[0030] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0031] The energy storage power station early warning method and device according to the embodiment of the present application are described below with reference to the accompanying drawings.

[0032] Figure 1A flowchart of an energy storage power station early warning method provided in an embodiment of the present application.

[0033] like Figure 1 As shown, the energy storage power station early warning method includes the following steps:

[0034] Step 101, determining a first warning judgment result corresponding to each battery cell in the energy storage power station, a second warning judgment result corresponding to each battery pack, a third warning judgment result corresponding to each battery cluster, and a fourth warning judgment result corresponding to each battery compartment.

[0035] Among them, the energy storage power station is composed of multiple battery compartments, each battery compartment is composed of multiple battery clusters, each battery cluster is composed of multiple battery packs, and each battery pack is composed of multiple battery cells.

[0036] The first warning judgment result may be used to indicate that a warning is not required, or may be used to indicate that a warning is required and the corresponding first warning reason.

[0037] In some embodiments, the first warning judgment result corresponding to each battery cell is determined according to the health state SOH and / or internal resistance of each battery cell.

[0038] In some embodiments, the voltage, current, temperature and other parameters of the battery cell can be monitored, combined with historical data, and the health status of the battery cell, such as capacity attenuation and internal resistance change, can be predicted through big data analysis.

[0039] In some embodiments, the performance and aging of the battery cell can be evaluated by measuring the change in internal resistance of the battery cell under different charge and discharge states.

[0040] In some embodiments, when the health status of the battery cell exceeds the normal range and the internal resistance of the battery cell is normal, the first early warning judgment result indicates a warning, and the warning reason is that the battery cell is unhealthy; when the health status of the battery cell is normal and the internal resistance of the battery cell exceeds the normal range, the first early warning judgment result indicates a warning, and the warning reason is battery cell aging; when the health status of the battery cell exceeds the normal range and the internal resistance of the battery cell exceeds the normal range, the first early warning judgment result indicates a warning, and the warning reason is battery cell aging and unhealthy battery cells.

[0041] In some embodiments, the second warning judgment result corresponding to each battery pack may be determined based on the charging current change data and / or the first temperature change data corresponding to each battery cell in each battery pack.

[0042] It should be noted that by monitoring the charging current changes of each cell in the battery pack and analyzing the current fluctuations during the charging process, the charging efficiency and safety of the battery pack can be predicted.

[0043] It should be noted that, by combining the first temperature change data of each battery cell in the battery pack, the heat dissipation performance and thermal stability of the battery pack can be evaluated to prevent the risk of overheating.

[0044] The second warning judgment result can be used to indicate no warning, or to indicate the need for warning and the corresponding second warning reason. The second warning reason can be low charging efficiency of the battery pack, and / or poor heat dissipation performance, poor thermal stability.

[0045] In some embodiments, the third warning judgment result corresponding to each battery cluster may be determined according to the charging cut-off voltage corresponding to each battery cell in each battery cluster and / or the second temperature change data corresponding to the insulated gate bipolar transistor element.

[0046] It should be noted that monitoring the charge and discharge cut-off voltage of each cell in the battery cluster can ensure voltage consistency and prevent performance degradation and safety hazards caused by voltage differences.

[0047] It should be noted that real-time monitoring of the second temperature change data corresponding to the insulated gate bipolar transistor element IGBT in the battery cluster can prevent damage and failure caused by overheating.

[0048] Among them, the third warning judgment result includes the second temperature change data, whether the second temperature change data is abnormal, and whether the charging cut-off voltage is abnormal.

[0049] In some embodiments, the fourth warning judgment result corresponding to each battery compartment can be determined based on the temperature field corresponding to each battery compartment and the third temperature change data corresponding to the transformer of each battery compartment.

[0050] In some embodiments, a temperature sensor in the battery compartment may be used to construct a temperature field corresponding to the battery compartment.

[0051] It should be noted that real-time monitoring of the temperature distribution and change trend of the temperature field corresponding to the battery compartment can prevent local overheating. Monitoring the third temperature change data of the transformer in the battery compartment can analyze the temperature rise trend of the transformer and ensure that the transformer operates within a safe temperature range.

[0052] Among them, the fourth early warning judgment result may include the third temperature change data, the temperature field, whether the temperature field is locally overheated, and whether the third temperature change data is abnormal.

[0053] Step 102, determining the target battery compartment, target battery cluster, target battery pack, and target battery cell to be warned based on the first warning judgment result, the second warning judgment result, the third warning judgment result, and the fourth warning judgment result.

[0054] In some embodiments, the battery cell indicated by the first warning judgment result as the warning can be determined as the target battery cell, the battery pack where the target battery cell is located and the battery pack indicated by the second warning judgment result as the warning can be determined as the target battery pack, the battery cluster where the target battery pack is located and the battery cluster indicated by the third warning judgment result as the warning can be determined as the target battery cluster, and finally the battery compartment where the target battery cluster is located and the battery compartment indicated by the fourth warning judgment result as the warning can be determined as the target battery compartment.

[0055] Thus, it is possible to determine the battery pack, battery cluster, and battery compartment where the warned battery cell is located; the battery cluster and battery compartment where the warned battery pack is located; and the battery compartment where the warned battery cluster is located.

[0056] Step 103 , displaying a warning in a display interface according to the target battery compartment, the target battery cluster, the target battery pack and the target battery cell.

[0057] In some embodiments, after the target battery compartment, the first mark corresponding to each battery compartment in the energy storage power station is displayed in the display interface, wherein the first mark corresponding to the target battery compartment is displayed differently from the first mark corresponding to the non-target battery compartment. This can help the staff to quickly and conveniently determine which battery compartment has an alarm, so as to further check the cause of the battery compartment alarm.

[0058] The non-target battery compartments are other battery compartments in the energy storage power station except the target battery compartment. For example, the first mark of the non-target battery compartment can be displayed in black, and the first mark corresponding to the target battery compartment can be displayed in red.

[0059] In some embodiments, when the first mark corresponding to any target battery compartment is selected, the fourth warning judgment result corresponding to any target battery compartment and the second mark corresponding to each battery cluster in any target battery compartment are displayed in the display interface, wherein the display style of the second mark corresponding to the target battery cluster is different from that of the second mark corresponding to the non-target battery cluster. This can help the staff to quickly and conveniently determine which battery cluster has a warning, so as to further check the cause of the battery cluster warning.

[0060] In some embodiments, the staff can determine any target battery compartment by clicking the first mark corresponding to the target battery compartment with the mouse, or by the first mark corresponding to the target battery compartment in the touch display interface, or by voice commands, such as "check any target battery compartment", to determine any target battery compartment.

[0061] In some embodiments, when the fourth warning judgment result corresponding to any target battery compartment indicates a warning, the display interface also displays the fourth warning reason corresponding to any target battery compartment and the corresponding fourth operation and maintenance suggestion. This can quickly help the staff to identify the warning reason of the target battery compartment and give operation and maintenance suggestions, so as to timely inspect and repair the target battery compartment and improve the safety and work efficiency of the energy storage power station.

[0062] For example, when the fourth warning cause includes local overheating of the temperature field, the corresponding fourth operation and maintenance suggestions include: it is recommended to conduct on-site inspection, use an infrared thermometer to detect the temperature of the battery compartment and compare it with the temperature field; tighten the positive and negative battery terminals in the local overheating area; check the battery temperature probe and temperature measurement circuit; continuously monitor the temperature in the overheating area to observe whether the temperature deviates further from the normal value; fill in the defect record and fill in the maintenance plan. It is recommended to check the working status of the air conditioner to see if there is any abnormal sound or vibration, and the indoor temperature and humidity are within the set range; it is recommended to check the internal and external air filters (nets) of the air conditioner to be clean and intact.

[0063] For example, when the fourth warning reason includes abnormal third temperature change data of the transformer, the corresponding operation and maintenance suggestions include: it is recommended to check the working status of the air cooling device and the working power supply of the fan; check whether the inlet and outlet air ducts and air duct filters are blocked; check the indication values ​​of multiple temperature measurement points on the transformer body; operate to reduce the power output of the transformer; strengthen temperature inspections during daily inspections and fill in inspection records; adjust the energy storage system shutdown plan and conduct internal inspections of the transformer; repair the transformer according to the operating procedures and disconnect the electrical connections in the energy storage system; use an infrared thermometer to check the temperature of the transformer; fill in defect records and report maintenance plans.

[0064] In some embodiments, a curve graph corresponding to the third temperature change data corresponding to any target battery compartment may also be displayed in the display interface. When the third temperature change data is abnormal, the title of the curve graph is displayed in red.

[0065] Figure 2 A schematic diagram of a display interface provided by an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the display interface includes first identifiers corresponding to 21 battery compartments of the energy storage power station, among which compartments 9 and 12 are target battery compartments. When compartment 9 is selected, a second identifier corresponding to 10 battery clusters included in compartment 9 is further displayed in the display interface, among which clusters 3 and 8 are target battery clusters. Figure 2 The right side of the figure is a graph of the third temperature change data corresponding to the transformer in compartment 9. Figure 2 The lower left corner of the screen displays the cause of the warning and operation and maintenance suggestions.

[0066] In some embodiments, when the second identifier corresponding to any target battery cluster in the display interface is selected, the third warning judgment result corresponding to any target battery cluster and the third identifier corresponding to each battery pack in any target battery cluster are displayed in the display interface, wherein the display style of the third identifier corresponding to the target battery pack is different from that of the third identifier corresponding to the non-target battery pack. Thus, it can not only help the staff to quickly lock the third warning judgment result corresponding to any selected target battery cluster, but also help the staff to quickly and conveniently determine which battery pack has a warning, so as to further check the cause of the battery cluster warning.

[0067] In some embodiments, the staff can determine any target battery cluster by clicking the second identifier corresponding to the target battery cluster with a mouse, or by touching the second identifier corresponding to the target battery cluster in the display interface, or by voice commands, such as "check any target battery compartment", to determine any target battery cluster.

[0068] In some embodiments, when the third warning judgment result corresponding to any target battery cluster indicates a warning, the display interface also displays the third warning reason corresponding to any target battery cluster and the corresponding third operation and maintenance suggestion. This can quickly help the staff to identify the warning reason of any target battery cluster and give operation and maintenance suggestions, so as to timely inspect and repair the target battery cluster and improve the safety and work efficiency of the energy storage power station.

[0069] For example, when the third warning reason includes abnormal second temperature change data corresponding to the IGBT, the third operation and maintenance suggestion may include: checking the indication values ​​of multiple temperature measurement points on the IGBT body; operating to reduce the power output of the IGBT; strengthening temperature inspections during daily inspections and filling in inspection records; repairing the IGBT according to operating procedures; filling in defect records and submitting maintenance plans.

[0070] For example, when the third warning reason includes abnormal charging cut-off voltage, the third operation and maintenance suggestion may include: promptly using a multimeter to measure the battery cell voltage for comparison and inspection, and replacing or recharging the battery cell according to the actual situation.

[0071] In some embodiments, a curve graph corresponding to the second temperature change data corresponding to any target battery cluster may also be displayed in the display interface. When the second temperature change data is abnormal, the title of the curve graph is displayed in red.

[0072] In some embodiments, when the third identifier corresponding to any target battery pack in the display interface is selected, the second warning judgment result corresponding to any target battery pack and the fourth identifier corresponding to each battery cell in any target battery pack are displayed in the display interface, wherein the display style of the fourth identifier corresponding to the target battery cell is different from that of the fourth identifier corresponding to the non-target battery cell. In this way, it can not only help the staff to quickly lock the second warning judgment result corresponding to any selected target battery pack, but also help the staff to quickly and conveniently determine which battery cell has a warning, so as to further check the cause of the battery pack warning.

[0073] In some embodiments, when the second warning judgment result corresponding to any target battery pack indicates a warning, the display interface also displays the second warning reason corresponding to any target battery pack and the corresponding second operation and maintenance suggestion. This can quickly help the staff to identify the warning reason of any target battery pack and give operation and maintenance suggestions, so as to timely inspect and repair the target battery pack and improve the safety and work efficiency of the energy storage power station.

[0074] For example, when the second warning result includes low charging efficiency of the battery pack, the corresponding second operation and maintenance suggestions include: promptly using a multimeter to measure the battery cell voltage for comparison and inspection, and performing operations such as replacing or recharging the battery cells according to actual conditions.

[0075] For example, when the second warning result includes poor heat dissipation performance and poor thermal stability of the battery pack, the corresponding second operation and maintenance suggestions include: tighten the positive and negative terminals of the battery; check the battery temperature probe and temperature measurement circuit; continuously monitor the battery temperature to observe whether the temperature deviates further from the normal value; fill in the defect record, fill in the maintenance plan and suggest checking the working status of the air conditioner to see if there is any abnormal sound or vibration, and whether the indoor temperature and humidity are within the set range.

[0076] In some embodiments, when the fourth identifier corresponding to any target battery cell in the display interface is selected, the first warning reason corresponding to any target battery cell and the corresponding first operation and maintenance suggestion are displayed in the display interface. In this way, it can quickly help the staff to identify the warning reason of any target battery cell and give operation and maintenance suggestions, so as to timely inspect and repair the target battery cell and improve the safety and work efficiency of the energy storage power station.

[0077] In this embodiment, the first warning judgment result corresponding to each battery cell in the energy storage power station, the second warning judgment result corresponding to each battery pack, the third warning judgment result corresponding to each battery cluster, and the fourth warning judgment result corresponding to each battery compartment are determined, and then the target battery compartment, target battery cluster, target battery pack, and target battery cell to be warned are determined according to the first warning judgment result, the second warning judgment result, the third warning judgment result, and the fourth warning judgment result. Finally, according to the target battery compartment, the target battery cluster, the target battery pack, and the target battery cell, a warning display is performed in the display interface. Therefore, by setting intelligent warnings in multiple dimensions of battery cell level, battery pack, battery cluster, and battery compartment, the warning accuracy can be improved, the potential risk of failure can be reduced, and the safety and stability of the energy storage power station can be improved, so that the failure can be solved in time and the operation efficiency of the power station can be fully guaranteed.

[0078] Figure 3 This is a flow chart of an energy storage power station early warning method provided in an embodiment of the present application. Figure 3 As shown, the energy storage power station early warning method may include the following steps:

[0079] Step 301, determining a first temperature distribution and a voltage distribution corresponding to all battery cells in an energy storage power station, a second temperature distribution corresponding to all transformers, and a third temperature distribution corresponding to all converters.

[0080] Step 302: Determine the fifth warning judgment result, the fifth warning reason and the corresponding fifth operation and maintenance suggestion corresponding to the energy storage power station according to the first temperature distribution, the second temperature distribution, the third temperature distribution and the voltage distribution.

[0081] In some embodiments, when the temperatures of most of the battery cells exceed the first temperature threshold in the first temperature distribution, the fifth warning result is determined to be a warning, and the fifth warning reason includes a battery cell temperature warning.

[0082] In some embodiments, when the temperatures of most transformers in the second temperature distribution exceed the second temperature threshold, the fifth warning result is determined to be a warning, and the fifth warning reason includes a transformer temperature warning.

[0083] In some embodiments, when the temperatures of most converters in the third temperature distribution exceed the third temperature threshold, the fifth warning result is determined to be a warning, and the fifth warning reason includes a converter temperature warning.

[0086] In the embodiment of the present disclosure, the first temperature distribution, the second temperature distribution, the third temperature distribution, and the voltage distribution can be displayed in the display interface, so that the overall situation of the energy storage power station can be intuitively displayed.

[0087] In the disclosed embodiment, when the fifth warning judgment result indicates a warning, the fifth warning cause and the fifth operation and maintenance suggestion are displayed, thereby quickly helping the staff to identify the warning cause of the energy storage power station and give operation and maintenance suggestions, so as to timely inspect and repair the energy storage power station and improve the safety and work efficiency of the energy storage power station.

[0088] In the embodiment of the present disclosure, the first identifier corresponding to each battery compartment can also be displayed in the display interface, so that the battery compartments included in the energy storage power station can be intuitively displayed. After the target battery compartment is determined, the first identifier corresponding to the target battery compartment can be directly displayed in the display interface in a different style from the first identifier corresponding to the non-target battery compartment, so that the target battery compartment for warning can be quickly determined.

[0089] In this embodiment, it is also possible to give early warning of failures in the energy storage power station from the overall dimension of the energy storage power station, thereby further improving the accuracy of early warnings, reducing potential failure risks, and further improving the safety and stability of the energy storage power station, thereby being able to resolve failures in a timely manner and fully ensuring the operating efficiency of the power station.
