Referring to fig. 1, a control method for battery management includes S10 to S40, specifically including the steps of:
s10: and acquiring battery operation parameter information.
Specifically, the battery cell is provided with a voltage sensor, a temperature sensor and a current sensor, and is used for acquiring the operation parameter information of each battery cell by the system. The system collects initial voltage, initial temperature and initial current data of each battery through the sensor according to a preset interval duration, for example, the preset interval duration is 5 minutes. The system then calculates the initial capacitance of each cell from the collected initial voltage and initial current by the existing voltage-current integration formula. The system takes the acquired initial voltage, initial temperature and initial capacitance of all the batteries as an original data set. The system then inputs the raw data set into a preset data processing algorithm, for example, the data processing algorithm including, for example, a filtering algorithm. The algorithm screens out data except values in a data set and unreasonably jumped data as abnormal points according to a historical normal data interval. After filtering, the system obtains the operating battery voltage, the operating battery temperature and the operating battery capacitance of each battery as battery operating parameter information. And finally, the system stores the operation parameter information of each battery into a database as an important reference basis for battery management and fault analysis. By the technology, the system can efficiently monitor and record the running condition of each battery in real time, and provides technical support for the optimal management of the battery pack.
S20: and determining the battery operation state corresponding to the battery operation parameter information according to a preset operation state monitoring algorithm.
Specifically, the preset operating state monitoring algorithm is a method for determining the operating state of the battery. After the system acquires the battery operation battery voltage, the operation battery temperature and the operation battery capacitance information, the operation state of the battery can be deduced by carrying out the identification of a preset operation state monitoring algorithm on the battery operation parameter, for example, the preset operation state monitoring algorithm is a differential algorithm used for differential operation and analysis.
The specific steps include S21 to S23:
s21: attaching corresponding time labels to the battery operating voltage and the battery operating temperature; and dividing according to the battery operating voltage and the battery operating temperature with the time labels and the preset interval duration to obtain a plurality of time sequence data sets.
For example, in order to efficiently monitor the change rule of the battery operation parameters, the following technical solutions are provided in the embodiments of the present application: and the battery operation voltage and battery operation temperature data set is obtained through the pre-processing of the operation voltage and temperature data of each battery acquired by the system. The system then divides the data set of operating parameter values, the specific process comprising: and the system attaches a corresponding time tag to each operation parameter value according to the time point of data acquisition. Then, the system divides the data set of the newly added time tag according to a preset acquisition interval time length, for example, the acquisition interval time length is 1 hour. I.e. by 1 hour as a time unit, the values of the plurality of operating parameters are trimmed within the same time unit. In this way, a plurality of operating parameter time series data sets are obtained which are presented in time series. Finally, the system stores the time sequence data set and provides support for the analysis and prediction of the variation trend of the subsequent parameters. The process can realize the efficient unified management of the battery operation data, and is helpful for understanding the battery operation rule and carrying out condition diagnosis.
S22: according to a preset differential formula, calculating voltage change rates and temperature change rates corresponding to a plurality of time sequence data sets; and determining the running state of the battery according to the voltage change rate and the temperature change rate.
The system acquires a plurality of time series data sets, compares the data of two adjacent time points according to a preset differential formula, and calculates the change rate of the data. The specific process comprises the following steps: for a voltage data set, the system calculates the rate of change of the voltage value, i.e., the rate of change of the voltage, over each time period. For a temperature dataset, the system also calculates the rate of change of the temperature value, i.e. the rate of change of temperature, over each time period. Then, the system compares the voltage change rate and the temperature change rate with a preset safety standard charging parameter threshold value, and determines the running state of the battery according to the comparison result, wherein the battery running state identification process comprises the following steps: the system judges the voltage change rate, and if the voltage change rate is smaller than a preset voltage change rate threshold, the system judges that the battery is in a stable state, wherein the voltage fluctuation is smaller. If the voltage change rate is larger than a preset voltage change rate threshold, the voltage change rate is further judged to be positive or negative, and if the voltage change rate is positive, the system judges that the battery is in a charging state; if the rate of change of voltage is negative, the system determines that the battery is in a discharged state. The system judges the temperature change rate at the same time, and if the temperature change rate is larger than a preset temperature change rate threshold value, the system judges that the battery is in a high-load operation state. The recognition result is used for the system to take corresponding control strategies, such as adjusting the charge and discharge rate and the like.
S30: and inquiring target battery parameter information corresponding to the battery running state in the database, wherein the target battery parameter information comprises target battery voltage, target battery temperature and target battery capacitance.
Specifically, the system is based on the obtained battery operating state. The database is queried. The database stores target battery operating parameter information for various battery states. For example, in a steady state, the target voltage is between 3.7 and 3.8V, in a charged state, the target temperature is controlled between 25 and 35 degrees celsius, in a high load state, the target capacitance should be controlled above 80% of the design value, and specific values of the target battery operating parameter information can be set by staff according to historical data. The system obtains the target voltage, temperature and capacitance reference value which accord with the current battery state through database inquiry. The system can adjust related control parameters according to the deviation of the measured value and the reference value, so that the actual value approaches the target interval. The function is helpful for guiding the control system to realize more refined battery state management and parameter optimization control.
S40: comparing each operation parameter in the battery operation parameter information with each corresponding target parameter in the target battery parameter information to obtain a comparison result, and determining corresponding battery adjustment information; based on the battery adjustment information, a corresponding control instruction is generated and sent to the battery control terminal to control the running state of the battery to be matched with the target battery state.
Specifically, the system compares the obtained battery operation voltage, battery operation temperature and battery operation capacitance with a target battery voltage, target battery temperature and target battery capacitance corresponding to the battery operation state, respectively, and the comparison process comprises: the system calculates the difference between the detected battery running voltage value and the set battery target voltage value to obtain a specific voltage difference value. The system also obtains a temperature difference between the actual temperature value and the target temperature value and a capacitance difference between the capacitance value and the target capacitance value for the temperature parameter and the capacitance parameter, respectively. Then the system calculates the parameter difference according to a preset battery evaluation weight formula, wherein the formula specifically comprises the following steps:
wherein C is a battery evaluation value, R 1 For presetting the voltage weight, R 2 R is a preset temperature weight 3 To preset the capacitance weight, T 1 Is the voltage difference, T 2 For the temperature difference, T 3 Is the capacitance difference.
And the system brings the voltage difference value, the temperature difference value and the capacitance difference value into the preset battery evaluation weight formula for calculation, and obtains a corresponding battery evaluation value. And the system searches a corresponding battery adjustment scheme in the mapping table according to the obtained battery evaluation value. The regulation scheme comprises a regulation method aiming at voltage and a regulation scheme aiming at power output, the system generates a control instruction corresponding to each parameter regulation in the regulation scheme according to the regulation scheme obtained by searching, namely battery regulation information, and sends the control instruction to a battery control terminal, and the battery control terminal is used for optimally regulating the power supply voltage of a battery in a form of sending a control signal according to the control instruction; and according to the power output adjustment information, adjusting the power of the battery when the battery supplies power to the load, and completing the optimization and the treatment of the battery state.
In a preferred embodiment of the present application, the system monitors the charge rate and discharge rate of the battery in real time, and the process specifically includes: the system acquires charge and discharge rate data of the battery pack battery and judges whether the charge rate and the discharge rate value of the current battery are within a preset safe charge and discharge rate range. If both the charge rate and discharge rate parameters are within the safe range, the system continues to monitor. If either rate parameter is outside of the safe range, the system determines that the battery is in an abnormal state and then stops power output to the battery. Meanwhile, the system generates early warning information of abnormal charge and discharge of the battery and sends the early warning information to the mobile terminal of the user in real time in a short message or telephone mode. Through the speed monitoring and the safety early warning of the system, the protection of the battery charging and discharging process is realized, and the safety of the system is improved.
