[0002] Energy storage battery packs are composed of multiple cells connected in series and parallel. The nominal voltage of a single cell ranges from 2.4V to 3.7V. Six mainstream cathode materials are used, with nominal voltages of: lithium cobalt oxide 3.6V; lithium manganese oxide 3.7V; lithium nickel cobalt manganese oxide 3.7V; lithium iron phosphate 3.2V; lithium nickel cobalt aluminum oxide 3.6V; and lithium titanate 2.4V. To achieve nominal voltages of 12V, 24V, 48V, 60V, and 72V, 3 to 24 cells need to be connected in series to meet the voltage requirements; additionally, cells need to be connected in parallel to meet capacity requirements. The electrodes of individual cells are connected in strings using conductive metal sheets welded or bolted together to form a single battery pack, which is then packaged for use.

[0003] Taking a 3.2V lithium iron phosphate cell with a capacity of 100Ah as an example, the weight of a single cell is approximately 2Kg. To assemble a 48V module, 16 cells are needed, weighing 32Kg, with an energy storage capacity of approximately 4.8KWh. Including the casing, the total weight is approximately 50Kg. Larger energy storage capacities will exceed 100Kg.

[0004] Battery cells are connected in series or parallel using wires or other metal conductors and fastened by welding or bolting.

[0005] The battery cell pack has the following shortcomings: there is no uniform standard for the external dimensions of battery cells of the same capacity; battery cells of the same capacity from different manufacturers have different length, width and height dimensions; and energy storage boxes with fixed dimensions are not universal.

By setting a movable electrical connection mechanism on the horizontal slide rail, it can adapt to the width of the battery cell. By moving the horizontal slide rail on the vertical slide rail, it can adapt to the length of the battery cell. By adjusting the electrical connection mechanism, it can adapt to the height of the battery cell. Thus, the box can meet the adjustment in the length, width and height directions when the battery cell is installed, adapt to the differences in battery cell size from different manufacturers, and make the energy storage box universal.

[0007] The objective of this utility model is achieved through the following technical solution:

The lateral slide rails are provided with a plurality of electrical connection mechanisms for connecting the battery cell electrodes, and the electrical connection mechanisms are slidably disposed on the lateral slide rails.

[0010] Furthermore, the two longitudinal slide rails are provided with grooves on opposite sides, and the two ends of the transverse slide rail are provided with slide seats that slide in cooperation with the grooves.

[0011] Furthermore, it also includes a lateral clamping mechanism for fixing or loosening the battery cell laterally.

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] See Figures 1-5 This utility model provides a technical solution: Example

[0031] like Figures 1-5As shown, an energy storage battery box includes a box body 17, two longitudinal slide rails 18 and multiple sets of transverse sliding mechanisms. The two longitudinal slide rails 18 are connected to the box body 17 and are arranged in parallel. The transverse sliding mechanisms are slidably arranged between the two longitudinal slide rails 18.

[0032] like Figures 1-3 As shown, the transverse sliding mechanism includes two transverse slide rails 13, the two ends of which are slidably connected to the two longitudinal slide rails 18 respectively. The transverse slide rails 13 are provided with a plurality of electrical connection mechanisms 20 for connecting the battery cell electrodes 16, and the electrical connection mechanisms 20 are slidably disposed on the transverse slide rails 13.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the electrical connection mechanism includes an insulating base 1, conductive contacts 2 disposed on the insulating base 1, and a driving mechanism, wherein a wire 3 is electrically connected to the conductive contacts 2;

[0034] The drive mechanism is connected to the housing via a seat 15. The drive mechanism is used to drive the conductive contact 2 to move closer to or away from the battery electrode 16. A sliding block 14, T-shaped, is provided on the side of the seat 15 away from the drive mechanism. A sliding groove adapted to the sliding block 14 is provided on the transverse slide rail 13. The seat 15 slides in cooperation with the transverse slide rail 13 via the sliding block 14, the sliding groove, and the transverse slide rail 13. The transverse slide rail 13 is slidably connected to the housing via a vertical slide rail.

[0035] like Figure 1 As shown, the seat cover 15 is provided with a guide sleeve 4; the driving mechanism includes a handle 5, a slider 6 and a connector 7. The handle 5 has an L-shaped structure. One end of the handle 5 is rotatably connected to the lug 9 provided on the seat cover 15 through a rotating shaft. The handle 5 is also hinged to the slider 6 through a connecting rod plate 8. The slider 6 is slidably connected to the guide sleeve 4 (the slider 6 can move along the axial direction of the guide sleeve 4). The slider 6 is connected to the insulating seat 1 through the connector 7.

[0036] It also includes an adjusting screw 10, which is connected to the connector 7 after being screwed into the slider 6 by a thread.

[0037] The insulating base 1 is provided with an upper cover 11, and the connector 7 is connected to the upper cover 11. A spring 12 is provided between the insulating base 1 and the upper cover 11.

[0038] The two longitudinal slide rails 18 are provided with grooves 21 on opposite sides, and the two ends of the transverse slide rail 13 are provided with slide blocks 22 that slide in cooperation with the grooves 21.

[0039] It also includes a lateral clamping mechanism 23, which is used to fix or loosen the battery cell laterally. The lateral clamping mechanism 23 includes a longitudinal rod 24, a drive assembly 25, and a clamping plate 19 disposed on the longitudinal rod 24. The clamping plate 19 is disposed corresponding to the battery cell. The drive assembly 25 is connected to the longitudinal rod 24 and is used to electrically clamp the plate 19 closer to or away from the battery cell via the longitudinal rod 24.

[0040] The drive assembly 25 includes at least two reciprocating linear motion components. In this embodiment, the reciprocating linear motion component is a T-shaped lead screw, but it can also be an electric actuator, a cylinder, etc.

[0041] In this embodiment, the longitudinal slide rail is set along the length of the box; two sets of four transverse slide rails are set. In specific applications, the number of slide rails can be increased or decreased according to the number of battery cells. The transverse slide rails are set along the width of the box.

[0042] Working principle: such as Figure 1 and Figure 2 As shown, (1) Length adjustment: The battery cells are placed side by side into the housing 17, and then the horizontal slide rail 13 is slid along the longitudinal slide rail 18, thereby adjusting the distance between two adjacent horizontal slide rails 13. Since the two connected horizontal slide rails 13 are equipped with an electrical connection mechanism 20, the distance of the electrical connection mechanism 20 is adjusted synchronously when the distance between the horizontal slide rails 13 is adjusted, so as to adapt to battery cells of different lengths and ensure that the conductive contacts of the electrical connection mechanism 20 can be adjusted to always correspond to the battery cell electrodes, ensuring that the two can be electrically connected.

[0043] (2) For example Figure 1 and Figure 2 As shown, width adjustment: After a sufficient number of battery cells are obtained, the cells are fixed by a clamping mechanism to prevent displacement along the cell arrangement direction (cell width direction). The adjustment process is as follows: the reciprocating linear motion component drives the longitudinal rod 24 towards the battery cell. During this process, the clamping plate 19 on the longitudinal rod 24 moves synchronously until the clamping plate 19 presses firmly against the side of the battery cell. At this time, while clamping and fixing the battery cell, appropriate working pressure can be applied to the battery cell. When the battery cell needs to be removed and released, the reciprocating linear motion component moves in the opposite direction, and the longitudinal rod 24 moves downward away from the battery cell to complete the release of the battery cell.

[0044] (3) such as Figure 1 , Figures 3-5 As shown, height adjustment: conductive contact 2 and wire 3 are electrically connected to the cell electrode 16. Through the arrangement of wire 3, series and / or parallel connection between cells can be completed with other cell electrodes 16.

[0045] Rotating the adjusting screw 10 causes it to move up or down, which in turn drives the insulating base 1 and the conductive contact 2 to move up or down synchronously. This allows for adjustment of the distance between the conductive contact 2 and the battery cell electrode 16, adapting to the connection of battery cell electrodes 16 at different heights.

[0046] The process of pressing and locking the conductive contact 2 with the battery electrode 16 is as follows: the handle 5 is pulled, and the handle 5 rotates downward along the lug 9 on the seat 15. Through the hinge of the connecting rod plate 8, the slider 6, connector 7, upper cover 11, insulating seat 1 and conductive contact 2 are pushed. Under the limiting action of the seat 15, the aforementioned components can only move vertically, thereby causing the conductive contact 2 to move downward.

[0047] When the conductive contact 2 contacts the cell electrode 16, the contact insulating seat 1 stops moving. The slider 6 and its connected adjusting screw 10, connector 7, and top cover 11 continue to slide down to compress the spring 12, thereby causing the reaction force of the spring 12 to act on the contact and apply pressure to the conductive contact 2 to ensure that the conductive contact 2 better fits the cell electrode 16 and maintains good contact.

[0048] The entire device is based on a base sleeve as a module, which is connected to the transverse slide rail 13 via the base sleeve. By moving left and right on the transverse slide rail 13, it can accommodate battery cells of different widths.

[0049] This energy storage battery box can also integrate various sensors (such as voltage sensors, current sensors, temperature sensors, etc.) to collect real-time data on cell voltage, current, equipment temperature, charging and discharging status, and real-time stored energy; inverter operating voltage, current, and grid parameters. The collected data is then uploaded to a cloud server via wireless networks such as 4G, 5G, or WiFi, enabling management of individual or clustered devices. Real-time push notifications of device operation data and fault alarms are sent to user apps and PC clients, facilitating remote monitoring and maintenance. When equipment malfunctions, real-time data can be remotely shared and analyzed with technical personnel for remote diagnosis and troubleshooting.

[0050] Meanwhile, all functional components use a modular structure and are all pluggable, which allows ordinary on-site personnel to easily and quickly replace component modules under the guidance of remote professional technicians, perfectly solving problems such as long fault repair time, high cost, and return and transportation of faulty equipment.

[0051] This utility model allows for the installation of a movable electrical connection mechanism on a horizontal slide rail, which can accommodate the width of the battery cell. The horizontal slide rail can move on a vertical slide rail to accommodate the length of the battery cell, and the electrical connection mechanism can be adjusted to accommodate the height of the battery cell. This allows the housing to be adjusted in length, width, and height during battery cell installation, adapting to differences in battery cell sizes from different manufacturers and making the energy storage box universal.

[0052] The spring installed on the electrical connection mechanism generates pressure that can ensure a 200N pressure is applied between the battery cell electrodes and contacts, guaranteeing a reliable electrical connection.

[0053] The lateral clamping mechanism can clamp and release the battery cells. When clamping, it applies the necessary clamping pressure to the battery cell, simultaneously securing it. When releasing, it coordinates with the unlocking and movement of other components to enable the installation and removal of individual cells.

[0054] The combined action of the above mechanisms enables the fixing and unfixing of the battery cell assembly, providing convenience for cell replacement.

[0055] Individual cells can be disassembled, installed, and replaced separately, avoiding the installation and maintenance drawbacks of traditional cell packs that are welded and connected together to form a battery pack.

[0056] During installation, the heavy overall installation mode has been changed to single-cell installation, reducing the number of installers from at least 2-3 to just 1 person for easy installation.

[0057] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
