[0073] The alarm suppression method based on the BMS battery management system provided by the present disclosure effectively avoids the repeated reporting of alarm data, which not only simplifies alarm management, but also helps operation and maintenance personnel locate the root cause of the problem more quickly and accurately.

[0074] The present disclosure provides an alarm suppression method based on a BMS battery management system. The BMS battery management system receives first alarm information of a battery cell, stores the first alarm information in a target database, and reports the first alarm information to a target system. If the BMS battery management system receives second alarm information of a battery cluster, it determines whether the battery cell is one of a first plurality of battery cells constituting the battery cluster. If the battery cell is one of the first plurality of battery cells constituting the battery cluster, it determines whether the type of the first alarm information in the target database is the same as the type of the second alarm information. If the type of the first alarm information is different from the type of the second alarm information, it stores the second alarm information in the target database and reports the second alarm information to the target system. If the BMS battery management system receives third alarm information of a battery stack, it determines whether the battery cell is one of a second plurality of battery cells constituting the battery stack, the battery stack being composed of a plurality of battery clusters composed of the second plurality of battery cells, and determines whether the battery cluster is one of the plurality of battery clusters constituting the battery stack. Whether to store the third alarm information in the target database and report the third alarm information to the target system is determined based on the judgment results of whether the battery cell is one of the second plurality of battery cells and whether the battery cluster is one of the plurality of battery clusters. Compared with related technologies, the second alarm information is filtered and the third alarm information is filtered using the first alarm information. In addition, the third alarm information is also filtered based on the second alarm information. The second alarm information and the third alarm information that pass the screening are reported, thereby reducing the amount of alarm data reported while retaining hierarchical monitoring of different structural levels of the battery.

[0075] As a refinement of the embodiment of the present disclosure, when determining whether to store the third alarm information in the target database and report the third alarm information to the target system according to the judgment result of whether the battery cell is one of the second plurality of battery cells and whether the battery cluster is one of the plurality of battery clusters in step 106, the following implementation method may also be adopted but not limited to, for example: if the battery cell is one of the second plurality of battery cells constituting the battery stack and the battery cluster is not one of the plurality of battery clusters constituting the battery stack, then determine whether the type of the first alarm information in the target database is the same as the type of the third alarm information; if the type of the first alarm information is different from the type of the third alarm information, then store the third alarm information in the target database and report the third alarm information to the target system; if the battery cell is not one of the second plurality of battery cells constituting the battery stack and the battery cluster is a group If the battery cell is one of the multiple battery clusters constituting the battery stack, then determine whether the type of the second alarm information in the target database is the same as the type of the third alarm information; if the type of the second alarm information is different from the type of the third alarm information, store the third alarm information in the target database and report the third alarm information to the target system; if the battery cell is one of the second multiple battery cells constituting the battery stack and the battery cluster is one of the multiple battery clusters constituting the battery stack, then determine whether the type of the first alarm information is the same as the type of the third alarm information and determine whether the type of the second alarm information is the same as the type of the third alarm information; if the type of the first alarm information is different from the type of the third alarm information and the type of the second alarm information is different from the type of the third alarm information, store the third alarm information in the target database and report the third alarm information to the target system.

[0076] As a refinement of the above embodiment, after determining whether the type of the first alarm information is the same as the type of the third alarm information and determining whether the type of the second alarm information is the same as the type of the third alarm information, the method can also adopt but is not limited to the following implementation methods, including: if the type of the first alarm information is different from the type of the third alarm information and the type of the second alarm information is the same as the type of the third alarm information, then discard the third alarm information; if the type of the first alarm information is the same as the type of the third alarm information and the type of the second alarm information is different from the type of the third alarm information, then discard the third alarm information; if the type of the first alarm information is the same as the type of the third alarm information and the type of the second alarm information is the same as the type of the third alarm information, then discard the third alarm information.

[0077] As a refinement of the above embodiment, when executing step 106 to determine whether to store the third alarm information in the target database and report the third alarm information to the target system based on the judgment result of whether the battery cell is one of the second plurality of battery cells and whether the battery cluster is one of the multiple battery clusters, the following implementation method can also be adopted but not limited to, for example: if the battery cell is not one of the second plurality of battery cells and the battery cluster is not one of the multiple battery clusters, the third alarm information is stored in the target database and the third alarm information is reported to the target system.

[0078] As a refinement of the above embodiment, after executing step 102 to determine whether the battery cell is one of the first plurality of battery cells constituting the battery cluster, the method may also adopt but is not limited to the following implementation methods, including: if the battery cell is not one of the first plurality of battery cells constituting the battery cluster, then storing the second alarm information in the target database and reporting the second alarm information to the target system.

[0079] As a refinement of the above embodiment, after executing step 103 to determine whether the type of the first alarm information in the target database is the same as the type of the second alarm information, the method can also adopt but is not limited to the following implementation methods, including: if the type of the first alarm information is the same as the type of the second alarm information, then the second alarm information is discarded.

[0080] Figure 2 A schematic diagram of the internal structure of a battery provided by an embodiment of the present disclosure. Figure 2 As shown, battery stack A and battery stack B, arr refers to the battery stack. Since the structural layout principle of battery stack A and battery stack B is the same, Figure 2 Only battery stack A is expanded. Battery stack A consists of battery clusters A1, A2, and A3. "clu" represents a battery cluster, each consisting of two battery cells, and "cell" represents a battery cell. MQTT stands for Message Queuing Telemetry Transport Protocol, a lightweight communication protocol based on a publish / subscribe model. Data reporting soft probes are pre-installed in the battery stack, battery clusters, and battery cells, allowing data to be uploaded to the data collection center using a topic publish / subscribe model.

[0081] In order to facilitate the understanding of the method steps involved in the embodiment of the present disclosure, this embodiment is combined with Figure 2 An exemplary description is provided, including: setting up a battery comprising the following components: a battery pack comprising multiple battery modules, each battery module comprising multiple battery cells, wherein the specific structure of the battery includes, but is not limited to, a battery pack comprising three battery modules, each battery module comprising four battery cells. If a battery cell in the battery overheats for some reason, reaching 75°C, and the battery cell alarm threshold set by the BMS is 70°C, the processing methods based on the hierarchical monitoring mechanism in the relevant technology include:

[0082] (1) Battery Cell Level: The temperature of a battery cell A reaches 75°C, exceeding the alarm threshold of 70°C. The temperature probe on battery cell A detects this high temperature and immediately reports a "Battery Cell A Temperature Over High" alarm.

[0083] (2) Battery Module Level:

[0084] Battery cluster B contains battery cell A. The temperatures of the other battery cells in the cluster are relatively normal, but the high temperature of battery cell A causes the average or maximum temperature of the entire battery cluster to exceed the alarm threshold. The temperature probe on battery cluster B detects that the average or maximum temperature of the cluster has exceeded the limit and reports a "Battery cluster B temperature is too high" alarm.

[0085] (3) Battery Pack Level:

[0086] The battery stack contains multiple battery clusters, and the temperature of battery cluster B has exceeded the alarm threshold. The temperature probe on the battery stack detects that the average temperature of the entire stack or the temperature of certain areas exceeds the alarm threshold and reports a "battery stack temperature too high" alarm.

[0087] When processing alarm information based on the hierarchical monitoring mechanism, the overly high temperature of a single battery cell, A, resulted in the duplication of the following alarms: an overtemperature alarm for battery cell A, an overtemperature alarm for battery cluster B containing battery cell A, and an overtemperature alarm for the battery stack containing battery cluster B. All three alarms were of the same type: overtemperature alarms.

[0088] Compared with the process of processing alarm information based on the above-mentioned hierarchical monitoring mechanism, if the temperature of a battery cell in the battery is too high for some reason and reaches 75°C, and the battery cell alarm threshold set by the BMS battery management system is 70°C, the specific steps of using the alarm suppression method based on the BMS battery management system proposed in this disclosure to process the alarm information are as follows:

[0089] (1) Alarm generation and preliminary detection:

[0090] When the temperature probe of battery cell A detects that the temperature is too high, the BMS will generate a "battery cell A temperature is too high" alarm. At the same time, battery cluster B and the battery stack also detect that the temperature is too high and will generate corresponding alarms.

[0091] (2) Alarm reporting order and suppression judgment:

[0092] The BMS battery management system processes alarms in a bottom-up order, that is, it processes the battery cell level first, then the battery cluster level, and finally the battery stack level.

[0093] (3) Battery cell level alarm processing:

[0094] Check the alarm of battery cell A. Since no parent alarm exists at this time, the alarm of "battery cell A temperature is too high" is reported.

[0095] (4) Battery cluster level alarm processing:

[0096] When processing the alarm for battery cluster B, the BMS checks its existing sub-alarms and discovers that a "Battery Cell A Overtemperature" alarm already exists. Based on the BMS's alarm suppression method, the BMS decides not to report the "Battery Cluster B Overtemperature" alarm because it has already been overwritten by its sub-alarm.

[0097] (5) Battery stack level alarm processing:

[0098] When processing the battery stack alarm, the BMS checks existing child alarms. It discovers an existing "Battery Cell A Overtemperature" alarm. The BMS then checks the parent-child alarm relationship and determines that the battery stack alarm is overwritten by its child alarms (battery cluster B and battery cell A). Therefore, the "Battery Stack Overtemperature" alarm is no longer reported. Ultimately, the BMS reports only the following alarm: Battery Cell A Overtemperature.

[0099] The BMS-based alarm suppression method provided in this disclosure can also be applied to other technical fields, such as smart home management systems (applied to device monitoring and alarm management at different levels within a smart home to avoid duplicate alarms. For example, hierarchical alarm suppression for devices such as temperature sensors and fire alarms) and industrial automation (applied to machine monitoring and fault alarms at different levels within industrial automation equipment to ensure non-duplication of alarm information between devices at different levels). By integrating with new application areas, the scope of data collection and management can be expanded, enabling more functionality.

[0100] In summary, the embodiments of the present disclosure can achieve the following effects:

[0101] 1. The second alarm information and the third alarm information are filtered through the first alarm information. In addition, the third alarm information needs to be filtered according to the second alarm information. The second alarm information and the third alarm information that pass the screening are reported, which reduces the amount of alarm data reported and retains the hierarchical monitoring of different structural levels of the battery.

[0102] 2. The BMS-based alarm suppression method provided in this disclosure can significantly reduce the false alarm rate, eliminate redundant alarm information, and reduce the workload of alarm processing. Accurate problem location and hierarchical alarm management enable rapid problem location and resolution, improving BMS maintenance efficiency and response speed.

[0103] Corresponding to the aforementioned BMS-based alarm suppression method, the present invention also provides a BMS-based alarm suppression device. Since the device embodiment of the present invention corresponds to the aforementioned method embodiment, details not disclosed in the device embodiment can be referred to the aforementioned method embodiment and will not be further described in this invention.
