Example 1:

FIG. 1 shows the implementation process of a battery charge and discharge data storage method provided by an embodiment of the present invention, and the process is described in detail as follows:

In S101, the charge and discharge data generated by the battery system within a first preset time period are acquired, and according to the charge and discharge data, it is determined whether the charge and discharge data satisfies one charge/discharge cycle of the battery system.

In S102, when it is determined that the charge/discharge data satisfies one charge/discharge cycle of the battery system, it is detected whether the charge/discharge data within the charge/discharge cycle meets a preset charge/discharge condition, and if it is within the charge/discharge cycle If the charge/discharge data in the charge/discharge cycle satisfies the preset charge/discharge condition, then the charge/discharge data of the battery system is stored according to the charge/discharge data satisfying the preset charge/discharge condition.

In this embodiment, battery data is classified into statistical information, event status information and detailed analog information. Among them, statistical information is information that is classified into statistics and reflects the overall situation of the system, such as power generation, income, total power, etc. The statistical information can be collected and saved according to a certain collection frequency. The event state quantity information can very intuitively reflect the overall running state of the current system, and this type of information needs to be saved immediately at the moment of the occurrence and cancellation of the event. The data volume of detailed analog information is large, and corresponding storage strategies need to be formulated to optimize the business process of information storage. The detailed analog data in this application is the charge and discharge data. The charge and discharge data of the battery is an important basis for studying the physical characteristics of the battery and improving the performance and life of the battery. It is the representative data in the analysis of the battery performance data. important value.

In this embodiment, the charge and discharge data generated by the battery system are collected at preset time intervals within a first preset time period, wherein the first preset time period may be 36 hours, that is, the battery charge and discharge data within 36 hours are cached Discharge data, the preset time interval can be 30 seconds.

In this embodiment, the collected charge and discharge data are buffered according to the data recording time, and the data recording time is the collection time of the charge and discharge data.

In this embodiment, whether there is a complete charge/discharge cycle in the charge-discharge data is searched according to a preset cycle, the preset cycle may be 12 hours, the charge/discharge cycle search process is performed every 12 hours, and the search process finds 12 Whether there is a charge/discharge cycle within an hour, if there is no charge/discharge cycle, no data in the preset cycle will be stored. If there is a charge/discharge cycle, check whether all the charge/discharge data in the charge/discharge cycle meet the preset charge/discharge condition, and store the charge/discharge data of the battery system according to the charge/discharge data of the preset charge/discharge condition.

It can be seen from the above embodiments that the embodiment of the present invention acquires the charge and discharge data generated by the battery system within the first preset time period, and determines whether the charge and discharge data satisfies a charge/discharge requirement of the battery system according to the charge and discharge data. a discharge cycle; when it is determined that the charge and discharge data satisfies a charge/discharge cycle of the battery system, detect whether the charge and discharge data within the charge/discharge cycle meet a preset charge/discharge condition, if the charge/discharge data is in the charge/discharge cycle The charge/discharge data in the /discharge cycle satisfies the preset charge/discharge condition, and then the charge/discharge data of the battery system is stored according to the charge/discharge data that meets the preset charge/discharge condition. Since the data in the charging/discharging cycle is an important basis for studying the physical characteristics of the battery, the embodiment of the present invention only stores the charging/discharging data of the charging/discharging cycle that meets the preset charging/discharging conditions, thereby reducing the battery data that needs to be stored It can save system space and improve the overall utilization of battery data.

In an embodiment of the present invention, the specific implementation process of S101 in FIG. 1 includes:

When there is charge and discharge data smaller than the preset lower limit value of remaining power and at the same time greater than or equal to the preset upper limit value of remaining power in the charge and discharge data, it is determined that the charge and discharge data satisfies one charge of the battery system /discharge cycle.

As shown in FIG. 2, in an embodiment of the present invention, the specific implementation process of the above S101 further includes:

In S201, the charge and discharge data are arranged in chronological order,

In S202, if there is at least one charge and discharge data greater than or equal to the preset upper limit value of remaining power between any two charge and discharge data less than or equal to the preset lower limit value of remaining power, determine that the any two are less than or equal to the preset upper limit value of remaining power. There is charge and discharge data satisfying one charge/discharge cycle of the battery system between the charge and discharge data of the preset remaining power lower limit value; or

In S203, if there is at least one charge and discharge data less than or equal to the preset lower limit of remaining power between any two charge and discharge data greater than or equal to the preset upper limit of remaining power, determine that the any two are greater than or equal to the preset lower limit of remaining power or between the charge and discharge data equal to the preset upper limit value of remaining power, there is charge and discharge data that satisfies one charge/discharge cycle of the battery system.

In this embodiment, the charge and discharge data may be the remaining power of the battery system, and the charge and discharge data that is larger than the preset upper limit of the remaining power in the charge and discharge data is selected as the upper limit data, and the charge and discharge data that is less than the lower limit of the remaining power are selected as the upper limit data. The charge and discharge data are used as the lower limit data. Taking a specific application scenario as an example, the preset upper limit of the remaining power can be 95%, and the lower limit of the remaining power can be 5%. Charge and discharge data with a value greater than 95% are used as upper limit data.

In this embodiment, each charge and discharge data corresponds to a data recording time, and the data recording time is the time for collecting the charge and discharge data. Sort all charge and discharge data by data logging time. Obtain the charge and discharge data sequence, and find out whether there is upper limit data between the two lower limit data in the charge and discharge data sequence. There are charge/discharge cycles between the lower limit data.

In this embodiment, the method for finding the charging/discharging cycle may also be: finding whether there is lower limit data between two upper limit data in the charge and discharge data sequence, and if there is lower limit data, it indicates the battery system within the preset time period If there is a discharge-charge process, it can also be determined that there is a charge/discharge cycle between the two upper limit data.

It can be seen from the above embodiments that the above method can effectively detect whether there is a charge/discharge cycle in the charge/discharge data in the first preset time period, and store the charge/discharge data in the charge/discharge cycle, thereby improving the utilization of the stored data rate and reduce system space.

As shown in FIG. 3, in an embodiment of the present invention, FIG. 3 shows a specific implementation process of S102 in FIG. 1, and the process is described in detail as follows:

In S301, the charge and discharge data are arranged in time sequence.

In S302, compare the charge and discharge data at the current time with the charge and discharge data at the previous time, and when the charge and discharge data at the current time is greater than the charge and discharge data at the previous time, use the charge and discharge data at the current time as valid charge and discharge data .

In S303, it is determined whether the charge and discharge data at the current moment is greater than or equal to a preset upper limit value of remaining power.

In S304, if the charge and discharge data at the current moment is less than the preset remaining power upper limit, the charge and discharge data at the current moment are used as the charge and discharge data at the previous moment, and the charge and discharge data at the next moment are used as the charge and discharge data at the current moment. discharge data, and perform the step of comparing the charge and discharge data at the current moment with the charge and discharge data at the previous moment; if the charge and discharge data at the current moment is greater than or equal to the preset upper limit of the remaining power, the The data is used for charging and discharging data storage of the battery system.

In this embodiment, the charge/discharge cycle may include a charge cycle, and the preset charge/discharge conditions include preset charge conditions. The first lower limit data in the charging cycle is used as the charging starting point data, and the first upper limit data after the charging starting point data is used as the charging end point data in the charging cycle, so as to obtain an initial charging cycle, and then charge the charging in the initial charging cycle. Discharge data for further screening.

In this embodiment, since the remaining power of the battery system fluctuates, in order to better obtain the real charging cycle, the charging and discharging data in the charging cycle are compared in pairs, and the charging starting point data is used as the current data. The data is compared with the charge and discharge data at the previous moment, and the charge and discharge data at the current moment is compared with the charge and discharge data at the previous moment. When the charge and discharge data at the current moment is greater than the charge and discharge data at the previous moment, the current moment The charge and discharge data of , as valid charge and discharge data.

If the charge and discharge data at the current moment is greater than the charge and discharge data at the previous moment, it is determined whether the charge and discharge data at the current moment is greater than or equal to the upper limit of the preset remaining power; if the charge and discharge data at the current moment is greater than or equal to the preset remaining power The upper limit value indicates that the charging is completed, and the charging and discharging storage of the battery system can be performed according to all valid charging and discharging data.

If the charge and discharge data at the current moment is greater than or equal to the preset upper limit of remaining power and less than the preset upper limit of remaining power, it means that the charge and discharge data conforms to the charging trend, and the charge and discharge data are still in the process of charging, and the charge and discharge data at the current moment are repeated. Step with the charge and discharge data at the previous moment until the updated charge and discharge data at the current moment is greater than or equal to the preset upper limit of the remaining power.

As shown in FIG. 4, in an embodiment of the present invention, FIG. 4 shows a specific implementation process of S102 in FIG. 1, and the process is described in detail as follows:

In S401, when the charge and discharge data at the current moment is less than or equal to the charge and discharge data at the previous moment, it is determined whether the charge and discharge data at the current moment is less than or equal to a preset lower limit of remaining power.

In S402, if the charge and discharge data at the current moment is less than or equal to the preset lower limit value of remaining power, the charge and discharge data at the current moment is taken as the first valid charge and discharge data in the charging cycle, and the comparison of the current charge and discharge data is performed. The procedure of charging and discharging data at the time and the charging and discharging data at the previous time.

In S403, if the charge and discharge data at the current moment is greater than the preset lower limit value of the remaining power, it is detected whether the charge and discharge data at the current moment satisfies the preset fluctuation condition.

In S404, when the charge and discharge data at the current moment satisfies the preset fluctuation condition, the charge and discharge data at the current moment is used as valid charge and discharge data.

In S405, when the charge and discharge data at the current moment does not meet the preset fluctuation condition, it is detected whether there is charge and discharge data less than or equal to the preset lower limit value of remaining power after the charge and discharge data at the current moment, if there is charge and discharge data less than or equal to the preset lower limit value of remaining power Set the charge and discharge data of the lower limit of the remaining power, then use the charge and discharge data as the first valid charge and discharge data in the charging cycle, if there is no charge and discharge data less than or equal to the preset lower limit of the remaining power, then determine The charge and discharge data in the charge cycle do not meet the preset charge conditions.

In this embodiment, during the charging cycle, if the charge and discharge data at the current moment is less than or equal to the charge and discharge data at the previous moment, it is determined whether the charge and discharge data at the current moment is less than or equal to the preset remaining power lower limit.

If the charge and discharge data at the current moment is less than or equal to the preset lower limit of remaining power, it means that the remaining power of the battery fluctuates and fluctuates below the preset lower limit of remaining power. At this time, the charge and discharge data at the current moment can be updated. As the first valid charge and discharge data of the charging cycle, the first valid charge and discharge data after the update is taken as the starting point to restart the detection process of the charge and discharge data.

If the charge and discharge data at the current moment is greater than the lower limit of the preset remaining capacity, it means that the remaining capacity of the battery fluctuates. In order to obtain better battery charge and discharge data, it is necessary to check again whether the charge and discharge data at the current moment meets the preset fluctuation. If the preset fluctuation conditions are met, it proves that although the charge and discharge data fluctuates, the battery charge and discharge data fluctuates little, and the entire charging process can be better displayed. Therefore, the charge and discharge data at the current moment can still be obtained as a valid charge. Discharge data, use the charge and discharge data of the current time as the charge and discharge data of the previous time, use the charge and discharge data of the next time as the charge and discharge data of the current time, and repeat the charge and discharge of the charge and discharge data of the current time at the previous time Data comparison steps.

It can be seen from the above embodiments that the entire charging process of the battery system is represented by the effective stored data, each stored effective stored data can be effectively used, and the overall utilization rate of the effective stored data can be improved.

As shown in FIG. 5, in an embodiment of the present invention, FIG. 5 shows a specific implementation process of S403 in FIG. 4, and the process is described in detail as follows:

In S501, it is detected whether the charge and discharge data at the current moment satisfies a preset single fluctuation condition.

In S502, if the charge and discharge data at the current moment satisfies the preset single fluctuation condition, it is determined that the charge and discharge data at the current moment meets the preset fluctuation condition.

In S503, if the charge and discharge data at the current moment does not meet the preset single fluctuation condition, then check whether the charge and discharge data at the current moment meets the preset cumulative fluctuation condition, and when the charge and discharge data at the current moment meets the preset cumulative fluctuation condition , it is determined that the charge and discharge data at the current moment satisfies the preset fluctuation condition; when the charge and discharge data at the current moment does not meet the preset cumulative fluctuation condition, it is determined that the charge and discharge data at the current moment does not meet the preset fluctuation condition.

In this embodiment, the preset fluctuation conditions include single fluctuation conditions and cumulative fluctuation conditions.

In this embodiment, if the charge and discharge data at the current moment is greater than the preset lower limit value of the remaining power, it means that the battery system fluctuates during the charging process, and it is judged whether the charge and discharge data at the current moment satisfies the single fluctuation condition. The fluctuation range can be no more than 2%. The fluctuation range of the single fluctuation condition can be the difference between the charge and discharge data at the current moment and the charge and discharge data at the previous moment. When the charge and discharge data at the current moment satisfies the single fluctuation condition, check whether the charge and discharge data at the current moment meet the requirements. The cumulative fluctuation condition, the cumulative fluctuation condition can be that the fluctuation range is not more than 5%, and the cumulative number of cumulative fluctuation conditions can be 2, 3 or other cumulative times. When the cumulative number of times is 2, the cumulative fluctuation range is the difference between the charge and discharge data at the current moment and the charge and discharge data at the previous moment. The fluctuation range of the charge and discharge data is not large, and the charge and discharge data at the current moment can be used as the effective charge and discharge data.

When the charge and discharge data at the current moment does not meet the single fluctuation condition, it means that the remaining power of the battery system fluctuates greatly. At this time, check whether there is lower limit data after the charge and discharge data at the current moment. If there is a lower limit data, it means that the battery The remaining power of the system fluctuates below the preset lower limit of remaining power. In this case, it is necessary to update the first valid stored power data of the charging cycle to the first lower limit data after the current moment, and from the updated first data. A valid storage of electrical data begins, restarting the entire detection process.

When the lower limit data is not found after the charge and discharge data at the current moment, it means that the remaining power of the charging cycle fluctuates greatly, and the charge and discharge data of the charging cycle cannot well reflect the complete charging process of the battery. Therefore, it is possible to directly Discard all charge and discharge data for this charge cycle.

When the charge and discharge data at the current moment satisfies the single fluctuation condition but not the cumulative fluctuation condition, similarly, it is necessary to find out whether there is lower limit data after the charge and discharge data at the current moment. Below the lower limit of the remaining power, in this case, the first valid data of the charging cycle needs to be updated to the first lower limit data after the current charge and discharge data, and the updated first valid charge and discharge The data starts, and the entire detection process is restarted.

When the lower limit data is not found after the charging and discharging data at the current moment, it means that the remaining power of the charging cycle fluctuates greatly, and the initial data of the charging cycle cannot well reflect the complete charging process of the battery. Therefore, it can be directly discarded. All initial data for this charge cycle.

As shown in FIG. 6, in an embodiment of the present invention, FIG. 6 shows a specific implementation process of S102 in FIG. 1, and the process is described in detail as follows:

In S601, the charge and discharge data are arranged in time sequence.

In S602, compare the charge and discharge data at the current time with the charge and discharge data at the previous time, and when the charge and discharge data at the current time is smaller than the charge and discharge data at the previous time, use the charge and discharge data at the current time as valid charge and discharge data .

In S603, it is determined whether the charge and discharge data at the current moment is less than or equal to a preset lower limit value of remaining power.

In S604, if the charge and discharge data at the current moment is greater than the preset lower limit value of remaining power, the charge and discharge data at the current moment is used as the charge and discharge data at the previous moment, and the charge and discharge data at the next moment is regarded as the charge and discharge data at the current moment. discharge data, and perform the step of comparing the charge and discharge data at the current moment with the charge and discharge data at the previous moment; The data is used for charging and discharging data storage of the battery system.

In this embodiment, the charge/discharge cycle further includes a discharge cycle, and the preset charge/discharge condition further includes a preset discharge condition. In the same way as the above-mentioned method for obtaining valid charge and discharge data of a charge cycle, the valid charge and discharge data of a discharge cycle is obtained according to a preset discharge condition.

As shown in FIG. 7, in an embodiment of the present invention, FIG. 7 shows a specific implementation process of S102 in FIG. 1, and the process is described in detail as follows:

In S701, when the charge-discharge data at the current moment is greater than or equal to the charge-discharge data at the previous moment, determine whether the charge-discharge data at the current moment is greater than or equal to a preset upper limit of the remaining power;

In S702, if the charge and discharge data at the current moment is greater than or equal to the preset upper limit of remaining power, the charge and discharge data at the current moment is taken as the first valid charge and discharge data in the discharge cycle, and the comparison of the current charge and discharge data is performed. Steps of charging and discharging data at the moment and charging and discharging data at the previous moment;

In S703, if the charge and discharge data at the current moment is less than the preset upper limit value of the remaining power, it is detected whether the charge and discharge data at the current moment satisfies the preset fluctuation condition;

In S704, when the charge and discharge data at the current moment satisfies the preset fluctuation condition, the charge and discharge data at the current moment is used as valid charge and discharge data;

When the charge and discharge data at the current moment does not meet the preset fluctuation condition, check whether there is charge and discharge data greater than or equal to the preset upper limit of remaining power after the charge and discharge data at the current moment. If there is no charge and discharge data that is greater than or equal to the preset upper limit of remaining power, it is determined that the charge and discharge data in the discharge cycle is the first valid charge and discharge data in the discharge cycle. The charge and discharge data do not meet the preset discharge conditions.

As shown in FIG. 8, in an embodiment of the present invention, FIG. 8 shows a specific implementation process of S703 in FIG. 7, and the process is described in detail as follows:

In S801, it is detected whether the charge and discharge data at the current moment satisfies a preset single fluctuation condition;

In S802, if the charge and discharge data at the current moment satisfies the preset single fluctuation condition, it is determined that the charge and discharge data at the current moment meets the preset fluctuation condition;

In S803, if the charge and discharge data at the current moment does not meet the preset single fluctuation condition, then check whether the charge and discharge data at the current moment meets the preset cumulative fluctuation condition, and when the charge and discharge data at the current moment meets the preset cumulative fluctuation condition , it is determined that the charge and discharge data at the current moment satisfies the preset fluctuation condition; when the charge and discharge data at the current moment does not meet the preset cumulative fluctuation condition, it is determined that the charge and discharge data at the current moment does not meet the preset fluctuation condition.

In an embodiment of the present invention, the implementation process of S102 in FIG. 1 further includes:

In one embodiment, the charge/discharge data in the second preset time period before the first valid charge/discharge data in the charge/discharge cycle is used as the charge/discharge start data corresponding to the charge/discharge cycle; The charge/discharge data in the second preset time period after the last valid charge/discharge data in the cycle is taken as the charge/discharge end data corresponding to the charge/discharge cycle; the charge/discharge start data, all valid charge/discharge data and the charge/discharge data The end-of-discharge data is stored as charge/discharge cycle data for the battery system.

In this embodiment, the second preset time period may be 1 hour, and the charge/discharge cycle includes a charge cycle, a discharge cycle, and may also include a charge and discharge cycle. When the charge/discharge cycle is a charge/discharge cycle, the charge/discharge data within 1 hour before the first valid charge/discharge data of the charge/discharge cycle is stored as the charge/discharge starting point data, and the charge/discharge data within 1 hour after the last valid charge/discharge data is saved. The charge-discharge data is used as the charge-discharge end data. In this embodiment, the charge-discharge cycle is a cycle including a charge-discharge process, and may also be a cycle including a discharge-charge process.

In this embodiment, when the charging/discharging cycle is a charging cycle, the charging and discharging data within the second preset time period before the first effective charging and discharging data of the charging cycle can also be saved as the charging starting point data, and the charging cycle is also saved. The charge-discharge data within the second preset time period after the last valid charge-discharge data of , is taken as the charge-end data.
