[0037] It can be seen that the embodiment of the present application replaces the complex guiding parts in the existing solution by designing an integrated stamping guide structure, thereby realizing the guiding and positioning function between the base, battery pack, and main control box; by designing an integrated stacking connector, the electrical connection between the base, battery pack, and main control box is realized, and the design of the electrical connection circuit is further simplified; thereby achieving the technical effect of improving the utilization rate of the installation space and saving production and installation costs.

[0038] In addition, since the present application adopts a modular design and does not limit the number of battery packs, different numbers of battery packs can be stacked to form an energy storage system that meets different power requirements. Especially in the field of household energy storage, it is conducive to assembly and disassembly, and can flexibly meet the electricity needs of different households. It has high economy and practical value.

[0039] Further, refer to Figure 3 and Figure 4 As shown, Figure 3 This is a schematic diagram of the battery pack structure from an upward perspective.

[0040] It can be understood that the battery pack (or battery PACK) described in the present application includes a box body, a battery module and an electrical connection structure located inside the box body; that is, the box body of the battery pack and the box cover of the battery pack cooperate with each other to form a closed space for accommodating multiple groups of battery modules. The main control box is used to control the output of the battery pack, and the main control box is also provided with a corresponding control connection structure; it should be noted that the internal electrical connection of the battery pack and the main control box is not an improvement point of the present application, and can be set and adjusted by relevant technicians in this field.

[0041] Specifically in this embodiment, a first guide portion 9 is provided at the bottom of the box body of each battery pack 2, and a second guide portion 11 is provided at the top of the box cover of each battery pack 2; preferably, the first guide portion 9 is a guide groove, and the second guide portion 11 is a guide protrusion, so that the guide groove at the bottom of the box body of one battery pack can cooperate with the guide protrusion at the top of the box cover of another battery pack located below it, so that the above-mentioned guide groove and the guide protrusion constitute a set of guide structures between two adjacent battery packs 2. Of course, the first guide portion 9 can also be set as a guide protrusion, and the second guide portion 11 can be set as a guide groove, which is not limited here.

Figure 3 and Figure 5 It can be seen that the four guide columns on the top of the base 1 can cooperate with the guide grooves of the battery pack 2 located above it, thereby forming a set of guide structures between the base 1 and the battery pack 2.

[0044] Furthermore, if Figure 6 As shown, Figure 6 It is a structural schematic diagram of the main control box when viewed from an upward perspective; a fourth guide portion 12 is provided at the bottom of the main control box 3, and the fourth guide portion 12 of the main control box 3 can cooperate with the second guide portion 11 of the battery pack 2 located therebelow to form a guide structure between the main control box 3 and the battery pack 2.

[0045] Preferably, the fourth guide portion 12 is a guide groove, so that Figure 4 and Figure 6 It can be seen that the guide grooves at the bottom of the main control box 3 can cooperate with the guide protrusions at the top of the box cover of the battery pack 2 located therebelow, thereby forming a set of guide structures between the main control box 3 and the battery pack 2.

[0046] Furthermore, in the embodiment of the present application, the first guide portion 9, the second guide portion 11, the third guide portion 8, and the fourth guide portion 12 are all integrally stamped structures.

[0047] Preferably, the top of the base 1 is formed with a plurality of guide columns by an integrated stamping process, the bottom of the box of the battery pack 2 is formed with a groove by an integrated stamping process, the top of the box cover of the battery pack 2 is formed with a bulge by an integrated stamping process, and the bottom of the box of the main control box 3 is formed with a groove by an integrated stamping process. The above-mentioned integrated stamping structure can replace the more complicated external guide parts in the existing solution, reduce the layout space between the various box structures, and save the production and installation costs of the guide parts.

[0048] Of course, the above descriptions of the first guide portion 9, the second guide portion 11, the third guide portion 8 and the fourth guide portion 12 cannot be understood as limitations on the present application.

The male connector 6 of the battery pack 2 corresponds to the position of the female connector 7 of the battery pack 2. Figure 1 and Figure 2 As shown, in two adjacent battery packs 2 , the female connector 7 of one battery pack can be plugged into the male connector 6 of another battery pack located below it to achieve electrical connection between the two adjacent battery packs 2 .

[0050] Specifically, the bottom of the battery pack 2 is reserved for the installation position of the female connector 7, and the top of the battery pack 2 is reserved for the installation position of the male connector 6. The male connector 6 and the male connector 7 of each battery pack are connected to the internal electrical circuit, and at the same time, the battery pack is connected to the internal electrical circuit of the battery pack. Figure 1 As shown, taking the second battery pack from bottom to top as an example, the male connector 6 of the battery pack can be electrically connected to the female connector 7 of the battery pack above it, and the female connector 7 of the battery pack can be electrically connected to the male connector 6 of the battery pack below it, thereby achieving electrical connection between multiple stacked battery packs 2.

[0051] Of course, a male connector can also be set at the bottom of the battery pack box and a female connector can be set at the top of the battery pack box. In this case, it is necessary to make corresponding adjustments to the connector types on the base and the main control box, such as setting a female connector on the base and a male connector on the main control box. This will not be elaborated here.

[0052] Furthermore, combined with Figure 1 , Figure 3 and Figure 5 As shown, a male connector 6 is provided on the top of the base 1, and the male connector 6 of the base 1 corresponds to the position of the female connector 7 of the battery pack 2 located above it to achieve electrical connection between the base 1 and the battery pack 2.

[0054] It can be understood that in the embodiment of the present application, a connection circuit is provided inside the male connector 6 and the female connector 7, and an electrical circuit can be formed between the base 1, the battery pack 2, and the main control box 3 during the stacking and assembly process, thereby making it unnecessary to install external cables for the household battery cabinet, thereby reducing the production and installation costs of the cables.

[0055] Preferably, combined Figures 1 to 6As shown, the battery cabinet further includes a fixing plate 4, and one side of the base 1, the battery pack 2 and the main control box 3 are provided with fixing plate mounting screw holes 13, which are used to cooperate with the fixing plate 4 to strengthen the fixation between the boxes. The fixing plate 4 is respectively installed at the connection position between the base 1 and the battery pack 2, the connection position between two adjacent battery packs 2, and the connection position between the battery pack 2 and the main control box 3.

[0056] Furthermore, the main control box 3 is provided with an output terminal 16 and a communication terminal 17 on the outside, and the battery pack 2 is provided with a box handle 5 on the outside. Figure 1 and Figure 2 As shown, the box handle 3 can be respectively arranged on the front and rear sides of the battery pack 2; Figure 3 and Figure 4 As shown, a pressure relief valve 18 is also provided on one side of the battery pack 2.
