[0044] 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.

[0045] 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.

[0046] The main solution of the embodiment of the present application is: receiving a data processing instruction for a target battery parameter; based on the data processing instruction, determining a target parameter block from a binary file; wherein the binary file includes a plurality of parameter blocks of fixed length, the tail of each parameter block is a reserved area, and the parameter block is configured to store data using a preset structure format; based on the address information of the target parameter block, executing a data processing action corresponding to the data processing instruction on the target parameter block to obtain a processing result.

[0047] In this embodiment, for the convenience of description, the following description is made with the controller as the execution subject.

[0048] At present, with the continuous increase in voltage levels, BMS (Battery Management System) mainly uses parameter management methods such as EEPROM, configuration files, and databases to manage hundreds or thousands of battery parameters.

[0049] However, when using parameter management methods such as EEPROM, configuration files, and databases to manage battery parameters, the following problems exist:

[0050] 1. When using EEPROM as storage, additional EEPROM chips and communication interfaces are required, which not only has high hardware costs but also slow reading and writing speeds;

[0051] 2. When using the configuration file, the BMS software needs to handle the complex correspondence between parameter characters, and the parameters cannot be modified directly and conveniently, and a copy needs to be used, etc., which makes the software implementation more complicated;

[0052] 3. When using the database, if there are many battery parameters, the software needs to process more complex SQL statements. At the same time, when adding battery parameters, the data table in the database needs to be rebuilt, resulting in the loss of stored battery parameters, and poor scalability and ease of use.

[0053] Therefore, when the battery parameters are managed using the above parameter management method, the management process is relatively complicated.

[0054] The present application provides a solution. Compared with the parameter management method of using EEPROM, configuration files, databases, etc. in the related art to manage battery parameters, the present application uses a preset structure format to store battery parameters in parameter blocks when managing battery parameters, ensuring that the data layout of each parameter block is known. At the same time, the battery parameters are structured, and binary can be used for direct reading and writing, making the reading and processing operations of battery parameters more efficient, reducing the overhead of the program to judge and convert the data format at runtime, and improving the efficiency of reading and writing battery parameters. At the same time, the parameter blocks are dispersed in the binary file, and a reserved area is reserved in the tail area of ​​the parameter block to ensure the independence of the parameter block, so that on the basis of ensuring stability and reliability, the reserved area provides scalability for the subsequent expansion of the reference block, that is, when new battery parameters need to be added later, the new battery parameters can be written into the reserved area without redesigning the entire data structure, while reducing the maintenance cost and complexity, it also improves the scalability of the parameters, thereby simplifying the management process of battery parameters.

[0055] It should be noted that the execution subject of this embodiment may be an electronic device, a controller, etc. capable of realizing the above functions. The controller is taken as an example to illustrate this embodiment and the following embodiments.

[0056] Based on this, the present application embodiment provides a battery parameter management method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the battery parameter management method of the present application.

[0057] In this embodiment, the battery parameter management method includes steps S10 to S30:

[0058] Step S10, receiving a data processing instruction for a target battery parameter.

[0059] Step S20: determining a target parameter block from the binary file based on the data processing instruction.

[0060] The binary file includes a plurality of parameter blocks of fixed length, the tail of each parameter block is a reserved area, and the parameter block is configured to store data using a preset structure format.

[0061] In this embodiment, the data processing instructions may be data storage instructions, or data reading instructions, etc., and the parameter block configuration may use a preset structure format and a one-byte alignment to store data, so as to improve the efficiency of battery parameter access and the security of processing.

[0062] Specifically, the user may input the data processing instruction by interacting with the user interface of the controller. After receiving the data processing instruction, in order to quickly determine the target parameter block from the binary file, the controller further, as an optional implementation, specifically includes:

[0063] Step S201A: if the data processing instruction is a data read instruction, then determine the target identification information of the target parameter block.

[0064] Step S202A, searching for a mapping relationship, and determining the target address information corresponding to the target identification information.

[0065] The mapping relationship includes the corresponding relationship between the identification information and the address information.

[0066] Step S203A: read the target parameter block from the binary file based on the target address information.

[0067] In this embodiment, the target address information may be a file offset address, that is, a position identifier of the target parameter block in the binary file, which is used to indicate the distance of the target parameter block relative to the beginning of the binary file.

[0068] It should be noted that with the continuous increase in voltage levels, the number of batteries managed by BMS has reached hundreds and thousands, and accordingly, the battery parameters managed by BMS have also increased sharply, from the original dozens of battery parameters to hundreds of parameters. In order to better manage a large number of battery parameters, the correspondence between parameter blocks and battery parameters and batteries can be pre-set, that is, the parameter blocks are used to store which battery parameters of which batteries, such as parameter block 1 is used to store the current parameters, voltage parameters, temperature parameters, capacity parameters, etc. of battery A and battery B, and parameter block 2 is used to store the internal resistance parameters, charging time parameters, operating voltage range parameters, etc. of battery A and battery B. After setting the battery parameters of which batteries the parameter blocks are used to store, an identification information can be assigned to each parameter block, and the identification information can be bound to the address information, so that the corresponding parameter block can be quickly read from the binary file according to the identification information, or the battery parameters can be written into the corresponding parameter block.

[0069] Specifically, when the data processing instruction is a data reading instruction, the battery information corresponding to the target battery parameter can be determined, and the target identification information of the target parameter block storing the target battery parameter, that is, the ID information of the target parameter block, can be determined based on the target battery parameter and the battery information. After the target identification information of the target parameter block is determined, the target address information corresponding to the target identification information can be determined based on the correspondence between the identification information and the address information, and the target parameter block can be read from the binary file based on the target address information.

[0070] In this embodiment, when reading the target parameter block from the binary file, the position of the target parameter block in the binary file can be quickly found through the target identification information of the target parameter block, and the required battery parameters can be directly accessed without having to read them one by one from the beginning of the file, thereby reducing unnecessary search and traversal time, thereby improving the processing efficiency of the battery parameters.

[0071] It should be noted that, in order to ensure the correctness of data and the stability of the system, and to avoid binary file corruption or format errors, which may cause more serious problems in subsequent processing, further, as an optional implementation, step S20 further specifically includes:

[0072] Step S201B, reading the current file configuration information of the binary file from the common parameter block of the binary file.

[0073] The public parameter block is the first parameter block of the binary file, and the current file configuration information includes file version number information and magic number information.

[0074] Step S202B, determining whether the current file configuration information is consistent with the preset file configuration information.

[0075] Step S203B: if the current file configuration information is consistent with the preset file configuration information, a target parameter block is determined from the binary file based on the data processing instruction.

[0076] Step S204B: if the current file configuration information is inconsistent with the preset file configuration information, all parameter blocks in the binary file are initialized.

[0077] In this embodiment, the magic number may be a special byte sequence used for file format identification, located at the beginning of the file, which can help the program identify the type and format of the file.

[0078] Specifically, refer to Figure 2 As shown, Figure 2 This is a schematic diagram of the overall layout of the binary file. Figure 2In order to ensure the stability and reliability of the parameter block, there is a space between any two adjacent parameter blocks stored in the binary file, that is, a reserved area. The first parameter block of the binary file is a public parameter block, that is, a shared parameter block, and the current version information of the binary file can be written into the public parameter block. When reading the target parameter block from the binary file, the current file configuration information of the binary file can be read from the public parameter block. After reading the current file configuration information of the binary file from the public parameter block of the binary file, it is determined whether the current file configuration information is consistent with the preset file configuration information, that is, whether the current file version information and the current magic number are consistent with the preset file version information and the preset magic number information. When the current file configuration information is consistent with the preset file configuration information, the target parameter block is determined from the binary file based on the data processing instruction. When the current file configuration information is inconsistent with the preset file configuration information, all parameter blocks in the binary file are initialized.

[0079] In this embodiment, by checking the consistency between the current file configuration information and the preset file configuration information, it can be ensured that the battery parameters processed subsequently are valid and can be correctly parsed. At the same time, when the current file configuration information is inconsistent with the preset file configuration information, the battery parameters in all parameter blocks are automatically restored to the default values, ensuring that the system can operate in a known and stable state and reducing the risk of failure.

[0080] Step S30, based on the address information of the target parameter block, executing the data processing action corresponding to the data processing instruction on the target parameter block to obtain a processing result.

[0081] Specifically, when executing the data processing action corresponding to the data processing instruction on the target parameter block, when the data processing instruction is a data reading instruction, the data processing action corresponding to the data processing instruction is to read the target parameter block from the binary file. When the data processing instruction is a data storage instruction, the data processing action corresponding to the data processing instruction is to write the target battery parameters into the target parameter block. When writing the target battery parameters into the target parameter block, in order to avoid disrupting the arrangement order of the battery parameters already existing in the target parameter block when writing the target battery parameters, further, as an optional implementation, step S30 specifically includes:

[0082] Step S301: if the data processing instruction is a data storage instruction, the target battery parameter is written into a reserved area of ​​the target parameter block.

[0083] The arrangement order of the battery parameters written into the target parameter block remains unchanged.

[0084] In this embodiment, in order to facilitate subsequent expansion of the parameter process, the initial value of the data in the reserved area may be set to 0.

[0085] When the data processing instruction is a data storage instruction, when writing the target battery parameters into the reserved area of ​​the target parameter block, in order to ensure the accuracy of the battery parameters stored in the target parameter block and avoid tampering, further, as an optional implementation, step S301 specifically includes:

[0086] Step S3011, based on the address information of the target parameter block, read the target cyclic redundancy check CRC code corresponding to the target parameter block and the byte information of the target parameter block.

[0087] The byte information includes the battery parameter byte information stored in the target parameter block and the byte information in the reserved area.

[0088] Step S3011, using the byte information to calculate the current cyclic redundancy check CRC code of the target parameter block.

[0089] Step S3012, determining whether the current cyclic redundancy check CRC code is consistent with the target cyclic redundancy check CRC code.

[0090] Step S3013, if the current cyclic redundancy check CRC code is consistent with the target cyclic redundancy check CRC code, the target battery parameters are written into the reserved area, and after the target battery parameters are written into the reserved area, the new byte information in the target parameter block is read, and the new current cyclic redundancy check CRC code of the target parameter block is calculated using the new byte information, and the new cyclic redundancy check CRC code is used as the target cyclic redundancy check CRC code.

[0091] Step S3014: If the current cyclic redundancy check CRC code is inconsistent with the target cyclic redundancy check CRC code, the target parameter block is initialized.

[0092] In this embodiment, the total length of the target parameter block and the reserved area can be pre-set, such as setting the total length of the target parameter block and the reserved area to 256 bytes. When the battery parameters are not written in the target parameter block and the reserved area, the initial values ​​of the data in the target parameter block and the reserved area are both 0.

[0093] Specifically, refer to Figure 3 As shown, Figure 3 is the positional relationship between the target parameter block and the target cyclic redundancy check CRC (CyclicRedundancy Check) code. Figure 3In the example, the target parameter block and the reserved area are used as areas for writing battery parameters. Assuming that the battery parameters written into the target parameter block for the first time are parameter 1 and parameter 2, the initial value of the target parameter block changes, but the initial value of the data in the reserved area is still 0. At this time, the byte information of the target parameter block after writing the battery parameters is combined with the byte information in the reserved area to calculate the cyclic redundancy check CRC code, and the cyclic redundancy check CRC code is written into the header position of the target parameter block as the target current cyclic redundancy check CRC code of the target parameter block, that is, the cyclic redundancy check CRC code is used as the fixed header of the target parameter block.

[0094] For example, after the target parameter block stores 10 bytes of battery parameters for the first time, the initial values ​​of the 10 bytes in the target parameter block change, that is, they are no longer 0, but the initial values ​​of the remaining 246 bytes are still 0. At this time, the 256 bytes are taken as a whole to calculate the cyclic redundancy check CRC code of the target parameter block after the battery parameters are stored for the first time, and the cyclic redundancy check CRC code is used as the target cyclic redundancy check CRC code. According to the address of the target parameter block in the binary file, the target cyclic redundancy check CRC code is written into the header position of the target parameter block.

[0095] After receiving the data storage instruction and determining the target parameter block according to the data storage instruction, the target cyclic redundancy check CRC code corresponding to the target parameter block and the byte information of the target parameter block can be read from the binary file according to the address information of the target parameter block.

[0096] After obtaining the byte information, the current cyclic redundancy check CRC code of the target parameter block can be calculated using the byte information. After calculating the current cyclic redundancy check CRC code of the target parameter block, it can be determined whether the current cyclic redundancy check CRC code is consistent with the target cyclic redundancy check CRC code. When the current cyclic redundancy check CRC code is consistent with the target cyclic redundancy check CRC code, it is determined that the battery parameters written into the target parameter block have not been tampered with, and the target battery parameters are written into the reserved area at this time. After the target battery parameters are written into the reserved area, the new byte information in the target parameter block can be read, and the new current cyclic redundancy check CRC code of the target parameter block can be calculated using the new byte information, and the new current cyclic redundancy check CRC code is used as the target cyclic redundancy check CRC code. When the current cyclic redundancy check CRC code is inconsistent with the target cyclic redundancy check CRC code, it is determined that the battery parameters stored in the target parameter block have been tampered with, and in order to ensure the correctness of the battery parameters, the target parameter block is initialized at this time to avoid the occurrence of erroneous analysis results when the battery parameters are subsequently used for analysis and processing.

[0097] It should be noted that when the target parameter block needs to write new battery parameters, the new battery parameters are written into the reserved area at the end of the target parameter block, as shown in FIG. Figure 4 As shown, Figure 4 The figure is a schematic diagram of the expansion of the target parameter block. The total bytes of the target parameter block and the reserved area are 256. Before writing the new battery parameters, the target parameter block and the reserved area have used 128 bytes. When the battery parameters are expanded from 128 bytes to 200 bytes, the expanded 72 bytes of new battery parameters are written into the reserved area, and the size of the reserved area is reduced, that is, the size of the reserved area is changed from 128 bytes to 56 bytes, and it will not affect the 128 bytes of battery parameters written previously. That is, after the battery parameters are expanded and the program is updated, the battery parameters previously saved in the target parameter block will not change, and only the new battery parameters written need to be reconfigured.

[0098] In addition, when writing new battery parameters, the application can update safely in the reserved area at the end of the target parameter block when the new battery parameters do not completely use up the target parameter block, without affecting the original battery parameters in the target parameter block. At the same time, since the parameter blocks are distributed in different areas in the binary file and the segmentation does not overlap, when the target parameter block is expanded, it will not affect other parameter blocks, thus meeting the high scalability requirements for battery parameters.

[0099] In this embodiment, when writing the target battery parameters into the target parameter block, the target cyclic redundancy check CRC code in the header of the target parameter block is used to check the current cyclic redundancy check CRC code of the target parameter block, which can ensure the correctness of the battery parameters stored in the target parameter block and prevent the battery parameters stored in the target parameter block from being tampered with. At the same time, when writing the target battery parameters into the target parameter block, the target battery parameters are written into the reserved area, that is, the reserved area is used as a buffer for subsequent parameter expansion. When the battery parameters in the target parameter block need to be expanded, as long as the length of the expanded battery parameters does not exceed the length of the reserved area, it will not affect the parameter blocks adjacent to the target parameter block, thereby ensuring the stability of the stored parameters and improving the extensibility of the target parameter block.

[0100] In this embodiment, compared with the related art, the battery parameters are managed by the parameter management method using EEPROM, configuration files, databases, etc. When managing the battery parameters, the battery parameters are stored in the parameter block using a preset structure format to ensure that the data layout of each parameter block is known. At the same time, the battery parameters are structured, and binary direct reading and writing can be used, making the reading and processing operations of the battery parameters more efficient, reducing the overhead of the program to judge and convert the data format during operation, and improving the efficiency of reading and writing battery parameters. At the same time, the parameter blocks are dispersed in the binary file, and a reserved area is reserved in the tail area of ​​the parameter block to ensure the independence of the parameter block, so that on the basis of ensuring stability and reliability, the reserved area provides scalability for the subsequent expansion of the reference block, that is, when new battery parameters need to be added later, the new battery parameters can be written into the reserved area without redesigning the entire data structure, while reducing the maintenance cost and complexity, and also improving the scalability of the parameters, thereby simplifying the management process of the battery parameters.

[0101] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the battery parameter management method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.

[0102] Specifically, to facilitate a better understanding of this embodiment, a specific example is provided below.

[0103] Reference Figure 5 As shown, Figure 5The flowchart for managing battery parameters using binary files is shown in FIG. 1 . When managing battery parameters, it is possible to predefine which parameters of which batteries are stored in each parameter block, and assign an identification information and an address in the binary file to each parameter block, and bind the identification information and the address so that the corresponding parameter block can be directly read from the binary file according to the identification information, or the battery parameters can be written into the corresponding parameter block. After assigning identification information to the parameter block, it is also necessary to determine whether there is a corresponding binary file in the file system. If there is no corresponding binary file, it is necessary to create the corresponding binary file and write the parameter block into the file according to the pre-allocation according to the registered default parameters, that is, determine the position of each parameter block in the binary file according to the address information of each parameter block in the binary file. If there is a corresponding binary file, check whether the public header magic number and the file version have changed, that is, read the current file configuration information of the binary file from the public parameter block of the binary file, and determine whether the current file configuration information is consistent with the preset file configuration information. When the current file configuration information is inconsistent with the preset file configuration information, the parameter block is written into the file according to the pre-allocation based on the registered default parameters; when the current file configuration information is consistent with the preset file configuration information, the battery parameters are initialized and the battery parameters are written to the corresponding location according to the address information of the parameter block, or the corresponding parameter block is read from the binary file according to the address information of the parameter block.

[0104] It is understandable that in order to prevent the battery parameters stored in the binary file from being tampered with and ensure the correctness of the battery parameters, a cyclic redundancy check CRC code can be used for verification when reading the parameter block or writing the battery parameters into the parameter block, that is, referring to Figure 6-Figure 7 As shown, Figure 6 The following is a flowchart of reading parameter blocks from a binary file. Figure 7 The figure is a flowchart for writing battery parameters into parameter blocks.

[0105] Reference Figure 6As shown, in the scenario of reading the target parameter block from the binary file, the ID of the target parameter block, that is, the target identification information of the target parameter block, is first determined, and the target address information corresponding to the target identification information of the target parameter block is determined according to the mapping relationship, and the target parameter block and the target cyclic redundancy check CRC code corresponding to the target parameter block are read from the binary file according to the target address information. After reading the target parameter block and the target cyclic redundancy check CRC code corresponding to the target parameter block, calculate whether the CRC16 of the application parameter area is consistent with the CRC16 stored in the header, that is, use the byte information of the target parameter block to calculate the current cyclic redundancy check CRC code of the target parameter block, and judge whether the current cyclic redundancy check CRC code is consistent with the target cyclic redundancy check CRC code. In the case where the current cyclic redundancy check CRC code and the target cyclic redundancy check CRC code are inconsistent, the reading fails at this time, that is, the battery parameters stored in the parameter block are tampered with, and the correct battery parameters cannot be read. At this time, the target parameter block is initialized and the battery parameters stored in the target parameter block are restored to the default parameters. When the current cyclic redundancy check CRC code is consistent with the target cyclic redundancy check CRC code, it is determined that the battery parameters in the parameter block have not been tampered with, and the correct battery parameters can be successfully read from the target parameter block.

[0106] Reference Figure 7As shown, for the scenario of writing the target battery parameters into the target parameter block, based on the above operation, after reading the target cyclic redundancy check CRC code corresponding to the target parameter block and the byte information of the target parameter block from the binary file, first use the byte information to calculate the current cyclic redundancy check CRC code of the target parameter block, and determine whether the current cyclic redundancy check CRC code is consistent with the target cyclic redundancy check CRC code. In the case where the current cyclic redundancy check CRC code is consistent with the target cyclic redundancy check CRC code, the target battery parameters are written into the reserved area at the end of the target parameter block. After the target battery parameters are written into the reserved area at the end of the target parameter block, the new byte information in the target parameter block can be read, and the new current cyclic redundancy check CRC code of the target parameter block can be calculated using the new byte information, and the new current cyclic redundancy check CRC code is used as the target cyclic redundancy check CRC code, that is, the fixed-length application parameter area CRC16 is calculated, and the fixed-length application parameter area + CRC16 constitutes a complete parameter block, and the parameter block is written into the binary file. After the new cyclic redundancy check CRC code is used as the target cyclic redundancy check CRC code and the target battery parameters are written into the target parameter block, a status code is returned to indicate whether the target battery parameters are successfully written into the target parameter block. If the target battery parameters are not successfully written into the target parameter block, the target parameter block is initialized and the battery parameters in the target parameter block are restored to the default parameters; if the target battery parameters are successfully written into the target parameter block, the operation process ends.
