Technical Field

[0001] This invention relates to the field of energy storage technology, and in particular to a method, apparatus and system for controlling the operating environment of an energy storage system. Background Technology

[0002] Energy storage systems, especially large-scale battery energy storage systems comprising multiple battery energy storage units, are significantly affected by their operating environment in terms of safety, lifespan, and overall efficiency. Battery energy storage units generate substantial heat during charging and discharging, leading to increased internal system temperatures. Both excessively high and low temperatures can accelerate battery aging and potentially trigger serious safety incidents such as thermal runaway. Simultaneously, ambient humidity is another critical factor affecting the safe operation of energy storage systems. In high-humidity environments, condensation is prone to occur inside the energy storage system. This condensation can cause short circuits in electrical components, corrosion of metal structures, and decreased insulation performance, thus posing serious safety hazards.

[0003] Currently, there are various temperature and humidity control schemes available for environmental control of energy storage systems. However, in most existing environmental control architectures of energy storage systems, the liquid temperature control unit and the dehumidification unit are usually regarded as two independent functional subsystems, each operating independently according to preset trigger conditions, resulting in poor coordination of environmental control of energy storage systems. Summary of the Invention

[0009] According to the present invention, an operating environment control method for an energy storage system, wherein activating the liquid temperature control unit includes: Based on the highest temperature and highest humidity values ​​of the energy storage system, the outlet water temperature value of the liquid temperature control unit is determined to activate the liquid temperature control unit.

[0010] According to the present invention, an operating environment control method for an energy storage system, wherein activating the liquid temperature control unit includes: If the outlet water temperature value is within the preset outlet water temperature range, the liquid temperature control unit is activated based on the outlet water temperature value. If the outlet water temperature value is less than the lowest outlet water temperature in the outlet water temperature range, the liquid temperature control unit is activated based on the lowest outlet water temperature. If the outlet water temperature value is greater than the highest outlet water temperature in the outlet water temperature range, the liquid temperature control unit is activated based on the highest outlet water temperature.

[0011] According to the operating environment control method of an energy storage system provided by the present invention, after starting the liquid temperature control unit, the method further includes: If the outlet water temperature value is not greater than the correction temperature value, then the dehumidification unit is activated, and the outlet water temperature value is adjusted within the outlet water temperature range; wherein, the correction temperature value is obtained based on the highest temperature value and the preset temperature difference.

[0012] According to the operating environment control method of an energy storage system provided by the present invention, after starting the liquid temperature control unit, the method further includes: If the outlet water temperature is greater than the correction temperature value, and the highest humidity value of the energy storage system is greater than the preset lowest humidity value, then the dehumidifier is started, and the outlet water temperature is adjusted within the specified range.

[0013] The present invention also provides an operating environment control device for an energy storage system, the energy storage system comprising at least two battery energy storage units, a liquid temperature control unit, and a dehumidification unit, the device comprising: A temperature determination module is used to acquire the real-time temperature of the battery energy storage unit and determine the average temperature of at least two of the battery energy storage units based on the real-time temperature. A liquid temperature control module is used to determine to activate the liquid temperature control unit when the average temperature is greater than a preset temperature value; A humidity control module is used to determine not to start the dehumidification unit when the average temperature is greater than the highest temperature value of the energy storage system.

[0022] Figure 3 This is a schematic diagram of the operating environment control device for the energy storage system provided by the present invention.

[0023] Figure 4 This is a schematic diagram of the physical structure of the electronic device provided by the present invention. Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0025] Environmental control of energy storage systems is crucial for ensuring the safety, lifespan, and overall efficiency of battery energy storage units. Currently, a coordinated approach is commonly used, primarily employing condensation dehumidification supplemented by intelligent ventilation. This prioritizes zero-energy ventilation using dry outdoor air, only activating high-efficiency dehumidification equipment when necessary to reduce dehumidification energy consumption, while ensuring absolute condensation prevention. The coordinated control logic optimizes equipment operation by predicting external environmental conditions and battery load, thereby reducing overall energy consumption while ensuring the safety and lifespan of the battery energy storage units.

[0026] However, in a synergistic mode where condensation dehumidification is the primary method and intelligent ventilation is secondary, a large proportion of the energy consumption of the equipment itself is supplemented by the auxiliary energy consumption of the energy storage power station. For example, air conditioners dehumidify while cooling, but excessive cooling and reheating processes waste a lot of energy, resulting in low overall energy efficiency. Furthermore, advanced liquid cooling and precision dehumidification systems have complex structures. The intricate piping, pumps, valves, and control systems increase the risk of failure and leakage. Advanced liquid cooling and precision dehumidification systems require extremely high levels of expertise in design, installation, and operation and maintenance, leading to high initial investment and maintenance costs.

[0027] To provide a stable and suitable operating environment for the battery energy storage unit, and to reduce the energy consumption of the environmental control system, the liquid temperature control unit and dehumidification unit are integrated into a single system. Based on real-time temperature and humidity data, dynamic decisions are made to jointly control temperature and dehumidification. The following section combines... Figures 1 to 4 The present invention describes the operating environment control method, apparatus and system of the energy storage system.

[0028] The energy storage system includes at least two battery energy storage units, a liquid temperature control unit, and a dehumidification unit. The liquid temperature control unit and the dehumidification unit can be interconnected through a collaborative control unit. The operating environment control method for the energy storage system provided by this invention can be applied to the collaborative control unit to achieve joint control of the liquid temperature control unit and the dehumidification unit, providing a stable and suitable operating environment for the battery energy storage units.

[0029] The control unit can also be called a control unit, system control unit, etc. The energy storage system can be a closed liquid-cooled system such as an electric vehicle or energy storage power station. The liquid temperature control unit can be a liquid-cooled main unit, and the dehumidification unit can be a dehumidifier.

[0030] Figure 1 This is a flowchart illustrating the operating environment control method for the energy storage system provided by the present invention, as shown below. Figure 1 As shown, the method includes the following steps.

[0031] Step 101: Obtain the real-time temperature of the battery energy storage unit, and determine the average temperature of at least two of the battery energy storage units based on the real-time temperature.

[0032] It should be noted that, as Figure 2 As shown, the energy storage system may also include a temperature sampling unit. The temperature sampling unit, liquid temperature control unit, and dehumidification unit are respectively connected to the collaborative control unit. The real-time temperature of the battery energy storage unit can be collected through the temperature sampling unit, and the real-time temperature of each battery energy storage unit can be sent to the collaborative control unit to summarize the real-time temperatures of each battery energy storage unit and calculate the average temperature of at least two battery energy storage units, so as to facilitate the subsequent control of the liquid temperature control unit and the dehumidification unit.

[0033] The temperature sampling unit can also be called a temperature sampling module, and the collaborative control unit can also be called a collaborative control module. In this embodiment, no such limitation is made.

[0034] For example, the real-time temperature of the battery storage unit can be the real-time temperature of the battery cell.

[0035] Step 102: When the average temperature is greater than the preset temperature value, determine to start the liquid temperature control unit.

[0036] The preset temperature value is a pre-set temperature threshold for determining whether cooling is required. For example, if the average temperature is not greater than the preset temperature value, the liquid temperature control unit will not be activated.

[0037] It should be noted that the specific value of the preset temperature can be set according to the actual working conditions, and this embodiment does not limit it.

[0038] Understandably, by comparing the average temperature of at least two battery energy storage units with the preset temperature value, it is possible to determine whether to activate the liquid temperature control unit. This can prevent frequent false activation of the liquid temperature control unit caused by local disturbances in a certain battery energy storage unit, thereby reducing ineffective energy consumption.

[0039] For example, a battery energy storage unit may experience high temperatures due to instantaneous operating conditions or uneven local heat dissipation, which may cause local disturbances with artificially high temperatures.

[0040] Step 103: When the average temperature is greater than the highest temperature value of the energy storage system, determine that the dehumidification unit will not be started.

[0041] It should be noted that the temperature value of the current operating environment of the energy storage system can be collected by the liquid temperature control unit and / or dehumidification unit and transmitted to the collaborative control unit in real time, so as to filter and determine the highest temperature value of the current operating environment of the energy storage system from the sampled temperature values ​​at various locations.

[0042] The energy storage system operation environment control method provided in this invention acquires the real-time temperature of the battery energy storage units, determines the average temperature of at least two battery energy storage units based on the real-time temperature, and activates the liquid temperature control unit when the average temperature is greater than a preset temperature value, and deactivates the dehumidification unit when the average temperature is greater than the highest temperature value of the energy storage system. Therefore, by comparing the average temperature with the preset temperature value and the highest temperature value in stages, the liquid temperature control unit and the dehumidification unit can be dynamically and collaboratively controlled based on the real-time temperature, thereby improving the synergy of the energy storage system's environmental control and reducing the risk of additional heat generation or overcooling.

[0043] It is understandable that controlling the working status of the liquid temperature control unit and the dehumidification unit at the same time can control the humidity of the operating environment of the energy storage system, reduce the risk of condensation, and thus reduce the total energy consumption of the liquid temperature control unit and the dehumidification unit while maintaining the insulation performance of the air in the operating environment of the energy storage system.

[0044] Meanwhile, by coordinating the control of the liquid temperature control unit and the dehumidification unit, a stable and suitable operating environment can be provided for the battery energy storage unit, thereby delaying the capacity decay of the battery energy storage unit and extending its service life, thus fundamentally improving the overall energy efficiency of the energy storage system and optimizing its operating costs.

[0045] Based on the above embodiments, the preset temperature value includes a first set temperature; Activating the liquid temperature control unit when the average temperature is greater than a preset temperature value includes: if the energy storage system is not in the process of charging or discharging, then activating the liquid temperature control unit when the average temperature is greater than the first set temperature.

[0046] The first set temperature is a pre-set temperature threshold used to determine whether cooling is required when the energy storage system is not in the process of charging or discharging.

[0047] It should be noted that if the collaborative control module detects that the energy storage system is not in the process of charging or discharging, it will obtain the average temperature T of the battery energy storage unit. cell The average temperature T of the battery energy storage unit cell Compare with the first set temperature T1 to determine whether T is met. cell If ≥T1, then start the liquid cooling unit.

[0048] Based on the above embodiments, the preset temperature value includes a second set temperature; Activating the liquid temperature control unit when the average temperature is greater than a preset temperature value includes: if the energy storage system is in the process of charging or discharging, then activating the liquid temperature control unit when the average temperature is greater than the second set temperature.

[0049] The first set temperature is a pre-set temperature threshold used by the energy storage system to determine whether cooling is required during the charging and discharging process.

[0050] It should be noted that if the collaborative control module detects that the energy storage system is in the charging and discharging process, it will obtain the average temperature T of the battery energy storage unit. cell The average temperature T of the battery energy storage unit cell Compare with the second set temperature T2 to determine whether T is met. cell If ≥T2, then start the liquid cooling unit.

[0051] It is understandable that the thermal load characteristics of the battery energy storage unit during the charging and discharging process are different from those during the non-charging and discharging process. In this embodiment, the charging and discharging signal is detected to determine whether the energy storage system is in the charging and discharging process. If it is not in the charging and discharging process, the liquid temperature control unit is activated based on the average temperature and the first set temperature. If it is in the charging and discharging process, the liquid temperature control unit is activated based on the average temperature and the second set temperature. This can activate the liquid temperature control unit in a timely manner during the charging and discharging phase to prevent the temperature from exceeding the limit, while avoiding the premature activation of the liquid temperature control unit during the non-charging and discharging phase. This not only slows down the capacity decay of the battery energy storage unit and extends its service life, but also reduces auxiliary energy consumption.

[0052] Based on any of the above embodiments, the method further includes: if the energy storage system is not in the process of charging or discharging, then when the average temperature is not greater than the highest temperature value of the energy storage system, determining to start the dehumidification unit.

[0053] It should be noted that the energy storage system is not in the charging / discharging process, and the average temperature T of the battery energy storage unit is... cell Compared with the first set temperature T1, it does not meet the T... cell When T1 is greater than or equal to T1, the average temperature T of the battery energy storage unit can be further increased. cell The highest temperature value T of the operating environment of the energy storage system airMax Compare and determine whether T is satisfied. cell ≥T airMax If otherwise, the dehumidification unit will be activated; otherwise, it will not be activated.

[0054] In some embodiments, the average temperature T of the battery energy storage unit cell The highest temperature value T of the operating environment of the energy storage system airMax By comparison, it was determined that when starting the dehumidification unit, it can be started at low power, or only one dehumidification unit can be started.

[0055] Based on any of the above embodiments, the method further includes: if the energy storage system is in the process of charging and discharging, then when the average temperature is not greater than the corrected temperature value of the energy storage system, the dehumidification unit is determined to be started.

[0056] The corrected temperature value is obtained based on the highest temperature value and the preset temperature difference.

[0057] In some embodiments, the preset temperature difference is 3°C, and the correction temperature value is taken as the highest temperature value T. airMax -3℃.

[0058] It should be noted that the energy storage system is not in the charging / discharging process, and the average temperature T of the battery energy storage unit is... cell Compared with the second set temperature T2, it does not meet the T2 requirement. cell When T2 is greater than or equal to T2, the average temperature T of the battery energy storage unit can be further increased. cell Corrected temperature value T for the operating environment of the energy storage system airMax Compare with -3℃ to determine if T is met. cell ≤T airMax If the temperature is -3℃, the dehumidification unit will be activated.

[0059] In some embodiments, if T is not satisfied cell ≤T airMax The dehumidification unit will not start if the temperature is -3℃.

[0060] In some embodiments, the average temperature T of the battery energy storage unit cell The highest temperature value T of the operating environment of the energy storage system airMax By comparing the temperature to -3℃, it was determined that when starting the dehumidification unit, it can be started at low power, or only one dehumidification unit can be started.

[0061] It is understandable that the thermal load characteristics of the battery energy storage unit during the charging and discharging process are different from those during the non-charging and discharging process. In this embodiment, the charging and discharging signal is detected to determine whether the energy storage system is in the charging and discharging process. If it is not in the charging and discharging process, the dehumidification unit is activated based on the average temperature and the highest temperature value. If it is in the charging and discharging process, the dehumidification unit is activated based on the average temperature and the corrected temperature value. This can activate the dehumidification unit in a timely manner during the charging and discharging stage to reduce the risk of condensation. At the same time, it avoids the dehumidification unit from activating too early during the non-charging and discharging stage. This slows down the capacity decay of the battery energy storage unit, extends the service life of the battery energy storage unit, and reduces auxiliary energy consumption.

[0062] It should be noted that the above judgment on whether to start the dehumidification unit can be performed after determining whether to start the liquid temperature control unit; the following monitoring judgment can be performed after starting the dehumidifier.

[0063] Based on any of the above embodiments, the energy storage system includes at least two of the dehumidification units; After activating the dehumidification unit, the method further includes: Monitor the real-time humidity value of the energy storage system, and shut down the dehumidification unit when the real-time humidity value is not greater than the preset minimum humidity value; or Monitor the real-time humidity value of the energy storage system, and activate at least two dehumidification units when the real-time humidity value is greater than the preset minimum humidity value.

[0064] Among them, the preset minimum humidity value RH 额定 It is the preset target lower limit for relative humidity, which is the safe threshold that the air humidity of the operating environment of the energy storage system is allowed to reach.

[0065] It should be noted that after the dehumidification unit is started, the humidity value of the current operating environment of the energy storage system can be collected through the liquid temperature control unit and / or the dehumidification unit, and transmitted to the collaborative control unit in real time, so as to filter and determine the highest humidity value of the current operating environment of the energy storage system from the humidity values ​​of various locations.

[0066] The highest humidity value (RH) that can be monitored Max With the preset minimum humidity value RH 额定 Compare and determine if RH is met. 额定 ≥RH Max If so, shut down the dehumidification unit; otherwise, start at least two dehumidification units, or gradually increase the dehumidification power through the coordination control unit until the highest humidity value (RH) detected is reached. Max With the preset minimum humidity value RH 额定 Compare and determine if RH is met. 额定 ≥RH Max Turn off the dehumidifier unit.

[0067] In some embodiments, the humidity value of the current operating environment of the energy storage system can be collected at preset time intervals by a liquid temperature control unit and / or a dehumidification unit, and the highest humidity value RH detected can be recorded. Max Compare with the preset minimum humidity rating (RH) to determine if the RH requirement is met. 额定 ≥RH Max .

[0068] Based on any of the above embodiments, activating the liquid temperature control unit includes: Based on the highest temperature and highest humidity values ​​of the energy storage system, the outlet water temperature value of the liquid temperature control unit is determined to activate the liquid temperature control unit.

[0069] It should be noted that the humidity value of the current operating environment of the energy storage system can be collected by the liquid temperature control unit and / or dehumidification unit and transmitted to the collaborative control unit in real time, so as to filter and determine the highest humidity value of the current operating environment of the energy storage system from the humidity values ​​of various locations.

[0070] In some embodiments, the outlet water temperature of the liquid temperature control unit can be calculated using the following formula: T water =T d =T airMax -(100-RH Max / 5); Among them, T d It is the dew point temperature value.

[0071] Understandably, by calculating the dew point temperature in real time using the highest ambient temperature and highest relative humidity values ​​inside the battery compartment, and setting the liquid cooling unit's outlet water temperature to this dew point temperature, the liquid cooling temperature control unit can operate at a higher outlet water temperature as much as possible while meeting anti-condensation requirements. This avoids excessive cooling due to excessively low outlet water temperatures, reduces the auxiliary energy consumption of the liquid cooling unit, and prevents condensation from forming on pipes or heat exchange surfaces due to temperatures below the dew point. This ensures the air insulation performance inside the battery compartment and extends the service life of the battery energy storage unit.

[0072] It should be noted that the outlet water temperature value T can be... water With the lowest outlet water temperature T waterMin Maximum outlet water temperature T waterMax Compare and determine whether T is satisfied. waterMin ≤T water ≤T waterMax This is to control the outlet water temperature of the liquid temperature control unit.

[0073] Specifically, activating the liquid temperature control unit includes: If the outlet water temperature value is within the preset outlet water temperature range, the liquid temperature control unit is activated based on the outlet water temperature value. If the outlet water temperature value is less than the lowest outlet water temperature in the outlet water temperature range, the liquid temperature control unit is activated based on the lowest outlet water temperature. If the outlet water temperature value is greater than the highest outlet water temperature in the outlet water temperature range, the liquid temperature control unit is activated based on the highest outlet water temperature.

[0074] Based on any of the above embodiments, after activating the liquid temperature control unit, the method further includes: If the outlet water temperature value is not greater than the correction temperature value, then the dehumidification unit is activated, and the outlet water temperature value is adjusted within the specified outlet water temperature range.

[0075] The corrected temperature value is obtained based on the highest temperature value and the preset temperature difference.

[0076] In this embodiment, the calculation method for the corrected temperature value is the same as that described above, and will not be repeated here.

[0077] It should be noted that after obtaining the corrected temperature value, it can be determined whether the outlet water temperature value is less than or equal to the corrected temperature value. If so, at least two dehumidification units will be started, or the dehumidification power will be gradually increased through the collaborative control unit until the outlet water temperature value is no longer less than or equal to the corrected temperature value.

[0078] Based on any of the above embodiments, after activating the liquid temperature control unit, the method further includes: If the outlet water temperature is greater than the correction temperature value, and the highest humidity value of the energy storage system is greater than the preset lowest humidity value, then the dehumidifier is started, and the outlet water temperature is adjusted within the specified range.

[0079] It should be noted that after starting the dehumidifier, the temperature value of the current operating environment of the energy storage system can be collected at preset time intervals through the liquid temperature control unit and / or the dehumidification unit, and the following steps can be repeated: Based on the highest temperature and highest humidity values ​​of the energy storage system, the outlet water temperature value of the liquid temperature control unit is determined. The outlet water temperature value T water With the lowest outlet water temperature T waterMin Maximum outlet water temperature T waterMax Compare and determine whether T is satisfied. waterMin ≤T water ≤T waterMax To control the outlet water temperature of the liquid temperature control unit; When the outlet water temperature is greater than the correction temperature, determine whether the RH requirement is met. 额定 ≥RH Max ; If not, repeat the above steps; if yes, turn off the dehumidifier unit. If the outlet water temperature is lower than the lowest outlet water temperature in the outlet water temperature range, the outlet water temperature value is updated based on the lowest outlet water temperature, and the liquid temperature control unit is activated based on the updated outlet water temperature value. Similarly, if the outlet water temperature is higher than the highest outlet water temperature in the outlet water temperature range, the outlet water temperature value is updated based on the highest outlet water temperature, and the liquid temperature control unit is activated based on the updated outlet water temperature value.

[0080] Based on this, it is determined whether the outlet water temperature value is less than or equal to the corrected temperature value. This could be the outlet water temperature value calculated using the formula above, or it could be the lowest or highest outlet water temperature within the preset water temperature range.

[0081] The operating environment control device for the energy storage system provided by the present invention is described below. The operating environment control device for the energy storage system described below can be referred to in correspondence with the operating environment control method for the energy storage system described above.

When the processor executes the computer program, it implements the operating environment control method of any of the above-described energy storage systems.

[0084] Figure 4 An example is a schematic diagram of the physical structure of an electronic device, such as... Figure 4 As shown, the electronic device may include a processor 410, a communications interface 420, a memory 430, and a communication bus 440. The processor 410, communications interface 420, and memory 430 communicate with each other via the communication bus 440. The processor 410 can call logical instructions in the memory 430 to execute an operating environment control method for the energy storage system.

[0085] Furthermore, the logical instructions in the aforementioned memory 430 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) to execute all or part of the steps of the methods described in the various embodiments of the present invention.
