[0027] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0028] The power battery pack is detected for abnormalities to obtain diagnostic information. Although the diagnostic information can display the identification information of the abnormal battery cell (the battery cell includes at least one of the battery module and the battery cell), most of the identification information is identification information numbered by the diagnostic software itself. Maintenance personnel need to be familiar with the numbering rules of the diagnostic software and the arrangement rules of the battery cells of the power battery pack in order to match the identification information of the abnormal position in the diagnostic information with the actual position in the power battery pack, making the maintenance of the abnormal power battery pack difficult.

[0029] Based on this, the inventors of the present application discovered that after obtaining the identification information of the abnormal battery cell, the abnormal position corresponding to the identification information can be marked on the layout diagram of the battery cell of the power battery pack, and then the layout diagram of the power battery pack with the abnormal position marked can be displayed, so that maintenance personnel can intuitively find the abnormal position on the power battery pack quickly according to the marked layout diagram, thereby reducing the difficulty of repairing the abnormal power battery pack.

[0030] The present application is applicable to repairing abnormal power battery packs, wherein the abnormal power battery pack may be a power battery pack including battery cells that need to be replaced or repaired, or a power battery pack in which battery cells have failed and need further inspection; the power battery pack can be applied to electric vehicles, as well as to equipment such as drones, industrial robots, electric bicycles and trucks. The present application takes the application of power battery packs to electric vehicles as an example for explanation.

[0031] FIG1 shows schematic diagrams of several applicable scenarios of the method for displaying the abnormal position of a battery provided in an embodiment of the present application. As shown in P1 in FIG1 , the display device for displaying the abnormal position of the battery in this scenario is the display device A1 in FIG1 , and the display device A1 is equipped with a power battery pack diagnostic system for performing abnormal detection on the power battery pack on the electric vehicle and obtaining detection data of the power battery pack. The display device A1 also pre-stores a position distribution map of the battery cells of the power battery pack on the power battery pack, and the display device A1 is also equipped with a display screen; as shown in P2 in FIG1 , the display device for displaying the abnormal position of the battery in this scenario is the display device A2 in FIG1 , and the diagnostic device is equipped with a power battery pack diagnostic system. The battery pack diagnostic system is used to detect abnormalities in the power battery pack of an electric vehicle and obtain detection data for the power battery pack. Display device A2 pre-stores a position distribution map of the battery cells of the power battery pack on the power battery pack, and display device A2 is also equipped with a display screen. As shown in P3 in Figure 1, the display device for the abnormal battery position in this scenario is display device A3 in Figure 1. The diagnostic device is equipped with a power battery pack diagnostic system for detecting abnormalities in the power battery pack of an electric vehicle. Display device A3 is equipped with a display screen. The server stores a position distribution map of the battery cells of the power battery pack on the power battery pack, and display device A3 obtains the position distribution map from the server. The communication method between display device A3 and the server can be based on a wireless routing network or a wired network, such as through a network communication protocol such as http, tcp, udp, or mqtt. The communication method between display device A3 and the diagnostic device can be based on a wireless routing network, a wired network, or wireless Bluetooth communication.

[0032] Among them, the display device (A1, A2 or A3) of the battery abnormality position can be a smart terminal device such as a computer, tablet computer and mobile phone. The power battery pack supports the BMS battery management system (BATTERY MANAGEMENT SYSTEM, referred to as BMS system). The device equipped with the power battery pack diagnostic system is connected to the BMS system of the power battery pack through a dedicated wiring, and then the BMS system of the power battery pack is started through instructions to detect abnormalities of the power battery pack. After the detection is completed, the device equipped with the power battery pack diagnostic system reads the detection data of the power battery pack from the BMS system. Among them, the BMS system refers to the battery management system, which is a system used to monitor, control and protect batteries, including battery status monitoring, temperature control, charge and discharge management and other functions.

[0033] FIG2 is a flow chart of a method for displaying abnormal battery positions according to an embodiment of the present application. The method is executed by the above-mentioned device for displaying abnormal battery positions (such as A1, A2, or A3 shown in FIG1). As shown in FIG2, the method includes the following steps:

[0034] Step 110: Obtain first identification information of an abnormal battery cell in the power battery pack.

[0035] A power battery pack is a combination of multiple battery modules, used to power electric vehicles such as pure electric vehicles and hybrid electric vehicles, or other electric devices. A battery module is a module composed of multiple battery cells, usually including components such as battery cells, connectors, and protection circuits. A battery cell is usually a single cell in a lithium-ion battery. A battery unit includes at least one of a battery module and a battery pack.

[0036] A device equipped with a power battery pack diagnostic system (which may be the display device A1 in FIG. 1 or the diagnostic device in FIG. 1 ) performs abnormality detection on the power battery pack, identifies abnormal battery cells, and obtains identification information of the abnormal battery cells. The device equipped with the power battery pack diagnostic system activates the power battery pack's battery management system (BMS) via a command to detect the power battery pack and obtain circuit condition data, such as temperature, current, or voltage, of each battery cell in the power battery pack. A battery cell whose circuit condition data exceeds a preset range is identified as an abnormal battery cell. The identification information of the abnormal battery cell may be serial number information that sorts the battery cells according to the detection order of the power battery pack's BMS. For example, the identification information of an abnormal battery module may be "M1," "M2," or "M3," and the identification information of an abnormal battery cell may be "#1," "#2," or "#3." "M" and "#" are used to distinguish between battery modules and battery cells, and numbers are used to indicate the detection order. Furthermore, the identification information of the abnormal battery cell may be identification information generated by combining the serial number information and the identification information of the battery cell itself. Among them, the identification information of the battery unit itself is explained by taking the battery cell numbered "6-qaw-54a" as an example. Under the automobile battery number (Chinese standard), "6" means that it is composed of 6 single cells, each battery is 2V, that is, the rated voltage is 12V, "Q" represents the car starting battery, "aw" represents the battery type, "a" represents the dry-charged battery, "w" represents the maintenance-free battery, "54" represents the rated capacity of the battery is 54ah, and "a" indicates that the improvement of the original product is the first improvement.

[0037] Step 120: Obtain a layout diagram corresponding to the power battery pack, wherein the layout diagram is a position distribution diagram of battery cells with second identification information in the power battery pack on the power battery pack.

[0038] Figure 3 shows a schematic diagram of the layout diagram of the power battery pack provided in an embodiment of the present application. The layout diagram is generated in the following manner: a maintenance personnel obtains a structural diagram of the power battery pack (as shown in C1 in Figure 3); when the BMS system inspects the battery cells in sequence, the maintenance personnel uses a circuit detection tool (such as an electric pen) or other means to determine the battery cells being inspected by the BMS system, and labels the battery cells being inspected on the structural diagram according to the determined inspection order to obtain a layout diagram. As shown in C2 in Figure 3, the inspection order of the battery cells is M1, M2, ... M11, "M1", "M2", ..., "M1" is the identification information of the battery cells of the power battery pack.

[0039] Continuing to refer to FIG3 , when the battery unit is a battery module, the layout diagram is shown in FIG3 C2, and the maintenance personnel can quickly find the position of the battery module in the power battery pack according to the identification information of the battery module (such as M1, M2 in C2); when the battery unit is a battery cell, the layout diagram can be a distribution diagram of the battery cell on the battery module, as shown in FIG3 C3, the maintenance personnel first find the position of the battery module on the power battery pack, and then quickly find the position of the battery cell on the battery module according to the identification information of the battery cell (such as #1, #2 in C3), that is, determine the position of the battery cell on the power battery pack; when the battery unit is a battery cell, the layout diagram can be a distribution diagram of the battery cell on the battery module, as shown in FIG3 C3, the maintenance personnel first find the position of the battery module on the power battery pack, and then quickly find the position of the battery cell on the battery module according to the identification information of the battery cell (such as #1, #2 in C3), that is, determine the position of the battery cell on the power battery pack; The layout diagram is a distribution diagram of battery cells on the power battery pack, as shown by C4 in Figure 3. Maintenance personnel can quickly find the position of the battery cells in the power battery pack based on the identification information of the battery cells (such as #5 and #6 in C4); when the battery units are battery modules and battery cells, the layout diagram is a distribution diagram of battery cells and battery modules on the power battery pack, as shown by P4 in Figure 3. At this time, maintenance personnel can quickly find the position of the battery module in the power battery pack based on the identification information of the battery module (such as M1 and M2 in C4), and can also quickly find the position of the battery cell in the power battery pack based on the identification information of the battery cell (such as #5 and #6 in C4).

[0040] The layout diagram may be a two-dimensional (2D) image or a three-dimensional (3D) image.

[0041] Step 130: Mark the battery cells corresponding to the second identification information that matches the first identification information on the layout diagram and display the layout diagram.

[0042] The first identification information is the sorting information of abnormal battery cells in the detection process of the BMS system, and the second identification information is the sorting information of the battery cells determined in advance by the BMS system. The BMS system has a fixed detection order for each battery cell of the power battery pack. Therefore, the detection order in the first identification information and the second identification information corresponds to each other. The detection sequence number in the first identification information can be compared with the detection sequence number in the second identification information, and the battery cell with the second identification information on the layout diagram that is consistent with the detection sequence number of the first identification information can be identified as an abnormal battery cell. The abnormal battery cell is marked on the layout diagram and the layout diagram is displayed, so that maintenance personnel can find the location of the abnormal battery cell on the power battery pack intuitively, accurately and quickly according to the detection results of the BMS system, thereby reducing the difficulty of maintenance.

[0043] Marking an abnormal battery cell on the layout diagram can be achieved by operating on elements on the layout diagram. For example, the position of the element where the abnormal battery cell is located on the layout diagram can be identified, and then the border or text of the element at this position can be bolded or highlighted, or animation can be added.

[0044] When the acquired layout diagram is a 2D image, the display device (such as A1, A2 or A3 as shown in FIG1 ) displays the layout diagram in the form of a 2D image. When the acquired layout diagram is a 3D image, the display device displays the layout diagram in the form of a 3D image. Furthermore, the display device may also be a VR virtual device or a 3D projector to display the layout diagram by projecting a 3D image.

[0045] It should be noted that the embodiment of the present application does not limit the execution order of step 110 and step 120. Step 110 can be executed first, or step 120 can be executed first, or step 110 and step 120 can be executed simultaneously.

[0046] A power battery pack may be composed of dozens of battery modules, and each module is composed of dozens of battery cells. Even if the maintenance personnel know from the diagnostic equipment which battery module and which battery cell has failed, it is difficult to find the specific battery module and battery cell that have failed in the power battery pack. That is, the maintenance personnel determine the position of the abnormal battery cell on the power battery pack based on their own experience, which is not efficient and prone to errors. The embodiment of the present application marks the abnormal battery cells on the layout diagram, so that the maintenance personnel can intuitively find the location of the abnormal battery cell on the power battery pack quickly according to the marked layout diagram, thereby reducing the difficulty of repairing the abnormal power battery pack.

[0047] When the display device of the abnormal battery position is display device A1 or display device A2 as shown in Figure 1, in an optional manner, the above step 120 includes: step 121, searching for a layout diagram corresponding to the type of power battery pack from pre-stored layout diagrams of multiple power battery packs.

[0048] Power battery packs require different layout diagrams depending on the device and device type they are used in. Therefore, different types of power battery packs correspond to different layout diagrams. For display device A1 or display device A2, obtaining a layout diagram for a power battery pack is equivalent to obtaining the layout diagram corresponding to that power battery pack. If a layout diagram is pre-stored on a display device for an abnormal battery location, the display device for the abnormal battery location searches for the layout diagram corresponding to the type of power battery pack from among the pre-stored layout diagrams for the various power battery packs.

[0049] When the display device for the abnormal battery position is the display device A3 shown in FIG1 , in an optional manner, the above step 120 further includes the following sub-steps:

[0050] Step 122: Obtain type information of the power battery pack.

[0051] Different types of power battery packs correspond to different layout diagrams. Display device A3 does not store these layout diagrams and must obtain them from an external device. Therefore, display device A3 must first obtain the power battery pack type information. Continuing with Figure 1, display device A3 can obtain the power battery pack type information in the following ways: A diagnostic device can obtain the type information of the power battery pack being tested from the BMS, and then display device A3 obtains the power battery pack type information from the diagnostic device. Alternatively, a maintenance technician can manually select the type of power battery pack being tested on display device A3, and display device A3 determines the power battery pack type information by reading the maintenance technician's selection.

[0052] Step 124: Send the type information to the server.

[0053] The display device A3 sends the type information of the power battery pack to the server, so that the service weapon can find the layout diagram corresponding to the type information from multiple layout diagrams corresponding to different types of power battery packs based on the received type information.

[0054] Step 126: Receive a layout diagram corresponding to the type information sent by the server.

[0055] The layout diagram received by the display device A3 is the layout diagram corresponding to the type of the power battery pack currently being detected.

[0056] If the layout diagram is a 2D image, then in an optional manner, the layout diagram is an image in SVG format, the SVG format image includes multiple SVG elements, and the battery cell with the second identification information is represented on the layout diagram by at least some of the SVG elements. The above step 130 includes the following sub-steps:

[0057] Step 131: Search for an SVG element containing second identification information matching the first identification information from multiple SVG elements in the layout diagram.

[0058] In an SVG image, an SVG element is used to represent a battery cell, and the identification information of the battery cell is the text content in the SVG element. Therefore, the identification information of the abnormal battery cell can be used to perform regular matching on multiple SVG elements to find the SVG element containing the identification information of the abnormal battery cell.

[0059] Step 133 : Mark the found SVG elements to complete the marking of the battery cells on the layout diagram.

[0060] SVG is based on XML, so JavaScript can be used to add events or animation effects to SVG elements to mark the SVG elements corresponding to abnormal battery cells on the SVG image.

[0061] Step 135: Display the marked layout diagram.

[0062] If the layout diagram is a 2D image, preferably, the layout diagram is set to SVG format. When the layout diagram in SVG format is displayed, JavaScript uses XML to describe the SVG image, so that the display device can obtain the SVG element and its text content and thus determine the SVG element corresponding to the abnormal battery cell through regular matching; while other image formats, such as png, jpg or bmp, etc., when the layout diagram is displayed, JavaScript jumps to the corresponding image through the img tag, so that the display device cannot directly find the abnormal battery cell from the layout diagram. That is, it is necessary to first perform image recognition on the display diagram to extract the text content, and then mark the location of the text content matching the second identification information from the display diagram. The process is very complicated and time-consuming.

[0063] FIG4 is a flow chart showing a method for displaying abnormal battery positions according to another embodiment of the present application. The method is executed by the above-mentioned device for displaying abnormal battery positions (such as A1, A2, or A3 shown in FIG1 ). As shown in FIG4 , the method includes the following steps:

[0064] Step 210 : Acquire and display detection data of the power battery pack, wherein the detection data includes abnormal battery cells with first identification information.

[0065] The BMS system detects the power battery pack and obtains detection data of the power battery pack. The display device at the battery abnormality location displays the acquired detection data. In addition to including abnormal battery cells with first identification information, the detection data may also include battery cells with second identification information. In addition to the identification information of the battery cells, the detection data may also include data such as the voltage, current, and temperature values ​​measured during the detection of the battery cells. In other words, the display device at the battery abnormality location can display all the detection data of the BMS system, allowing maintenance personnel to understand the specific operating conditions of each battery cell in the power battery pack.

[0066] Step 220 : Responding to the display instruction of the abnormal battery cell, obtaining first identification information from the detection data.

[0067] Maintenance personnel select the abnormal battery cell to be viewed through the display device of the abnormal battery position. The selection can be made through the physical buttons on the display device of the abnormal battery position, through the interactive interface provided on the display device of the abnormal battery position, or through gestures.

[0068] Maintenance personnel can simultaneously view the locations of multiple abnormal battery cells on the power battery pack. For example, maintenance personnel can view all detected abnormal battery cells by clicking the total display key for the abnormal battery module. The display device for the battery abnormal location receives a display instruction for the multiple detected abnormal battery cells and marks the multiple abnormal battery cells on the layout diagram. Maintenance personnel can also selectively view the location of a single abnormal battery cell on the power battery pack. For example, maintenance personnel can view the location of a specific abnormal battery cell on the power battery pack by selecting the specific abnormal battery cell. The display device for the battery abnormal location receives a display instruction for the single abnormal battery cell selected by the maintenance personnel and marks the selected single abnormal battery cell on the layout diagram. The display device for the battery abnormal location obtains the first identification information of the corresponding abnormal battery cell from the detection data according to the display instruction corresponding to the maintenance personnel's operation.

[0069] Step 230: Obtain and display a layout diagram corresponding to the power battery pack.

[0070] The display device at the abnormal battery location displays the detection data. After the maintenance personnel perform the operation, the display device at the abnormal battery location displays the layout diagram again. The layout diagram and the detection data can be displayed separately on the same display interface, or the layout diagram can be displayed in the form of a pop-up window on the detection data interface, or the display interface originally only displays the detection data and then only displays the layout diagram after refreshing.

[0071] Step 240 : Mark the battery cells corresponding to the second identification information that matches the first identification information in the displayed layout diagram.

[0072] Among them, step 240 is similar to step 130. Therefore, the specific implementation of step 240 can refer to step 130 and will not be repeated here.

[0073] The display device of the battery abnormality location not only displays the detection data, but also displays a layout diagram with abnormal battery cells marked, which can enable maintenance personnel to understand the operation status of the power battery pack more comprehensively and intuitively.

[0074] The detection data includes multiple abnormal battery cells with first identification information. When the maintenance personnel selects a specific abnormal battery cell to be checked, in an optional manner, step 220 includes:

[0075] Step 221 : In response to a display instruction of an abnormal battery cell, first identification information of the abnormal battery cell corresponding to the display instruction is obtained from detection data.

[0076] When the abnormal battery cell selected for viewing by the maintenance personnel is a specific abnormal battery cell, the display device at the abnormal battery location receives a display instruction for the single abnormal battery cell selected by the maintenance personnel, and the display device at the abnormal battery location obtains the first identification information of the abnormal battery cell and marks it on the layout diagram.

[0077] A battery unit includes multiple battery modules, and a battery module includes multiple battery cells. FIG5 shows a flow chart of a method for displaying an abnormal battery position according to another embodiment of the present application. The method is performed by the above-mentioned device for displaying an abnormal battery position (such as A1, A2, or A3 shown in FIG1 ). As shown in FIG5 , the method includes the following steps:

[0078] Step 310 : Acquire third identification information of an abnormal battery module and fourth identification information of an abnormal battery cell in the power battery pack.

[0079] Preferably, abnormal modules and abnormal battery cells use different numbering methods to determine identification information. For example, the identification information of the abnormal battery module can be "M1", "M2" or "M3", and the identification information of the abnormal battery cell can be "#1", "#2" or "#3". "M" and "#" are used to distinguish between battery modules and battery cells, and digital identification is used to identify the detection order.

[0080] Step 320: Obtain a module layout diagram of the battery module and a cell layout diagram of the battery cells corresponding to the power battery pack, wherein the module layout diagram is a position distribution diagram of the battery modules with the fifth identification information in the power battery pack on the power battery pack, and the cell layout diagram is a position distribution diagram of the battery cells with the sixth identification information on the battery module to which they belong.

[0081] Continuing with Figure 3, C2 in Figure 3 illustrates the module layout diagram, which shows the positional distribution of each battery module (M1-M11) on the power battery pack. C3 in Figure 3 illustrates the cell layout diagram, which shows the positional distribution of each battery cell on its respective battery module. For example, battery module M1 has battery cells #1 and #2. Furthermore, C4 in Figure 3 illustrates the cell layout diagram, which shows the positional distribution of each battery cell (#1-#7) on the power battery pack.

[0082] Step 330 , in response to the display instruction for the abnormal battery module, mark the battery module corresponding to the fifth identification information that matches the third identification information of the abnormal battery module corresponding to the display instruction on the module layout diagram and display the module layout diagram.

[0083] When the display instruction is set to display multiple abnormal battery modules detected, the display instruction corresponds to the multiple abnormal battery modules detected, and the multiple abnormal battery modules detected are marked on the module layout diagram and the module layout diagram is displayed. For example, the maintenance personnel can operate the set abnormal battery module display main key to mark multiple abnormal battery modules in the module layout diagram, so as to view the position distribution of multiple abnormal battery modules on the power battery pack at the same time; when the display instruction is set to display the abnormal battery module selected by the maintenance personnel, the abnormal battery module corresponding to the display instruction is the battery module selected by the maintenance personnel, and the battery module selected by the maintenance personnel is marked on the module layout diagram and the module layout diagram is displayed. For example, the maintenance personnel can select the abnormal battery module through the touch screen of the display device of the battery abnormal position, and after the display device of the battery abnormal position obtains the identification information of the selected abnormal battery module, the abnormal battery module is marked in the module layout diagram and the module layout diagram is displayed, so that the maintenance personnel can view the position of the specific abnormal battery module on the power battery pack.

[0084] Step 340, in response to the display instruction of the abnormal battery cell, search for the fourth identification information of the abnormal battery cell belonging to the marked battery module and the cell layout diagram corresponding to the marked battery module, mark the battery cell corresponding to the sixth identification information matching the found fourth identification information on the found cell layout diagram and display the marked cell layout diagram.

[0085] When the display instruction is set to display multiple abnormal battery modules detected, the marked battery module is the multiple abnormal battery modules detected; when the display instruction is set to display the abnormal battery module selected by the maintenance personnel, the marked battery module is the battery module selected by the maintenance personnel.

[0086] Similarly, when the display instruction of the abnormal battery cell is set to display multiple abnormal battery cells detected, the display instruction corresponds to the multiple abnormal battery cells detected. At this time, the cell layout diagram corresponding to the marked battery module can be a distribution diagram of the battery cells on the power battery pack (as shown in C4 in Figure 3). The multiple abnormal battery cells detected are marked on the cell layout diagram and the cell layout diagram is displayed. For example, maintenance personnel can operate the set abnormal battery cell display main key to mark multiple abnormal battery cells in the cell layout diagram, so as to view the position distribution of multiple abnormal battery cells on the power battery pack at the same time.

[0087] When the display instruction is set to display the abnormal battery cells selected by the maintenance personnel, the abnormal battery cells selected by the maintenance personnel can be multiple abnormal battery cells belonging to a specific abnormal battery module selected by the maintenance personnel, or can be a specific abnormal battery cell selected by the maintenance personnel within the selected specific abnormal battery module. In this case, the cell layout diagram corresponding to the marked battery module is the cell layout diagram of the specific abnormal battery module selected by the maintenance personnel. For example, as shown in C3 in Figure 3, if M2 is the specific abnormal battery module selected by the maintenance personnel, the cell layout diagram corresponding to the marked battery module is the position distribution of battery cells #1 and battery cells #2 in battery module M2.

[0088] When maintenance personnel need to display the location of an abnormal battery cell, they can display the selected abnormal battery cell, or they can directly display multiple abnormal battery cells detected without making any selection. The selection of abnormal battery cells can be based on the selected abnormal battery module, that is, the abnormal battery cell is selected from the selected abnormal battery module; or they can be selected from all battery cells. The direct display of multiple abnormal battery cells detected without selecting an abnormal battery cell can be based on the display of multiple abnormal battery cells of the selected abnormal battery module; or all abnormal battery cells can be displayed. The selected abnormal battery module can be the abnormal battery module marked in the module display diagram, or it can be the abnormal battery module selected again by the maintenance personnel from the multiple marked abnormal battery modules in the module display diagram.

[0089] Specifically, the layout diagram of the marker monomers in the embodiment of the present application is exemplarily described in combination with step 330, step 340 and the following Table 1:

[0090] Table 1:

[0091] Please refer to Table 1. In step 330, the maintenance personnel operates the abnormal battery module display key set so that multiple abnormal battery modules are marked in the module layout diagram. That is, the battery modules marked in step 330 are the three abnormal battery modules M1, M2 and M8. In step 340, the battery modules marked are the three abnormal battery modules M1, M2 and M8. Among them, M1 (#1) identifies the abnormal battery cell in the abnormal battery module as #1. In addition, the maintenance personnel can also select an abnormal battery module (M8) from the three abnormal battery modules M1, M2 and M8 as the marked battery module in step 340. The display instruction of the abnormal cell can be multiple detected abnormal battery modules. The display instruction of the abnormal battery cells (#1, #2, #4 and #5) can also be the display instruction of an abnormal battery cell (#1) selected by the maintenance personnel from #1, #2, #4 and #5; in step 330, the maintenance personnel selects a specific battery module (M8) from multiple abnormal battery modules (M1, M2 and M8) to mark it, and in step 340, the marked battery module is consistent with the battery module marked in step 330, and the display instruction of the abnormal cell can be the display instruction of multiple detected abnormal battery cells (#4 and #5), or the display instruction of an abnormal battery cell (#4) selected by the maintenance personnel from #4 and #5.

[0092] Therefore, when displaying the location of abnormal battery cells, flexible display options can be set according to actual needs to facilitate maintenance work by maintenance personnel.
