At present, when the charge-discharge pile is in a working state, a power module inside the charge-discharge pile can generate large noise, and then troubles can be caused to the life of people.
In order to solve the technical problems, the application provides a charging and discharging control method for a charging and discharging pile, so as to reduce noise pollution caused by the charging and discharging pile during working.

The charging and discharging control method for the charging and discharging pile and the corresponding beneficial effects provided by the application are explained by a plurality of embodiments as follows.
Fig. 3 is a schematic flow chart of a charging and discharging control method for a charging and discharging pile provided in an embodiment of the present application, and optionally, an execution main body of the method may be a control device such as the main control unit shown in fig. 1, and the method has a data processing function. It should be understood that in other embodiments, the order of some steps in the charging and discharging control method for the charging and discharging pile may be interchanged according to actual needs, or some steps may be omitted or deleted. As shown in fig. 3, the method includes:
s301, receiving battery parameter information of the charging and discharging equipment connected to the charging and discharging pile.
Optionally, when the "charging and discharging device" needs to start charging and discharging operations, the charging gun on the charging and discharging pile side may be inserted into the charging interface of the "charging and discharging device", at this time, the BMS in the "charging and discharging device" is connected to the charging and discharging pile through the CAN bus, and the BMS periodically transmits the basic parameter information of the battery to the main control unit in the charging and discharging pile.
S302, determining the number of expected charging and discharging modules and the residual charging and discharging time of the battery of the charging and discharging equipment according to the battery parameter information.
The expected number of the charge-discharge modules refers to the number of the charge-discharge modules which should be provided on the side of the charge-discharge pile according to the charge-discharge power required by the charge-discharge equipment. It can also be understood that, when the charging power required by the "charging and discharging device" is constant, the greater the number of charging and discharging modules provided on the charging and discharging pile side, the more efficient the "charging and discharging device" can complete the charging and discharging operation.
The remaining charge-discharge time of the battery of the charge-discharge equipment refers to the charge-discharge time remaining when the battery of the current charge-discharge equipment completes the charge-discharge operation.
In this embodiment, the main control unit may calculate, according to the battery parameter information, the expected number of the charge and discharge modules and the remaining charge and discharge time of the battery of the charge and discharge device.
And S303, acquiring a noise value of the charging and discharging pile in the current working process, which is detected by a sound detection unit arranged in the charging and discharging pile.
When the charging and discharging pile works, the charging and discharging module in the charging and discharging pile can generate large noise. For example, when the number of "charge and discharge modules" in an operating state in the charge and discharge pile is larger, the noise generated is also larger accordingly.
Illustratively, the sound detection unit may be a noise meter or the like, and may be used to detect a noise value generated when the charge and discharge pile operates.
Therefore, in this embodiment, the main control unit further needs to acquire the noise value of the charging and discharging pile detected by the sound detection unit in real time during the current operation, so that the number of the actual charging and discharging modules can be flexibly adjusted by combining the noise value of the charging and discharging pile during the current operation.
S304, determining the number of the actual charging and discharging modules according to the noise value, the expected number of the charging and discharging modules and the remaining charging and discharging duration of the battery.
In this embodiment, the main control unit needs to flexibly adjust the number of the actual charging and discharging modules by simultaneously combining the current working noise value of the charging and discharging pile, the expected number of the charging and discharging modules and the remaining charging and discharging time of the battery, so that the noise value generated by the charging and discharging pile during working can be effectively reduced, and meanwhile, the charging and discharging efficiency of the charging and discharging equipment can be ensured.
It should be noted that, in an implementation manner, if the expected number of charge-discharge modules required by the "charge-discharge device" is directly used to charge and discharge the battery of the charge-discharge device, although the maximum charge-discharge efficiency of the charge-discharge device can be ensured, the noise generated by the "charge-discharge pile" is easily increased.
Therefore, in this embodiment, it is proposed to determine the actual number of the charge and discharge modules by combining the "noise value of the charge and discharge pile during the current operation," the expected number of the charge and discharge modules "and" the remaining charge and discharge time of the battery "at the same time, so as to effectively reduce the noise caused by the" charge and discharge pile "during the operation.
And S305, controlling the charge-discharge modules with the actual number of the charge-discharge modules to charge and discharge the battery of the charge-discharge equipment.
On the basis of the above embodiment, after the "actual number of charge and discharge modules" is determined, the main control unit of the charge and discharge pile sends a charge and discharge work instruction to the "charge and discharge modules with the actual number of charge and discharge modules" through the control unit, so that the charge and discharge of the "battery of the charge and discharge equipment" can be performed through the charge and discharge modules with the actual number of charge and discharge modules, and thus, not only can the noise value generated when the charge and discharge pile works be effectively reduced, but also the charge and discharge efficiency of the charge and discharge equipment can be ensured.
To sum up, the embodiment of the present application provides a charge and discharge control method for a charge and discharge pile, including: receiving battery parameter information of charging and discharging equipment connected to the charging and discharging pile; determining the number of expected charging and discharging modules and the residual charging and discharging duration of the battery of the charging and discharging equipment according to the battery parameter information; acquiring a noise value of the charging and discharging pile in the current working process, which is detected by a sound detection unit arranged in the charging and discharging pile; determining the number of actual charge and discharge modules according to the noise value, the expected number of charge and discharge modules and the residual charge and discharge duration of the battery; and the charge-discharge modules controlling the number of the actual charge-discharge modules charge and discharge the batteries of the charge-discharge equipment. In the scheme, three measurement indexes of the noise value of the charging and discharging pile in the current working process, the expected number of the charging and discharging modules and the residual charging and discharging time of the battery are combined at the same time, and the actual number of the charging and discharging modules is flexibly adjusted, so that the noise value of the charging and discharging pile generated in the working process can be effectively reduced, the charging and discharging efficiency of charging and discharging equipment can be ensured, and the noise problem generated by the charging and discharging pile is effectively solved.
The following three conditions are combined to specifically explain how to determine the actual number of the charge and discharge modules according to the noise value, the expected number of the charge and discharge modules and the remaining charge and discharge time of the battery.
Wherein the detected current noise value is recorded as ADv; the preset noise threshold is recorded as ADset.
The residual charge-discharge time of the battery is recorded as Tcharge; and recording the preset residual charge-discharge time threshold as Tset.
In the first case, when the detected current noise value is less than or equal to the preset noise threshold (ADv < ═ ADset), specifically as follows:
optionally, determining the number of the actual charge and discharge modules according to the noise value, the expected number of the charge and discharge modules, and the remaining charge and discharge duration of the battery, includes:
and if the noise value is less than or equal to the preset noise threshold value, determining the number of the actual charging and discharging modules as the expected number of the charging and discharging modules.
In this embodiment, the main control unit compares the noise value ADv of the charging and discharging pile detected by the sound detection unit in real time when the pile is currently operating with the preset noise threshold value ADset, and if the current detected noise value ADv is less than or equal to the preset noise threshold value ADset, that is, ADv ═ ADset, it may be considered that the noise value ADv generated by the current charging and discharging pile is within an acceptable range, and the main control unit does not need to adjust the number of the charging and discharging modules in operation in the charging and discharging pile. At this time, the actual number of the charge and discharge modules can be further determined according to the expected number of the charge and discharge modules required by the charge and discharge equipment, that is, the actual number of the charge and discharge modules is the expected number of the charge and discharge modules.
In the second case, when the detected current noise value is greater than the preset noise threshold (ADv > ADset), the following is specified:
as shown in fig. 4, the determining the actual number of the charge/discharge modules according to the noise value, the expected number of the charge/discharge modules, and the remaining charge/discharge time of the battery further includes:
s401, if the noise value is larger than a preset noise threshold, judging whether the residual charge-discharge time length of the battery is larger than a preset residual charge-discharge time length threshold.
In this embodiment, if the current detected noise value ADv is greater than the preset noise threshold value ADset, that is, ADv > ADset, the remaining charge-discharge time duration of the battery still needs to be determined, and the remaining charge-discharge time duration of the battery is compared with the preset remaining charge-discharge time duration threshold value, so as to further determine the number of actual charge-discharge modules according to the comparison result between the remaining charge-discharge time duration of the battery and the preset remaining charge-discharge time duration threshold value.
And S402, if yes, determining that the number of the actual charging and discharging modules is the number obtained by subtracting 1 from the expected number of the charging and discharging modules.
Optionally, if the current detected noise value ADv is greater than the preset noise threshold value ADset, and the remaining charge-discharge time length Tcharge of the battery is also greater than the preset remaining charge-discharge time length threshold value Tset, that is, both the current detected noise value ADv and the remaining charge-discharge time length Tcharge of the battery are greater than the respective preset threshold values, the number of charge-discharge modules in operation in the charge-discharge pile needs to be adjusted, and at this time, the actual number Ract of the charge-discharge modules is a value obtained by subtracting 1 from the expected number Rcau of the charge-discharge modules.
After the actual number of the charge and discharge modules is obtained in the above step S402, the charge and discharge modules of the actual number of the charge and discharge modules are controlled to be started for charge and discharge. While these charge-discharge modules are operating, the following embodiments are continued to be implemented.
Specifically, after the actual number of the charge and discharge modules (that is, the expected number Rcau of the charge and discharge modules minus 1) is obtained and the charge and discharge modules of the actual number of the charge and discharge modules are started, the currently detected noise value ADv and the remaining charge and discharge time length Tcharge of the battery are continuously judged to determine whether the currently obtained actual number of the charge and discharge modules is reasonable. The specific judgment process is as follows:
as shown in fig. 5, after step S402, the method further includes:
s501, acquiring an updated noise value of the charge-discharge pile when the charge-discharge pile charges and discharges by the charge-discharge modules with the actual number of the charge-discharge modules.
On the basis of the above embodiment, after the actual number of the charge and discharge modules is determined, the main control unit further needs to continuously read the updated noise value of the charge and discharge pile detected by the sound detection unit when the charge and discharge pile charges and discharges the charge and discharge pile through the charge and discharge modules with the actual number of the charge and discharge modules, so as to determine whether the noise generated by the charge and discharge pile when the charge and discharge pile charges and discharges through the charge and discharge modules with the actual number of the charge and discharge modules is within the acceptable range.
S502, judging whether the noise updating value is larger than the noise threshold value.
And S503, judging whether the residual charge-discharge time length of the battery is larger than the residual charge-discharge time length threshold value.
And S504, if the noise update value is larger than the noise threshold value and the remaining charge-discharge time length of the battery is larger than the remaining charge-discharge time length threshold value, subtracting 1 from the actual number of the charge-discharge modules to obtain a new actual number of the charge-discharge modules.
In an implementation manner, for example, if the detected noise update value is greater than the noise threshold and the remaining charge-discharge time period of the battery is also greater than the remaining charge-discharge time period threshold, it indicates that the noise generated when the charge-discharge pile charges and discharges the charge-discharge module with the actual number of the charge-discharge modules exceeds the acceptable range and the remaining charge-discharge time period of the battery also exceeds the remaining charge-discharge time period threshold, that is, the main control unit needs to continue to adjust the actual charge-discharge modules, subtract 1 from the actual number of the charge-discharge modules to obtain a new actual number of the charge-discharge modules, until the noise update value when the charge-discharge pile charges and discharges the charge-discharge module with the new actual number of the charge-discharge modules is less than the noise threshold, then the charge-discharge module with the new actual number of the charge-discharge modules is used to charge and discharge the battery of the charge-discharge device, the number of actual charging and discharging modules in the charging and discharging pile can be flexibly adjusted, and the noise value generated when the charging and discharging pile works is effectively reduced.
And S505, controlling the charge-discharge modules with the new actual number of the charge-discharge modules to charge and discharge the battery of the charge-discharge equipment.
It should be noted that the above steps S501 to S504 are executed in a loop. Specifically, the main control unit controls the charge-discharge modules with the new actual number of the charge-discharge modules to charge and discharge the battery of the charge-discharge device, and then executes the steps S501-S504 in a circulating manner until the obtained updated noise value of the charge-discharge pile during the charge-discharge with the charge-discharge modules with the actual number of the charge-discharge modules is smaller than the noise threshold value, so that the steps S501-S504 do not need to be executed in a circulating manner, and at the moment, the main control unit can control the charge-discharge modules with the new actual number of the charge-discharge modules to charge and discharge the battery of the charge-discharge device, so that the noise value generated during the operation of the charge-discharge pile can be effectively reduced, the charge-discharge efficiency of the charge-discharge device can be ensured, and the problem of noise generated by the charge-discharge pile is effectively solved.
In the third case, when the detected current noise value is greater than the preset noise threshold and the remaining charge-discharge time period of the battery is less than or equal to the remaining charge-discharge time period threshold (ADv > ADset, Tcharge ═ Tset), specifically, the following is performed:
optionally, in another implementation manner, if the noise value is greater than the preset noise threshold and the remaining charging and discharging time period of the battery is less than or equal to the remaining charging and discharging time period threshold, determining that the actual number of the charging and discharging modules is the expected number of the charging and discharging modules.
In this embodiment, if the currently detected noise value ADv is greater than the set value ADset, and the remaining charging and discharging time length Tcharge of the battery is less than the remaining charging and discharging time length threshold Tset, the main control unit does not need to adjust the number of the charging and discharging modules in operation in the charging and discharging pile in order to save the charging and discharging time of the user and ensure the charging and discharging efficiency of the charging and discharging device. At this time, the actual number of the charge and discharge modules can be determined according to the expected number of the charge and discharge modules required by the charge and discharge equipment, that is, the actual number of the charge and discharge modules is the expected number of the charge and discharge modules.
The following embodiments specifically explain how to determine the expected number of charge and discharge modules and the remaining charge and discharge time of the battery of the charge and discharge device according to the battery parameter information.

In this embodiment, the voltage U may be determined according to the rated voltage of the batteryForehead (forehead)Rated current IForehead (forehead)The power value required by the battery, i.e., P, is calculatedForehead (forehead)＝UForehead (forehead)*IForehead (forehead)。
Assuming that the power value of each charge-discharge module is P1, the expected number Rcau of charge-discharge modules is PForehead (forehead)/P1。
In this embodiment, in order to ensure that the calculated expected number of charge/discharge modules is an integer, the result of the ratio between the "power value required by the battery" and the "power value of each charge/discharge module" is rounded, and then the value obtained by adding 1 to the rounded value is used as the expected number of charge/discharge modules.
For example, if the power value required by the battery is 25KW, and the power value of each charge-discharge module is 10KW, the ratio of "the power value 25KW required by the battery" to "the power value 10KW of each charge-discharge module" is 2.5, and then, the value obtained by rounding 2.5 and adding 1 is 3. Therefore, the expected number of charge and discharge modules is 3.
Optionally, in the step S302, determining a remaining charge-discharge time of the battery according to the battery parameter information includes:
and calculating the residual charge-discharge time of the battery according to the rated capacity, the current battery capacity and the power value required by the battery.
In this embodiment, the remaining charge/discharge time period Tcharge of the battery is (1-current battery capacity) per rated capacity/power value required by the battery.
