Description

Technical Field

[0001] The present application relates to the technical field of energy storage applications of aqueous liquid-filled batteries, and in particular to an automatic temperature-controlled, air-disturbance, constant-power charging energy storage system for aqueous liquid-filled batteries. Background Art

[0002] Aqueous flooded batteries, used as backup power sources in applications such as communication base stations and data center UPSs, are kept in a floating charge state for extended periods, allowing for constant diffusion of electrolyte ions to maintain a uniform acid concentration. However, in energy storage applications, batteries require frequent charge / discharge cycles. This can lead to electrolyte stratification due to changes in electrolyte concentration, or specific gravity. As the number of charge / discharge cycles increases, the difference in electrolyte concentration between the top and bottom of the battery increases, particularly in taller batteries. This increasing electrolyte concentration at the bottom of the battery can damage the positive and negative plates. When operated in excessively high acid concentrations, the positive grid is susceptible to corrosion, while the negative plate is susceptible to irreversible sulfation, resulting in reduced battery capacity and charge acceptance. Furthermore, if the electrolyte is not adequately mixed, this can lead to uneven current distribution between the positive and negative plates, reducing the battery's charge acceptance.

[0042] Figure 1 This is a structural block diagram of an automatic temperature-controlled air-turbation constant-power charging energy storage system for a water-based liquid-filled battery according to an embodiment of the present application. Figure 1 As shown, the system includes: an air disturbance unit 1, a temperature adjustment unit 2, a collection module 3 and a control unit 4.

[0043] The air disturbance unit 1 is used to transport gas into the battery. The air disturbance unit 1 includes an air duct 15, which is vertically inserted into the battery and has a plurality of air holes on its surface for injecting gas into the electrolyte of the battery in the form of bubbles.

[0044] Figure 2 Schematic diagram of an automatic temperature-controlled air-turbation constant-power charging energy storage system for a water-based flooded battery according to an embodiment of the present application. Figure 2 As shown, the air disturbance unit includes an air compressor 11 , a gas purification device 12 , a gas storage tank 13 , a gas pipeline 14 , and an air guide pipe 15 .

[0045] Figure 3 is a schematic diagram of an airway according to an embodiment of the present application, such as Figure 3 As shown, a first rubber ring 151 is used to seal the air duct 15 and the battery cover. Gas enters the electrolyte through the air holes 152 on the air duct 15, stirring the electrolyte, reducing electrolyte stratification, and improving the consistency of electrolyte ion concentration. This ensures that active substances in different areas have the same reactivity, effectively improving the battery's charge acceptance, and thus enabling constant power charging of the battery.

[0046] In some embodiments, the air duct adopts a tapered contraction structure, the diameter of the air holes on the air duct gradually increases from top to bottom, and there is a distance between the end of the air duct and the bottom end surface of the battery.

[0047] The distance between the end of the air duct and the bottom end of the battery is within a preset range (e.g., 4-5 cm). The air duct penetrates deep into the electrolyte, ensuring a more even distribution of bubbles within the electrolyte and a better agitation effect. Preferably, the angle of the tapered contraction structure ranges from 15° to 30°.

[0048] The temperature regulating unit 2 is used to regulate the temperature of the gas input into the battery by the air disturbance unit.

[0049] The intake air temperature is regulated according to the battery temperature. When the battery temperature is too high, the intake air temperature is lowered for cooling, keeping the battery within the preset operating temperature range. It should be noted that the preset operating temperature range is the optimal operating temperature of the battery obtained experimentally. By controlling the operation of the aqueous flooded battery within the optimal operating temperature range, the consistency of the electrolyte ion concentration is improved, and the active materials in different regions have the same reaction activity, the battery's charge acceptance capacity is effectively improved, thereby achieving constant power charging of the battery.

[0050] The acquisition module 3 is used to collect the electrical parameters and temperature parameters of the battery.

[0051] Optionally, the battery's electrical parameters include voltage and current. In this embodiment, the battery's temperature parameters are collected using a temperature sensor. The collection module includes a temperature sensor module 31 and a temperature signal transmission harness 32.

[0052] In some embodiments, the acquisition module includes a temperature sensor built into the battery, and the temperature sensor is sealed with a corrosion-resistant sleeve. The sleeve material of the temperature sensor is selected from any one of PTFE, PP, ABS, PC-ABS, PPO, and PVC acid-resistant plastics.

[0053] The temperature sensor is sealed with a corrosion-resistant sleeve to prevent the temperature sensor probe from being corroded in acid for a long time.

[0054] Figure 4 Schematic diagram of a temperature sensor module according to an embodiment of the present application, such as Figure 4 As shown, the temperature sensor module 31 includes a second rubber ring 311 , a temperature sensor 312 , and a temperature sensor sleeve 313 .

[0055] The temperature of each battery in the battery cluster is collected, transmitted, and processed by the BMS. The battery's internal temperature sensor 312 and the end of the temperature sensor sleeve 313 are inserted approximately halfway up the battery casing's bottom height. The temperature sensor sleeve 313 is sealed to the battery cover by a second rubber ring 311. The temperature collected by the temperature sensor 312 is transmitted via the temperature signal transmission harness 32 to the BMS temperature signal processing unit 44, which processes the temperature signals for the entire battery cluster.

[0056] The control unit 4 is used to control the start and stop of the air disturbance unit according to the electrical parameters, as well as the gas pressure and gas flow inside the battery, and to control the temperature adjustment unit according to the temperature parameters to adjust the gas temperature.

[0057] The start and stop of the air disturbance unit 1 is triggered by the battery cluster SOC value or the battery cluster voltage value, and the start and stop of the temperature adjustment unit 2 is triggered by the output value of the BMS temperature signal processing unit 44.

[0058] The battery cluster SOC value or battery cluster voltage value is calculated through electrical parameters, and the air disturbance unit is activated according to the battery cluster SOC value or battery cluster voltage value. After constant power charging reaches the predetermined SOC threshold range or battery cluster voltage range, the air disturbance unit is turned off, and the gas pressure and gas flow rate input into the battery are controlled according to the battery's electrical parameters. This method improves the battery's energy conversion efficiency, reduces positive electrode corrosion and negative electrode sulfation, maintains battery capacity, reduces energy storage costs, reduces water decomposition, hydrogen, and oxygen emissions caused by overcharging, reduces acid mist emissions, and improves energy storage safety and environmental protection. Furthermore, through regular maintenance equalization and rehydration, the battery's cycle life can be extended.

[0059] Through the above system, the air disturbance unit 1 delivers gas to the interior of the battery. The air disturbance unit includes an air duct that is vertically inserted into the battery and has a plurality of air holes on its surface for injecting gas into the battery's electrolyte in the form of bubbles. The temperature control unit 2 adjusts the temperature of the gas input to the battery by the air disturbance unit. The acquisition module 3 collects the battery's electrical parameters and temperature parameters. The control unit 4 controls the start and stop of the air disturbance unit, as well as the gas pressure and gas flow input to the battery according to the electrical parameters, and controls the temperature control unit according to the temperature parameters to adjust the gas temperature, thereby solving the problems of low charging efficiency and short service life of aqueous flooded batteries. By controlling the temperature of the input gas to keep the battery temperature within an appropriate range, the consistency of the electrolyte ion concentration is improved, the active materials in different regions are ensured to have the same reaction activity, and the battery's charging acceptance capacity is improved, thereby achieving constant power charging of the battery. The air disturbance unit avoids electrolyte stratification, improves charging efficiency, and extends the battery's service life.

[0060] In some embodiments, the air disturbance unit 1 includes: an air compressor 11 , a gas purification device 12 , a gas storage tank 13 and a gas pipeline 14 .

[0061] The gas output end of the air compressor 11 is connected to the gas input end of the gas purification device 12 , the gas output end of the gas purification device 12 is connected to the gas input end of the gas storage tank 13 , and the gas output end of the gas pipeline 14 is connected to the gas input end of the gas guide pipe 15 .

[0062] The air compressor 11 is used to provide compressed air.

[0063] The gas purification device 12 is used to purify the compressed air provided by the air compressor.

[0064] The gas purification device 12 removes oil and water from the compressed air to prevent contamination of the electrolyte.

[0065] The air storage tank 13 is used to store the purified compressed air.

[0066] The gas pipeline 14 is used to transport compressed air to the interior of each battery.

[0067] The compressed air generated by the air compressor 11 passes through the gas purification device 12, the gas storage tank 13, the gas pipeline 14 and the gas guide pipe 15 in sequence and then enters the battery electrolyte, thereby delivering gas to the battery electrolyte.

[0068] In some embodiments, the gas output end of the gas storage tank 13 is connected to the gas input end of the temperature regulating unit 2, and the gas output end of the temperature regulating unit 2 is connected to the gas input end of the gas pipeline 14. The compressed air in the gas storage tank 13 enters the gas pipeline 14 after passing through the temperature regulating unit 2.

[0069] The temperature regulating unit 2 includes a cooling unit 21 and a heat exchanger 22 . The cooling unit 21 and the heat exchanger 22 work together to control the temperature of the compressed air within a preset intake temperature range.

[0070] The refrigerant outlet of the cooling unit 21 is connected to the refrigerant inlet of the heat exchanger 22, and the refrigerant return port of the cooling unit 21 is respectively connected to the refrigerant outlet of the heat exchanger 22. The compressed air is cooled by the heat exchanger. Preferably, the cooling temperature range of the cooling unit is 5-25°C.

[0071] The temperature control output value is used as a trigger to start or stop the cooling unit 21. For example, during charging, when the average internal temperature of the battery is higher than 30°C, the cooling unit 21 starts to cool the battery. When the average internal temperature of the battery is lower than 20°C, the cooling unit 21 automatically stops cooling the battery, keeping the battery within the optimal operating temperature range.

[0072] In some embodiments, the gas pipeline 14 includes a main gas pipeline, and a constant pressure reducing valve 41 is provided on the main gas pipeline. The constant pressure reducing valve 41 is used to control the pressure of the gas in the gas pipeline.

[0073] In some embodiments, the gas pipeline 14 includes a main gas pipeline, and a flow regulating valve 42 is provided on the main gas pipeline. The flow regulating valve 42 is used to control the gas flow in the gas pipeline.

[0074] In some embodiments, the system is used to control a battery cluster consisting of multiple aqueous flooded batteries, the electrical parameters are electrical parameters of the battery cluster, and the control unit 4 includes an analysis module and a solenoid valve 43 .

[0075] An analysis module is used to analyze electrical parameters to obtain a battery cluster SOC value or a battery cluster voltage value, and generate a solenoid valve control instruction according to the battery cluster SOC value or the battery cluster voltage value;

[0076] The solenoid valve 43 is used to respond to a solenoid valve control instruction to control the start and stop of the air disturbance unit.

[0077] The constant pressure reducing valve 41 regulates the intake pressure of the entire battery cluster, the flow regulating valve 42 regulates the gas flow of the entire battery cluster, and the solenoid valve 43 controls the start and stop of the gas disturbance system of the entire battery cluster.

[0078] In some embodiments, the analysis module includes:

[0079] The first analysis module is configured to generate a first control instruction when the battery cluster SOC value is greater than a first SOC threshold or the battery cluster voltage value is greater than a first voltage threshold, wherein the first control instruction is configured to control the solenoid valve to start the operation of the air disturbance unit.

[0080] After the battery cluster starts charging, the SOC value and voltage will gradually increase. When the SOC value or voltage is greater than a preset first threshold, the air disturbance unit is started.

[0081] The second analysis module is configured to generate a second control instruction when the battery cluster SOC value is greater than a second SOC threshold or the battery cluster voltage value is greater than a second voltage threshold, wherein the second control instruction is configured to control the solenoid valve to stop the air disturbance unit.

[0082] refer to Figure 2 The control unit also includes a BMS SOC calculation module 45 and a BMS voltage signal processing module 46. The acquisition module also includes a charging voltage acquisition harness 33. During constant power charging, the battery cluster SOC value or battery cluster voltage value is used as a trigger to activate or deactivate the air disturbance system.

[0083] Preferably, the second SOC threshold range is 90-95%, the second voltage threshold range is 2.4-2.45V / single*n strings, where n is the total number of batteries in the battery cluster, and the constant power charging power value is the battery's 2-10 hourly rate rated energy / charging time h.

[0084] For example, the maximum depth of discharge of the battery cluster is 75%. The battery cluster starts charging. When the battery cluster SOC value is greater than 30% or the battery cluster voltage reaches 2.15V / n string, the solenoid valve 43 automatically controls the air disturbance unit to start operation. When the battery cluster SOC value reaches 95% or the battery cluster voltage reaches 2.4V / single*n string, the solenoid valve 43 automatically controls the air disturbance system to stop operation, and charging stops at the same time, and the battery cluster jumps to the static or discharge stage.

[0085] Through this control strategy, the battery will not be overcharged during the charging process, which improves the battery's energy conversion efficiency and reduces water decomposition and acid mist emissions.

[0086] It should be noted that the above modules can be functional modules or program modules, and can be implemented through software or hardware. For modules implemented through hardware, the above modules can be located in the same processor; or the above modules can be located in different processors in any combination.

To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0088] The above-described embodiments merely represent several implementation methods of the present application.
