[0059] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0060] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0061] The main solution of the embodiment of the present application is: receiving the tag code of the initial battery returned by the RFID tag based on the read signal, wherein the tag code includes a tag verification code, and the read signal is used to read the RFID tag; when the tag code is received, the first compartment door of the power swap cabinet is opened to allow the user to place the initial battery into the first compartment door; if the initial battery is detected in the first compartment door, the battery information of the initial battery is obtained, and the RFID tag is verified based on the battery information and the tag verification code to obtain a verification result; if the verification result is that the tag verification is qualified, the second compartment door of the power swap cabinet is opened to determine the target battery in the second compartment door, so that the user can replace the initial battery based on the target battery to complete the battery replacement.

[0062] In the related art, in the related art, RFID coding adopts a static coding method, that is, once the code is written, it will no longer change. This coding method is simple, but the static RFID coding has no coding segment for coding verification, and the RFID tag of the battery is easily forged, resulting in reduced security of battery management.

[0063] The present application obtains the label code of the RFID tag based on the reading signal, wherein the label code includes the label verification code, thereby avoiding the problem that the static RFID code has no coding segment for coding verification. After receiving the label code, the initial battery is placed in the first compartment door opened by the battery swap cabinet, and then the battery information of the initial battery is obtained. The RFID tag is verified through the label code and the battery information, thereby avoiding the problem that the RFID tag of the battery is easily forged, resulting in reduced safety of battery management. After the verification, if the verification result is qualified, the second compartment door of the battery swap cabinet is opened to determine the target battery, so that the user can replace the initial battery based on the target battery to complete the battery replacement.

[0064] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, etc. The following takes a battery management device as an example to illustrate this embodiment and the following embodiments.

[0065] Based on this, the present application embodiment provides a battery management method based on RFID tags, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the battery management method based on RFID tags of the present application.

[0066] In this embodiment, refer to Figure 2 , Figure 2This is the architecture diagram of the battery management system based on RFID tags in this application. The battery management method based on RFID tags includes steps S100 to S400:

[0067] Step S100, receiving a tag code of an initial battery returned by an RFID tag based on a read signal, wherein the tag code includes a tag verification code, and the read signal is used to read the RFID tag;

[0068] It should be noted that the executor of this embodiment is a battery management device, which is provided with a battery swap cabinet. The battery swap cabinet is provided with a cabinet control system. The cabinet control system includes an RFID device, which is used to read the RFID tag code of the battery.

[0069] It is understandable that within the reading range of the RFID device of the battery management device, the RFID device continues to send a read signal within the reading range. If the RFID tag of the battery is within the reading range of the RFID device, the RFID device will read the information of the RFID tag of the battery and obtain the tag code of the RFID tag. The RFID tag information includes a check code and a preset check algorithm. Please refer to Figure 3 , Figure 3 This is a diagram of the RFID coding composition.

[0070] In a feasible implementation manner, the following steps are included before step S100:

[0071] Acquire initial battery information and acquire a first RFID tag;

[0072] It is understandable that the battery includes a battery management module. The first RFID tag is the initial RFID tag of the battery. The initial battery information includes the battery production date productDate, the battery serial number SN, the number of cycles, the health and the user number UID. The production line engineer enters the battery production date in the battery management device. In particular, the production date can also be read from the battery with the production date written. The battery management device reads the battery SN: batterySN from the battery management module of the battery and obtains the unfilled RFID tag on the battery.

[0073] Writing the initial battery information into the first RFID tag to obtain a second RFID tag;

[0074] It should be noted that the second RFID tag is an RFID tag after the initial battery information is written in. The battery management device writes the acquired initial battery information into the first RFID tag to obtain the second RFID tag.

[0075] Based on the initial battery information, the second RFID tag is coded and verified to obtain an RFID tag.

[0076] It is understandable that the RFID tag is a verified tag. The battery management device verifies the RFID tag written with the battery information based on the acquired battery information to obtain an RFID tag without writing errors.

[0077] For details, please refer to Figure 4 , Figure 4 Provides a production write flow chart, Figure 4 The steps are as follows:

[0078] 1a: The production line engineer enters the battery production date productDate on the cabinet control system or production tool used for production, and stores the battery production date in the battery information management module;

[0079] 1b: The cabinet control system or production tool reads the battery SN from the battery information management module: batterySN;

[0080] 2a: The RFID device of the cabinet control system scans the RFID tag of the battery that can be read currently;

[0081] 2b: The RFID device writes the batterySN, productDate, number of cycles (0), health (100), UID all F, calculated checksum R, and used check algorithm A into the RFID tag user area;

[0082] 2c: The RFID device reads the user area content from the RFID tag for verification;

[0083] 2d: The cabinet control system or production tool prompts the RFID tag to write the result through the interface or voice prompt.

[0084] In a feasible implementation manner, the step of writing the battery information into the first RFID tag to obtain the second RFID tag includes the following steps:

[0085] Encoding the initial battery information according to a preset encoding rule to obtain an information code, wherein the information code is used to represent the user area content of the RFID tag;

[0086] It should be noted that the information is encoded as the first 29 characters of the RFID, and the RFID is generally composed of 32 characters, such as Figure 3As shown in the figure, we can divide the 32-bit character code into three parts, namely information code, check code and check algorithm. The battery management device encodes the battery information in the user area of ​​the RFID tag to obtain the information code, where the RFID user area includes: battery SN, battery production date, battery cycle life, battery health and user ID.

[0087] The battery SN is used to record the battery to which the RFID tag belongs. On other devices that can read the internal data of the battery, it can be used to check whether the RFID tag is pasted incorrectly or has been stolen.

[0088] The battery production date is used to record the battery production date to avoid overuse of the battery. It is used to meet the needs of battery recycling management and to prevent batteries that should have entered the recycling cycle from being lost in the market and causing safety accidents.

[0089] The battery cycle life is used to record the number of times the battery is currently used, to meet the needs of battery recycling management, and to prevent batteries that should have entered the recycling cycle from being lost in the market and causing safety accidents.

[0090] Battery health users record the battery's SOH at the time to meet battery recycling management needs and prevent batteries that should have entered the recycling cycle from being lost in the market and causing safety accidents.

[0091] The user ID is used to record the identity information of the user currently using the battery, and is used to remind the user to park in compliance or drive away from the dangerous area when the battery is parked in a prohibited parking area or a dangerous area or a serious accident occurs in the parking area.

[0092] Obtaining a preset verification algorithm, and encoding the preset verification algorithm according to a preset encoding rule to obtain an algorithm code;

[0093] It is understandable that the verification algorithm is a verification algorithm for obtaining a verification code, and common verification algorithms include CRC8, CRC16 / CCITT(), CRC32 / and checksum, etc. The battery management device obtains a preset verification algorithm, and encodes the algorithm to obtain an algorithm code.

[0094] Based on the preset verification algorithm, the information code is calculated to obtain a tag verification code;

[0095] It should be noted that the check code is a byte converted to the corresponding hexadecimal character in the result obtained by the check algorithm. If the result of the CRC calculation is 0xF3, then C1 is 0x46 (ASCII code of character F) and C2 is 0x33 (ASCII code of character 3). The battery management device calculates the information encoding obtained through the preset check algorithm to obtain the tag check code.

[0096] Determine a label code based on the information code, the label check code and the algorithm code;

[0097] It is understandable that the battery management device combines the information code, check code and algorithm code to obtain the RFID tag information. Please refer to Figure 5 , Figure 5 Provides a detailed diagram of the composition of RFID coding.

[0098] in, Figure 5 R1~R4 are the results of the verification algorithm. The two bytes are converted to the corresponding hexadecimal characters. In the specific implementation, if the result of CRC16 calculation is 0xA8F3, then R1 is 0x41 (ASCII code of character A), R2 is 0x38 (ASCII code of character 8), R3 is 0x46 (ASCII code of character F), and R4 is 0x33 (ASCII code of character 3).

[0099] Figure 5 A1 is the check algorithm, which is the check algorithm for obtaining the check code. Common check algorithms include CRC16 / CCITT(), CRC32 / and checksum, etc.

[0100] In particular, to save storage space and improve the reading speed of the user data area, the battery SN can be calculated by using a checksum calculation method, such as using a CRC16 algorithm, which only requires two bytes to store the CRC16 calculation value of the battery SN.

[0101] In particular, in order to save storage space and improve the reading speed of the user data area, the user ID can be stored in hexadecimal format, so the storage space for an 11-digit phone number only requires 5 bytes.

[0102] The tag code is written into the first RFID tag to obtain a second RFID tag.

[0103] It should be noted that the second RFID tag is a tag after the code is written in. The battery management device writes the obtained tag code into the first RFID tag to obtain the second RFID tag.

[0104] In a feasible implementation manner, the initial battery information is encoded according to a preset encoding rule, and the step of obtaining the information encoding includes the following steps:

[0105] Encoding the battery serial number in the battery information according to a preset encoding rule to obtain a serial code;

[0106] It should be noted that the battery management device encodes the battery serial number, such as Figure 5As shown in B1~B20 in , the sequence code is obtained.

[0107] Encoding the battery production date in the battery information according to a preset encoding rule to obtain a date code;

[0108] It is understood that the battery management device encodes the battery production date, e.g. Figure 5 The Y1M1D1 shown is the year, month and day of battery production. The year records the tens and units digits of the year, such as 0x18 for 2024, and the month and day record the month and day, such as March 12, M1 is 0x03, D1 is 0x0C, and the date code is obtained.

[0109] Encoding the battery cycle number in the battery information according to a preset encoding rule to obtain a cycle code;

[0110] It should be noted that the battery management device encodes the number of battery cycles, for example Figure 5 The C1C2 shown records the current cycle number of the battery, and its value is (C1<<8)|C2, thereby obtaining the cycle code.

[0111] Encoding the battery health value in the battery information according to a preset encoding rule to obtain a health value code;

[0112] It is understood that the battery management device encodes the battery health value, for example, Figure 5 The S1 shown records the battery health, whose value is >0 and less than 100, and then obtains the health value code, wherein the battery health value is obtained by detecting the health value detection model preset in the battery management device. The battery management device monitors the key factors affecting the battery health value in real time through the sensors in the battery swap cabinet, and inputs the detected data into the preset health value detection model to obtain the battery health value.

[0113] Get the preset user code;

[0114] It should be noted that the battery management device obtains an initial user code, for example, U1~U11 records the user ID, typically the characters of the user's phone number, and then obtains a preset user code, wherein the initial user code is set to all Fs.

[0115] An information code is determined based on the sequence code, the date code, the cycle code, the health value code and the user code.

[0116] It is understandable that the battery management device converts the sequence code, sequence code, cycle code, health value code and user code into Figure 5 The positional relationship in is combined to obtain the information encoding.

[0117] Step S200, when the label code is received, the first door of the battery swap cabinet is opened to allow the user to place the initial battery into the first door;

[0118] It should be noted that the RFID device also includes a warehouse control device, which is used to control the opening and closing of the warehouse door. The first warehouse door is an idle warehouse door. After the RFID device of the battery management device reads the RFID tag of the battery, the battery management device will select an idle battery warehouse and open the warehouse door, and prompt the user to put the initial battery for battery replacement into the first warehouse door.

[0119] Step S300, if it is detected that the first compartment door has the initial battery, then obtaining the battery information of the initial battery, and performing tag verification on the RFID tag based on the battery information and the tag verification code to obtain a verification result;

[0120] It is understandable that the verification result is the result of judging the legitimacy of the tag to avoid security risks caused by the misappropriation and forgery of the tag. When the battery swap cabinet of the battery management equipment detects that a battery swap battery has been returned, the battery swap cabinet can directly obtain the battery information stored in the battery information management module of the battery, and perform tag verification on the battery information and the verification code in the RFID tag code to obtain the verification result.

[0121] In a feasible implementation manner, step S300 includes the following steps:

[0122] If it is detected that the battery exists in the first compartment door, obtaining battery information;

[0123] It should be noted that the battery information includes the battery SN, production date, and usage status of the battery, among which the battery includes a battery information management module and an RFID tag, and the battery information is obtained from the battery information management module. After the battery is placed in the first compartment door of the battery swap cabinet of the battery management equipment, the battery is physically connected to the battery swap cabinet, and the battery swap cabinet can directly obtain the battery information stored in the battery information management module of the battery.

[0124] The battery code is calculated by a preset verification algorithm to obtain a battery verification code;

[0125] It should be noted that the battery management device performs algorithm calculation on the obtained battery information according to a preset verification algorithm to obtain a battery verification code.

[0126] The tag verification code and the battery verification code are coded and verified to obtain a verification result.

[0127] It is understandable that the battery management device will compare the tag verification codes of the battery and the RFID tag for tag legitimacy, and obtain a verification result of the tag legitimacy of the RFID tag used to characterize the written information, thereby preventing the use of tampered or counterfeit batteries and ensuring battery replacement safety and battery quality.

[0128] Step S400: If the verification result is that the tag verification is qualified, the second compartment door of the battery exchange cabinet is opened, and the target battery in the second compartment door is determined so that the user can replace the initial battery based on the target battery to complete the battery replacement.

[0129] It is understandable that the battery management device analyzes the verification results. If the inspection is qualified, the battery management device will select a suitable battery as the target battery and open the second compartment door corresponding to the target battery. The battery management device involves evaluating various battery indicators in the process of selecting a battery, such as remaining power, life and health status, to ensure that the best option is provided to the user.

[0130] In this embodiment, a verification segment is added to the RFID code of the battery management device to verify whether the code is a legitimate battery RFID tag, thereby improving the security of battery management, and defining data items in the RFID tag user area to meet the needs of traffic management, fire management, battery replacement management, etc.

[0131] The present application embodiment provides a battery management method based on RFID tags, referring to Figure 6 , Figure 6 This is a flow chart of the second embodiment of the battery management method based on RFID tags of the present application.

[0132] In a feasible implementation manner, the following steps are included after step S400:

[0133] Step S10, if it is detected that the second compartment door is opened, obtaining target battery information of the target battery;

[0134] It should be noted that the target battery information is the battery information stored in the battery management module of the battery. After the battery management device opens the door of the battery for battery replacement, the battery replacement will obtain the battery information stored in the battery management module of the target battery.

[0135] Step S20, if it is detected that the target battery is taken out, modifying the first target RFID tag of the target battery based on the target battery information to obtain a second target RFID tag;

[0136] It is understandable that when the battery management device detects that the battery has been taken out, because the battery data will be updated, the label code corresponding to the battery needs to be updated synchronously. The battery management module of the battery management device notifies the RFID device to update the battery label content, and then the RFID device of the battery management device scans the RFID tag code of the target battery and reads the RFID user area content. If the scan times out, the battery information management module synchronizes the RFID tag user area update result to the cloud platform and displays the reason for failure: Failed to update the RFID tag user area data due to failure to scan the RFID tag.

[0137] Step S30, verifying the battery serial number in the target battery information with the battery serial number of the second target RFID tag to obtain a target verification result;

[0138] It should be noted that the RFID device of the battery management device checks whether the battery serial numbers in the RFID tag and the battery information are consistent to obtain the target verification result. If they are inconsistent, the battery information management module synchronizes the RFID tag user area update result to the cloud platform and displays the reason for failure: Failed to update the RFID tag user area data due to battery SN error.

[0139] Step S40: determining a target RFID tag based on the target verification result and the second target RFID tag.

[0140] It is understandable that after the battery management device obtains consistent verification results, the RFID device of the battery management device writes the calculated user area data into the RFID user area, obtains the target RFID tag, and verifies the written information. If the verification fails, the reason is analyzed. If the device fails to read the RFID user area data, the battery management module is notified to check the RFID tag user area data failure, and the reason is the RFID user area reading failure. If the device fails to check the RFID user area data, the battery management module is notified to check the RFID tag user area data writing failure, and the reason is the RFID user area write error.

[0141] For details, please refer to Figure 7 , Figure 7 Provides an updated flow chart of the battery replacement process. Figure 7 The specific steps are as follows:

[0142] 1a: Get the user ID information UID of the user who removed the battery;

[0143] 1b: Get the RFID tag code RFIDSN corresponding to the battery;

[0144] 1c: Obtain the battery SN, battery cycle number CycleNum, and battery health SOH from the battery management information module of the battery;

[0145] 2a: When it is detected that the battery has been removed, the battery management module notifies the RFID device to update the battery tag content, carrying parameters including RFIDSN, SN, CycleNum, SOH, etc.;

[0146] 2b: The RFID module scans the RFID tag code as the RFIDSN tag and reads the RFID user area content. If the scan times out, jump to 2e to notify the battery management module that the update of the RFID tag user area data failed because the scanning of the RFID tag failed;

[0147] 2c: The RFID device checks whether the batterySN of the RFID tag is consistent.
