[0050] The embodiments of the present application will be described in detail with reference to the drawings. However, those skilled in the art can understand that in the embodiments of the present application, many technical details are presented in order to make the reader better understand the present application. However, the technical solutions claimed by the present application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0051] The embodiments of the present application provide a battery device, an energy storage system and an electrical equipment, which at least have the advantages of improving the installation efficiency of workers.

[0052] As shown in Figures 1 to 7 The battery device includes a box body 1 and a mounting assembly. The box body 1 has a communication port and a containing space in communication with each other. The containing space is used to contain a battery assembly. The mounting assembly includes a bearing structure 10, a first cover setting structure 20, a mounting structure 30 and a second cover setting structure 40. The bearing structure 10 is arranged at the communication port. The bearing structure 10 has a high-voltage mounting area 11 and a low-voltage mounting area 12. The first cover setting structure 20 is set at the high-voltage mounting area 11. The first cover setting structure 20 has a containing recess 21 used to contain a high-voltage electrical element arranged at the high-voltage mounting area 11. The mounting structure 30 is arranged at the low-voltage mounting area 12. The mounting structure 30 is used to mount a low-voltage electrical element. The second cover setting structure 40 is set at the low-voltage mounting area 12. The second cover setting structure 40 has a cover setting recess 41. At least part of the cover setting recess 41 is used to contain a low-voltage electrical element. The first cover setting structure 20 is integrally formed with the bearing structure 10.

[0053] According to the technical scheme, the battery device comprises a box body 1 and a mounting assembly. The box body 1 has a communication port and a containing space in communication with each other. The containing space is used for containing a battery assembly. A bearing structure 10 of the mounting assembly is arranged at the communication port. The bearing structure 10 has a high-voltage mounting area 11 and a low-voltage mounting area 12. A first covering structure 20 is arranged at the high-voltage mounting area 11. The first covering structure 20 has a containing recess 21 used for containing a high-voltage electrical element arranged at the high-voltage mounting area 11. A mounting structure 30 is arranged at the low-voltage mounting area 12. The mounting structure 30 is used for mounting a low-voltage electrical element. A second covering structure 40 is arranged at the low-voltage mounting area 12. The second covering structure 40 has a covering recess 41 used for containing at least part of the low-voltage electrical element. The first covering structure 20 is arranged in an integral mode with the bearing structure 10. Thus, when a worker needs to install a protective structure to protect the electrical elements of the high-voltage mounting area 11 and the electrical elements of the low-voltage mounting area 12, the worker only needs to arrange the bearing structure 10 at the communication port of the box body 1. The first covering structure 20 is arranged at the containing recess 21 of the high-voltage mounting area 11 to contain the high-voltage electrical element arranged at the high-voltage mounting area 11. Then, the worker arranges the second covering structure 40 at the low-voltage mounting area 12. At this time, a slave module of a BMS system is arranged at the low-voltage mounting area 12 through the mounting structure 30 and is contained by the covering recess 41. Thus, the mounting assembly can separate the BMS system and the high-voltage electrical element of the battery device from an external environment, thereby improving the protection reliability of the BMS system and the high-voltage electrical element. Meanwhile, the first covering structure 20 is arranged in an integral mode with the bearing structure 10. Thus, the worker only needs to arrange the second covering structure 40, without the need to arrange the first covering structure 20 and the second covering structure 40 respectively. This reduces the installation steps of the worker, avoids the misarrangement of the first covering structure 20 and the second covering structure 40, reduces the labor intensity of the worker, improves the installation efficiency of the worker, and further improves the installation efficiency of the worker.

[0054] In the embodiment, the bearing structure 10 is a sheet metal part. The bearing structure 10 is arranged in a plate shape.

[0055] As Figure 3As shown, the second cover structure 40 has a plurality of mounting holes 42, which are arranged around the cover recess 41, and the low-voltage mounting area 12 has a plurality of corresponding holes 1211, which are arranged one-to-one with the plurality of mounting holes 42. In this way, the one-to-one arrangement of the plurality of corresponding holes 1211 and the plurality of mounting holes 42 enables the bolts to simultaneously fix the second cover structure 40 and the bearing structure 10, which, compared with the way of first fixing the bearing structure 10 and then fixing the second cover structure 40 on the bearing structure 10, can reduce the number of threaded holes, realize one hole with multiple uses, reduce the structural complexity of the installed assembly, simplify the operation steps of the workers, and further improve the work efficiency of the workers.

[0056] As shown in Figures 3 to 5 , the mounting structure 30 is a plurality of, which are arranged at intervals along the first preset direction. In this way, the mounting structure 30 is arranged in a manner that enables the low-voltage mounting area 12 to install more low-voltage electrical components, and the plurality of low-voltage electrical components can share the operation data and current of the battery assembly, thereby ensuring the operation reliability and efficiency of the BMS system. At the same time, when one of the plurality of low-voltage electrical components fails, the other low-voltage electrical components can operate normally to ensure the normal operation of the battery device.

[0057] In this embodiment, the first preset direction is consistent with the length direction of the bearing structure 10.

[0058] In this embodiment, the mounting structure 30 is two, which are arranged at intervals along the length direction of the bearing structure 10.

[0059] It should be noted that the number of mounting structures 30 is not limited to this, and can be adjusted according to the working conditions and use requirements. Optionally, the number of mounting structures 30 is three, or five, or six, or eight, or a plurality.

[0060] As shown in Figure 5 and Figure 7As shown, the high-pressure mounting area 11 further has a plurality of fixing holes 111, the plurality of fixing holes 111 are divided into a plurality of groups, the fixing holes 111 in each group are arranged along a first preset direction, and the fixing holes 111 in each group are arranged along a second preset direction. The second preset direction is arranged at an angle with the first preset direction. In this way, the staff installs the high-pressure mounting area 11 of the bearing structure 10 at the communication port by passing the fastener through the plurality of fixing holes 111, so that the high-pressure mounting area 11 and the low-pressure mounting area 12 of the bearing structure 10 are both installed at the communication port by the fastener, which ensures the installation stability of the bearing structure 10, thereby ensuring the bearing reliability and stability of the bearing structure 10. At the same time, the plurality of fixing holes 111 divided into a plurality of groups can improve the installation stability and reliability of the bearing structure 10.

[0061] In the embodiment, the second preset direction is consistent with the width direction of the bearing structure 10.

[0062] Specifically, the second preset direction is arranged at an angle of 90° with the first preset direction.

[0063] As shown in Figure 3 and Figure 5 The low-pressure mounting area 12 has a connecting portion 121 and a hollow portion 122, the connecting portion 121 is connected with the high-pressure mounting area 11; and the mounting structure 30 is arranged on the connecting portion 121, and the connecting portion 121 has a plurality of corresponding holes 1211 arranged around the hollow portion 122. In this way, the low-pressure mounting area 12 is connected with the high-pressure mounting area 11 and the mounting structure 30 through the connecting portion 121, and the fastener is installed on the low-pressure mounting area 12 through the corresponding holes 1211 on the connecting portion 121, which ensures the installation reliability and connection reliability of the low-pressure mounting area 12. At the same time, the setting mode of the hollow portion 122 is beneficial on the one hand for the wire harness of the battery device to connect the battery assembly and the external equipment through the hollow portion 122, which ensures the connection reliability of the wire harness and improves the operation stability of the battery device; on the other hand, the weight of the bearing structure 10 can be reduced while ensuring the heat dissipation reliability of the battery device, which realizes the lightweight design of the bearing structure 10, thereby realizing the lightweight setting of the battery device.

[0064] As shown in Figures 3 to 7As shown, the mounting structure 30 includes at least two mounting pieces 31, which are arranged on the connecting portion 121 in a spaced manner, and the mounting piece 31 has a first matching portion 3111a, which is a matching protrusion with one of the second matching portions of the low-voltage electrical element, and is a matching recess with the other one of the second matching portions, and the matching protrusion is inserted into the matching recess to be clamped and matched with the matching recess. In this way, the mounting structure 30 realizes the connection with the low-voltage electrical element through the two mounting pieces 31, and the connection between the two mounting pieces 31 and the low-voltage electrical element is realized through the first matching portion 3111a, so that the mounting structure 30 can not only realize the mounting reliability, but also reduce the occupied space of the low-voltage electrical element, ensure that the wire harness can normally pass through the hollow portion 122, and also ensure the lightweight design of the mounting assembly. At the same time, the setting mode of the first matching portion 3111a and the second matching portion makes the processing mode of the first matching portion 3111a and the second matching portion more flexible and diverse to adapt to different working conditions and use requirements, and improves the processing flexibility of the workers.

[0065] In the embodiment, the first matching portion 3111a is a protrusion, and the second matching portion is a recess.

[0066] Specifically, the first matching portion 3111a is in the form of a rod, and the second matching portion is in the form of a through hole, so that the low-voltage electrical element is hung on the rod-shaped first matching portion 3111a through the through hole.

[0067] In the embodiment, the number of the first matching portion 3111a is two.

[0068] It should be noted that the number of the first matching portion 3111a is not limited to this, and can be adjusted according to the working conditions and use requirements. Optionally, the number of the first matching portion 3111a is three, or four, or six, or a plurality.

[0069] In the embodiment, the mounting assembly further includes a buffer structure, which is sleeved on the first matching portion 3111a, and at least part of the buffer structure is made of an elastic material. In this way, when the first matching portion 3111a is clamped with the second matching portion, the buffer structure is located between the first matching portion 3111a and the second matching portion, which can buffer the impact force between the low-voltage electrical element and the first matching portion 3111a when the low-voltage electrical element is impacted by external force, avoids the hard impact between the low-voltage electrical element and the first matching portion 3111a, and prolongs the service life of the low-voltage electrical element; on the other hand, the friction force between the low-voltage electrical element and the first matching portion 3111a is increased, which plays a role of anti-skid, and improves the installation stability and reliability of the low-voltage electrical element.

[0070] In an embodiment not shown in the drawings, the first fitting part is a recess, the second fitting part is a protrusion, and the buffer structure is sleeved on the second fitting part.

[0071] As shown in Figure 5 and Figure 6 The connecting part 121 has at least two oppositely arranged first plug-in parts 1212, and the mounting piece 31 includes a main body part 311 and at least two second plug-in parts 312. The main body part 311 has a first fitting part 3111a. The at least two second plug-in parts 312 are arranged on both ends of the main body part 311, and the at least two second plug-in parts 312 are arranged one by one corresponding to the at least two first plug-in parts 1212. Among them, one of the first plug-in part 1212 and the second plug-in part 312 is a plug-in protrusion, and the other of the first plug-in part 1212 and the second plug-in part 312 is a plug-in recess, and the plug-in protrusion is inserted into the plug-in recess to be clamped with the plug-in recess. In this way, the above-mentioned arrangement of the first plug-in part 1212 and the second plug-in part 312, on the one hand, realizes the connection between the mounting piece 31 and the connecting part 121, ensures the installation reliability of the mounting piece 31, at the same time, simplifies the installation difficulty of the worker, improves the installation efficiency of the worker; on the other hand, makes the processing mode of the first plug-in part 1212 and the second plug-in part 312 more flexible and diverse, so as to adapt to different working conditions and use requirements, and improve the processing flexibility of the worker.

[0072] In this embodiment, the second plug-in part 312 is a protrusion, and the first plug-in part 1212 is a recess.

[0073] In an embodiment not shown in the drawings, the first plug-in part 1212 is a recess, and the second plug-in part 312 is a protrusion.

[0074] In this embodiment, the number of the second plug-in part 312 is two.

[0075] It should be noted that the number of the second plug-in part 312 is not limited to this, and can be adjusted according to the working condition and use requirement. Optionally, the number of the second plug-in part 312 is three, or four, or six, or more.

[0076] As shown in Figure 6As shown, the main body part 311 comprises a first main body segment 3111, a second main body segment 3112 and a third main body segment 3113 connected with each other, the second main body segment 3112 is located between the first main body segment 3111 and the third main body segment 3113, one end of the first main body segment 3111 away from the second main body segment 3112 is connected with the second plug-in part 312, and one end of the third main body segment 3113 away from the second main body segment 3112 is connected with the second plug-in part 312. Among them, the first main body segment 3111 and the second main body segment 3112 are arranged at a first included angle, and the second main body segment 3112 and the third main body segment 3113 are arranged at a second included angle. In this way, the main body part 311 realizes the connection between the two plug-in parts through the first main body segment 3111 and the second main body segment 3112, and the second main body segment 3112 is arranged at an included angle between the first main body segment 3111 and the second main body segment 3112, and the second main body segment 3112 is arranged at an included angle between the second main body segment 3112 and the third main body segment 3113, so that the second main body segment 3112 deviates from the hollow part 122, so that the low-voltage electrical element arranged on the main body part 311 deviates from the hollow part 122, avoiding the low-voltage electrical element occupying the space of the hollow part 122, affecting the communication between the wire harness and the external equipment, and also making the low-voltage electrical element and the battery assembly have a certain heat dissipation space, ensuring the operation stability of the battery device.
