The exception handling method provided by the application can be applied to any data processing capacity processing equipment, and the equipment can be local computing equipment or cloud computing equipment deployed at the cloud end.

It should be noted that the computer program may be a stand-alone computer program, or may be a functional module, a plug-in, an applet, or the like integrated with other programs.

It is understood that the exception handling method provided by the present application may include, but is not limited to, application to the application environment shown in fig. 1.

As shown in fig. 1, the server 101 may be connected to the BMS102 of the vehicle through a wireless communication technology such as 4G, 5G, and the like, the BMS102 may report the alarm information, if the alarm level corresponding to the alarm information is a first level, the server 101 may monitor a target index according to an alarm type indicated by the alarm information, perform an abnormal alarm for the target index when the target index satisfies a first preset alarm condition, monitor a derivative index of the target index when the target index does not satisfy the first preset alarm condition, and perform an abnormal alarm for the derivative index when the derivative index satisfies a second preset alarm condition.

Next, the exception handling method provided in the embodiment of the present application is described in detail from the perspective of the server.

Referring to fig. 2, a flow chart of an exception handling method is shown, which comprises:

s201: when alarm information of a battery management system is received, if the alarm grade corresponding to the alarm information is a first grade, monitoring a target index according to the alarm type indicated by the alarm information.

The battery management system has a battery state monitoring function, when the battery state is monitored to be abnormal, alarm information can be generated, the server can determine an alarm level corresponding to the alarm information according to the alarm information, when the alarm level is a first level which is relatively low, a target index can be monitored according to an alarm type indicated by the alarm information, and the target index is specifically an index matched with the alarm type.

It should be noted that the first level is a level with a relatively low alarm level, for example, in an example, the alarm level has five levels in total, and the first level may be the lowest two or three of the five levels, and so on. The second level corresponding to the first level is a level with a relatively higher level of the imaginary finger, such as the highest one, the highest two, or the highest three of the five levels.

For ease of understanding, the following description is made with reference to specific examples.

In one example, the alarm level may be a first level, and the alarm type may be a battery high temperature, so that the server may monitor the battery highest temperature according to the alarm type, that is, the target index at this time may be the battery highest temperature.

In another example, the alarm level is a first level, and the alarm type may be that the cell voltage uniformity is poor, so that the server may monitor the cell voltage difference according to the alarm type, that is, the target index at this time may be the cell voltage difference.

It should be noted that, the above are only some specific examples of the battery alarm type, the battery alarm type may also include other team members, and the corresponding target indexes are not limited to the above-mentioned maximum battery temperature and the above-mentioned cell differential pressure.

S202: and when the target index meets a first preset alarm condition, performing abnormal alarm aiming at the target index.

In this embodiment, the server first monitors the target index, and if the target index meets a first preset alarm condition, it indicates that the target index is actually abnormal, and the server may directly alarm for an abnormality of the target index.

In a specific implementation, the first preset alarm condition may be that a target index reaches an index threshold corresponding to the target index in N consecutive monitoring periods, that is, a target index threshold, where N is a positive integer greater than 1, and may be set according to an actual requirement, as an example, N may be set to 3, that is, when the target index reaches the corresponding target index threshold in 3 consecutive monitoring periods, it is determined that the target index is abnormal, and an abnormal alarm may be performed on the target index to prompt a user that the target index is abnormal.

Of course, in some possible implementation manners, the first preset alarm condition may also be that the target index has at least M monitoring periods within L monitoring periods, where L and M are positive integers greater than 1, and L is greater than M, where the M reaches an index threshold corresponding to the index, that is, a target index threshold. As an example, L may be set to 5, and M may be set to 4, that is, at least 4 monitoring periods in 5 monitoring periods all reach the corresponding target index threshold, for example, if the target index reaches the target index threshold in the 1 st, 2 nd, 4 th, and 5 th monitoring periods, it is determined that the target index is abnormal, and the server may perform an abnormality alarm for the target index to prompt the user that the target index is abnormal.

S203: and when the target index does not meet the first preset alarm condition, monitoring a derivative index of the target index.

In practical application, when the target index does not meet the first preset alarm condition, no abnormality is caused, and the server can further expand monitoring to determine the true cause of the abnormality. Specifically, the server may continuously monitor the derived index of the target index, thereby determining the true reason why the BMS sends the alarm information.

For ease of understanding, a battery high temperature alarm and a cell voltage consistency difference alarm are exemplified.

In one example, when the alarm type is a high temperature of the battery, the target index is a maximum temperature of the battery, and the derivative index of the target index may be at least one of a temperature difference of the battery, a potential difference of a temperature of the probe, a standard deviation of the temperature of the probe, and a temperature rise rate of the battery. In practical application, the server can monitor the battery temperature difference, the probe temperature middle potential difference, the probe temperature standard difference and the battery temperature rise rate, so that the monitoring comprehensiveness is guaranteed, and the phenomenon of alarm leakage is avoided.

In another example, when the alarm type is that the voltage consistency of the battery cells is poor, the target index is the voltage difference of the battery cells, and the derivative index of the target is at least one of the potential difference in the cell voltage, the increase rate of the voltage difference and the extreme value of the cell voltage. And the server can monitor the potential difference in the cell voltage, the increase rate of the pressure difference and the extreme value of the cell voltage according to the high-temperature alarm type of the battery, so that the monitoring comprehensiveness is ensured, and the phenomenon of alarm leakage is avoided.

S204: and when the derived index meets a second preset alarm condition, carrying out abnormal alarm aiming at the derived index.

In this embodiment, the server continuously monitors the derived index of the target index, and if the derived index meets the second preset alarm condition, it indicates that the derived index is abnormal, and the server may alarm for an abnormality of the derived index.

The second preset alarm condition may be that a derivative index of the target index reaches an index threshold corresponding to the derivative index in N consecutive monitoring periods, that is, a derivative index threshold, where N is a positive integer greater than 1, and may be set according to an actual requirement, as an example, N may be set to 3, that is, all the derivative indexes in 3 consecutive monitoring periods reach the corresponding derivative index threshold, and then it is determined that the derivative index is abnormal, and an abnormal alarm may be performed on the derivative index to prompt a user that the derivative index is abnormal.

Certainly, in some possible implementation manners, the second preset alarm condition may also be that at least M monitoring periods of derived indicators of the target indicator in L monitoring periods reach an indicator threshold corresponding to the indicator, that is, a derived indicator threshold, where L and M are positive integers greater than 1, and L is greater than M. As an example, L may be set to 5, and M may be set to 4, that is, at least 4 monitoring periods within 5 monitoring periods all reach the corresponding derivative indicator threshold, for example, if the derivative indicator reaches the derivative indicator threshold in the 1 st, 2 nd, 4 th, and 5 th monitoring periods, it is determined that the derivative indicator is abnormal, and the server may perform an abnormality alarm for the derivative indicator to prompt the user that the derivative indicator is abnormal.

Based on the first preset alarm condition and the second preset alarm condition, in some possible implementations, the alarm condition may be set as follows:

one way is that the index reaches an index threshold corresponding to the index in N continuous monitoring periods, wherein N is a positive integer greater than 1; alternatively, the first and second electrodes may be,

in another mode, at least M monitoring periods of an index in L monitoring periods reach an index threshold corresponding to the index, where L and M are positive integers greater than 1, and L is greater than M.

It should be noted that the index threshold of each index, such as the target index threshold or the derived index threshold, may be determined according to the battery history data, for example, when the target index is the battery highest temperature, the server may perform a statistical operation according to the battery history data, such as the battery highest temperature data of the battery in the last year, such as counting the average value and the variance of the above battery highest temperature data, and determine the battery highest temperature threshold based on the average value and the variance.

Considering that batteries with the same attributes have a certain reference value like model batteries, the server may determine the index threshold according to the battery history data and the battery history data corresponding to the batteries with the same attributes. The determination of the index threshold based on the battery history data of the current battery and the battery with the same attribute is similar to the determination of the index threshold based on the battery history data of the current battery, and is not repeated herein.

It should be noted that, when a plurality of derived indicators in the monitored derived indicators reach corresponding threshold values, the server may further increase the abnormal level according to the plurality of derived indicators to enhance the reminding function.

In view of the above, an embodiment of the present application provides an exception handling method, in the method, when receiving alarm information of a battery management system, if an alarm level corresponding to the alarm information is a first level, monitoring a target index matched with an alarm type according to the alarm type indicated by the alarm information, when the target index meets a first preset alarm condition, directly performing exception alarm for the target index, when the target index does not meet the first preset alarm condition, monitoring a derivative index of the target index, and when the derivative index meets a second preset alarm condition, performing exception alarm for the derivative index. On one hand, when the target index meets the first preset alarm condition, the alarm is not received, namely the alarm is given, so that the false alarm rate is reduced, on the other hand, when the target index does not meet the first preset alarm condition, the derived index is monitored, and the derived index is subjected to abnormity alarm when the derived index meets the second preset alarm condition, so that the battery abnormity can be truly reflected, and effective information is provided for a user.

In the situation, the server can monitor the target index corresponding to the alarm type and directly expand the derivative index of the monitored target index, and does not need to monitor the derivative index when the target index does not meet the first preset alarm condition.

The following describes in detail the abnormality processing method in the case where the alarm level is high.

Referring to the flow chart of the exception handling method shown in fig. 3, the method includes:

s301: when the alarm information of the BMS is received, if the alarm grade is the second grade, monitoring a target index and a derivative index of the target index according to the alarm type indicated by the alarm information.

Wherein, the second grade refers to the grade with higher alarm grade, which is described in detail with reference to the above related content. Because the alarm level is higher, the abnormal level is possibly more serious, and therefore the server can monitor the target index and the corresponding derived index according to the alarm type indicated by the alarm information.

For ease of understanding, the following description is made in conjunction with a specific example.

In an example, the alarm level is a second level, the alarm type may be an insulation alarm, at this time, the server may monitor a resistance value of the insulation resistor, that is, the target index is the resistance value of the insulation resistor, and in addition, the server expands and monitors a derivative index corresponding to the resistance value of the insulation resistor, where the derivative index specifically includes at least one of a plug-and-pull gun state, a battery charging state, a vehicle speed, a total battery current, a probe temperature range, a cell voltage range, and a cell voltage range increase rate.

In practical application, the server can monitor derived indexes such as a plug-pull gun state, a battery charging state, a vehicle speed, a battery total current, a probe temperature range difference, a cell voltage range difference and a cell voltage range difference increase rate, so that monitoring comprehensiveness is guaranteed, and alarm leakage is avoided.

S302, when at least one of the target index and the derived index of the target index is abnormal, an abnormal alarm is given according to the abnormal index.

Because the alarm level is higher, when the server finds that at least one index of the target index and the derived index of the target index is abnormal in the monitoring process, the server carries out abnormal alarm aiming at the abnormal index.

Taking an insulation alarm as an example, the server monitors the resistance value of the insulation resistor, the state of a plug gun, the charging state of the battery, the vehicle speed, the total current of the battery, the extreme difference of the temperature of the probe, the extreme difference of the voltage of the battery cell and the increase rate of the extreme difference of the voltage of the battery cell, and when the charging state of the battery in the indexes is abnormal, the server gives an abnormal alarm according to the index of the charging state of the battery.

In some possible implementation manners, if the insulation resistance alarm occurs at the moment of inserting and pulling the gun, the series of indexes are continuously monitored, and if one of the series of indexes exceeds a corresponding threshold value, the server can perform highest-level abnormal alarm; and if the insulation resistance alarm happens at the moment of not plugging the gun, directly entering an insulation abnormity alarm.

As can be seen from the above, the embodiment of the present application provides an exception handling method, which introduces a hierarchical exception handling mechanism, and specifically, when receiving alarm information of a BMS, if the alarm level is a second level, a target indicator and a derived indicator of the target indicator are monitored according to an alarm type indicated by the alarm information, and when at least one of the target indicator and the derived indicator of the target indicator is abnormal, an exception alarm is performed for the abnormal indicator. Therefore, the false alarm rate can be reduced, the real abnormal reason can be reflected, and effective information can be provided for the user so that the user can make a decision in time.

Based on the above specific implementation manners of the exception handling method provided in the embodiments of the present application, the embodiments of the present application also provide a corresponding exception handling device.
