The battery management system is divided into a BMS hard board and a BMS soft board. The BMS function mainly includes a protection function, a state estimation function, and the like. Specifically, the protection function is to stop the battery from being used when the battery parameter exceeds a certain range so as to avoid battery damage or battery fire accidents, and related parameters of the BMS protection function can also be called BMS protection parameters; the state estimation function is to estimate the SOC and/or SOH of the battery. The BMS hard board only comprises a protection function, related parameters of the protection function are generally directly set before the BMS hard board leaves a factory, and the BMS hard board is not modified after leaving the factory. The BMS soft board comprises a protection function and a state estimation function, because the state estimation is generally carried out by a Micro Control Unit (MCU), meanwhile, the MCU generally comprises communication interfaces such as a Universal Asynchronous Receiver/Transmitter (UART) and an RS485, and only supports the relevant parameter adjustment of the protection function through upper computer software. The method for adjusting the battery parameters through the upper computer software has the following problems: BMS protection parameters are complex to adjust, and the requirements on skills of related personnel are high; the battery position for operation is not fixed, the battery parameter modification management difficulty is high, and the labor cost is high; the requirements of different parameters of batteries used in different environments cannot be met, and the batteries used in operation are easy to cause operation accidents (for example, the batteries used in three volt days have overhigh temperature to cause charging protection and cannot be charged); the corresponding relation between the open-circuit voltage and the SOC of the battery in different life cycles can change, and the related art does not support the modification of the corresponding relation between the open-circuit voltage and the SOC of the battery, so that the estimation error is large.
Based on the above problems, the present application provides a method, an apparatus, a system and a storage medium for adjusting battery parameters, which adjust the battery parameters through a battery management platform to reduce the cost of adjusting the battery parameters and ensure the safety of the battery during the use.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. As shown in fig. 1, in the application scenario, the battery parameters of the battery 110 need to be reconfigured, the battery management platform 130 sends a configuration request for adjusting the battery parameters of the battery 110 to the battery management system 120, and the battery management system 120 configures the battery parameters of the battery 110 after receiving the configuration request. The specific implementation process of the battery management platform 130 through the battery management system 120 to configure the battery parameters of the battery 110 may refer to the schemes of the following embodiments.
It should be noted that fig. 1 is only a schematic diagram of an application scenario provided in an embodiment of the present application, and the embodiment of the present application does not limit the devices included in fig. 1, nor does it limit a positional relationship between the devices in fig. 1. For example, in the application scenario shown in fig. 1, a data storage device may be further included, and the data storage device may be an external memory with respect to the battery management system 120 or the battery management platform 130, or may be an internal memory integrated in the battery management system 120 or the battery management platform 130.
In the following embodiments of the present application, the BMS protection parameter adjustment and the adjustment of the SOC open-circuit voltage table in the BMS state estimation function will be described as examples.
Fig. 2 is a schematic signaling interaction diagram of a method for adjusting battery parameters according to an embodiment of the present application. As shown in fig. 2, the method of the embodiment of the present application includes:
s201, the battery management platform responds to the battery parameter reconfiguration requirement of the target battery and generates a battery parameter configuration request.
The battery parameter configuration request carries identification information of the target battery, target battery parameters to be adjusted and adjusted target parameter values.
In the embodiment of the present application, the battery parameters that the target battery needs to be reconfigured are, for example, BMS protection parameters (including alarm parameters and protection parameters) in table 1, and the present application is not limited thereto. The BMS protection parameter is, for example, a discharge overcurrent protection parameter, the maximum current of the discharge overcurrent protection parameter is set to be 50A when the battery leaves a factory, and the maximum current of the discharge overcurrent protection parameter needs to be reconfigured to be 48A after the battery is recycled for 500 times.
Illustratively, the battery parameters that the target battery needs to be reconfigured are the SOC open-circuit voltage table in the BMS state estimation function in table 2, and the SOC open-circuit voltage table in table 2 is a configuration of the battery when the battery leaves the factory, and the SOC has corresponding open-circuit voltages corresponding to different temperatures.

1％ 3.058V 3.078V 3.083V
0％ 3.002V 3.018V 3.019V
After the battery is recycled 200 times, the open circuit voltages at different temperatures corresponding to the SOC need to be reconfigured into the data shown in table 3, where table 3 is the adjusted SOC open circuit voltage table.

1％ 3.062V 3.081V 3.089V
0％ 3.003V 3.021V 3.025V
In this step, when the battery parameter of the target battery needs to be reconfigured, the battery management platform generates a battery parameter configuration request according to the battery parameter reconfiguration requirement of the target battery. Illustratively, the identification information of the target battery carried by the battery parameter configuration request is, for example, a Serial Number (SN) of the target battery; the target battery parameters to be adjusted carried by the battery parameter configuration request are, for example, the BMS protection parameters in table 1 or the SOC open-circuit voltmeter in the BMS state estimation function in table 2; the adjusted target parameter value carried by the battery parameter configuration request is, for example, the adjusted SOC open-circuit voltmeter in table 3.
Further, generating the battery parameter configuration request may include: generating a battery parameter configuration request based on a battery parameter reconfiguration instruction of a target battery; or generating a battery parameter configuration request based on a configuration task of a battery parameter of the target battery triggered by a preset trigger mechanism, wherein the preset trigger mechanism comprises at least one of timing trigger or battery event trigger.
The battery parameter reconfiguration command of the target battery may be triggered by the battery management system user interface configuration of the battery management platform, and the battery parameter configuration request is generated by configuring the BMS protection parameter needing to be reconfigured or the SOC open-circuit voltage needing to be reconfigured by the battery management system user interface of the battery management platform. Illustratively, the battery management platform supports BMS protection parameter configuration task management, and the BMS protection parameter configuration task can specify a battery, BMS protection parameters and an execution trigger mechanism contained in a task. The execution trigger mechanism includes, for example, a timing trigger and an event trigger, and the present application is not limited thereto. Illustratively, when the trigger mechanism is a timed trigger, the time of the trigger may be defined; when the trigger mechanism is event triggered, it may be defined as a battery-related event (e.g., 10 minutes after the battery is at rest, or the battery returns to a charging cabinet, etc.). A task execution unit such as a BMS protection parameter configuration in a battery management platform starts a timer and receives a battery event, and generates a battery parameter configuration request when a trigger condition is satisfied. Illustratively, the battery management platform supports SOC open circuit voltage configuration task management. The SOC open circuit voltage configuration task may specify the battery, SOC open circuit voltage, execution trigger mechanism that the task contains. The execution trigger mechanism includes a timing trigger and an event trigger, and the application is not limited thereto. When the trigger mechanism is a timing trigger, the trigger time can be defined; when the trigger mechanism is event triggering, it can be defined as a battery-related event (e.g., 10 minutes after the battery is stationary, or the battery returns to a charging cabinet, etc.). A task execution unit such as SOC open circuit voltage configuration in a battery management platform starts a timer and receives a battery event, and when a trigger condition is met, a battery parameter configuration request is generated.
Optionally, after the battery management platform generates the battery parameter configuration request, the battery management platform stores the parameter information related to the battery parameter configuration request in the memory. For example, each battery parameter configuration request corresponds to a different parameter version, which is used to provide traceability of the battery parameter configuration, where the parameter version is, for example, V3.0, and the parameter version may be a continuous version number or a discontinuous version number, which is not limited in this application. For example, after generating a configuration request of BMS protection parameters, a battery management platform may calculate and obtain a corresponding 8-bit Cyclic Redundancy Check (CRC) Check code according to a protection parameter version corresponding to the BMS protection parameters and each BMS protection parameter, and a method for specifically obtaining the CRC Check code belongs to the prior art and is not described herein again. And the battery management platform stores the SN code of the target battery, the version of the BMS protection parameter, each BMS protection parameter (consisting of a parameter identifier and an adjusted parameter value), the 8-bit CRC check code and the creation time into a database. Specifically, the storage structure of the battery management platform BMS protection parameter database is: the combination of the SN code of the target battery, the version of the BMS protection parameter, each BMS protection parameter (consisting of parameter identification and adjusted parameter value), the 8-bit CRC check code, the creation time, whether the BMS protection parameter is modified, the modification time of the BMS protection parameter and the description of the modification result of the BMS protection parameter. Illustratively, after generating a configuration request of the SOC open-circuit voltage, the battery management platform may calculate to obtain a corresponding 8-bit CRC check code according to the SOC open-circuit voltage version and the SOC open-circuit voltage item, and store the target battery SN code, the SOC open-circuit voltage version, the SOC open-circuit voltage item, the 8-bit CRC check code, and the creation time in the database. Specifically, the storage structure of the battery management platform SOC open-circuit voltage database is as follows: the combination of the target battery SN code, the SOC open-circuit voltage version, the SOC open-circuit voltage item (consisting of the cell voltage and the SOC of the battery), the 8-bit CRC check code, the creation time, whether the SOC open-circuit voltage of the BMS is modified, the SOC open-circuit voltage modification time of the BMS and the SOC open-circuit voltage modification result description of the BMS.
S202, the battery management platform sends a battery parameter configuration request to the battery management system.
Accordingly, the battery management system receives a battery parameter configuration request from the battery management platform.
The battery parameter configuration request is used for instructing the battery management system to adjust a parameter value of a target battery parameter of the target battery to a corresponding target parameter value.
Illustratively, after generating a configuration request of the BMS protection parameter, the battery management platform sends the configuration request of the BMS protection parameter to the battery management system, where the parameter carried in the configuration request of the BMS protection parameter includes a BMS protection parameter version, each BMS protection parameter (composed of a parameter identifier and a parameter value), and accordingly, the battery management system receives the configuration request of the BMS protection parameter from the battery management platform, can parse the configuration request of the BMS protection parameter, and obtain a BMS protection parameter version, each BMS protection parameter (composed of a parameter identifier and a parameter value), and the like. For example, after generating a configuration request of the SOC open-circuit voltage, the battery management platform sends the configuration request of the SOC open-circuit voltage to the battery management system, where parameters carried in the configuration request of the SOC open-circuit voltage include an SOC open-circuit voltage version, an SOC open-circuit voltage item (including SOC and open-circuit voltages corresponding to different temperatures), and accordingly, the battery management system receives the configuration request of the SOC open-circuit voltage from the battery management platform, may analyze the configuration request of the SOC open-circuit voltage, and obtain the SOC open-circuit voltage version and the SOC open-circuit voltage item.
S203, the battery management system replaces the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value.
In this step, after receiving a battery parameter configuration request from a battery management platform, the battery management system replaces the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value according to the parameter information in the battery parameter configuration request. As for how the battery management system replaces the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value, reference may be made to related technologies or subsequent embodiments, which are not described herein again.
Optionally, after the battery management system adjusts the current parameter value of the target battery parameter of the target battery to the corresponding target parameter value, the method may further include: and the battery management system sends related description information for indicating the successful adjustment of the battery parameters to the battery management platform.
For example, the related description information indicating that the battery parameter adjustment is successful may include a description of whether the battery parameter configuration is successful, a failure in the battery parameter configuration, or a success.
According to the method for adjusting the battery parameters, the battery management platform responds to the battery parameter reconfiguration requirement of the target battery to generate a battery parameter configuration request, the battery management platform sends the battery parameter configuration request to the battery management system, the battery management system receives the battery parameter configuration request from the battery management platform, and the battery management system replaces the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value. According to the method, the battery management platform is in communication connection with the battery management system, when the battery parameter is required to be adjusted, the battery management platform sends a battery parameter configuration request to the battery management system so as to automatically adjust the battery parameter, and relevant personnel do not need to carry a terminal provided with upper computer software to adjust the battery parameter on site, so that accurate adjustment of the battery parameter can be achieved at low cost, and the safety of the battery in the using process is guaranteed; in addition, the requirements on related personnel can be reduced.
On the basis of the foregoing embodiment, in consideration that the battery parameter exists in the memory and/or the AFE chip, in a specific implementation, the S203, the battery management system replaces the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value, and may further include: replacing the current parameter value of the target battery parameter in the memory with the corresponding target parameter value; and/or replacing the current parameter value of the target battery parameter in the AFE chip with the corresponding target parameter value. The automatic adjustment of the parameter value of the target battery parameter of the target battery is realized by adjusting the battery parameter in the memory and/or the AFE chip.
Illustratively, if the target battery parameter is a BMS protection parameter, replacing a current parameter value of the BMS protection parameter in the memory with a corresponding target parameter value, and replacing the current parameter value of the BMS protection parameter in the AFE chip with a corresponding target parameter value. For example, the target battery parameter is an SOC open-circuit voltage item (composed of a cell voltage and an SOC of the battery), and a current parameter value of the SOC open-circuit voltage item in the memory is replaced with a corresponding target parameter value.
In some embodiments, before the battery management system replaces the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value, the battery parameter adjustment method may further include checking the target parameter value to verify the reasonableness of the target parameter value. In this way, the step S203, in which the battery management system replaces the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value, may further include: determining whether a target parameter value of a target battery parameter of the target battery is within a corresponding parameter range; and if the target parameter value is in the corresponding parameter range, replacing the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value. For example, the parameter range corresponding to the target parameter value of the target battery parameter of the target battery may be obtained empirically. Illustratively, the target battery parameter is a BMS protection parameter, which is denoted by C1, and the battery management system may obtain a BMS protection parameter version, each BMS protection parameter (consisting of a parameter identifier and a parameter value), and the like according to the battery parameter configuration request. Assuming that the BMS protection parameter limit is represented by D1, it is checked whether the BMS protection parameter C1 is within the BMS protection parameter limit D1. It should be noted that, the BMS protection parameter limits corresponding to the BMSs of different versions may be different, the BMS protection parameter is, for example, a discharge overcurrent protection parameter, the BMS protection parameter limit corresponding to the BMS of version one is 100A, the BMS protection parameter limit corresponding to the BMS of version two is 50A, and the parameter value of the discharge overcurrent protection parameter in the battery parameter configuration request is 75A, so that it can be determined that the parameter value 75A of the discharge overcurrent protection parameter in the battery parameter configuration request is within the BMS protection parameter limit corresponding to the BMS of version one. Illustratively, the target battery parameter is the SOC open-circuit voltage, which is represented by C2, and then parameters such as SOC open-circuit voltage version, various SOC open-circuit voltage items, etc. may be obtained according to the battery parameter configuration request. Assuming that the SOC open circuit voltage limit is represented by D2, it is checked whether the SOC open circuit voltage C2 is within the SOC open circuit voltage limit D2.
Optionally, the method for adjusting the battery parameter may further include: and if the target parameter value is within the corresponding parameter range, sending related description information for indicating that the battery parameter is successfully adjusted to the battery management platform so as to prompt the battery management platform that the battery parameter is successfully adjusted.
Optionally, the method for adjusting the battery parameter may further include: and if the target parameter value is not in the corresponding parameter range, sending related description information for indicating the battery parameter adjustment failure to the battery management platform so as to prompt the battery management platform that the battery parameter adjustment fails. Exemplarily, if the target battery parameter is a BMS protection parameter, the related description information of the battery parameter adjustment failure is a protection parameter configuration failure, and the failure reason is that the parameter exceeds an allowable range; if the target battery parameter is the SOC open-circuit voltage, the related description information of the battery parameter adjustment failure is SOC open-circuit voltage configuration failure, and the failure reason is that the parameter exceeds the allowable range.
Optionally, the battery parameter configuration request carries a target version corresponding to the target battery parameter, and the method for adjusting the battery parameter may further include: if the target parameter value is within the corresponding parameter range, determining a first check code according to the target parameter value and the target version; and storing the target parameter value of the target battery parameter of the target battery and the first check code. Illustratively, the target battery parameters are BMS protection parameters, and if the parameter value of each BMS protection parameter is within the corresponding parameter range, the corresponding first CRC check code is determined according to the BMS protection parameter, the version of the BMS protection parameter, and the length of the storage area corresponding to the BMS protection parameter. The method for specifically obtaining the CRC check code belongs to the prior art, and is not described herein again. Illustratively, the target battery parameter is an SOC open-circuit voltage item (composed of a cell voltage of the battery and an SOC), and if a parameter value of the SOC open-circuit voltage item is within a corresponding parameter range, the corresponding first CRC check code is determined according to the SOC open-circuit voltage item, the SOC open-circuit voltage version and the storage area length corresponding to the SOC open-circuit voltage item. For example, after determining the first check code, the target parameter value of the target battery parameter of the target battery and the first check code may be stored in a FLASH memory (FLASH).
Further, storing the target parameter value of the target battery parameter of the target battery and the first check code may include: and storing the target parameter value of the target battery parameter of the target battery and the first check code in a first storage area. Illustratively, the memory comprises two memory areas, the two memory area selection tags are used for identifying different memory areas, and the BMS parameters of the double-memory battery are used for storing results, so that damage of the BMS caused by damage of a single memory area can be avoided. Illustratively, the target battery parameter is a BMS protection parameter, and the memory is, for example, FLASH, then the storage format of the BMS protection parameter in the FLASH is: the 1-byte storage area selects the combination of the tag, the protection parameter storage area a and the protection parameter storage area b. When the storage area selection label is 0xAA, the currently applied BMS protection parameter comes from the BMS protection parameter storage area a; and when the storage area selection flag is 0x55, the BMS protection parameter currently applied comes from the BMS protection parameter storage area b. Wherein, the protection parameter storage area structure is: the system comprises a combination of 2-byte storage area length, 2-byte BMS protection parameter versions, BMS protection parameters (consisting of parameter identifications and parameter values) and 8-bit CRC check codes, wherein the CRC check codes are obtained by calculating the storage area length, the BMS protection parameter versions and the BMS protection parameters. Illustratively, the target battery parameter is an SOC open-circuit voltage item (composed of a cell voltage of the battery, SOC), the memory is, for example, FLASH, and then the storage format of the SOC open-circuit voltage in FLASH is: the combination of the 1-byte memory area selection tag, the SOC open circuit voltage memory area c, and the SOC open circuit voltage memory area d. When the storage area selection label is 0xAA, the SOC open-circuit voltage currently applied comes from the SOC open-circuit voltage storage area c; when the memory area selection flag is 0x55, it indicates that the currently applied SOC open circuit voltage is from the SOC open circuit voltage memory area d. Wherein, SOC open circuit voltage memory area structure does: the data processing method comprises the following steps of combining the length of a 2-byte storage area, the version of 2-byte SOC open-circuit voltage, each SOC open-circuit voltage item (consisting of cell voltage and SOC), and 8-bit CRC check codes, wherein the CRC check codes are obtained by calculating the length of the storage area, the version of the SOC open-circuit voltage and each SOC open-circuit voltage item. It is understood that the first storage area is different from the storage area corresponding to the current parameter value of the target battery parameter of the target battery, for example, the storage area selection tag corresponding to the first storage area is 0x55, and the storage area selection tag corresponding to the current parameter value of the target battery parameter of the target battery is 0xAA.
In some embodiments, before the battery management system replaces the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value, the battery parameter adjustment method may further include checking the stored value of the target battery parameter of the target battery to verify the reasonableness of the stored value. In this way, the step S203, in which the battery management system replaces the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value, may further include: reading a stored value of a target battery parameter of a target battery from a first storage area; determining whether the stored value of the target battery parameter is consistent with a target parameter value of the target battery parameter; and if the stored value of the target battery parameter is consistent with the target parameter value of the target battery parameter, replacing the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value. Illustratively, the target battery parameter is a BMS protection parameter, the stored value of the BMS protection parameter of the target battery read from the first storage area includes the BMS protection parameter and a CRC check code corresponding to the BMS protection parameter, the BMS protection parameter in the stored value is represented by E1, the BMS protection parameter E1 is compared with the BMS protection parameter C1 obtained in the step S401 to determine whether the BMS protection parameter is consistent, and the CRC check code corresponding to the BMS protection parameter in the stored value is compared with the first CRC check code obtained in the step S402 to determine whether the BMS protection parameter is consistent.
Illustratively, the target battery parameter is an SOC open-circuit voltage item (composed of cell voltage and SOC of the battery), the stored value of the SOC open-circuit voltage item of the target battery read from the first storage region includes the SOC open-circuit voltage item and a CRC check code corresponding to the SOC open-circuit voltage item, the SOC open-circuit voltage item in the stored value is represented by E2, the SOC open-circuit voltage item E2 is compared with the SOC open-circuit voltage item C2 obtained in step S401 to determine whether the SOC open-circuit voltage item is consistent, and the CRC check code corresponding to the SOC open-circuit voltage item in the stored value is compared with the first CRC check code obtained from the step S402 to determine whether the SOC open-circuit voltage item is consistent.
Optionally, the method for adjusting the battery parameter may further include: and if the stored value of the target battery parameter is consistent with the target parameter value of the target battery parameter, setting a storage area selection tag corresponding to the target parameter value and the first check code as a first storage area in the memory. Illustratively, if the storage area selection tag corresponding to the target parameter value and the first check code is 0x55, 0x55 is set as the first storage area.
Optionally, the method for adjusting the battery parameter may further include: and if the stored value of the target battery parameter is consistent with the target parameter value of the target battery parameter, sending related description information for indicating the successful adjustment of the battery parameter to the battery management platform so as to prompt the battery management platform that the battery parameter is successfully adjusted.
Optionally, the method for adjusting the battery parameter may further include: and if the target parameter value is not in the corresponding parameter range, sending related description information for indicating the failure of battery parameter adjustment to the battery management platform so as to prompt the battery management platform that the battery parameter adjustment fails. Illustratively, if the target battery parameter is a BMS protection parameter, the related description information of the battery parameter adjustment failure is a configuration failure, and the failure reason is that a FLASH storage protection parameter storage area fails; if the target battery parameter is the SOC open-circuit voltage, the related description information of the battery parameter adjustment failure is configuration failure, and the failure reason is that the FLASH storage SOC open-circuit voltage storage area fails.
In some embodiments, the battery parameter configuration request carries a target version corresponding to the target battery parameter, and before the battery management system replaces the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value, the method for adjusting the battery parameter may further include checking a version number of the target version to verify the rationality of the version number. In this way, the step S203, in which the battery management system replaces the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value, may further include: acquiring a current version of a target battery parameter of a target battery; and if the version number of the target version is greater than or equal to the version number of the current version, replacing the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value. Illustratively, the target battery parameter is a BMS protection parameter, and if the version number of the target version of the BMS protection parameter is greater than or equal to the version number of the current version of the BMS protection parameter, the current parameter value of the BMS protection parameter is replaced with the corresponding target parameter value. Illustratively, the target battery parameter is an SOC open-circuit voltage item (composed of a cell voltage of the battery and an SOC), and if a version number of a target version of the SOC open-circuit voltage item is greater than or equal to a version number of a current version of the SOC open-circuit voltage item, the current parameter value of the SOC open-circuit voltage item is replaced with the corresponding target parameter value.
Optionally, the method for adjusting the battery parameter may further include: and if the version number of the target version is smaller than that of the current version, sending related description information for indicating that the adjustment of the battery parameters fails to be carried out to the battery management platform. Exemplarily, if the target battery parameter is a BMS protection parameter, the related description information of the battery parameter adjustment failure is a protection parameter configuration failure, and the failure reason is that the parameter exceeds an allowable range; if the target battery parameter is the SOC open-circuit voltage, the related description information of the battery parameter adjustment failure is SOC open-circuit voltage configuration failure, and the failure reason is that the parameter exceeds the allowable range.
Further, obtaining the current version of the target battery parameter of the target battery may include: acquiring a current parameter value of a target battery parameter of a target battery and a second check code corresponding to the current parameter value; and determining the current version of the target battery parameter of the target battery according to the current parameter value and the second check code corresponding to the current parameter value. For example, if the target battery parameter is the BMS protection parameter, the current parameter value of the BMS protection parameter and the second CRC check code corresponding to the current parameter value may be obtained from the storage area, and if the second CRC check code passes the check, the current version of the target battery parameter of the target battery may be determined. The second CRC check code is checked, for example, by obtaining a CRC check code according to the current parameter value of the BMS protection parameter and the current version of the BMS protection parameter (which may be obtained from the storage area), and comparing the CRC check code with the second CRC check code, if the two are consistent, it indicates that the second CRC check code passes the check. Illustratively, the target battery parameter is an SOC open-circuit voltage item (composed of a cell voltage of the battery and an SOC), and a current parameter value of the SOC open-circuit voltage item and a second CRC check code corresponding to the current parameter value may be obtained. If the second CRC check code passes the check, the current version of the target battery parameter of the target battery can be determined.
Further, the obtaining of the current parameter value of the target battery parameter of the target battery and the second check code corresponding to the current parameter value may include: and acquiring the current parameter value of the target battery parameter of the target battery and a second check code corresponding to the current parameter value from the second storage area. Illustratively, the target battery parameter is a BMS protection parameter, the storage area selection tag is 0xAA, and the BMS protection parameter storage area a corresponds to the storage area selection tag, that is, the second storage area, and the current parameter value of the BMS protection parameter and the second check code corresponding to the current parameter value can be acquired from the BMS protection parameter storage area a.
Optionally, the method for adjusting the battery parameter may further include: reading a storage area selection label corresponding to the current parameter value of the target battery parameter of the target battery from a memory; the second storage area is determined according to the storage area selection tag. Illustratively, the memory is a FLASH, and the FLASH includes two storage areas, which are identified by storage area selection tag identifications 0xAA and 0x55, respectively. It is to be understood that the second storage area here is different from the first storage area in the above-described embodiment. For example, if the storage area selection tag corresponding to the current parameter value of the target battery parameter of the target battery read from the memory is 0xAA, the second storage area may be determined according to 0xAA.
Optionally, after replacing the current parameter value of the target battery parameter of the target battery with the corresponding target parameter value, the method for adjusting the battery parameter further includes: and sending related description information for indicating the successful adjustment of the battery parameters to the battery management platform. For example, the related description information indicating that the battery parameter adjustment is successful may include a description of whether the battery parameter configuration is successful, a failure in the battery parameter configuration, or a success.

It is checked whether the BMS protection parameter A1 is within the BMS protection parameter limit B1. The BMS protection parameter is, for example, a discharge overcurrent protection parameter, and a maximum current corresponding to the discharge overcurrent protection parameter cannot exceed 500A. Illustratively, the target battery parameter of the target battery is an SOC open-circuit voltage item (composed of a cell voltage of the battery and an SOC), and A2 represents the SOC open-circuit voltage item, so that the battery management platform may obtain an SOC open-circuit voltage limit corresponding to the SOC open-circuit voltage item according to the SN number of the target battery, and B2 represents the SOC open-circuit voltage limit. It is checked whether the SOC open-circuit voltage term A2 is within the corresponding SOC open-circuit voltage limit B2. For example, the SOC of the SOC open circuit voltage term cannot exceed 100% and cannot be less than 0%, and the open circuit voltage needs to be between 2V and 5V.
For example, if the target parameter value is not within the corresponding parameter range, the battery parameter configuration process is terminated, such as the BMS protection parameter configuration process or the SOC open circuit voltage configuration process; if the target parameter value is within the corresponding parameter range, step S303 is executed.

In this step, after determining that the target parameter value is within the corresponding parameter range, the battery management platform sends a battery parameter configuration request to the battery management system. For a specific description that the battery management platform sends the battery parameter configuration request to the battery management system, reference may be made to the related description of S201 in the embodiment shown in fig. 2, which is not described herein again.
