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 embodiment provides a battery anti-theft method, wherein the battery controls discharge through a battery management device, and the battery is physically connected or disconnected with a consumer through a contact, an interface structure or other contact structures to establish a power supply path or open a circuit. The battery management equipment is connected with the server through a wireless communication network, is positioned at the battery side and controls the power supply path or the open circuit through a preset instruction and a physical structure.
The electric device described in this embodiment is a device that receives power from a battery to implement its corresponding function, for example, a device that converts electric energy into kinetic energy such as an electric bicycle, an electric automobile, or a device that relies on electric energy as energy such as a mobile phone or a computer. In this embodiment, the electric device is a vehicle terminal, and the terminal device, which is disposed on the vehicle for controlling the vehicle and communicating with the server or the mobile terminal, includes but is not limited to an antenna box.
Since the battery management device of the present embodiment is located on the battery side, the battery management device and the server establish a connection through a wireless network, and in order to adapt to different ranges of communication, the battery management device in the present application establishes a communication connection with the server through the 2/3/4/5G communication module. The battery anti-theft method is implemented by a battery management device, as shown in fig. 1, and includes:
step S110, the battery status information is sent to a server through a wireless communication network. The battery state information includes battery position information and battery fault information. In the battery anti-theft management, especially in the sharing field, the battery state is very important to grasp, so the battery state information of the embodiment is collected and sorted by the battery management device and uploaded to the server in real time, the battery position information and the battery fault information in the battery state are two important references in the battery anti-theft, the position of the battery and the fault state of the battery are known in real time, especially the disassembly fault state of the battery, and the battery anti-theft early warning, the loss recovery and the like are all important functions.
And step S120, pre-discharging the battery when the battery is detected to be connected with the electric equipment. In the present embodiment, whether the battery is connected to the electric device may be detected by detecting a voltage change at the battery terminal or by a sensor. For example, when the voltage of the battery becomes instantaneously high, it indicates that the battery is connected to the electric device.
As described above, if authentication is required, the system of the electric device needs to be activated, but in practical applications, the battery of the electric device is often exhausted or the electric quantity is extremely low, so that the system is in an off state, and subsequent authentication cannot be performed. Namely, when the electric equipment is detected to be connected with the battery, the battery can unconditionally charge the battery for one minute under low current, so that the principle of non-authentication and non-discharge is not hindered, and the communication and identity verification of the user with the battery can be ensured under the condition of no power supply.
And step S130, performing identity authentication on the electric equipment to obtain an authentication result. The battery management device may perform various methods for authenticating the electric device, for example, an electric protocol may be set in the battery, and when the electric device conforms to the electric protocol, the electric device may be considered to be authenticated, that is, the authentication is passed. In other embodiments, the ID number of the battery may also be sent to the electric device, and when the electric device is connected to the battery, if it is detected that the battery ID number stored in the electric device matches the ID number of the battery, the verification is passed. Similarly, the device number of the electric device may be stored in the battery management device in advance, and when the electric device is connected to the battery and the battery management system can recognize the device number of the electric device, the verification is passed. Wherein, the verification is passed, that is, the verification result is correct.
And step S140, when the verification result is correct, the battery is formally discharged. That is, when the verification of the electric equipment is passed, the battery management equipment enables the battery to start the formal discharging mode.
The discharge current of the formal discharge process of the battery is larger than that of the pre-discharge process, and the purpose is to realize the quick charge of the electric equipment under the safe condition. When the verification of the electric equipment is passed, namely, the verification result is correct, the battery management equipment enables the battery to start formal discharging.
And step S150, when the verification result is incorrect, the battery management device controls the battery to stop discharging after the pre-discharging is finished. If the verification result is incorrect, the user equipment identity is not legal, and the battery stops discharging at the moment.
In this embodiment, a flow of the method for authenticating the identity of the electric device in step S130 is shown in fig. 2, and includes:
step S1301, storing user key information of the battery. The user key is a character string with fixed length, contains letters and numbers and can be used for identifying the battery identity.
And step S1302, triggering the electric equipment to send a verification serial number to the electric equipment according to the request of the electric equipment. And after the battery is connected with the user equipment, the user equipment sends a verification invitation to the battery, and after the battery receives the verification invitation sent by the user equipment, the battery sends a verification serial number to the electric equipment. The verification serial number may be randomly generated by the battery management device according to a certain encoding rule.
In order to prevent capturing plaintext information of a single user, the battery management device generates a new serial number each time a user of the power utilization device reads data in the battery management device, and the generated serial numbers are different each time.
In the practical application process, some electric devices can independently complete identity verification, such as a mobile phone, a computer, a power-assisted vehicle system and the like, some electric devices can complete the identity verification process by means of intelligent devices such as the mobile phone and the like, for example, the mobile phone is connected with the electric devices through the existing application program, and in the verification process, the mobile phone receives user key information and plaintext information sent by battery management equipment and then transmits data to the battery management equipment.
As shown in fig. 3, the verification serial number generation manner described in step S1302 is as follows:
step 13021, generating plaintext information in advance;
step S13022 generates a set 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 S13023 is to extract the encrypted plaintext information data using the random number as an index to generate 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, which may be partial data of the extracted plaintext information or all data of the extracted plaintext information.
Step S1303, receiving a feedback serial number and feedback user key information sent by the electric equipment;
in step S1304, the received feedback sequence number and feedback key information are decrypted. Decryption here may use the same algorithm as encryption described above, for example, both use a specific symmetric decryption algorithm.
Step S1305, comparing whether the received feedback key information is the same as the pre-stored key information;
step 1306, if yes, comparing whether the received feedback sequence number is the same as the sent verification sequence number; if not, go to step S1308;
step 1307, if the received feedback serial number is the same as the sent verification serial number, the user equipment and the battery verification result are correct;
in step S1308, the ue and the battery verification result are incorrect.
The battery management device of the embodiment acquires the battery position information through a GPS positioning module and/or a near field communication hotspot which are installed on the battery, wherein the near field communication hotspot comprises a Bluetooth module and an NFC communication module.
The battery fault information of the embodiment includes battery disassembly fault information, and when the battery is disassembled, the battery management device detects the battery disassembly fault according to the battery disassembly fault information, and forces the battery to stop discharging.
In the process of using the battery, it is highly likely that the battery user key or the verification serial number leaks out, which causes the battery to be stolen and used as other purposes, so that in the process of formal discharging of the battery, the battery anti-theft method includes a process of periodic verification of the battery, and a specific flow is shown in fig. 4, and specifically includes:
step S1601, setting the verification period time t to 5 min. That is, the battery will resend the response authentication information to the user equipment every 5min for authentication.
The setting of the cycle time can be adjusted according to different use environments, the use environments comprise common electric equipment, an electric field and the like, the cycle time is set to be 5min by combining the real-time performance of load and illegal identity check, and the cycle is also used as the communication heartbeat of the user equipment and the battery. The verification cycle time can be selected according to the power consumption requirement. The set period time is shorter, the power consumption of the anti-theft alarm is higher, but the anti-theft effect is better.
Step S1602, when the battery formal discharge starts, the authentication success status of the user equipment is recorded. And after the user equipment is successfully authenticated, 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 S1603, the 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.
Step S1604, clearing the status of successful authentication, and performing authentication again, if the authentication result is correct, performing step S1605, otherwise performing step S1606, where the authentication process in this step is the same as the authentication process in step S130, and is not described herein again.
In the periodic verification process, plaintext information sent by the battery management equipment every time is different;
step 1605, making the battery continue the formal discharging process;
in step S1606, the battery is discharged after the verification cycle time is completed.
