Description

Technical Field

[0001] This invention belongs to the field of base station backup batteries, and specifically relates to a novel base station backup battery management system. Background Technology

[0002] The current lithium battery pack (PACK) design used in the communications industry has the battery management system (BMS) installed inside the PACK. During operation and maintenance, if the BMS needs to be replaced, the entire PACK needs to be removed from the rack and then disassembled. In addition, due to differences in the structural design of different PACKs, the installation of BMS is incompatible and cannot be universal.

[0003] Therefore, the existing PACK operation and maintenance process has the following defects: (1) When the PACK is installed on the rack, it cannot be disassembled alone. The PACK must be removed from the rack before it can be disassembled, which is time-consuming and laborious. (2) When the PACK is removed from the rack, the BMS needs to be replaced. All the screws that connect the front cover of the PACK to the chassis need to be removed. Since the screws are distributed on the four chassis sides connected to the front cover, there are many of them, and disassembly and assembly are time-consuming and laborious.

[0004] (3) When replacing the BMS after removing the cover, it is necessary to manually plug and unplug the connection wire between the battery cell and the BMS. The connection methods of different PACKs are different, which may lead to incorrect operation or even damage to the components.

[0005] (4) The current new base station backup battery management generally adopts a highly integrated design, which improves system efficiency, but it is particularly difficult to repair once a fault occurs. The complex internal cable connection not only increases the difficulty of replacement and repair, but also usually requires on-site operation by professionally trained technicians or has to be returned to the factory for repair, which undoubtedly greatly increases the maintenance cost and time cost in actual use.

[0006] In view of this, the present invention is hereby proposed. Summary of the Invention

[0007] To address the technical problems existing in the prior art, this invention provides a novel base station backup battery management system. When replacing the BMS, the PCAK does not need to be removed from the rack, nor does the cover need to be removed; the BMS can be pulled out for replacement simply by pulling out the cover. Furthermore, no manual plugging or unplugging of connecting cables is required when replacing the BMS. This system offers advantages such as saving time and effort and avoiding misoperation.

[0008] This invention includes the following technical solutions: This invention provides a novel base station backup battery management system, comprising a housing with an opening on one side, a cover plate, a battery management system, battery cells, and a sampling board. The battery cells, sampling board, and battery management system are all housed within the housing. The opening of the housing is connected to the cover plate to seal the housing. The battery management system is embedded in the inner surface of the cover plate and is connected to the inner surface of the cover plate. The battery management system is plugged into the negative terminal of the battery cells and the sampling interface of the sampling board.

[0009] Furthermore, the battery management system is connected to the negative terminal of the battery cell via a power terminal.

[0010] Furthermore, the power terminal adopts a multi-contact copper busbar vertical connector.

[0011] Furthermore, at least two power terminals are provided, and the number of power terminals is even.

[0012] Furthermore, the battery management system is connected to the sampling interface of the sampling board via a gold finger.

No professionally trained technicians are required; ordinary maintenance personnel can complete the replacement and repair of faulty components through simple operations, which greatly reduces maintenance costs and time costs, and improves the overall reliability and service life of the system.

[0020] 3. The embedded design of the BMS panel and PACK cover in this invention, and the quick connection between the BMS and the battery cell, improve the convenience of system replacement.

Detailed Implementation

[0028] The following description provides many different embodiments or examples for implementing various features of the invention. The elements and arrangements described in the specific examples below are only for concise expression of the invention and are merely examples, not intended to limit the invention.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Combined with appendix Figure 1-6As shown, the present invention provides a novel base station backup battery management system, characterized in that it includes a housing 10 with an opening on one side, a cover plate 20, a battery management system 30, battery cells 40, and a sampling plate 50. The battery cells 40, the sampling plate 50, and the battery management system 30 are all disposed within the housing 10. The opening of the housing 10 is connected to the cover plate 20 to close the housing 10. The battery management system 30 is embedded and connected to the inner surface of the cover plate 20. The battery management system 30 is plugged into the negative terminal of the battery cells 40 and the sampling interface of the sampling plate 50, respectively.

[0031] For example, the battery management system 30 can be plugged into the negative terminal of the battery cell 40, and can also be plugged into the load P-, so that the battery management system 30 is connected in series between the negative terminal of the battery cell 40 and the load; at the same time, the battery management system 30 is plugged into the sampling interface of the sampling board 50.

[0032] It should be noted that, Figure 1-3 This is merely a structural diagram of the novel base station backup battery management system of the present invention; it does not represent its usage status.

[0033] In some embodiments, the battery management system 30 is connected to the negative terminal of the battery cell 40 via a power terminal 60.

[0034] In some embodiments, the power terminal 60 is a multi-contact copper busbar vertical connector.

[0035] In some embodiments, at least two power terminals 60 are provided, and the number of power terminals 60 is even.

[0036] For example, such as Figure 2 , Figure 3 As shown in the figure, two power terminals 60 are provided. One is used to connect to the output interface B- of the battery cell 40, and the other is used to connect to the output interface P- of the load of the battery cell 40. The output interfaces B- and P- also use power terminals 60, but the power terminals 60 provided on the battery management system 30 are female connectors, while the power terminals connected to the battery cell 40 are male connectors.

[0037] The number of power terminals 60 can be set by those skilled in the art according to current carrying requirements; for example, such as Figure 2 , Figure 3 A 100Ah battery can be equipped with two power terminals 60. One of the two power terminals 60 is used to connect to the B- terminal of the battery cell 40, and the other is used to connect to the load P-. Figure 5 As shown, the 200Ah battery can be provided with four power terminals 60, two of which are used to connect to the B- of the cell 40, and the other two are used to connect to the load P-.

[0038] In some embodiments, the battery management system 30 is connected to the sampling terminal of the sampling board 50 via gold fingers 90.

[0039] In some embodiments, the sampling board 50 is provided with an adapter board 70, and the gold fingers 90 are plugged into the adapter board 70. In use, the battery cell 40 is connected via the wire adapter board 70, which has a plug-in structure and the gold fingers 90 on the battery management system 30 for plug-in connection. For example, as... Figure 9 The diagram shown is a structural schematic of the gold finger 90.

[0040] In some embodiments, a handle 80 is provided on the outer surface of the cover plate 20. Providing a handle 80 facilitates the pulling out of the cover plate 20, further improving maintenance efficiency.

[0041] In some embodiments, two handles 80 are symmetrically arranged. This has the advantage of further improving maintenance efficiency.

[0042] In some embodiments, the handle 80 is designed to allow only one finger to pass through; this allows for BMS replacement while reducing material usage and space occupation.

[0043] It should be noted that the battery management system 30 can also be just the battery management system 30; it is just set in the panel structure, avoiding the setting of connection structures, positioning structures, such as positioning pins 100 on the battery management system 30. Setting the positioning pins 100 on the panel makes it easier to manufacture.

[0044] In some embodiments, the cover plate 20 is provided with a positioning pin 100, which is used to position the battery management system 30.

[0045] In some embodiments, the cover plate 20 and the battery management system are fixed by a support column 110, that is, the panel is provided with a support column 110, and a threaded hole is provided on the support column 110. After the battery management system 30 is embedded in the cover plate 20, the battery management system and the cover plate 20 are fixed by bolts to the threaded hole.

[0046] In some embodiments, the Phoenix terminal provided on the enclosure is an RS485 interface.

[0047] For example, one side of the box 10 has an opening smaller than the area of ​​the side, and the cover plate 20 is connected to the opening. For example, one side of the box 10 is entirely open, and a large cover plate is fixedly connected to the opening by bolts, and an opening for connecting the cover plate 20 is made on the cover plate.

[0048] For example, such as Figure 6As shown, this figure is a schematic diagram of the cover plate 20; the figure shows the connection relationship between the support column 110, the positioning pin 100 and the cover plate 20; since this figure is a side view, the positions of the support column 110 and the positioning pin 110 in the figure do not represent a limitation of the present invention.

[0049] For example, the cover plate 20 is provided with threaded holes; during transportation, the cover plate 20 is fixedly connected to the box body 10; to prevent the internal connectors from loosening during transportation.

[0050] For example, such as Figures 5-7 As shown, the dimensions of the mounting and positioning holes of the unified battery management system 30 embedded in the cover plate 20, the structural dimensions of the external communication, LED lights, DIP switches, and reset buttons; the assembly and connection structure requirements of the unified battery management system 30 embedded in the cover plate 20; and the structure requirements of the anti-foolproof pins of the unified battery management system 30 embedded in the cover plate 20.

[0051] For example, the power terminal 60 uses a multi-contact copper busbar vertical connector as the output interface of the battery cell 40B-. The terminal has a fixed structure to meet the mating requirements with the busbar of the power adapter board. For example, a schematic diagram of the layout dimensions of the power terminal 60 of the battery management system 30 is shown below. Figure 8 , Figure 9 As shown; Figure 8 As can be seen from the diagram, the power terminal 60 is connected to the power interface of the PCB board of the battery management system 30. The power terminal 60 is connected to the battery management system 30 through the power interface 120. Among them, a=19.88mm, b=1.5mm, c=31.5mm, d=18.3mm, e=15.88, f=2.9mm, g=18.75mm, h=20.95mm, i=9.5mm, j=11.32mm, and k=16.68mm. Figure 9 As can be seen from the diagram, the power terminal 60 is equipped with multiple contacts; where l=14.46mm, m=1.45mm, n=0.87mm, and o=1.23mm.

[0052] For example, the gold fingers 90 are of the dual-row pin header type, which are connected to the gold finger board 130 on the battery management system 30 by soldering. For example, the gold finger size and layout requirements are as follows... Figure 10-12 As shown, the gold fingers 90 of the double-row pin header are soldered onto the gold finger board, where p=65.3mm, q=7.5mm, r=3mm, s=3mm, t=74.6mm, u=10mm, v=33.7mm, and w=3mm. It should be noted that... Figure 12 The PCB in the middle is the PCB board of the battery management system 30, and the thickness H of the gold finger board 130 is 1.6mm.

[0053] For example, the gold fingers that plug into the adapter board 70 are fixed structures that meet the terminal plugging requirements of the sampling adapter board; the interface definition of the gold finger board used to connect the gold fingers needs to be consistent with the sampling interface on the adapter board 70.

[0054] In this embodiment, the sampling interface of the sampling board 50 is defined as shown in the following table:

[0055] In the table, DET1 / DET2 are reserved function ports, DET3 is the fire extinguisher interface, B0~B16 are the individual battery acquisition lines, HEAT- and HEAT+ are heating interfaces, and B+ and P+ are the positive terminal outputs of the individual battery and the battery pack, respectively.

[0056] For example, such as Figure 13 The diagram shows the structure of the sampling interface on the adapter board 70. This sampling interface has 50 pins, evenly arranged in two rows, with a distance D of 2.54 mm between adjacent pins.

It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.
