[0024] The following is for reference. Figures 1 to 3 This application describes a BMS mounting bracket and a battery according to embodiments thereof.

[0025] According to the BMS mounting bracket of the first aspect embodiment of this application, such as Figures 1 to 3As shown, it includes a mounting plate 100, two side plates 200, and a wiring structure 300.

[0026] The top and bottom surfaces of the mounting plate 100 are respectively provided with mounting structures 101. The two mounting structures 101 are used to install the BMS main control board 500 and the BMS slave control board 600. For example, the mounting structure 101 on the top surface of the mounting plate 100 can be used to install the BMS main control board 500, and the mounting structure 101 on the bottom surface of the mounting plate 100 can be used to install the BMS slave control board 600.

[0027] Two side plates 200 are respectively connected to opposite sides of the mounting plate 100. The two side plates 200 and the bottom surface of the mounting plate 100 enclose a receiving space for accommodating the BMS board below the mounting plate 100. The two side plates 200 are used to install inside the battery casing.

[0028] The wiring structure 300 is connected to the side of the mounting plate 100. The wiring structure 300 is provided with a wiring groove 301 that runs through the top and bottom. The wiring groove 301 is for routing the power lines or low-voltage lines led out from the BMS main control board 500 and the BMS slave control board 600.

[0029] In this application, the mounting plate 100 is installed inside the battery casing via two side plates 200. The top and bottom surfaces of the mounting plate 100 are respectively provided with mounting structures 101. The BMS main control board 500 and the BMS slave control board 600 can be installed on the two mounting structures 101 respectively, without the need for multiple mounting brackets, making the structure simpler. In addition, the side of the mounting plate 100 is provided with a wiring structure 300, which has a through wiring groove 301. The wiring groove 301 facilitates the routing of the lines led out from the BMS main control board 500 and the BMS slave control board 600, reducing messy wiring and tangling, and improving practicality.

[0030] refer to Figure 1 As shown, in some embodiments of this application, there are two wiring structures 300, which are located at both ends of the same side of the mounting plate 100. The two wiring structures 300 are respectively used for high-voltage lines and low-voltage lines.

[0031] In this embodiment, two wiring structures 300 are provided, with a gap between them. The two wiring structures 300 are respectively used for high-voltage lines and low-voltage lines. In this way, mutual interference between high-voltage and low-voltage lines can be avoided, which would affect the function of the BMS system and thus affect the normal use of the battery.

[0032] refer to Figure 1As shown, in some embodiments of this application, the wiring structure 300 is provided with a plurality of wiring slots 301, which are arranged along the length of the side of the mounting plate 100 where the wiring structure 300 is provided. In addition to being connected to each other via wiring, the BMS main control board 500 is generally also connected to the battery cell module via wiring, and the BMS slave control board 600 is also connected to the battery cell module via wiring.

[0033] In this embodiment, the wiring structure 300 is provided with multiple wiring grooves 301. The multiple wiring grooves 301 are arranged along the length direction of the side of the mounting plate 100 where the wiring structure 300 is provided, which makes it more convenient to route various lines and makes wiring more convenient.

[0034] refer to Figure 1 As shown, in some embodiments of this application, the BMS mounting bracket further includes a partition 400, which is located below the mounting plate 100. The bottom end of the side plate 200 is bent to form a first connecting plate 201, which is attached to the top surface of the partition 400 and connected to the partition 400 by fasteners.

[0035] During assembly, the separator 400 is connected to the battery casing and located above the cell module. The first connecting plate 201 at the bottom of the side plate 200 is attached to the top surface of the separator 400 and connected to the separator 400 by fasteners. This makes it easier to install the mounting plate 100. In addition, the separator 400 can also separate the BMS system from the cell module, reducing the risk of leakage.

[0036] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, a wire fastener 302 is provided in the wiring trough 301. The wire fastener 302 is used to clamp the high-voltage or low-voltage wires with the inner wall of the wiring trough 301. For example, multiple wire fasteners 302 can be provided in the wiring trough 301, and the multiple wire fasteners 302 can be arranged vertically.

[0037] In this embodiment, a wire fixing buckle 302 is provided in the wiring trough 301. The wire fixing buckle 302 can cooperate with the inner wall of the wiring trough 301 to clamp the high-voltage or low-voltage wires, reduce the free shaking of the high-voltage or low-voltage wires, and make wiring more convenient.

[0038] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the partition 400 is provided with a through groove 401 extending vertically, and the bottom end of the wiring structure 300 passes through the through groove 401. That is, the bottom end of the wiring structure 300 extends into the installation space of the battery cell module.

[0039] In this embodiment, this configuration makes it easier to route the high-voltage or low-voltage lines connecting the BMS main control board 500, the BMS slave control board 600, and the battery cell module.

[0040] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, the wiring structure 300 abuts against the inner wall of the relief groove 401.

[0041] In this embodiment, this configuration reduces vibration of the wiring structure 300 during vehicle operation, resulting in a more stable connection and a longer service life.

[0042] refer to Figure 2 and Figure 3 As shown, in some embodiments of this application, at least one wire securing clip 302 in the wiring trough 301 is located below the partition 400. For example, multiple wire securing clips 302 may be provided in the wiring trough 301, with the lowest wire securing clip 302 located below the partition 400 and the remaining wire securing clips 302 located above the partition 400.

[0043] In this embodiment, this configuration makes it easier to route the high-voltage or low-voltage lines connecting the BMS main control board 500, the BMS slave control board 600, and the battery cell module.

[0044] refer to Figure 1 As shown, in some embodiments of this application, second connecting plates 402 are provided on opposite sides of the partition 400. The second connecting plates 402 are bent outward to form a horizontal plate 403, and the end of the horizontal plate 403 away from the partition 400 is bent upward to form a vertical plate 404. The vertical plate 404 is provided with a connecting hole 405. For example, the horizontal plate 403 can be horizontally arranged, the vertical plate 404 can be vertically arranged, and the portion of the second connecting plate 402 between the horizontal plate 403 and the partition 400 can be vertically arranged. The vertical plate 404 is provided with a connecting hole 405 and is connected to the side wall of the battery casing by fasteners through the connecting hole 405.

[0045] In this embodiment, the partition 400 has a second connecting plate 402 on both sides opposite to each other, and the second connecting plate 402 has a bent plate structure. In this way, it can undergo elastic deformation, which not only makes it easier to connect the battery casing, but also makes it suitable for situations where there are slight errors in the size of the battery casing. In addition, it can absorb vibration energy, reduce the vibration of the BMS system, and make the BMS system have a longer service life.

[0046] refer to Figures 1 to 3As shown, in some embodiments of this application, the mounting structure 101 includes a plurality of mounting posts 102, which are connected to the top or bottom surface of the mounting plate 100. A mounting hole 103 is provided at the end of each mounting post 102 away from the mounting plate 100. The BMS main control board 500 and the BMS slave control board 600 are connected to the mounting posts 102 by fasteners inserted into the mounting holes 103.

[0047] In this embodiment, the mounting structure 101 includes multiple mounting posts 102, which not only makes it easier to install the BMS main control board 500 and the BMS slave control board 600, but also allows for a gap between the BMS main control board 500, the BMS slave control board 600 and the mounting plate 100, that is, a heat dissipation space, thereby improving the heat dissipation effect of the battery and preventing damage to the internal structure of the battery, especially the BMS system, due to high temperature.
