As shown in FIGS. 8-13, the battery module 1000 includes a box and a main body 1200 installed in the box. The box includes a top cover 1100 and a bottom cover 1300. In some embodiments, the top cover 110, the main body 1200, and the bottom cover 1300 may be connected by means such as bolt connection, snap connection, etc., such that the main body 1200 of the battery module may be accommodated in the box.

Embodiment 1

Referring to FIGS. 3-5, the main body 1200 of the battery module provided by some embodiments of the present disclosure includes: a battery pack 104, a cells contact system (CCS) assembly 1, and a collection module 106.

The battery pack 104 is installed in the box and includes a plurality of battery cells 103.

The CCS assembly 1 includes a collection line 11 configured to be electrically connected to the plurality of battery cells 103 and a connection circuit board 12 connected to one end of the connection line 11.

The collection module 106 includes a mounting bracket 2 and a cell supervision circuit (CSC) assembly. The mounting bracket 2 is installed in the box and is opposite to the battery pack 104. The CSC assembly is disposed on a side of the mounting bracket 2 and is directly electrically connected to the connection circuit board 12.

In some embodiments, referring to FIG. 2, the battery pack 104 includes a plurality of battery cell rows 105, the plurality of battery cell rows 105 are spaced apart from each other along a width direction of a connection structure 101, and each battery cell row 105 includes a plurality of the battery cells 103 which are arranged at intervals along a length direction of the connection structure 101.

Under the circumstances that multiple modules in the battery pack are connected in series in the prior art, after collecting voltages and temperature signals of the modules, a CCS assembly communicates with a CSC assembly through intermediate wiring harnesses, resulting in numerous wiring harnesses and complicated assembly. By arranging the mounting bracket 2 opposite to the plurality of battery cells 103 herein, the mounting bracket 2 is configured to be closer to the CCS assembly 1, and a distance between the connection circuit board 12 and the CSC assembly is shortened, thereby facilitating direct connection between the connection circuit board 12 and the CSC assembly mounted on the mounting bracket 2, eliminating the need for any intermediate transfer wiring harness between the connection circuit board 12 and the CSC assembly. Such structure is simple and easy to assemble.

Embodiment 2

Referring to FIGS. 3-5, a battery module provided by some embodiments of the present disclosure includes a box, a battery pack 104, a plurality of CCS assemblies 1, and a collection module 106.

The battery pack 104 is disposed in the box and includes multiple battery cells 103. The battery cells 103 may be cylindrical batteries or prismatic batteries. The following embodiments will be described using cylindrical batteries as an example.

Each CCS assembly 1 include a collection line 11 configured to be electrically connected to a plurality of the battery cells 103 and a connection circuit board 12 connected to one end of the connection line 11.

The collection module 106 includes a mounting bracket 2 and a plurality of cell supervision circuit (CSC) assemblies. The mounting bracket 2 is installed in the box and is opposite to the battery pack 104. The CSC assemblies are each located on a side of the mounting bracket 2 and directly electrically connected to a corresponding connection circuit board 12.

Referring to FIGS. 6-7, the plurality of CSC assemblies include one or more first CSC assemblies 3 and one or more second CSC assemblies 4. Each first CSC assembly 3 is disposed on a first mounting surface 21 of the mounting bracket 2, and each second CSC assembly 4 is disposed on a second mounting surface 22 of the mounting bracket 2. In this embodiment, two first CSC assemblies 3 are provided on the first mounting surface 21, and one second CSC assembly 4 is located between the two first CSC assemblies 3, and the second CSC assembly 4 and the two first CSC assemblies 3 are in a staggered arrangement. By arranging the plurality of CSC assemblies respectively on the first mounting surface 21 and the second mounting surface 22, a utilization ratio of mounting space of the mounting bracket 2 may be improved and a volume of the battery module may be reduced. In addition, the staggered arrangement of the CSC assemblies on the first mounting surface 21 and the second mounting surface 22 helps reduce thermal impact between the CSC assemblies and improve heat dissipation efficiency.

In some embodiments, each CSC assembly may include a collection plate 30 and a connector provided on one side of the first collection plate 30, and the connector is electrically connected to a corresponding connection circuit board 12. For example, each first CSC assembly 3 includes a first collection plate 31 and a first connector 32 provided on a side of the first collection plate 31. As another example, the second CSC assembly 4 includes a second collection plate 41 and a second connector 42 provided on a side of the second collection plate 41. The first mounting surface 21 is provided with a plurality of first fixing protrusions 211, and the second mounting surface 22 is provided with a plurality of second fixing protrusions 221. The first collecting plates 31 are each bolted to corresponding one or more of the plurality of first fixing protrusions 211 and maintain a distance from the first mounting surface 21. The second collection plate 41 is bolted to corresponding one or more of the plurality of second fixing protrusions 221 and maintains a distance from the second mounting surface 22.

Specifically, each of the first connectors 32 and the second connector 42 is electrically connected to the connection circuit board 12 of a corresponding CCS assembly 1. The first connectors 32 are each located between the corresponding first collection plate 31 and the first mounting surface 21, and the second collection plate 41 is located between the second connector 42 and the second mounting surface 22, to maximize mounting space on the mounting bracket 2 and facilitate the electrical connection between each of the first connectors 32 and the second connector 42 and the corresponding connection circuit board 12.

Referring to FIGS. 6-7, each first connector 32 is provided with a first connection socket 321 opening toward the corresponding CCS assembly 1, and the second connector 42 is provided with a second connection socket 421 opening toward the corresponding CCS assembly 1. The connection circuit board 12 of the CCS assembly 1 corresponding to a first connector 32 is inserted into the first connector 32. The connection circuit board 12 of the CCS assembly 1 corresponding to a second connector 42 is inserted into the second connector 42. Compared to the prior art where the collection lines need to extend to the side portion of the battery pack (for example, the connection sockets 321 or 421 is arranged to open toward a side of the mounting bracket 2 in its thickness direction), the collection lines 11 herein do not need to be bent too many times, thereby reducing damage to the collection lines 11.

Referring to FIG. 6-7, the second mounting surface 22 is provided with two fixing lugs 23 and two mounting lugs 24. The two mounting lugs 24 are located between the two mounting lugs 23. A surface of any one of the mounting lugs 24 facing the other mounting lug 24 is provided with a slit 241, and the slit 241 extends through the mounting lug 24 in a direction away from the second mounting surface 22.

The second CSC assembly 4 further includes a heat conductive member including a first heat conductive structure 60. The first heat conductive structure 60 includes a first heat conductive sheet 6 and a second heat conductive sheet 5.

The first heat conductive sheet 6 includes a second section 62 and a first section 61 and a third section 63 that are respectively connected to two ends of the second section 62. The first section 61 is arranged opposite to the second mounting surface 22.

The third section 63 is arranged at an angle with the second mounting surface 22. A middle portion of the third section 63 is connected to one end of the second section 62, and two ends of the third section 63 are disposed in the two slits 241 respectively. The first heat conductive sheet 6 is located between the two mounting lugs 24 and interference-fit with the two mounting lugs 24 and the mounting bracket 2. The second heat conductive sheet 5 is connected in a heat conductive manner between the third section 63 and a bottom of the box. The bottom of the box may be a crossbeam (i.e., a crossbeam 1310 of the bottom cover 1300) at the bottom of the box. The heat on the second collection plate 41 is transferred to the box through the first heat conductive sheet 6 and the second heat conductive sheet 5.

The reason for splitting the first heat conductive structure into the first heat conductive sheet 6 and the second heat conductive sheet 5 is that a limited volume of each mounting lug 24 makes it inconvenient to provide a larger slit 241 for both the third section 63 of the first heat conductive sheet 6 and the second heat conductive sheet 5 to snap in. Thus, only the third section 63 of the first heat conductive sheet 6 is disposed into the slit 24. Furthermore, a thickness of the second heat conductive sheet 5 may be adjusted according to a distance between the third section 63 and the bottom of the box for a smooth transfer of heat.

Specifically, the heat conductive member further includes a plurality of second heat conductive structures 70. In this embodiment, three second heat conductive structures 70 are provided, where two of the three second heat conductive structures 70 are respectively corresponding to the two first CSC assemblies 3, and each of the two second heat conductive structures 70 is provided between a surface of the first collection plate 31 of a corresponding first CSC assembly 3 away from the first mounting surface 21 and a side wall (for example, an inner wall of a left side of the bottom cover 1300, referring to FIG. 8 and FIG. 10) of the box; and one of the three second heat conductive structure 70 is connected in a heat conductive manner between the first section 61 of the first heat conductive sheet 6 and the second collection plate 41. More specifically, in this embodiment, the material of the second heat conductive structures 70 is heat conductive foam 7 which plays the role of heat conduction on the one hand, and the role of buffering external impact on the other hand.

In some embodiments, the two fixing lugs 23 are bolted to the crossbeam 1310 (as shown in FIG. 8) of the box. Specifically, the first mounting surface 21 of the mounting bracket 2 is further provided with buckles 8. The buckles 8 are snapped into a slot 1320 (as shown in FIG. 8) of the box. The two connection ways are used to realize fixed installation of the mounting bracket 2. The mounting bracket 2, the two fixing lugs 23, and the two mounting lugs 24 are integrally formed. In this embodiment, the third section 63 and the second mounting surface 22 form an included angle of 90°, and the first heat conductive sheet 6 and the second heat conductive sheet 5 are made of a same metal material.

Some embodiments of the present disclosure further provide a vehicle, including a battery module and a battery management system (BMS). The BMS is configured to be electrically connected to the one or more CSC assemblies to collect information of each cell and detect voltage and temperature of each cell.
