Each battery cell module includes multiple battery cells arranged in sequence, multiple aluminum bars, temperature sensing wires, and multiple temperature sensing plates. The electrodes of adjacent battery cells are connected in series via aluminum bars, thus allowing multiple aluminum bars to be arranged in sequence.

[0003] To monitor the temperature of the battery cells within the module, existing technology involves attaching a temperature sensor to each aluminum core, with a temperature sensing wire connected to each sensor. This requires a large number of temperature sensors during module production, and the manual labor and time required for attaching them are also significant. Therefore, the production cost of this battery module is high, and its production efficiency is low. Utility Model Content

[0004] This application provides a battery cell module and an energy storage container. The battery cell module has temperature acquisition devices installed on half of its internal conductive connectors. Compared with the prior art, which attaches temperature acquisition devices to each aluminum bar, this method can reduce the number of temperature acquisition devices by half while ensuring temperature monitoring of the battery cell during the production of the battery cell module. It can also save labor costs and shorten production time, thus reducing the production cost of the battery cell module and improving its production efficiency.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a battery cell module, comprising: a plurality of battery cells arranged sequentially, a plurality of conductive connectors, and a plurality of temperature sensors. Each conductive connector connects the positive terminal of a battery cell to the negative terminal of an adjacent battery cell along a first direction. The number of temperature sensors is half the number of conductive connectors, and each temperature sensor is disposed on one of the conductive connectors.

[0007] As an optional implementation, along the current flow direction in the battery cell module, a temperature acquisition device is provided at intervals of one of the multiple conductive connectors.

[0008] As an optional implementation, the multiple battery cells are all the same size and shape, and the electrode surface of each battery cell is a rectangular surface, the width direction of the electrode surface is the first direction, and the length direction of the electrode surface is the second direction;

[0009] The multiple battery cells are arranged in two rows; the arrangement direction of the battery cells in each row is the first direction, and the two rows of battery cells have the same number of battery cells;

[0010] The two rows of cells are connected along the second direction;

[0011] On each electrode surface, a positive electrode and a negative electrode are spaced apart along the second direction; on two adjacent electrode surfaces along the first direction, the positive and negative electrodes are arranged in opposite directions.

[0012] Each of the conductive connectors connects the positive terminal of one of the battery cells to the negative terminal of the adjacent battery cell along the first direction, so that the plurality of conductive connectors are arranged in four rows of the same number along the first direction; the plurality of temperature acquisition devices are arranged on the middle two rows of the conductive connectors.

[0013] As an optional implementation, the conductive connector is a rectangular aluminum bar; along the long side of the aluminum bar, the aluminum bar includes two connecting portions, the first surfaces of the two connecting portions being connected to the positive electrode of the battery cell and the negative electrode of the battery cell adjacent to it along the first direction, respectively.

[0014] The temperature acquisition element is disposed on the second side of one of the connecting parts, and the first and second sides of the connecting part are disposed opposite to each other.

[0015] As an optional implementation, the temperature acquisition element is a sheet-shaped temperature sensor, which is attached to the conductive connector.

[0016] As an optional implementation, the battery cell module includes a data transmission line, and multiple temperature acquisition devices are connected to the data transmission line.

[0017] As an optional implementation, the battery cell module includes a control component and a liquid cooling device, the liquid cooling device being connected to multiple battery cells; both the data transmission line and the liquid cooling device are electrically connected to the control component.

[0018] The control component is used to acquire the detected temperature value collected by the data transmission line and compare the detected temperature value with a preset temperature value; when the detected temperature value is higher than the preset temperature value, the control component controls the liquid cooling device to turn on; when the detected temperature value is lower than the preset temperature value, the control component controls the liquid cooling device to turn off.

[0019] As an optional implementation, the cell module includes an integrated busbar connected to the electrode surfaces of a plurality of the cell modules;

[0020] The integrated busbar is provided with multiple limiting holes, and the conductive connector is accommodated in the limiting holes; the number of limiting holes is the same as the number of conductive connectors and they correspond one-to-one.

[0021] The data transmission line is connected to the integrated busbar.

[0022] As an optional implementation, the battery cell module includes multiple voltage acquisition devices, the number of which is the same as the number of conductive connectors, with one voltage acquisition device disposed on one conductive connector; all of the multiple voltage acquisition devices are connected to the data transmission line.

[0023] Secondly, this application provides an energy storage container, which includes the battery cell module described in any of the first aspects above.

[0024] Compared with the prior art, the beneficial effects of this application are at least as follows:

[0025] This battery module comprises multiple battery cells arranged in sequence, multiple conductive connectors, and multiple temperature sensors. The battery cells are used to store electrical energy, achieving energy storage. Each conductive connector connects the positive terminal of one battery cell to the negative terminal of the adjacent battery cell along a first direction. This allows two adjacent battery cells along the first direction to be connected in series.

[0026] Because the number of temperature sensing elements is half the number of conductive connectors, this battery cell module only has temperature sensing elements on half of its internal conductive connectors. Compared to the existing technology where temperature sensing elements are attached to every aluminum core, this reduces the number of temperature sensing elements by half while still ensuring temperature monitoring of the battery cell. It also saves labor costs and shortens production time, thus reducing the production cost and increasing the production efficiency of the battery cell module.

[0027] Since each temperature sensor is located on a conductive connector, this allows for a more dispersed distribution of the limited number of temperature sensors across a larger number of conductive connectors. This enables temperature monitoring at more locations within the battery cell module, thus providing a more accurate reflection of the temperature distribution within the module.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] Energy storage containers are a common type of energy storage device, containing multiple battery cell modules. Each battery cell module includes multiple battery cells arranged in sequence, multiple aluminum bars, temperature sensing wires, and multiple temperature sensing plates. The electrodes of adjacent battery cells are connected in series via aluminum bars, thus allowing multiple aluminum bars to be arranged in sequence.

[0039] To monitor the temperature of the cells within the battery module, existing technology involves attaching a temperature sensing element to each aluminum foil bar, with a temperature sensing wire connected to each element. This results in the same number of temperature sensing elements as aluminum foil bars within the module, requiring a large number of elements to be manufactured. Furthermore, the labor and time required for attaching these elements are also significant, and their cost is relatively high. Therefore, the production cost of this battery module is high, and its production efficiency is low.

[0040] To address the aforementioned technical problems, the battery cell module provided by this utility model solves the problem by incorporating half the number of temperature sensing elements found in existing technologies. Specifically, the battery cell module includes: multiple battery cells arranged sequentially, multiple conductive connectors, and multiple temperature sensing elements. The multiple battery cells are used to store electrical energy to achieve energy storage. Each conductive connector connects the positive terminal of one battery cell to the negative terminal of an adjacent battery cell along a first direction. This allows two adjacent battery cells along the first direction to be connected in series.

[0041] Because the number of temperature sensing elements is half the number of conductive connectors, this battery cell module only has temperature sensing elements on half of its internal conductive connectors. Compared to the existing technology where temperature sensing elements are attached to every aluminum core, this reduces the number of temperature sensing elements by half while still ensuring temperature monitoring of the battery cell. It also saves labor costs and shortens production time, thus reducing the production cost and increasing the production efficiency of the battery cell module.

[0042] Since each temperature sensor is located on a conductive connector, this allows for a more dispersed distribution of the limited number of temperature sensors across a larger number of conductive connectors. This enables temperature monitoring at more locations within the battery cell module, thus providing a more accurate reflection of the temperature distribution within the module.

[0043] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0044] The following provides a detailed description of the specific structure of the battery cell module 110 and various possible implementation methods.

[0045] Figure 1 This is a schematic diagram of the structure of a battery cell module 110 provided in an embodiment of this application. Figure 2 for Figure 1 Exploded view of the structure of part 110 of the core module of China Electronics Technology Group Corporation (CETC). Figure 3 This is a schematic diagram of the structure of multiple conductive connectors 112, multiple temperature acquisition devices 113, data transmission lines 114, and integrated busbars 116. Figure 4 for Figure 3 Top view, Figure 5 for Figure 2 A schematic diagram of the structure when multiple battery cells 111 are arranged in sequence.

[0046] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The battery module 110 includes multiple battery cells 111 arranged in sequence, multiple conductive connectors 112, and multiple temperature acquisition devices 113. Each conductive connector 112 connects the positive terminal of the battery cell 111 to the temperature sensor along a first direction (…). Figure 4 The negative terminals of adjacent cells 111 are connected in the X direction. The number of temperature sensors 113 is half the number of conductive connectors 112, and each temperature sensor 113 is disposed on one conductive connector 112.

[0047] In this embodiment, the battery module 110 includes multiple sequentially arranged battery cells 111, multiple conductive connectors 112, and multiple temperature acquisition devices 113. The multiple battery cells 111 are used to store electrical energy to achieve energy storage. Each conductive connector 112 connects the positive terminal of a battery cell 111 to the negative terminal of an adjacent battery cell 111 along a first direction. This allows two adjacent battery cells 111 along the first direction to be connected in series.

[0048] Since the number of temperature sensing elements 113 is half the number of conductive connectors 112, the battery cell module 110 only has temperature sensing elements 113 on half of the conductive connectors 112 inside. Compared with the existing technology where temperature sensing elements are attached to every aluminum bar, this reduces the number of temperature sensing elements 113 by half while ensuring temperature monitoring of the battery cell 111 during the production of the battery cell module 110. It also saves labor costs and shortens production time, thus reducing the production cost of the battery cell module 110 and improving its production efficiency.

[0049] Since each temperature sensor 113 is located on a conductive connector 112, this allows the limited number of temperature sensors 113 to be distributed more widely across a larger number of conductive connectors 112. This enables temperature monitoring at more locations within the cell module 110, thus providing a more accurate reflection of the temperature distribution within the cell module 110.

[0050] It should be noted that, compared with the existing technology where a temperature sensing element is attached to each aluminum bar, the battery cell module 110 has fewer temperature sensing elements 113, which reduces the connection impedance of the temperature sensing elements 113 and simplifies the structure of the battery cell module 110, thus facilitating the assembly of the battery cell module 110.

[0051] It should also be noted that the number of the aforementioned battery cells 111, conductive connectors 112, and temperature sensing elements 113 is determined according to the design of the battery cell module 110. In a specific battery cell module 110, the number of the aforementioned battery cells 111 is 26, the number of conductive connectors 112 is 24, and the number of temperature sensing elements 113 is 12. Furthermore, the aforementioned battery cells 111, conductive connectors 112, and temperature sensing elements 113 can also be other numbers, and this application embodiment does not limit this.

[0052] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 Along the direction of current flow in the battery cell module 110, a temperature acquisition element 113 is set at intervals of one conductive connector 112 among the multiple conductive connectors 112.

[0053] Since the heating of the battery cell 111 is caused by the thermal effect of the current, that is, the current generates heat due to the resistance of the conductor during its flow. Therefore, the high-temperature region within the battery cell module 110 is mainly concentrated along the current flow path. By positioning the temperature acquisition element 113 along the direction of current flow, it can promptly acquire the temperature of the high-temperature region, thereby providing timely and accurate feedback on any abnormal conditions in the battery cell module 110, thus improving the safety of the battery cell module 110.

[0054] Since the positive and negative terminals of the battery cell 111 are connected to the conductive connector 112 at locations with higher resistance in the current flow path, the thermal effect of the current is more pronounced at these points. This means the conductive connector 112 will have a higher temperature compared to other locations in the current flow path. Placing the temperature sensor 113 on the conductive connector 112 facilitates the acquisition of the highest temperature within the battery cell module 110, thus further improving the safety of the battery cell module 110.

[0055] Since multiple temperature acquisition elements 113 are spaced apart among multiple conductive connectors 112, the total number of temperature acquisition elements 113 can be reduced while the multiple temperature acquisition elements 113 are more evenly distributed along the current flow direction, thereby expanding the temperature monitoring range of the temperature acquisition elements 113 in the cell module 110 and further improving the safety of the cell module 110.

[0056] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The multiple battery cells 111 are all the same size and shape. Each battery cell 111 is provided with an electrode surface 1112 of an electrode 1111, which is a rectangular surface. The width direction of the electrode surface 1112 is the first direction ( Figure 4 The X direction in the middle), the length direction of electrode surface 1112 is the second direction ( Figure 4 Y direction in ).

[0057] Multiple battery cells 111 are arranged in two rows; the arrangement direction of each row of battery cells 111 is a first direction, and the two rows of battery cells 111 have the same number of battery cells 111. The two rows of battery cells 111 are connected along a second direction.

[0058] On each electrode surface 1112, a positive electrode and a negative electrode are arranged at intervals along the second direction; on two adjacent electrode surfaces 1112 along the first direction, the positive and negative electrodes are arranged in opposite directions.

[0059] Each conductive connector 112 connects the positive terminal of a battery cell 111 to the negative terminal of an adjacent battery cell 111 along the first direction, so that the multiple conductive connectors 112 are arranged in four rows of the same number along the first direction; multiple temperature acquisition devices 113 are arranged on the middle two rows of conductive connectors 112.

[0060] In this embodiment, since the multiple cells 111 are all the same size and shape, the electrode surface 1112 of each cell 111 with the electrode 1111 is a rectangular surface. This is beneficial for the arrangement and connection of multiple cells 111, making the assembled cell module more regular in shape, reducing the gaps between cells 111, and improving the energy density of the cell module 110.

[0061] The multiple battery cells 111 are arranged in two rows; the arrangement direction of each row of battery cells 111 is the first direction, and the two rows of battery cells 111 have the same number of cells 111. The two rows of battery cells 111 are connected along the second direction. The battery cell module formed by arranging and connecting multiple battery cells 111 in the above manner is a cuboid, which is beneficial for the spatial layout of the battery cell module 110, thus further improving the energy density of the battery cell module 110.

[0062] Since each electrode surface 1112 has a positive electrode and a negative electrode spaced apart along the second direction, and the positive and negative electrodes on two adjacent electrode surfaces 1112 along the first direction are arranged in opposite directions, this facilitates the arrangement of multiple conductive connectors 112. Specifically, this allows multiple conductive connectors 112 to be staggered along the same current flow path, making full use of the space within the cell module 110.

[0063] Since each conductive connector 112 connects the positive terminal of a battery cell 111 to the negative terminal of an adjacent battery cell 111 along the first direction, the multiple conductive connectors 112 are arranged in four rows of the same number along the first direction; multiple temperature sensors 113 are arranged on the middle two rows of the conductive connectors 112. The temperature at the middle position of the battery cell module is higher than the temperature at the edge position. Arranging multiple temperature sensors 113 on the middle two rows of the conductive connectors 112 in this way is beneficial to monitoring the highest temperature on the battery cell module, thus further improving the safety of the battery cell module 110.

[0064] In addition, the cell module 110 also includes an intermediate insulating sheet 118, two end plates 119, two end insulating sheets 120, and two annular steel cable ties 121. The intermediate insulating sheet 118 is sandwiched between the two rows of cells 111. The two end plates 119 are respectively disposed at both ends of the two rows of cells 111 connected in parallel. An end insulating sheet 120 is disposed between each end plate 119 and the cell 111. The two annular steel cable ties 121 are wound around the two rows of cells 111 connected in parallel, so that the two rows of cells 111 connected in parallel form a whole.

[0065] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The conductive connector 112 is a rectangular aluminum bar; along the long side of the aluminum bar, the aluminum bar includes two connecting portions 1121, the first surfaces of the two connecting portions 1121 being connected to the positive electrode of the battery cell 111 and the negative electrode of the adjacent battery cell 111 along the first direction, respectively. The temperature acquisition element 113 is disposed on the second surface of one of the connecting portions 1121, and the first and second surfaces of the connecting portion 1121 are disposed opposite to each other.

[0066] In this embodiment, the conductive connector 112 is made of aluminum. Aluminum has good conductivity, so the resistance of the aluminum connector is low, which can reduce the thermal effect of the current. Therefore, it can reduce the power loss of the battery module 110 and also help to lower the temperature of the battery module 110.

[0067] Because the aluminum bar is rectangular in shape, it includes two connecting portions 1121 along its long side. The first surfaces of the two connecting portions 1121 are respectively connected to the positive electrode of the battery cell 111 and the negative electrode of the adjacent battery cell 111 along the first direction. This facilitates the arrangement of the aluminum bar, making the connection between the positive electrode of the battery cell 111 and the negative electrode of the adjacent battery cell 111 along the first direction more stable.

[0068] Since the temperature sensor 113 is located on the second side of a connecting part 1121, this avoids conflict between the connection position of the temperature sensor 113 and the electrode 1111, thereby making full use of the surface space of the aluminum battery and thus facilitating the spatial arrangement within the battery cell module 110.

[0069] It should be noted that the conductive connector 112 mentioned above can be an aluminum bar, a copper connector, an iron connector, or a connector made of other conductive materials. This application embodiment does not limit this.

[0070] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The temperature acquisition element 113 is a sheet-shaped temperature sensor, which is attached to the conductive connector 112.

[0071] Compared to general temperature detection elements, this temperature sensor can measure the temperature at a corresponding location and generate temperature information data, which facilitates the transmission of the temperature status at that location to the control components in the form of data. Because the temperature sensor is sheet-shaped, it has a larger surface area for bonding, which helps to ensure a more stable bond between the temperature sensor and the conductive connector 112. Furthermore, the sheet-shaped temperature sensor reduces space requirements, thus contributing to the miniaturization design of the battery module 110.

[0072] It should be noted that the temperature acquisition element 113 mentioned above can also be a sheet-shaped thermistor or other temperature-sensitive components, and this application embodiment does not limit this.

[0073] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The battery module 110 includes a data transmission line 114, and multiple temperature acquisition devices 113 are connected to the data transmission line 114.

[0074] The data transmission line 114 is used to transmit the temperature information data collected by the temperature acquisition unit 113 to the control component, so that the control component can obtain the temperature information data and make a corresponding response. This facilitates the transmission of temperature information. Since multiple temperature acquisition units 113 are connected to the data transmission line 114, the data transmission line 114 can transmit the data collected by each temperature acquisition unit 113, thereby expanding the temperature monitoring range.

[0075] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The battery cell module 110 includes a control component and a liquid cooling device 115, which is connected to multiple battery cells 111. Both the data transmission line 114 and the liquid cooling device 115 are electrically connected to the control component. The control component acquires the detected temperature value collected by the data transmission line 114 and compares the detected temperature value with a preset temperature value. When the detected temperature value is higher than the preset temperature value, the control component controls the liquid cooling device 115 to turn on; when the detected temperature value is lower than the preset temperature value, the control component controls the liquid cooling device 115 to turn off.

[0076] In this embodiment, the battery cell module 110 includes a liquid cooling device 115, which is connected to multiple battery cells 111. When the liquid cooling device 115 is turned on, it can absorb the heat generated by the battery cells 111 during operation, thereby reducing the temperature of the battery cells 111.

[0077] Since the battery module 110 includes a control component, the data transmission line 114 and the liquid cooling device 115 are both electrically connected to the control component. The control component is used to acquire the detected temperature value collected by the data transmission line 114 and compare the detected temperature value with a preset temperature value; when the detected temperature value is higher than the preset temperature value, the control component controls the liquid cooling device 115 to turn on; when the detected temperature value is lower than the preset temperature value, the control component controls the liquid cooling device 115 to turn off. This enables automatic control of the liquid cooling device 115 to turn on or off, thereby enabling the battery module 110 to automatically adjust its temperature.

[0078] It should be noted that the liquid cooling device 115 mentioned above can be a liquid cooling plate or a liquid cooling box, or other types of liquid cooling device 115. This application embodiment does not limit this.

[0079] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The battery module 110 includes an integrated busbar 116, which is connected to the electrode surfaces 1112 of multiple battery cells 111. The integrated busbar 116 is provided with multiple limiting holes 1161, and conductive connectors 112 are accommodated within the limiting holes 1161; the number of limiting holes 1161 and the number of conductive connectors 112 are the same and correspond one-to-one. A data transmission line 114 is connected to the integrated busbar 116.

[0080] In this embodiment, the battery module 110 includes an integrated busbar 116, which is connected to the electrode surfaces 1112 of multiple battery cells 111. The integrated busbar 116 is provided with multiple limiting holes 1161, and conductive connectors 112 are accommodated in the limiting holes 1161. The number of limiting holes 1161 is the same as the number of conductive connectors 112 and they correspond one-to-one. In this way, the limiting holes 1161 can limit the conductive connectors 112, preventing them from moving along the first or second direction, thereby making the structure of the battery module 110 more stable. In addition, the integrated busbar 116 also facilitates the connection of conductive connectors 112 to the electrodes 1111 of the battery cells 111. Specifically, when assembling the battery cell module 110, multiple battery cells 111 can be connected sequentially first, then the integrated busbar 116 can be connected to the electrode surfaces 1112 of the multiple battery cells 111, and finally, multiple conductive connectors 112 can be sequentially placed into multiple limiting holes 1161. This ensures the accuracy of the connection positions of the multiple conductive connectors 112.

[0081] Since the data transmission line 114 is connected to the integrated busbar 116, that is, the data transmission line 114 is attached to the integrated busbar 116. This facilitates the routing of the data transmission line 114 within the battery cell module 110 and also enhances the stability of the battery cell module 110.

[0082] As an optional implementation, in some embodiments, see [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The battery cell module 110 includes multiple voltage acquisition components 117. The number of voltage acquisition components 117 is the same as the number of conductive connectors 112. One voltage acquisition component 117 is disposed on one conductive connector 112. All voltage acquisition components 117 are connected to the data transmission line 114.

[0083] Since the cell module 110 includes multiple voltage acquisition devices 117, which are used to acquire the voltage inside the cell 111, the cell module 110 can monitor the voltage inside the cell 111.

[0084] Since the number of voltage acquisition elements 117 is the same as the number of conductive connectors 112, and one voltage acquisition element 117 is set on one conductive connector 112, that is, each conductive connector 112 is equipped with one voltage acquisition element 117. This allows for voltage monitoring at more locations within the cell module 110, thus providing a more accurate reflection of the voltage distribution at various locations within the cell module 110.

[0085] Since multiple voltage acquisition devices 117 are connected to the data transmission line 114, the data transmission line 114 can be used to transmit the voltage information data acquired by the voltage acquisition devices 117 to the control component, so that the control component can obtain the voltage information data and make a corresponding response, thus facilitating the transmission of voltage information data.

[0086] It should be noted that, in the above Figure 4 On the two middle rows of conductive connectors 112, the right side of each conductive connector 112 is a temperature sensor 113, and the left side is a voltage sensor 117.

[0087] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This application also provides an energy storage container 100, which includes any of the above-mentioned battery cell modules 110.

[0088] In this embodiment, the battery module 110 includes multiple sequentially arranged battery cells 111, multiple conductive connectors 112, and multiple temperature acquisition devices 113. The multiple battery cells 111 are used to store electrical energy to achieve the purpose of energy storage, thus fulfilling the function of the energy storage container 100 in storing electrical energy. Each conductive connector 112 connects the positive terminal of a battery cell 111 to the negative terminal of an adjacent battery cell 111 along the first direction. This allows two adjacent battery cells 111 along the first direction to be connected in series.

[0089] Since the number of temperature sensing elements 113 is half the number of conductive connectors 112, the battery cell module 110 only has temperature sensing elements 113 on half of the conductive connectors 112 inside it. Compared with the existing technology where temperature sensing elements are attached to each aluminum bar, this reduces the number of temperature sensing elements 113 by half while ensuring temperature monitoring of the battery cell 111 during the production of the battery cell module 110. It also saves labor costs and shortens production time, thus reducing the production cost of the battery cell module 110 and increasing its production efficiency. This, in turn, reduces the production cost of the energy storage container 100 and increases its production efficiency.

[0090] Since each temperature sensor 113 is mounted on a conductive connector 112, this allows a limited number of temperature sensors 113 to be distributed more widely across a larger number of conductive connectors 112. This enables temperature monitoring at more locations within the cell module 110, thus providing a more accurate reflection of the temperature distribution within the cell module 110. This allows for control of the energy storage container 100 by understanding the temperature distribution within the cell module 110, thereby improving the automation level of the energy storage container 100.

[0091] It should be noted that the energy storage container 100 may include one or more battery cell modules 110, and this application embodiment does not limit this.

[0092] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0093] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0094] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something,” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “above something” or “on top of something,” but also “on something” or “on top of something” without an intermediate feature or layer therebetween, i.e., directly on something.

[0095] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations rotated 90° or be in other orientations, and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
