Technical Field

Background
Along with the application of the automatic power battery production line, the formation and capacity division of the battery core become large energy consumption, and how to improve the formation and capacity division efficiency is also more and more important. In practical application, the battery cell of the lithium battery must be charged and activated after the assembly is completed, and the first charging process of the battery cell is called formation, and is used for activating the active material in the battery cell to generate an SEI film (i.e. SolidElectrolyte Interface, solid electrolyte interface film). The battery cells are subjected to formation and then are subjected to capacity division, and the capacity division is to charge and discharge the formed battery cells so as to detect the performance of the battery cells, so that the battery cells are conveniently graded and assembled according to the capacity.
At present, formation/capacity-dividing equipment, such as a formation/capacity-dividing integrated machine, is mainly adopted to realize formation and capacity division of the battery core. In the specific formation/capacity division process, each bank charges, discharges and inverts different battery cells by controlling the whole power modules in the bank (for example, turning on/off the power modules in different phases) to feed back to the power grid. However, it is found in practice that, because the real-time process steps of each storage location are different in the actual operation process of the storage location load, the required power load is in a dynamic change process, so that the problem of three-phase unbalance occurs at the power load end of the formation/capacity-division equipment, which increases the power loss of the power grid line and the distribution transformer and seriously endangers the safe operation of the electrical equipment such as formation/capacity division equipment.
Therefore, it is particularly important to provide a system and a method for realizing an energy balance scheduling strategy in the formation and capacity division process so as to solve the problem of three-phase unbalance possibly occurring in formation/capacity division equipment.

102. And determining a target adjustment scheme for target library phase matching according to the three-phase distribution condition corresponding to the formation/capacity-division equipment.
In the embodiment of the invention, the three-phase distribution condition can be obtained by analyzing the library position working parameters in other library positions by the power management module configured by the target library position, or can be obtained by analyzing by the upper computer according to the library position working parameters of other library positions, and the embodiment of the invention is not limited. Optionally, the three-phase distribution condition may include total three-phase distribution data of a target library level set in which the target library level is located, where the target library level set includes the target library level and an association library level having an association relationship with the target library level. Further optionally, the associated bin having an association with the target bin may include any one of all bins in the formation/capacity-division device, a first adjacent bin adjacent to the target bin, all bins of the same power supply as the power supply corresponding to the target bin, and all bins under adjacent power distribution branches adjacent to a target power distribution branch of the target bin, and optionally, the power supply may be a distribution box, where the power distribution branch is a branch of the distribution box performing a power supply operation on all power supply modules in the bins.
In the embodiment of the present invention, the target adjustment scheme at least includes a phase to which the power module of the target bank currently needs to be started and/or hibernated, and optionally, the target adjustment scheme may further include a number of power modules of the target bank currently needs to be started and/or hibernated, that is, the target adjustment scheme includes a number of power modules corresponding to one or more phases of the target bank currently needs to be started and/or hibernated, for example, 1 power module corresponding to a needs to be started, where each power module corresponding to a phase is used to indicate a power module belonging to the phase, for example, a power module corresponding to a corresponds to a power module belonging to the phase is a power module belonging to the phase.
103. And executing power module adjustment operation on the target library bits according to the target adjustment scheme to start and/or sleep the target power modules matched with the target adjustment scheme in the target library bits.
In the embodiment of the invention, when the target adjustment scheme indicates that a power module corresponding to a certain phase of a required work in a target library position needs to be added, a power module which needs to participate in the battery core formation/capacity division operation is newly added from the power modules corresponding to the phase which is not started; or when the target adjustment scheme indicates that the power module corresponding to a certain phase needing to reduce the required work, the power module corresponding to the phase which does not need to participate in the cell formation/capacity division operation is dormant from the power modules corresponding to the started phase.
It should be noted that, in the embodiment of the present invention, the "sleep" may be completely closed or may be incompletely closed (e.g. sleep), which is not limited by the embodiment of the present invention.
Therefore, when the power supply module of a certain library position in the formation/capacity-dividing equipment is required to be started/dormant, the embodiment of the invention can adaptively adjust the power supply module in the library position in real time according to the three-phase balance condition of the formation/capacity-dividing equipment, thereby not only improving the intelligent degree of the energy supply adjusting system, but also being beneficial to adjusting the power supply phase in the formation/capacity-dividing equipment while starting/dormancy the power supply module in the library position and effectively maintaining the three-phase balance of the power supply of the load end of the formation/capacity-dividing equipment.
In an alternative embodiment, the method may further comprise:
determining total three-phase distribution data of a target library position set where the target library position is located according to library position working parameters of all associated library positions with association relation with the target library position; optionally, the total three-phase distribution data may include a total working electrical parameter corresponding to each phase in the corresponding bin set; optionally, the total operation electrical parameter corresponding to each phase may include the sum of the operation electrical parameters of all power modules of the phase in the corresponding bank bit set.
For example, the real-time working currents of all the power modules corresponding to the a phase, the B phase and the C phase in each of the target library bit sets may be added to obtain the total working currents corresponding to the a phase, the B phase and the C phase, which are used as the total three-phase distribution data of the target library bit sets, for example, the total three-phase distribution data of the target library bit sets may be: the total operating currents corresponding to phases a, B and C are 300A, 400A and 350A, respectively.
It can be seen that this can improve the accuracy and reliability of determining the three-phase balance condition of the formation/capacity device.
Optionally, determining a target adjustment scheme for matching the target library according to the determined three-phase distribution condition corresponding to the formation/capacity-division device may include:
and determining a scheme for enabling the target library position set to meet the first three-phase balance condition by starting and/or dormancy of the power supply modules in the target library position according to the total three-phase distribution data of the target library position set, and taking the scheme as a target adjustment scheme for target library position matching.
Optionally, the bin set satisfying the first three-phase balance condition may be used to indicate that the degree of difference between the total working electrical parameters corresponding to each two phases in the corresponding bin set is smaller than a preset first degree of difference, may also be used to indicate that the degree of three-phase imbalance of the corresponding bin set is smaller than a preset first degree of three-phase imbalance, and may also be used to indicate that the degree of three-phase balance of the corresponding bin set is greater than the preset first degree of three-phase balance. Wherein, the difference degree can adopt any one of a difference value, a variance, a square error and the like; the three-phase imbalance degree calculation method may be any one of a national standard calculation method, a national standard simplified calculation method, an IEEE std 936-1987 calculation method, a American Electrical manufacturers Association (NEMA) calculation method, an International big grid Commission (GIGRE) calculation method, and the like, and the three-phase imbalance degree may be obtained based on the three-phase imbalance degree, for example, the inverse of the three-phase imbalance degree is taken as the three-phase imbalance degree.
Therefore, by implementing the embodiment of the invention, the target adjustment scheme for maintaining the three-phase balance of the target library level set where the target library level is located can be determined, thereby being beneficial to maintaining the three-phase balance of the local library level of the formation/capacity-division equipment and further realizing the three-phase balance of the whole formation/capacity-division equipment.
In this alternative embodiment, as an alternative implementation manner, the method may further include:
when a plurality of schemes capable of enabling the target library level set to meet the first three-phase balance condition are determined, predicting the efficiency of a power supply module in the target library level after the target library level is adjusted based on each of the schemes, and taking the power supply efficiency as the power supply efficiency corresponding to the scheme;
and further screening the scheme with highest power efficiency from all the schemes to be used as a target adjustment scheme for target library phase matching.
Therefore, when the alternative implementation mode is implemented, when various power supply adjustment schemes capable of maintaining three-phase balance of the formation/capacity-division equipment are determined, the scheme with the highest power supply module efficiency is used as the most preferable scheme, so that the improvement of the energy utilization efficiency of the formation/capacity-division equipment is facilitated, the electric energy loss is reduced, and the energy and the carbon are saved.
In another alternative embodiment, determining whether there is a target bank bit for performing the power module adjustment operation in all the bank bits according to the bank bit operation parameter of each bank bit in the formation/capacity-division apparatus may include:
Judging whether first target library bits exist in all library bits according to the library bit working parameters of each library bit in the formation/capacity division equipment, wherein the first target library bits can comprise library bits of which the corresponding library bit working parameters are not matched with the charge/discharge requirement parameters;
when the first target library bit exists in all the library bits, determining that the target library bit needing to execute the power module adjusting operation exists in all the library bits, wherein the target library bit comprises the first target library bit.
Optionally, the charge/discharge demand parameter in each bank is a charge/discharge demand parameter of the battery cell in the corresponding bank in a current stage, where the current stage may be a constant current charge/discharge stage or a constant voltage charge/discharge stage, and the charge/discharge demand parameter may include one or more of a charge/discharge demand current, a charge/discharge demand voltage, and a charge/discharge demand power.
Therefore, in the implementation of the alternative embodiment, the library bit of which the library bit working parameter is not matched with the charge/discharge requirement parameter in the formation/capacity-dividing equipment can be used as the target library bit of the power module to be started/dormant, thereby being beneficial to realizing accurate regulation and control of the power supply power, reducing the difference between the active power and the effective power and effectively avoiding unidirectional tripping of the formation/capacity-dividing equipment.
In this optional embodiment, as an optional implementation manner, determining whether the first target bank bit exists in all the bank bits according to the bank bit working parameter of each bank bit in the formation/capacity-division device may include:
according to the library position working parameters of each library position in the formation/capacity-division equipment and the charge/discharge demand parameters of each library position, determining the working load rate of each started power module in each library position as the real-time load rate of the library position;
judging whether abnormal library bits with real-time load rate not meeting the preset load rate condition exist in all library bits, and when the judgment result is yes, determining that a first target library bit exists in all library bits, wherein the first target library bit comprises the abnormal library bit.
Optionally, the real-time load rate does not meet a preset load rate condition, which indicates that the real-time load rate is not in a preset load rate interval, where the preset load rate interval is used to indicate a load rate interval corresponding to a high-efficiency interval of the power module determined based on a load rate-efficiency curve of the power module.
Therefore, when the work load rate of the power module in the library is not in the load rate interval corresponding to the high-efficiency interval of the power module, the power module in the library is started/dormant, so that the energy utilization efficiency of the formation/capacity-division equipment is improved, the electric energy loss is reduced, and the energy and the carbon are saved.
Optionally, determining the working load rate of each started power module in each bank according to the bank working parameter of each bank in the formation/capacity-division device and the charge/discharge requirement parameter of each bank, as the real-time load rate of the bank, may include:
calculating the ratio between the real-time working electric parameters of each power module started by each library in the formation/capacity division equipment and the maximum working electric parameters of the power module to obtain the working load rate of the power module, wherein the working load rate is used as the real-time load rate of the library; or alternatively, the process may be performed,
and calculating the ratio between the charge/discharge demand parameter of each library and the maximum working electrical parameter sum of all the started power modules in the library to obtain the working load rate of each started power module in the library as the real-time load rate of the library.
For example, if the real-time working current of a power module in a certain bank is 6A and the maximum working current is 25A, the working load rate of the power module may be determined to be 24%, or if 6 power modules with the maximum working current of 25A are started in a certain bank to charge a battery cell with a charge/discharge demand current of 36A, the working load rate of the power module may be determined to be 24%.
Therefore, the implementation of the optional implementation mode can calculate the work load rate of the power supply module according to the real-time work electric parameter or the charge and discharge demand parameter of the battery cell, and the accuracy and the diversity of the work load rate calculation mode are improved.
In this alternative embodiment, as another alternative implementation manner, the library position working parameter of each library position may further include a step file of the library position;
according to the library position working parameter of each library position in the formation/capacity division equipment, judging whether the first target library position exists in all the library positions or not can comprise the following steps:
determining a process flow to be executed by each library position according to the process file of each library position in the formation/capacity division equipment;
judging whether to-be-adjusted library positions of the power supply module or the dormant power supply module are required to be started according to the to-be-executed process flow of each library position or not in all library positions, and determining that a first target library position exists in all library positions when the judgment result is yes, wherein the first target library position comprises the to-be-adjusted library position.
Therefore, when the step file indicates that the power module in the library position needs to be started or dormant, the power module in the library position is started or dormant according to the three-phase balance condition of the formation/capacity-dividing device, so that the three-phase balance of the formation/capacity-dividing device is maintained at the initial stage of the step flow, and the situations that the power module is frequently started to cause lower efficiency and accuracy of battery charging/discharging operation and shorter service life of the power module are reduced.
In this optional embodiment, as a further optional implementation manner, when it is determined that the first target bank bit exists in all the bank bits, the method may further include:
determining at least one first initial adjustment scheme matched with the first target library according to the library working parameters of the first target library and the charge/discharge demand parameters of the first target library, wherein the first initial adjustment scheme comprises the number of power modules which can be started or dormant by the first target library;
according to the total three-phase distribution data of the target library bit set, determining a scheme for enabling the target library bit set to meet a first three-phase balance condition by starting and/or dormancy of a power module in the target library bit set, wherein the scheme is used as a target adjustment scheme for target library bit matching, and the method can comprise the following steps:
when the target library bit comprises a first target library bit, determining the phase of the power supply module which can be started or dormant in the first initial adjustment scheme according to the first initial adjustment scheme and the phase of all the power supply modules in the first target library bit, so as to obtain a candidate adjustment scheme, wherein the candidate adjustment scheme comprises the number of the power supply modules which can be started or dormant and the phase of the power supply modules;
when the number of the candidate adjustment schemes is greater than 1, predicting new total three-phase distribution data of the first library set as three-phase balance effects corresponding to the candidate adjustment schemes after the first target library is adjusted based on the candidate adjustment schemes according to the total three-phase distribution data of the first library set where the first target library is located;
And screening a corresponding scheme with the optimal three-phase balance effect from all the candidate adjustment schemes to be used as a target adjustment scheme for the phase matching of the first target library.
For example, if a plurality of first initial adjustment schemes, such as 3 or 4 power modules in the target bank, are determined, in this case, the optimal target adjustment scheme may be determined by combining the bank operation parameters of the associated bank having an association with the target bank, such as the bank operation parameters of the adjacent bank, and assuming that the total operation currents corresponding to the a phase, the B phase and the C phase in all the associated banks are 500A, 475A and 450A, respectively, then to maintain the three-phase balance, 3 power modules in the target bank should be started, and the most preferred target adjustment scheme should be to start 2 power modules corresponding to the C phase and 1 power module corresponding to the B phase.
Therefore, when the power supply module of a certain storage position needs to be adjusted, the number of the power supply modules actually needed to be adjusted is determined according to the charge/discharge requirements of the power supply modules, and then the scheme capable of optimizing the three-phase balance effect of the formation/capacity-division equipment is determined by combining the three-phase distribution conditions in the formation/capacity-division equipment, so that the matching degree of the charge/discharge requirements of the adjusted power supply modules and the storage position and the three-phase balance conditions can be improved.
In this optional embodiment, optionally, determining at least one first initial adjustment scheme for matching the first target bank according to the bank working parameter of the first target bank and the charge/discharge requirement parameter of the first target bank may include:
determining the number of power modules needing to perform battery cell charging/discharging operation in a first target base according to base working parameters of the first target base, charging/discharging demand parameters of the first target base and a load rate-efficiency relation of the power modules, wherein the number of the power modules needing to perform battery cell charging/discharging operation in the first target base is used as a power supply scheme of the power supply of the first target base, and the power supply scheme is the number of the power modules capable of enabling the work load rate of the power modules performing battery cell charging/discharging operation in the first target base to be in a preset load rate interval, wherein the preset load rate interval comprises a load rate interval corresponding to a high-efficiency interval;
and determining at least one first initial adjustment scheme for the first target library phase matching according to the power supply scheme and the number of started power modules in the first target library phase.
For example, assuming that the load factor interval corresponding to the high efficiency interval of the power modules is 50% -85%, the working current of one power module is 25A, and for the battery cell, 1c=120a, if the actual current required by the battery cell of the target bank is 0.5c=60deg.a, 3 or 4 power modules may be selectively started to serve as the power supply scheme so that the load factor of the power module is in the load factor interval.
Therefore, by implementing the alternative implementation mode, the power supply adjustment scheme for enabling the load rate of the power supply module to be in the load rate interval corresponding to the high-efficiency interval can be determined, so that the charge/discharge requirements of the adjusted power supply module and the storage position can be improved, the energy utilization efficiency of the formation/capacity-division equipment can be further improved, the electric energy loss is reduced, and the energy and the carbon are saved.
In yet another alternative embodiment, determining whether there is a target bank bit for performing the power module adjustment operation in all the bank bits according to the bank bit operation parameter of each bank bit in the formation/capacity-division apparatus may include:
determining total three-phase distribution data of each library bit set in the formation/capacity-division equipment according to the library bit working parameters of each library bit in the formation/capacity-division equipment, wherein an association relationship exists between any two library bits in the library bit set;
judging whether second library bit sets which do not meet the first three-phase balance condition exist in all library bit sets according to the total three-phase distribution data of each library bit set;
and when the judgment result is yes, determining that target library bits needing to execute the power module adjustment operation exist in all library bits, wherein the target library bits comprise at least one second target library bit determined from a second library bit set.
Therefore, when the three-phase distribution condition of the formation/capacity-division equipment is unbalanced, the power supply module in the formation/capacity-division equipment can be adaptively adjusted by implementing the alternative embodiment, so that the three-phase balance of the power supply at the load end of the formation/capacity-division equipment is further effectively maintained.
In this alternative embodiment, as an alternative implementation manner, the method may further include:
determining sub-three-phase distribution data of each library bit in the second library bit set according to the library bit working parameters of each library bit in the second library bit set; the sub three-phase distribution data comprise working electric parameters corresponding to each phase in the corresponding library position; the working electric parameters corresponding to each phase comprise the sum of the working electric parameters of all power supply modules of the phase in the corresponding library position;
and screening at least one second target library bit from the second library bit set according to the sub-three-phase distribution data of each library bit in the second library bit set, wherein the second target library bit comprises library bits with sub-three-phase distribution data matched with the total three-phase distribution data of the second library bit set, and the target library bit is used as the target library bit for executing the power supply adjustment operation.
For example, if the total three-phase distribution data of the second set of library bits and the sub-three-phase distribution data of a library bit in the second set of library bits each show a total operating electrical parameter of the a phase > a total operating electrical parameter of the B phase, then the library bit is the second target library bit.
It can be seen that, implementing this alternative embodiment can determine the second target library position with the same three-phase distribution condition as the second library position set as the library position needing to adjust the power module, so as to maintain the three-phase balance in a single library position while maintaining the three-phase balance of the load side power supply of the formation/capacity-division device.
In this alternative embodiment, as another alternative implementation manner, determining, according to the total three-phase distribution data of the target bin set, a scheme for enabling and/or disabling the power module in the target bin set so that the target bin set meets the first three-phase balance condition, as a target adjustment scheme for matching the target bin, may include:
when the target library bits comprise second target library bits, determining a second initial adjustment scheme matched with a second library bit set according to total three-phase distribution data of the second library bit set, wherein the second initial adjustment scheme comprises a first total number of power modules to be started and phases thereof in the second library bit set, and a second total number of power modules to be dormant and phases thereof;
and determining a scheme for enabling the second library position set to meet the first three-phase balance condition by starting and/or dormancy according to the sub-three-phase distribution data of each second target library position and a second initial adjustment scheme, wherein the second target library position matching target adjustment scheme comprises the first number of power modules to be started in the second target library position and the phase of the power modules, and the second number of the second power modules to be dormant and the phase of the power modules.
For example, the total three-phase distribution data of the second bank set indicates that the total working currents corresponding to the a phase, the B phase and the C phase are 500A, 425A, respectively, and there are two second target banks, the sub-three-phase distribution data of the first second target bank indicates that the working currents corresponding to the a phase, the B phase and the C phase are 75A, 25A, 50A, respectively, and the sub-three-phase distribution data of the second target bank indicates that the working currents corresponding to the a phase, the B phase and the C phase are 75A, 50A, 25A, respectively, then 1 power module corresponding to a in the two second target banks may be dormant, and 1 power module corresponding to B in the first second target bank may be activated, and 1 power module corresponding to C in the second target bank may be activated.
It can be seen that implementing this alternative embodiment can improve the accuracy and reliability of determining the number and phase of power modules that need to be adjusted.
Example two
Referring to fig. 3, fig. 3 is a flowchart illustrating another method for implementing an energy balance scheduling policy according to an embodiment of the present invention. The method for implementing the energy balance scheduling policy described in fig. 3 may be applied to a formation/capacity-dividing device (such as a formation/capacity-dividing integrated machine) of an automatic power battery production line, where the formation/capacity-dividing device includes a plurality of storage locations, each storage location includes a plurality of power modules, and the formation/capacity-dividing device is configured to perform formation/capacity division on a battery cell through a corresponding power module. Optionally, the method may be implemented by an energy supply adjustment system, where the energy supply adjustment system may be integrated in a formation/capacity-dividing device, for example, in a power management module configured in a library or an upper computer of the formation/capacity-dividing device, or may be a local server or a cloud server for processing an energy supply adjustment procedure in a formation/capacity-dividing process. As shown in fig. 3, the method for implementing the energy balance scheduling policy may include the following operations:
201. In the process of executing the cell formation/capacity division operation by the formation/capacity division device, judging whether target library positions needing to execute the power module adjustment operation exist in all library positions according to the library position working parameters of each library position in the formation/capacity division device, and triggering to execute step 202 when the judgment result of step 201 is yes.
202. And determining a target adjustment scheme for target library phase matching according to the three-phase distribution condition corresponding to the formation/capacity-division equipment.
203. And screening the target power supply module matched with the target adjustment scheme from the target library according to the target adjustment scheme and the library working parameters.
In an embodiment of the present invention, optionally, as shown in fig. 2, the target library may include a plurality of power module combinations, where each power module combination includes at least one power module corresponding to each phase; further optionally, in each power module combination, the number of power modules corresponding to each phase is matched, for example, n power module combinations may be included in the target bank, where each power module combination includes 1 power module corresponding to a, 1 power module corresponding to B, and 1 power module of phase C; further optionally, all power modules in each group of power module combinations are connected through a CAN bus and to a power management module. It can be seen that this is advantageous to maintain the three-phase balance of the individual bank bits themselves in the formation/capacity device.
204. And executing power module adjustment operation on the target library bits according to the target adjustment scheme to start and/or sleep the target power modules matched with the target adjustment scheme in the target library bits.
In the embodiment of the present invention, for other descriptions of step 201, step 202 and step 204, please refer to the detailed descriptions of step 101-step 103 in the first embodiment, and the description of the embodiment of the present invention is omitted.
Therefore, when the power supply module of a certain library position in the formation/capacity-dividing equipment is required to be started/dormant, the power supply module in the library position can be adaptively adjusted in real time according to the three-phase balance condition of the formation/capacity-dividing equipment, the intelligent degree of an energy supply adjusting system can be improved, the power supply phase in the formation/capacity-dividing equipment can be adjusted while the power supply module in the library position is started/dormant, the three-phase balance of the power supply of the load end of the formation/capacity-dividing equipment is effectively maintained, in addition, the power supply module required to be adjusted is screened by combining with the working parameters of the library position when the power supply module in the library position is adjusted, and the accuracy and the reliability of the adjustment of the power supply module can be improved.
In an alternative embodiment, selecting a target power module from the target library that matches the target adjustment scheme according to the target adjustment scheme and the library operation parameter may include:
Determining an adjustable power module set in a target library according to the library working parameters;
according to the target adjustment scheme and the predetermined power module screening conditions, determining a target power module matched with the target adjustment scheme from the adjustable power module set, wherein the target power module can comprise the power modules capable of enabling the power module combination to meet the second three-phase balance condition after being started and/or dormant based on the target adjustment scheme.
Optionally, the power module combination satisfying the second three-phase balance condition may be used to indicate that the degree of difference between the combined working electrical parameters corresponding to each two phases in the corresponding power module combination is smaller than a preset second degree of difference, or may be used to indicate that the degree of three-phase imbalance of the corresponding power module combination is smaller than a preset second degree of three-phase imbalance, or may be used to indicate that the degree of three-phase balance of the corresponding bin set is greater than the preset second degree of three-phase balance. The combined operation electric parameters corresponding to each phase may include the sum of the operation electric parameters of the power modules of the corresponding power module combination, where the phase belongs to the phase.
For example, if 1 power module corresponding to a in the target bank is required to be started, and 1 power module corresponding to B phase and C phase of a certain power module combination in the target bank is started, 1 power module corresponding to a in the power module combination is started.
It can be seen that the implementation of this alternative embodiment can maintain the three-phase balance of the single bank bit itself in the formation/capacity-division apparatus while starting/hibernating the power module in the bank bit to meet the charge/discharge requirements of the bank bit and maintaining the three-phase balance of the power supply at the load end of the formation/capacity-division apparatus.
