Technical Field
[0001] The utility model belongs to the technical field of energy storage liquid-cooled battery packs, and particularly relates to a liquid-cooled PACK with a fuse insulating cover. Background Technique
[0002] With the rapid development of the new energy industry, the demand for liquid-cooled containers is also growing rapidly. As the main component unit of liquid-cooled containers and outdoor cabinets, the safety issues of liquid-cooled PACKs have received more attention.
[0003] In the prior art, a fuse is usually installed on one side of the battery module in the liquid-cooled PACK to protect the circuit. The fuse is usually directly connected to the battery module by a copper busbar. The connection part between the copper busbar and the fuse is directly exposed to the outside. Since the other end of the copper busbar is connected to the battery module, part of the copper busbar is in a conductive state; during the subsequent installation of the remaining components by the operator, there is a risk of electric shock due to directly touching the conductive part of the connection between the fuse and the copper busbar or accidentally contacting the energized part when using tools. Content of the Utility Model
[0004] In order to make up for the deficiencies of the prior art, the utility model provides a liquid-cooled PACK with a fuse insulating cover to solve the technical problem of potential electric shock safety hazards during the installation of the liquid-cooled PACK.
[0005] To achieve the above object, the specific technical solution of the utility model is as follows:
[0006] A liquid-cooled PACK with a fuse insulating cover includes a liquid-cooled plate, an insulating cover shell, a fuse assembly, and a plurality of battery modules. The plurality of battery modules are arranged in sequence on the liquid-cooled plate. The fuse assembly includes a fuse mounting plate and a fuse. The fuse is fixed on the liquid-cooled plate through the fuse mounting plate. Each battery module is connected to the fuse through a copper busbar. The insulating cover shell is sleeved outside the fuse and is fixed to the fuse mounting plate through a detachable structure.
[0007] Further, the detachable structure is a screw connection.
[0008] Further, the bottom surface and one side surface of the insulating cover shell are open, and installation edges formed by bending are provided on both sides of the insulating cover shell. Installation holes are provided on both installation edges. Screws pass through the installation holes and are connected to the fuse mounting plate at the bottom.
[0009] Further, the insulating cover shell is fixed to the fuse mounting plate by M4x12 combination screws. The bottom end of the copper busbar is connected and fixed to the end of the fuse by M8x16 combination screws.
[0010] Further, a relief notch is provided at the top of the insulating housing. The copper bar connecting the fuse and the battery module extends out from the relief notch.
[0011] Further, the copper bar is formed by bending and is divided into a first connection section at the top, a transition section in the middle, and a second connection section at the bottom. The end of the first connection section is connected to the corresponding battery module. The end of the second connection section is connected to the corresponding end of the fuse.
[0012] Further, an insulating column matching the second connection section is fixed on the fuse mounting plate. The middle part of the second connection section is fixed to the insulating column by screws.
[0013] Further, the middle part of the second connection section is fixed to the insulating column by an M6x16 combination screw.
[0014] Compared with the prior art, the present utility model has the following advantages:
[0015] 1. In the present utility model, an insulating housing is sleeved on the fuse. The insulating housing is used to isolate the connection between the fuse and the copper bar from the outside world, forming an insulating protection, and avoiding the danger caused by the operator directly touching the conductive part of the connection or contacting the live part when using tools.
[0016] 2. By integrally arranging the fuse, the copper bar and the insulating housing on the fuse mounting plate, the present utility model enables the fuse and the insulating housing to be pre-assembled, thereby improving the assembly efficiency of the fuse and the battery module on the premise of adding the insulating housing.

[0021] The present utility model will be further described below with reference to the drawings.
[0022] As Figure 1 and 2 shown, a liquid-cooled PACK with a fuse insulating cover includes a liquid-cooled plate 1, an insulating cover housing 2, a fuse assembly, and a plurality of battery modules 6. Among them, the plurality of battery modules 6 are arranged in sequence on the liquid-cooled plate 1. The fuse assembly includes a fuse mounting plate 3 and a fuse 4. Among them, the fuse 4 is fixed on the liquid-cooled plate 1 through the fuse mounting plate 3.
[0023] Each battery module 6 is connected to the fuse 4 through a copper busbar 5. The insulating cover housing 2 is sleeved outside the fuse 4, and can form insulation protection for the connection part between the fuse 4 and the copper busbar 5, avoiding danger caused by the operator directly touching the conductive part of the connection part or contacting the live part when using tools.
[0024] The specific structure is, as Figure 2 shown, the bottom surface and one side surface of the insulating cover housing 2 are open, so that it can be quickly sleeved on one side of the fuse 4 facing the operator to provide insulation protection for the operator. A relief notch is provided at the top of the insulating cover housing 2. During installation, the copper busbar 5 connecting the fuse 4 and the battery module 6 extends out from the relief notch.
[0025] Furthermore, installation edges formed by bending are provided on both sides of the insulating cover housing 2. Mounting holes are provided on both mounting edges. Screws pass through the mounting holes to fix the insulating cover housing 2 on the fuse mounting plate 3.
[0026] In this embodiment, the insulating cover housing 2 is fixed to the fuse mounting plate 3 by using M4x12 combination screws. The bottom end of the copper busbar 5 is connected and fixed to the end part of the fuse 4 by using M8x16 combination screws.
[0027] As Figure 2 shown, the copper busbar 5 is formed by bending and is divided into a first connection section at the top, a transition section in the middle, and a second connection section at the bottom. Among them, the end of the first connection section is connected to the corresponding battery module 6. The end of the second connection section is connected to the corresponding end part of the fuse 4.
[0028] Further, an insulating column 7 that cooperates with the second connection section is fixed on the fuse mounting plate 3.
