[0037] First, some nouns involved in this application are analyzed:

[0038] Energy storage container: used for storing renewable energy, capable of storing electricity generated by renewable energy such as solar energy and wind energy, providing power support when needed, and achieving stable output of electricity. The energy storage container includes central control cabinet, multiple cluster racks, fire fighting equipment, air conditioners, multiple high-voltage boxes and multiple battery modules. Among them, multiple can be greater than or equal to 2, and the number of equipment varies according to different projects.

[0039] In the related art, the grounding method of the battery auxiliary device in the energy storage container is that after the container body is grounded, the battery auxiliary device is connected to the container body by screws to achieve the grounding effect, but the contact area of ​​the screw connection is small and the grounding effect is not good. For example, a first threaded hole is provided at the bottom of the cluster frame, and a first stud is installed at the bottom of the container body. The first threaded hole and the first stud are fixed by a nut to achieve the fixing and grounding effect. However, since the first stud and the first threaded hole are only in contact through the screw thread, the contact area is small and the grounding effect is not good. After the first stud is rusted, the grounding effect will be worse, the reliability of the connection cannot be guaranteed, and it is easy to cause the risk of disconnection, which poses a serious safety hazard.

[0040] Based on this, an energy storage container grounding device is provided in an embodiment of the present application, which is specifically described through the following embodiments.

[0041] Figure 1 is a schematic diagram of the structure of the energy storage container grounding device provided in the embodiment of the present application, such as Figure 1 As shown, the energy storage container grounding device provided in the embodiment of the present application includes an energy storage container 10 and a first grounding member 20. The first grounding member 20 may be a grounding copper busbar.

[0042] The energy storage container 10 includes:

[0043] The container body 110 has a first fixing member 130 installed at the bottom thereof. The first fixing member 130 is electrically connected to a first end of a first grounding wire 1301. The container body 110 is electrically connected to a first grounding member 20. The first grounding member 20 is connected to the ground through a conductive metal. The first fixing member 130 is grounded through the first grounding member 20.

[0044] The battery auxiliary device 120 is connected to the second end of the first grounding wire 1301 and is grounded through the first grounding wire 1301. The first end of the first grounding wire and the second end of the first grounding wire are both cold-pressed terminals. The fixing member mentioned below can be a stud or a screw, and the fixing hole can be a threaded hole. The battery pack auxiliary device refers to a battery module 160 (see FIG. 1 ) used to support and assist the battery module 160 in the energy storage container 10. Figure 2 ) Equipment that operates normally, such as central control cabinets, cluster racks and fire protection equipment.

[0045] Specifically, a grounding stud is welded on the outer side of the container body 110, and after the threaded hole on the first grounding piece 20 passes through the grounding stud, it is fixed to the outer side of the container body 110 by a nut. The first grounding piece 20 is then connected to the ground through a conductive metal, so that the container body 110 is connected to the ground to achieve a grounding effect. In this embodiment, the first grounding piece 20 is connected to the ground through a conductive metal instead of being connected to the ground through a grounding wire, which can better improve the conductivity. In one example, the conductive metal can be a copper rod, one end of which is connected to the first grounding piece 20, and the other end of the copper rod is connected to the ground. Specifically, a hole is provided at one end of the copper rod, and a screw passes through the holes of the first grounding piece 20 and one end of the copper rod, and is fixed by a nut, and the other end of the copper rod is knocked into the ground.

The battery auxiliary device 120 is connected to the cold-pressed terminal at the second end of the first grounding wire 1301 and is fixed by a nut, so that the battery auxiliary device 120 is electrically connected to the container body 110, and the container body 110 is connected to the ground, thereby achieving grounding of the battery auxiliary device 120.

[0047] Since the contact area of ​​the cold-pressed terminal is larger than that of the screw thread, the grounding effect is better. Even if the first fixing member 130 is rusted, the container body 110 and the cold-pressed terminal can still be normally contacted and connected without causing the risk of disconnection, thus ensuring the reliability of the connection.

[0048] In one example, a plurality of first grounding members 20 are provided, for example, four first grounding members 20 are provided, and the four first grounding members 20 are respectively electrically connected to four grounding studs on the outer side of the container body 110, and are respectively connected to the ground through four conductive metals. By providing a plurality of first grounding members 20, the conductivity of the container body 110 can be further improved, and the grounding effect of the container body 110 can be improved.

The central control cabinet 1202, the cluster frame 1201 and the fire fighting device 1203 are connected to the container body 110, which is the first-level grounding. The air conditioner 170 is connected to the central control cabinet 1202 to achieve electrical grounding, and the high-voltage box 150 and the battery module 160 are connected to the cluster frame 1201, which is the second-level grounding, and finally the energy storage container 10 is fully grounded. Among them, the first level, second level and ultimate mentioned in this embodiment only represent the connection order.

[0074] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
