Among these, safety monitoring is a prerequisite for fault handling and alarms; only by detecting battery abnormalities can subsequent fault handling and alarms be implemented.

[0027] Example 1

[0028] Figure 1 This is a flowchart illustrating a battery monitoring mechanism verification method provided in an embodiment of the present invention. This embodiment is applicable to situations where various wake-up methods of a power battery management system are functionally verified. This method can be executed by a battery monitoring mechanism verification device, which can be implemented in hardware and / or software. This battery monitoring mechanism verification device can be configured in an electronic device that has a battery monitoring mechanism verification method. Figure 1 As shown, the method includes:

[0029] S110. When the vehicle is in a wake-up state, obtain the reference battery data after the vehicle is woken up.

[0030] The battery monitoring wake-up mechanism of this application is a mechanism that detects the battery status through reverse wake-up and / or timed wake-up when the battery status may be abnormal. The wake-up method is the vehicle wake-up method, such as wake-up through an external pressure sensor, clock chip and analog front end. In order to avoid false wake-up, different wake-up methods must be verified after the vehicle is in the wake-up state to ensure that the wake-up source is correct, thereby ensuring that the battery monitoring is correct.

[0031] Among them, reference battery data refers to the battery data collected after the vehicle is woken up, and the battery data is analyzed to accurately determine the valid data that can represent the battery data obtained after waking up.

[0032] Optionally, before the vehicle is in a wake-up state, it is necessary to accurately determine how to wake up the vehicle, as follows:

[0033] Because the vehicle is in a dormant state before being woken up, it is necessary to obtain the vehicle's current battery data and preset wake-up parameters when the vehicle is in a dormant state. Then, the current battery data and preset wake-up parameters are compared and analyzed to accurately determine whether to wake up the vehicle. The battery data includes at least the battery pack pressure value, battery temperature, battery voltage value, and battery dormant time. The preset wake-up parameters include the wake-up pressure change threshold, the wake-up pressure change rate threshold, the timed wake-up cycle, the wake-up voltage threshold, and the wake-up temperature threshold.

[0034] The specific comparison results fall into the following three categories:

[0035] The first method: If the first parameter is greater than the wake-up pressure change threshold and / or the second parameter is greater than the wake-up pressure change rate threshold, the vehicle is woken up in reverse by an external pressure sensor; wherein, the first parameter is the difference in the pressure value inside the battery pack within a preset time interval when the vehicle is in a dormant state, and the second parameter is the rate of change of the pressure value inside the battery pack within a preset time interval when the vehicle is in a dormant state.

[0036] The second method: If the current battery sleep time is greater than the timed wake-up cycle, the vehicle is woken up by the clock chip; wherein, the current battery sleep time is the time interval from when the battery enters sleep mode to the current moment;

[0037] The third method: If the current battery temperature is greater than the wake-up temperature threshold and / or the current battery voltage is less than the wake-up voltage threshold, then the vehicle is woken up by simulating the front end.

[0038] This technical solution compares the current battery data in a dormant state with preset wake-up parameters to accurately determine whether the vehicle has been woken up, so that the accuracy of the reference battery data obtained by the vehicle can be accurately determined in the future.

[0039] S120. Determine the wake-up source of the vehicle; wherein the wake-up source includes an external pressure sensor, an analog front end, and a clock chip.

[0040] Specifically, after the vehicle is woken up, the hardware configuration in the vehicle will promptly identify the wake-up source corresponding to the vehicle and upload the identified wake-up source so that the wake-up source can be verified later.

[0041] S130. Based on the reference battery data, perform a wake-up verification on the wake-up source to determine whether the wake-up source is abnormal.

[0042] Specifically, after obtaining reference battery data and the wake-up source, preset wake-up parameters are also obtained. Based on the reference battery data and preset wake-up parameters, the wake-up source is verified to accurately determine whether there is an anomaly in the wake-up source, and to remind the driver to perform maintenance or issue a warning. In addition, when there is an anomaly in the wake-up source, the battery data can be uploaded to the cloud and then redundancy verification can be performed in the cloud. If the verification result is consistent with that of the vehicle, it further indicates that an alarm needs to be issued to remind the driver to perform vehicle maintenance.

[0043] The technical solution of this invention involves acquiring reference battery data after the vehicle is woken up when it is in a wake-up state; then determining the wake-up source of the vehicle; wherein the wake-up source includes an external pressure sensor, an analog front-end, and a clock chip; finally, based on the reference battery data, performing a wake-up verification on the wake-up source to determine whether the wake-up source has malfunctioned. This technical solution achieves accurate verification of the wake-up source by analyzing the reference battery data, thus mitigating the risk of false wake-ups due to problems with any of the external pressure sensor, clock chip, or analog front-end, thereby preventing false battery fault reports.

[0044] Example 2

[0045] Figure 2 This is a flowchart of a verification method for a battery monitoring mechanism provided in an embodiment of the present invention. This embodiment provides a detailed description of S130 in the above embodiment. Figure 2 As shown, the method includes:

[0046] S210. When the vehicle is in a wake-up state, obtain the reference battery data after the vehicle is woken up, and at the same time determine the wake-up source of the vehicle.

[0047] S220. If the wake-up source is an external pressure sensor, the reference battery data is the wake-up pressure value. Perform a wake-up verification on the wake-up source to determine whether the wake-up source is abnormal.

[0048] Specifically, the third parameter of the vehicle is obtained; the third parameter is the battery pressure value at a preset time before the vehicle enters the hibernation time. The time interval between the preset time and the hibernation time is less than the preset time. That is, the obtained value is the battery pressure value when the vehicle was about to enter hibernation at the last time it was awake, relative to the current awake state.

[0049] If the difference between the fourth parameter P3 and the wake-up pressure change threshold P1 is less than the pressure sampling error ΔP of the external pressure sensor (i.e., P3-P1<ΔP) and the external pressure sensor is fault-free, then the verification pressure result is abnormal, and the first verification result abnormality flag is set to 1; where the fourth parameter is the difference between the third parameter and the wake-up pressure value.

[0050] When the first verification result anomaly flag is set to 1, the count of the first verification result anomaly flag being set to 1 is performed. When the count reaches a first preset value, it indicates that there may be a problem with the external pressure sensor, and the external pressure sensor reverse wake-up function is disabled. If the first verification result anomaly flag is not triggered and the external pressure sensor is faulty, the external pressure sensor reverse wake-up function is disabled. The first preset value can be set according to the actual vehicle conditions, such as 3-5 times. If the first verification result anomaly flag is not triggered and the external pressure sensor is not faulty, the vehicle operates normally.

[0051] S230. If the wake-up source is an analog front end, the reference battery data are the wake-up voltage value and the wake-up temperature value. Perform a wake-up verification on the wake-up source to determine whether the wake-up source is abnormal.

[0052] Specifically, if the wake-up source is an analog front-end, reference battery data including wake-up voltage and wake-up temperature values ​​is obtained, along with preset wake-up parameters including wake-up voltage and wake-up temperature thresholds. The reference battery data is compared with the preset wake-up parameters to determine the status of the second verification result anomaly flag. Specifically, there are at least three possible scenarios:

[0053] First: If the wake-up voltage value V2 is greater than the wake-up voltage threshold V1, and the fifth parameter |V2-V1| is greater than the voltage sampling error ΔV of the analog front-end, and the analog front-end is fault-free, then the verification voltage result is abnormal, and the second verification result abnormality flag is set to 1; where the fifth parameter is the absolute value of the difference between the wake-up voltage value and the wake-up voltage threshold.

[0054] Second: If the wake-up temperature value T2 is less than the wake-up temperature threshold T1, and the sixth parameter |T2-T1| is greater than the temperature sampling error ΔT of the analog front-end, and the analog front-end is fault-free, then the temperature verification result is abnormal, and the second verification result abnormality flag is set to 2; where the sixth parameter is the absolute value of the difference between the wake-up temperature value and the wake-up temperature threshold.

[0055] Third: If the wake-up voltage value V2 is greater than the wake-up voltage threshold V1, and the fifth parameter |V2-V1| is greater than the voltage sampling error ΔV of the analog front end, and the wake-up temperature value T2 is less than the wake-up temperature threshold T1, and the sixth parameter |T2-T1| is greater than the temperature sampling error ΔT of the analog front end, and the analog front end is fault-free, then the verification voltage and temperature results are abnormal, and the second verification result abnormality flag is set to 3.

[0056] When any of the above three situations occur, it indicates that the second verification result anomaly flag has been triggered. The trigger count for this flag needs to be kept. When the count reaches a second preset value, it indicates a potential problem with the simulation front-end, and the simulation front-end reverse wake-up function is disabled. The trigger is achieved by setting the second verification result anomaly flag to 1, 2, or 3. The second preset value can be set according to the actual vehicle conditions, such as 3-5 times. If the second verification result anomaly flag is not triggered and the simulation front-end is faulty, the simulation front-end reverse wake-up function is disabled. If the second verification result anomaly flag is not triggered and the simulation front-end is fault-free, the vehicle operates normally.

[0057] S240. If the wake-up source is a clock chip, the wake-up time interval is referenced from the battery data. A wake-up verification is performed on the wake-up source to determine whether an abnormality has occurred.

[0058] Specifically, if the wake-up source is a clock chip, the wake-up time interval and the current wake-up period are obtained. The current wake-up period is the timed wake-up period when the vehicle is determined to be in the current wake-up state. The status of the third verification result abnormality flag is further determined based on the wake-up time interval and the current wake-up period, specifically in at least the following three cases:

[0059] First: If the wake-up time interval t0 is greater than the current wake-up cycle t1, and the seventh parameter |t0-t1| is greater than the wake-up cycle control error Δt of the clock chip, and the clock chip is fault-free, then the verification time information result is abnormal, and the third verification result abnormality flag is set to 1; where the wake-up time interval is the time interval between the time when the vehicle enters sleep mode and the time when it is woken up again, and the seventh parameter is the absolute value of the difference between the wake-up time interval and the current wake-up cycle.

[0060] Second: If the wake-up time interval t0 is less than the current wake-up cycle t1, and the seventh parameter |t0-t1| is greater than the wake-up cycle control error Δt of the clock chip, and the clock chip is fault-free, then the verification time information result is abnormal, and the third verification result abnormality flag is set to 2.

[0061] Third: If the seventh parameter |t0-t1| is greater than the wake-up cycle control error Δt of the preset multiple n, and the clock chip is fault-free, then the verification time information result is abnormal, and the abnormal flag of the third verification result is set to 3. The preset multiple n is set according to the specific situation of the vehicle clock chip, such as 5-10.

[0062] When the third verification result shows the above-mentioned abnormality, the specific corresponding operations are as follows:

[0063] When the third verification result error flag is set to 1, it indicates that the clock chip's time period is a bit long and needs to be shortened to ensure accurate battery monitoring. Therefore, the timed wake-up period is adjusted to the first wake-up period value. The first wake-up period value is the difference between the current wake-up period and the wake-up period control error, i.e., the first wake-up period value is t1-Δt.

[0064] When the third verification result error flag is set to 2, it indicates that the clock chip's large time period is a bit short and needs to be extended to ensure accurate battery monitoring. Therefore, the timed wake-up period is adjusted to the second wake-up period value. The second wake-up period value is the sum of the current wake-up period and the wake-up period control error, that is, the second wake-up period value is t1+Δt.

[0065] When the third verification result abnormality flag is set to 3, it indicates that there may be a problem with the clock chip. Therefore, the third verification result abnormality flag is counted. When the number of times is set to 3, it indicates that there is a problem with the clock chip, and the clock chip timed wake-up function is turned off. The third preset value can be set according to the actual vehicle conditions, such as 3-5 times.

[0066] When the third verification result abnormality flag is set to 1 or 2, and there is a fault in the simulated front end, it indicates that the wake-up cycle needs to be shortened to ensure effective monitoring of the battery and avoid the inability to monitor the battery in a timely manner due to the lack of a wake-up mode. Therefore, the timed wake-up cycle is adjusted to the third wake-up cycle value t1 / m, where the third wake-up cycle value is the ratio of the current wake-up cycle to the preset value m; where m is generally taken as 1.5-5.

[0067] If the third verification result error flag is not triggered and the clock chip is faulty, then the clock chip's timed wake-up function is disabled.

[0068] S250. If the wake-up source includes at least two of the following: an external pressure sensor, an analog front-end, and a clock chip, then a wake-up verification is performed on the wake-up source to determine whether the wake-up source is abnormal.

[0069] Specifically, there may be two or three wake-up sources. Therefore, when several wake-up sources are abnormal, the battery data needs to be uploaded to the cloud for redundancy verification to further determine whether there are any abnormalities in the wake-up sources or other problems with the vehicle, so as to provide timely warnings and avoid false wake-ups of the battery due to problems with the wake-up sources. This also ensures that the vehicle can be maintained in a timely manner, thereby preventing problems from occurring during vehicle operation.

[0070] Optionally, there are at least the following situations for performing wake-up verification on the wake-up source:

[0071] First: When the third verification result abnormality flag is set to 3, and the first verification result abnormality flag and the second verification result abnormality flag are triggered simultaneously, an abnormality signal will be sent to the cloud, and the cloud will perform redundant verification; whereby, redundant verification means that the verification method is consistent with that of the vehicle end.

[0072] Second: When the third verification result abnormality flag is set to 1 or 2, and the first verification result abnormality flag and the second verification result abnormality flag are triggered at the same time, the current battery data is uploaded. After the first preset time, the vehicle terminal controls the vehicle to go into normal sleep mode, and the cloud performs redundancy verification.

[0073] Third: When the third verification result abnormality flag is set to 1 or 2, and the first verification result abnormality flag is triggered but the second verification result abnormality flag is not triggered, and the current battery data is abnormal, then the vehicle terminal data is uploaded. After the second preset time, the vehicle terminal controls the vehicle to go into normal sleep mode, and the cloud performs redundancy verification. The first preset time and the second preset time are determined according to specific circumstances, and no specific restrictions are made here.

[0074] Fourth: When the third verification result abnormality flag is set to 1 or 2, the first verification result abnormality flag is triggered and the second verification result abnormality flag is not triggered, and the current battery data is normal, the vehicle terminal controls the vehicle to go into normal sleep mode.

[0075] The cloud-based redundancy check works as follows: if the cloud-based check result matches the vehicle-side check result, the user is prompted to repair the vehicle; if the cloud-based check result does not match the vehicle-side check result, the number of times the discrepancy occurs is recorded in the cloud. When the number of discrepancies reaches a fourth preset value, the user is prompted to repair the vehicle. The fourth preset value is generally set to 3-5 times.

[0076] The technical solution of this invention, when the vehicle is in a wake-up state, acquires reference battery data and preset wake-up parameters after the vehicle is woken up, and determines the wake-up source of the vehicle. Further, the wake-up source is verified based on the reference battery data and preset wake-up parameters to accurately determine whether the wake-up source is abnormal. This solves the risk of false wake-up caused by any problem with the external pressure sensor, clock chip, and analog front end, thereby causing the risk of false battery fault reports.

[0089] If the difference between the fourth parameter and the wake-up pressure change threshold is less than the pressure sampling error of the external pressure sensor, and the external pressure sensor is fault-free, then the verification pressure result is abnormal, and the first verification result abnormality flag is set to 1; wherein, the fourth parameter is the difference between the third parameter and the wake-up pressure value;

[0090] When the first verification result abnormality flag is set to 1, the count of the first verification result abnormality flag being set to 1 is performed. When the count reaches the first preset value, the external pressure sensor reverse wake-up function is turned off.

[0091] If the first verification result error flag is not triggered and the external pressure sensor is faulty, then the external pressure sensor reverse wake-up function is disabled.

[0092] Optionally, if the wake-up source is an analog front-end, and the reference battery data are the wake-up voltage value and the wake-up temperature value, the verification module includes a second verification unit, specifically used for:

[0093] If the wake-up voltage value is greater than the wake-up voltage threshold, and the fifth parameter is greater than the voltage sampling error of the analog front-end, and the analog front-end is fault-free, then the verification voltage result is abnormal, and the second verification result abnormality flag is set to 1; wherein, the fifth parameter is the absolute value of the difference between the wake-up voltage value and the wake-up voltage threshold;

[0094] If the wake-up temperature value is less than the wake-up temperature threshold, and the sixth parameter is greater than the temperature sampling error of the analog front-end, and the analog front-end is fault-free, then the temperature verification result is abnormal, and the second verification result abnormality flag is set to 2; wherein, the sixth parameter is the absolute value of the difference between the wake-up temperature value and the wake-up temperature threshold;

[0096] When the second verification result abnormality flag is triggered, the triggering of the second verification result abnormality flag is counted. When the number of times reaches the second preset value, the simulated front-end reverse wake-up function is turned off; wherein, the triggering is to set the second verification result abnormality flag to 1, 2 or 3.

[0097] If the second verification result error flag is not triggered and the simulated front-end is faulty, then the simulated front-end reverse wake-up function is disabled.

[0098] Optionally, if the wake-up source is a clock chip and the reference battery data is a wake-up time interval, the verification module includes a third verification unit, specifically used for:

[0099] Obtain the current wake-up cycle, which is the timed wake-up cycle when the vehicle is determined to be in the current wake-up state;

[0100] If the wake-up time interval is greater than the current wake-up cycle, and the seventh parameter is greater than the wake-up cycle control error of the clock chip, and the clock chip is fault-free, then the verification time information result is abnormal, and the third verification result abnormality flag is set to 1; wherein, the wake-up time interval is the time interval between the time when the vehicle enters sleep mode and the time when it is woken up again, and the seventh parameter is the absolute value of the difference between the wake-up time interval and the current wake-up cycle.
