Description

Technical Field

[0001] This application relates to the technical field of battery modules, and more particularly, to a method, apparatus, electronic device, and computer-readable storage medium for fault handling of a battery module. Background Art

[0002] New energy vehicle batteries generally consist of multiple battery modules, and each battery module contains multiple battery cell lines. Once a battery cell line drops out, it will cause abnormal changes in the voltage data adjacent to the battery cell line, with one being high and the other being low. Such abnormal data will cause a deviation in the voltage of the battery pack, such as incorrect maximum and minimum voltage judgments and incorrect calculation of the state of charge of the battery, which has a greater impact on battery health monitoring.

[0003] However, due to the large number of battery cell lines, it is laborious to find when a fault occurs, and incorrect searches often occur, delaying time and causing a sharp increase in costs. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a method, apparatus, electronic device, and computer-readable storage medium for fault handling of a battery module, which improves the efficiency of fault detection, reduces the error rate of fault detection, and saves labor costs and time costs.

[0005] In a first aspect, an embodiment of this application provides a method for fault handling of a battery module, the method comprising:

[0006] Obtaining the current time and the fault reporting time of a fault timer of the battery module;

[0007] If the current time of the fault timer has not reached the fault reporting time of the fault timer, obtaining the input flag bit corresponding to the fault timer;

[0008] Performing a clearing operation on the fault timer according to the Boolean type of the input flag bit.

[0009] In the above implementation process, if the current time of the fault timer has not reached the reporting time of the fault timer, the input flag bit of the fault timer is also obtained, and the fault timer corresponding to the input flag bit is updated and cleared according to the Boolean type of the input flag bit, improving the efficiency of fault detection of the battery module.

[0010] Further, the step of performing a clearing operation on the fault timer according to the Boolean type of the input flag bit includes:

[0011] Determining whether the Boolean type of the input flag bit is true;

[0012] If so, update the fault timer to obtain the updated fault update time, and clear the recovery timer according to the fault update time;

[0013] If not, clear the fault timer according to the time data of the previous fault timer corresponding to the fault timer.

[0014] In the above implementation process, the fault timer is updated or cleared according to the Boolean type of the input flag bit, ensuring that faults can be eliminated in a timely manner and improving the fault handling efficiency.

[0015] Further, the step of clearing the fault timer according to the fault update time includes:

[0016] Determine whether the fault update time reaches the fault reporting time;

[0017] If so, clear the recovery timer.

[0018] In the above implementation process, faults can be eliminated in a timely manner, ensuring the cleared state of the fault timer and facilitating the elimination of the next fault.

[0019] Further, the step of clearing the fault timer according to the time data of the previous fault timer corresponding to the fault timer includes:

[0020] Determine whether the time data is greater than zero;

[0021] If not, clear the fault timer.

[0022] In the above implementation process, the time data of the front and back two fault timers is judged, and the change situation of the fault timer is obtained in a timely manner, which can make the clearing operation more accurate.

[0023] Further, after the step of obtaining the current time and the fault reporting time of the fault timer of the battery module, it further includes:

[0024] If the current time of the fault timer reaches the fault reporting time of the fault timer, obtain the input flag bit corresponding to the fault timer;

[0025] Obtain the Boolean type of the input flag bit;

[0026] Clear the fault timer according to the Boolean type.

[0027] In the above implementation process, according to the Boolean type of the input flag bit, the fault timer corresponding to the input flag bit is updated and cleared, the detection and processing of the fault timer are completed, the fault detection efficiency of the battery module is improved, the error rate of the fault detection is reduced, and the labor cost and time cost are saved.

[0028] Further, the step of clearing the fault timer according to the Boolean type includes:

[0029] Judge whether the Boolean type is false;

[0030] If so, update the recovery timer to obtain the updated recovery update time, and clear the fault timer according to the recovery update time;

[0031] If not, clear the recovery timer.

[0032] In the above implementation process, the recovery timer corresponding to the input flag bit is updated and cleared according to the fault timer, so that the judgment of the recovery timer needs to be added when the fault is cleared, which can reduce errors and make the fault clearing more accurate.

[0033] Further, the step of clearing the fault timer according to the update time includes:

[0034] Obtain the recovery reporting time of the recovery timer;

[0035] Judge whether the recovery update time reaches the recovery reporting time;

[0036] If so, clear the fault timer.

[0037] In the above implementation process, the fault timer is cleared according to the recovery timer, which ensures that the fault timer can also be based on the recovery reporting time of the recovery timer, reduces the fault handling time, and improves the efficiency.

[0052] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0053] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present application, the terms "first", "second", etc. are only used for descriptive distinction and cannot be construed as indicating or implying relative importance.

[0054] The specific implementation manners of the present application will be further described in detail below with reference to the drawings and embodiments. The following embodiments are used to illustrate the present application, but are not used to limit the scope of the present application.

[0055] Embodiment 1

[0056] Figure 1 is a schematic flowchart of a fault handling method for a battery module provided by an embodiment of the present application. As Figure 1 shown, the method includes:

[0057] S1, obtaining the current time and the fault reporting time of the fault timer of the battery module;

[0058] S2, if the current time of the fault timer has not reached the fault reporting time of the fault timer, obtaining the input flag bit corresponding to the fault timer;

[0059] S3, clearing the fault timer according to the Boolean type of the input flag bit.

[0060] In the above implementation process, if the current time of the fault timer has not reached the reporting time of the fault timer, the input flag bit of the fault timer is also obtained, and the fault timer corresponding to the input flag bit is updated and cleared according to the Boolean type of the input flag bit, improving the fault detection efficiency of the battery module.

[0061] An automotive battery generally consists of multiple battery modules, and each battery module contains multiple cell wires. Once a cell wire drops off, it will cause abnormal changes in the voltage data adjacent to the sampling wire, with one high and one low. This abnormality will cause a deviation in the voltage of the battery pack. The embodiments of the present application perform fault handling on the fault timer corresponding to the cell wire. At the same time, it can also detect the collected data (i.e., sampling data) containing the abnormality of the wire drop, accurately determine the position of the wire drop, and can also perform fault recovery on the fault of the cell wire drop.

[0062] In a possible implementation, before the step of obtaining the current time and the fault reporting time of the fault timer of the battery module, it further includes:

[0063] Merge the fault flag bits of the first sampling line and the second sampling line of each module in the sampled data to obtain preprocessed sampled data. This can ensure that errors are not easily occurred during fault handling and facilitate calculations.

[0064] The sampled data includes various data of multiple cell lines and various data of cell line disconnection, such as model, voltage, etc. The fault flag bit of the sampling line is the specific position of the collected cell line. For the convenience of data processing, before the input filter, it is usually necessary to merge the fault flag bits of the first sampling line and the second sampling line in the module and then input them into the filter to ensure that the dimension of the input flag bit of the subsequent obtained fault timer is the same as the dimension of the cell line.

[0065] Before each start, the total fault flag bit needs to be cleared to avoid the situation where the fault flag bit cannot be self-eliminated. When a detection is completed, that is, the judgment of the status of all cell lines at the current moment is completed, the fault timer is incremented or decremented by one. Then the detection of the next moment is carried out.

[0066] In the filter, when the Boolean type of the input flag bit is true, only increment the fault timer of the current input flag bit. This ensures that when the fault is restored, only the fault timer of the current input flag bit is cleared.

[0067] When it is judged that the Boolean type of the current input flag bit is true, perform invalid value processing on the output data corresponding to the current input flag bit and the next input flag bit. When the fault timer reaches the fault reporting time, the output data corresponding to the current input flag bit and the next input flag bit is an invalid value, the Boolean type of the fault flag bit corresponding to the current input flag bit and the next input flag bit is true, the fault timer is incremented by one of the fault reporting time, and the recovery timer is cleared.

[0068] In a possible implementation, S3 includes:

[0069] Judge whether the Boolean type of the input flag bit is true;

[0070] If so, update the fault timer to obtain the updated fault update time, and perform a clearing operation on the recovery timer according to the fault update time;

[0071] If not, clear the fault timer according to the time data of the previous fault timer corresponding to the fault timer.

[0072] In the above implementation process, update or clear the fault timer according to the Boolean type of the input flag bit to ensure that the fault can be excluded in time and improve the fault handling efficiency.

[0073] If the current time of the fault timer has not reached the fault reporting time of the fault timer, determine whether the boolean type is true. If the boolean type is true, after incrementing the fault timer by 1, determine whether the current time of the fault timer has reached the fault reporting time. If so, keep the fault timer incremented by 1 unchanged, clear the recovery timer, and set the output data corresponding to the current input flag bit and the next input flag bit to an invalid value. The boolean type of the fault flag bit corresponding to the current input flag bit and the next input flag bit is true. If not, the output data corresponding to the current input flag bit and the next input flag bit is an invalid value. If the boolean type is not true, determine whether the previous fault timer of the fault timer is greater than 0. If so, the output data of the current input flag bit is an invalid value. If not, the output data is the sampled value, and the fault timer is cleared.

[0074] In a possible implementation, the step of clearing the recovery timer according to the fault update time includes:

[0075] Determine whether the fault update time has reached the fault reporting time;

[0076] If so, perform a clearing operation on the recovery timer.

[0077] In the above implementation process, faults can be excluded in a timely manner, the cleared state of the fault timer can be ensured, and it is convenient for the next fault exclusion.

[0078] In a possible implementation, the step of clearing the fault timer according to the time data of the previous fault timer corresponding to the fault timer includes:

[0079] Determine whether the time data is greater than zero;

[0080] If not, perform a clearing operation on the fault timer.

[0081] In the above implementation process, by judging the time data of the two consecutive fault timers, the change situation of the fault timer can be obtained in a timely manner, which can make the clearing operation more accurate.

[0082] When the fault timer has not reached the fault reporting time, first determine whether the time data of the input flag bit of the previous fault timer is greater than zero. If the position of the current input flag bit is greater than 1 and the fault timer of the previous input flag bit is greater than zero, the current output data maintains the invalid value output to prevent the invalid value processing from being overwritten. After the fault timer of the previous input flag bit reaches the fault reporting time, since the fault timer is incremented by 1, the invalid value output is still maintained.

[0083] The fault timer of the previous input flag bit is not greater than zero, determine that the output data corresponding to the fault timer is the sampled value, and perform a clearing operation on the fault timer.

[0084] During the process of recovering from a fault, if the boolean type of the current input flag bit is true, the recovery timer is cleared. If the boolean type of the current input flag bit is not true, the recovery timer is incremented by one. When the recovery timer reaches the recovery reporting time, the faults of the current input flag bit and the next input flag bit are cleared, the fault timer is cleared, and the output data of the current input flag bit and the next input flag bit is the sampled value.

[0085] Further, after the step of obtaining the current time and the fault reporting time of the fault timer of the battery module, it further includes:

[0086] If the current time of the fault timer reaches the fault reporting time of the fault timer, obtain the input flag bit corresponding to the fault timer;

[0087] Obtain the boolean type of the input flag bit;

[0088] Perform a clearing operation on the fault timer according to the boolean type.

[0089] In the above implementation process, according to the boolean type of the input flag bit, the fault timer corresponding to the input flag bit is updated and cleared, completing the detection and processing of the fault timer, improving the fault detection efficiency of the battery module, reducing the error rate of fault detection, and saving labor costs and time costs.

[0090] In a possible implementation, the step of performing a clearing operation on the fault timer according to the boolean type includes:

[0091] Judge whether the boolean type is false;

[0092] If so, perform an update operation on the recovery timer to obtain the updated recovery update time, and perform a clearing operation on the fault timer according to the recovery update time;

[0093] If not, clear the recovery timer.

[0094] In the above implementation process, according to the fault timer, the recovery timer corresponding to the input flag bit is updated and cleared, so that when clearing the fault, it is necessary to add a judgment on the recovery timer, which can reduce errors and make the fault clearing more accurate.

[0095] In a possible implementation, the step of performing a clearing operation on the fault timer according to the update time includes:

[0096] Obtain the recovery reporting time of the recovery timer;

[0097] Judge whether the recovery update time reaches the recovery reporting time;

[0098] If so, perform a clearing operation on the fault timer.

[0099] In the above implementation process, the fault timer is cleared according to the recovery timer, ensuring that the fault timer can simultaneously reduce the fault handling time and improve efficiency based on the recovery reporting time of the recovery timer.

[0100] If the boolean type is not false, the recovery timer is cleared, and the input data of the fault timer is an invalid value; if the boolean type is false, after the recovery timer is incremented by 1, it is determined whether the recovery update time of the recovery timer reaches the recovery reporting time. If it reaches, the output data corresponding to the current input flag bit and the next input flag bit is the sampled value, the boolean type of the fault flag bit corresponding to the current input flag bit and the next input flag bit is false, and the fault timer is cleared. If it does not reach, the output data corresponding to the current input flag bit and the next input flag bit is an invalid value.

[0106] In the above implementation process, if the current time of the fault timer does not reach the reporting time of the fault timer, the input flag bit of the fault timer is also acquired, and the fault timer corresponding to the input flag bit is updated and cleared according to the boolean type of the input flag bit, improving the fault detection efficiency of the battery module.
