[0019] Referring to Figure 1 , Figure 1 A flowchart of a battery abnormality detection method provided by an embodiment of the present application, the method is applied to a target battery management system, specifically applied to a controller of the target battery management system, the target battery management system includes a plurality of battery packs and a plurality of preset dry contacts, the method includes: S101, obtaining current abnormal information of the target battery management system; the current abnormal information includes a target battery group identifier corresponding to an abnormal battery group and target abnormal detail information represented in binary form; In some embodiments, the running state of the battery group is collected by a collector in the target battery management system, and the state information collected by the collector is processed by a controller of the target battery management system to determine an abnormal battery group and current abnormal information corresponding to the abnormal battery group. The current abnormal information is represented in binary form and includes a target battery group identifier corresponding to the abnormal battery group and target abnormal detail information. The target battery group identifier is used to distinguish between battery groups, and the target battery group identifier can be a battery group number. The target abnormal detail information refers to specific information related to the abnormality, including a target abnormality level and a target abnormality type. The target abnormality level refers to the severity of the abnormality.

[0020] In some embodiments, the target battery management system can be an uninterruptible power system (UPS), a communication base station, a power storage system, or other BMS systems.

[0021] S103, performing a bitwise operation on the target battery group identifier and the target abnormal detail information with preset alarm configuration information corresponding to each preset dry contact point, respectively, to obtain a bitwise operation result corresponding to each preset dry contact point; the preset alarm configuration information includes a preset battery group identifier, preset alarm detail information, and output polarity represented in binary form; In some embodiments, a preset dry contact point refers to a switch-type signal contact point without voltage, without polarity, and without actively providing power.

The preset alarm configuration information is a combination of multiple alarm triggering conditions, wherein the preset alarm detail information includes a preset alarm level and a preset alarm type. The output polarity refers to whether the preset dry contact point is a normally open dry contact point or a normally closed dry contact point.

[0022] In some embodiments, the current abnormal information in binary form is subjected to a bitwise operation with the preset alarm configuration information in binary form corresponding to each preset dry contact point to obtain a bitwise operation result corresponding to each preset dry contact point. The bitwise operation specifically refers to an AND operation. The bitwise operation is used to determine which preset alarm configuration information corresponding to each preset dry contact point matches the current abnormal information, i.e., which preset dry contact point can be triggered by the current abnormal information to generate an alarm.

[0023] S105, determine a target dry contact point based on the bit operation result; the target dry contact point corresponds to a preset battery pack identifier matching the target battery pack identifier, and the target dry contact point corresponds to preset alarm detail information matching the target abnormal detail information; In some embodiments, the preset dry contact point with the preset battery pack identifier matching the target battery pack identifier and the preset alarm detail information matching the target abnormal detail information is determined as the target dry contact point, i.e. the dry contact point triggering the alarm.

[0025] In some embodiments, the state of the target dry contact point is switched according to the output polarity of the target dry contact point triggering the alarm, and the target alarm information is output through the state switching of the target dry contact point.

[0026] In some embodiments, referring to Figure 2 , Figure 2 A flowchart of a dry contact point configuration method provided by the embodiments of the present application, before the step of obtaining the current abnormal information of the target battery management system, the method further comprises: S201, obtain alarm triggering information corresponding to each preset dry contact point; the alarm triggering information represents alarm triggering conditions corresponding to each preset dry contact point in binary form; In some embodiments, the alarm triggering information is represented in binary form, which is used to define the alarm triggering conditions of the preset dry contact point. Specifically, the alarm triggering information is a multi-bit unsigned integer DryContactTrigger, each bit represents a configuration information, for example, DryContactTrigger can be a 32-bit unsigned integer, wherein bit0 represents device alarm, bit1 represents communication alarm, bit2 represents voltage alarm, bit3 represents internal resistance alarm, bit4 represents temperature alarm, …, bit11 represents first-level alarm, bit12 represents second-level alarm, …, bit16 represents the first battery pack, bit17 represents the second battery pack, ….

[0027] S203, map the alarm triggering information to the preset alarm structure corresponding to each preset dry contact point respectively to obtain preset alarm configuration information corresponding to each preset dry contact point; the preset alarm structure includes a battery pack identifier member, an alarm level member, an alarm type member and an output polarity member.

[0028] In some embodiments, the preset alarm structure corresponding to each preset dry contact point includes a battery pack identifier member, an alarm level member, an alarm type member and an output polarity member. Specifically, the preset alarm structure is as follows: typedef struct DryContactCtrl { uint8 DetectRankAndOppBitMap; / / bit0~bit3: alarm level; bit7: output polarity uint16 DetectStringBitMap; / / Battery pack identifier uint16 DetectInfoBitMap[5]; / / Alarm type Dry_Ctrl_t; Among them, the 8-bit DetectRankAndOppBitMap represents the alarm level member and the output polarity member, the 16-bit DetectStringBitMap represents the battery pack identifier member, and the n×16-bit DetectInfoBitMap represents the alarm type member. n can be determined according to the total number of alarm subtypes included in each alarm type. For example, alarm types can include device alarms, communication alarms, voltage alarms, internal resistance alarms, and temperature alarms. Among them, voltage alarms can include two alarm subtypes: low voltage alarm and high voltage alarm, and temperature alarms can include two alarm subtypes: low temperature alarm and high temperature alarm. The value of n is determined according to the number of all alarm subtypes. The above preset alarm structure takes n=5 as an example, that is, the number of alarm subtypes is less than or equal to 16×5=80.

[0029] In some embodiments, the alarm triggering information corresponding to each preset dry contact is parsed and mapped to the preset alarm structure corresponding to each preset dry contact, thereby configuring each member in the preset alarm structure.

[0030] In this embodiment, the alarm triggering information corresponding to each preset dry contact is mapped to the preset alarm structure corresponding to each preset dry contact, thereby configuring the alarm triggering conditions for each preset dry contact and obtaining the preset alarm configuration information corresponding to each preset dry contact. The preset alarm configuration information corresponding to the preset dry contact includes the preset battery pack identifier, preset alarm details and output polarity. That is, the alarm triggering conditions of the preset dry contact can be configured as a combination of multiple conditions, realizing the flexible configuration of the dry contact alarm triggering conditions.

[0031] In some embodiments, the preset alarm details include a preset alarm level and a preset alarm type. Mapping the alarm triggering information to the preset alarm structure corresponding to each preset dry contact to obtain the preset alarm configuration information corresponding to each preset dry contact includes: The battery group identification member, the alarm level member, the alarm type member and the output polarity member corresponding to each preset dry contact are respectively assigned values based on the alarm trigger information corresponding to the preset dry contact, to obtain the preset battery group identification, the preset alarm level, the preset alarm type and the output polarity corresponding to each preset dry contact.

[0032] In some embodiments, for each bit of the DryContactTrigger, 1 indicates that the corresponding configuration is turned on, and 0 indicates that the corresponding configuration is turned off. Each member in the preset alarm structure corresponding to each preset dry contact is assigned a value based on the alarm trigger information corresponding to each preset dry contact, to realize the configuration of the alarm trigger condition corresponding to each preset dry contact. For example, for the DryContactTrigger of 32 bits in the foregoing example, bit2, bit11 and bit16 are 1, which means that the preset dry contact is configured to trigger an alarm when a first battery group has a first voltage alarm, i.e., the trigger condition of the preset dry contact is that the first battery group has a first voltage alarm.

[0033] It should be noted that each preset dry contact corresponds to an alarm strategy, and an alarm strategy includes a plurality of alarm trigger conditions. When the plurality of alarm trigger conditions are all met, the corresponding preset dry contact is triggered. That is, each preset dry contact corresponds to a group of battery groups, an alarm level and an alarm type. However, since the alarm type member in the preset alarm structure is a specific alarm sub-type, the configuration of the preset alarm type is a one-to-many configuration. That is, if a certain alarm type bit in the alarm trigger information is 1, all alarm sub-types included in the alarm type need to be set to 1 when the alarm type bit is mapped to the alarm type member in the preset alarm structure corresponding to the preset dry contact. For example, for the DryContactTrigger of bit2, bit11 and bit16 being 1 in the foregoing example, it means that one of the alarm trigger conditions of the corresponding preset dry contact is a voltage alarm. When it is mapped to the alarm type member in the preset alarm structure corresponding to the preset dry contact, the bits corresponding to the two alarm sub-types of the voltage alarm and the voltage alarm included in the voltage alarm in the DetectInfoBitMap need to be set to 1, i.e., the preset dry contact can trigger an alarm when the first battery group has a first voltage alarm or the first battery group has a first voltage alarm.

[0034] The embodiment of the application maps the alarm triggering information corresponding to each preset dry contact to the preset alarm structure corresponding to each preset dry contact, realizes the configuration of the alarm triggering condition of each preset dry contact, obtains the preset alarm configuration information corresponding to each preset dry contact, and the preset alarm configuration information corresponding to the preset dry contact includes the preset battery pack identifier, the preset alarm detail information and the output polarity, that is, the alarm triggering condition of the preset dry contact can be configured as a combination of multiple conditions, and flexible configuration of the dry contact alarm triggering condition is realized.

[0036] In some embodiments, the current working state of each battery pack is collected by a collector in the target battery management system to obtain the current working state information of each battery pack, and the current working state information can include current temperature information, current voltage information, current internal resistance information, etc.

[0037] In some embodiments, by comparing the current working state information of each battery pack with the corresponding preset state threshold, the abnormal battery pack and the initial abnormality information corresponding to the abnormal battery pack can be determined, and the initial abnormality information includes an initial battery pack identifier, an initial abnormality level and an initial abnormality type, wherein the initial abnormality type corresponds to an alarm sub-type, that is, the initial abnormality type is specific to the sub-type, for example, the initial abnormality information can represent that the first battery pack has a first-level voltage overhigh abnormality.

[0038] In some embodiments, the initial battery pack identifier, the initial abnormality level and the initial abnormality type included in the initial abnormality information are respectively converted into a form represented in binary, to obtain a target battery pack identifier, a target abnormality level and a target abnormality type in binary form, the bits of the target battery pack identifier correspond to the bits of the battery pack identifier member / preset battery pack identifier, the bits of the target abnormality level correspond to the bits of the alarm level member / preset alarm level, and the bits of the target abnormality type correspond to the bits of the alarm type member / preset alarm type. The target abnormality type corresponds to the alarm sub-type, i.e., the target abnormality type is specific to the sub-type, for example, the target abnormality type can represent a voltage too high abnormality or a voltage too low abnormality.

[0039] In other embodiments, an array MappingDetectInfoToRteId can be defined, the size of the array is the same as the alarm type member DetectInfoBitMap in the preset alarm structure, for indexing the initial abnormality information, the initial abnormality information is stored in a register, and the RTE value is stored in the MappingDetectInfoToRteId array, i.e., the address of the register storing the initial abnormality information. Through the register address stored in the MappingDetectInfoToRteId array, the initial abnormality information corresponding to the abnormal battery pack can be obtained, and the initial abnormality information is converted into the current abnormality information corresponding to the bits of the preset alarm configuration information.

When performing alarm triggering judgment, only bit operation is required, which improves the alarm triggering judgment efficiency, reduces the occupation of processing resources, and adapts to the embedded resource limited environment.

[0041] In some embodiments, referring to Figure 3 , Figure 3 A flowchart of an information matching method provided by the embodiments of the present application is shown, the target abnormality detail information includes a target abnormality level and a target abnormality type, the preset alarm detail information includes a preset alarm level and a preset alarm type, and the target battery pack identifier and the target abnormality detail information are respectively subjected to AND operation with the preset alarm configuration information corresponding to each preset dry contact, to obtain the bit operation result corresponding to each preset dry contact, including: S301, the target battery pack identifier is subjected to AND operation with the preset battery pack identifier corresponding to each preset dry contact, to obtain the first operation result corresponding to each preset dry contact; In some embodiments, since the bits of the target battery pack identification correspond to the bits of the preset battery pack identification, the target battery pack identification and the preset battery pack identification corresponding to each preset dry contact point can be ANDed bit by bit to obtain a first operation result corresponding to each preset dry contact point, i.e., (ContactValue1&Dry_Ctrl[i].DetectStringBitMap), where ContactValue1 is the target battery pack identification, and i is the serial number of the preset dry contact point. The first operation result is in binary form, and if the first operation result is consistent with the target battery pack identification, it indicates that the target battery pack identification matches the preset battery pack identification corresponding to the corresponding preset dry contact point.

[0042] S303, the target abnormality level is ANDed with the preset alarm level corresponding to each preset dry contact point to obtain a second operation result corresponding to each preset dry contact point; In some embodiments, since the bits of the target abnormality level correspond to the bits of the preset alarm level, the target abnormality level and the preset alarm level corresponding to each preset dry contact point can be ANDed bit by bit to obtain a second operation result corresponding to each preset dry contact point, i.e., (ContactValue2&Dry_Ctrl[i].DetectRankAndOppBitMap), where ContactValue2 is the target abnormality level, and i is the serial number of the preset dry contact point.

The third operation result is in binary form, and if the third operation result is consistent with the target abnormality type, it indicates that the target abnormality type matches the preset alarm type corresponding to the corresponding preset dry contact point.

[0044] S307, determining a bit operation result corresponding to each preset dry joint based on the first operation result, the second operation result and the third operation result.

[0045] In some embodiments, each preset dry joint is polled, and a bit operation result corresponding to each preset dry joint is determined through an AND operation between current abnormal information and preset alarm configuration information corresponding to each preset dry joint, the bit operation result corresponding to each preset dry joint including a first operation result, a second operation result and a third operation result.

[0046] Embodiments of the present application represent current abnormal information of a target battery management system and preset alarm configuration information corresponding to each preset dry joint in binary form, and determine a target dry joint triggering an alarm by performing a bit operation between binary-form current abnormal information and binary-form preset alarm configuration information corresponding to each preset dry joint. When performing alarm triggering judgment, only a bit operation is needed, which improves alarm triggering judgment efficiency, reduces the occupation of processing resources, and adapts to embedded resource-limited environments.

For example, if current abnormal information represents that a first battery pack has a level-1 voltage over-high abnormality, a certain preset dry joint is configured to trigger an alarm in the case where the first battery pack has a level-1 voltage alarm, the preset battery pack identifier (the first battery pack) corresponding to the preset dry joint is consistent with the target battery pack identifier (the first battery pack), the preset alarm level (level-1 alarm) corresponding to the preset dry joint is consistent with the target abnormal level (level-1 abnormality), and one of the preset alarm sub-types (including voltage over-low alarm and voltage over-high alarm) in the preset alarm type corresponding to the preset dry joint is consistent with the target abnormal type (voltage over-high abnormality), i.e., the current abnormal information matches the preset alarm configuration information corresponding to the preset dry joint, and the preset dry joint is the target dry joint.
