In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a flowchart of a method for determining a fault of a battery system according to an embodiment of the present invention. The method may be performed by a fault determination device of a battery system, which may be implemented in the form of hardware and/or software. As shown in fig. 1, the method includes:
as shown in fig. 1, the method of the embodiment may specifically include:
and S110, detecting a detection result generated by each system detection of the battery system if the current state of the battery system is detected to meet the abnormal triggering condition.
The current state may be a voltage state, a temperature state, a current state, a communication state, an insulation resistance state, and a relay state of the battery system. For example, the current state satisfying the preset exception triggering condition may be: the voltage state value is lower than a preset voltage minimum threshold, the voltage state value is higher than a preset voltage maximum threshold, the current state value is higher than a preset current maximum threshold, the current state value is lower than a preset current minimum threshold, CAN bus communication abnormity, low-voltage power supply abnormity, insulation resistance value is lower than a preset resistance value, a high-voltage relay is adhered or normally opened and the like.
When the current state meets the preset abnormal triggering condition, the fault determination process of the battery system can be started, and the detection result generated by each system detection on the battery system after the current moment is detected. For example, the system detection may be a periodic detection for detecting the power battery subsystem and the battery management subsystem in the battery system. For the purpose of describing the power battery subsystem and the battery management subsystem in the battery system, reference may be made to fig. 2.
In fig. 2, a key door signal corresponding to the electric vehicle when the key is placed in different gears and a charging gun signal generated during charging are both sent to a battery system main control unit in the battery management subsystem, and the battery management subsystem further includes a battery cell detection module for acquiring battery cell information in the power battery subsystem, determining information such as battery cell voltage and battery cell temperature based on the battery cell information, and sending the information to the battery system main control unit; the battery management subsystem also comprises a battery voltage detection module which is used for acquiring the battery high-voltage information of the power battery subsystem, determining the total voltage and the total current of the battery pack based on the battery high-voltage information, and sending the total voltage and the total current to the battery system main control unit.
Optionally, before detecting a detection result generated by each system detection performed on the battery system, the method further includes: determining a current abnormal grade corresponding to the battery system based on the current state of the battery system; and determining a fault determination threshold corresponding to the current abnormal grade based on the corresponding relation between the preset abnormal grade and the fault determination threshold.
Specifically, the current abnormality level is used to indicate the degree of abnormality of the current state of the battery system. For example, the higher the level, the higher the degree of abnormality indicating the current state. For example, the current abnormal level of the battery system may be classified into three cases of "first level", "second level", and "third level", the current abnormal level of the CAN bus communication abnormality, the low voltage power supply abnormality, the high voltage relay adhesion or normally open state, and the like may be set to the second level, and for the state having specific values such as the voltage state value, the current state value, the insulation resistance value, and the like, the corresponding current abnormal level may be determined according to the actual value.
In this embodiment, the correspondence relationship between the abnormality level and the failure determination threshold value may be set in advance, and different abnormality levels may correspond to different failure determination threshold values. For example, since the higher the grade is, the more obvious the abnormal phenomenon is, the more serious the possible consequences are; correspondingly, the shorter the time for determining the fault is, so that the emergency can be processed in time, for the three-level abnormity, the set fault determination threshold value is smaller, and the battery system is prevented from being greatly influenced by the emergency fault; and for a one-level abnormality, the set failure determination threshold may be greater than the failure determination threshold corresponding to the three-level to more accurately determine whether the battery system has failed.
In a specific implementation, a fault determination threshold corresponding to the current abnormality level may be determined based on a correspondence between preset abnormality levels and the fault determination threshold, so as to determine whether the battery system is faulty based on the fault determination threshold.
And S120, determining the current abnormal times corresponding to the current system detection based on the first preset counting mode and each detection result.
And counting the abnormal times corresponding to the detection result until the current abnormal times are counted. The first predetermined counting manner may be: if the current detection result detected by the current system is abnormal, determining the current abnormal times in an accumulation calculation mode; and if the current detection result detected by the current system is normal, determining the current abnormal times in an accumulation and subtraction calculation mode.
Optionally, determining the current abnormal times corresponding to the current system detection based on the first preset counting mode and each detection result, including: if the current detection result corresponding to the current system detection is abnormal, determining the sum of the previous abnormal times and a preset first unit numerical value, and determining the sum as the current abnormal times; and if the current detection result corresponding to the current system detection is normal, determining the difference between the previous abnormal times and the first unit numerical value, and determining the difference as the current abnormal times.
The first unit value can be set to 1, and those skilled in the art can set a corresponding first unit value according to an actual application requirement, which is not limited in the embodiment of the present invention. For example, if the previous abnormal time is 5, when the current detection result corresponding to the current system detection is abnormal, the current abnormal time may be determined to be "5+1", that is, 6 times; and when the current detection result corresponding to the current system detection is normal, determining that the current abnormal times are 5-1, namely 4.
And S130, if the current abnormal times reach a predetermined fault determination threshold, determining that the battery system has faults, and performing fault alarm on the battery system.
Specifically, after the current abnormal frequency is determined through a first preset counting mode, the current abnormal frequency is compared with a predetermined fault determination threshold, if the current abnormal frequency is smaller than the fault determination threshold, the detection result detected by the system is continuously detected, and the current abnormal frequency is determined; and if the current abnormal times reach the fault determination threshold, the current state of the battery system is judged to meet the fault condition, the battery system can be determined to have faults, and fault alarm is carried out.
In this embodiment, after determining the current abnormal times corresponding to the current system detection, the method further includes: and if the current abnormal times reach a preset non-fault determination threshold, determining that the battery system has no fault, and stopping detecting the detection result.
Specifically, the non-failure determination threshold may be predetermined, and if the non-failure determination threshold is set to 0, that is, when the current abnormal frequency is 0, it may be determined that the current state of the battery system satisfies the non-failure condition, it may be determined that the battery system is not failed, and the detection result detected by the system does not need to be continuously detected. By setting the non-fault threshold value, whether the battery system has no fault can be determined in time, frequent acquisition of detection results is avoided, and workload for determining the fault of the battery system is reduced.
For a clearer and detailed description of the process of determining whether the battery system is malfunctioning, reference may be made to fig. 3. In fig. 3, when it is detected that the current state of the battery system satisfies the abnormality triggering condition, the abnormality level and the failure determination threshold may be determined, and the current abnormality number is initialized to 1. After entering a fault determination process, judging whether a current detection result detected by a current system is abnormal or not according to each system detection period, if so, adding 1 to the count on the basis of the last abnormal frequency to obtain the current abnormal frequency; if not, on the basis of the last abnormal frequency, counting and subtracting 1 to obtain the current abnormal frequency. Further, after the current abnormal times are determined each time, whether the current abnormal times are equal to the fault determination threshold value or not can be determined; meanwhile, it is determined whether the current abnormality number is equal to 0.
When determining whether the current abnormal times are equal to a fault determination threshold, if the current abnormal times are equal to the fault determination threshold, determining the fault of the battery system, and performing fault prompt; and when the current abnormal times are not equal to the fault determination threshold, continuously detecting the detection result of the system detection in the next period, and repeatedly determining the current abnormal times.
When determining whether the current abnormal times are equal to 0, if the current abnormal times are equal to 0, determining that the battery system has no fault, exiting the fault determination process, and stopping detecting the detection result; if the current abnormal times are not equal to 0, the detection result of the system detection of the next period is continuously detected, and the current abnormal times are determined repeatedly.
According to the technical scheme of the embodiment of the invention, when the current state of the battery system is detected to meet the abnormal triggering condition, the detection result generated by each system detection on the battery system is detected; determining the current abnormal times corresponding to the current system detection based on the first preset counting mode and each detection result; and if the current abnormal times reach a predetermined fault determination threshold value, determining that the battery system has a fault, and performing fault alarm on the battery system. According to the technical scheme of the embodiment of the invention, when the current abnormal times reach the fault determination threshold, the battery system is determined to have faults, the false alarm caused by the possible fluctuation of the system environment of the battery system is solved, and the accuracy and the effectiveness of fault determination are favorably improved.
Fig. 4 is a flowchart of another method for determining a fault of a battery system according to an embodiment of the present invention. The relationship between the present embodiment and the above embodiments is; a process of determining whether the failure is cleared after determining that the battery system has failed is added. The same or corresponding terms as those in the above embodiments are not explained in detail herein. As shown in fig. 4, the method includes:
and S210, detecting a detection result generated by each system detection of the battery system if the current state of the battery system is detected to meet the abnormal triggering condition.
And S220, determining the current abnormal times corresponding to the current system detection based on the first preset counting mode and each detection result.
And S230, if the current abnormal times reach a predetermined fault determination threshold, determining that the battery system has faults, and performing fault alarm on the battery system.
And S240, detecting a detection result generated by each system detection of the battery system if the current state of the battery system is detected to meet the fault clearing condition.
Wherein the fault clearing condition may be that the determined fault of the battery system has disappeared.
In a particular implementation, it may be determined whether the determined fault of the battery system has disappeared for the first time based on the current state. For example, the battery system determines that the bus communication is abnormally failed, and if the detected current state shows that the bus communication of the television system is normal, the current state indicates that the fault clearing condition is met. And when the current state meets the preset fault clearing condition, entering a fault clearing process of the battery system, and detecting a detection result generated by each system detection on the battery system after the current moment.
And S250, determining the current clearing times corresponding to the current system detection based on the second preset counting mode and each detection result.
And counting the clearing times corresponding to the detection result until the current clearing times are counted after the fault clearing process is entered. The second predetermined counting manner may be: if the current detection result of the current system detection is normal, determining the current clearing times in an accumulation calculation mode; and if the current detection result detected by the current system is abnormal, setting the current clearing times as a preset fault value. The preset fault value may be 0, and a person skilled in the art may also determine a specific numerical value of the preset fault value according to an actual application situation, which is not limited in the embodiment of the present invention.
Optionally, determining the current clearing frequency corresponding to the current system detection based on the second preset counting mode and each detection result, including: if the current detection result corresponding to the current system detection is normal, determining the sum of the previous clearing frequency and a preset second unit numerical value, and determining the sum as the current clearing frequency; and if the current detection result corresponding to the current system detection is abnormal, determining the current clearing times as a preset fault value.
The second unit value can be set to 1, and those skilled in the art can set a corresponding second unit value according to an actual application requirement, which is not limited in the embodiment of the present invention. For example, if the previous clearing time is 5, when the current detection result corresponding to the current system detection is normal, it may be determined that the current clearing time is "5+1", which is 6 times; when the current detection result corresponding to the current system detection is abnormal, the current clearing frequency can be determined to be 0.
And S260, if the current clearing times reach a predetermined fault clearing threshold value, determining that the fault of the battery system is cleared, and releasing the alarm of the battery system.
Specifically, after the current clearing times are determined through a second preset counting mode, the current clearing times are compared with a predetermined fault clearing threshold, if the current clearing times are smaller than the fault clearing threshold, the detection result detected by the system is continuously detected, and the current clearing times are determined; if the current clearing times reach the fault clearing threshold, the current state of the battery system meets the fault clearing condition, and the fault clearing of the battery system can be determined.
In this embodiment, the method further includes: and when the current clearing times is a preset fault value, stopping counting the clearing times of the battery system, determining that the battery system is in a fault state, and keeping performing fault alarm on the battery system.
Specifically, when the current abnormal times is a preset fault value, it is indicated that the battery system still has a fault, the fault clearing process can be exited, the clearing times are not counted, and the battery system continues to be subjected to fault alarm to remind a worker to eliminate the fault as soon as possible. According to the embodiment of the invention, when the current detection result is abnormal, the current abnormal frequency is determined to be the preset fault value, so that the fault of the battery system can be eliminated more cautiously, and the safety of the battery system is improved.
To more clearly and in detail describe the process of determining whether the fault of the battery system is cleared, reference is made to fig. 5. In fig. 5, when it is detected that the current state of the battery system satisfies the fault clearing condition, the current clearing number is initialized to 1. After entering a fault clearing flow, judging whether a current detection result detected by a current system is normal or not according to each system detection period, and if so, adding 1 to the count on the basis of the last clearing frequency to obtain the current clearing frequency; if not, determining the current clearing times to be 0. Further, after the current clearing times are determined each time, whether the current clearing times are equal to the fault clearing threshold value or not can be determined; meanwhile, it is determined whether the current clearing number is 0.
Determining whether the current clearing times are equal to a fault clearing threshold value, and if the current clearing times are equal to the fault clearing threshold value, determining that the fault of the battery system is cleared; and when the current clearing times are not equal to the fault clearing threshold, continuously detecting the detection result of the system detection in the next period, and repeatedly determining the current clearing times.
When the current clearing frequency is determined to be 0 or not, if the current clearing frequency is equal to 0, determining that the battery system still has a fault, quitting the fault clearing process, and stopping detecting the detection result; if the current clearing times are not equal to 0, the detection result of the system detection of the next period is continuously detected, and the current clearing times are repeatedly determined.
According to the technical scheme of the embodiment of the invention, when the current state of the battery system is detected to meet the fault clearing condition, the detection result generated by each system detection on the battery system is detected; determining the current clearing times corresponding to the current system detection based on a second preset counting mode and each detection result; and if the current clearing times reach a predetermined fault clearing threshold value, determining that the fault occurring in the battery system is cleared, and removing the alarm of the battery system. The method for determining whether the battery system fault is cleared is provided, so that the accuracy of determining whether the battery system has the fault is improved, and the fault alarm can be cancelled for the repaired battery system in time.
