[0002] In energy storage systems, equipotential bonding is a crucial measure to ensure the safety of high-voltage systems. Inside energy storage containers, to ensure safety, the outer casings of all battery packs must be equipotentially bonded and uniformly grounded.

[0003] In related technologies, the equipotential bonding between the energy storage battery pack and the container structure relies on equipotential bonding harnesses, with the container grounded. However, when configuring numerous energy storage battery packs in an energy storage container, not only are a large number of equipotential bonding harnesses required, but the installation of these harnesses must also be done manually by employees, resulting in a huge workload. Furthermore, to ensure the precise layout of the equipotential bonding harnesses within the battery compartment, employees must constantly adjust the routing of the harnesses, making the operation complex and tedious.

[0036] This utility model proposes an energy storage battery pack installation structure 100.

[0037] Please see Figures 1 to 4 In one embodiment of the present invention, the energy storage battery pack mounting structure 100 includes a mounting bracket 1, a battery pack 2, and an equipotential bonding member 3. The mounting bracket 1 is grounded; the battery pack 2 is slidably mounted on the mounting bracket 1; the equipotential bonding member 3 connects the battery pack 2 and the mounting bracket 1 and restricts the sliding of the battery pack 2 on the mounting bracket 1.

[0038] In this embodiment, the mounting bracket 1, the outer shell of the battery pack 2, and the equipotential bonding member 3 are all made of conductive metal material. The mounting bracket 1 is used to support the battery pack 2. In order to reduce its weight and facilitate the operation of the battery pack 2 inside the mounting bracket 1, the mounting bracket 1 in this embodiment preferably adopts a frame structure. The mounting bracket 1 includes two sets of racks, each set of racks includes multiple vertical rods, and one or more horizontal rods are set to connect the vertical rods. The two sets of racks are arranged opposite each other, and the horizontal rods on each set of racks correspond to the horizontal rods on the other set of racks. The two sides of the battery pack 2 are respectively mounted on a horizontal rod. In this way, the obstruction of the battery pack 2 by the mounting bracket 1 is reduced, and the mounting bracket 1 is avoided from affecting the wiring or adjustment of the battery pack 2.

[0039] Battery pack 2 is placed on the surface of the crossbar of mounting bracket 1 and can slide relative to the surface of the crossbar to adjust the installation position or density of battery pack 2. Multiple installation spaces can be provided on mounting bracket 1 to allow battery pack 2 to be layered on the same mounting bracket 1, improving the capacity and space utilization of mounting bracket 1. After adjusting the position of each battery pack 2, it is necessary to fix the battery pack 2 to the mounting bracket 1 and connect each battery pack 2 to the equipotential bonding. By setting the equipotential bonding member 3, each battery pack 2 is connected to the mounting bracket 1 at the same potential, and the mounting bracket 1 is grounded, ensuring the safe operation of each battery pack 2.

[0040] In this embodiment, the energy storage battery connects the battery pack 2 and the mounting bracket 1 via an equipotential bonding member 3. This allows multiple battery packs 2 mounted on the mounting bracket 1 to achieve equipotential bonding. Furthermore, the equipotential bonding member 3 also secures the battery pack 2 to the mounting bracket 1, saving on the need for a separate fixing structure between the battery pack 2 and the mounting bracket 1. This allows for simultaneous installation and fixing of multiple battery packs 2, simplifying the equipotential bonding and fixing steps between the battery pack 2 and the mounting bracket 1, and improving the installation efficiency of the battery pack 2.

[0041] Further, please refer to Figure 4 , Figure 8 and Figure 9 In one embodiment of this utility model, the mounting bracket 1 is provided with a first connecting hole 1a, the battery pack 2 is provided with a second connecting hole 2a, and the equipotential bonding member 3 is provided with a third connecting hole 3a and a fourth connecting hole 3b; the energy storage battery pack mounting structure 100 also includes a first conductive bolt 41 and a second conductive bolt 42. The first conductive bolt 41 passes through the third connecting hole 3a and the first connecting hole 1a in sequence and connects the equipotential bonding member 3 and the mounting bracket 1. The second conductive bolt 42 passes through the fourth connecting hole 3b and the second connecting hole 2a in sequence and connects the equipotential bonding member 3 and the battery pack 2.

[0042] In this embodiment, the equipotential bonding member 3 is a metal plate structure. The equipotential bonding member 3 has a third connection hole 3a and a fourth connection hole 3b. The mounting bracket 1 has a first connection hole 1a. The inner wall of the first connection hole 1a is threaded. The first conductive bolt 41 passes through the third connection hole 3a and is screwed to the inner wall of the first connection hole 1a. The outer shell of the battery pack 2 has a second connection hole 2a. The inner wall of the second connection hole 2a is threaded. The second conductive bolt 42 passes through the fourth connection hole 3b and is screwed to the inner wall of the second connection hole 2a.

[0043] Furthermore, in one embodiment of the present invention, the surface of the mounting bracket 1 is provided with an anti-corrosion paint layer, the periphery of the first connecting hole 1a is provided with a conductive paint layer, the anti-corrosion paint layer is connected to the conductive paint layer and surrounds the periphery of the conductive paint layer; and / or, the surface of the equipotential connector 3 is provided with an anti-corrosion paint layer, the periphery of the third connecting hole 3a and the periphery of the fourth connecting hole 3b are provided with conductive paint layers, the anti-corrosion paint layer is connected to the conductive paint layer and surrounds the periphery of the conductive paint layer.

[0044] In this embodiment, considering that the battery pack 2 in the energy storage container experiences alternating heating and cooling during charging and discharging, resulting in significant condensation during temperature changes, and that direct contact between this condensation and the mounting bracket 1 can easily corrode the bracket, an anti-corrosion paint layer is applied to the surface of the mounting bracket 1 to improve its corrosion resistance. Since the first connecting hole 1a, the third connecting hole 3a, and the fourth connecting hole 3b need to maintain good conductivity to achieve equipotential bonding between the battery pack 2 and the mounting bracket 1, a conductive paint layer is applied around the periphery of these holes. During production, the mounting bracket 1 can be entirely coated with anti-corrosion paint, and then the anti-corrosion paint around the periphery of the first connecting hole 1a, the third connecting hole 3a, and the fourth connecting hole 3b can be polished and coated with conductive paint, which also provides anti-corrosion protection. The nuts of the first conductive bolt 41 and the second conductive bolt 42 may be provided with flange faces to ensure good contact between the nuts and the conductive paint layer. The mounting bracket 1 and the energy storage container can be connected by welding. Attention should be paid to the control of the welding process and the selection of solder to ensure the conductivity of the weld.

[0045] Further, please refer to Figure 8 In one embodiment of this utility model, a conductive spring piece 21 is provided around the periphery of the second connecting hole 2a, and the conductive spring piece 21 elastically abuts against the equipotential bonding member 3. In this embodiment, the conductive spring piece 21 is fixedly disposed around the periphery of the second connecting hole 2a and electrically connected to the outer shell of the battery pack 2. The second conductive bolt 42 is tightened to make the equipotential bonding member 3 abut against the periphery of the second connecting hole 2a, at which time the conductive spring piece 21 elastically abuts against the equipotential bonding member 3. When the second conductive bolt 42 loosens, because the conductive spring piece 21 itself is elastic, the second conductive spring piece 21 can compensate for the loosening distance through elastic deformation, ensuring a stable connection between the equipotential bonding member 3 and the battery pack 2.

[0046] Further, please refer to Figure 9 In one embodiment of this utility model, the third connecting hole 3a is an oblong hole; or, the fourth connecting hole 3b is an oblong hole.

[0047] In this embodiment, considering that the mounting bracket 1 and the like may have dimensional deviations during production or assembly, in order to improve the adaptability of the equipotential bonding member 3 to meet the installation needs when there are dimensional deviations, the third connecting hole 3a or the fourth connecting hole 3b is set as an elongated hole, so that when the first conductive bolt 41 or the second conductive bolt 42 passes through the third connecting hole 3a or the fourth connecting hole 3b, it has a certain degree of adjustability, thereby improving the practicality of the equipotential bonding member 3.

[0048] Further, please refer to Figures 5 to 7In one embodiment of the present invention, the battery pack 2 has a base plate 22, and the mounting bracket 1 is provided with a slide rail 11, on which a groove 11a is formed; the base plate 22 extends into the groove 11a and is slidably connected to the inner wall of the groove 11a.

[0049] In this embodiment, the battery pack 2 includes a base plate 22 and an upper cover. The base plate 22 is connected to the upper cover by bolts and encloses the internal components of the battery within the upper cover. When the battery pack 2 is fixed to the mounting bracket 1, it serves to support the internal components of the battery and the upper cover. The crossbar of the mounting bracket 1 has a groove 11a to serve as a slide rail 11 to guide the directional sliding of the battery pack 2. The base plate 22 protrudes from the upper cover and extends into the groove 11a, slidingly connecting with the inner wall of the groove 11a. This restricts the sliding direction of the battery pack 2 on the mounting bracket 1, simplifies the installation and position adjustment of the battery pack 2, and facilitates the rapid installation and positioning of the battery pack 2 on the mounting bracket 1.

[0050] Further, please refer to Figures 5 to 7 In one embodiment of the present invention, an elastic protrusion 221 is provided on the base plate 22; a limiting rib 12 is provided on the bottom wall of the slide groove 11a, and a limiting groove 12a is formed between the limiting rib 12 and the side wall of the slide groove 11a. The base plate 22 and the elastic protrusion 221 are located in the limiting groove 12a, and the elastic protrusion 221 and the limiting rib 12 are elastically abutted.

[0051] In this embodiment, the elastic protrusion 221 is a metal spring structure and is fixedly mounted on the base plate 22. The groove opening of the slide 11a faces the side wall of the battery pack 2. The bottom wall of the slide 11a is provided with a limiting rib 12, which is spaced apart from the side wall of the slide 11a. A limiting groove 12a is formed between the limiting rib 12 and the side wall of the slide 11a. The width of the limiting groove 12a is slightly less than the sum of the thickness of the elastic protrusion 221 and the base plate 22. When the elastic protrusion 221 is pushed into the limiting groove 12a, the elastic protrusion 221 undergoes elastic deformation and presses against the limiting rib 12. The friction between the elastic protrusion 221 and the limiting rib 12 is sufficient to prevent the battery pack 2 from sliding freely, thus temporarily limiting the battery pack 2 and facilitating the installer to connect and fix the equipotential bonding member 3, the battery pack 2, and the mounting bracket 1.

[0052] Further, please refer to Figure 5 In one embodiment of this utility model, the two ends of the limiting rib 12 are bent away from the limiting groove 12a.

[0053] In this embodiment, in order to reduce the jamming or obstruction when pushing the elastic protrusion 221 into the limiting groove 12a, the two ends of the limiting rib 12 are bent away from the limiting groove 12a. Before the elastic protrusion 221 is fully inserted into the limiting groove 12a, the deformation of the elastic protrusion 221 by the bent surface is guided in advance, and the amount of elastic deformation required for the elastic protrusion 221 to enter the limiting groove 12a is evenly distributed to avoid jamming or obstruction.

[0054] Furthermore, in one embodiment of this utility model, the energy storage battery pack mounting structure 100 includes multiple battery packs 2 and multiple equipotential bonding members 3. Each battery pack 2 is fixed to the mounting bracket 1 through an equipotential bonding member 3. In this embodiment, multiple layers or rows of battery packs 2 can be arranged on the mounting bracket 1, and each battery pack 2 is connected to the mounting bracket 1 through an equipotential bonding member 3, thereby achieving equipotential connection of multiple battery packs 2 on the same mounting bracket 1.

[0055] This utility model also proposes an energy storage container, which includes a container body and an energy storage battery pack mounting structure 100 as described in any of the above embodiments. Mounting brackets 1 are disposed inside the container body and connected to it, and the container body is grounded. Since this energy storage container adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here. Multiple mounting brackets 1 can be disposed inside the container body, each mounting bracket 1 being connected to the container body. Finally, through the grounding of the container body, equipotential bonding of the multiple mounting brackets 1 is achieved.

[0056] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
