[0047] The following will clearly illustrate the spirit of the present disclosure with the accompanying drawings and detailed descriptions. After understanding the embodiments of the present disclosure, any person having ordinary knowledge in the technical field can make changes and modifications based on the techniques taught by the present disclosure without departing from the spirit and scope of the present disclosure.

[0048] Please refer to Figure 1 , Figure 1 1 is a block diagram of an energy storage cabinet management system 100 according to some embodiments of the present invention. In some embodiments, the energy storage cabinet management system 100 includes a plurality of detection circuits TA1 to TAn, TB1 to TBn and a management device 110. The management device 110 includes a processor 112.

[0049] In some embodiments, a plurality of detection circuits TA1 to TAn, TB1 to TBn are located in the energy storage cabinet 900. The plurality of detection circuits TA1 to TAn, TB1 to TBn are coupled to the management device 110. In some embodiments, the energy storage cabinet 900 is coupled to the management device 110. It should be noted that more energy storage cabinets and detection circuits located in the energy storage cabinets can be coupled to the management device 110.

[0050] Please refer to Figure 2 . Figure 2 is a block diagram of an energy storage cabinet 900 according to some embodiments of the present disclosure. Figure 2 As shown, the energy storage cabinet 900 includes a plurality of battery cabinets 910A to 910D.

[0051] The battery cabinets 910A to 910D each include a plurality of module circuits. Taking the battery cabinet 910A as an example, the battery cabinet 910A includes a plurality of module circuits 912A1 to 912An. The plurality of module circuits 912A1 to 912An each include a plurality of battery cells. Taking the module circuit 912A1 as an example, the module circuit 912A1 includes a plurality of battery cells H1 to Hn.

[0052] like Figure 2 The number of battery cabinets, module circuits, and cells shown are for illustration purposes only. In one embodiment, one energy storage cabinet includes 4 battery cabinets, one battery cabinet includes 16 module circuits, and one module circuit includes 20 cells. However, the implementation of this case is not limited to the above.

[0053] like Figure 1 The energy storage cabinet management system 100 shown in FIG. Figure 2 The operation method of the energy storage cabinet 900 will be referred to in the following paragraphs. Figure 3 Provide explanation.

[0054] Please refer to Figure 3 . Figure 3 is a flow chart of a management method 300 according to some embodiments of the present disclosure. The management method 300 may be Figure 1 The energy storage cabinet management system 100 shown executes the management method 300 including steps S310 to S370.

[0055] In step S310, a plurality of voltage values ​​and a plurality of temperature values ​​of each of a plurality of battery cabinets within a unit time are obtained. In some embodiments, step S310 is performed by Figure 1 The processor 112 and the detection circuits TA1 to TAn, TB1 to TBn operate.

[0056] In some embodiments, the unit time may be every minute, every five minutes, every half hour, every hour, or a unit time of any default length.

[0057] Please refer back to Figure 1 , the following will be obtained Figure 2 The battery cabinet 910A in FIG. 1 is used as an example to illustrate the multiple voltage values ​​and multiple temperature values ​​of the battery cabinet 910A in a unit time. Assume that a part of the multiple detection circuits TA1 to TAn and a part of the multiple detection circuits TB1 to TBn are located at Figure 2In some embodiments, some of the detection circuits TA1 to TAn in the battery cabinet 910A are used to obtain voltage values, and some of the detection circuits TB1 to TBn in the battery cabinet 910A are used to obtain temperature values.

[0058] In some embodiments, the detection circuits TA1 to TAn transmit the obtained voltage values ​​to the processor 112. The detection circuits TB1 to TBn transmit the obtained temperature values ​​to the processor 112.

[0059] In one embodiment, each battery cabinet includes four of the plurality of detection circuits TB1 to TBn, that is, four temperature values ​​are obtained for each battery cabinet in one unit time.

[0060] In one embodiment, each battery cell corresponds to one of the detection circuits TA1 to TAn. Taking the module circuit 912A1 of the battery cabinet 910A as an example, if the module circuit 912A1 includes 20 battery cells, then within a unit time, 20 voltage values ​​are obtained for the module circuit 912A1.

[0061] In step S330, multiple battery cabinet index values ​​of multiple battery cabinets are calculated according to multiple voltage values ​​and multiple temperature values. In some embodiments, step S330 is performed by Figure 1 The processor 112 in the operation.

[0062] Please refer to Figure 4 . Figure 4 FIG. 1 is a flow chart of step S330 in the management method 300 according to some embodiments of the present disclosure. Figure 4 As shown, step S330 includes steps S332 to S336. Figure 2 The battery cabinet index value ECI1 of the battery cabinet 910A in FIG. 1 is used as an example for explanation.

[0063] In step S332, multiple module voltage pointer values ​​of multiple module circuits are calculated. The following description is made by taking the module circuit 912A1 in the battery cabinet 910A as an example.

[0064] Assume that the module circuit 912A1 includes n battery cells H1 to Hn. Figure 1 The processor 112 in the module 912A1 obtains the n cell voltage values ​​of the n cells H1 to Hn in a unit time through the detection circuits TA1 to TAn, obtains the highest cell voltage value Vmax and the lowest cell voltage value Vin among the n cell voltage values, and calculates the average cell voltage value of the n cell voltage values. Next, the processor 112 calculates the maximum cell voltage value Vmax, the minimum cell voltage value Vin, and the average cell voltage value Calculate the voltage uniformity VU%.

[0065] In some embodiments, the processor 112 calculates the voltage uniformity VU % according to the following formula (1).

[0066] (Formula 1)

[0067] In some embodiments, the processor 112 calculates the module voltage pointer value ViciA1 of the module circuit 912A1 according to the voltage value uniformity VU%. In some embodiments, the processor 112 calculates the module voltage pointer value ViciA1 according to the following formula (2).

[0068] (Formula 2)

[0069] In some embodiments, the threshold value in the above formula (2) is a preset parameter of 0.1. However, the implementation of the present invention is not limited thereto.

[0070] In this way, the processor 112 can calculate the module voltage pointer value ViciA1 of the module circuit 912A1 within a unit time. Similarly, the processor 112 can calculate the module voltage pointer values ​​ViciA2 to ViciAn of the remaining module circuits in the same manner.

[0071] Please continue to refer to Figure 4 In step S334, the temperature pointer value of the battery cabinet is calculated. The following also takes the battery cabinet 910A as an example. Assume that the processor 112 obtains multiple battery cabinet temperature values ​​of the battery cabinet 910A through the detection circuits TB1 to TBn within a unit time. The processor 112 then obtains the highest battery cabinet temperature value Tmax and the lowest battery cabinet temperature value Tmin among the multiple battery cabinet temperature values, and calculates the average battery cabinet temperature value of the multiple battery cabinet temperature values. Next, the processor 112 generates a battery cabinet temperature value Tmax, a battery cabinet temperature value Tmax, a battery cabinet temperature value Tin, and an average battery cabinet temperature value Tmax. Calculate the temperature uniformity TU%.

[0072] In some embodiments, the processor 112 calculates the temperature uniformity TU% according to the following formula (3).

[0073] (Formula 3)

[0074] In some embodiments, the processor 112 calculates the temperature index value TiciA of the battery cabinet 910A according to the temperature uniformity TU%. In some embodiments, the processor 112 calculates the temperature index value TiciA according to the following formula (4).

[0075] (Formula 4)

[0076] In some embodiments, the threshold value in the above formula (4) is a preset parameter of 0.1. However, the implementation of the present invention is not limited thereto.

[0077] In this way, the processor 112 can calculate the temperature index value TiciA of the battery cabinet 910A per unit time.

[0078] Please continue to refer to Figure 4 In step S336, a battery cabinet index value of the battery cabinet is obtained according to a plurality of module voltage pointer values ​​and temperature pointer values.

[0079] Take the battery cabinet 910A as an example. In step S332, the processor 112 calculates the multiple module voltage pointer values ​​ViciA1 to ViciAn of the battery cabinet 910A. In step S334, the processor 112 calculates the temperature pointer value TiciA of the battery cabinet 910A. In step S336, the processor calculates the battery cabinet index value ECIA of the battery cabinet 910A based on the multiple module voltage pointer values ​​ViciA1 to ViciAn and the temperature pointer value TiciA.

[0080] In some embodiments, the processor 112 calculates the battery cabinet index value ECIA according to the following formula (5).

[0081] Formula (5) The above ICI includes module voltage pointer values ​​ViciA1 to ViciAn and a temperature pointer value TiciA.

[0082] Similarly, the processor 112 can calculate the battery cabinet index values ​​ECIB, ECIC and ECID of the remaining battery cabinets 910B to 910D in the same manner.

[0083] Please refer back Figure 3 In step S350, the energy storage cabinet index value is obtained according to the multiple battery cabinet index values. In some embodiments, step S350 is performed by Figure 1 The processor 112 in the operation.

[0084] In some embodiments, in step S350 , the processor 112 uses the lowest battery cabinet index value among the plurality of battery cabinet index values ​​as the energy storage cabinet index value ESSCI.

[0085] For example, assuming that among the multiple battery cabinet index values ​​ECIA to ECID included in the energy storage cabinet 900, the battery cabinet index value ECIA is the lowest, the processor 112 uses the battery cabinet index value ECIA as the energy storage cabinet index value ESSCI of the energy storage cabinet 900 per unit time.

[0086] In step S370, it is determined whether the energy storage cabinet is abnormal according to the energy storage cabinet indicator value. In some embodiments, step S370 is performed by Figure 1 The processor 112 in the operation.

[0087] Please refer to Figure 5 . Figure 5 is a schematic diagram of a management screen 500 according to some embodiments of the present invention. Figure 5 In some embodiments, the management device 110 further includes a display 114 for displaying a management screen 500. As shown in the management screen 500, the horizontal axis is time, and the vertical axis is the energy storage cabinet index value ESSCI. In some embodiments, when the energy storage cabinet pointer value ESSCI is lower than the energy storage cabinet index threshold value TH in a certain unit time, the processor 112 determines that the energy storage cabinet 900 is abnormal.

[0088] For example, as shown in the management screen 500 , at time point 111 , the energy storage cabinet indicator value ESSCI is lower than the energy storage cabinet indicator threshold TH, which means that the energy storage cabinet 900 is abnormal at time point 111 .

[0089] In some embodiments, the energy storage cabinet indicator threshold TH is obtained by learning and training according to a management cycle by the processor 112. If it is found that the energy storage cabinet indicator threshold TH is inaccurate, retraining can be performed and the length of the management cycle can be reset.

[0090] Please refer to Figure 6 . Figure 6 is a schematic diagram of a management screen 600 according to some embodiments of the present disclosure. In some embodiments, Figure 1 The display 114 is further used for the user to select Figure 5 At time point 111 in the management screen 500, the management screen 600 is displayed. The management screen 600 displays the detailed information of the lowest battery cabinet pointer value ECI.

[0091] For example, if the lowest battery cabinet index value in the energy storage cabinet 900 is the battery cabinet index value ECIA of the battery cabinet 910A, then the detailed information of the battery cabinet 910A is displayed in the management screen 600 . Figure 6 The title 910A-111 shown in the figure represents the detailed data of the battery cabinet 910A at the time point 111.

[0092] like Figure 6 As shown in FIG. 6 , in the management screen 600 , multiple module data and temperature data of the battery cabinet 910A are displayed, which correspond to multiple module voltage pointer values ​​ViciA1 to ViciAn and temperature pointer value TiciA of the battery cabinet 910A respectively.

[0093] in accordance with Figure 6 From the content, it can be known that the module voltage pointer value ViciA1 of the module circuit 912A1 has the greatest impact on the battery cabinet index value ECIA.

[0094] Please refer to Figure 7 . Figure 7 is a schematic diagram of a management screen 700 according to some embodiments of the present disclosure. In some embodiments, Figure 1 The display 114 is further used for the user to select Figure 6 When the module voltage pointer value in the management screen 600 is ViciA1, the management screen 700 is displayed.

[0095] The management screen 700 displays the cell voltage values ​​of all cells H1 to Hn in the module circuit 912A1. It can be seen from the management screen 700 that the cell voltage values ​​of cells H1 and H2 vary greatly from the cell voltage values ​​of the other cells. Therefore, it can be determined that the abnormality occurs in the cells H1 and H2 of the module circuit 912A1. In this way, it is possible to quickly and effectively find out where the energy storage cabinet 900 has an abnormality.

[0096] In some embodiments, the management device 110 may be established by a computer, a server or a processing center. In some embodiments, the processor 112 may be implemented by a processing unit, a central processing unit or a computing unit.

[0097] In some embodiments, the management device 110 is not limited to including Figure 1 In addition to the components shown in the figure, the management device 110 may further include other components required for operation and application. For example, the management device 110 may further include an output interface (for example, a display panel for displaying information), an input interface (for example, a touch panel, a keyboard, a microphone, a scanner or a flash memory reader) and a communication circuit (for example, a WiFi communication model, a Bluetooth communication model, a wireless telecommunication network communication model, etc.).

[0098] In some embodiments, Figure 1 The management device 110 in the embodiment further includes a memory (not shown), which may be a flash memory, a HDD, an SSD (solid state drive), a DRAM (static random access memory) or an SRAM (dynamic random access memory). In some embodiments, the memory may be a non-transient computer storage medium storing at least one instruction including the management method 300. The at least one instruction may be accessed and executed by the processor 112.

[0099] In summary, the management method and energy storage cabinet management system of the disclosed embodiment can collect multiple voltage values ​​and temperature values ​​in the energy storage cabinet, and calculate the module voltage pointer value and the temperature pointer value according to the obtained voltage values ​​and temperature values, and then calculate the battery cabinet index value and the energy storage cabinet value, and then determine whether the energy storage cabinet is abnormal according to the above index values, and can quickly and efficiently obtain the abnormality in the energy storage cabinet.

[0100] In addition, it should be noted that, in the steps of the management method 300, there is no particular order requirement unless otherwise specified. In addition, these steps can also be executed simultaneously, or their running time can at least partially overlap.
