[0046] Referring to Figure 1 , Figure 1 A flowchart of a battery abnormality detection method provided by an embodiment of the present application is shown. The method is applied to a target battery management system, specifically 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:

[0047] S101, obtaining current abnormality information of the target battery management system; the current abnormality information includes a target battery pack identifier corresponding to an abnormal battery pack represented in binary and target abnormality detail information;

[0048] In some embodiments, the operating state of the battery pack is collected by a collector in the target battery management system, and the state information collected by the collector is processed by the controller of the target battery management system to determine the abnormal battery pack and the current abnormality information corresponding to the abnormal battery pack. The current abnormality information is represented in binary form, including the target battery pack identifier corresponding to the abnormal battery pack and the target abnormality detail information. The target battery pack identifier is used to distinguish between each battery pack, and the target battery pack identifier can be a battery pack number. The target abnormality detail information refers to specific information related to the abnormality, including the target abnormality level and the target abnormality type. The target abnormality level refers to the severity of the abnormality.

[0049] In some embodiments, the target battery management system can be a BMS system such as an uninterruptible power system (UPS), a communication base station, and a power storage system.

[0050] S103, performing bit operation on the target battery pack identifier and the target abnormality detail information with preset alarm configuration information corresponding to each preset dry contact, respectively, to obtain a bit operation result corresponding to each preset dry contact; the preset alarm configuration information includes a preset battery pack identifier represented in binary, preset alarm detail information, and output polarity.

[0051] In some embodiments, the preset dry contact refers to a switch type signal contact without voltage, without polarity, and without actively providing power. Each preset dry contact corresponds to an alarm triggering strategy, i.e., preset alarm configuration information. The preset alarm configuration information is in binary form and includes preset battery pack identification, preset alarm detail information, and output polarity. The preset alarm configuration information is a combination of multiple alarm triggering conditions. The preset alarm detail information includes preset alarm level and preset alarm type. The output polarity refers to whether the preset dry contact is a normally open dry contact or a normally closed dry contact.

[0052] In some embodiments, the current abnormal information in binary form is subjected to bit operation with the preset alarm configuration information in binary form corresponding to each preset dry contact to obtain a bit operation result corresponding to each preset dry contact. The bit operation specifically refers to AND operation. The bit operation is used to determine which preset alarm configuration information corresponding to each preset dry contact matches the current abnormal information, i.e., which preset dry contact can trigger the alarm.

[0053] S105, determining a target dry contact based on the bit operation result; the preset battery pack identification corresponding to the target dry contact matches the target battery pack identification, and the preset alarm detail information corresponding to the target dry contact matches the target abnormal detail information;

[0054] In some embodiments, the preset dry contact whose preset battery pack identification matches the target battery pack identification and whose preset alarm detail information matches the target abnormal detail information is determined as the target dry contact, i.e., the dry contact triggering the alarm.

[0055] S107, outputting target alarm information based on the output polarity of the target dry contact.

[0056] In some embodiments, the state of the target dry contact is switched according to the output polarity of the target dry contact triggering the alarm, and the target alarm information is output through the state switching of the target dry contact.

[0057] In some embodiments, referring to Figure 2 , Figure 2 A flowchart of a dry contact configuration method provided by the embodiments of the present application is shown. Before the current abnormal information of the target battery management system is obtained, the method further includes:

[0058] S201, obtaining alarm triggering information corresponding to each preset dry contact; the alarm triggering information represents alarm triggering conditions corresponding to each preset dry contact in binary form;

[0059] In some embodiments, the alarm trigger information is represented in binary form, which is used to define the alarm trigger condition of the preset dry contact. Specifically, the alarm trigger information is a multi-bit unsigned integer DryContactTrigger, each bit representing a configuration information. For example, DryContactTrigger can be a 32-bit unsigned integer, wherein bit0 represents a device alarm, bit1 represents a communication alarm, bit2 represents a voltage alarm, bit3 represents an internal resistance alarm, bit4 represents a temperature alarm,..., bit11 represents a first level alarm, bit12 represents a second level alarm,..., bit16 represents a first battery pack, bit17 represents a second battery pack, and so on.

[0060] S203, mapping the alarm trigger information to a preset alarm structure corresponding to each preset dry contact, respectively, to obtain preset alarm configuration information corresponding to each preset dry contact; the preset alarm structure includes a battery pack identifier member, an alarm level member, an alarm type member, and an output polarity member.

[0061] In some embodiments, the preset alarm structure corresponding to each preset dry contact 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:

[0062] typedef struct DryContactCtrl

[0063] {

[0064] uint8 DetectRankAndOppBitMap; / / bit0~bit3: alarm level; bit7: output polarity

[0065] uint16 DetectStringBitMap; / / battery pack identifier

[0066] uint16 DetectInfoBitMap[5]; / / alarm type

[0067] } Dry_Ctrl_t;

[0068] The 8-bit DetectRankAndOppBitMap represents the alarm rank member and the output polarity member, the 16-bit DetectStringBitMap represents the battery pack identification member, and the n*16-bit DetectInfoBitMap represents the alarm type member, where n can be determined according to the total number of alarm subtypes included in each alarm type. For example, the alarm types can include device alarms, communication alarms, voltage alarms, internal resistance alarms, and temperature alarms. The voltage alarms can include a voltage too low alarm and a voltage too high alarm, and the temperature alarms can include a temperature too low alarm and a temperature too high alarm. The value of n is determined according to the number of all alarm subtypes, and the above preset alarm structure body takes n=5 as an example, that is, the number of alarm subtypes is less than or equal to 16*5=80.

[0069] In some embodiments, the alarm trigger information corresponding to each preset dry contact point is parsed and mapped to the preset alarm structure body corresponding to each preset dry contact point respectively, so as to realize the configuration of each member in the preset alarm structure body.

[0070] The embodiments of the present application map the alarm trigger information corresponding to each preset dry contact point to the preset alarm structure body corresponding to each preset dry contact point respectively, realize the configuration of the alarm trigger condition of each preset dry contact point, obtain the preset alarm configuration information corresponding to each preset dry contact point, and the preset alarm configuration information corresponding to the preset dry contact point includes the preset battery pack identification, the preset alarm detail information, and the output polarity. That is, the alarm trigger condition of the preset dry contact point can be configured as a combination of multiple conditions, so as to realize the flexible configuration of the dry contact alarm trigger condition.

[0071] In some embodiments, the preset alarm detail information includes a preset alarm rank and a preset alarm type, and the alarm trigger information is mapped to the preset alarm structure body corresponding to each preset dry contact point respectively to obtain the preset alarm configuration information corresponding to each preset dry contact point, including:

[0072] Based on the alarm trigger information, the battery pack identification member, the alarm rank member, the alarm type member, and the output polarity member corresponding to each preset dry contact point are valued respectively to obtain the preset battery pack identification, the preset alarm rank, the preset alarm type, and the output polarity corresponding to each preset dry contact point.

[0073] 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 point is assigned based on the alarm trigger information corresponding to each preset dry contact point, so as to configure the alarm trigger condition corresponding to each preset dry contact point. 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 point is configured to trigger an alarm when a first battery pack generates a first voltage alarm, that is, the trigger condition of the preset dry contact point is that the first battery pack generates a first voltage alarm.

[0074] It should be noted that each preset dry contact point corresponds to an alarm strategy, and the alarm strategy includes a plurality of alarm trigger conditions. When the plurality of alarm trigger conditions are all met, the corresponding preset dry contact point is triggered. That is, each preset dry contact point corresponds to a group of battery packs, 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, when an 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 point. 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 point is a voltage alarm. Therefore, when it is mapped to the preset alarm structure corresponding to the preset dry contact point, the bits corresponding to the two alarm sub-types of the voltage alarm and the voltage alarm included in the voltage alarm in the alarm type member, that is, DetectInfoBitMap, need to be set to 1. That is, the preset dry contact point can trigger an alarm when the first battery pack generates a first voltage alarm or the first battery pack generates a first voltage alarm.

[0075] In the embodiments of the present application, the alarm trigger information corresponding to each preset dry contact point is mapped to the preset alarm structure corresponding to each preset dry contact point, so as to configure the alarm trigger condition of each preset dry contact point, and obtain the preset alarm configuration information corresponding to each preset dry contact point. The preset alarm configuration information corresponding to the preset dry contact point includes a preset battery pack identifier, preset alarm detail information and output polarity. That is, the alarm trigger condition of the preset dry contact point can be configured as a combination of a plurality of conditions, so as to realize flexible configuration of the dry contact alarm trigger condition.

[0076] In some embodiments, the target exception detail information includes a target exception level and a target exception type, and the obtaining of the current exception information of the target battery management system includes:

[0077] obtaining current working state information of each battery pack;

[0078] determining the abnormal battery pack and initial abnormal information corresponding to the abnormal battery pack based on the current working state information; the initial abnormal information includes initial battery pack identification and initial abnormal detail information, and the initial abnormal detail information includes initial abnormal level and initial abnormal type;

[0079] converting the initial battery pack identification into the target battery pack identification represented in binary, converting the initial abnormal level into the target abnormal level represented in binary, and converting the initial abnormal type into the target abnormal type represented in binary;

[0080] determining the current abnormal information based on the target battery pack identification, the target abnormal level, and the target abnormal type.

[0081] 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, which can include current temperature information, current voltage information, current internal resistance information, etc.

[0082] 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 abnormal information corresponding to the abnormal battery pack can be determined, and the initial abnormal information includes initial battery pack identification, initial abnormal level, and initial abnormal type, wherein the initial abnormal type corresponds to the alarm sub-type, i.e., the initial abnormal type is specific to the sub-type, for example, the initial abnormal information can represent that the first battery pack has a first-level voltage over-high abnormality.

[0083] In some embodiments, the initial battery pack identification, the initial abnormal level, and the initial abnormal type included in the initial abnormal information are converted into binary representation respectively to obtain the target battery pack identification, the target abnormal level, and the target abnormal type in binary form, the bits of the target battery pack identification correspond to the bits of the battery pack identification member / preset battery pack identification, the bits of the target abnormal level correspond to the bits of the alarm level member / preset alarm level, and the bits of the target abnormal type correspond to the bits of the alarm type member / preset alarm type. Wherein, the target abnormal type corresponds to the alarm sub-type, i.e., the target abnormal type is specific to the sub-type, for example, the target abnormal type can represent a voltage over-high abnormality or a voltage over-low abnormality.

[0084] In some embodiments, an array MappingDetectInfoToRteId can be defined, which has the same size as the DetectInfoBitMap in the preset alarm structure, and is used to index the initial abnormal information stored in the register. The RTE value, i.e. the address of the register storing the initial abnormal information, is stored in the MappingDetectInfoToRteId array. Through the register address stored in the MappingDetectInfoToRteId array, the initial abnormal information corresponding to the abnormal battery pack can be obtained, and the initial abnormal information is converted into the current abnormal information corresponding to the bit of the preset alarm configuration information.

[0085] In the embodiments of the present application, the current abnormal information of the target battery management system is represented in binary form. The target dry contact triggering alarm is determined by performing bit operation between the binary form of the current abnormal information and the binary form of the preset alarm configuration information corresponding to each preset dry contact. Only bit operation is required when determining whether to trigger the alarm, which improves the efficiency of the alarm triggering determination, reduces the occupation of the processing resources, and is suitable for the embedded resource limited environment.

[0086] In some embodiments, referring to Figure 3 , Figure 3 The flowchart of the information matching method provided by the embodiments of the present application is shown in FIG. 1. The target abnormal detail information includes a target abnormal level and a target abnormal type. The preset alarm detail information includes a preset alarm level and a preset alarm type. The target battery pack identifier and the target abnormal detail information are 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, which includes:

[0087] 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;

[0088] In some embodiments, since the bits of the target battery pack identifier correspond to the bits of the preset battery pack identifier, the target battery pack identifier can be 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, i.e. (ContactValue1&Dry_Ctrl[i].DetectStringBitMap), wherein ContactValue1 is the target battery pack identifier, and i is the serial number of the preset dry contact. The first operation result is in binary form. If the first operation result is consistent with the target battery pack identifier, it indicates that the target battery pack identifier matches the preset battery pack identifier corresponding to the corresponding preset dry contact.

[0089] S303, performing an AND operation between the target abnormality rank and a preset alarm rank corresponding to each preset dry contact point to obtain a second operation result corresponding to each preset dry contact point;

[0090] In some embodiments, since the bits of the target abnormality rank correspond to the bits of the preset alarm rank, the target abnormality rank can be ANDed with the preset alarm rank corresponding to each preset dry contact point 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 rank, and i is the serial number of the preset dry contact point. The second operation result is in binary form, and if the second operation result is consistent with the target abnormality rank, it indicates that the target abnormality rank matches the preset alarm rank corresponding to the corresponding preset dry contact point.

[0091] S305, performing an AND operation between the target abnormality type and a preset alarm type corresponding to each preset dry contact point to obtain a third operation result corresponding to each preset dry contact point;

[0092] In some embodiments, since the bits of the target abnormality type correspond to the bits of the preset alarm type, the target abnormality type can be ANDed with the preset alarm type corresponding to each preset dry contact point bit by bit to obtain a third operation result corresponding to each preset dry contact point, i.e., (ContactValue3[j]&Dry_Ctrl[i].DetectInfoBitMap[j]), where ContactValue3[j] is the target abnormality type, i is the serial number of the preset dry contact point, and j is the serial number of the target abnormality type. 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.

[0093] S307, determining a bit operation result corresponding to each preset dry contact point based on the first operation result, the second operation result, and the third operation result.

[0094] In some embodiments, each preset dry contact point is polled, and a bit operation result corresponding to each preset dry contact point is determined through an AND operation between the current abnormality information and the preset alarm configuration information corresponding to each preset dry contact point. The bit operation result corresponding to each preset dry contact point includes the first operation result, the second operation result, and the third operation result.

[0095] The embodiment of the application represents the current abnormal information of the target battery management system and the preset alarm configuration information corresponding to each preset dry contact in binary form, determines the target dry contact triggering alarm by performing bit operation on the binary form of the current abnormal information and the binary form of the preset alarm configuration information corresponding to each preset dry contact, only needs bit operation when performing alarm triggering judgment, improves the alarm triggering judgment efficiency, reduces the occupation of processing resources, and adapts to the embedded resource limited environment.

[0096] In some embodiments, the preset alarm type includes at least one preset alarm sub-type, and the determination of the target dry contact based on the bit operation result includes:

[0097] In the case that the bit operation result represents that the preset battery pack identifier is consistent with the target battery pack identifier, the preset alarm level is consistent with the target abnormal level, and one of the preset alarm sub-types in the preset alarm type is consistent with the target abnormal type, the preset dry contact corresponding to the bit operation result is determined as the target dry contact.

[0098] In some embodiments, the preset dry contact with the preset battery pack identifier consistent with the target battery pack identifier, the preset alarm level consistent with the target abnormal level, and one of the preset alarm sub-types in the preset alarm type consistent with the target abnormal type is determined as the target dry contact triggering alarm. For example, if the current abnormal information represents that the first battery pack has a first level voltage over-high abnormality, a certain preset dry contact is configured to trigger alarm in the case that the first battery pack has a first level voltage alarm, the preset battery pack identifier (the first battery pack) corresponding to the preset dry contact is consistent with the target battery pack identifier (the first battery pack), the preset alarm level (the first level alarm) corresponding to the preset dry contact is consistent with the target abnormal level (the first level 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 contact is consistent with the target abnormal type (voltage over-high abnormality), that is, the current abnormal information matches the preset alarm configuration information corresponding to the preset dry contact, and the preset dry contact is the target dry contact.

[0099] The embodiment of the application represents the current abnormal information of the target battery management system and the preset alarm configuration information corresponding to each preset dry contact in binary form, determines the target dry contact triggering alarm by performing bit operation on the binary form of the current abnormal information and the binary form of the preset alarm configuration information corresponding to each preset dry contact, only needs bit operation when performing alarm triggering judgment, improves the alarm triggering judgment efficiency, reduces the occupation of processing resources, and adapts to the embedded resource limited environment.

[0100] In some embodiments, the target alarm information is output based on the output polarity of the target dry contact point, including:

[0101] determining a target state of the target dry contact point based on the output polarity of the target dry contact point; in a case where the output polarity of the target dry contact point indicates that the target dry contact point is a normally open dry contact point, the target state is that the target dry contact point is closed; in a case where the output polarity of the target dry contact point indicates that the target dry contact point is a normally closed dry contact point, the target state is that the target dry contact point is open;
