[0049] In the following description, specific details such as specific system structures and technologies are provided for illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the embodiments of the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the embodiments of the present application.

[0050] It should be noted that although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown in the flowcharts. The terms "first," "second," and the like in the specification, claims, and drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0051] It should also be understood that references to "one embodiment" or "some embodiments" described in the description of the embodiments of the present application mean that one or more embodiments of the embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Thus, the phrases "in one embodiment," "in some embodiments," "in some other embodiments," "in some other embodiments," etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and their variations all mean "including but not limited to," unless otherwise specifically emphasized.

[0052] Containerized energy storage systems integrate a central control cabinet, battery modules, and fire protection systems, offering advantages such as ease of transportation and installation. Currently, most containerized energy storage systems are deployed in regions with harsh climates. When the external climate fluctuates dramatically, humidity is high, and temperatures drop significantly, condensation can easily form in low-temperature areas within the energy storage system. This can cause short circuits at internal cable connections, electrical components within the control box, or at the positive and negative electrodes of the battery cells, disrupting the normal operation of the battery modules.

[0053] To reduce condensation within energy storage systems, a large amount of desiccant is typically placed inside containerized energy storage systems. The desiccant absorbs moisture from the air inside the system. However, in practice, containers are not completely sealed, allowing humid air from outside to enter through gaps within the container. The desiccant continuously absorbs moisture from the air, and when the desiccant reaches saturation, it loses its effectiveness. Because the moisture inside the container is not drained, when the temperature inside the container rises, the moisture inside the desiccant evaporates and returns to the air, potentially disrupting the normal operation of the energy storage system's modules.

[0054] Based on this, the embodiments of the present application provide a control method and device, and a storage medium for a container-type energy storage system, which can control the operation and stop of the dehumidification module, battery module, and heating module through the difference between the battery module temperature, the low-temperature area temperature, and the internal dew point temperature, thereby reducing the relative humidity of the environment, increasing the low-temperature area temperature and the battery module temperature, and reducing the risk of internal condensation.

[0055] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0056] Reference Figure 1 , Figure 1: is a schematic diagram of a containerized energy storage system provided in an embodiment of the present application. The containerized energy storage system includes a sampling module, a heating module, a battery module, and an air conditioning module, wherein the sampling module is used to obtain the internal ambient temperature, ambient relative humidity, battery module temperature, and low-temperature zone temperature of the energy storage system; the heating module is used to increase the temperature within the energy storage system; the air conditioning module includes a heating mode and a dehumidification mode, and the air conditioning module can reduce the humidity within the energy storage system through the dehumidification mode. After the sampling module obtains the internal ambient temperature, ambient relative humidity, battery module temperature, and low-temperature zone temperature of the energy storage system, it transmits the relevant data to the control device of the containerized energy storage system for processing. The control device of the containerized energy storage system controls the heating module, battery module, and air conditioning module according to the data collected by the sampling module to adjust the internal ambient temperature, ambient relative humidity, battery module temperature, and low-temperature zone temperature of the energy storage system.

[0057] It should be noted that the functions of one or more modules in the energy storage system of the present application can be implemented by a single physical device. For example, the functions of the heating module and the sampling module can be implemented by one device.

[0058] It should be noted that the control method and device of the containerized energy storage system of the embodiment of the present application are not limited to a few modules, and can be added on the basis of existing ones.

[0059] Reference Figure 2 , Figure 2 This is a control device for a containerized energy storage system provided in an embodiment of the present application. The control device is communicatively connected to the containerized energy storage system, which includes a sampling module, a heating module, a dehumidification module, and a battery module. The control device includes a data acquisition unit 100, a dew point calculation unit 200, and a mode adjustment unit 300.

[0060] Among them, the data acquisition unit 100 is communicated with the dew point calculation unit 200 and the mode adjustment unit 300 respectively. The data acquisition unit 100 obtains the internal ambient temperature, ambient relative humidity, battery module temperature and low-temperature sampling area of ​​the energy storage system, and sends the obtained temperature value and humidity value to the dew point calculation unit 200 and the mode adjustment unit 300 respectively.

[0061] The dew point calculation unit 200 obtains the internal dew point temperature of the energy storage system according to the received internal ambient temperature and ambient relative humidity, and sends the internal dew point temperature to the mode adjustment unit 300 .

[0062] The mode adjustment unit 300 is respectively connected to the data acquisition unit 100 and the dew point calculation unit 200 for communication. The mode adjustment unit 300 calculates the difference between the battery module temperature, the low temperature area temperature and the internal dew point temperature, and controls the humidity and temperature in the energy storage system according to the calculation results, and determines whether to adjust the working mode of the battery module.

[0063] It should be noted that the control device of the containerized energy storage system provided in the embodiment of the present application includes a data acquisition unit 100, a dew point calculation unit 200, and a mode adjustment unit 300. The data acquisition unit 100, the dew point calculation unit 200, and the mode adjustment unit 300 are connected to each other in communication. First, the data acquisition unit 100 obtains the internal ambient temperature, ambient relative humidity, battery module temperature, and low temperature area temperature of the energy storage system, and sends the obtained temperature values ​​to the dew point calculation unit 200 and the mode adjustment unit 300 respectively. The dew point calculation unit 200 obtains the internal dew point temperature of the energy storage system based on the internal ambient temperature and ambient relative humidity from the data acquisition unit 100, and sends the internal dew point temperature to the mode adjustment unit 300. The mode adjustment unit 300 calculates the difference between the battery module temperature, the low temperature area temperature, and the internal dew point temperature based on the received temperature value, and controls the humidity and temperature in the energy storage system according to the calculation results, and determines whether to adjust the working mode of the battery module. The control device controls the humidity and temperature within the energy storage system and the operation of the battery modules by measuring the difference between the battery module temperature, the low-temperature area temperature, and the internal dew point temperature. This reduces the relative humidity of the environment, increases the low-temperature area temperature and the battery module temperature, and reduces the risk of internal condensation, making the operation of the containerized energy storage system safer and more reliable.

[0064] The devices and application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Those skilled in the art will appreciate that with the evolution of system architecture and the emergence of new application scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

[0065] It will be understood by those skilled in the art that Figure 2 The device structure shown in the figure does not constitute a limitation on the embodiments of the present application, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0066] exist Figure 2 In the device structure shown, each module can respectively call its stored target tracking program to execute the target tracking method.

[0067] Based on the above device, various embodiments of the control method of the containerized energy storage system of the embodiment of the present application are proposed.

[0068] Reference Figure 3 , Figure 3 This is a diagram of the main steps of the control method of the containerized energy storage system provided in the embodiment of the present application. The control method includes:

[0069] Step S100: Acquire the internal ambient temperature, ambient relative humidity, battery module temperature, and low-temperature area temperature of the energy storage system.

[0070] Step S200: Obtain the internal dew point temperature of the energy storage system according to the internal ambient temperature and ambient relative humidity.

[0071] Step S300: Calculate the difference between the battery module temperature, the low temperature area temperature, and the internal dew point temperature, and control the humidity and temperature in the energy storage system according to the calculation results and determine whether to adjust the working mode of the battery module.

[0072] It should be noted that containerized energy storage systems include multiple temperature and humidity monitoring devices, which are installed in various areas of the system to monitor the internal ambient temperature, relative humidity, battery module temperature, and low-temperature zone temperature. The low-temperature zone is the lowest temperature area within the container, typically the bottom of the container.

[0073] In step S100 of some embodiments, the internal ambient temperature of the energy storage system is the average temperature in the container or the average of the surface temperatures of each module, and the ambient relative humidity is the air humidity inside the container. Since the battery module includes multiple battery cells, the battery module temperature is the temperature of any collected battery cell, and the low-temperature area temperature is the lowest temperature in the container under the current circumstances. The sampling module collects each temperature value, which is beneficial to the subsequent control of the start and stop of each module through each temperature value. In addition, the real-time collection of the internal ambient temperature, ambient relative humidity, battery module temperature and low-temperature area temperature facilitates the acquisition of changes in various parameters in the container, which is beneficial to the subsequent adjustment and control of the working status of each module according to the relevant parameters.

[0074] It should be noted that the sampling module corresponding to the battery module temperature is the battery management unit, which is an electronic device that can monitor and manage the battery. It collects and calculates parameters such as voltage, current, temperature and SOC, and then controls the charging and discharging process of the current to protect and improve the battery.

[0075] In some embodiments, in step S200, the temperature at which the air is cooled to saturation while maintaining a constant water vapor content and constant air pressure is called the dew point temperature, or simply the dew point. This temperature is essentially the temperature at which water vapor and water reach equilibrium. When the surface temperature of an object is below the dew point, water vapor in the air condenses, producing condensation. When the surface temperature of an object is above the dew point, water vapor in the air does not condense. Therefore, calculating the internal dew point temperature facilitates subsequent temperature control of various module areas within the energy storage system, thereby reducing the occurrence of low-temperature condensation.

[0076] It should be noted that the dew point temperature can be calculated using the internal ambient temperature, ambient relative humidity, and current pressure, or can be obtained by querying a table corresponding to the internal ambient temperature, ambient relative humidity, and dew point temperature.

[0077] In step S300 of some embodiments, by calculating the difference between the battery module temperature, the low-temperature area temperature and the internal dew point temperature, it is determined whether condensation occurs in the current energy storage system, and based on the calculation results, the humidity and temperature in the energy storage system are controlled and it is determined whether the working mode of the battery module is adjusted to regulate the low-temperature area temperature and the battery module temperature.

[0078] It should be noted that the control method of the containerized energy storage system provided in the embodiment of the present application first obtains the internal ambient temperature, ambient relative humidity, battery module temperature and low temperature area temperature of the energy storage system, and calculates the internal dew point temperature of the energy storage system based on the internal ambient temperature and ambient relative humidity. Then, the difference between the battery module temperature, the low temperature area temperature and the internal dew point temperature is calculated, and the humidity and temperature in the energy storage system are controlled according to the calculation results, and it is determined whether to adjust the working mode of the battery module. The embodiment of the present application controls the humidity and temperature in the energy storage system and the operation of the battery module through the difference between the battery module temperature, the low temperature area temperature and the internal dew point temperature, reduces the ambient relative humidity, increases the low temperature area temperature and the battery module temperature, reduces the risk of internal condensation, and makes the operation of the containerized energy storage system safer and more reliable.

[0079] Reference Figure 4 , Figure 4 This is a step diagram of the mode adjustment of the control method of the containerized energy storage system provided in an embodiment of the present application. When the air conditioning module is in the standby state of the heating mode, step S300 includes but is not limited to the following steps:

[0080] Step S310: Calculate the difference between the battery module temperature and the internal dew point temperature to obtain a first difference.

[0081] Step S320: Calculate the difference between the low-temperature area temperature and the internal dew point temperature to obtain a second difference.

[0082] Step S330: Adjust the humidity in the energy storage system according to the first difference and the second difference to lower the internal dew point temperature.

[0083] Step S340: According to the first difference, the second difference, and a preset temperature threshold, the temperature in the energy storage system is adjusted and the battery module is controlled to be turned on.

[0084] In step S310 of some embodiments, the difference between the battery module temperature and the internal dew point temperature is calculated to obtain a first difference. The calculation of the first difference facilitates precise control of the battery module temperature, reduces the occurrence of positive and negative short circuits of the battery module due to condensation, and further improves the safety of the containerized energy storage system.

[0085] In step S320 of some embodiments, the second difference is calculated based on the difference between the low-temperature area temperature and the internal dew point temperature. The low-temperature area temperature is usually the lowest temperature in the containerized energy storage system. When the low-temperature area temperature meets the requirements, the temperatures of other areas in the container also meet the requirements.

[0086] In step S330 of some embodiments, the humidity within the energy storage system is adjusted by the first difference and the second difference to achieve the purpose of lowering the relative humidity of the environment, thereby lowering the internal dew point temperature. In addition, due to the decrease in the internal dew point temperature, the first difference and the second difference will also decrease synchronously.

[0087] In step S340 of some embodiments, the temperature within the energy storage system is adjusted and the battery module is controlled to be turned on based on the first difference, the second difference and the preset threshold condition, so as to increase the internal ambient temperature, the battery module temperature and the low-temperature area temperature, and reduce the first difference and the second difference.

[0088] It should be noted that the embodiment of the present application uses the difference between the battery module temperature and the internal dew point temperature as the first difference, and the difference between the low temperature area temperature and the internal dew point temperature as the second difference. First, the humidity in the energy storage system is adjusted according to the first difference and the second difference, so that the relative humidity of the environment is reduced, further reducing the internal dew point temperature. When the first difference and the second difference meet the requirements, the humidity in the energy storage system is no longer adjusted. Then, according to the first difference, the second difference and the preset threshold conditions, the temperature in the energy storage system is adjusted and the battery module is controlled to be turned on, so as to increase the internal environment temperature, the battery module temperature and the low temperature area temperature, so that the temperature of each module in the energy storage system meets the requirements. When the heating module of the air-conditioning module is turned on, the occurrence of condensation on the surface of each module due to temperature difference is reduced, thereby improving the safety of the energy storage system. The present application adjusts the internal environment temperature, the low temperature area temperature and the battery module temperature by adjusting both humidity and temperature so that the internal environment temperature, the low temperature area temperature and the battery module temperature are much higher than the internal dew point temperature to reduce the occurrence of condensation.

[0089] It should be noted that containerized energy storage systems are typically deployed in areas with harsh climates. When the ambient humidity is high and the temperature drops significantly, the air conditioning module in the energy storage system can provide heating. When the internal ambient temperature of the energy storage system is less than or equal to the preset activation temperature of the air conditioning module's heating mode, the air conditioning module is controlled to enter a standby state in heating mode. The temperature and humidity of the energy storage system are then adjusted to regulate the internal environment of the container and create favorable conditions for activation of the heating mode. When the temperature inside the container rises significantly, a significant temperature difference forms between the surfaces of other modules and the ambient temperature, resulting in condensation. The operations in steps S200 and S300 can further reduce the occurrence of condensation.

[0090] It should be noted that the preset opening temperature of the air-conditioning module can be adjusted according to actual conditions, and this embodiment does not impose any specific restrictions on the preset opening temperature.

[0091] It should be noted that the dehumidification module can be set up separately or integrated with the air-conditioning module. For example, a dehumidifier and other devices can be provided in the energy storage system to realize the dehumidification function, or an air conditioner can be provided in the energy storage system. The air conditioner can be used for heating and dehumidification, and the functions of the dehumidification module and the air-conditioning module are both realized through the air conditioner.

[0092] Reference Figure 5 , Figure 5 This is a diagram of the humidity control steps of the containerized energy storage system control method provided in the embodiment of the present application. Step S330 includes but is not limited to the following steps:

[0093] Step S331: When the first difference or the second difference is less than zero, control the energy storage system to start a dehumidification mode to lower the internal dew point temperature.

[0094] Step S332: When the first difference and the second difference are greater than or equal to zero, turn off the dehumidification mode.

[0095] It should be noted that when the first or second difference is less than zero, that is, when the battery module temperature is less than the internal dew point temperature or the low-temperature zone temperature is less than the dew point temperature, the energy storage system is controlled to activate dehumidification mode to reduce the relative humidity, thereby lowering the internal dew point temperature. When the dew point temperature drops below the battery module temperature and the low-temperature zone temperature, that is, when the first and second differences are greater than or equal to zero, the dehumidification mode is disabled. Steps S331 and S332 reduce the internal dew point temperature by lowering the relative humidity within the container.

[0096] Reference Figure 6 , Figure 6 This is a diagram of the temperature control steps of the containerized energy storage system control method provided in an embodiment of the present application. Step S340 includes but is not limited to the following steps:

[0097] Step S341: When the first difference is less than a preset first temperature threshold, the energy storage system is controlled to start a heating mode to increase the temperature of the low-temperature area.

[0098] Step S342: When the second difference is less than a preset second temperature threshold, control the battery module to charge and discharge to increase the temperature of the battery module.

[0099] In step S341 of some embodiments, when the first difference is less than a preset first temperature threshold, the energy storage system is controlled to start a heating mode until the first difference is greater than or equal to the preset first temperature threshold, so that the temperature of the low-temperature area and other areas of the containerized energy storage system meet the condition that no condensation occurs when the air-conditioning module heating mode is turned on.

[0100] In step S342 of some embodiments, to precisely control the temperature of the battery module, when the second difference is less than a preset second temperature threshold, the battery module is controlled to charge and discharge, so that the temperature of the battery module increases.

[0101] It should be noted that the preset first temperature threshold and the second temperature threshold may be equal or different, and their specific settings may be adjusted according to actual conditions.

[0102] It should be noted that the embodiment of the present application sequentially controls the energy storage system to turn on the heating mode and the battery module to charge and discharge, thereby increasing the temperature of each module in the container and reducing the temperature difference between the temperature of each module and the temperature in the air-conditioning heating mode, so that the temperature of each area of ​​the container meets the conditions for turning on the heating mode of the air-conditioning module, thereby reducing the occurrence of condensation.

[0103] Reference Figure 7 , Figure 7 This is a diagram of the steps of the heating control of the control method of the containerized energy storage system provided in the embodiment of the present application. The heating control is located after step S340, and the method includes but is not limited to the following steps:

[0104] Step S350: When both the first difference and the second difference are greater than the temperature threshold, the air conditioning module is controlled to turn on the heating mode.

[0105] It should be noted that, in combination with the above steps, when the first difference and the second threshold are both greater than the temperature threshold, the first difference is greater than or equal to the first threshold and the second difference is greater than or equal to the second threshold, that is, the temperature and humidity of each module area of ​​the containerized energy storage system meet the requirements, and the air-conditioning module is controlled to turn on the heating mode, thereby reducing the occurrence of damage to each module due to low temperature.

[0106] Reference Figure 8 , Figure 8This is another step diagram of the mode adjustment of the control method of the containerized energy storage system provided in the embodiment of the present application. When the battery module stops running, step S300 includes but is not limited to the following steps:

[0107] Step S360: When the temperature difference between the low-temperature area and the internal dew point temperature is less than a preset third threshold, the energy storage system is controlled to start the heating mode and the dehumidification mode.

[0108] Step S370: When the temperature difference between the low-temperature area and the internal dew point temperature is greater than or equal to a third threshold, the energy storage system is controlled to turn off the heating mode and the dehumidification mode.

[0109] It should be noted that when the battery module stops operating, if the outside temperature is too low, the surface temperature of the modules inside the containerized energy storage system drops faster than the temperature of the internal environment. The sharp drop in the internal environment temperature will cause moist air from the outside to enter the container, increasing the relative humidity of the environment. At this time, the temperature of each module is very likely to be lower than the internal dew point temperature. In addition, since the battery module has just stopped working, its temperature is high enough, and only the temperature of the internal environment and the low-temperature area need to be increased. First, the difference between the low-temperature area and the internal dew point temperature is calculated. When the difference between the low-temperature area and the internal dew point temperature is less than the preset third threshold, the energy storage system is controlled to turn on the heating mode and the dehumidification mode. While increasing the temperature of the internal environment and the low-temperature area, the relative humidity of the environment is reduced until the difference between the low-temperature area and the internal dew point temperature is greater than or equal to the third threshold. The energy storage system is controlled to turn off the heating mode and the dehumidification mode to reduce condensation caused by the sharp drop in the internal environment temperature.

[0110] Reference Figure 9 , Figure 9 This is a diagram of the steps of the control method for the containerized energy storage system provided in the embodiment of the present application. The method is located after step S300 and includes but is not limited to the following steps:

[0111] Step S400: When the internal ambient temperature and the low temperature area temperature are greater than or equal to the temperature value at the previous moment, stop obtaining the ambient relative humidity, the battery module temperature, the low temperature area temperature, and adjusting the humidity and temperature in the energy storage system and the operating mode of the battery module.

[0112] It should be noted that when the internal ambient temperature and the low-temperature zone temperature are greater than or equal to the previous temperature value, that is, when the internal ambient temperature and the low-temperature zone temperature no longer decrease, the acquisition of the ambient relative humidity, battery module temperature, and low-temperature zone temperature, as well as the adjustment of the humidity and temperature within the energy storage system and the adjustment of the battery module operating mode, are stopped. At this time, the internal ambient temperature is collected in real time, and when the internal ambient temperature is lower than the preset activation temperature of the air conditioning module, the heating mode of the air conditioning module is controlled to be turned on.

[0113] It should be noted that the control method of the containerized energy storage system provided in the embodiment of the present application is mainly divided into two stages. When the internal ambient temperature drops to the preset start-up temperature of the air-conditioning module, the air-conditioning module is controlled to be in standby state. First, the internal ambient temperature, ambient relative humidity, battery module temperature and low-temperature area temperature of the energy storage system are obtained, and the internal dew point temperature of the energy storage system is obtained according to the internal ambient temperature and ambient relative humidity. Finally, the dehumidification mode is turned on and off according to the difference between the battery module temperature, the low-temperature area temperature and the internal dew point temperature to lower the internal dew point temperature, and the difference is compared with the preset threshold condition to control the opening of the heating module and the adjustment of the working mode of the battery module. When the battery module temperature and the low-temperature area temperature meet the conditions, the air-conditioning module is controlled to turn on the heating mode. When the battery system is turned off, that is, the heating mode of the air conditioner is turned off, the difference between the low-temperature area and the internal dew point temperature is calculated. When the difference is less than the preset threshold, the heating mode and the dehumidification mode are controlled to be turned on. While increasing the ambient temperature and the low-temperature area temperature in the box, the relative humidity of the environment is reduced until the third difference is greater than or equal to the third threshold. The heating module and the dehumidification module are controlled to be turned off to reduce the condensation caused by the sharp drop in the internal ambient temperature. When the internal ambient temperature and the low-temperature area temperature are greater than or equal to the temperature value at the previous moment, that is, the ambient temperature and the low-temperature area temperature in the box no longer drop, the acquisition of the relative humidity of the environment, the battery module temperature, the low-temperature area temperature, and the adjustment of the humidity and temperature in the energy storage system and the adjustment of the working mode of the battery module are stopped. This application controls the humidity and temperature in the energy storage system and the operation of the battery module by the difference between the battery module temperature, the low-temperature area temperature and the internal dew point temperature, reduces the relative humidity of the environment, increases the low-temperature area temperature and the battery module temperature, reduces the risk of internal condensation, and makes the operation of the containerized energy storage system safer and more reliable.
