Step 13: Determine the charging mode of the electronic device according to the authentication result, wherein the charging power for charging the battery is different in different charging modes.

In the embodiment of the present disclosure, the first encryption authentication may be performed in the authentication system of the electronic device. The authentication system can be a device system. Because the device system may be an open source system. When performing the first encryption authentication in the device system, there is a risk of being deciphered. Therefore, performing the second encryption authentication includes sending authentication information associated with the battery to the cloud server and receiving the authentication result fed back by the cloud server. According to the authentication result, the charging mode of the electronic device is determined. The cloud server can authenticate the authentication information and obtain an authentication result indicating whether the battery is an authorized battery. Electronic devices can include mobile phones, tablets, laptops and other electronic devices. Device systems include mobile operating systems such as Android systems.

In the charging method of the electronic device in the embodiment of the present disclosure, the battery of the electronic device has an encryption unit. The charging method includes: performing a first encryption authentication on the battery through the encryption unit, wherein the first encryption authentication is used to determine whether the battery is an authorized battery. Perform authentication; when the first encryption authentication passes, send authentication information to the cloud server, where the authentication information is associated with the battery; receive the authentication result fed back by the cloud server, where the authentication result is determined based on the authentication information, and the authentication result is used Indicates whether the battery is an authorized battery; based on the authentication result, the charging mode of the electronic device is determined. The charging power for charging the battery is different in different charging modes. In this application, when the first encryption authentication is passed, the second encryption authentication is performed, which includes sending authentication information to the cloud server, and determining the charging mode of the electronic device through the authentication result of the authentication information by the cloud server. Since the second encryption authentication authenticates the authentication information in the cloud server, the corresponding information used in the authentication process is not easily cracked by the calculator, thereby reducing the probability of the battery encryption being cracked.

In the embodiment of the present disclosure, the first encryption method and the second encryption method are different, which may include: the encryption unit or encryption address of the first encryption method is different from the encryption unit or encryption address of the second encryption method, which may also include the first encryption method. The public key and private key used for encryption and decryption in the second encryption method are different from the public key and private key used for encryption and decryption in the second encryption method. When the first encryption authentication is passed, the battery is encrypted and authenticated based on the second encryption method, thereby reducing the probability that the battery encryption is cracked.

In this disclosed embodiment, the first public key and the first private key used in the first encryption method are different from the second public key and the second private key used in the second encryption method. That is, the first public key is different from the second public key, and the first private key is different from the second private key.

In this disclosed embodiment, the first public key is stored in the authentication system of the electronic device, and the first private key is stored in the encryption unit of the battery. The public key is stored in the cloud server, and the second private key is stored in the encryption unit of the battery. When the first encryption authentication is passed, performing the second encryption authentication includes performing encryption authentication on the battery based on the second public key and the second private key. Since the second encryption authentication is performed on the cloud server through the second public key, and the second public key is stored in the cloud, and only the administrator has the authority to know it, the second public key used in the authentication process is not easily cracked by the calculator, so It can reduce the probability of battery encryption being cracked.

Get the first character code;

In the embodiment of the present disclosure, the first character code may be a string containing data and letters, and may be randomly generated by the device system. The first public key and the first private key may correspond based on the first encryption rule. In the device system, the first public key encryption can be performed on the first character code to obtain the first ciphertext. The encryption unit of the battery can decrypt the first ciphertext through the first private key decryption to obtain the second character code, where the second character code is different from the first character code. When the first character code matches the third character code, it is determined that the first encryption authentication of the battery has passed. At this time, it means that the battery may be an authorized battery, or it may be because the first encryption authentication has been deciphered. . Therefore, a second encryption authentication is required.

If the third character code does not match the first character code, then the third character code and the first character code are character codes that do not comply with the same predetermined rule. For example, the predetermined rule is that the character code is 6, which is a string, and the order is the interval setting between letters and numbers. For example: q1w1e3, and a1s2f3 are both 6 is a string, and the order is the interval setting between letters and numbers. At this time, it can be considered that q1w1e3, and a1s2f3 conforms to the character code under the same predetermined rule.

The two-character code is encrypted to obtain the authentication information. The authentication information is transmitted to the cloud server through the authentication system.

In the embodiment of the present disclosure, when the charging mode of the electronic device is determined through the authentication result, the authentication result may indicate that the battery is an authorized battery or an unauthorized battery. If the authentication result determines that the battery is an authorized battery, it is determined to charge the electronic device in the first charging mode; if the authentication result determines that the battery is an unauthorized battery, it is determined to charge the electronic device in the second charging mode. The electronic device is charged. The first charging mode can be understood as a fast charging mode, and its corresponding charging power is the first charging power. The second charging mode can be understood as a normal charging mode, and its corresponding charging power is the second charging power. Determining the charging mode through the certification results can help reduce the situation of rapid charging of disguised batteries (i.e. unauthorized batteries), thereby reducing the risk of battery fires caused by non-compliant charging.

In the embodiment of the present disclosure, the predetermined time is the length of the validity period of the battery being charged in the first charging mode after being authenticated by the cloud server as an authorized battery. When the authentication result determines that the battery is an authorized battery, the battery can be charged directly with the first charging power within a predetermined time, and there is no need to perform authorization verification on the battery. But after a predetermined time, re-certify whether the battery is an authorized battery. When the predetermined time has elapsed, before re-certifying whether the battery is an authorized battery, the second public key and the second private key used for encryption authentication are updated to increase the effectiveness of the re-certification.

In some embodiments, the charging method further includes:

In this disclosed embodiment, when the first encryption authentication is passed and the authentication result fed back by the cloud server determines that the battery is an unauthorized battery, it can be determined that the first encryption authentication of the battery has been cracked. The first public key and the first private key need to be updated to increase the effectiveness of the first encryption authentication.

In this disclosed embodiment, since the second encryption authentication requires sending authentication information to the cloud server, the electronic device needs to determine whether the electronic device has established communication with the cloud server before performing the second encryption authentication after passing the first encryption authentication. connect. After the electronic device establishes a communication connection with the cloud server, the authentication information is sent to the cloud server.

In some embodiments, the charging method includes:

For example, the first charging power is a fast charging power of 120 watts, the second charging power is a slow charging power of 5 watts, and the third charging power may be 15 watts.

Upload the tag information of the disguised battery to the cloud server.

In the embodiment of the present disclosure, when the authentication result fed back by the cloud server determines that the battery is an unauthorized battery, the battery can be marked as a disguised battery. Tag information may include tag number, tag barcode, etc. Mark the disguised battery with a specific marking number or marking barcode for identification by the authentication system, and upload the marking information of the disguised battery to the cloud server for recording.

In some embodiments, the charging method further includes:

In this disclosed embodiment, when the authentication result fed back by the cloud server determines that the battery is an authorized battery, and the battery is charged for the second time, it is necessary to determine whether the verification passing time exceeds a predetermined time. When the time for passing the verification does not exceed the predetermined time, the validity of the passed verification is delayed. For example, the predetermined time is determined to be one month, and when the battery determined to be authorized is charged for the second time, as long as the authorization time to the second charging time is within one month, it is determined that the time to pass the verification does not exceed the predetermined time. At this time The validity of said verification pass may be delayed. That is, no authorization verification is required when charging for the second time.

Step 21: Verify whether the battery of the electronic device is an authorized battery through the authentication information, and obtain the authentication result;

Step 22: Feed back the authentication result to the electronic device.

In this disclosed embodiment, the cloud server can authenticate the received authentication information to verify whether the battery of the electronic device is an authorized battery. For example, if the cloud server can authenticate the received authentication information successfully, then it can be verified that the battery of the electronic device is an authorized battery; or if the cloud server cannot authenticate the received authentication information, it can be verified that the battery of the electronic device is an authorized battery. Unauthorized battery. Feeding back the authentication result to the electronic device means feeding back the result of whether the battery is an authorized battery to the electronic device. In this application, since the authentication work of the authentication information is completed by the cloud server, the corresponding information used in the authentication process stored in the cloud server is not easily cracked by the calculator, thereby reducing the probability of the battery encryption being cracked.

In this disclosed embodiment, when the cloud server authenticates the authentication information, the authentication information can be decrypted using the second public key in the cloud server to obtain the fourth character code.

At this time, the matching of the fourth character code and the first character code may include: the fourth character code and the first character code are both character codes that comply with the same predetermined rule, for example, both are character codes with the same order of letters and numbers. If the fourth character code does not match the first character code, then the fourth character code and the first character code are character codes that do not comply with the same predetermined rule. For example, the predetermined rule is that the character code is 6, which is a string, and the order is the interval setting between letters and numbers. For example: q1w1e3, and a1s2f3 are both 6 is a string, and the order is the interval setting between letters and numbers. At this time, it can be considered that q1w1e3, and a1s2f3 conforms to the character code under the same predetermined rule.
