For example, a first element could be termed a second element, without departing from the scope of the present disclosure, and, similarly, a second element could be termed a first element.
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
The forced air cooling system of the energy storage power station generally comprises an air conditioning system (namely a primary forced cooling system), an air duct system and a battery plug box heat management system, wherein the battery plug box heat management system is divided into a natural cooling subsystem and a forced cooling subsystem (namely a secondary forced cooling system), and the forced cooling subsystem comprises a plurality of fans.
The two-stage forced air cooling system is a mode commonly adopted by the existing internal energy storage power station, namely, air generated by the first-stage forced cooling system is conveyed to a cavity for placing a battery stack through an air duct system, and then air is conveyed to each battery block through a fan in the second-stage forced cooling system. Because the first-stage forced cooling system and the second-stage forced cooling system are independent from each other, the temperature difference in the cell stack cannot be controlled well due to the independent control mode, and the consistency and the service life of the system are influenced.
Based on this, the present embodiment provides a dual-stage wind power control method, as shown in fig. 1, including:
and 101, acquiring an operation mode of a primary forced cooling system.
In this embodiment, the operation modes include a standby mode, a ventilation mode, a cooling mode, a heating mode, and the like, and the specific operation mode included may be selected according to actual situations.
And 102, controlling the running state of a fan of the secondary forced cooling system according to the running mode and the temperature difference of the cell stack.
The battery stack is internally provided with a plurality of temperature acquisition points, and one or more fans are correspondingly arranged near each temperature acquisition point.
In this embodiment, the difference between the maximum temperature and the minimum temperature collected at the same time (at the same time or in the same period of time) is the temperature difference of the cell stack. In other embodiments, the temperature difference of the stack may be determined in other ways.
In this embodiment, according to the different operational mode of one-level forced cooling system, and the different operational state of fan can be controlled to the temperature difference of the battery pile, if the temperature difference is less, the operational mode is when the ventilation mode, can control all fans to open, if, the temperature difference is great again, the operational mode is cold wind or hot-blast mode, can control the fan that the great department of temperature difference corresponds and close etc. through this kind of mode, can link one-level forced cooling system and second grade forced cooling system automatically effectively, prevent second grade forced cooling system's disjointed control, both improved control efficiency, also guarantee the thermal behavior of energy storage power station system, promote system uniformity and life-span.
In a specific embodiment, as shown in fig. 2, step 102 specifically includes:
and 1021, acquiring the temperature difference of the cell stack.
In this embodiment, the temperature difference of the battery stack mainly refers to a difference between a highest temperature and a lowest temperature of a battery cell in the battery stack, which is collected by a BMS (battery management system). The reason for logically influencing the larger temperature difference of the battery cells in the battery stack is that the high temperature end is too high or the low temperature end is too low, or both.
In this embodiment, preferably, step 1021 and the subsequent steps are executed again at intervals of a preset time, on one hand, the temperature of the battery stack can be controlled in real time, and on the other hand, frequent changes of the running state of the blower can be avoided, which is beneficial to the stability of the battery system.
and 1023, closing the corresponding first target fan according to the temperature difference contribution degree of each fan in the running fans.
Specifically, assuming that the number difference of 99 collection points is only 5 ℃ in total 100 temperature collection points in the battery stack, if the remaining 1 collection point is counted (the positive deviation or the negative deviation of the remaining 99 collection point values is large), the temperature difference of the battery cell in the stack can reach 12 ℃, and at this time, it can be determined that the temperature difference contribution degree of the collection point is the highest. It should be understood that the manner and specific numerical values therein are merely illustrative of distances and should not be construed as limiting the present embodiment.
In this embodiment, the corresponding preset high-temperature section is obtained according to the operation mode, and if the temperature difference of the cell stack is located in the preset high-temperature section, it indicates that the temperature of each part of the cell stack is not uniform, and the stability and the service life of the cell system are easily affected.
In step 1023, there are various ways to obtain the corresponding first target fan, and several specific ways are listed below as examples, but it should be understood that the following ways should not be construed as limiting the embodiment:
the method I comprises the following steps:
as shown in fig. 3, step 1023 includes the following steps:
Wherein a first number of fans to be switched off is set in advance for different operating modes.
And 11232, sequencing the running fans according to the contribution degree of the temperature difference from high to low.
For example, in the cooling mode, the collected fan corresponding to the lowest temperature may be used as the fan with the highest temperature difference contribution degree, the collected fan corresponding to the second lowest temperature may be used as the fan with the second highest temperature difference contribution degree, and so on; in a heating mode, the fan corresponding to the acquired highest temperature can be used as the fan with the highest temperature difference contribution degree, the fan corresponding to the acquired second highest temperature can be used as the fan with the second highest temperature difference contribution degree, and the like; in the ventilation mode, the highest temperature and the lowest temperature which are collected can be used as the fan with the highest temperature difference contribution degree, the fan with the second lowest temperature and the fan with the second highest temperature which are collected can be used as the fan with the second highest temperature difference contribution degree, and the like.
And 11233, taking the first number of fans in front as the first target fans.
Namely, the fan with the contribution degree ranked in the front is taken as the first target fan.
In this embodiment, the first number of corresponding fans to be turned off can be obtained according to different operation modes, the first number of fans can be turned off from front to back according to the sorting of the temperature difference contribution degrees, and the fans of different numbers can be turned off according to different operation modes, so that the control is performed in a targeted manner.
The second method comprises the following steps:
in this way, the preset high-temperature section includes a plurality of sub-high-temperature sections, that is, the preset high-temperature section includes sub-high-temperature sections of different levels, for example, the first temperature to the second temperature are sub-high-temperature sections of the first level, the second temperature to the third temperature are sub-high-temperature sections of the second level, and so on. The number and the range of the specific sub-high temperature intervals can be determined according to actual conditions.
As shown in fig. 4, step 1023 includes the following steps:
in step 12231, if the temperature difference is located in one of the sub-high temperature ranges, a second number corresponding to the sub-high temperature range is obtained.
For example, if the temperature difference is located in the second-level sub-high temperature interval, the second number corresponding to the second-level sub-high temperature interval is obtained. In this embodiment, the higher the level (the greater the temperature difference requirement), the greater the number of fans that need to be shut down.
12232, sorting the running fans according to the contribution degree of the temperature difference from high to low;
12233, taking the second number of fans positioned in front as first target fans;
In the embodiment, the plurality of sub high-temperature intervals in different levels are subdivided, the higher the level is, the more the fans need to be turned off, and in this way, the fans can be finely controlled, so that the running state of the fans can be more accurately controlled.
The third method comprises the following steps:
in step 1023, if the operation mode of the primary forced cooling system is a refrigeration mode, the first target fan is a fan corresponding to a low-temperature area; and if the operation mode of the primary forced cooling system is a heating mode, the first target fan is a fan corresponding to the high-temperature area.
In this embodiment, if the operation mode is the cooling mode, the low temperature has a greater influence on the temperature of the entire battery system, and therefore, the first target fan is selected from the fans corresponding to the low-temperature region, for example, the fan corresponding to the acquired lowest temperature may be used as the first target fan; if the operation mode is a heating mode, the influence of high temperature on the temperature of the whole battery system is larger, and therefore, a first target fan is selected from fans corresponding to a high-temperature area, for example, a fan corresponding to the acquired highest temperature can be used as the first target fan.
In one embodiment, as shown in fig. 5, after step 1023, if the temperature difference of the cell stack is not in the preset low temperature difference interval, the step 1021 is returned until the temperature difference of the cell stack is in the preset low temperature difference interval.
Specifically, when the temperature difference of the cell stack is within the preset low temperature difference range, step 1024 is executed, and if the temperature difference of the cell stack is within the preset low temperature difference range, the second target blower is turned on.
Wherein the second target fan represents all fans of the secondary forced cooling system.
It should be appreciated that step 1024 may be located anywhere after step 1021.
In this embodiment, if the temperature difference of the cell stack is within the preset low temperature difference range, it indicates that the temperature difference inside the cell stack is not large, and therefore, the heating, cooling or ventilating efficiency of the cell stack can be improved by turning on all the fans.
In this embodiment, before the step of setting the temperature difference of the cell stack in the preset low temperature difference range, the method may further include:
and acquiring a corresponding preset low temperature difference interval according to the operation mode.
In the embodiment, different preset low temperature difference intervals can be obtained according to different operation modes, so that the starting of all fans can be controlled in different operation modes in a targeted manner.
In order to better understand the overall process of the present embodiment, the following describes the present embodiment by a specific example:
fig. 6 schematically shows a control flow diagram in a specific scenario in which the blower components in the secondary forced cooling system default to a fully off state if the primary forced cooling system is in a standby mode, i.e., the air conditioning system is in an off mode.
If the primary forced cooling system is in a ventilation mode, that is, the air conditioning system is in a working condition of only starting a fan in the air conditioning system, and the temperature difference value in the actual battery stack collected by the BMS system is in a subdivided low temperature difference region (in this embodiment, the subdivided low temperature difference region is a specific implementation manner of a preset low temperature interval), the fan components in the secondary forced cooling system are defaulted to be in a full-on state; if the temperature difference value in the actual battery stack collected by the BMS system is in the subdivided high temperature difference region (in this embodiment, the subdivided high temperature difference region is a specific implementation manner of the preset high temperature interval), the n1 fan components with the largest temperature difference contribution degree in the secondary forced cooling system are turned off.
If the primary forced cooling system is in a refrigeration mode, and the actual temperature difference value in the battery stack collected by the BMS system is in the subdivided low temperature difference region, default fan components in the secondary forced cooling system to be in a full-on state; and if the temperature difference value in the actual battery stack collected by the BMS system is in the subdivided high temperature difference region, closing the n2 fan components with the maximum temperature difference contribution in the secondary forced cooling system.
If the primary forced cooling system is in a heating mode, and the temperature difference value in the actual battery stack acquired by the BMS system is in the subdivided low temperature difference region, default wind turbine components in the secondary forced cooling system are all in an opening state; and if the temperature difference value in the actual battery stack collected by the BMS system is in the subdivided high temperature difference region, the n3 fan components with the largest temperature difference contribution degree in the secondary forced cooling system are closed.
If the primary forced cooling system is in the mode N, and the temperature difference value in the actual battery stack acquired by the BMS system is in the subdivided low temperature difference region, default wind turbine components in the secondary forced cooling system are all in the on state; and if the temperature difference value in the actual battery stack collected by the BMS system is in the subdivided high temperature difference region, closing the n fan components with the largest temperature difference contribution degree in the secondary forced cooling system.
