Detailed Description
Other features and advantages of the present invention will become more apparent from the following detailed description of exemplary embodiments of the invention, which proceeds with reference to the accompanying drawings.
Other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein. The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the drawings only show the components related to the present invention rather than the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
The first embodiment:
fig. 1 is a schematic overall flow chart of a battery management method according to a first embodiment of the present invention.
In the battery management method provided in this embodiment, the battery is used to supply power to the user equipment, and the battery management method is implemented by the battery management device on the battery side, where the specific battery management method includes:
and step S110, storing the key information. The key information comprises a user key, and the user key is a character string with a fixed length, comprises letters and numbers and can be used for identifying the identity of the battery.
And step S120, when the battery is detected to be connected with the user equipment, pre-discharging the battery. In this embodiment, the user equipment may be a vehicle terminal including, but not limited to, an antenna box. And identifying whether the battery is connected with the user equipment according to the change of the voltage of the battery. For example, when the voltage of the battery momentarily increases, it indicates that the battery is connected to the user equipment. At this time, the current is pre-discharged to operate the user equipment. The pre-discharging refers to charging the user equipment by adopting a small current. The method can prevent the user equipment from being incapable of authenticating with the battery when the power is off, and improve the anti-theft property.
Step S130, receiving the verification invitation sent by the user equipment and sending response verification information. When the battery is connected with the user equipment, the user equipment sends an authentication invitation to the battery, and when the battery receives the authentication invitation sent by the user equipment, the battery sends response authentication information. In this embodiment, the response verification information sent by the battery management device to the user equipment is a verification serial number, and the feedback verification information sent by the user equipment to the battery management device is a feedback serial number.
Step S140, receiving the feedback key information and the feedback verification information sent by the user equipment, and verifying whether the received feedback key information and the feedback verification information are legal. In this embodiment, the legal condition means that the feedback verification information sent by the user equipment is the same as the response verification information sent by the battery management equipment, and the feedback key information sent by the user equipment is the same as the key information stored in the battery management equipment. In other embodiments, other validation rules may be set to implement the authentication between the battery and the user equipment.
And S150, if yes, controlling the battery to discharge formally by the battery management equipment. When the user equipment identity is legal, the battery enters formal discharge from pre-discharge.
And step S160, if not, the battery management equipment controls the battery to stop discharging.
In this embodiment, the key information of the battery further includes a super key. The super key is equivalent to the unique identity key of the battery, so the super key can be generated only by the server, the server generates a corresponding super key by using an internal self-defining rule according to the ID number of the battery, the internal self-defining rule can be a common coding rule in the prior art, and a battery manufacturer can define the super key according to the battery condition and the battery batch number as long as a group of super keys can be generated and stored in the database;
in order to protect the super key, the super key is usually only known by the battery manufacturer, and the user key needs to be changed after the user equipment is replaced. Wherein the user key can be modified by the super key.
As an important verification index, the verification serial number needs to be generated in a manner of confidentiality and difficult to break, as shown in fig. 4, the generation manner of the verification serial number in this embodiment is as follows:
step S1201, generating plaintext information in advance;
and step S1202, generating a group of random numbers after encrypting the plaintext information. The plaintext information is encrypted by the super key, and the encryption algorithm may be preset, for example, a specific symmetric encryption algorithm.
Step S1203, using the random number as an index to extract data of the encrypted plaintext information, and generating a verification serial number. The generation of the verification serial number may be implemented in the server or in the battery management device. The encrypted plaintext information data is extracted by using the random number as an index to generate the verification serial number, and the verification serial number may be partial data obtained by extracting the plaintext information or all data obtained by extracting the plaintext information.
Referring to fig. 2, the specific verification method in step S140 of this embodiment is:
step S1401, receiving feedback key information and a feedback verification serial number sent by the user equipment. When the battery is connected with the user equipment, the user equipment sends an authentication invitation to the battery, and when the battery receives the authentication invitation sent by the user equipment, the battery sends response authentication information. In this embodiment, the response authentication information includes key information and authentication serial number information, and the user equipment sends feedback key information and feedback authentication serial number to the battery according to the key information and the authentication serial number information sent by the battery.
Step S1402 decrypts the received feedback key information and feedback sequence number. Decryption here may use the same algorithm as encryption described above, for example, both use a specific symmetric decryption algorithm.
Step S1403, comparing whether the received feedback key information is the same as the pre-stored key information;
step S1404, if yes, comparing whether the received feedback serial number is the same as the sent verification serial number;
if not, go to step S1406;
step S1405, if the received feedback serial number is the same as the sent verification serial number, the ue and the battery pass verification, otherwise, step S1406 is performed;
and step S1406, the user equipment and the battery are not verified.
In the prior art, personal information can be leaked in a plurality of ways, particularly, battery management equipment is better intelligent, so that a user key of a battery and use data of the personal battery stored in the battery are likely to cause leakage, great potential safety hazard can be brought to a user, the risk of battery embezzlement is increased in the use of the battery, a plurality of lawbreakers can acquire the user key and an authentication serial number of the battery through some illegal means, so that the possibility of battery embezzlement is greatly increased, the battery management equipment sets an authentication time limit, the feedback authentication information sent by the user equipment is the same as response authentication information sent by the battery management equipment in the authentication time limit, and the feedback key information sent by the user equipment and the key information stored by the battery management equipment are the same as the legal condition, and the response authentication information sent by the battery management equipment has authentication timeliness, the verification aging time is set by the battery management equipment, so that even if a thief knows a user key and a correct verification serial number, the battery cannot be normally used if the identity verification is not carried out within the verification aging time, and the further protection of the battery is realized.
After the battery starts to be charged formally, the battery management device periodically verifies whether the feedback key information and the feedback verification information are legal, as shown in fig. 3, specifically including:
in step S1701, the cycle time t is set to 5 min. That is, the battery will resend the response authentication information to the user equipment every 5min for authentication. The verification cycle time can be selected according to the power consumption condition. The set period time is shorter, the power consumption of the anti-theft alarm is higher, but the anti-theft effect is better.
Step 1702, when the battery formal discharge starts, recording the authentication success state of the user equipment. When the user equipment is verified to be in a legal condition, the battery management equipment or the background server records the authentication success state of the user equipment. For example, a user key and a verification serial number used when the user equipment is authenticated with the battery may be recorded accordingly.
Step S1703, identity authentication timing information of the user equipment is cleared, and timing is restarted until the verification period time is reached. And clearing the information of the user equipment and the battery during the authentication, and starting timing from the formal discharge of the battery. For example, the user equipment is re-authenticated within 5 minutes from the start of the regular discharge.
And S1704, clearing the identity authentication success state and retransmitting the response verification information. The user equipment authentication success status may be cleared, for example, the user key and the verification serial number used when the user equipment is authenticated with the battery, which are stored in the battery management device or the server, may be cleared.
Step S1705, verifying whether the received feedback key information and feedback verification information are legal or not;
step 1706, if the battery is legal, controlling the battery to continue to formally discharge the user equipment;
in step S1707, if the battery is not legitimate, the battery is controlled to stop discharging.
In the invention, the identity authentication is carried out through the combination of the user key and the authentication serial number, the battery is authenticated only under the condition that the combination of the user key and the authentication serial number is legal, and the battery starts to discharge formally after the authentication is successful, but in order to further ensure the battery, the periodic authentication process is added in the authentication mode of the invention, so that only a truly legal user can obtain the user key and the continuously changed authentication serial number simultaneously, even if the user key and the initially authenticated serial number are embezzled, the battery is only used for completing the discharge within a period of time, and the battery cannot be used continuously in the follow-up process, thereby improving the use safety of the battery, preventing other people from embezzleing the battery, and reducing the property loss; the legal condition described in this embodiment is a condition that a user key input by a user is the same as a user key stored in the battery management device, and an input authentication serial number is the same as a serial number generated by the battery management system.
In order to prevent the user key from being repeated, the user key is generated by the server by default, the generation mode is associated with the user registration account, and the server generates the user password according to the user ID to ensure the uniqueness of the user key due to different registration IDs used by different users; however, due to different battery usage occasions, the user password also supports user setting in consideration of user experience problems, for example, in a personal rental usage scenario, the user can be supported to set the user password, and the anti-theft performance is improved.
The battery management equipment controls the battery to provide the discharging current for the user equipment during pre-discharging to be smaller than the discharging current provided by the battery management equipment for the user equipment during formal discharging, because the user equipment usually has no standby battery, the user equipment is in a shutdown state after the electric energy of the user equipment is exhausted, the battery is in a shutdown discharging state by default under the normal condition, the battery management equipment cannot detect the connection state of the battery and the user equipment under the condition that the user equipment has insufficient electric energy and can be started, and at the moment, the battery management equipment or a battery management system cannot be triggered to be started, so that the battery performs low-current pre-discharging on the user equipment under the condition that the identity is not authenticated, the user can be connected with the battery in a communicating and electrically connected mode under the condition that a standby power supply does not exist, and the.
In the pre-discharging process, in order to establish electrical connection and communication between the user equipment and the battery, the battery is pre-discharged to enable the user equipment to operate, and the battery and the user equipment perform identity authentication within the pre-discharging time. For example, the battery management device presets a pre-discharge time of 1min, so that the pre-discharge time of the battery is 1min, and if the authentication cannot be successfully performed in the battery and the user equipment within 1min, the pre-discharge is finished.
In order to leave a buffering time for the discharging device, the battery management device of this embodiment sets a pre-discharge delay time 2s in advance, when the battery management device controls the battery to formally discharge the user device, the battery management device 100 starts the pre-discharge delay time 2s, and when the pre-discharge delay time 2s is reached, the pre-discharge process is ended.
