[0057] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0058] In the description of the present application, "module" and "processor" may include hardware, software or a combination of the two. A module may include hardware circuits, various suitable sensors, communication ports, memory, and may also include software parts, such as program code, or a combination of software and hardware.

The term "at least one A or B" or "at least one of A and B" has a similar meaning to "A and / or B" and may include only A, only B or A and B. The singular terms "one" and "the" may also include plural forms.

[0059] Here we first explain some terms involved in this application.

[0060] Dew point: Under a fixed air pressure, the temperature to which the gaseous water in the air needs to drop to reach saturation and condense into liquid water.

[0061] Currently, most energy storage systems use liquid cooling systems for heat dissipation. When the water outlet temperature of the liquid cooling system is lower than the ambient temperature and the ambient humidity is high, condensation will occur in the system. There are two situations in which condensation occurs. One is that in a high temperature and high humidity environment, the operation and maintenance personnel open the door of the energy storage system, and condensation is generated after the outside air enters. Secondly, condensation is generated when the door of the energy storage system is in a closed state. When too much condensation is generated in these two situations, it will fall on the electrical components of the energy storage system, causing a short circuit in the electrical components, and then causing the energy storage system to fail.

[0062] Based on this, in order to solve the above technical problems, the technical concept of the present application is to provide a new anti-condensation control method for an energy storage system to prevent condensation from occurring in the energy storage system.

[0063] Figure 1 Schematic diagram of the structure of an energy storage system provided in an embodiment of the present application. Figure 1 As shown, the energy storage system includes: a plurality of thermometers and hygrometers 11, a control device 12, a heating device 13, a system pipeline 14, a pack cold plate 15, and a battery unit 16. The thermometers and hygrometers 11 collect the liquid outlet temperature, the temperature and humidity of different detection points in the energy storage system, and send the collected data to the control device 12. The control device 12 obtains the dew points corresponding to the different detection points according to the temperature and humidity of the different detection points, and obtains the minimum dew point from the dew points corresponding to the different detection points. When it is determined that the difference between the minimum dew point and the liquid outlet temperature is less than the first temperature margin, a heating instruction is sent to the heating device 13, and the heating device 13 performs heating treatment on the liquid in the liquid cooling device. During the heating process, the control device 12 monitors the liquid outlet temperature, and when it is determined that the liquid outlet temperature is greater than the sum of the minimum dew point, the first temperature margin and the first temperature threshold, the liquid cooling control device 12 sends a stop heating instruction to the heating device 13. After receiving the stop heating instruction, the heating device 13 stops the heating treatment.

[0064] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0065] Figure 2 1 is a flow chart of an embodiment 1 of an energy storage system anti-condensation control method provided in the present application. Figure 2 As shown, specifically, the method includes:

[0066] Step S201: obtaining the liquid outlet temperature, the temperature and humidity of multiple detection points.

[0067] In this embodiment, the energy storage system can heat or cool the liquid in the liquid cooling device, and the temperature of the liquid after the energy storage system heats or cools the liquid in the liquid cooling device is the liquid outlet temperature.

[0068] In this embodiment, since the energy storage system is large in size, the temperature and humidity at different locations are different. Therefore, it is necessary to set thermometers and hygrometers at multiple locations of the energy storage system to collect the temperature and humidity at multiple locations.

[0069] Step S202: obtaining dew points of the multiple detection points according to the temperatures and humidities of the multiple detection points.

[0070] In this embodiment, at the i-th detection point, the relationship coefficient between temperature and humidity is obtained based on the temperature and humidity of the i-th detection point, and then the dew point of the i-th detection point is obtained based on the relationship coefficient and the first preset value and the second preset value.

[0071] In this embodiment, according to Formula 1:

[0072]

[0073] Get dew point T d , where a is 17.27, b is 237.7, a and b are constants, T is temperature, RH is humidity,

[0074] In this embodiment, the dew point at each position is calculated by Formula 1.

[0075] In this embodiment, a is a first preset value, b is a second preset value, and γ(T, RH) is a relationship coefficient.

[0076] Step S203: Obtain the minimum dew point according to the dew points of multiple detection points.

[0077] In this embodiment, the dew points of the multiple detection points are sorted from large to small, and the last dew point is taken as the minimum dew point.

[0078] Step S204: determine that the difference between the minimum dew point and the liquid outlet temperature is less than the first temperature margin, and heat the liquid in the liquid cooling device.

[0079] In this embodiment, when the liquid cooling device cools the battery unit of the energy storage system, as the temperature of the liquid in the liquid cooling device continues to decrease, condensation is most likely to occur at the location where the minimum dew point is located. Therefore, when it is determined that the difference between the minimum dew point of the detection point and the outlet liquid temperature is less than the first temperature margin, the liquid in the liquid cooling device is heated to reduce the dew point of the detection point by increasing the outlet liquid temperature, thereby preventing condensation from occurring at the detection point.

[0080] In this embodiment, the first temperature margin is set to avoid heating when the outlet liquid temperature is the same as the minimum dew point, and heating is not stopped at the same time, resulting in frequent switching between heating and stopping, thereby causing system instability.

[0081] In this embodiment, for example, the first temperature margin is 2 degrees Celsius.

[0082] Step S205: monitor and obtain the outlet liquid temperature, determine that the outlet liquid temperature is greater than the sum of the minimum dew point, the first temperature margin and the first temperature threshold, and stop the heating process.

[0083] In this embodiment, during the heating process, the outlet liquid temperature is monitored, and when it is determined that the outlet liquid temperature is greater than the sum of the minimum dew point, the first temperature margin and the first temperature threshold, it is determined that condensation will not occur at this time, and the heating process is stopped.

[0084] In this embodiment, for example, the first temperature threshold is 0.5.

[0085] In this embodiment, the outlet liquid temperature, the temperature and humidity of multiple detection points are obtained; the dew points of multiple detection points are obtained according to the temperature and humidity of multiple detection points; the minimum dew point is obtained according to the dew points of multiple detection points; it is determined that the difference between the minimum dew point and the outlet liquid temperature is less than the first temperature margin, and the liquid in the liquid cooling device is heated; the outlet liquid temperature is obtained, and it is determined that the outlet liquid temperature is greater than the sum of the minimum dew point, the first temperature margin and the first temperature threshold, and the heating process is stopped. Compared with the prior art, the condensation generated by the liquid cooling device of the energy storage system wets the electrical components, causing the electrical components to short-circuit. , which leads to the technical problem that the energy storage system fails. The present application obtains the dew points of multiple detection points according to the temperatures and humidity of multiple detection points, and then obtains the minimum dew point according to the dew points of multiple detection points. When it is determined that the difference between the minimum dew point and the outlet liquid temperature is less than the first temperature margin, heating treatment is performed. During the heating process, the outlet liquid temperature is monitored and obtained, and when it is determined that the outlet liquid temperature is greater than the sum of the minimum dew point, the first temperature margin and the first temperature threshold, the heating treatment is stopped to achieve the avoidance of condensation while cooling the energy storage system, thereby ensuring the normal operation of the energy storage system.

[0086] Figure 3 1 is a flow chart of a second embodiment of an energy storage system anti-condensation control method provided in an embodiment of the present application. Figure 3 As shown, specifically, after step S205, the method further includes:

[0087] Step S301: determine that the liquid outlet temperature is greater than the sum of the minimum dew point, the first temperature margin and the second temperature threshold, and perform refrigeration processing.

[0088] In this embodiment, after the heating process is stopped, the heat emitted by the energy storage system is transferred to the liquid, and the liquid temperature will continue to increase. In order to ensure the heat dissipation effect, when the liquid outlet temperature is greater than the sum of the minimum dew point, the first temperature margin and the second temperature threshold, the coolant is refrigerated. At this time, it can be ensured that the temperature of the coolant is between the sum of the minimum dew point, the first temperature margin and the first temperature threshold and the sum of the minimum dew point, the first temperature margin and the second temperature threshold.

[0089] In this embodiment, the second temperature threshold is greater than the first temperature threshold.

[0090] In this embodiment, for example, the second temperature threshold is 1.5.

[0091] In this embodiment, the liquid outlet temperature, the temperature and humidity of multiple detection points are obtained; the dew points of the multiple detection points are obtained according to the temperature and humidity of the multiple detection points; the minimum dew point is obtained according to the dew points of the multiple detection points; it is determined that the difference between the minimum dew point and the liquid outlet temperature is less than the first temperature margin, and the liquid in the liquid cooling device is heated; the liquid outlet temperature is obtained, and it is determined that the liquid outlet temperature is greater than the sum of the minimum dew point, the first temperature margin and the first temperature threshold, and the heating process is stopped; it is determined that the liquid outlet temperature is greater than the sum of the minimum dew point, the first temperature margin and the second temperature threshold, and refrigeration is performed to achieve heat dissipation of the energy storage system without generating condensation.

[0092] Figure 4 1 is a flow chart of a third embodiment of an energy storage system anti-condensation control method provided in an embodiment of the present application. Figure 4 Specifically, after step S201, the method further includes:

[0093] Step S401: Acquire external temperature and humidity.

[0094] In this embodiment, a temperature and humidity sensor is provided outside the energy storage system to collect the temperature and humidity of the external environment of the energy storage system.

[0095] Step S402: Obtain the external dew point according to the external temperature and humidity.

[0096] In this embodiment, the external temperature and humidity are substituted into the above formula 1 to obtain the external dew point.

[0097] Step S403: generating different levels of warning information according to the relationship between the external dew point, the outlet liquid temperature, and the second temperature margin.

[0098] In this embodiment, different levels of warning information are obtained according to the relationship between the external dew point, the outlet liquid temperature, and the second temperature margin.

[0099] In this embodiment, the different levels of warning information may be general warning information and serious warning information.

[0100] Step S404: Send different levels of warning information to the user terminal.

[0101] In this embodiment, different levels of alarm information are sent to the user terminal, and the user can perform different processing according to different alarm information.

[0102] In this embodiment, for example, if the alarm information is a general alarm information, maintenance personnel cannot open the door of the energy storage system unless it is an emergency; if the alarm information is a serious alarm information, maintenance personnel are strictly prohibited from opening the door of the energy storage system.

[0103] In this embodiment, the liquid outlet temperature, the temperature and humidity of multiple detection points are obtained; the external temperature and humidity are obtained; the external dew point is obtained according to the external temperature and humidity; different levels of alarm information are generated according to the relationship between the external dew point, the liquid outlet temperature, and the second temperature margin; the alarm information of different levels is sent to the user terminal to inform the user of the risk of condensation generation in the energy storage system to avoid condensation caused by user misoperation.

[0104] Figure 5 1 is a flow chart of a fourth embodiment of an energy storage system anti-condensation control method provided in an embodiment of the present application. Figure 5 As shown, specifically, one implementation of step S403 is:

[0105] Step S501: If it is determined that the liquid outlet temperature is less than and / or equal to the sum of the external dew point and the second temperature margin, a serious alarm message is generated.

[0106] In this embodiment, when it is determined that the liquid outlet temperature is less than and / or equal to the sum of the external dew point and the second temperature margin, after the door of the energy storage system is opened, condensation is easily generated after the external air enters the energy storage system, and a serious alarm message is generated at this time.

[0107] Step S502: If it is determined that the outlet liquid temperature is greater than the sum of the external dew point and the second temperature margin, and the outlet liquid temperature is less than and\or equal to the external dew point and the preset multiple of the second temperature margin, a general alarm message is generated.

[0108] In this embodiment, if it is determined that the liquid outlet temperature is greater than the sum of the external dew point and the second temperature margin, and the liquid outlet temperature is less than and / or equal to the external dew point and a preset multiple of the second temperature margin, condensation may occur. At this time, a general alarm message will be generated to remind the user to pay attention.

[0109] In this embodiment, for example, the preset multiple may be 2.

[0110] In this embodiment, if it is determined that the liquid outlet temperature is less than and / or equal to the sum of the external dew point and the second temperature margin, a serious alarm message is generated; if it is determined that the liquid outlet temperature is greater than the sum of the external dew point and the second temperature margin, and the liquid outlet temperature is less than and / or equal to the external dew point and a preset multiple of the second temperature margin, a general alarm message is generated to remind the user to take action to avoid condensation caused by human factors.

[0111] Figure 6 FIG. 1 is a flow chart of a fifth embodiment of an energy storage system anti-condensation control method provided in an embodiment of the present application. Figure 6 As shown, specifically, in step S204, one implementation method of heating the liquid in the liquid cooling device is:

[0112] Step S601: obtaining a set of temperature difference values ​​according to the temperatures and dew points of multiple detection points.

[0113] In this embodiment, the temperature of each detection point is subtracted from the dew point corresponding to the detection point to obtain a temperature difference value corresponding to each detection point, and the temperature difference value corresponding to each detection point constitutes a temperature difference value set.

[0114] Step S602: Determine whether the temperature difference value in the temperature difference value set is greater than a preset temperature.

[0115] In this embodiment, the temperature difference values ​​in the temperature difference value set are compared with the preset temperatures respectively.

[0116] In this embodiment, for example, the preset temperature may be 3 degrees Celsius.

[0117] Step S603: If it is determined that the temperature difference value in the temperature difference value set is greater than the preset temperature, the detection point corresponding to the temperature difference value is obtained.

[0118] In this embodiment, when calculating the temperature difference value, the temperature difference value has a corresponding relationship with the detection point. When it is determined that the temperature difference value is greater than the preset temperature, the detection point matching the temperature difference value is obtained from the corresponding relationship.

[0119] Step S604: heating the liquid in the liquid cooling device corresponding to the detection point.

[0120] In this embodiment, there are multiple liquid cooling devices in the energy storage system. When it is determined that the detection point needs to be heated, one or more liquid cooling devices corresponding to the detection point are matched according to the correspondence between the detection point and the liquid cooling device, and then the liquid in the one or more liquid cooling devices is heated by a fixed heating power.

[0121] In this embodiment, it is also possible to use Formula 2:

[0122]

[0123] The heating power P is obtained. Where k is the temperature control coefficient, ΔT is the temperature difference, P max is the maximum heating power, and k is the temperature control coefficient.

[0124] In this embodiment, for example, the temperature control coefficient is 0.2.

[0125] In this embodiment, a temperature difference value set is obtained based on the temperatures and dew points of multiple detection points; it is determined whether the temperature difference value in the temperature difference value set is greater than the preset temperature; if it is determined that the temperature difference value in the temperature difference value set is greater than the preset temperature, the detection point corresponding to the temperature difference value is obtained; the liquid in the liquid cooling device corresponding to the detection point is heated, thereby preventing condensation from occurring while ensuring normal heat dissipation at other locations of the energy storage system.

[0126] Figure 7 1 is a flow chart of a sixth embodiment of an energy storage system anti-condensation control method provided in an embodiment of the present application. Figure 7 As shown, after step S205, the method further includes:

[0127] Step S701: Obtain energy storage system fault information.

[0128] In this embodiment, the energy storage system fault information includes insulation fault, liquid cooling system fault, over-temperature fault, etc.

[0129] Step S702: Obtain the level of the energy storage system fault information according to the energy storage system fault information.

[0130] In this embodiment, a correspondence relationship between energy storage system fault information and levels is preset, and the level corresponding to the energy storage system fault information is obtained from the correspondence relationship.

[0131] Step S703: If it is determined that the level of the energy storage system fault information is serious, the heating process is stopped.

[0132] In this embodiment, for example, the level corresponding to the temperature being too high is severe, and the heating process needs to be stopped at this time.

[0133] In this embodiment, energy storage system fault information is obtained; based on the energy storage system fault information, the level of the energy storage system fault information is obtained; if the level of the energy storage system fault information is determined to be serious, the heating process is stopped, thereby ensuring the normal operation of the energy storage system.

[0134] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effect of the present application, different steps do not have to be executed in such an order. They can be executed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present application.
