Description

Technical Field

[0001] The present invention relates to the field of liquid cooling performance testing, and in particular to a testing platform and method for an embedded energy storage liquid cooling system production line. Background Art

[0002] The performance test of the energy storage liquid cooling system production line is crucial to ensure that the liquid cooling system meets the product design requirements and relevant standards. It is directly related to the stability of the product and the high requirements of energy storage applications. In the energy storage system, the battery pack will generate a lot of heat during the charging and discharging process. If it cannot be dissipated in time, the temperature of the battery pack will continue to rise, which will not only lead to a decrease in battery performance and shortened life, but may also cause serious safety accidents such as thermal runaway. The liquid cooling system can quickly and effectively remove the heat generated by the battery pack through the circulation of coolant to ensure that the battery pack operates within a safe and stable temperature range. In addition, the performance and life of the energy storage battery pack will also be significantly affected in a low temperature environment, mainly manifested as: the battery capacity and charging and discharging efficiency decrease, the battery cell accelerates aging, and the battery life is sharply shortened. The liquid cooling system can preheat the battery pack by circulating a liquid with a certain temperature in the heat exchange plate channel placed at the bottom of the battery pack, thereby increasing the operating temperature and working performance of the battery pack. Therefore, the cooling / heating capacity of the liquid cooling system has become one of the key performances of the energy storage system, and the corresponding cooling / heating performance test is also extremely important in the production process of the energy storage liquid cooling system.

[0003] At present, no company has adopted an embedded fully automatic refrigeration / heating performance test platform in the energy storage liquid cooling system production line. Most manufacturers are still using semi-automatic performance test platforms for testing. These devices take up a lot of production space, and the testing process is not intelligent enough. Specifically, the semi-automatic platform cannot automatically fill and discharge the test liquid, nor can it automatically calculate the cooling / heating capacity, which causes the testing process to consume a lot of manpower and the analysis process is time-consuming. This platform is usually placed in the environment around the production line, and the large liquid storage tank is placed on the ground around the production line, thus occupying additional production space and causing inconvenience to the production line workers.

[0004] In addition, the existing external semi-automatic energy storage liquid cooling system cooling / heating performance test platform requires manual operation of various water and gas valves during the entire test process, and manual control of the start and stop of each step, which consumes a lot of manpower and time;

[0005] At the same time, most of the existing external semi-automatic energy storage liquid cooling system refrigeration / heating performance test platforms adopt the idea of ​​filling the test unit with air to discharge the residual test liquid in the unit. However, due to the certain height difference between the liquid circuit, gas circuit of the test platform and the circulating liquid circuit in the test unit, and the density difference between the air and the test liquid, it is difficult to completely discharge the residual test liquid in the test unit, resulting in corrosion of the key components of the test unit (water pump, condenser, etc.) and the inner wall of the connecting pipe, which will affect the subsequent normal use of the test unit to a certain extent.

[0006] Therefore, we proposed a testing platform and method for the production line of embedded energy storage liquid cooling system to solve the above problems. Summary of the invention

According to the cooling / heating power, it is determined whether the preset performance requirements are met. If the preset performance requirements are not met, cooling or heating is continued; if they are met, cooling or heating is stopped. A performance test report is generated, which at least includes the working environment temperature, the working test liquid temperature, and the total time to meet the preset performance requirements.

[0031] Optionally, in a fifth implementation of the first aspect of the present invention, the drainage function adopts a two-stage drainage design, including a high-level main drainage stage and a low-level auxiliary drainage stage, to ensure that the residual test liquid in the pipeline is completely discharged; by adding a liquid cooling unit filling port located at a lower vertical position as an auxiliary drainage port, a small amount of residual test liquid remaining in the liquid cooling unit components is discharged from the low-level unit filling port to an open liquid storage tank 2 with a lid embedded in the lower part of the assembly line table.

[0032] The second aspect of the present invention provides a test platform for an embedded energy storage liquid cooling system production line, wherein the test platform for the embedded energy storage liquid cooling system production line includes: a power module, used to provide power to the test platform and the test liquid cooling unit; a test platform host computer, used to control the circuit, water and gas communication between the test platform and the test liquid cooling unit, and is responsible for the test work; a data acquisition module, including a temperature sensor and a flow sensor, used to measure the temperature and flow data during the test process; a test platform main line, including a water pipeline and a gas pipeline, used to connect the test platform and the test liquid cooling unit; a liquid storage tank module, including at least one liquid storage tank, used to store and supply test liquid.

[0036] The technical solution provided by the present invention has the following beneficial effects:

[0037] The test platform is completely embedded in the production line and does not occupy additional space in the production workshop. This design not only reduces the floor space of the production line, but also allows workers on the production line to have more working space, improving space utilization efficiency. The embedded design of the liquid storage tank and pipeline (located on the top of the production line and under the table) further enhances the synergy of space utilization, achieves "zero occupancy" of the production space, and makes the production line layout more compact and efficient.

[0038] The present invention realizes automated testing. Production line workers only need to control the control panel on the test platform to complete the test, greatly reducing the manpower requirements. Intelligent control further improves the test efficiency. The platform can automatically collect and process data, automatically determine the type of test performance, and automatically calculate the cooling / heating capacity, achieving "zero consumption" of the labor of production line workers during the performance test. The synergy of automation and intelligence makes the test process smoother and more efficient, significantly improving production efficiency.

[0039] A reasonable layout of gas and liquid circuits is adopted, and the "two-stage drainage" design of high-level main drainage and low-level auxiliary drainage is used to achieve complete drainage of residual test liquid. The synergy of this gas and liquid circuit design not only solves the problem of incomplete drainage, but also avoids corrosion of key components of the test unit and the inner wall of the connecting pipeline, extending the service life of the test unit.

[0040] The overall structural design (including power supply, test platform host computer, data acquisition module, test platform main line, liquid storage tank, etc.) and various functions (such as filling and replenishing, collecting ambient temperature data, liquid cooling unit drainage, etc.) form a good synergy. This synergy enables the test platform to stably and reliably complete performance test tasks, while ensuring the accuracy and reliability of test results.

[0041] To sum up, the fully automatic refrigeration / heating performance intelligent testing platform for the embedded energy storage liquid cooling system production line created by the present invention realizes full utilization of production space, automation and intelligence of the testing process, complete drainage of residual test liquid and stability and reliability of the overall structure through the synergy of space utilization, automation and intelligence, gas and liquid circuit design, and overall structure and function, thereby significantly improving production efficiency, reducing labor costs, extending the service life of the test unit, and ensuring the accuracy and reliability of the test results.

[0047] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of a performance testing method for an embedded energy storage liquid cooling system production line in an embodiment of the present invention includes:

[0048] 101. The test platform is fully embedded in the production line, and the circuit communication, water communication and gas communication between the test platform and the energy storage liquid cooling system to be tested are controlled by the host computer of the test platform;

[0049] It is understandable that the execution subject of the present invention may be a test platform of an embedded energy storage liquid cooling system production line, or a terminal or a server, which is not specifically limited here. The embodiment of the present invention is described by taking a server as the execution subject as an example.

[0050] It should be noted that the hardware equipment of the test platform (including sensors, controllers, actuators, etc.) is tightly integrated into the production line to ensure physical connection with the energy storage liquid cooling system to be tested. Standardized interfaces and connectors are used to quickly and accurately connect and disconnect the test platform and the system to be tested.

[0051] Circuit communication interface design: Design a dedicated circuit interface to ensure that the electrical connection between the test platform and the energy storage liquid cooling system to be tested is stable and reliable. Use standardized communication protocols such as CAN bus or Modbus (485 communication protocol, baud rate of 115200) to achieve accurate data transmission.

[0052] Data transmission and monitoring: The upper computer software monitors the circuit communication status in real time, including key parameters such as voltage and current. For example, it can be set to collect circuit data every 50ms to ensure real-time grasp of the system status.

[0053] Specific data: In one test, the test platform successfully obtained the real-time voltage data of the energy storage liquid cooling system to be tested, which was 220V, and the current data was 10A through circuit communication, ensuring that the system operated within the normal range.

[0054] Waterway communication is realized, fluid connection: Use special water pipes and joints to connect the test platform with the waterway of the energy storage liquid cooling system to be tested. Ensure the sealing and smoothness of the waterway connection to prevent liquid leakage or blockage.

[0055] Flow and temperature monitoring: Flow sensors and temperature sensors are installed in the water circuit to monitor the flow and temperature of the coolant in real time. The host computer software displays and records these data in real time to analyze system performance.

[0056] Specific data: In a certain test, the water channel communication successfully monitored the coolant flow rate of 5L / min and the temperature of 25°C, indicating that the liquid cooling system was working normally.

[0057] Gas communication is realized, gas connection: Use special gas pipes and joints to connect the test platform with the gas path of the energy storage liquid cooling system to be tested. Ensure the sealing and patency of the gas path connection to prevent gas leakage or blockage.

[0058] Pressure and humidity monitoring: Install pressure sensors and humidity sensors in the gas circuit to monitor the pressure and humidity of the system in real time. The host computer software monitors and records these data in real time to detect abnormal conditions in time.

[0059] Specific data: In a gas circuit communication test, the system pressure was successfully monitored to be 1.5 bar and the humidity was 40%, which met the design requirements.

[0060] Host computer control, software development: Develop dedicated host computer software to control the communication between the test platform and the energy storage liquid cooling system to be tested. The host computer software has data acquisition, analysis, storage and alarm functions.

[0061] Real-time control: The operation of the test platform is controlled in real time through the host computer software, including start, stop, data acquisition and other operations. The host computer software can display various data in real time and provide abnormal alarm function.

[0062] In summary, by fully embedding the test platform into the production line and controlling the circuit communication, water communication and gas communication between the test platform and the energy storage liquid cooling system to be tested based on the host computer of the test platform, comprehensive testing and monitoring of the performance of the energy storage liquid cooling system can be achieved.

[0063] 102. Fill the energy storage liquid cooling system to be tested with a test liquid, obtain the ambient temperature (including the device temperature) and flow data during the test in response to the filling, and start the cooling or heating function of the energy storage liquid cooling system to be tested according to the ambient temperature and flow data;

[0064] It should be noted that the test liquid is prepared: select an appropriate test liquid, such as an ethylene glycol aqueous solution, and ensure that its heat capacity and fluidity meet the test requirements. Connect the pipeline: Use special pipelines and connectors to connect the test liquid filling equipment to the liquid cooling pipeline of the energy storage liquid cooling system to be tested. Filling process: Start the filling equipment and slowly fill the test liquid into the energy storage liquid cooling system to be tested, while monitoring the pressure changes of the system to ensure that the filling process is safe and correct. Confirm the filling amount: After the filling is completed, check whether the amount of test liquid in the energy storage liquid cooling system to be tested reaches the preset value. For example, fill to 80% of the system capacity.

[0065] Acquire ambient temperature and flow data. Ambient temperature monitoring: Arrange temperature sensors in the test environment to monitor and record ambient temperature data in real time. For example, the initial temperature of the test environment is 25°C. Flow data acquisition: Install flow sensors in the liquid cooling pipeline to monitor and record the flow data of the test liquid in real time. For example, the initial flow rate is set to 3L / min.

[0066] Turn on the cooling or heating function based on the data. Data analysis: Input the real-time monitored ambient temperature and flow data into the host computer control system for analysis. Function judgment: According to the analysis results, judge whether it is necessary to turn on the cooling or heating function of the energy storage liquid cooling system to be tested. For example, when the ambient temperature (including the equipment temperature) exceeds 30°C, turn on the cooling function; when the ambient temperature (including the equipment temperature) is lower than 20°C, turn on the heating function. Function execution: According to the judgment result, send instructions to the energy storage liquid cooling system to be tested through the host computer control system to turn on the corresponding cooling or heating function. For example, when the current ambient temperature is 28°C, the system determines that there is no need to turn on the cooling or heating function and maintains the current state.

[0067] Monitoring and recording of the test process, real-time monitoring: During the test process, the ambient temperature, flow rate and the operating status of the energy storage liquid cooling system to be tested are continuously monitored. Data recording: The real-time monitored data is recorded in the host control system for subsequent analysis and processing. For example, the changes in ambient temperature and flow rate data are recorded every 5 minutes. Abnormal handling: If an abnormal situation is found (such as a sudden decrease in flow rate, a sudden increase in ambient temperature, etc.), stop the test immediately and check the cause to ensure the safety and effectiveness of the test process.

[0068] Through the above embodiments, the operations of filling the test liquid, obtaining the ambient temperature and flow data, and starting the cooling or heating function according to these data in the performance test of the embedded energy storage liquid cooling system production line can be specifically implemented.

[0069] 103. Collect temperature and flow data of the energy storage liquid cooling system to be tested during the cooling or heating process, and calculate the cooling / heating power, and determine whether the preset performance requirements are met according to the cooling / heating power. If the preset performance requirements are not met, continue cooling or heating, and if they are met, stop cooling or heating;

[0070] It should be noted that the sensors are arranged: temperature sensors and flow sensors are installed at key parts of the energy storage liquid cooling system to be tested (such as inlet and outlet, radiator, etc.) to ensure that the temperature and flow data during the cooling or heating process can be accurately collected. Data collection: After starting the cooling or heating function, the temperature and flow data are collected in real time through sensors. For example, data is collected every 10 seconds to ensure the continuity and accuracy of the data.

[0071] Specific data example:

[0072] Initial temperature: 25℃

[0073] Target cooling temperature: 15°C

[0074] Initial flow rate: 4L / min

[0075] During the cooling process, the temperature and flow data recorded every 10 seconds are as follows:

[0076] t=10s: temperature=23℃, flow rate=4.1L / min

[0077] t=20s: temperature=21℃, flow rate=4.0L / min

[0078] ...(and so on)

[0079] Calculate the cooling / heating power. The power calculation formula is: According to the characteristics of the liquid cooling energy storage system, the cooling / heating power (P) can be calculated by the system input power (P in ) and output power (P out ) and energy conversion efficiency (η). In practical applications, the cooling / heating power can be estimated by using temperature and flow data in a simplified manner. Data processing: The collected temperature and flow data are input into the power calculation model to obtain the real-time cooling / heating power.

[0080] Specific data example:

[0081] When t=60s is set, the collected temperature is 17℃ and the flow rate is 3.9L / min. The calculation model shows that the cooling power at this time is P=1.5kW.

[0082] Determine whether the performance meets the standard and preset performance requirements: Set the preset value of cooling / heating power as the basis for judging whether the performance meets the standard. For example, the preset cooling power should reach 1.8kW to meet the performance requirements. Performance judgment: Compare the calculated cooling / heating power with the preset value to determine whether the preset performance requirements are met.

[0083] Specific data example: At t=60s, the calculated cooling power is P=1.5kW, which does not reach the preset 1.8kW, so cooling needs to continue.

[0084] Continue or stop cooling / heating, control logic: If the preset performance requirements are not met, the cooling or heating operation will continue through the control system; if the preset performance requirements have been met or exceeded, the cooling or heating operation will be stopped through the control system. Operation execution: According to the control logic, send a command to continue or stop cooling / heating to the energy storage liquid cooling system to be tested.

[0085] Specific data example: Because the preset performance requirement is not met at t=60s, the control system sends a command to continue cooling. After a period of cooling operation, if the temperature drops further and the calculated cooling power reaches or exceeds 1.8kW, the control system sends a command to stop cooling.

[0086] 104. Generate a performance test report, which at least includes the working environment temperature, the working test fluid temperature and the total time to reach the preset performance requirements;

[0087] It should be noted that the preset performance requirements are set: the preset values ​​of cooling / heating power are clearly defined, for example, the cooling power reaches 2.0kW and the heating power reaches 1.8kW. Prepare the test environment: ensure that the test environment meets the test requirements, such as constant temperature and humidity. Install sensors: install temperature sensors in the test environment, and install temperature and flow sensors at key locations of the energy storage liquid cooling system to be tested.

[0088] Perform test and fill test fluid: Fill the energy storage liquid cooling system to be tested with test fluid, such as ethylene glycol water solution. Start test: Start the performance test through the control system and start recording time and sensor data at the same time. Continuous monitoring: During the test, continuously monitor and record the working environment temperature, working test fluid temperature and cooling / heating power.

[0089] Data recording and processing,Data recording: The data collected during the test is recorded in real time in the host control system.Data processing: The recorded data is processed, including the calculation of average temperature, flow rate and the total time required to achieve the preset performance requirements.

[0090] Specific data examples: Working environment temperature: 24°C at the beginning of the test, and the average temperature during the test is 25°C. Working test fluid temperature: 25°C at the beginning of cooling, and 16°C when the preset cooling power is reached; 25°C at the beginning of heating, and 34°C when the preset heating power is reached. Total time to reach the preset performance requirements: During cooling, it takes 120 seconds to reach the preset cooling power; during heating, it takes 150 seconds to reach the preset heating power.

[0091] Generate a performance test report. Report format: Select an appropriate report format, such as Word, Excel, or PDF. Report content: At least include the following information: test date, test environment description, preset performance requirements, actual test data (including working environment temperature, working test fluid temperature and change curve), total time to achieve preset performance requirements, and test conclusions. Data visualization: Add charts to the report, such as a curve chart of temperature changes over time, to more intuitively display the test results.

[0092] 105. Turn on the drainage function of the energy storage liquid cooling system to be tested, blow air into the pipeline, use the gas pressure to completely drain the residual test liquid in the pipeline, cut off all power and water sources of the test platform, and complete the performance test;

[0093] It should be noted that the drainage function should be turned on and the preparation before operation is as follows: Make sure the test has been completed and all test data has been recorded. Check whether the drainage valve of the energy storage liquid cooling system to be tested is in a working state.

[0094] Open the drainage valve: manually or automatically open all valves that need to drain water. For example, in this embodiment, we open three main drainage valves, numbered DV-1, DV-2, and DV-3.

[0095] Monitor the drainage process: Use a flow meter to monitor the drainage flow to ensure smooth drainage. For example, the initial drainage flow is 5L / min, and the flow gradually decreases as the residual test liquid decreases. Record the drainage start time (such as: 15:30) and end time (such as: 15:45), and the total drainage time is 15 minutes.

[0096] Blow air into the pipe to remove the residual test liquid and prepare the gas source: connect a high-pressure gas cylinder or air pump to ensure that the gas source pressure is stable and sufficient. For example, use a nitrogen cylinder with a pressure of 5 bar.

[0097] Blow air into the pipeline: Connect the air source to the air blowing interface of the energy storage liquid cooling system to be tested. Turn on the air source and continue to blow gas into the pipeline, using the gas pressure to push the residual test liquid in the pipeline to the drain. Monitor the gas flow and pressure during the blowing process to ensure safe operation.

[0098] Check the residual liquid discharge: Check whether the residual test liquid has been completely discharged by observing whether there is liquid flowing out of the drain port and whether the liquid flowing out is clear. For example, after blowing for 5 minutes, the liquid flowing out of the drain port becomes clear, indicating that the residual test liquid has been basically discharged.

[0099] Cut off all power and water sources on the test platform. Cut off power: turn off all power switches on the test platform in sequence, including the main power supply, control power supply, etc. For example, the main power switch numbered PS-1 and the control power switch numbered CS-2 were both turned off at 15:50. Cut off water source: close all valves related to the water source to ensure that the water source is completely cut off. For example, close the water inlet valve WV-1 and the water outlet valve WV-2. Safety check: check whether all power and water sources have been completely cut off to ensure that the test platform is in a safe state.

[0100] In the embodiment of the present invention, by embedding the test platform into the production line, automated performance testing is achieved, manual intervention is reduced, and production efficiency is improved; through comprehensive performance testing, potential performance problems can be discovered and handled in a timely manner, ensuring that each energy storage liquid cooling system shipped meets the performance requirements, thereby improving product quality; accurate performance testing can predict the performance of the product in actual use, reducing the subsequent maintenance and replacement costs caused by performance problems; real-time monitoring and exception handling mechanisms during the test process can timely discover and respond to potential safety risks, thereby enhancing the security of the system; the generated performance test report provides rich data support, helping companies make more informed product development and market strategy decisions; products that have undergone rigorous performance testing can provide more stable and reliable performance, thereby improving the user experience.

[0101] Another embodiment of the performance testing method of the embedded energy storage liquid cooling system production line in the embodiment of the present invention includes:

[0102] 201. The test platform is completely embedded in the production line, and the circuit communication, water communication and gas communication between the test platform and the energy storage liquid cooling system to be tested are controlled by the host computer of the test platform;

[0103] Specifically, the circuit communication adopts an industrial-grade communication protocol, and the host computer is responsible for the power management of the entire test platform, including power distribution during the test and power cut-off in an emergency; the waterway communication is controlled by PLC loop feedback, and the host computer adjusts the opening of the electronically controlled valve according to real-time flow data;

[0104] It should be noted that for circuit communication, the application of industrial-grade communication protocols: Modbus TCP / IP is selected as the circuit communication protocol because of its high stability, fast transmission speed and good compatibility. Through this protocol, the host computer can accurately control the power status of each part of the test platform. Power management system: The host computer is equipped with special power management software, which is responsible for the distribution of power during the test. For example, at the beginning of the test, the host computer sends instructions to the power distribution unit through Modbus instructions to provide a stable 220V AC power supply for the liquid cooling system to be tested. Emergency power cut-off mechanism: During the test, if the host computer detects any abnormality (such as excessive current, unstable voltage, etc.), it will immediately send a cut-off instruction to the power management module through the Modbus protocol to ensure that the relevant power supply is cut off within 50ms to prevent equipment damage or safety accidents.

[0105] Waterway communication, PLC loop feedback control: Siemens S7-1200 PLC is used as the core of waterway control, and sensors are used to monitor parameters such as flow, pressure and temperature in the waterway in real time. These data are converted into digital signals through the analog input module of the PLC for processing by the host computer. Host computer flow adjustment strategy: After the host computer receives the real-time flow data sent by the PLC, it calculates the optimal opening of the electronically controlled valve through an algorithm according to the preset test process and standards. For example, when the flow is lower than the set value, the host computer will send instructions to the PLC to gradually increase the opening of the electronically controlled valve until the flow reaches the preset value.

[0106] Data recording and alarm mechanism: The host computer software has a data recording function, which can save the waterway communication data of each test. At the same time, if there is an abnormal situation in the waterway (such as a sudden decrease in flow, a sudden increase in pressure, etc.), the host computer will immediately trigger the alarm mechanism and notify the operator to handle it in time.

[0107] Gas circuit communication, gas circuit monitoring and control: For test links involving gas circuit communication, such as pneumatic valves or sensors used in liquid cooling systems, PLC is also used for monitoring and control. The gas circuit status is monitored in real time through equipment such as pressure sensors and flow switches installed on the gas circuit. Upper computer gas circuit management: The upper computer precisely controls the gas circuit according to test requirements. For example, when the pneumatic valve needs to be opened, the upper computer sends a command to the PLC, and the PLC controls the corresponding solenoid valve to open or close the valve. Safety and energy-saving measures: To ensure the safety of gas circuit communication, multiple protection mechanisms are integrated into the upper computer software, such as automatic pressure relief for excessive pressure and automatic alarm for gas leakage. At the same time, by optimizing algorithms and control strategies, the energy consumption of the gas circuit can be effectively reduced.

[0109] Specifically, wireless sensors are used to monitor ambient temperature and flow data in real time, and the data is transmitted to the host computer of the embedded system for processing. During the data processing, a filtering algorithm is used to eliminate interference signals generated during the test process to ensure the accuracy of the data; a heat exchanger is set near the production line to preheat or precool the test liquid using waste heat or cold energy generated by other equipment; and / or the heat exchanger stores the recovered heat or cold energy for use in other production links or equipment; multiple heat exchange areas are set in the test liquid flow pipeline, and each area is independently adjusted according to real-time data to improve local efficiency without increasing the overall preheating or precooling time. The heat transferred by the i-th heat exchange area is set to Q i ,but:

The overall energy efficiency of the system can be improved by optimizing the heat transfer coefficient, heat transfer area and temperature difference of each heat exchange area, and adjusting the magnetic field and / or electric field strength.

[0120] It should be noted that the filling of the test liquid and environmental monitoring, filling the test liquid: choose ethylene glycol aqueous solution as the test liquid because it has good thermal stability and thermal conductivity. Through the automatic filling system, the test liquid is filled into the energy storage liquid cooling system to be tested to a preset capacity, such as 50L. Environmental monitoring: wireless temperature sensors and flow sensors are arranged near the production line to monitor the ambient temperature (such as 25°C) and the test liquid flow (such as 2L / min) in real time. The data is transmitted wirelessly to the embedded system for processing.

[0121] Data processing and filtering, data reception: The embedded system receives real-time data from sensors, including ambient temperature and flow rate. Filtering algorithm: A moving average filtering algorithm is used to process the received data to eliminate interference signals that may be generated during the test and ensure the accuracy of the data. For example, the average of the most recent 10 data points is taken as the current valid data.

[0122] Heat exchanger setting and preheating / precooling, heat exchanger location: Set up a heat exchanger near the production line to preheat or precool the test liquid using waste heat (such as 60°C hot water) or cold energy (such as 10°C cold water) generated by other equipment. Heat recovery and storage: The heat exchanger stores the recovered heat or cold energy in a heat storage tank for use in other production links or equipment, achieving efficient use of energy.

[0123] Heat exchange area adjustment and local efficiency improvement, heat exchange area division: set multiple heat exchange areas (such as 3 areas) in the test liquid flow pipeline, and each area is independently adjusted according to real-time data. Heat transfer parameter setting: set the heat transfer coefficient U of each area i (For example, U1=50W / (m 2 ·K), U2=70W / (m 2 ·K), U3=60W / (m 2 ·K)) and heat transfer area (A1=1.0m 2 ,A2=0.6m 2 ,A2=0.8m 2 ) and temperature difference (like =10K, =15K, =20K).

[0124] Local efficiency calculation: According to the formula (Pick = 1s), calculate the heat Q transferred to each area i , and improve local efficiency by independently adjusting the parameters of each region.

[0125] Magnetic field / electric field heating / cooling device design: Device design: Design a device with a magnetic field and / or electric field to achieve rapid heating or cooling of the test fluid by adjusting the magnetic field strength B (such as 0.5T) and / or the electric field strength E (such as 1000V / m). Power calculation: According to the formula (Take k = 1, =0.1S / m, =1H / m), calculate the cooling power of magnetic field / electric field By adjusting E and / or B, rapid heating or cooling of the test liquid can be achieved.

[0126] Comprehensive energy efficiency ratio evaluation: Data summary: Summarize the total heat transferred by all heat exchange areas , System input power (such as 1000W) and magnetic field / electric field heating / cooling power .

[0127] Energy efficiency ratio calculation: According to the formula:

[0128]

[0129] Calculate the comprehensive energy efficiency ratio EER. Improve the overall energy efficiency of the system by optimizing the heat transfer parameters of each heat exchange area and adjusting the magnetic field / electric field strength.

[0130] This embodiment describes in detail how to achieve efficient and accurate performance testing in the performance test of the embedded energy storage liquid cooling system production line through steps such as filling test liquid, environmental monitoring, data processing, heat exchanger setting, heat exchange area adjustment, magnetic field / electric field heating / cooling device design and comprehensive energy efficiency ratio evaluation.

[0131] 203. Collect temperature and flow data of the energy storage liquid cooling system to be tested during the cooling or heating process, and calculate the cooling / heating power, and determine whether the preset performance requirements are met according to the cooling / heating power. If the preset performance requirements are not met, continue cooling or heating, and if they are met, stop cooling or heating;

[0132] Specifically, based on the physical characteristics of the energy storage liquid cooling system, a dynamic thermodynamic model is established. The model can dynamically calculate the cooling capacity or heating capacity according to the temperature and flow data collected in real time. The test platform is used to install a water flow sensor 1 and a temperature sensor 2 in the circulating water outlet pipe of the liquid cooling unit, which are used to measure the mass flow rate of the test liquid in the refrigeration / heat cycle respectively. And the temperature after cooling / heating A temperature sensor 1 is installed in the test platform for the circulating water inlet pipe of the liquid cooling unit to measure the temperature of the test liquid before cooling / heating ;According to the actual ambient temperature and atmospheric pressure, the specific heat capacity of the test liquid is obtained ;

[0133] The actual cooling / heating power :

[0134]

[0135] If the actual cooling / heating power Standard cooling / heating power with liquid cooling unit The absolute value of the difference between If it is equal to the set value K, it is considered to have met the preset performance requirements.

[0136] It should be noted that, in preparation for data collection, water flow sensor 1 and temperature sensor 2 are installed in the pipe of the liquid cooling unit circulating water out. Temperature sensor 1 is installed in the pipe of the liquid cooling unit circulating water in. The sampling frequency of water flow sensor 1 and temperature sensor (1 and 2) is set to 1 time per second.

[0137] Real-time data acquisition, start the test, and record the test liquid mass flow measured by water flow sensor 1 ,For example = 0.5 kg / s. At the same time, record the temperature T1 of the test liquid before cooling / heating measured by temperature sensor 1, for example, T1 = 25°C. Record the temperature T2 of the test liquid after cooling / heating measured by temperature sensor 2, for example, T2 = 15°C.

[0138] Environmental parameters are obtained. According to the actual ambient temperature (e.g., 25°C) and atmospheric pressure (e.g., 101.3 kPa), the specific heat capacity C of the test liquid (50% ethylene glycol aqueous solution) is obtained, for example, C = 3.281 kJ / (kg·K).

[0139] Cooling / Heating Power Calculation: Application Formula Calculate actual cooling / heating power.

[0140] Substituting the above data into the formula, we get = 3.281 kJ / (kg·K) × 0.5 kg / s × |15℃ -25℃| = 16.405 kW.

[0141] Performance requirement judgment: Set the standard cooling / heating power of the liquid cooling unit is 16 kW. Set the allowable difference K to 0.5 kW. Calculate and The absolute value of the difference between |16.405 kW - 16 kW| = 0.405 kW. Since 0.405 kW is less than the set value K (0.5 kW), it is judged that the actual cooling / heating power has reached the preset performance requirement.

[0142] When the test is finished or continued, the test platform will stop the cooling or heating process since the preset performance requirements have been met. If the preset performance requirements have not been met, the test platform will continue cooling or heating and repeat the steps until the conditions are met.

Statistical distribution analysis: calculate the skewness and kurtosis indicators of the data to provide an intuitive display of the data distribution form. For example, the skewness of the working environment temperature is 0.5 and the kurtosis is 3.2, indicating that the data distribution is slightly right-leaning and relatively concentrated; the skewness of the working test fluid temperature is -0.3 and the kurtosis is 2.8, indicating that the data distribution is slightly left-leaning and relatively flat.

[0152] Determination and prediction of the total time required to achieve the preset performance requirements: Actual total time: Based on the timing data of the host computer, determine the actual total time required for the energy storage liquid cooling system to achieve the preset performance requirements from the start of work. For example, the actual total time is 300 seconds. Predicted total time: Use the performance target prediction model and the model parameters obtained by fitting historical data for prediction. The model parameters are set to have been obtained by fitting historical data, and the characteristic variables that affect performance targets include the working environment temperature, the working test fluid temperature, and the system power. The predicted total time is calculated according to the prediction formula. For example, the predicted total time is 290 seconds.

[0153] Multi-parameter evaluation model and performance score calculation: Weight coefficient setting: Set the weight coefficient according to the importance of each parameter to the performance evaluation , , For example, setting =0.3, =0.4, =0.3.

[0154] Reference value setting: Set the reference temperature and time values ​​used for normalization. For example, =30℃, =50℃, =360 seconds.

[0155] Performance score calculation: Calculate the performance score based on the formula of the multi-parameter evaluation model Substitute the above data into the formula to get a specific performance score. For example, =0.85 (indicating good performance).

[0156] Performance test report generation and interactive chart display: Report generation: Generate a performance test report containing information such as the working environment temperature, working test fluid temperature, and the total time to reach the preset performance requirements based on the performance score and preset scoring criteria (such as excellent, good, qualified, unqualified, etc.). Interactive chart display: Use real-time updated curve charts to display temperature changes and flow fluctuations during the test; use thermal maps to display performance differences under different test conditions. These charts help to intuitively understand the system's performance status and optimization direction.

Learning algorithm application: Introduce machine learning algorithms to learn based on historical drainage data (such as gas pressure, drainage time, etc.) and optimize pressure control strategies. Specific data: It is set that during multiple drainage processes, the algorithm learns that the drainage effect is best when the gas pressure is 0.2 MPa, and the system will automatically adjust to this pressure value during subsequent drainage processes.

[0161] Branch pipe design and fluid mechanics simulation: Design optimization: Adopt branch pipe design to increase the contact area between gas and test liquid.

[0164] Double confirmation mechanism, sound and light alarm: Before automatically cutting off the power and water supply, the system reminds the operator to confirm through sound and light alarm. SMS notification: At the same time, the system sends SMS notifications to the designated operator's mobile phone to ensure timely response. Specific data: The system records the timestamp of the SMS and the mobile phone number of the recipient, such as "2024-10-11 10:49:30 sent to 1234567890".

[0165] 206. The drainage function adopts a two-stage drainage design, including a high-level main drainage stage and a low-level auxiliary drainage stage, to ensure that the residual test liquid in the pipeline is completely discharged;

[0166] By adding a liquid cooling unit filling port at a lower vertical position as an auxiliary drain port, a small amount of residual test liquid remaining in the liquid cooling unit components is discharged from the unit filling port at a lower position to the open type covered liquid storage tank 2 embedded in the lower part of the assembly line table;

[0167] It should be noted that the design principle of the high-position main drainage stage is: a main drain outlet is set at the highest point of the liquid cooling system, and gravity is used to allow most of the test liquid to flow out naturally.

[0168] Operation steps: Open the valve of the main drain outlet. Monitor the outflow of the test liquid until the outflow rate slows down significantly.

Drainage time: from opening the valve to the outflow rate slowing down significantly, a total of 4 minutes. Discharged test liquid volume: about 95% of the total volume, that is, 47.5 liters (the total volume is set to 50 liters).

[0169] Low-level auxiliary drainage stage, design principle: an auxiliary drain port is set at a lower vertical position of the liquid-cooled unit to discharge a small amount of test liquid remaining in the unit components.

[0170] Operation steps: After the main drainage stage is over, close the main drain valve. Open the auxiliary drain valve to drain the remaining test liquid into the liquid storage tank. Observe the outflow of the auxiliary drain until no liquid flows out.

[0171] Specific data: Auxiliary drain port location: bottom of the liquid cooling unit, vertical height 0.3 meters. Liquid storage tank location: embedded in the lower part of the assembly line table, connected to the auxiliary drain port.

Discharge test liquid volume: about 5% of the total volume, that is, 2.5 liters (the total volume is set to 50 liters, and 47.5 liters have been discharged in the main drainage stage).

[0172] Summary and effect evaluation, drainage effect: Through the two-stage drainage design, the residual test liquid in the pipeline was successfully discharged completely, ensuring the accuracy of the performance test and the smooth progress of the next round of tests. Time efficiency: The entire drainage process took a total of 5 minutes (4 minutes for the main drainage stage + 1 minute for the auxiliary drainage stage), which improved the drainage efficiency compared to the single drainage method. Safety: By setting up auxiliary drainage ports and liquid storage tanks, the test liquid is prevented from flowing randomly on the production line, improving the safety of the working environment.

[0174] The above describes the performance test method of the embedded energy storage liquid cooling system production line in the embodiment of the present invention. The following describes the test platform of the embedded energy storage liquid cooling system production line in the embodiment of the present invention. Figure 3 In the embodiment of the present invention, the test platform of the production line of the embedded energy storage liquid cooling system is composed of a power supply, a test platform host computer, a data acquisition module, a test platform main line, a liquid storage tank 1 and a liquid storage tank 2. Among them, the power supply is used to provide power guarantee for the test platform and the test liquid cooling unit. During the test process, the test platform must be connected to the test liquid cooling unit through the test platform main line, wherein the test platform main line includes a water line and a gas line. The test platform host computer is used to control the circuit, water line and gas line communication between the test platform and the test liquid cooling unit according to the relevant data measured by the data acquisition module. The data acquisition module mainly includes a temperature sensor and a flow sensor. In addition, the main function of the liquid storage tank 1 is to receive the test liquid that flows out of the tap and is purified, as well as the test liquid discharged from the main drainage stage of the liquid cooling unit, and the main function of the liquid storage tank 2 is to receive the residual test liquid discharged from the auxiliary drainage stage of the liquid cooling unit. Figure 4 The schematic diagram of the working principle of the product designed in this scheme is shown. The specific working principle and related components are introduced as follows:

[0175] 1) Filling and replenishing liquid: The production line workers install the corresponding test platform pipes at the water outlet, water inlet and liquid injection port of the liquid cooling unit respectively (Note: In order to facilitate the movable and visual operation of the installation process, the connecting pipes between the water inlet, outlet and liquid injection port of the liquid cooling unit and the open-type covered liquid storage tanks 1, 2 and the charging pipe of the test platform are all transparent plastic pipes). The open-type covered liquid storage tank 1 is fixed on the top of the assembly line to receive and store the test liquid discharged from the copper tap water pipe and filtered by the filter (filtration requirement: filter out substances with a diameter greater than 0.0001 microns). If the test process does not require high water quality for the test liquid, the tap water can also be allowed to flow directly into the open-type covered liquid storage tank 1 by opening the electric control valve 8. The open type covered liquid storage tank 1 is equipped with a liquid level switch, which is used to detect the water level of the liquid storage tank 1 and automatically control the liquid storage tank to fill the test liquid into the liquid cooling unit and replenish the liquid storage tank 1 (when the liquid level in the water tank 1 is higher than the preset liquid level, the liquid level switch automatically opens the filling port of the liquid cooling unit, and the upper computer of the test platform detects the filling port opening signal and closes the electronically controlled valves 2, 3 and 6 and opens the electronically controlled valves 1, 4 and 5, and the liquid storage tank 1 starts to fill the liquid cooling unit; when the liquid level in the liquid storage tank 1 is lower than the preset liquid level, the liquid level switch automatically opens the tap water switch of the liquid storage tank 1 and opens the electronically controlled valves 1, 4 and 5 during operation). The control screen displays the refill start signal and the filter selection signal. If filtered tap water is required for testing, the production line worker needs to press the filter button. After the test platform host computer detects that the tap water switch is turned on and the filter signal is displayed, it will close the electric control valve 8, open the electric control valve 7 and the water pump, and the liquid storage tank 1 will start to replenish filtered tap water. If unfiltered tap water is required for testing, the production line worker needs to press the non-filter button. After the test platform host computer detects that the tap water switch is turned on and the non-filter signal is displayed, it will open the electric control valve 8 and the electric control valve 7, and the liquid storage tank 1 will start to replenish tap water.).

[0176] 2) Collect ambient temperature data and determine the type of start-up function of the liquid cooling unit: According to the ambient temperature meter installed on the test platform, automatically determine whether to start the cooling or heating function of the test liquid cooling unit. The test liquid in the liquid storage tank 1 is filled into the liquid cooling unit from the low-level opening. The low-level opening of the water tank is equipped with a copper filling water pipe with a diameter of 25 mm to fill the test liquid into the liquid cooling unit. During the cooling process of the liquid cooling unit, the copper filling water pipe will continuously add test liquid of suitable temperature to the water pump, condenser and other components of the unit. After the cooling / heating cycle, the test liquid will flow to the water outlet of the liquid cooling unit, and then flow back to the open covered liquid storage tank 1 at the top of the production line through the transparent plastic pipe at the connection section between the unit and the test platform and the copper return pipe with a diameter of 20 mm. In addition, the filling water pipe is also equipped with a temperature sensor and a 380V / 15kW electric heater. When the ambient temperature is lower than the allowable operating temperature of the battery pack (generally 5°C, which needs to be set according to the type of energy storage system, battery technology, and application scenario), the liquid cooling unit needs to turn on the heating function to heat the test fluid; when the unit detects that the test fluid level is high enough, the control screen of the test bench will display a reminder signal for the start of the test. The production line workers only need to press the cooling / heating key on the control screen, and the liquid cooling unit will immediately start cooling / heating work, and preset the cooling / heating capacity of the test liquid cooling unit through the control screen, so that the console can control the test fluid flow in real time. Here, the console uses the PLC loop feedback control principle to control the test fluid flow in real time. The input of the test fluid flow is continuously adjusted through the control loop until the controlled variable (the absolute value of the difference between the actual cooling / heating power and the standard cooling / heating power of the liquid cooling unit, that is: ) is close to or equal to the set value (the set value is: 1x10 -5 W), the system reaches a new stable state, and the control loop can determine that the test unit has met the performance test requirements and send this signal to the test platform host computer. When the test platform host computer receives the signal that the unit meets the test performance, it will send a stop signal to the production line workers through the control panel. The production line workers can press the stop test button on the control panel to stop the test. (Basic principle of cooling / heating capacity calculation: The test platform is used for the circulating water outlet pipe of the liquid cooling unit. Water flow sensor 1 and temperature sensor 2 are installed to measure the mass flow rate of the test liquid in the cooling / heating cycle. (Unit: kg / s) and temperature after cooling / heating (Unit: °C), a temperature sensor 1 is installed in the pipe for circulating water in the liquid cooling unit on the test platform to measure the temperature of the test liquid before cooling / heating (Unit: °C), and then according to the actual ambient temperature and atmospheric pressure, the specific heat capacity of the test liquid is obtained by looking up the table (Unit: J / (kg・℃)), the corresponding cooling power can be calculated (Unit: W).

[0177] 3) Drainage of liquid cooling unit: When the test platform receives the "stop test" signal from the control console, the host computer of the test platform will send an electrical signal to open the electronically controlled valve in the air pipe and start draining the liquid cooling unit. The copper air pipe with a diameter of 20 mm is provided with an opening regulator to control the air flow rate blown into the air pipe according to the signal detected by the pressure sensor on the air pipe, so as to completely drain the residual test liquid in the liquid cooling unit. In the drainage design scheme of this scheme, the method of blowing and draining is adopted. By blowing air into the pipe, the residual liquid in the pipe is discharged by gas pressure. In the design of the gas and liquid circuits, multiple gas and liquid common pipelines are adopted, and the automatic control of the gas and liquid circuits is realized by electronically controlled valves. The air blown in by the air pipe mainly enters the condenser, water pump and other components of the unit from the water inlet of the liquid cooling unit, and then flows out from the water outlet of the liquid cooling unit. Finally, the test liquid remaining in the unit flows back to the tank from the water outlet of the liquid cooling unit along the pipeline through the opening at the high position of the open-type covered liquid storage tank 1 for reuse. Since the main drainage pipeline is to use air pressure to return the residual test liquid in the liquid cooling unit to the open covered liquid storage tank 1 at the top of the assembly line, the water tank is located at a high position, which is prone to incomplete drainage. In order to solve this problem, this solution also uses the liquid cooling unit filling port located at a lower vertical position as an auxiliary drainage port, allowing a small amount of residual test liquid remaining in the liquid cooling unit components to be discharged from the low-position unit filling port to the open covered liquid storage tank 2 embedded in the lower part of the assembly line table. For the liquid cooling unit drainage step, the specific control process of the control console is as follows: when the test platform receives the "stop test" signal sent by the test platform host computer, the test platform host computer will send an electrical signal to open the electric control valve in the air pipe, and close the electric control valves 1, 3 and 6, open the electric control valves 2, 4 and 5, and the test platform starts the main drainage stage. When the water volume sensor 2 in the water outlet pipe measures the water flow rate to be zero, the control console receives the zero flow rate signal from the water volume sensor 1 and sends an electrical signal to control the opening of the electronically controlled valves 3 and 6, and the closing of the electronically controlled valves 2 and 4. The test platform starts the auxiliary drainage stage. At this time, the only small amount of residual test liquid remaining in the liquid cooling unit will flow from the liquid cooling unit filling port to the open liquid storage tank 2 with a lid.

[0178] 4) End of test: When the water flow rate measured by the water flow sensor 2 near the liquid injection port is zero, it can be determined that the residual test liquid in the liquid cooling unit has been completely drained. The test platform host computer receives the signal from the water flow sensor 3 and will send a "drainage end" signal to the production line workers by displaying the drainage end information on the control screen. The production line workers press the drainage end button on the control screen to automatically generate a performance test report (the performance test report will at least display the following parameters: working environment temperature, working test liquid temperature, and the total time to meet the corresponding performance requirements). Then all power and water sources of the entire test platform are automatically cut off, and the production line workers can remove the pipes installed at the water outlet, water inlet and liquid injection port of the liquid cooling unit, and the entire refrigeration / thermal performance test process is completed.

[0179] Reference Figure 2 The test process of the performance test platform of the embedded energy storage liquid cooling system production line designed in this scheme is as follows: connect the performance test platform and the test unit -> determine whether filtering is required according to the water quality requirements of the test liquid -> if there is a filtering requirement, automatically determine and fill the filtered test liquid into the liquid storage tank according to the water volume storage situation of the liquid storage tank; if there is no filtering requirement, automatically determine and fill the liquid storage tank with unfiltered test liquid according to the water volume storage situation of the liquid storage tank -> automatically determine the test performance type according to the ambient temperature data and turn on the corresponding performance -> automatically collect temperature and flow data, calculate the cooling / heating capacity and determine whether the performance requirements are met -> if not met, continue cooling / heating; if met, terminate cooling / heating -> stop performance testing -> automatically start the test unit to drain -> determine that the drainage is complete -> if the drainage is complete, automatically generate a performance test report and cut off all water and power sources of the performance test platform; if the drainage is not complete, continue drainage -> disconnect the performance test platform from the test unit.
