode.
102b, the device for charging wirelessly amplifies the encoded authentication information.
In some embodiments, normally, the signals generated by the device for charging wirelessly are weak and need to be amplified by an amplification circuit.
102c, the device for charging wirelessly carries out an impedance matching processing to the amplified and encoded authentication information.
In some embodiments, normally, the amplified signals after 102b also need to be matched with transmitter by an impedance matching circuit before to be transmitted.
102d, the device for charging wirelessly transmits the encoded, amplified and impedance matched authentication information to the terminal.
In order to guarantee high reliable communication quality of wireless charging, the encoding self-checking function can be added in 102a. If the self-checking is not successful, then 102a is repeated. If the self-checking is successful, the signals are transmitted to a closed loop signal  amplifier to perform 102b. Then it is checked whether the amplified signal is distorted. If the signal is not distorted, 102c is performed； if the signal is distorted, the closed loop signal amplifier regulates the bandwidth thereof according to a feedback, and then jumps back to perform checking whether the amplified signal is distorted again. The signal transmitting is completed by an impedance matching network after performing 102c, then 102d is performed.
Furtherly, the feedback information in 104 has been encoded.
As shown in Fig. 2, before 106, the method further includes followings.

Furtherly, an encoding mode includes an infrared encoding mode； correspondingly, a decoding mode includes an infrared decoding mode.
What needs to be illustrated is that the above infrared encoding and decoding mode are only a possible example； the present disclosure is not limited to this.
Furtherly, as shown in Fig. 2, before 102, the method further includes followings.
101, the device for charging wirelessly confirms the terminal within a charging range of the device for charging wirelessly through a preset induction mode； the preset induction mode includes one or more of a magnetic induction mode, an infrared induction mode, and an electric field induction mode.
In some embodiments, when the terminal needs to be charged, users put the terminal on the charging platform of the device for charging wirelessly, and then the device for charging wirelessly induces the terminal in its charging range through the magnetic induction mode, and then begins to perform 102. The aforementioned magnetic induction mode, infrared induction mode, electric field induction mode have been technologies in the related art and the technical principle thereof are no more described in detail in present disclosure.
The technical solutions of the present disclosure embodiments mentioned above are capable of avoiding the wireless charging device and the terminal being disturbed or generating wrong connection in wireless charging, so as to charge the terminal correctly.
The present disclosure also provides another method for charging wirelessly, based on a side of a terminal, as shown in Fig. 3, includes followings.

204, the terminal decodes the authentication information received and obtains a second identification code.
206, the terminal transmits feedback information including the second identification code to the device for charging wirelessly.
208, the terminal receives an authentication result of authenticating the second identification code according to the first identification code from the device for charging wirelessly.
210, if the result is authentication success, the terminal begins to accept to be charged by the device for charging wirelessly.
Furtherly, 206 specifically includes:

206b, the terminal amplifies the encoded feedback information.
206c, the terminal carries out an impedance matching processing to the amplified and encoded feedback information.

Overall, according to aforementioned two methods for charging wirelessly provided by embodiments of the present disclosure, the device for charging wirelessly broadcasts the authentication information to the terminal within the range of wireless charging platform, other than through the Carrier Modulation mode, thereby enhancing the anti-interference ability, meanwhile can also avoid generating influence to the terminal in the far field. The authentication of the device for charging wirelessly and the terminal is completed through the verification of the two identification code contained in the authentication information and the feedback information respectively, so as to accomplish the information communication interaction between the wireless charging transmitting end and receiving end, thereby solving the problem that the terminal is not charged correctly because Carrier Modulation is easy to be affected by circuit technology and  electromagnetic environment, and BLE technology is easy to generate false connection, and greatly improving the wireless charging communication efficiency and broadening the application range of wireless charging, and improving the user experience.

If the handshake acknowledgement signal transmitted by the terminal is received, then turn to S05； if the handshake acknowledgement signal transmitted by the terminal is not received, then turn back to S03.
