[0114] Referring to FIG. 7, steps S710 through S722 are shown as being performed prior to step S730, but are not limited thereto. For example, steps S710 through S722 may be performed after steps S730 and S740, or simultaneously with steps S730 and S740.

[0115] FIG. 8 is a flowchart illustrating an example of a battery container inspection method according to one embodiment of the present disclosure. A computing device (500) may determine one of at least one battery rack included in the battery container as a target battery rack. The computing device (500) is connected to a second battery management device (610), and the second battery management device (610) may be connected to a first battery management device (710) included in the target battery rack.

[0116] In one embodiment, the computing device (500) may request information about a target battery rack from the second battery management device (610) (S810).

[0118] Although not illustrated in FIG. 8, the computing device (500) can determine whether the first battery management device (710) is normal, similar to the second battery management device (610) of FIG. 7. Specifically, the computing device (500) can request information about the first battery management device (710) included in the target battery rack from the second battery management device (610). The second battery management device (610) can request information about the first battery management device (710) included in the target battery rack from the first battery management device (710). The first battery management device (710) can read information about the first battery management device (710) from the memory of the first battery management device (710). In response to the request, the second battery management device (610) can receive information about the first battery management device (710) included in the target battery rack from the first battery management device (710). The computing device (500) may receive information about the first battery management device (710) included in the target battery rack from the second battery management device (610) in response to a request. The information about the first battery management device (710) may include information about firmware that is pre-stored in the first battery management device (710).

[0119] In one embodiment, the computing device (500) can determine whether the first battery management device (710) included in the target battery rack is normal based on information regarding the first battery management device (710) included in the target battery rack. The information regarding the first battery management device (710) of the target battery rack may include information regarding the target firmware, which is the firmware included in the first battery management device (710) of the target battery rack. Specifically, the computing device (500) may obtain information regarding the first battery management device included in a predetermined reference battery rack. For example, the information regarding the first battery management device of the reference battery rack may include information regarding the reference firmware, which is the firmware included in the first battery management device of the reference battery rack.

[0120] In one embodiment, the computing device (500) can compare information about the target firmware with information about the reference firmware. For example, the computing device (500) can determine whether the version information of the target firmware corresponds to the version information of the reference firmware. In response to the determination that the version information of the target firmware corresponds to the version information of the reference firmware, the computing device (500) can determine that the first battery management device (710) included in the target battery rack is normal. In this case, a subsequent step (e.g., step S810) may be performed.

[0121] On the other hand, the computing device (500) may determine that the first battery management device (710) included in the target battery rack is abnormal in response to the determination that the version information of the target firmware does not correspond to the version information of the reference firmware. In this case, the computing device (500) may update the firmware included in the first battery management device (710) of the target battery rack. As another example, the computing device (500) may output information indicating that the firmware included in the first battery management device (710) of the target battery rack is abnormal.

[0122] FIG. 9 is a flowchart illustrating an example of a battery container inspection method according to one embodiment of the present disclosure. After step S740 of FIG. 7 or after step S840 of FIG. 8, a processor (e.g., a processor of the second battery management device (610) and / or a processor of the computing device (500)) may compare information about a target battery rack with information about a predetermined reference battery rack. The information about the target battery rack may include identification information of the target battery rack, and the information about the reference battery rack may include identification information of the reference battery rack.

[0123] Specifically, the processor can determine whether the identification information of the target battery rack corresponds to the identification information of the reference battery rack (S910). For example, the processor can determine whether the identification information of the target battery rack and the identification information of the reference battery rack are substantially identical. In response to the determination that the identification information of the target battery rack does not correspond to the identification information of the reference battery container, the processor can determine that the battery container is abnormal (S912). In response to the determination that the identification information of the target battery rack corresponds to the identification information of the reference battery container, the processor can determine whether all battery racks included in the battery container have been compared with the reference battery rack (S920).

[0124] In one embodiment, the processor may output information indicating the abnormality of the battery container in response to the determination that the battery container is abnormal. For example, in response to the determination that the battery container is abnormal, the processor may output location information of a target battery rack that is determined not to correspond to the identification information of the reference battery container. Additionally, the processor may output information indicating that the battery rack corresponding to the location information is abnormal. Here, the location information of the target battery rack may indicate the location of the target battery rack within the battery container. The location information of the target battery rack may be included in the information regarding the target battery rack. As a result, a user of the energy storage system can identify the location of the target battery rack that is determined not to correspond to the identification information of the reference battery container.

[0125] In one embodiment, the processor may stop operations associated with the battery container in response to determining that the battery container is abnormal. For example, the processor may disconnect the electrical connection of the battery container using a relay or the like included in the battery container. As another example, the processor may perform an inspection of the entire energy storage system including the battery container. The processor may stop the inspection of the energy storage system in response to determining that the battery container is abnormal.

[0126] In one embodiment, the processor may determine whether all battery racks included in the battery container have been compared with the reference battery rack in response to the determination that the identification information of the target battery rack corresponds to the identification information of the reference battery container (S920). Specifically, the processor may receive identification information for each of at least one battery rack as information regarding the target battery rack, and determine whether the identification information for each of at least one battery rack corresponds to the identification information of the reference battery rack. The processor may determine whether the determination of whether the identification information corresponds to the reference battery rack has been performed on all at least one battery rack included in the battery container. In response to the determination that all battery racks included in the battery container have been compared with the reference battery rack, the processor may determine that the battery container is normal (S922).

[0127] On the other hand, the processor may change the target battery rack in response to the determination that all battery racks included in the battery container have not been compared with the reference battery rack (S924). For example, prior to step S920, one of at least one battery rack included in the battery container may be determined as the target battery rack. In response to the determination that all battery racks included in the battery container have not been compared with the reference battery rack, the processor may identify the battery rack(s) among at least one battery rack included in the battery container that have not been compared with the reference battery rack. The processor may determine one of the identified battery rack(s) as the target battery rack instead of the previously determined target battery rack.

[0128] Subsequently, the processor may perform an inspection on the modified target battery rack. For example, step S710 or step S810 may be initiated for the modified target battery rack. That is, the processor may request information regarding the first battery management device included in the modified target battery rack, or request information regarding the target battery rack, and then perform the subsequent steps.

[0129] In one embodiment, the processor may determine whether the battery container is normal based on a determination result and a comparison result for the first battery management device. For example, the processor may determine that the identification information for each of at least one battery rack corresponds to the identification information of a reference battery rack, and determine that the battery container is normal in response to the first battery management device determining that it is normal. Additionally, the processor may determine that the battery container is abnormal in response to the first battery management device determining that it is abnormal.

[0130] FIG. 10 is a drawing for illustrating a battery container inspection method according to one embodiment of the present disclosure. An energy storage system (600) may include a first battery container (1010) including at least one first battery rack (1012) and a second battery container (1020) including at least one second battery rack (1022). The energy storage system (600) may include a second battery management device (610) connected to a first battery management device included in at least one battery rack (1012, 1022).

[0131] In one embodiment, information regarding a reference battery rack may be predetermined based on information regarding a battery container (1010, 1020). For example, the information regarding a reference battery rack for a first battery container (1010) and the information regarding a reference battery rack for a second battery container (1020) may be different. For example, for a first battery container (1010), the identification information of the reference battery rack may include information corresponding to the first identification information of the battery rack. For a second battery container (1020), the identification information of the reference battery rack may include information corresponding to the second identification information of the battery rack.

[0132] In one embodiment, information regarding a reference battery rack (e.g., identification information of the reference battery rack) may be predetermined to be different depending on the location inside the battery container (1010, 1020). However, in FIG. 10, information regarding a reference battery rack for the first battery container (1010) may be predetermined to be the same even if the location inside the first battery container (1010) is different. Additionally, information regarding a reference battery rack for the second battery container (1020) may be predetermined to be the same even if the location inside the second battery container (1020) is different.

[0133] In one embodiment, the first battery container (1010) may include at least one first battery rack (1012) corresponding to the first identification information of the battery rack. A processor (e.g., the processor of the second battery management device (610) and / or the processor (520) of the computing device (500) of FIG. 5) may execute a battery container inspection method on the first battery container (1010). Specifically, the processor may determine whether the identification information for each of the at least one first battery rack (1012) corresponds to the identification information of the reference battery rack. Referring to FIG. 10, since all of the battery racks (1012) included in the first battery container (1010) correspond to the first identification information of the battery rack, the processor may determine that the first battery container (1010) is normal.

[0134] In one embodiment, the second battery container (1010) may include at least one second battery rack (1022). The at least one second battery rack (1022) may include a second_1 battery rack (1024) that does not correspond to the second identification information of the battery rack. The at least one second battery rack (1022) excluding the second_1 battery rack (1024) may include a second_2 battery rack that corresponds to the second identification information of the battery rack. A processor may execute a battery container inspection method on the second battery container (1020). Specifically, the processor may determine one of the at least one second battery rack (1022) as a target battery rack. At this time, the determined target battery rack may be the second_1 battery rack (1024). The processor may determine whether the identification information of the second_1 battery rack (1024) corresponds to the identification information of the reference battery rack. Since the identification information of the 2_1 battery rack (1024) does not correspond to the 2nd identification information of the battery rack, the processor can determine that the 2nd battery container (1020) is abnormal.

[0135] In one embodiment, the processor may perform a battery container inspection method for each of at least one battery container (1010, 1020) included in the energy storage system (600). For example, the processor may perform a battery container inspection method for each of at least one battery container (1010, 1020) according to the internal order of the energy storage system (600) or randomly. If the processor determines that one of the at least one battery container (1010, 1020) is abnormal, it may stop the battery container inspection for the other battery container.

[0136] FIG. 11 is a diagram illustrating an example of a user interface (1100) according to one embodiment of the present disclosure. The user interface (1100) may be output to a display (e.g., a display connected to a processor) through an application that executes a battery container inspection method. In one embodiment, the user interface (1100) may be output when a battery container is determined to be abnormal.

[0137] In one embodiment, the processor may determine that the battery container is abnormal. The processor may output information indicating that the battery container is abnormal. For example, the user interface (1100) may include a pop-up window (1110) indicating that the battery container is abnormal. The pop-up window (1110) may include identification information (1112) of the reference battery container. The pop-up window (1110) may include location information (1114) of the target battery rack. Referring to FIG. 11, the location information (1114) of the target battery rack may indicate that the target battery rack that does not correspond to the identification information of the reference battery container is located in the second position inside the battery container. The pop-up window (1110) may include identification information (1116) of the target battery rack.

[0138] In one embodiment, the user interface (1100) may include information (1120) indicating the inspection order of the battery container. The processor may perform additional inspections on the battery container in addition to the battery container inspection method according to one embodiment. The information (1120) indicating the inspection order of the battery container may be modified in response to the progress of the inspection. During the performance of the inspection of the battery container according to one embodiment, if the battery container is determined to be abnormal, the processor may stop the operation associated with the battery container. In response to the suspension of the operation, the information (1120) indicating the inspection order of the battery container may not be modified.

[0139] If a battery container does not accommodate a battery rack corresponding to the information regarding the reference battery rack, the battery container may be defective. During the assembly process of the battery container, a worker assembling the battery container may incorrectly insert a battery rack into the battery container that does not correspond to the information regarding the reference battery rack. Through the method described above, a battery container determined to be abnormal is considered defective, and a defective battery container can be detected.

[0140] As a result, battery containers of consistent quality can be shipped. In addition, defective battery containers included in the energy storage system can be detected immediately before the energy storage system is put into operation, and failures, accidents, and quality degradation that may occur in the energy storage system can be prevented in advance.

[0141] Although the present invention has been described above by limited embodiments and drawings, the present invention is not limited thereto, and it is obvious that various modifications and variations are possible within the scope of the technical spirit of the present invention and the equivalent scope of the claims described below by those skilled in the art to which the present invention belongs.
