[0055] See also Figures 1 to 3The present invention provides an energy storage power supply 10. The energy storage power supply 10 includes a housing 11, at least one battery cell 13, a fixing member 15, and an electrical connector 17. A positioning portion 111 is provided on the inner wall of the housing 11. A first end 131 of the at least one battery cell 13 is inserted into the positioning portion 111. A second end 132 of the at least one battery cell 13, opposite to the first end 131, is provided with two electrodes 133. The fixing member 15 fixes the second end 132 of the at least one battery cell 13. The electrical connector 17 is electrically connected to the second end 132 of the at least one battery cell 13.

[0056] In the aforementioned energy storage power supply 10, a positioning portion 111 is provided on the inner wall of the housing 11. The first end 131 of the battery cell 13 can be directly inserted into the positioning portion 111, without requiring a bracket for fixing and then assembling the battery cell 13 to the housing 11. This saves on components and installation procedures, and eliminates the need for reserved installation space in the housing 11, thereby reducing the cost and size of the energy storage power supply 10. Furthermore, the second end 132 of the battery cell 13 is secured by a fixing member 15 and connected to an electrical connector 17, thereby achieving overall fixation and electrical connection of the battery cell 13 within the housing 11.

[0057] Specifically, in one embodiment, Figure 1 and Figure 2 As shown, at least a portion of the shell 11 of the energy storage power supply 10 is surrounded to form a receiving cavity 112. A positioning portion 111 is provided in the receiving cavity 112. The positioning portion 111 can be used to guide and fix one end of at least one battery cell 13. Compared with the method of fixing the two ends of the battery cell 13 respectively by two brackets, the use of brackets can be reduced, the assembly steps can be saved, and the production cost can be reduced.

[0058] In one embodiment, Figure 1 As shown, the battery cell 13 includes a first end 131 and a second end 132 arranged opposite to each other, so that the energy storage power supply 10 ensures the stability of the battery cell 13 in the energy storage power supply 10 by fixing the first end 131 and the second end 132 of the battery cell 13 respectively.

[0059] It can be understood that the first end 131 and the second end 132 of the battery cell 13 can be the lower end and the upper end, the left end and the right end, the front end and the rear end or other two ends arranged opposite to each other of the corresponding battery cell 13, respectively. It is related to factors such as the shape or placement direction of the battery cell 13. The first end 131 and the second end 132 can be fixed respectively by the positioning portion 111 and the fixing member 15, so that the battery cell 13 is safely placed in the energy storage power supply 10 to ensure the normal operation of the energy storage power supply 10. No specific limitation is made here.

[0060] In one embodiment, a positioning portion 111 is provided on the inner wall of the shell 11, which is equivalent to merging one of the brackets into the shell 11, that is, the positioning portion 111 and the shell 11 are an integral structure and cannot be disassembled, so that one end of the battery cell 13 is directly installed on the shell 11, thereby realizing a "cell-to-pack" (CTP) structure, which is a module-free technology. The assembly module (wherein the module includes components such as brackets and bolts) can be omitted or reduced, and there is no need to reserve installation space, which can achieve cost reduction and product miniaturization.

[0061] In one embodiment, the positioning portion 111 can be set at different positions on the inner wall of the shell 11, such as the inner side wall, inner bottom wall or other positions of the shell 11, so that the first end 131 of at least one battery cell 13 is fixed on the positioning portion 111, thereby ensuring that one end of at least one battery cell 13 is stably set in the energy storage power supply 10, without specific limitation here.

[0062] For example, in one example, the positioning portion 111 may be a positioning groove having a shape and size matching that of the first end 131, such as Figure 1 As shown, for example, the positioning portion 111 is a cylindrical slot, which can enable the first end 131 of at least one battery cell 13 to form an interference fit with a corresponding number of positioning slots, thereby improving the connection stability between the battery cell 13 and the positioning portion 111.

[0063] In one embodiment, Figure 1 As shown, the energy storage power supply 10 includes a fixing member 15, which is detachably connected to the energy storage power supply 10 and arranged opposite to the positioning portion 111. The fixing member 15 can be used to fix the second end 132 to ensure that the second end 132 is stably arranged in the energy storage power supply 10, thereby improving the overall stability of at least one battery cell 13 and further ensuring the safe operation of the energy storage power supply 10.

[0064] In one embodiment, Figure 1 As shown, the electrical connector 17 is a busbar, and is used to connect multiple battery cells 13 in series and / or in parallel when there are multiple battery cells 13 .

[0065] In one embodiment, Figure 1 As shown, there are multiple electrical connectors 17, each of which is provided with multiple positioning holes (not shown in the figure), and the fixing member 15 is provided with multiple positioning columns (not shown in the figure) corresponding to the multiple positioning holes, so that the positioning holes and the positioning columns are correspondingly connected. For example, the positioning holes and the positioning columns can form an interference fit, or can be combined by screws, or can be connected by other means, thereby ensuring that the electrical connector 17 is fixedly installed on the fixing member 15, and the connection stability is good.

[0066] In one embodiment, the fixing member 15 is formed with a plurality of through holes 1511 to ensure that the second end 132 of at least one battery cell 13 is exposed through the plurality of through holes 1511 so that the electrical connector 17 is electrically connected to the at least one battery cell 13, thereby ensuring that the energy storage power supply 10 discharges outward to output electrical energy or charges inward to input electrical energy.

[0067] It is understandable that Figure 1 and Figure 2 As shown, the electrical connector 17 can be electrically connected to at least one battery cell 13 by welding, so that the electrical connector 17 is connected in series and / or in parallel with at least one battery cell 13, so that the energy storage power supply 10 provides a suitable power supply voltage to meet user requirements.

[0068] For example, in one example, the electrical connector 17 can connect the positive poles of at least one battery cell 13 to form a total positive wiring port, and connect the negative poles to form a total negative wiring port, that is, the electrical connector 17 is connected in parallel with at least one battery cell 13, so that at least one battery cell 13 forms a stable output power supply, thereby ensuring the normal operation of the energy storage power supply 10 and good durability.

[0069] In another example, the electrical connector 17 can connect the positive poles and the negative poles of at least one battery cell 13 alternately in sequence, so that the positive pole and the negative pole connected to the two ends of the electrical connector 17 are respectively the positive wiring port and the negative wiring port, that is, the electrical connector 17 is connected in series with at least one battery cell 13, so that at least one battery cell 13 forms a high-voltage output power supply, thereby ensuring that the user's power needs are met.

[0070] In one embodiment, Figure 1 and Figure 2 As shown, the energy storage power supply 10 further includes a collection board 19. The collection board 19 is provided with nickel strips arranged in a column shape along the left and right directions. The nickel strips can be connected and fixed to the electrical connector 17 by welding, for example, the welding method can be laser welding, etc., so as to ensure that the energy storage power supply 10 timely collects and obtains the status information of each battery cell 13. The status information of the battery cell 13 may include information such as temperature, current or voltage, thereby ensuring the safe operation of the energy storage power supply 10.

[0071] That is, after the electrical connectors 17 are welded to the battery cells 13, the collection board 19 can be fixed to the corresponding position on the electrical connector 17 using screws. After the collection board 19 is fixed, the nickel strip of the collection board 19 can be connected to the electrical connector 17 using an electrical connection method such as laser welding, thereby achieving electrical connection between the collection board 19 and the electrical connector 17.

[0072] It is worth noting that the first end 131 can be a pole-free end, and the second end 132 can be a pole-equipped end with at least two poles of different electrical properties, so that the energy storage power supply 10 is only provided with an electrical connector 17 and a collection board 19 at the second end 132 of the battery cell 13, so that the electrical connector 17 and the collection board 19 are respectively electrically connected to the positive and negative poles located at the second end 132 of the battery cell 13 to ensure normal charging and discharging of the battery cell 13, thereby saving the number and arrangement space of the electrical connector 17 and the collection board 19, which is conducive to the miniaturized design of the energy storage power supply 10.

[0073] See also Figures 4 to 11 In some embodiments, the positioning portion 111 is located on the inner bottom wall 113 or the inner side wall 115 of the shell 11 .

[0074] In this way, the battery cell 13 is ensured to be stably placed on the inner bottom wall 113 or the inner side wall 115 of the housing 11 to meet different product installation requirements.

[0075] Specifically, in one embodiment, Figures 4 to 7 As shown, the positioning portion 111 is located on the inner bottom wall 113 of the shell 11, that is, the positioning portion 111 does not contact the side of the shell 11, and can form a space for placing the battery cell 13 perpendicular to the paper surface. The inner bottom wall 113 of the shell 11 and the baffle (not shown) forming the positioning portion 111 are surrounded to form a stable support structure, thereby ensuring that the first end 131 of the battery cell 13 is stably placed on the positioning portion 111.

[0076] It can be understood that the inner bottom wall 113 of the housing 11 can serve as a support base to support the battery cell 13 placed in the positioning portion 111 , thereby improving the placement stability of the battery cell 13 and ensuring the safe operation of the battery cell 13 .

[0077] In one example, Figure 5 As shown, the battery cell 13 may be in a sheet or block shape, and may be installed in the positioning portion 111 placed in the rectangular slot to ensure the stability of the battery cell 13 .

[0078] In another example, Figure 4 、 Figure 6 and Figure 7 As shown, the battery core 13 may also be cylindrical, and can be installed in the positioning portion 111 placed in the cylindrical slot to ensure the stability of the battery core 13 .

[0079] In other examples, the battery cell 13 may also be in other shapes to match the positioning portion 111 of a corresponding shape, thereby ensuring stable placement of the battery cell 13 , which is not specifically limited here.

[0080] In one embodiment, Figures 8 to 11As shown, the positioning portion 111 is located on the inner wall 115 of the shell 11, that is, the positioning portion 111 is in direct contact with the side of the shell 11, and a space for placing the battery cell 13 perpendicular to the paper surface can be formed, so that the inner wall 115, the inner bottom wall 113 and the baffle (not shown) forming the positioning portion 111 of the shell 11 are surrounded to form a stable support structure, thereby ensuring that the first end 131 of the battery cell 13 is stably placed on the positioning portion 111.

[0081] It can be understood that the inner side wall 115 of the shell 11 can be equivalent to a part of the baffle, which can be used to limit and fix the battery cell 13 so that the battery cell 13 can be stably placed in the positioning portion 111. At the same time, the inner bottom wall 113 of the shell 11 can serve as a supporting base, which can support the battery cell 13 placed in the positioning portion 111 to improve the placement stability of the battery cell 13, thereby ensuring the safe operation of the battery cell 13.

[0082] In one example, Figure 8 and Figure 9 As shown, the battery cell 13 may be in a sheet or block shape, and may be installed in the positioning portion 111 placed in the rectangular slot to ensure the stability of the battery cell 13 .

[0083] In another example, Figure 10 As shown, the battery core 13 may also be cylindrical, and can be installed in the positioning portion 111 placed in the cylindrical slot to ensure the stability of the battery core 13 .

[0084] In another example, Figure 11 As shown, the battery core 13 may also be in a hollow cylindrical shape, and can be installed in the annular positioning portion 111 to ensure the stability of the battery core 13 .

[0085] In other examples, the battery cell 13 may also be in other shapes to match the positioning portion 111 of a corresponding shape, thereby ensuring stable placement of the battery cell 13 , which is not specifically limited here.

[0086] In summary, the positioning portion 111 is located on the inner bottom wall 113 or the inner side wall 115 of the shell 11, which can save the use and installation space of the bracket, thereby increasing the placement number and energy density of the battery cells 13 and having good practicality.

[0087] See also Figure 4 In some embodiments, the inner bottom wall 113 of the housing 11 is formed with a plurality of posts 1131 arranged in an array, and the positioning portion 111 is a positioning groove formed between two adjacent rows and two columns of the posts 1131 .

[0088] In this way, the first end 131 of the cylindrical battery cell 13 is guided and fixed, which improves safety.

[0089] Specifically, in one embodiment, the plurality of posts 1131 are arranged in multiple rows and columns, and positioning grooves are defined between two adjacent rows and columns of posts 1131 to ensure that the plurality of battery cells 13 are spaced apart and placed for better safety.

[0090] It can be understood that by forming positioning grooves arranged at intervals by multiple clamping columns 1131, multiple battery cells 13 can be placed at intervals, reducing problems such as thermal expansion caused by direct contact between multiple battery cells 13, and reducing the situation where multiple battery cells 13 are squeezed and deformed by each other due to collision of the energy storage power supply 10, thereby reducing safety risks.

[0091] In one embodiment, Figure 4 As shown, cylindrical slots may be defined between two adjacent rows and two columns of the clamping posts 1131 to ensure that the cylindrical battery cells 13 are stably placed, thereby improving the stability of the cylindrical battery cells 13 .

[0092] In detail, the outer peripheral wall of each clamping column 1131 forms an arc surface to surround a cylindrical slot, so that the cylindrical slot matches the outer peripheral wall of the battery cell 13, thereby ensuring the connection effect between the battery cell 13 and the positioning part 111 and reducing shaking.

[0093] In other embodiments, the positioning grooves may also be in other shapes, such as a rectangle, etc., to ensure that battery cells 13 of different shapes are stably placed, and no specific limitation is made here.

[0094] In one embodiment, Figure 1 and Figure 4 As shown, preferably, the height of the clamping column 1131 is less than or equal to Figure 1 The height of the housing 11 is to ensure that the height of the positioning portion 111 is less than or equal to Figure 1 The height of the housing 11 is greater than the height of the housing 11, thereby ensuring that the battery core 13 is stably placed on the positioning portion 111. Of course, the height of the clamping column 1131 can also be greater than Figure 1 The height of the housing 11 is such that the height of the positioning portion 111 is greater than Figure 1 The height of the housing 11 is regulated, and other connectors are used to ensure that the electronic components (such as an inverter, etc.) located on the second end 132 of the battery cell 13 are stably fixed inside the energy storage power supply 10, without any specific restrictions.

[0095] in, Figure 1 The shell 11 can be a unilateral shell 11, such as a lower shell integrated with the positioning portion 111, or a left shell integrated with the positioning portion 111, or a unilateral shell 11 in other orientations, and no specific limitation is made here.

[0096] See also Figure 6In some embodiments, the inner bottom wall 113 of the shell 11 is formed with a plurality of limiting strips 1132 , and the plurality of limiting strips 1132 include serpentine side surfaces 1133 , and the positioning portion 111 is a positioning groove formed between two adjacent serpentine side surfaces 1133 .

[0097] In this way, the first end 131 of the cylindrical battery cell 13 is inserted into the positioning groove, and the side surface of the battery cell 13 is tightly arranged against the serpentine side surface 1133 , thereby improving the stability of the battery cell 13 .

[0098] Specifically, in one embodiment, a plurality of limit bars 1132 are arranged in multiple rows on the inner bottom wall 113 of the shell 11, and each limit bar 1132 includes two serpentine side surfaces 1133 arranged opposite to each other to form a plurality of positioning grooves spaced apart in the row direction and a plurality of positioning grooves staggered in the column direction, thereby ensuring that a plurality of battery cells 13 are spaced apart and placed in the positioning portion 111, which has good safety.

[0099] It can be understood that by arranging the positioning grooves at intervals on the serpentine side surface 1133, the multiple battery cells 13 can be placed at intervals, reducing problems such as thermal expansion caused by direct contact between the multiple battery cells 13, and reducing the situation where the energy storage power supply 10 causes the multiple battery cells 13 to be squeezed and deformed by each other due to collision, thereby reducing safety risks.

[0100] In one embodiment, Figure 6 As shown, the limit bars 1132 can be arranged in three rows along the left and right directions, and a plurality of cylindrical slots can be defined between the two serpentine sides 1133 of each limit bar 1132 to ensure that the plurality of cylindrical battery cells 13 are stably placed and spaced at a safe distance, thereby improving the stability of the cylindrical battery cells 13.

[0101] In other embodiments, the number of the limiting bars 1132 may be other, and the positioning grooves may be other shapes, such as rectangular, etc., to ensure that battery cells 13 of different shapes are stably placed, and no specific limitation is made here.

[0102] See also Figures 8 to 11 In some embodiments, the inner side wall 115 of the shell 11 is formed with an integrated bracket 1151 , and the positioning portion 111 is a positioning groove formed on the integrated bracket 1151 .

[0103] In this way, the battery cell bracket is saved, and the first end 131 of the battery cell 13 is ensured to be stably fixed by the inner wall 115 of the housing 11 , thereby reducing costs.

[0104] Specifically, in one embodiment, Figures 8 to 11As shown, the inner wall 115 of the shell 11 is formed with an integrated bracket 1151, so that the inner wall 115 and the integrated bracket 1151 form a positioning portion 111, so that the first end 131 of the battery cell 13 is limited and placed on the positioning portion 111, and supported by the inner bottom wall 113, thereby ensuring the stability of the battery cell 13.

[0105] In one embodiment, the housing 11 and the integrated bracket 1151 can be integrally formed by injection molding to save external brackets and installation space, and to improve the structural strength of the housing 11 and the integrated bracket 1151, thereby ensuring the safe placement of the battery cell 13.

[0106] In other embodiments, the housing 11 and the integrated bracket 1151 may also be formed in other ways to ensure the safe placement of the battery cell 13, which is not specifically limited here.

[0107] In one embodiment, Figure 8 As shown, an integrated bracket 1151 can be formed on two opposite inner side walls 115 in the shell 11 to form a plurality of rectangular positioning grooves, which can be used to place sheet-shaped or square-shaped battery cells 13, thereby ensuring the stability and safety of the battery cells 13.

[0108] In one embodiment, Figure 9 As shown, the integral bracket 1151 can also be formed on a single inner wall 115 in the housing 11 (as shown in FIG. Figure 9 ), can also be formed on two adjacent inner side walls 115 or three adjacent inner side walls 115 in the shell 11 (not shown), and the integrated bracket 1151 is a square frame to form a plurality of rectangular positioning grooves, which can be used to place sheet-shaped or square-shaped battery cells 13, thereby ensuring the stability and safety of the battery cells 13, and no specific restrictions are made here.

[0109] In one embodiment, Figure 10 As shown, the integral bracket 1151 can be formed on a single inner wall 115 in the housing 11 (eg, Figure 10 ), can also be formed on two adjacent inner side walls 115 or three adjacent inner side walls 115 in the shell 11 (not shown), and the integrated bracket 1151 can define a plurality of cylindrical positioning grooves, which can be used to place the cylindrical battery cells 13, thereby ensuring the stability and safety of the battery cells 13, and no specific restrictions are made here.

[0110] In one embodiment, Figure 11 As shown, the integral bracket 1151 can be formed on a single inner wall 115 in the housing 11 (eg, Figure 11), can also be formed on two adjacent inner side walls 115 or three adjacent inner side walls 115 in the shell 11 (not shown), and the integrated bracket 1151 can be a cylinder and an outer frame arranged in an array, which can define a plurality of annular positioning grooves, which can be used to place the hollow cylindrical battery cell 13, thereby ensuring the stability and safety of the battery cell 13, and no specific limitation is made here.

[0111] In summary, the housing 11 and the integrated bracket 1151 are an integrated structure, which can save external brackets and installation space, thereby ensuring the stable placement of the battery cell 13 and reducing costs.

[0112] See also Figures 4 to 11 In some embodiments, the positioning groove is circular or rectangular.

[0113] In this way, it is ensured that both the cylindrical battery core 13 and the rectangular battery core 13 can be stably placed in the positioning grooves of corresponding shapes, thereby improving the adaptability and safety of battery cores 13 of different shapes.

[0114] Specifically, in one embodiment, Figure 4 、 Figure 6 、 Figure 7 、 Figure 10 and Figure 11 As shown, the positioning groove is circular and can be used to place the cylindrical battery core 13 to ensure that the cylindrical battery core 13 is matched and connected with the circular positioning groove, thereby improving the safety of the cylindrical battery core 13.

[0115] In another embodiment, Figure 5 、 Figure 8 and Figure 9 As shown, the positioning groove is rectangular and can be used to place sheet-shaped or square-shaped battery cells 13 to ensure that the sheet-shaped or square-shaped battery cells 13 are matched and connected with the rectangular positioning groove, thereby improving the safety of the sheet-shaped or square-shaped battery cells 13.

[0116] It can be understood that, in one example, the battery cell 13 can form an interference fit with the positioning groove to ensure that the battery cell 13 is stably placed, thereby ensuring that the battery cell 13 works safely.

[0117] In another example, when the battery cell 13 is placed in the positioning groove, colloid may be injected to ensure that the battery cell 13 is stably connected to the positioning groove, thereby ensuring that the battery cell 13 works safely.

[0118] The colloid may be a thermally conductive adhesive, which can enhance the connection effect of the battery core 13 on the one hand, and discharge the heat generated by the battery core 13 through the housing 11 on the other hand, so that the battery core 13 can effectively dissipate heat and improve safety.

[0119] In summary, the positioning groove is circular or rectangular, which can ensure the stable placement of the cylindrical battery cell 13 and the rectangular battery cell 13, improve the adaptability of the placement of battery cells 13 of different shapes, and has good practicality.

[0120] In some embodiments, the battery cell 13 includes one of a cylindrical battery cell and a sheet-shaped battery cell.

[0121] In this way, by providing battery cells 13 of different shapes, the actual needs of users can be met.

[0122] Specifically, in one embodiment, the battery cell 13 includes one of a cylindrical battery cell and a sheet battery cell, that is, the energy storage power supply 10 can work with a cylindrical battery cell or a sheet battery cell to ensure the user's power demand, and no specific restrictions are made here.

[0123] In one embodiment, the battery cell 13 may be a cylindrical battery cell, such as Figure 1 As shown, it can be matched and placed in a housing 11 provided with a plurality of cylindrical positioning parts 111, thereby ensuring the charging and discharging process of the energy storage power supply 10.

[0124] In another embodiment, the battery cell 13 may be a sheet-shaped battery cell (not shown), which can be placed in the housing 11 having a plurality of rectangular positioning portions 111, thereby ensuring the charging and discharging process of the energy storage power supply 10. The sheet-shaped battery cell may be formed by stacking multiple battery cells 13 on their sides.

[0125] For example, the sheet-shaped battery cell can be a soft-pack battery cell made of aluminum-plastic film or steel-plastic film, which has the advantages of small size and high energy density of a single battery cell 13. At the same time, in the event of a safety hazard, the shell of the soft-pack battery cell can also release internal stress in the form of bulging or cracking, thereby improving the safety of the soft-pack battery cell. Figure 5 、 Figure 8 and Figure 9 As shown, the width of the soft-pack battery cells can match the width of the positioning portion 111 (e.g., left-right direction), and they can be stacked and arranged along the length direction (e.g., front-back direction). Of course, the width of the soft-pack battery cells can also be approximately half the width of the positioning portion 111, so that two rows of soft-pack battery cells can be placed side by side in the positioning portion 111, while leaving a gap to accommodate the colloid to ensure that the soft-pack battery cells are stably fixed.

[0126] See also Figure 12 In some embodiments, the battery cell 13 includes two electrodes 133 , and the two electrodes 133 are located at the second end 132 of the battery cell 13 .

[0127] In this way, the structure of the energy storage power supply 10 can be simplified, the welding space can be reduced, and miniaturization is facilitated.

[0128] Specifically, in one embodiment, Figure 1 and Figure 12 As shown, the battery cell 13 includes a first end 131 and a second end 132 . The first end 131 and the second end 132 are arranged opposite to each other and are stably connected by the positioning portion 111 and the fixing member 15 respectively, thereby ensuring safe operation of the battery cell 13 .

[0129] In one embodiment, the battery cell 13 includes two electrodes 133, which are located at the second end 132 of the battery cell 13, that is, the first end 131 can be an end without the electrode 133, which can be connected to the positioning portion 111, and the second end 132 can be an end with two electrodes 133, which can be connected to the fixing member 15, the electrical connector 17 and the collection board 19 to ensure the input or output of power.

[0130] In one embodiment, Figure 1 and Figure 12 As shown, the two electrodes 133 may include a first electrode 1331 and a second electrode 1332, wherein the first electrode 1331 may be a positive electrode and the second electrode 1332 may be a negative electrode, to form a positive and negative interface of the battery cell 13 to ensure charging or discharging of the battery cell 13. Of course, the first electrode 1331 may also be a negative electrode and the second electrode 1332 may also be a positive electrode, and no specific limitation is made here.

[0131] That is, in one embodiment, one of the two electrodes 133 is a positive electrode, and the other is a negative electrode.

[0132] In this way, it is ensured that the same side of the battery cell 13 can realize the charging function or the discharging function, reducing the winding and welding steps, which is conducive to improving the miniaturization of the energy storage power supply 10.

[0133] It can be understood that the two electrodes 133 are located at the second end 132 of the battery cell 13, that is, the two electrodes 133 are located on the same side of the battery cell 13, which can reduce the arrangement of electrical connectors 17 and collection boards 19 at the first end 131, reduce welding steps, save installation space, reduce costs, and facilitate the miniaturization design of the energy storage power supply 10, which has good practicality.

[0134] In other embodiments, the first end 131 may be an end provided with two electrodes 133 , and the second end 132 may be an end not provided with electrodes 133 , to ensure that the energy storage power supply 10 operates normally, which is not specifically limited here.

[0135] In some embodiments, the two electrodes 133 are two protrusions of different shapes or sizes.

[0136] In this way, it is convenient to distinguish the positive and negative poles of the battery cell 13 according to the shape or size of the protrusion, thereby improving the accuracy of the installation and connection of the battery cell 13 and ensuring the safe use of the energy storage power supply 10.

[0137] Specifically, in one embodiment, the two electrodes 133 are two protrusions of different shapes or sizes, so that the two electrodes 133 are easy to distinguish, ensuring the correct wiring of the battery cells 13, thereby meeting the user's power supply needs for series battery cells 13 or parallel battery cells 13.

[0138] It can be understood that the boss can be Figure 12 There are two first poles 1331 and second poles 1332 of different shapes and electrical properties, wherein the protrusions can be circular and elliptical, so as to distinguish the wiring and ensure safe use.

[0139] That is, the circular protrusion can be the positive electrode and the elliptical protrusion can be the negative electrode, or the circular protrusion can be the negative electrode and the elliptical protrusion can be the negative electrode. Of course, the protrusion can also be of other shapes, which is not specifically limited here.

[0140] In some embodiments, a protrusion is provided at the second end 132 of the battery cell 13 , and the protrusion serves as one of the two electrodes 133 , and the other portion of the second end 132 of the battery cell 13 serves as the other of the two electrodes 133 .

[0141] In this way, the battery cell 13 can realize charging input and discharging output at the second end 132 , thereby ensuring the normal operation of the energy storage power supply 10 .

[0142] Specifically, in one embodiment, the second end 132 of the battery cell 13 is provided with a protrusion, so that the protrusion can serve as an electrode 133 , that is, as a terminal of the battery cell 13 .

[0143] In one embodiment, the other part of the second end 132 of the battery cell 13 can become the other of the two electrodes 133, that is, in addition to the area occupied by the boss, another electrode 133 can be formed in the other part of the second end 132. For example, by setting another boss or other form on the other part of the second end 132 to form another terminal of the battery cell 13, it is ensured that the battery cell 13 can realize the functions of charging input and discharging output at the second end 132, while reducing the welding space for setting the battery cell 13 at both ends, which is practical.

[0144] See also Figure 1 In some embodiments, the fixing member 15 includes a split bracket 151, which is formed with a plurality of second positioning portions (not shown), the second positioning portions are used to fix the second end 132, and the second positioning portions are provided with a through hole 1511 for the protrusion to extend.

[0145] In this way, the second end 132 of the battery cell 13 is stably placed, thereby ensuring the overall stability of the battery cell 13 .

[0146] Specifically, in one embodiment, Figure 1As shown, the split bracket 151 can be a detachable bracket, which can be set at the second end 132 of the battery cell 13 and fixed to the shell 11 by screws 152 to ensure that the battery cell 13 is stably set inside the energy storage power supply 10.

[0147] It is understandable that Figure 1 As shown, the split bracket 151 may be provided with screws 152 , and the housing 11 may be provided with corresponding threaded screw holes, so that the split bracket 151 and the housing 11 can be detachably connected, thereby ensuring the assembly, maintenance and replacement of the battery cell 13 .

[0148] In one embodiment, the split bracket 151 is formed with multiple second positioning portions (not shown), and the second positioning portions can be blind holes that match the shape and size of the second end 132 of the battery cell 13, and can form an interference fit to fix the second end 132 of the battery cell 13 on the split bracket 151.

[0149] In one embodiment, the split bracket 151 is formed with a plurality of through holes 1511, and the diameter of the through holes 1511 is smaller than the diameter of the second end 132 of the battery cell 13 and can be arranged concentrically with the second positioning portion (not shown), so that the second end 132 of the battery cell 13 abuts the second positioning portion, that is, the split bracket 151 abuts the periphery of the through holes 1511, thereby securing the second end 132 of the battery cell 13. Furthermore, because the first end 131 of the battery cell 13 is secured by the positioning portion 111, the battery cell 13 is stably secured within the energy storage power supply 10.

[0150] In addition, the two electrodes 133 are located at the second end 132 of the battery cell 13, so that the two electrodes 133 can be protruded through the through hole 1511 to be welded to the electrical connector 17, so that the battery cell 13 is electrically connected to the electrical connector 17, thereby ensuring the normal charging and discharging process of the battery cell 13.

[0151] In one embodiment, the through hole 1511 may be a cylindrical hole or a hole of other shapes to ensure that the second end 132 of the battery cell 13 abuts against the split bracket 151 and is fixed at the position of the through hole 1511, which is not specifically limited here.

[0152] In some embodiments, the fixing member 15 includes a fixing gel.

[0153] In this way, the battery cell 13 is stably placed in the energy storage power supply 10 , thereby ensuring the safe operation of the battery cell 13 .

[0154] Specifically, the fixing member 15 includes a fixing colloid. That is, when the first end 131 of the battery cell 13 is fixed to the positioning portion 111 , the fixing colloid can stably connect the battery cell 13 as a whole to the energy storage power supply 10 to ensure safe operation of the battery cell 13 .

[0155] It can be understood that in one embodiment, when the first end 131 of at least one battery cell 13 is inserted into the positioning portion 111, the positioning portion 111 arranges the battery cells 13 in an array. It is only necessary to inject a fixing colloid into the accommodating cavity 112 of the shell 11 and guide it to the gaps between the multiple battery cells 13, thereby ensuring that the second ends 132 of the multiple battery cells 13 are also stably connected to the energy storage power supply 10, thereby ensuring the overall stable arrangement of the battery cells 13 and ensuring the safe operation of the battery cells 13.

[0156] In one embodiment, the fixing colloid may be a structural adhesive.

[0157] On the one hand, structural adhesive can withstand significant loads. By injecting structural adhesive into the gaps between the multiple battery cells 13, the cells' 13 impact resistance can be enhanced. If the housing 11 of the energy storage power supply 10 is damaged and directly impacts the battery cells 13, the structural adhesive can absorb some of the impact force while also transferring it to the entire battery cell 13, mitigating damage.

[0158] On the other hand, the structural adhesive has good corrosion resistance. When some battery cells 13 leak electrolyte due to structural damage or the explosion-proof valve (not shown) of the battery cell 13 sprays electrolyte due to thermal runaway, the structural adhesive can prevent further leakage of electrolyte and corrosion of other battery cells 13 or other structural components.

[0159] In addition, the structural adhesive can also have good thermal conductivity, thereby transferring the heat generated by the battery core 13 to the positioning portion 111 and the housing 11, which is beneficial to reducing the operating temperature of the battery core 13 and thus ensuring the safe operation of the battery core 13.

[0160] See also Figure 13 In some embodiments, the housing 11 includes a first shell 117 and a second shell 119 , the first shell 117 is detachably connected to the second shell 119 , and the positioning portion 111 is provided on the first shell 117 or the second shell 119 .

[0161] This makes assembly or maintenance easier and more practical.

[0162] Specifically, in one embodiment, Figure 13 As shown, the shell 11 includes a first shell 117 and a second shell 119, wherein the first shell 117 can be a lower shell and the second shell 119 can be an upper shell, and the first shell 117 and the second shell 119 are arranged opposite to each other and can be matched and connected by means of threads, snaps or clamps to provide a relatively stable and sealed environment, thereby ensuring that the battery cell 13 operates safely and stably in the energy storage power supply 10.

[0163] In some embodiments, the first shell 117 and the second shell 119 may also be located at the front and rear parts or the left and right parts of the housing 11 respectively, or the first shell 117 and the second shell 119 may be distributed at two diagonal corners of the housing 11 .

[0164] It is understood that the first shell 117 and the second shell 119 can be detachably connected to each other by means of threads, buckles, or clamps. The first shell 117 and the second shell 119 enclose the accommodating cavity 112 and accommodate the battery cell 13. This can increase the convenience of assembly or disassembly maintenance.

[0165] In one embodiment, the positioning portion 111 is provided on the first shell 117 or the second shell 119. It will be appreciated that when the first shell 117 is the lower shell, the positioning portion 111 is provided on the first shell 117 to secure and support the battery cell 13. When the second shell 119 is the lower shell, the positioning portion 111 is provided on the second shell 119 to secure and support the battery cell 13. When the shell 11 is placed on its side, the positioning portion 111 can be provided on either the first shell 117 or the second shell 119, both ensuring securement and support of the battery cell 13, thereby ensuring proper operation of the battery cell 13.

[0166] Also, see Figure 13 In some embodiments, the energy storage power supply 10 may further include an inverter 21 , a battery management system 23 , and a mainboard 25 disposed in the housing 11 , and a front panel 27 disposed outside the housing 11 .

[0167] The inverter 21 is disposed on the battery cell 13 and can be electrically connected to the battery cell 13 to convert the direct current generated by the battery cell 13 into alternating current for use by electrical devices.

[0168] The battery management system 23 is arranged between the battery cell 13 and the inverter 21, and can be used to monitor the status information of the battery cell 13, such as current, temperature or voltage, to avoid overcharging, overdischarging or short circuit of the battery cell 13, so as to protect the battery cell 13 from damage.

[0169] The mainboard 25 can be electrically connected to the battery cells 13 and the inverter 21 , and can obtain user instructions and control the charging or discharging process of the battery cells 13 and the inverter 21 through the user input port.

[0170] The front panel 27 is electrically connected to the mainboard 25 and can display information such as the current charge level and battery temperature of the energy storage power supply 10. The front panel 27 can also include a port for connecting the energy storage power supply 10 to a power-consuming device or a charging device, allowing the battery cells 13 to supply power to the power-consuming device or charge the charging device.

[0171] In one embodiment, the energy storage power supply 10 may further include a handle 29 and a foot pad 31 .

[0172] The handle 29 is U-shaped and connected to the second shell 119. The handle 29 can be folded and stored in a groove formed in the second shell 119, so that the energy storage power supply 10 is convenient to lift and place, which is labor-saving and practical.

[0173] In one example, the handle 29 can be integrally formed of a hollow aluminum material to reduce the weight of the energy storage power supply 10 while ensuring supporting strength.

[0174] In one embodiment, there may be multiple foot pads 31 disposed at the bottom of the first shell 117 , which may be used to increase the friction at the bottom of the energy storage power supply 10 , thereby preventing the energy storage power supply 10 from accidentally sliding, colliding, or falling, and improving the safety of the energy storage power supply 10 .

[0175] In one example, the material of the foot pad 31 can be plastic, which can reduce costs while ensuring friction.

[0176] See also Figure 1 In some embodiments, the positioning portion 111 and the housing 11 are integrally formed.

[0177] In this way, the continuity and structural strength of the positioning portion 111 and the housing 11 are improved, thereby ensuring the safety and stability of the energy storage power supply 10.

[0178] Specifically, in one embodiment, the positioning portion 111 and the shell 11 are integrally formed, which can improve the connection stability between the positioning portion 111 and the shell 11, so that the shell 11 has better supporting strength, thereby ensuring that the positioning portion 111 is stably connected to the first end 131 of the battery cell 13, thereby ensuring the safety of the battery cell 13.

[0179] In one embodiment, the positioning portion 111 and the shell 11 can be integrally formed by an injection molding process, or by other processes to ensure that the positioning portion 111 and the shell 11 are an integrally formed part, thereby reducing the use and layout space of the bracket, and no specific restrictions are made here.
