For a clear understanding of the technical solutions of the present application, a detailed description of the prior art solutions is first provided.
In a conventional manner, when a certain function of the battery management system is upgraded, the whole battery management system is upgraded. However, when only one or a few functions need to be upgraded, the upgrading efficiency of the battery management system is reduced to a certain extent by the method that the whole battery management system needs to be upgraded.
Therefore, in the face of the technical problems of the prior art, the inventor finds out through creative research to solve the technical problem of reducing the upgrading efficiency of the battery management system in the prior art. Therefore, the battery management system is packaged into a plurality of functional modules in advance, when a certain function needs to be upgraded, only the functional module corresponding to the function needs to be upgraded, at the moment, the battery management system responds to an upgrade instruction sent by the upper computer, finds the functional module to be upgraded currently according to the identification information of the functional module to be upgraded in the upgrade file according to the upgrade file acquired from the upper computer, and upgrades the functional module according to the corresponding upgrade data, so that the function can be upgraded.

The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
In the battery management system, the functional modules include at least: the device comprises a temperature data processing module, a voltage module, a current module, a terminal product communication module, a balance module and the like.
Fig. 2 is a function upgrade method of a battery management system according to an embodiment of the present application, and as shown in fig. 2, an execution main body of the function upgrade method of the battery management system according to the embodiment is the battery management system, where the battery management system includes a plurality of packaged functional modules, and the function upgrade method of the battery management system according to the embodiment includes the following steps:
And the upgrading instruction is sent by the upper computer and is used for indicating the battery management system to upgrade.
Specifically, the upper computer may send the upgrade instruction periodically in a set period, or may send the upgrade instruction to the battery management system when triggered by the user. If the periodic sending mode is set, the user is prompted to store the upgrade file into the upper computer, and then the battery management system is upgraded according to the upgrade file. If the battery management system is in the user triggering mode, the user can temporarily store the upgrade file into the upper computer and then upgrade the battery management system.
In a possible implementation mode, before an upgrading instruction sent by an upper computer is received, when a battery management system detects that the upper computer is accessed, the address and the ID number of the upper computer are read, and if the address and the ID number of the upper computer are consistent with those stored in the battery management system, the step of receiving the upgrading instruction sent by the upper computer is executed, so that the upper computer of an original factory is used when the battery management system is upgraded, and the reliability of the upgrading process is better guaranteed.
And 102, responding to an upgrading instruction, and acquiring an upgrading file sent by an upper computer, wherein the upgrading file comprises identification information of a functional module to be upgraded and corresponding upgrading data.
After the battery management system responds to the upgrading instruction, a field effect transistor (MOS) which is charged/discharged is closed, a boot upgrading mode is entered, and data related to upgrading, namely upgrading files, are waited to be received. The upgrade file includes identification information of the functional module to be upgraded and corresponding upgrade data.
The identification information of the functional module to be upgraded is information that can be used to identify the functional module to be upgraded, and may be, for example, a serial number or a name. The upgrade data is data for upgrading the functional module to be upgraded. If there are multiple function modules to be upgraded at the same time, the upgrade file may include identification information of the multiple function modules to be upgraded and corresponding upgrade data.
The mode of obtaining the upgrade file sent by the upper computer may be that after responding to the upgrade instruction, the battery management system obtains the upgrade file from the upper computer.
And 103, determining the current functional module to be upgraded according to the identification information of the functional module to be upgraded.
The method comprises the steps of determining a unique functional module to be upgraded according to identification information of the functional module to be upgraded, and determining the current functional module to be upgraded according to the identification information of the functional module to be upgraded. When a certain function of the battery management system needs to be upgraded, the function module corresponding to the function is upgraded. Therefore, the functional module to be upgraded is determined based on the identification information of the functional module to be upgraded.
And 104, upgrading the current functional module to be upgraded according to the upgrading data to obtain the upgraded functional module.
Specifically, after the functional module to be upgraded is determined, the functional module to be upgraded can be upgraded according to the upgrade data in the upgrade file, so that the upgraded functional module is obtained.
According to the function upgrading method of the battery management system, the upgrading instruction sent by the upper computer is received; in response to an upgrading instruction, acquiring an upgrading file sent by an upper computer, wherein the upgrading file comprises identification information of a functional module to be upgraded and corresponding upgrading data; determining the current functional module to be upgraded according to the identification information of the functional module to be upgraded; and upgrading the current functional module to be upgraded according to the upgrading data to obtain the upgraded functional module. Because the battery management system is packaged with a plurality of functional modules in advance, when a certain function needs to be upgraded, the functional module corresponding to the function only needs to be upgraded, and at the moment, the battery management system responds to an upgrade instruction sent by the upper computer, finds the functional module to be upgraded currently and upgrades the functional module according to an upgrade file acquired from the upper computer, so that the upgrading of the function can be realized. Compared with the mode of upgrading the whole battery management system, the upgrading method aiming at the specific functional module can improve the efficiency of upgrading the battery management system to a certain extent.
As an alternative embodiment, the upgrade file includes: first frame data and a plurality of intermediate frame data; the identification information of the functional module to be upgraded is positioned in the first frame data, and the upgrading data corresponding to the functional module to be upgraded is positioned in each intermediate frame data; the intermediate frame data is the frame data of any frame except the first frame data in the upgrade file.
The upgrade file is a file composed of a plurality of frame data, the first frame data is frame data located in a first frame, and the middle frame data is frame data located in any frame except the first frame.
When receiving the upgrade file, the battery management system receives the upgrade file frame by frame starting from the first frame data. The identification information of the functional module to be upgraded is located in the first frame of data, so that the battery management system can immediately jump into the corresponding functional module to be upgraded according to the identification information of the functional module to be upgraded in the first frame of data after receiving the first frame of data, and the upgrading data in each intermediate frame of data can be sequentially written into the functional module to be upgraded subsequently.
In this embodiment, the upgrade file is written into the battery management system in a frame data form, so that the functional module to be upgraded can be conveniently and accurately found in time, and the functional module to be upgraded can be quickly upgraded.
As an alternative implementation, as shown in fig. 3, in this embodiment, step 104 includes the following steps:
As mentioned above, the upgrade file includes the first frame data and a plurality of intermediate frame data, and for each intermediate frame data of the upgrade file, a corresponding first check value may be calculated according to a set policy. The set strategy is a preset calculation method for calculating the first check value.
When the battery management system acquires the intermediate frame data frame by frame, the corresponding first check value is calculated according to a set strategy every time one intermediate frame data is received.
The second check value is a check value carried by each intermediate frame data, and the carrying of the second check value can be calculated according to the above setting strategy.
Data loss may occur when the upper computer transmits each intermediate frame data frame by frame, and the data loss can be understood as data loss existing in the intermediate frame data. Therefore, in order to determine whether data loss occurs in each intermediate frame data, when receiving each intermediate frame data, the battery management system compares the first check value of the intermediate frame data with the second check value of the corresponding intermediate frame data, and if the first check value of the intermediate frame data is consistent with the second check value of the corresponding intermediate frame data, it indicates that data loss does not occur in the intermediate frame data, and thus the intermediate frame data passes the check.
And step 203, upgrading the current functional module to be upgraded according to the verified intermediate frame data.
The intermediate frame data passing the verification can be used for upgrading the functional module to be upgraded. Here, the intermediate frame data that passes the verification should be understood as that there is no intermediate frame data that fails the verification, that is, all intermediate frame data pass the verification, and the functional module to be upgraded is upgraded frame by frame.
In the embodiment, a first check value corresponding to each intermediate frame data is obtained by aiming at each intermediate frame data of the upgrade file; comparing each first check value with a second check value carried by corresponding intermediate frame data to determine whether each intermediate frame data passes the check; and upgrading the current functional module to be upgraded according to the middle frame data passing the verification. When the functional module to be upgraded is upgraded, the first check value and the second check value of each intermediate frame data are compared, so that whether the intermediate frame data are lost or not can be monitored in time, and the functional module to be upgraded is favorably upgraded smoothly.
As an alternative implementation manner, in this embodiment, each intermediate frame data includes multiple bit data; step 202, more specifically comprising: and for each intermediate frame data, calculating each data except the second check value in each intermediate frame data to obtain a first check value corresponding to each intermediate frame data.
And the second check value carried by each intermediate frame data is a bit data at the rearmost of the intermediate frame data.
Specifically, for each intermediate frame data, each piece of data except for the second check value in each intermediate frame data is calculated according to a set policy. In an example one, each piece of data except the second check value in each intermediate frame data is accumulated and then averaged to obtain a corresponding first check value. In example two, the variance of each bit of data in the intermediate frame data except for the second check value is calculated to obtain the corresponding first check value. The present invention is not limited to the first example and the second example, as long as the policy is set to satisfy the discovery of data loss.
As an optional implementation manner, in this embodiment, in step 202, when determining whether each intermediate frame data passes the verification, further includes step 301, if any intermediate frame data does not pass the verification, sending a data retransmission request to the upper computer to obtain the intermediate frame data.
In the process of transmitting the intermediate frame data frame by frame, if any intermediate frame data fails to pass the verification, the battery management system sends a data retransmission request to the upper computer to acquire the intermediate frame data. If the data is lost caused by the transmission process, a data retransmission request is sent, and the intermediate frame data can be acquired under the condition of no transmission problem. If the upgrade file is a problem of the upgrade file itself, the correct upgrade file needs to be imported into the upper computer again.
After the intermediate frame data is acquired, acquiring a first check value corresponding to the intermediate frame data according to the process, comparing the first check value with a second check value of the corresponding intermediate frame data, and if the first check value passes the check, upgrading the functional module to be upgraded by using the intermediate frame data.
In this embodiment, if any intermediate frame data fails to pass the verification, a data retransmission request is sent to the upper computer to obtain the intermediate frame data. Because any intermediate frame data is required to be obtained again after the data of any intermediate frame data is not verified, the functional module to be upgraded can be ensured to be accurately upgraded.
Fig. 4 is a functional upgrade method of a battery management system according to an embodiment of the present application, and as shown in fig. 4, an execution main body of the functional upgrade method of the battery management system according to the embodiment is an upper computer. The method for upgrading the function of the battery management system provided by the embodiment includes the following steps:
The upper computer is provided with a GUI (graphical user interface) capable of being displayed to a user, and the user can select one or more functional modules to be upgraded from the GUI for upgrading. When the user determines the functional module to be upgraded, the upper computer can acquire the identification information of the functional module to be upgraded and determine the functional module to be upgraded based on the identification information.
Specifically, the mode of sending the upgrade instruction to the battery management system may be that after the functional module to be upgraded is determined, the functional module is used as a trigger time for sending the upgrade instruction, and only the upgrade instruction is sent to the battery management system first, so that the battery management system is informed of preparing to enter a boot upgrade mode.
After the upgrade instruction is sent out, if the battery management system successfully responds to the upgrade instruction, a response success instruction is sent to the upper computer, the upper computer is enabled to determine that the battery management system successfully responds to the upgrade instruction, and the upgrade file can be sent. At this time, the upper computer sends an upgrade file to the battery management system, so that the battery management system upgrades the current functional module to be upgraded according to the upgrade file to obtain the upgraded functional module. For the upgrade process of the battery management system, the definitions of the foregoing embodiments may be referred to.
According to the function upgrading method of the battery management system, the function module to be upgraded determined by a user is obtained; sending an upgrading instruction to a battery management system according to the functional module to be upgraded; if the battery management system is determined to respond to the upgrading instruction, sending an upgrading file to the battery management system so that the battery management system can upgrade the current functional module to be upgraded according to the upgrading file to obtain an upgraded functional module; the upgrading file comprises identification information of the functional module to be upgraded and corresponding upgrading data. Because the battery management system is packaged with a plurality of functional modules in advance, when a certain function needs to be upgraded, only the functional module corresponding to the function needs to be upgraded, and the upgrading aiming at the specific functional module can improve the upgrading efficiency of the battery management system to a certain extent compared with the upgrading mode aiming at the whole battery management system.
As an alternative embodiment, as shown in fig. 5, step 403, sending an upgrade file to the battery management system, includes the following steps:
The independent compiling of each functional module means that, for each functional module, the compiling is performed by a compiler of an upper computer, so as to obtain a corresponding compiled file (i.e., a hex file, also called a recordable file). The single compilation file is a compilation file obtained by independently compiling each functional module.
Before compiling each functional module, after the battery management system responds to the upgrading instruction, the upper computer acquires each functional module from the battery management system.
And 502, compiling the whole functional module to obtain a whole compiled file.
The compiling of the whole functional modules means that all the functional modules are compiled as a whole through a compiler of an upper computer, so that a compiled file is obtained. The whole compiling file is a compiling file obtained by compiling the whole of each functional module.
The disassembling technology can convert the object code into an assembly code, and related disassembling software is installed in the upper computer, namely the disassembling technology can be used for analyzing the whole compiling file to obtain the initial address of each functional module.
Wherein, the single compiled file comprises the codes of the functional modules and the byte number of the global constant. The encoding of the functional module and the number of bytes of the global constant can be used to represent the specification size of the functional module. Therefore, after the initial address of each functional module is obtained, the tail address of the functional module to be upgraded can be determined according to the initial address of the functional module to be upgraded and the specification size of the functional module to be upgraded represented by the single compiled file.
And 505, sending an upgrade file to the battery management system according to the initial address and the tail address of the functional module to be upgraded.
Specifically, after the upper computer determines the initial address and the tail address of the functional module to be upgraded, each frame data of the upgrade file is written from the initial address of the functional module to be upgraded to the tail address of the functional module to be upgraded.
In this embodiment, each functional module in the battery management system is separately compiled to obtain a corresponding single compiled file; compiling all the functional modules integrally to obtain an integral compiling file; analyzing the whole compiled file through a disassembling technology to obtain initial addresses of the functional modules; determining the tail address of the functional module to be upgraded according to the initial address of the functional module to be upgraded and the corresponding single compiled file; and sending an upgrade file to the battery management system according to the initial address and the tail address of the functional module to be upgraded. By compiling each single compiling file independently, obtaining a whole compiling file through whole compiling, and combining with a disassembling technology, the upper computer can accurately know the address of the functional module to be upgraded so as to accurately write the upgrading file into the battery management system.
As an optional implementation manner, when sending the upgrade file to the controller of the battery management system, the method further includes step 601, setting a second check value for each intermediate frame data in the upgrade file, so that the battery management system upgrades the current functional module to be upgraded according to each intermediate frame data passing the check.
And the second check value is obtained by calculating the data of each intermediate frame data except the second check value according to a set strategy by the upper computer.
In this embodiment, when the functional module to be upgraded is upgraded, the second check value is further set for each intermediate frame data, so that the battery management system compares the first check value of each intermediate data frame with the corresponding second check value, and thus, whether data loss occurs in the intermediate frame data can be timely monitored, and it is favorable for ensuring that the functional module to be upgraded is upgraded smoothly.
As an optional implementation manner, the method for upgrading functions of a battery management system further includes step 701, if a data retransmission request sent by a controller of the battery management system is received, sending the intermediate frame data that fails to pass the verification to the battery management system.
Here, if any intermediate frame data fails to be verified, the upper computer receives a corresponding data retransmission request, where the data retransmission request includes information of the intermediate frame data that fails to be verified, and may be used to determine which intermediate frame data fails to be verified, so as to conveniently and accurately send the intermediate frame data that fails to be verified to the battery management system.
In this embodiment, if a data retransmission request sent by a controller of the battery management system is received, the intermediate frame data that fails the verification is sent to the battery management system. Because any intermediate frame data is required to be obtained again after the data of any intermediate frame data is not verified, the functional module to be upgraded can be ensured to be accurately upgraded.
As an optional implementation manner, if the speed of writing the upgrade data into the processor (i.e., MCU) of the battery management system is slow, the data ring buffer may be adopted, and the upgrade data is read by using the data ring buffer, so that the processor is only responsible for the work of writing the upgrade data, thereby performing the writing and reading of the upgrade data separately, and improving the efficiency of upgrading the functional module to be upgraded.
As an optional implementation manner, after the upgrade data is completed, the battery management system exits from the boot upgrade mode, and in the initial operation process after the upgrade, the upgraded functional module of the battery management system is verified to determine whether the upgrade is successful.
Specifically, the upper computer obtains identification information of the upgraded functional module, runs the upgraded functional module, determines that the upgrade fails if the running result does not meet an expected result, and reoccurs an upgrade instruction to the battery management system so that the battery management system enters a boot upgrade mode again, and upgrades the upgraded functional module which fails to be upgraded so as to obtain the functional module which is successfully upgraded.
Here, the identification information of the same functional module does not change before and after upgrading.
Fig. 6 is a schematic structural diagram of a function upgrade apparatus of a battery management system according to an embodiment of the present application, and as shown in fig. 6, a function upgrade apparatus 60 of the battery management system according to the present embodiment is located in the battery management system, where the battery management system includes a plurality of packaged functional modules, and then the function upgrade apparatus 60 of the battery management system according to the present embodiment includes: an instruction obtaining module 61, an upgrade file obtaining module 62, a function module determining module 63, and a result obtaining module 64.
