Description

TECHNICAL FIELD

[0001] The utility model relates to the field of electricity storage, more specifically, it relates to a battery pack maintenance panel. BACKGROUND

[0002] The maintenance panel of the battery pack is used for providing a detachable opening window of the battery pack to the outside, for replacing the faulty battery in the battery pack, thereby avoiding unpacking and reducing the air tightness damage caused by unpacking, and providing convenience for fault source seeking and BMU maintenance and debugging.

[0003] The existing maintenance panel only has the role of being disassembled to provide a maintenance window, and during the assembly process of the battery pack, the communication interface, the pressure relief valve and other components are generally installed on the box cover, which leads to the need to connect the communication interface before installing the box cover. Since the box cover has large volume and mass, this way of connecting the communication interface in advance not only limits the flexibility of installing the box cover, but also increases the risk of mutual scratching of the communication interface, the pressure relief valve and other components with the components in the pack, and hides unknown safety hazards. In addition, if the components installed on the box cover are damaged, the box cover must be removed, which is complicated, time-consuming and laborious, and also damages the sealing performance of the battery pack. SUMMARY

[0004] The utility model overcomes the deficiency that the communication interface and the fire fighting interface in the existing battery pack are installed on the box cover to affect the flexibility of installing the battery pack, and provides a battery pack maintenance panel, which installs the communication interface and the fire fighting interface on the movable maintenance panel, thereby improving the flexibility of installing the box cover and reducing the risk of interference and scratching of these components with the components in the pack.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A battery pack maintenance panel, comprising a panel body, a communication interface, a fire fighting nozzle, a pressure relief valve and a fire detector, the communication interface is connected with the BMS of the battery pack, the fire fighting nozzle is connected with a fire fighting pipeline, and the fire detector is arranged on the inner side of the panel body and electrically connected with the communication interface.

[0007] By integrating the communication interface, the fire fighting nozzle, the pressure relief valve and the fire detector on the panel body, these interfaces or components are no longer installed on the box body, so that they will not be interfered by the communication interface, the fire fighting nozzle, the pressure relief valve and the fire detector during the process of installing the battery and other components on the box body, thereby reducing the difficulty of assembly.

[0008] After installing the battery and related accessories, connect the communication interface, fire nozzle, pressure relief valve, and fire detector to their respective interfaces on the panel body, and then install the panel body onto the maintenance window of the case cover. This structure and corresponding operating method reduce the risk of interference or scratches between these components and internal parts of the case.

[0009] Preferably, the communication interface, pressure relief valve, fire detector, and fire nozzle are sequentially installed on the panel along its length, with the pressure relief valve located in the middle of the panel body and the fire nozzle and communication interface located on either side of the panel body. This structure separates the fire nozzle and communication interface. Since these two interfaces need to connect to external pipelines, and these pipelines are relatively thick, placing the two interfaces on the left and right sides avoids pipeline interference.

[0010] Preferably, the communication interface includes a communication inlet interface, a fire communication interface, and a communication outlet interface along the width of the panel body. The fire communication interface separates the communication inlet harness and the communication outlet harness, preventing interference between the electrical signals of the two harnesses.

[0011] Preferably, the panel body is a protruding sheet metal part, and a suspended pressure strip is provided on the back of the panel body along the width direction. The internal wiring harness of the battery pack connected to the communication interface passes under the suspended pressure strip. The suspended pressure strip constrains the internal wiring harness of the battery pack, forming a good wiring route and avoiding wire harness entanglement and friction that could lead to surface wear and failure.

[0012] Preferably, the two ends of the suspended pressure strip are fixedly connected to the side wall formed by the protrusion of the panel body.

[0013] Preferably, the panel body has a recessed reinforcing area, in which the communication interface, fire nozzle, pressure relief valve, and fire detector are located. The recessed reinforcing area and the convex portion form an I-shaped reinforcing structure, thereby reliably supporting the aforementioned components with a thinner panel body.

[0014] Preferably, the concave reinforcing area is wide on both sides and narrow in the middle, with the communication interface, fire nozzle, and fire detector located on both sides.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The communication interface, fire nozzle, pressure relief valve and fire detector are integrated on the panel body, reducing the number of parts on the battery pack box, improving the flexibility of the box cover installation, and reducing the risk of interference and scratches between these parts and the parts inside the pack;

[0017] (2) The reasonable arrangement of communication interface, fire nozzle, pressure relief valve and fire detector can reduce the probability of interference between components. Attached Figure Description

[0026] Embodiments:

[0027] A battery pack maintenance panel, as shown in Figure 1 , 3 shown, comprising a panel body 1, a communication interface 2, a fire nozzle 3, a pressure relief valve 4 and a fire detector 5, the communication interface 2 is connected to the BMS of the battery pack, the fire nozzle 3 is connected to the fire pipeline, and the fire detector 5 is arranged on the inner side of the panel body 1 and is electrically connected to the communication interface 2.

[0028] In some embodiments, the communication interface 2, the pressure relief valve 4, the fire detector 5 and the fire nozzle 3 are sequentially installed on the panel along the length direction, the pressure relief valve 4 is located at the middle position of the panel body 1, and the fire nozzle 3 and the communication interface 2 are located on both sides of the panel body 1. The structure separates the fire nozzle 3 and the communication interface 2, both interfaces need to be connected to the external pipeline, and the external pipeline is relatively thick, so that the two interfaces are arranged on the left and right sides to avoid pipeline interference.

[0029] In the width direction of the panel body 1, the communication interface 2 includes a communication inlet interface 21, a fire communication interface 22, and a communication outlet interface 23. The communication inlet wire harness and the communication outlet wire harness are separated through the fire communication interface 22 to avoid interference between the electrical signals of the two wire harnesses.

[0030] As shown Figure 2 in FIG., the panel body 1 is a convex sheet metal part, and a suspended bead 7 is provided on the back of the panel body 1 along the width direction. The internal wire harness of the battery pack connected to the communication interface 2 passes under the suspended bead 7. The suspended bead 7 restricts the internal wire harness of the battery pack to form a good wire routing, avoiding the failure of the wire harness due to winding and friction resulting in skin abrasion. Both ends of the suspended bead 7 are fixedly connected to the side walls formed by the convexity of the panel body 1.

[0031] The panel body 1 is provided with a concave reinforcing area 6, and the communication interface 2, the fire nozzle 3, the pressure relief valve 4, and the fire detector 5 are located in the concave reinforcing area 6. The concave reinforcing area 6 and the convex part form an I-shaped reinforcing structure, so as to reliably carry the above-mentioned components with a thinner panel body 1.

[0032] Both sides of the concave reinforcing area 6 are wide and the middle is narrow, showing a dumbbell shape, and the communication interface 2, the fire nozzle 3, and the fire detector 5 are located on both sides.

[0033] By integrating the communication interface 2, the fire nozzle 3, the pressure relief valve 4, and the fire detector 5 on the panel body 1, these interfaces or components are no longer installed on the box body, so that they will not be interfered by the communication interface 2, the fire nozzle 3, the pressure relief valve 4, and the fire detector 5 during the installation of the battery and other components on the box body, thereby reducing the assembly difficulty.

[0034] After the installation of the battery and the corresponding accessories is completed, then connect the communication interface 2, the fire nozzle 3, the pressure relief valve 4, and the fire detector 5 to the corresponding interfaces on the panel body 1, and install the panel body 1 on the maintenance window of the box cover. The above structure and the corresponding operation method reduce the risk of interference and scratching between these components and the components inside the package.

[0035] The above embodiments are only preferred solutions of the present invention, and do not impose any form of limitation on the present invention. There are other variations and modifications without exceeding the technical solutions recorded in the claims.
