Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to an integrated busbar and a battery pack. Background Art

[0002] The CCS assembly (integrated busbar) is generally composed of FPC (flexible printed circuit), busbars, isolation plates and other components. It connects the battery poles, conducts the battery cells, transfers electric energy, isolates the battery poles from the low-voltage wiring harness, and transmits the collected battery temperature and battery voltage signals to the BMS (battery management system).

[0003] The integrated slave board in the battery pack can transmit the collected battery temperature, battery voltage and other information to the BMS of the battery pack. The integrated slave board replaces the original FPC low-voltage outlet seat and the hard board connection, and directly outputs the collected data information to the BMS main board, thereby saving the cost of the low-voltage outlet seat, reducing the weight of the wiring harness in the battery pack, and improving space utilization.

[0004] Since the size of the integrated slave board is larger than the low-voltage outlet seat and is difficult to fix, in the related art, the integrated slave board is fixed on the isolation plate to achieve fixation of the integrated slave board. However, the integrated slave board will vibrate with the vibration of the isolation plate and will detach from the isolation plate when the battery expands thermally, which seriously affects the service life of the integrated slave board. Utility Model Content

[0005] In view of this, the utility model provides an integrated busbar and battery pack to solve the problem that the integrated slave board will vibrate with the vibration of the isolation plate and will separate from the isolation plate when the battery expands thermally, seriously affecting the service life of the integrated slave board.

[0038] By providing the protective bracket 3, the integrated slave board 4 can be fixed and separated from the isolation board 1, which makes the integrated slave board 4 more resistant to vibration and impact when subjected to battery cell expansion and vibration, thereby improving the service life of the integrated slave board 4; thereby facilitating understanding the working status of the battery pack or the entire battery pack.

[0039] In a specific implementation, the flexible printed circuit board 6 is located on a side of the protective bracket 3 facing away from the isolation plate 1 , and is welded to the integrated slave board 4 and the bus bar 5 .

[0040] In a specific embodiment, a plurality of busbars 5 are provided, and each two adjacent battery cell poles 2 are connected to a busbar 5 , and the plurality of busbars 5 are all welded to the flexible printed circuit board 6 .

[0041] In one embodiment, the protective bracket 3 is provided with a first support member 31 protruding from the side surface close to the isolation plate 1, and the isolation plate 1 is provided with a clearance hole 12. The first support member 31 passes through the clearance hole 12 and is suitable for connecting with the battery cell top cover 7; and in the second direction, the height of the first support member 31 is greater than the thickness of the isolation plate 1.

[0042] By arranging a first support member 31 on the protective bracket 3 and providing a clearance hole 12 on the isolation plate 1, it is possible to avoid contact between the first support member 31 and the isolation plate 1, and at the same time, the support of the protective bracket 3 by the battery cell top cover 7 can be achieved, thereby ensuring the installation stability of the protective bracket 3; and the height of the first support member 31 is greater than the height of the isolation plate 1, so that the protective bracket 3 and the isolation plate 1 can be separated.

The two baffles 35 are respectively arranged on both sides of the main body 32 along the first direction, and the distance between the two baffles 35 is adapted to the width of the integrated slave board 4. When the integrated slave board 4 is installed to the main body 32, the height of the baffle 35 is greater than or equal to the thickness of the integrated slave board 4, so as to protect the integrated slave board 4, which not only effectively prevents the integrated slave board 4 from accidental impact or wear during use, but also ensures a stable connection between the integrated slave board 4 and the main board. It should be noted that each baffle 35 can be an integrally arranged long strip, or can be arranged by a plurality of sub-baffles at intervals, and the embodiment of the present application does not impose too many restrictions on this.

[0056] By setting a first gap between the limiting hole 34 and the battery cell pole 2, errors generated during the manufacturing and installation of the limiting hole 34 or the battery cell pole 2, such as size error, shape error and position error, can be compensated, thereby ensuring the normal installation of the limiting hole 34 and the battery cell pole 2; and by setting the first gap, it can also be ensured that during use, the limiting hole 34 and the battery cell pole 2 will not cause excessive wear or damage due to friction or vibration, thereby improving the durability and reliability of the protective bracket 3 and the battery cell pole 2, and preventing the protective bracket 3 from being affected by the vibration of the battery cell pole 2.

[0057] In one embodiment, a width of one of the first gaps is less than or equal to 0.5 mm.

[0058] By limiting the width of at least one first gap to a range less than or equal to 0.5 mm, the assembly accuracy between the protection bracket 3 and the battery cell pole 2 can be improved; and since the width of the remaining first gaps is not limited to a range less than or equal to 0.5 mm, that is, the width of the remaining first gaps can be larger, while ensuring the assembly accuracy between the protection bracket 3 and the battery cell pole 2, the installation and cooperation between the remaining battery cell poles 2 and the limiting holes 34 are facilitated, and the assemblability between the battery cell poles 2 and the limiting holes 34 can be improved.

[0059] In a specific embodiment, the width of the first gap between one limiting hole 34 and the battery cell pole 2 is less than or equal to 0.5 mm; the width of the first gap between the remaining three limiting holes 34 and the battery cell pole 2 is greater than 1 mm.

[0062] In a specific implementation, three fixing columns 322 may be provided, and the three fixing columns 322 are arranged in a triangle. Three fixing holes 41 are correspondingly provided on the integrated slave board 4 , which can ensure a stable connection to the integrated slave board 4 .

[0070] In a specific embodiment, a plurality of second support members 331 are provided, and the plurality of second support members 331 are arranged in sequence and spaced apart around the circumference of the limiting hole 34 ; by providing a plurality of second support members 331 , a relatively uniform supporting force on the bus 5 can be ensured.
