Description

Technical Field

[0001] This invention relates to the field of liquid cooling control technology, specifically to a liquid cooling control method, device, equipment, and medium for a container dual-loop unit. Background Technology

[0002] The stable operation of energy storage systems is closely related to temperature control. Liquid cooling solutions, with their efficient heat dissipation capabilities, have become the mainstream technology choice for temperature control of energy storage containers and are widely used in various energy storage projects. As the core of the liquid cooling solution, the Thermal Management System (TMS) directly affects the operational safety, energy consumption level, and overall efficiency of the energy storage system due to the rationality of its control strategy.

[0003] Currently, most liquid cooling control strategies employ passive response control logic. Liquid cooling units rely solely on the inlet and outlet water temperatures of the liquid cooling circuit as the core control basis. When the water temperature exceeds a preset threshold, the operating power of cooling devices (such as compressors and heat exchangers) is activated or increased; conversely, the power is reduced or the system is shut down. The start and stop of heating devices are also based solely on whether the water temperature is below a set lower limit, lacking a comprehensive consideration of the overall system operating status. Relying solely on water temperature feedback for control is essentially a reactive measure to address an already occurring temperature rise, failing to predict heating trends in advance. This leads to a lag in temperature control response, potentially resulting in localized overheating and impacting the lifespan of core components such as batteries and PCS. To avoid temperature runaway, traditional strategies often require the continuous operation of core components such as compressors and heat exchangers for extended periods, resulting in significant energy waste and reducing the energy utilization rate of the energy storage system. Summary of the Invention

[0004] This invention provides a liquid cooling control method, device, equipment, and medium for container dual-loop units to solve the problems of slow response and low energy utilization.

[0005] In a first aspect, the present invention provides a liquid cooling control method for a containerized dual-loop unit, the dual-loop unit comprising: a battery circuit and an energy storage converter circuit, the method comprising:

[0006] Acquire historical operating data of the battery and energy storage converter, and predict the total heat generation increment for a future preset time period based on the historical operating data; Based on the current operating data of the energy storage converter, determine the operating mode of the dual-loop unit; The temperature control system is adjusted by acquiring the first temperature data of the battery circuit and the second temperature data of the energy storage converter circuit, and combining the total heat gain over a future preset time period and the operating mode of the dual-circuit unit.

[0007] The container dual-loop unit liquid cooling control method provided by this invention predicts the total heat increase by using historical data, adapts the operating mode by combining current PCS data, and then links the loop temperature dynamic adjustment temperature control system. This solves the lag of traditional liquid cooling post-event temperature control, pre-matches cooling resources, and ensures that the battery and PCS temperatures remain stable within a safe range. Through differentiated control of independent / linked dual loops, it avoids energy waste from long-term full-load operation of the equipment and significantly reduces the power consumption of the liquid cooling unit. At the same time, it adapts to multiple operating conditions such as low power and low temperature start-up, making the energy storage system safe and reliable in various scenarios and improving overall operating efficiency.

[0008] In one alternative implementation, historical operating data of the battery and energy storage converter are acquired, including: The data acquisition module collects the working data of the energy storage converter in real time through the data exchange and stores it as historical working data. The battery management unit collects the working data of at least one battery from the battery module in real time and stores it as historical working data for each battery. The battery module includes at least one battery.

[0009] The container dual-loop unit liquid cooling control method provided by this invention collects and stores the working data of the PCS and multiple batteries in real time through a data acquisition module, a data exchange, and a battery management unit, respectively, as historical data. This achieves accurate and comprehensive collection of PCS and battery data, avoiding the deviation in heat prediction caused by missing data from a single device. The modular independent collection and storage method ensures the real-time performance and accuracy of the data, and also facilitates subsequent individual analysis of the heat characteristics of different devices.

[0010] In one optional implementation, the battery's historical operating data includes: remaining capacity, charging / discharging power, operating current, and cell temperature; the energy storage converter's historical operating data includes: power module temperature and operating power; and the total heat generation increment over a preset future time period is predicted based on the historical operating data, including: Extract the battery's remaining capacity, charging and discharging power, operating current, and cell temperature change data for the corresponding time period from the battery's historical operating data to establish a battery heating model; The system obtains the battery's current remaining capacity, current charging / discharging power, and current operating current. Using the battery heating model and the battery's planned charging / discharging power curve for a future preset time period, it predicts the battery's heat generation increment for that time period. Based on the power module temperature prediction of the energy storage converter, the heat increment of the energy storage converter in the future preset time period is obtained by adding the heat increment of the battery and the heat increment of the energy storage converter to obtain the total heat increment.

[0011] The liquid cooling control method for containerized dual-loop units provided by this invention accurately predicts the total heat increment by selectively collecting core operating data of batteries and PCS and establishing a heat generation model. The heat generation prediction of batteries and PCS is more in line with actual operating conditions, avoiding prediction errors caused by generalized data. The heat generation increment is calculated in advance by combining the planned charge and discharge curves, realizing advance prediction rather than passive response, and reserving sufficient adjustment space for temperature control. The total increment is superimposed after the prediction of each equipment, taking into account the differences in heat generation characteristics of batteries and PCS, and accurately matching the cooling requirements of dual-loop units.

[0012] In one optional implementation, the operating mode of the dual-loop unit is determined based on the current operating data of the energy storage converter, including: The current operating power of the energy storage converter, the current power module temperature, the current remaining capacity of the battery, the current charging and discharging power, and the cell temperature are obtained. If the current operating power of the energy storage converter is less than the lower limit of the operating power, and the current power module temperature and cell temperature are both within the corresponding temperature range, then the dual-loop unit operates in low-power mode. If the dual-circuit unit operates within the preset time period after startup, and both the power module temperature and the cell temperature are within the low temperature threshold, then the dual-circuit unit operates in the low temperature startup mode. If the current operating power of the energy storage converter and the charging and discharging power of the battery both match the corresponding planned operating curves, then the operating mode of the dual-loop unit is the planned curve linkage operating mode.

[0013] The container dual-loop unit liquid cooling control method provided by this invention determines the operating mode by integrating multi-dimensional real-time data from the PCS and battery, making mode switching more in line with the actual operating conditions of the equipment and avoiding deviations in single parameter judgments. It accurately matches the corresponding mode for scenarios such as low power, low temperature start-up, and planned curves, ensuring the adaptability of temperature control adjustment under different operating conditions and avoiding energy waste or temperature control failure caused by incorrect mode switching.

[0014] In one optional implementation, the temperature control system includes: a first water pump, a first cooling device, a heating device, and a first three-way valve for the battery circuit; and a second water pump, a second cooling device, and a second three-way valve for the energy storage converter circuit. If the dual-loop unit operates in low-power mode, then the first temperature data of the battery circuit and the second temperature data of the energy storage converter circuit are acquired. Combined with the total heat gain over a preset time period and the operating mode of the dual-loop unit, the temperature control system is adjusted, including: Disconnect the first three-way valve and the second three-way valve to allow the battery circuit and the energy storage converter circuit to operate independently; Adjust the speed of the first water pump to a preset low speed range, and adjust the speed of the second water pump to a preset low speed range; Based on the difference between the first temperature data of the battery circuit and the first target temperature, the first cooling device is controlled to operate at the first minimum sustaining power. Based on the difference between the second temperature data of the energy storage converter circuit and the second target temperature, the second cooling device is controlled to operate at the second minimum sustaining power.

[0015] The liquid cooling control method for container dual-loop units provided by this invention enables independent operation of the two loops by disconnecting the three-way valve, avoiding heat interference between loops and adapting to the low-heat characteristics of the equipment under low-power conditions; by reducing the water pump speed and operating the cooling device with minimum sustaining power, the ineffective energy consumption of the liquid cooling system is significantly reduced while ensuring that the battery and PCS temperatures remain stable within the target range, meeting the energy-saving requirements of low-power conditions; and by precisely adjusting the cooling power based on the temperature difference, resource waste caused by overcooling is avoided, and the equipment temperature is stabilized.

[0016] In one optional implementation, if the dual-loop unit operates in a low-temperature start-up mode, then the first temperature data of the battery circuit and the second temperature data of the energy storage converter circuit are acquired, and the temperature control system is adjusted based on the total heat gain over a preset future time period and the operating mode of the dual-loop unit, including: If the power module temperature of the energy storage converter is greater than the cell temperature of the battery, then open the first three-way valve and the second three-way valve, adjust the speed of the first water pump to the preset medium speed range, and adjust the speed of the second water pump to the preset medium speed range. The heating device is shut down in advance based on the total heat generated over a future preset time period. The heating device is then shut down based on the advance shutdown time, while the first and second cooling devices remain off.

[0017] The liquid cooling control method for container dual-loop units provided by this invention, in low-temperature start-up operation mode, opens a three-way valve to connect the two loops, utilizes the higher temperature of the PCS power module to preheat the low-temperature battery, and achieves battery temperature rise without additional energy consumption, adapting to the heat utilization requirements of low-temperature start-up; the water pump is adjusted to the medium speed range to ensure the heat transfer efficiency between loops and avoid the energy waste of high speed; the heating device is shut down in advance in combination with the total heat generation, reducing the additional power consumption of the heating device, and at the same time shutting down the cooling device to prevent heat loss caused by accidental start-up of the cooling device.

[0018] In one optional implementation, if the dual-loop unit operates in a planned curve-linked operation mode, then the first temperature data of the battery circuit and the second temperature data of the energy storage converter circuit are acquired, and the temperature control system is adjusted in conjunction with the total heat increment over a future preset time period and the operating mode of the dual-loop unit, including: Based on the first temperature data and the planned operation curve of charging and discharging power, the battery heat generation increment is predicted for a future preset time period. Based on the second temperature data and the calculated operation curve of operating power, the energy storage converter heat generation increment is predicted for a future preset time period. The power of the first cooling device and the speed of the first water pump are adjusted in real time according to the battery heat generation increment over a future preset time period. The power of the second cooling device and the speed of the second water pump are also adjusted in real time according to the energy storage converter heat generation increment over a future preset time period.

[0019] The container dual-loop unit liquid cooling control method provided by this invention predicts the heat generation increment of the battery and PCS respectively by combining the planned operation curve, so that the temperature control adjustment is precisely matched with the expected operating conditions of the equipment. The power of the cooling device and the speed of the water pump are adjusted in real time according to the heat generation increment of the two, realizing differentiated and precise temperature control of the dual loop. This can stabilize the battery and PCS within the target temperature range without wasting cooling resources.

[0020] Secondly, the present invention provides a liquid-cooled control device for a container dual-loop unit, the dual-loop unit comprising: a battery circuit and an energy storage converter circuit, the device comprising: The heat generation prediction module is used to acquire historical operating data of the battery and energy storage converter, and predict the total heat generation increment for a future preset time period based on the historical operating data. The operation mode determination module is used to determine the operation mode of the dual-loop unit based on the current operating data of the energy storage converter; The temperature control module is used to acquire the first temperature data of the battery circuit and the second temperature data of the energy storage converter circuit, and adjust the temperature control system in combination with the total heat increase over a future preset time period and the operating mode of the dual-circuit unit.

[0021] Thirdly, the present invention provides an electronic device, comprising: a memory and a processor, the memory and the processor being communicatively connected to each other, the memory storing computer instructions, and the processor executing the computer instructions to perform the method described in the first aspect or any corresponding embodiment thereof.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] As an optional application scenario of this invention, such as Figure 1 As shown, the structure of the dual-loop liquid-cooled temperature control system for the energy storage container is as follows: The TMS system is the liquid-cooled temperature control device serving the energy storage container, including dual-loop units that respectively liquid-cool the battery and the power conversion system (PCS). The battery loop consists of a first water pump, a first cooling device, a first three-way valve, and a heating device; the power conversion system loop consists of a second water pump, a second cooling device, and a second three-way valve. The two loops can operate independently or in conjunction. The water pump is responsible for driving the coolant circulation, the cooling device is used to cool the coolant, the heating device is used to supplement the heat of the loop under low-temperature conditions, and the three-way valve is used to control the on / off state of the two loops.

[0030] This invention provides a liquid cooling control method for a container dual-loop unit. By collecting the operating data of the dual-loop unit, the method predicts the heat generation increment within a preset time period and takes temperature control strategies in advance to achieve timely response to temperature changes and improve energy utilization.

[0031] According to an embodiment of the present invention, a liquid cooling control method for a container dual-loop unit is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0032] This embodiment provides a liquid cooling control method for a containerized dual-loop unit, which can be used in the aforementioned computer system. Figure 2 This is a flowchart of a container dual-loop unit liquid cooling control method according to an embodiment of the present invention, such as... Figure 2 As shown, the process includes the following steps: Step S201: Obtain historical operating data of the battery and energy storage converter, and predict the total heat generation increment for a future preset time period based on the historical operating data.

[0033] Specifically, the battery's operating data includes remaining charge, cell temperature, internal resistance, and current. The current is directly related to the battery's charging and discharging power. The higher the charging and discharging power, the stronger the heat generation. Combined with the cell temperature, the battery temperature rise over a preset period of time can be predicted. For example, a large remaining charge and a large current will cause the battery to heat up rapidly, providing a basis for adjusting the temperature control system in advance.

[0034] The temperature of the power module in the PCS directly reflects the heat dissipation pressure of the PCS. The higher the temperature of the power module, the stronger the cooling effect on the PCS.

[0035] By utilizing historical operating data of the battery, the relationship between cell temperature and other operating data under different operating conditions is found, forming a battery heating curve. Then, the changing trend of the cell temperature is predicted by using the changing trend of the other operating data. Similarly, by utilizing historical operating data of the energy storage converter, the relationship between power module temperature and other operating data under different operating conditions is found, forming a PCS heating curve. Then, the changing trend of the other operating data is predicted by using the changing trend of the energy storage converter. By combining the cell temperature and the temperature of the energy storage converter, the total heat increment for a future preset time period (e.g., 5-10 minutes) can be determined.

[0036] Step S202: Determine the operating mode of the dual-loop unit based on the current operating data of the energy storage converter.

[0037] Specifically, the operating status of the PCS (low power / rated power) determines the dual-loop operating mode (independent / interlocked). For example, at low power, the PCS generates less heat and does not need to be connected to the battery circuit, avoiding unnecessary energy consumption. This is just an example and is not a limitation. The power change of the PCS directly corresponds to the total heat generation. Therefore, the operating data of the PCS is used as the basis for determining the dual-loop operating mode, so that the temperature control strategy can accurately match the actual heat demand and avoid the problem of overcapacity or undercapacity.

[0038] Step S203: Obtain the first temperature data of the battery circuit and the second temperature data of the energy storage converter circuit, and adjust the temperature control system in combination with the total heat increase over a future preset time period and the operating mode of the dual-circuit unit.

[0039] Specifically, in a dual-loop unit, the inlet and outlet water temperatures of each loop directly reflect the cooling effect. For example, if the battery water temperature is higher than 22°C, it indicates insufficient cooling of the battery. In this case, increasing the pump speed in the battery loop or increasing the power of the cooling device can be used as an example, but it is not a limitation. The cooling devices in each loop primarily use compressors for cooling. The cooling system load can be determined by combining the power of the cooling devices and the water flow rate in each loop to avoid overcooling.

[0040] The first temperature data of the battery circuit and the second temperature data of the energy storage converter circuit represent the current temperature of the cooling medium (usually water). The total heat increment over a future preset time period is the object that the temperature control system needs to adjust. The operating mode of the dual-loop unit determines whether to adjust the single-loop or the linkage adjustment, which affects the adjustment of the temperature control equipment of each circuit. Therefore, it is necessary to adjust the temperature control system in combination with the total heat increment over a future preset time period and the operating mode of the dual-loop unit to ensure that the temperature control system meets the cooling requirements of the battery and PCS, while reducing energy waste when the temperature is low.

[0041] The container dual-loop unit liquid cooling control method provided in this embodiment predicts the total heat increase by using historical data, adapts the operating mode by combining current PCS data, and then links the loop temperature dynamic adjustment temperature control system. This solves the lag of traditional liquid cooling's post-event temperature control, pre-matches cooling resources, and ensures that the battery and PCS temperatures remain stable within a safe range. Through differentiated control of independent / linked dual loops, it avoids energy waste from long-term full-load operation of the equipment and significantly reduces the power consumption of the liquid cooling unit. At the same time, it adapts to multiple operating conditions such as low power and low temperature start-up, making the energy storage system safe and reliable in various scenarios while improving overall operating efficiency.

[0042] This embodiment provides a liquid cooling control method for a containerized dual-loop unit, which can be used in the aforementioned computer system. Figure 3 This is a flowchart of a container dual-loop unit liquid cooling control method according to an embodiment of the present invention, such as... Figure 3 As shown, the process includes the following steps: Step S301: Obtain historical operating data of the battery and energy storage converter, and predict the total heat generation increment for a future preset time period based on the historical operating data.

[0043] Specifically, step S301 includes: Step S3011: The data acquisition module collects the working data of the energy storage converter in real time from the energy storage converter through the data exchange and stores it as historical working data.

[0044] Specifically, such as Figure 4 The diagram shown is a communication schematic for data acquisition. BAU is the highest control unit (Battary Aggregation Unit) of the battery management system, also known as the master controller, which is used to receive and store the working data of the TMS, battery, and energy storage converter.

[0045] The operating data of the energy storage converter is transmitted through the local area network (LAN). It first passes through the data switch, then reaches the data acquisition module, and finally is transmitted to the BAU. The BAU stores the operating data of the energy storage converter in real time according to the receiving time, forming historical operating data.

[0046] Step S3012: The battery management unit collects the working data of at least one battery from the battery module in real time and stores it as the historical working data of each battery. The battery module includes at least one battery.

[0047] Specifically, such as Figure 4As shown, a battery module (Rack) is a carrier for installing batteries. A Rack includes at least one battery pack, which is a battery unit composed of multiple battery cells. The Rack acts as a carrier, uploading the operating data of at least one battery pack to the corresponding Battery Management Unit (BMU). The BMU then forwards the data to the BAU, which stores the battery's operating data according to the time of receipt, forming the battery's historical operating data.

[0048] In addition to the battery's operating data and the energy storage converter's operating data, the BAU is also connected to the TMS to obtain the TMS's operating data (including but not limited to: real-time current, battery temperature, SOC, power module temperature, liquid chiller water temperature, compressor power, branch flow, etc.). At the same time, it adjusts parameters such as the power of the cooling device and heating device in the TMS, the on / off state of the three-way valve, and the water pump speed (which directly affects the flow rate).

[0049] The container dual-loop unit liquid cooling control method provided in this embodiment collects and stores the working data of the PCS and multiple batteries in real time through a data acquisition module, a data exchange, and a battery management unit, respectively, as historical data. This achieves accurate and comprehensive collection of PCS and battery data, avoiding the deviation in heat prediction caused by missing data from a single device. The modular independent collection and storage method ensures the real-time performance and accuracy of the data, and also facilitates subsequent individual analysis of the heat characteristics of different devices.

[0050] In some optional implementations, the battery's historical operating data includes: remaining capacity, charge / discharge power, operating current, and cell temperature; the energy storage converter's historical operating data includes: power module temperature and operating power; and step S301 further includes: Step S3013: Extract the battery's remaining charge, charging and discharging power, operating current, and cell temperature change data for the corresponding time period from the battery's historical operating data to establish a battery heating model.

[0051] Specifically, key parameters such as remaining charge (SOC), charge / discharge power, operating current, and cell temperature are extracted from the battery's historical operating data. The changes in cell temperature are then identified, for example, the change in cell temperature over time at a fixed SOC and charge / discharge power. This data on remaining charge, charge / discharge power, operating current, and cell temperature changes over the corresponding time periods is compiled into a data model, which serves as a reference standard for subsequent predictions of battery heat generation. For example, when the SOC is 80% and the charge / discharge power is 50kW, the cell temperature rises by 2°C every 5 minutes; this is just an example and not a limitation.

[0052] Step S3014: Obtain the current remaining battery capacity, current charge / discharge power, and current operating current. Using the battery heating model and the planned charge / discharge power curve of the battery over a future preset time period, predict the battery heating increment over the future preset time period.

[0053] Specifically, the system obtains the battery's current remaining charge, current charging / discharging power, and current operating current. Combined with a pre-defined planned charging / discharging power curve for a future time period (e.g., discharging at 60kW for the next 10 minutes), the system uses a battery heating model to calculate the battery's temperature change over the future time period, i.e., the battery's heat generation increment.

[0054] Step S3015: Based on the power module temperature prediction of the energy storage converter, predict the heat generation increment of the energy storage converter in the future preset time period, add the heat generation increment of the battery to the heat generation increment of the energy storage converter to obtain the total heat generation increment.

[0055] Specifically, based on the current power module temperature of the PCS and its heat generation pattern (e.g., how much heat generation increment corresponds to each 1°C increase in power module temperature), the heat generation increment of the PCS over a future preset time period is calculated. Then, the heat generation increment of the battery is added to the heat generation increment of the PCS to obtain the total heat generation increment of the entire energy storage system over the future preset time period.

[0056] The container dual-loop unit liquid cooling control method provided in this embodiment accurately predicts the total heat increment by selectively collecting core operating data of the battery and PCS and establishing a heat generation model. The heat generation prediction of the battery and PCS is more in line with the actual operating conditions, avoiding prediction errors caused by generalized data. The heat generation increment is calculated in advance by combining the planned charge and discharge curves, realizing advance prediction rather than passive response, and reserving sufficient adjustment space for temperature control. The total increment is superimposed after the prediction of each equipment, taking into account the differences in heat generation characteristics of the battery and PCS, and accurately matching the cooling requirements of the dual-loop unit.

[0057] Step S302: Determine the operating mode of the dual-loop unit based on the current operating data of the energy storage converter.

[0058] Specifically, step S302 includes: Step S3021: Obtain the current operating power of the energy storage converter, the current power module temperature, the current remaining battery capacity, the current charging and discharging power, and the cell temperature. If the current operating power of the energy storage converter is less than the lower limit of the operating power, and the current power module temperature and cell temperature are both within the corresponding temperature range, then the dual-loop unit operates in low-power mode.

[0059] Specifically, when the PCS operates at low power (30% of its rated power) (e.g., during grid off-peak periods when the energy storage system only provides low-power supplementary power), the PCS's own power modules generate very little heat, and the battery is also in a low charge / discharge state with minimal heat increase. Forcing a connection between the two circuits at this time would actually increase water pump energy consumption due to coolant circulating in both circuits, and could also cause interference between the already low-heat circuits (e.g., the battery's low temperature being conducted to the PCS). Therefore, determining an independent operating mode based on the PCS's low-power state satisfies the temperature control requirements under low heat generation while avoiding unnecessary energy consumption.

[0060] Step S3022: If the dual-circuit unit operates within the preset time period after startup and both the power module temperature and the cell temperature are within the low temperature threshold, then the dual-circuit unit operates in the low temperature startup mode.

[0061] Specifically, during the PCS startup phase (e.g., when the energy storage system is first started), the PCS power module will heat up rapidly (but the overall power is not yet stable), while the battery may be in a low-temperature state. At this time, based on the PCS startup and the low-temperature state, a low-temperature startup mode is determined. Connecting the dual circuits can utilize the initial heat of the PCS to preheat the battery, which saves the energy consumption of additional heating devices and allows the battery to quickly reach the appropriate operating temperature.

[0062] Step S3023: If the current operating power of the energy storage converter and the charging and discharging power of the battery both match the corresponding planned operating curves, then the operating mode of the dual-loop unit is the planned curve linkage operating mode.

[0063] Specifically, during normal operation of the energy storage system, such as during peak grid periods, the system discharges at high power, causing the PCS power modules to generate concentrated and substantial heat (the heat load is several times that at low power). Meanwhile, the battery is also in a high charge / discharge state, experiencing a surge in heat generation. Both the PCS and the battery operate according to their respective planned operating curves (neither at minimum power). If the dual circuits remain independent, insufficient cooling capacity in the PCS circuit and uncontrolled temperature in the battery circuit may occur. Therefore, the linkage operation mode is determined by the PCS's rated power state. Connecting the dual circuits allows for coordinated allocation of cooling resources, preventing localized overheating.

[0064] The container dual-loop unit liquid cooling control method provided in this embodiment determines the operating mode by integrating multi-dimensional real-time data from the PCS and battery, making mode switching more in line with the actual operating conditions of the equipment and avoiding deviations in single parameter determination; it accurately matches the corresponding mode for scenarios such as low power, low temperature start-up, and planned curves, ensuring the adaptability of temperature control adjustment under different operating conditions and avoiding energy waste or temperature control failure caused by incorrect mode switching.

[0065] Step S303: Obtain the first temperature data of the battery circuit and the second temperature data of the energy storage converter circuit, and adjust the temperature control system in combination with the total heat increase over a future preset time period and the operating mode of the dual-circuit unit.

[0066] Specifically, the temperature control system includes: a first water pump, a first cooling device, a heating device, and a first three-way valve for the battery circuit; and a second water pump, a second cooling device, and a second three-way valve for the energy storage converter circuit. If the operating mode of the dual-loop unit is low-power operation mode, then step S303 above includes: Step S303a1: Disconnect the first three-way valve and the second three-way valve to allow the battery circuit and the energy storage converter circuit to operate independently.

[0067] Specifically, during normal operation, the water temperature entering the PCS is stable at 35~40℃, and the water temperature entering the battery is stable at 20±2℃.

[0068] At room temperature and during low-power operation, both the battery and the PCS generate relatively little heat and do not need to share cooling resources. Therefore, if Figure 5 As shown, disconnect the first three-way valve and the second three-way valve to allow the battery circuit and the energy storage converter circuit to operate independently. This prevents the coolant from idling in low-heat scenarios after the circuits are connected, and also prevents the temperatures of the two circuits from interfering with each other, such as the low temperature of the battery affecting the temperature stability of the PCS.

[0069] Step S303a2: Adjust the speed of the first water pump to a preset low speed range, and adjust the speed of the second water pump to a preset low speed range.

[0070] Specifically, the water pump is the power source that drives the circulation of coolant, and the higher the speed, the greater the energy consumption. In low-power mode, less heat is generated, and the coolant does not need to circulate at high speed to meet the heat dissipation requirements. Therefore, the speeds of the first water pump (battery circuit) and the second water pump (PCS circuit) are both adjusted to a preset low-speed range (e.g., 20%-30% of the rated speed). This ensures that the coolant can flow normally to remove a small amount of heat, while also significantly reducing the operating energy consumption of the water pumps.

[0071] In step S303a3, based on the difference between the first temperature data of the battery circuit and the first target temperature, the first cooling device is controlled to operate at the first minimum sustaining power, and based on the difference between the second temperature data of the energy storage converter circuit and the second target temperature, the second cooling device is controlled to operate at the second minimum sustaining power.

[0072] Specifically, the power of the cooling device needs to match the actual heat dissipation requirements. First, compare the difference between the current temperature (first temperature data) and the target temperature (first target temperature) of the battery circuit, and then compare the difference between the current temperature (second temperature data) and the target temperature (second target temperature) of the PCS circuit. Based on these two differences, both the first and second cooling devices should operate at the minimum power that can just maintain temperature stability (e.g., 10%-20% of the rated power). The first and second cooling devices should operate independently at low power thresholds, so that overcooling (wasting energy) will not occur due to excessive power, and temperature runaway will not occur due to insufficient power.

[0073] The container dual-loop unit liquid cooling control method provided in this embodiment achieves independent operation of the two loops by disconnecting the three-way valve, avoiding heat interference between loops and adapting to the low-heat characteristics of the equipment under low-power conditions; it reduces the water pump speed and operates the cooling device with minimum maintenance power, significantly reducing the ineffective energy consumption of the liquid cooling system while ensuring that the battery and PCS temperatures remain stable within the target range, meeting the energy-saving requirements of low-power conditions; and it precisely adjusts the cooling power based on the temperature difference, avoiding resource waste caused by overcooling and stabilizing the equipment temperature.

[0074] In some optional implementations, if the operating mode of the dual-loop unit is: low-temperature start-up operating mode, then step S303 above includes: In step S303b1, if the power module temperature of the energy storage converter is greater than the cell temperature of the battery, the first three-way valve and the second three-way valve are opened, the speed of the first water pump is adjusted to the preset medium speed range, and the speed of the second water pump is adjusted to the preset medium speed range.

[0075] Specifically, during low-temperature startup, for example, when the ambient temperature is not lower than -5℃ (to avoid the risk of freezing at extreme low temperatures), the current power of the PCS is ≥20% of the rated power (to ensure sufficient heat generation from the PCS), the current battery temperature is ≥10℃ (it has escaped the freezing point and can be warmed up by residual heat), and the battery temperature is estimated to be ≥15℃ within 10 minutes (predicted by a power-temperature rise algorithm to ensure that the temperature continues to rise after the heating is turned off), then the first three-way valve and the second three-way valve are opened to connect the battery circuit and the PCS circuit. Then, the water pump speeds of the two circuits are adjusted to a preset medium speed range (e.g., 50%-60% of the rated speed). Connecting the two circuits allows the heat from the PCS to be transferred to the low-temperature battery through the coolant, achieving preheating with heat. The medium-speed water pump ensures the circulation efficiency of the coolant, allowing heat to be transferred more smoothly from the PCS to the battery, while avoiding the additional energy consumption caused by high speed.

[0076] Step S303b2: Determine the early shutdown time of the heating device based on the total heat generation over a future preset time period, and control the heating device to shut down based on the early shutdown time, while keeping the first cooling device and the second cooling device off.

[0077] Specifically, based on the total heat generated over a preset time period (the sum of heat generated by the PCS and the battery), the pre-shutdown time of the heating device is calculated (e.g., the time when the total heat generated is sufficient to raise the battery to the target temperature). At this time, the heating device is turned off, while the first and second cooling devices remain off. The heat generated by the PCS during startup is used to preheat the battery, saving the extra power consumption of the heating device and preventing the cooling device from accidentally starting and offsetting the heat, making the low-temperature startup process more energy-efficient and effective.

[0078] The liquid cooling control method for the container dual-loop unit provided in this embodiment, in the low-temperature start-up operation mode, opens the three-way valve to connect the two loops, and uses the higher temperature of the PCS power module to preheat the low-temperature battery, achieving battery temperature rise without additional energy consumption, which is suitable for the heat utilization requirements of low-temperature start-up; the water pump is adjusted to the medium speed range to ensure the heat transfer efficiency between the loops and avoid the energy waste of high speed; the heating device is shut down in advance in combination with the total heat generation, reducing the additional power consumption of the heating device, and at the same time shutting down the cooling device to prevent heat loss caused by accidental start of the cooling device.

[0079] In some optional implementations, if the operating mode of the dual-loop unit is: planned curve linkage operation mode, then step S303 above includes: Step S303c1: Based on the first temperature data and the planned operation curve of charging and discharging power, predict the battery heat generation increment for a future preset time period; based on the second temperature data and the calculated operation curve of operating power, predict the energy storage converter heat generation increment for a future preset time period.

[0080] Specifically, in the planned curve linkage mode, the energy storage system operates according to a preset operating plan (such as the charging and discharging curve of the power grid dispatch). At this time, for the battery, the heat generation of the battery will increase in the future preset time period is calculated by combining the first temperature data of the current battery circuit and the planned charging and discharging power curve of the battery. That is, the battery heat generation increment.

[0081] For the PCS, by combining the current second temperature data of the PCS circuit and the planned operating power curve of the PCS in the future, the heat generation of the PCS will increase in the future within a preset time period, that is, the heat generation increment of the PCS.

[0082] Step S303c2: Adjust the power of the first cooling device and the speed of the first water pump in real time according to the battery heat generation increment over a future preset time period; adjust the power of the second cooling device and the speed of the second water pump in real time according to the energy storage converter heat generation increment over a future preset time period.

[0083] Specifically, for the battery circuit, the power of the first cooling device and the speed of the first water pump are adjusted in advance according to the amount of battery heat increase (increase the power if more heat is generated) and the speed of the first water pump (increase the speed to speed up the circulation of coolant if more heat is generated).

[0084] For the PCS circuit, the power of the second cooling device and the speed of the second water pump are adjusted in advance according to the amount of heat increase in the PCS. By precisely matching the heat increase with the temperature control parameters, the temperature of the battery and PCS can be stabilized within the target range without wasting cooling resources, thus meeting the high-efficiency requirements of the planned operation mode.

[0085] The container dual-loop unit liquid cooling control method provided in this embodiment predicts the heat generation increment of the battery and PCS respectively by combining the planned operation curve, so that the temperature control adjustment is precisely matched with the expected operating conditions of the equipment. The power of the cooling device and the speed of the water pump are adjusted in real time according to the heat generation increment of the two, realizing differentiated and precise temperature control of the dual loop. This can stabilize the battery and PCS within the target temperature range without wasting cooling resources.
