[0044] Therefore, the shell of the energy storage product needs to be distinguished between the front shell and the rear shell during installation. During product development, the front shell and the rear shell will be processed and manufactured separately. As the types and sizes of energy storage products change, the required molds will also increase accordingly, resulting in increased mold costs and complicated manufacturing processes.

[0047] In the above energy storage device 100, the cover plate 14 fixes the battery module 12, and the battery module 12 is fixed in the accommodating space 18 by closing the opening 20 through the cover plate 14. The cover plate 14 is commonly used for the two openings 20, and there is no need to design and manufacture them separately, which can reduce the manufacturing mold of the cover plate 14, thereby simplifying the processing flow, reducing the assembly difficulty, and reducing the manufacturing cost.

[0048] Specifically, the shell 10 includes a frame 16 and two cover plates 14. The frame 16 is provided with a containing space 18 and two openings 20. The functional components of the energy storage device 100 are assembled into the containing space 18 through the openings 20. Each cover plate 14 then seals a corresponding opening 20, so that the containing space 18 is relatively closed, thereby achieving packaging and protection of the functional components.

[0049] The cover plate 14 is used to be fixedly connected to the battery module 12 . After the cover plate 14 is fixed and the opening 20 is sealed, the battery module 12 can be fixed in the accommodating space 18 .

[0055] In some embodiments, the number of the first fixing members 22 is two, and the two first fixing members 22 are disposed on the same cover plate 14 or the two first fixing members 22 are disposed on two cover plates 14 respectively.

[0056] In this way, the connection between the cover plate 14 and the battery module 12 is simple and convenient.

[0057] Specifically, Fig.15 As shown, two first fixing members 22 are disposed on the same cover plate 14 and are spaced apart, so that the cover plate 14 and the battery module 12 can be fixedly connected only by one cover plate 14 , making the connection between the cover plate 14 and the battery module 12 simple and convenient.

[0058] Or, if Fig.16 As shown, two first fixing members 22 are respectively disposed on two cover plates 14. In this way, the battery module 12 is fixedly connected in the front and rear directions of the battery module 12 through the first fixing members 22 of the two cover plates 14, so that the contact position between the first fixing members 22 and the battery module 12 is more evenly stressed, thereby ensuring the reliability of the connection.

[0059] During assembly, one of the cover plates 14 can be selected to be installed with the battery module, and then the two cover plates 14 are assembled to the housing, and the battery module 12 can be assembled into the accommodating space 18 along with the cover plates 14. The cover plates 14 do not need to be distinguished between the front cover and the rear cover, which can reduce the number of steps in the design, manufacturing and assembly process, thereby simplifying the processing flow, reducing the difficulty of assembly and reducing the manufacturing cost.

When the frame 16 and the cover plate 14 are fixedly connected, the second fastener passes through the first mounting hole 38 and the second mounting hole 40 to fix the cover plate 14 and the frame 16.

[0068] See also Figure 1 In some embodiments, the energy storage device 100 includes a seal 42 , which is disposed between the cover 14 and the frame 16 .

[0069] In this way, the accommodating space 18 inside the energy storage device 100 can be relatively closed, so that the housing 10 composed of the cover plate 14 and the frame body 16 has dustproof and waterproof protection functions.

[0070] Specifically, the energy storage device 100 includes a seal 42, which is disposed between the cover plate 14 and the frame 16. When the cover plate 14 is fixed to the frame 16 to close the opening 20 of the frame 16, the seal 42 can keep the accommodating space 18 inside the energy storage device 100 relatively closed, and to a certain extent can prevent dust or liquid from entering the energy storage device 100 and causing damage to the internal components of the energy storage power supply.

[0071] In one embodiment, the sealing member 42 comprises a silicone sealing ring, which has a good waterproof sealing effect.

The heat conductor 50 and the inverter 46 are accommodated in the accommodating space 18, and the second surface 54 is in direct contact with the surface of the frame 16 facing the accommodating space 18.

[0079] In this way, the heat conducting member 50 is in direct contact with the inverter 46 and the housing 10 , which is beneficial for transferring the heat generated by the inverter 46 to the housing 10 for heat dissipation, thereby improving the heat dissipation efficiency.

[0080] Specifically, the inverter 46 is installed on the heat conductor 50, and the heat conductor 50 is installed in the accommodating space 18 in the shell 10, and the first surface 52 of the heat conductor 50 directly contacts the inverter 46, and the second surface 54 directly contacts a surface of the shell 10 facing the accommodating space 18. Therefore, the heat conductor 50 can quickly conduct the heat generated by the inverter 46 to the shell 10, and the shell 10 can achieve rapid heat dissipation by diluting the heat through convection with the external space.

[0081] In one embodiment, the housing 10 includes a metal housing, for example, the housing 10 includes an aluminum alloy housing, so that the heat dissipation effect of the housing 10 can be improved.

[0088] Specifically, Fig.11 and Fig.12As shown, the first mounting portion 56 is fixedly connected to the heat conducting member 50. The first mounting portion 56 has a hollow portion 62, which can ensure the structural strength of the first mounting portion 56, while reducing the amount of material used to manufacture the frame 16 and reducing the weight of the frame 16.

[0092] In other embodiments, the material of the heat conducting member 50 can also be other metals or materials with good thermal conductivity. Among them, a suitable material can be selected as the heat conducting member 50 according to the thermal conductivity of the material.

[0093] In some embodiments, the housing 10 is an aluminum alloy housing 10 .

[0094] In this way, the housing 10 can have better heat conduction and heat dissipation effects, and at the same time can protect the functional modules inside it.

[0095] Specifically, the heat conductor 50 is in direct contact with one surface of the housing 10. The housing 10 is made of aluminum alloy, which can better transfer heat and quickly dissipate heat and cool down. As a metal housing 10, the aluminum alloy housing 10 is relatively light in weight and has good hardness, which can protect the functional modules inside it.

[0096] In other embodiments, the material of the housing 10 can also be other metal materials, and is not limited to aluminum alloy.
