[0064] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0066] In conjunction with the accompanying drawings, the energy storage system fan inspection method, energy storage system fan inspection device, electronic device and readable storage medium provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0067] The energy storage system fan inspection method may be applied to the energy storage system, and may be specifically executed by hardware or software in the energy storage system.

[0068] The energy storage system fan inspection method provided in the embodiment of the present application, the execution subject of the energy storage system fan inspection method can be the energy storage system or a functional module or functional entity in the energy storage system that can implement the energy storage system fan inspection method, or can be a server connected to the energy storage system for communication, or can also be a user terminal connected to the energy storage system for communication, including but not limited to the user's mobile phone, PC and desktop computer; the energy storage system fan inspection method provided in the embodiment of the present application is described below by taking the energy storage system as the execution subject as an example.

[0069] Combine the following Figure 1-Figure 5 The energy storage system fan inspection method of the present application is described.

[0070] It should be noted that the energy storage system fan inspection method can be applied to the thermal management scenario of the energy storage system based on air conditioning thermal management, where the energy storage system includes but is not limited to battery energy storage system, photovoltaic energy storage system and other energy storage systems.

[0071] The energy storage system may include a battery pack, a fire protection system, a container system and a fan system, wherein the fan system includes at least two of a PACK fan, a relay fan and an exhaust fan.

[0072] The fan system, fire protection system and battery pack are arranged in the container system, and the exhaust fan is arranged in the fire protection system.

[0073] Among them, the PACK fan is the fan that comes with the battery pack in the container system; the exhaust fan is the fan used by the container system in the exhaust process, which can be set on the side wall of the container system; the relay fan is a fan installed in the middle of the container system, which is used to ensure that the air conditioning airflow on both sides can be exchanged.

[0074] like Figure 1 As shown, the energy storage system fan inspection method includes: step 110, step 120 and step 130.

[0075] Step 110: determining the working state of the energy storage system based on the acquired first working parameter of the energy storage system;

[0076] In this step, the battery pack may be a storage battery pack or any other energy storage unit.

[0077] The first operating parameter is a real-time operating parameter of the battery pack, and is used to characterize the operating state of the battery pack.

[0078] The working state of the battery pack includes a normal state and an abnormal state, and the normal state further includes an operating state and a non-operating state.

[0079] The first operating parameter can be obtained through a battery management system, which is not limited in this application.

[0080] In some embodiments, step 110 may further include: determining the working state of the energy storage system based on the acquired first working parameter of the energy storage system within a settable time.

[0081] Step 120: When the energy storage system is in a non-operating state and the fan system is in a non-operating state, obtain a second operating parameter of the energy storage system; the second operating parameter includes at least two of a first sub-operating parameter of the fire protection system, a second sub-operating parameter of the container system, and a third sub-operating parameter of the fan system;

[0082] In this step, the second operating parameter is used to perform automatic inspection of the fan system.

[0083] The second operating parameter includes at least two of a first sub-operating parameter of the fire protection system, a second sub-operating parameter of the container system, and a third sub-operating parameter of the fan system.

[0084] Among them, the first sub-working parameter is used to determine whether the fire protection system fails.

[0085] The second sub-operating parameter is used to determine the temperature information of the container system, including but not limited to the ambient temperature difference of the container system and the single cell temperature difference of the container system.

[0086] The third sub-operating parameter is used to characterize the operating state of the fan system, and the third sub-operating parameter includes: at least one of the operating parameters corresponding to the PACK fan, the operating parameters corresponding to the relay fan, and the operating parameters corresponding to the exhaust fan.

[0087] After obtaining the second operating parameter, the second operating parameter may be stored in a local database or a cloud database so that it can be retrieved when needed later.

[0088] Step 130 : determining fault information of a target type of fan in the fan system based on the second operating parameter, wherein different types of fans correspond to different methods for determining fault information.

[0089] In this step, the target type of fan may be any one or more of a PACK fan, a relay fan and an exhaust fan.

[0090] The fault information of different types of fans can be determined based on the second working parameter, and the specific determination methods (inspection and protection strategies) are different. The determination methods of the fault information of different types of fans will be specifically described below and will not be repeated here.

[0091] The fault information includes at least one of a fault level and a fault type.

[0092] The fault level is used to characterize the fault degree of the fan system.

[0093] For example, the fault level may include multiple levels such as normal, general abnormality and severe abnormality. In actual application, it can be set based on actual conditions, and this application does not limit it.

[0094] Fault types include PACK fan fault, relay fan fault, and exhaust fan fault.

[0095] It can be understood that when the fault information includes the fault level and fault type, the fault information can be expressed as: PACK fan normal, PACK fan generally abnormal, PACK fan seriously abnormal, relay fan normal, relay fan generally abnormal, relay fan seriously abnormal, exhaust fan normal and exhaust fan seriously abnormal, etc.

[0096] like Figure 2 As shown, in the actual implementation process, the first operating parameter of the battery pack can be acquired through the battery management system, and the operating state of the battery pack can be determined based on the first operating parameter.

[0097] When it is determined that the battery pack is in a normal and operating state, the operating state of the battery pack is continuously monitored through the battery management system.

[0098] When it is determined that the battery pack is in a normal state and is not in an operating state, it is further determined whether the fan system is operating.

[0099] When the fan system is confirmed to be running, the battery management system continuously monitors the working status of the battery pack.

[0100] When it is determined that the fan system is not operating, the second operating parameter of the energy storage system is obtained to determine the fault information of the target type of fan in the fan system, so as to determine whether the fan system has a fault based on the fault information, thereby realizing automatic inspection of the fan system.

[0101] It should be noted that in the present application, different types of fans may have different corresponding second operating parameters, and the corresponding fault information determination methods may also be different. The present application will specifically describe the fault information determination methods of different types of fans in the following embodiments, which will not be elaborated here.

[0102] Continue to refer Figure 2 In some embodiments, step 130 may further include:

[0103] Determining the working state of the fire protection system based on the first sub-working parameter;

[0104] When the fire protection system is in a non-fault state and the energy storage system is more than a first time period from the last detection, determining a first temperature difference of the energy storage system within the first time period;

[0105] When the first temperature difference exceeds the first temperature threshold, a target inspection signal is sent, where the target inspection signal is used to detect the fan system;

[0106] In response to the target inspection signal, fault information of the fan system is determined based on the second operating parameter.

[0107] In this embodiment, the working state of the fire protection system includes a fault state or a non-fault state.

[0108] The first duration can be customized by the user, such as being set to 24 hours.

[0109] The first temperature threshold is used to determine whether the first temperature difference is abnormal. If the first temperature difference exceeds the first temperature threshold, it can be considered that the first temperature difference is abnormal.

[0110] The first temperature threshold is a preset temperature threshold. The value of the first temperature threshold can be set based on actual conditions and is not limited in this application.

[0111] The target patrol signal is used to detect a fan in the fan system that corresponds to the type of the target patrol signal.

[0112] The target inspection signal may include: a PACK fan inspection signal, a relay fan inspection signal, and an exhaust fan inspection signal.

[0113] In other embodiments, when the working state of the fire protection system is a non-fault state and the energy storage system has not been detected for more than a first time period since the last detection, the detection time period is continuously monitored until the first time period has passed since the last detection.

[0114] According to the energy storage system fan inspection method provided in the embodiment of the present application, by comparing the first temperature difference of the energy storage system within the target time period with the first temperature threshold when the fire protection system is not faulty, it is determined whether the first temperature difference is abnormal, and a fan inspection signal is sent in the case of abnormality. This can eliminate the influence of other factors on the fan inspection result, thereby improving the accuracy of the detection result.

[0115] Continue to refer Figure 2 In some embodiments, after determining the first temperature difference of the energy storage system within the first time period and before determining the fault information of the fan system based on the second operating parameter in response to the target inspection signal, the method may further include:

[0116] When the first temperature difference does not exceed the first temperature threshold and the energy storage system is more than a second time away from the last detection, a target inspection signal is sent;

[0117] Among them, the second duration is longer than the first duration.

[0118] In this embodiment, the second duration is longer than the first duration, and the second duration may be user-defined, such as setting the second duration to 72 hours or 48 hours, etc., which is not limited in this application.

[0119] During the actual execution process, when the first temperature difference does not exceed the first temperature threshold and the energy storage system is more than the second time period from the last detection, a target inspection signal is sent; then, in response to the target inspection signal, the fan corresponding to the target inspection signal is detected to determine the fault information of the fan system.

[0120] In other embodiments, when the first temperature difference does not exceed the first temperature threshold and the energy storage system is not more than a second time period from the last detection, the detection time is continuously monitored until the energy storage system is more than the second time period from the last detection.

[0121] According to the fan inspection method for the energy storage system provided in the embodiment of the present application, by directly sending a target inspection signal to perform fan inspection when the accumulated non-detection time is long, it is possible to implement periodic scheduled inspection of the fan system, facilitate daily maintenance of the fan system, thereby improving the safety of the energy storage system and solving the technical problem in the related art that it is impossible to effectively ensure the reliable and safe operation of the energy storage system.

[0122] Continue to refer Figure 2 In some embodiments, after step 130, the method may further include:

[0123] When it is determined that the fan system is in a normal state, the working state of the battery pack continues to be monitored through the battery management system;

[0124] When it is determined that the fan system is in a fault state, a warning message is output.

[0125] In this embodiment, the warning information is generated based on the fault information.

[0126] Warning information can be output in at least one of the following ways:

[0127] First, the output can be presented as text output.

[0128] In this embodiment, fault information and warning information can be output in the form of text to promptly notify operation and maintenance personnel to perform maintenance.

[0129] Second, the output can be in the form of voice output.

[0130] In this embodiment, the operation and maintenance personnel can be warned by voice that the current fan system has a fault.

[0131] Third, the output can be in the form of image output.

[0132] In this embodiment, the warning information may be displayed on the screen of the user terminal or the screen of the monitoring center to remind the operation and maintenance personnel to take relevant measures in a timely manner.

[0133] Fourthly, the output can be expressed as a signal light output.

[0134] In this embodiment, a signal light corresponding to the failed fan may flash to remind the operation and maintenance personnel that the fan has failed.

[0135] Of course, in other embodiments, the output may also be in other forms, which can be determined according to actual needs, and this application does not limit this.

[0136] In this embodiment, by outputting warning information, the operation and maintenance personnel can be reminded in time to select corresponding maintenance measures based on the fault situation, so as to prevent the firefighting from being unable to operate normally when a firefighting failure occurs, thereby preventing the expansion of safety accidents, effectively reducing safety hazards, and ensuring the reliable and safe operation of the energy storage system, thereby solving the technical problem that the related technology cannot effectively ensure the reliable and safe operation of the energy storage system.

[0137] Continue to refer Figure 2 In some embodiments, after step 130, the method may further include: determining the number of self-tests of the fan system.

[0138] Continue to refer Figure 2 In some embodiments, after step 130, the method may further include: recording location information.

[0139] In this embodiment, the location information is used to characterize the fault location where the fault occurs.

[0140] In the present application, the fault information of the fan system is determined based on at least two of the second working parameters including the first sub-working parameters of the fire protection system, the second sub-working parameters of the container system and the third sub-working parameters of the fan system. The detection result has high accuracy and comprehensive detection dimensions, which can improve the accuracy of the detection result; and no manual operation is required, with a high degree of automation, thereby improving the inspection effect.

[0141] In addition, by selecting the corresponding fault determination method based on the type of fan, the detection scheme can be flexibly adjusted based on different fans to achieve the best detection effect, which can further improve the accuracy of the fault detection results. It is highly flexible and suitable for a wide range of application scenarios.

[0142] According to the energy storage system fan inspection method provided in the embodiment of the present application, different fault information determination methods are adopted to determine the fault information of the target type of fans in the fan system based on the second working parameter. This method has high detection efficiency and more accurate detection results. While effectively maintaining the normal operation of the energy storage system, it can significantly reduce manpower and time costs, thereby solving the technical problems of poor inspection effect and high manpower cost in related technologies.

[0143] The following describes the methods for determining the faults of different types of fans from three implementation perspectives.

[0144] 1. PACK fan inspection

[0145] like Figure 3 As shown, in some embodiments, when the target inspection signal is a PACK fan inspection signal; based on the second working parameter, determining the fault information of the target type of fan in the fan system may include:

[0146] Acquire the number of first branches of the abnormal PACK fan based on the third sub-operating parameter;

[0147] When the first branch quantity is greater than the first target value, fault information of the PACK fan is determined based on the first branch quantity and the second target value.

[0148] In this embodiment, the first target value is a preset value, and the first target value is a smaller value, which can be customized based on the user, such as setting the first target value to 0 or 1, etc., which is not limited in this application.

[0149] The second target value is greater than the first target value. The second target value can be customized based on the user, such as being set to 3 or 5, etc., which is not limited in this application.

[0150] In this embodiment, when the number of the first branches is greater than the first target value, the fault information of the PACK fan is determined based on the magnitude relationship between the number of the first branches and the second target value.

[0151] In some embodiments, obtaining the number of first branches of abnormal PACK fans based on the third sub-working parameter may include: inspecting the PACK fans of each battery cluster in sequence according to the target order, and obtaining the number of first branches of abnormal PACK fans based on the third sub-working parameter.

[0152] In this embodiment, by setting the target order to check the PACK fans of multiple battery clusters in sequence, batch inspection according to the battery cluster level is achieved, which has a high detection efficiency. Figure 3In some embodiments, when the working state of the fire protection system is a non-fault state and the PACK fan is not more than a first time length from the last detection, the detection time length is continuously monitored until it exceeds the first time length from the last detection.

[0153] In some embodiments, when the number of the first branches is not greater than the first target value, the system returns to continue monitoring the working status of the fire protection system.

[0154] In some embodiments, determining the fault information of the PACK fan based on the first branch quantity and the second target value may include:

[0155] When the number of the first branches is greater than the second target value, determining that the fault information of the PACK fan is a serious fault;

[0156] When the number of the first branches is not greater than the second target value, determining the ambient temperature difference of the container system based on the second sub-operating parameter;

[0157] When the ambient temperature difference exceeds a second temperature threshold, determining a cell temperature difference of the container system based on a second sub-operating parameter;

[0158] When the cell temperature difference exceeds the third temperature threshold, it is determined that the fault information of the PACK fan is a serious fault.

[0159] In this embodiment, the second temperature threshold and the third temperature threshold are both preset values, and their values ​​can be customized based on the user, which is not limited in this application.

[0160] The following takes the first target value as 0 as an example to specifically illustrate this embodiment.

[0161] like Figure 3 As shown, the energy storage system first determines the working state of the fire protection system based on the first sub-working parameter; when the working state of the fire protection system is non-faulty and the energy storage system is more than 24 hours away from the last detection, the first temperature difference of the energy storage system within the first time period is further determined based on the first sub-working parameter; when the first temperature difference exceeds the first temperature threshold, a PACK fan inspection signal is sent.

[0162] After receiving the PACK fan inspection signal, the PACK fan is inspected in response to the PACK fan inspection signal, and then the first branch number of the abnormal PACK fan is obtained in response to the PACK fan inspection signal; when the first branch number is greater than 0, whether the first branch number is greater than the second target value is continued to be determined.

[0163] When it is determined that the number of first branches is not greater than the second target value, the ambient temperature difference of the container system is determined based on the second sub-working parameter; when the ambient temperature difference exceeds the second temperature threshold, the single cell temperature difference of the container system is determined based on the second sub-working parameter; when the single cell temperature difference exceeds the third temperature threshold, the fault information of the PACK fan is determined to be a serious fault.

[0164] Continue to refer Figure 3 In other embodiments, when the number of first branches is not greater than the second target value and the ambient temperature difference does not exceed the second temperature threshold, the fault information of the PACK fan is determined to be a general fault.

[0165] Continue to refer Figure 3 In other embodiments, when the ambient temperature difference exceeds the second temperature threshold and the cell temperature difference does not exceed the third temperature threshold, the fault information of the PACK fan is determined to be a general fault.

[0166] According to the energy storage system fan inspection method provided in the embodiment of the present application, the fault level of the PACK fan is determined based on parameters such as the working status of the fire protection system, the detection time, the first temperature difference of the energy storage system, the number of the first branch of the PACK fan failure, the ambient temperature difference of the container system, and the single cell temperature of the container system, thereby significantly improving the accuracy and precision of the judgment result, thereby avoiding the increase in system temperature difference due to the failure to timely discover and replace the PACK fan abnormality, resulting in uneven branch flow, reduced system charge and discharge capacity, and thus exacerbating the inconsistency of the system battery cells.

[0167] 2. Relay fan inspection

[0168] like Figure 4 As shown, in some embodiments, when the target inspection signal is a relay fan inspection signal; based on the second working parameter, determining the fault information of the fan of the target type in the fan system may include:

[0174] Continue to refer Figure 4 In other embodiments, when the working state of the fire protection system is non-faulty and the relay fan is no more than a first time length from the last detection, the detection time is continuously monitored until the first time length from the last detection is exceeded, and then subsequent steps are continued.

[0176] Based on the second sub-operating parameter, determining an ambient temperature difference of the container system;

[0178] When the cell temperature difference exceeds the third temperature threshold, it is determined that the fault information of the relay fan is a serious fault.

[0179] In this embodiment, the second temperature threshold and the third temperature threshold are both preset values, and their values ​​can be customized based on the user, which is not limited in this application.

[0180] For example, in actual implementation, Figure 4 As shown, the energy storage system first determines the working status of the fire protection system based on the first sub-working parameter; when the working status of the fire protection system is non-faulty and the relay fan is more than 24 hours away from the last detection, the first temperature difference of the energy storage system within the first time period is determined; when the first temperature difference exceeds the first temperature threshold, the relay fan inspection signal is sent.

[0182] When the ambient temperature difference exceeds the second temperature threshold, the cell temperature difference of the container system is determined based on the second sub-operating parameter; when the cell temperature difference exceeds the third temperature threshold, the fault information of the relay fan is determined to be a serious fault.

[0184] Continue to refer Figure 4 In other embodiments, when the ambient temperature difference exceeds the second temperature threshold and the cell temperature difference does not exceed the third temperature threshold, the fault information of the relay fan is determined to be a general fault.

[0185] According to the fan inspection method of the energy storage system provided in the embodiment of the present application, the fault level of the relay fan is determined based on parameters such as the working status of the fire protection system, the detection time, the first temperature difference of the energy storage system, the number of second branches with relay fan failures, the ambient temperature difference of the container system, and the single cell temperature of the container system, thereby significantly improving the accuracy and precision of the judgment result, thereby avoiding problems such as an increase in the system temperature difference due to the failure to timely discover and replace the abnormality of the relay fan, resulting in uneven current in the branches, a reduction in the system's chargeable and dischargeable capacity, and thus exacerbating the inconsistency of the system's battery cells.

[0189] When the number of the third branches is greater than the fourth target value, it is determined that the fault information of the exhaust fan is a serious fault.

[0190] In this embodiment, the fourth target value is a preset value, the fourth target value is a smaller value, and the fourth target value may be the same as the first target value, such as being set to 0, which is not limited in this application.

[0191] Taking the fourth target value of 0 as an example, in the actual execution process, if Figure 5 As shown, the energy storage system first determines the working state of the fire protection system based on the first sub-working parameter; when the working state of the fire protection system is non-faulty and the exhaust fan is more than 24 hours away from the last detection, the first temperature difference of the energy storage system within the first time period is determined based on the first sub-working parameter; when the first temperature difference exceeds the first temperature threshold, the exhaust fan inspection signal is sent.

[0192] After receiving the exhaust fan inspection signal, in response to the exhaust fan inspection signal, the number of the third branches of the abnormal exhaust fan is obtained; when the number of the third branches is greater than 0, it is determined that the fault information of the exhaust fan is a serious fault.

[0193] Continue to refer Figure 5 In other embodiments, when the number of the third branches is not greater than the fourth target value, the process returns to continue monitoring the working status of the fire protection system.

[0194] Continue to refer Figure 5 In other embodiments, when the working state of the fire protection system is non-faulty and the exhaust fan is not more than a first time period from the last detection, the detection time is continuously monitored until it exceeds the first time period from the last detection.

[0195] Continue to refer Figure 5 In other embodiments, when the first temperature difference exceeds the first temperature threshold, it is determined whether the exhaust fan has been detected for more than a second period of time since the last detection.

[0196] When it is determined that the second time period has been exceeded, an exhaust fan inspection signal is sent.

[0197] When it is determined that the second time period has not been exceeded, the detection time period is continuously monitored until the time period from the last detection exceeds the second time period.
